Appearing in ''Jurassic Park''

Jurassic Park is a 1990 science fiction novel by Michael Crichton, adapted into a feature film released in 1993. As the novel opens, eccentric and wealthy entrepreneur [|John Hammond] founds a high-tech amusement park on the fictional Costa Rican island of Isla Nublar. It is filled with dinosaurs cloned with the help of DNA harvested from prehistoric insects found in amber. In order to open the park, he must first get investors and obtain insurance by gaining the approval of several experts in different fields. Hammond invites palaeontologists Alan Grant and Ellie Sattler, mathematician [|Ian Malcolm], and his investors' attorney, Donald Gennaro, to tour the park. Upon arrival, the experts begin to discover errors in the system, such as dinosaurs in the wrong pens and evidence of dinosaurs breeding in the wild. These errors occur even though Jurassic Park is being run by expert computer engineers and well-established technical systems. Soon after, because of a tropical storm and industrial sabotage by a disgruntled technician, the park undergoes several technical failures and the dinosaurs escape their enclosures. A Tyrannosaurus rex attacks the group, separating them. The staff then make a desperate attempt to regain control of the situation. As Ian Malcolm had predicted from the start, it becomes quite clear that they had never been in control. Often considered a cautionary tale on biological tinkering in the same spirit as Mary Shelley's Frankenstein, the book uses the mathematical concept of chaos theory and its philosophical implications to explain the inevitable collapse of the park.
The first two film sequels take place on Isla Sorna, a nearby island also known as "Site B", where the dinosaurs were engineered and nurtured for a few months, before being moved to Isla Nublar. Jurassic World, the third sequel, sees the story return to Isla Nublar. , the fourth sequel, also takes place on Isla Nublar.

Dr. Alan Grant

Dr. Alan Grant is the main protagonist in the first novel, and the first and third films. In the novel, he is described as a barrel-chested bearded man of forty, with a strong affinity for children, especially those interested in dinosaurs. Grant, based on paleontologists Philip J. Currie and Jack Horner, is said to be one of the world's most renowned paleontologists, specializing in hadrosaur and other duck-billed dinosaurs such as Maiasaura. His scientific achievements, including the first description of maiasaurs, are those of Horner and Robert R. Makela. In the book, Grant tells the children that he once had a wife who died years previously.
Before the events of the novel, Grant was approached by Donald Gennaro, chief counsel for InGen, to provide information on the requirements for the care of infant dinosaurs, claiming it to be for a museum exhibit. Grant agrees to Hammond's invitation to tour the park, finding it difficult to turn down the request from a major financial donor, unaware that Hammond has cloned living dinosaurs. When the creatures escape, Grant becomes stranded in the park with Hammond's grandchildren. Throughout a large portion of the book, Grant and the two children explore the park trying to find their way back to the rest of the group. In the film, much of this period is omitted, with only a few key events occurring onscreen.
In the second novel, The Lost World, Grant is only mentioned. [|Richard Levine] tells Ian Malcolm that he asked Grant about rumors that InGen was cloning dinosaurs; according to [|Levine], Grant said the rumors were "absurd". Later on, [|Ed James] mentions that Grant is on a leave of absence and lecturing in Paris about his theory that Tyrannosaurus was a scavenger. Grant is mentioned a third time when Levine criticizes Grant's theory that a Tyrannosaurus could not function in rainy climates.
The film portrays Grant differently than the novel, giving him an introverted personality and a dislike of children. However, over the course of the first film, he warms to Hammond's grandchildren. This was because Spielberg wanted to "provide a source of dramatic tension that did not exist in the novel". In the film, Grant specializes in Velociraptors, and believes that birds are closely related to dinosaurs. By the end of the film, his experience on the island changes his view of children and he decides not to endorse Jurassic Park.
He is the main protagonist of Jurassic Park III. In the years since the incident on Isla Nublar, Grant has continued his research on fossils, shrugging off the notion that such endeavors are moot with living dinosaurs on Isla Sorna by claiming that InGen's creatures are just "genetically engineered theme park monsters" and not real dinosaurs. As in the first film, his research is focused on Velociraptors and he has proposed new theories regarding raptor intelligence. Grant reluctantly agrees to join an allegedly wealthy couple for an aerial tour of Isla Sorna, Jurassic Park's "Site B", in exchange for funding for his dig site. However, the plane crashes, and they become stranded on the island. While navigating it, Grant realizes that his theories about raptors – that they have advanced intelligence and communication abilities – are correct. He escapes the island after a rescue operation.
Sam Neill will reprise his role as Dr. Alan Grant in Jurassic World: Dominion, scheduled for release in 2021.
In the Jurassic Park universe, Grant is credited with having written at least two popular books on dinosaurs, referenced by Tim Murphy in Jurassic Park and by [|Eric Kirby] in Jurassic Park III. Eric comments that the first book was better as Grant actually liked dinosaurs when he wrote it, as compared to the second written after his time in the park.

Dr. Ellie Sattler

In the novel, Dr. Ellie Sattler is a graduate student studying under Grant, and accompanies him on the tour of InGen's dinosaur preserve. She is from Montana and specializes in paleobotany. Although she is initially thrilled to see the park, she finds poisonous plants in public areas and near swimming pools, and is angered by how little attention the staff has given to reproducing prehistoric plant life. While the rest of the group returns to the Visitor Center, Ellie stays with veterinarian Dr. Harding, to take pictures of a sick Stegosaurus. After the Tyrannosaurus attack, she helps Harding care for Ian Malcolm's injuries. During the Velociraptor assault on the Visitor Center, Ellie uses herself as bait to distract the pack of raptors trying to get into the lodge. Although she survives the events of the novel, she is only briefly mentioned in its sequel, in which she is known as Ellie Sattler Reiman. It is stated that she married a physicist and gives guest lectures at his university while raising two children.
Ellie has a more prominent role in the first film than in the novel. Because of alterations to the plot in the film, Ellie does many of the things done by Donald Gennaro in the novel. In the film, it is Ellie who ventures out of the bunker with Muldoon to bring the park's power systems online. Additionally, in the film, Ellie is a doctor of paleobotany and in a relationship with Grant. Spielberg did this to add tension to the film and because he felt that she did not get enough attention in the book.
Ellie has a minor role in Jurassic Park III. According to the film, her relationship with Grant ended after the first film, but they remain close friends. She is married to [|Mark], an employee of the U.S. State Department. They have two young children and host Grant for dinner. Later, when Grant is stranded on Isla Sorna and terrorized by a Spinosaurus, it is Ellie who Grant calls for help.
Laura Dern will reprise her role as Dr. Ellie Sattler in Jurassic World: Dominion, scheduled for release in 2021.

Dr. Ian Malcolm

Dr. Ian Malcolm is a mathematician who specializes in chaos theory. His character is based on Ivar Ekeland and James Gleick. Malcolm's all-black clothing style reflects that of Heinz-Otto Peitgen, a mathematician who wrote a richly illustrated book on fractals. According to Crichton, Malcolm's character functions as the "ironic commentator inside the story who talks about the action as it takes place".
Throughout Jurassic Park, Malcolm makes several predictions based on chaos theory about the consequences and ultimate failure of attempting to control nature, which often turn out to be correct. Malcolm is seriously injured during the initial Tyrannosaurus attack and is brought back to the Visitor Center. He spends the remainder of the novel bedridden, usually under the influence of high doses of morphine, continuing to comment on the park's inherent flaws and impending collapse. Although he is declared dead at the end of the novel, he explains in the sequel that this declaration was premature. Thanks to timely intervention by Costa Rican surgeons, he survives with a permanent leg injury, requiring a cane to walk. In the film adaptation, Malcolm does not use a cane but is traumatized by his ordeals. In the first film, it is noted that he is the father of three children; one of them, [|Kelly], appears in the sequel.
Malcolm is the main protagonist of The Lost World, in which he agrees to help wealthy paleontologist Richard Levine plan an expedition to Isla Sorna, Jurassic Park's secondary site. When Levine becomes trapped on the island after going there alone, Malcolm and the remaining expedition members mount a rescue. By the time frame of The Lost World, Malcolm has become more proactive and vigorous, and has enhanced his knowledge about dinosaurs. He is again injured in a dinosaur attack but survives.
He is also the main protagonist of the film adaptation, titled The Lost World: Jurassic Park. In the four years since the incident on Isla Nublar, Malcolm loses his reputation, credibility, and university tenure due to his assertions of living dinosaurs, which InGen denies along with the entire Jurassic Park incident. Despite his animosity towards the company, Malcolm is among those hired by John Hammond to visit the island and document the dinosaurs in their natural habitat. Malcolm goes in order to rescue his girlfriend, Dr. [|Sarah Harding], who had already set out for the island. Malcolm's earlier experience with the Tyrannosaurus at Isla Nublar aids his survival, and he and Sarah work to stop a Tyrannosaurus which a rival expedition had brought to San Diego. This restores Malcolm's reputation, and the Jurassic Park survivors become renowned.
Malcolm does not appear in Jurassic Park III, but is mentioned once by Grant when he talks with Eric Kirby about a book Malcolm wrote. In Jurassic World, Malcolm's name and image briefly appear on the cover of his book God Creates Dinosaurs, which is a reference to a line in the first film that has become iconic with his character.
Malcolm returns in the 2018 film . In the film, an aged Malcolm urges the U.S. Senate to allow the last surviving dinosaurs to die in an impending volcanic eruption on Isla Nublar. He is successful in persuading them by highlighting the threats the dinosaurs pose. At the end of the film, dinosaurs are dispersed globally because of the actions done by [|Eli Mills]. Malcolm reluctantly states that humans must now co-exist with them, declaring that the world has entered a -Jurassic age as he quotes "Welcome to Jurassic World".
Jeff Goldblum will reprise his role as Dr. Ian Malcolm in Jurassic World: Dominion, scheduled for release in 2021.

John Hammond

John Hammond is the wealthy owner of Jurassic Park and founder of InGen. According to the novel and Jurassic World: Fallen Kingdom, his full name is John Alfred Hammond, but in the 1998 video game Trespasser and in a deleted scene from the second film, he is referred to as John Parker Hammond. Although he is not modeled after anyone in particular, Crichton explained in an interview that Hammond is like the "dark side of Walt Disney".

Novel history

Hammond is one of the primary antagonists in the novel and is portrayed as a cold and eccentric CEO who is only interested in making a profit and succeeding in recreating dinosaurs. When explaining to Dr. [|Henry Wu] why he chose to spend his money on an amusement park rather than helping mankind, Hammond said, "That's a terrible idea. A very poor use of new technology... helping mankind a very risky business. Personally, I would never help mankind."
In the novel, Hammond takes little responsibility for the park or its failures and instead blames others for anything that goes wrong. He concludes that the people he selected as the park's senior staff have character flaws that prevent his vision from being realized. During the events of the novel, he remains in the relative safety of the Visitor Center and his private bungalow, continuing to believe that he is in control, even as the surrounding situation grows exceedingly dire. When his grandchildren become lost in the park, he maintains his belief that order will soon be restored, and that the children are in no real danger. Near the end of the novel, it is revealed that he has no love towards his grandchildren. When the staff regains control of the park, he rationalizes the disaster in the cold manner of a corporate systems analyst, deciding that everything that has happened was merely a fluke, reflecting that everyone he hired had some personal flaw that prevented them from realizing what he was trying to achieve, and that next time he will do better. However, while outside, he is startled by a Tyrannosaurus roar, falls down a hill, and breaks his ankle. He is unable to climb up the hill and is subsequently killed by a pack of Procompsognathus.

Film history

The personality of the film's Hammond is a near opposite to the novel's version, sharing only his eccentricity. Hammond is depicted as a kind, jovial and charismatic Scottish capitalist who takes responsibility for his actions, a sympathetic and loving grandfather and leader who means well and tries to keep everyone safe. Despite valuing money, he appears less interested in profit than his novel counterpart and explicitly states that he does not want to create a park that caters to the extremely rich – he is instead concerned with sparking interest in others. The film's Donald Gennaro possesses the majority of the negative and greedy aspects of the novel's Hammond.
Hammond has a deeper emotional understanding of creating attractions for children and families, and wants to make Jurassic Park a scientific reality. He notes that his first attraction was a motorized flea circus, but for the park he wants to show visitors something real rather than an illusion. However, he is misguided in his steadfast belief that his creations are under control, as he underestimates the power of genetics and nature. He also has little regard for pure scientific research, being more interested in the applications of genetic engineering. When the security system breaks down, he and his staff work to restore power and rescue the experts and his grandchildren, while themselves remaining in a secure control room. Eventually, however, he and the other survivors ruefully leave the island, with a depressed Hammond agreeing with Grant that the park has failed and must never be endorsed.
In the second film, he is older and appears to be in failing health. He is relieved of his position as CEO, which the board of directors gives to his nephew, [|Peter Ludlow], after an accident on Isla Sorna, Jurassic Park's "Site B". The film states that Hammond had initially begun construction of Jurassic Park in San Diego, before abandoning the project in favor of the Isla Nublar location. Ludlow intends to finish the San Diego project and populate it with dinosaurs that he plans to take off of Isla Sorna. Hammond devotes what resources he has left to keeping the island's dinosaurs isolated from the rest of the world. In an attempt to stop Ludlow, Hammond sends a small party, including a reluctant Ian Malcolm, to gather a complete photo record of the animals, alive and in their natural habitats, so that he can garner enough public opinion to preserve the island and its dinosaurs from the world. Ultimately, the expedition is halted and Hammond is able to publicly advocate his idea to leave the dinosaurs in peace on the island, thinking of what Malcolm previously told him: "Life will find a way."
Hammond does not appear in the third film, but is mentioned in Grant's lecture on Velociraptors: "what John Hammond and InGen did at Jurassic Park is create genetically engineered theme park monsters".
Between July 2004 and March 2008, Attenborough said he would reprise his role for the fourth film, although his character was eventually removed. In the fourth film, Jurassic World, Hammond has been deceased for some time. A memorial statue of him is present in the new theme park known as Jurassic World. In 2014, a viral marketing website for the fictional Masrani Global Corporation was launched to promote Jurassic World. According to the website, Hammond died in 1997. [|Simon Masrani], CEO of the Masrani Corporation and the owner of Jurassic World, is stated to have been entrusted by Hammond to direct the new park and honor Hammond's beliefs.
In Jurassic World: Fallen Kingdom, Hammond was revealed to have been partners with [|Benjamin Lockwood] in the de-extinction of the dinosaurs, until Lockwood's plans to have his deceased daughter cloned with the same technology led to their falling out. A painting of Hammond appears in the film.

Lex Murphy

Alexis Murphy is Tim Murphy's sister and John Hammond's granddaughter.
In the novel, she is described as seven or eight years old, relatively outgoing, blonde and "a sporty young girl who loves baseball". She wears a baseball glove slung over her shoulder and a baseball cap just about everywhere. Lex is shown to have the traits of a stereotypical child that whines and complains. Her selfish and childish behavior often annoys the people around her and puts her and the group in danger. Throughout the novel, she shows characteristics of Hammond, such as being unkind, careless, and unappreciative of the events occurring around her.
In Spielberg's 1993 film, Lex is the older of the two siblings, aged 12–14, and has a personality similar to her brother's from the novel. In the film, Lex has advanced computer skills that help the survivors escape a pack of Velociraptors. While initially frightened by many of the dinosaurs, Lex eventually gains courage and is instrumental in rebooting the park's systems. Lex's character was strengthened, like Ellie Sattler, to add strong female roles to the film.
She makes a cameo in the second film when Ian Malcolm comes to visit Hammond. She briefly listens to Malcolm as he argues with Ludlow regarding what happened on Isla Nublar.

Tim Murphy

Tim Murphy is Lex Murphy's brother and John Hammond's grandson. In the novel, he is described as a bespectacled boy of about eleven who has an interest in dinosaurs and computers. His quick thinking and encyclopedic knowledge of dinosaurs aid the group several times, and he is instrumental in discovering that dinosaurs have escaped the island, as well as regaining the means to warn the mainland. Later, Tim's ingenuity and technical knowledge allow him to navigate the park's computer systems and to reactivate the physical security systems before the Velociraptors gain access to the visitor's lodge. His expertise regarding dinosaurs rivals Grant's, and is superior to that of Dr. Wu, the scientist who created the dinosaurs. Already familiar with his work before they meet, Tim almost immediately strikes up a friendship with Grant, who notes "it's hard not to like someone so interested in dinosaurs". Tim's father does not share his interest in paleontology, so the dinosaur-loving Grant forms an instant bond with Tim during their time in the park.
In Spielberg's film, Tim and Lex's ages are swapped and some aspects of his personality and role in the story are given to Lex. Tim is still the child interested in dinosaurs, but all of his computer knowledge is given to Lex. This was done so that Spielberg could work specifically with actor Joseph Mazzello, who was younger than Ariana Richards, and to make Lex into a stronger character.
Like Lex, Tim also makes a cameo in the second film during Ian Malcolm's visit to John Hammond.

Dr. Marty Gutierrez

Dr. Marty Gutierrez is an American biologist who lives in Costa Rica. He plays an expository role in both novels. In the first novel, he identifies an unknown lizard that attacks a little girl as Basiliscus amoratus. He is initially unhappy with this identification because the lizard was more venomous than expected and had three toes. He searches the beach where she was attacked and finds the corpse of a similar lizard in the mouth of a howler monkey, which he promptly sends for laboratory analysis. He also appears at the end of the novel, when the survivors are being held back for questioning by the Costa Rican government. He tells Dr. Grant that the survivors, with the exception of the children, will not be leaving any time soon.
In the second novel, he finds and shows Richard Levine the desiccated corpse of an unknown creature, oddly similar to the ones found prior to the Jurassic Park incident. He informs Levine that no one knows where these creatures are coming from, and the two argue about whether or not these are dinosaur remains.
Gutierrez is the only character to appear in both novels but none of the films.

Dr. Lewis Dodgson

Dr. Lewis Dodgson is the main antagonist of the Jurassic Park novels.
In the Jurassic Park universe, Dodgson is an ambitious scientist who is unafraid to make aggressive moves, generally considered to be unethical, to get what he wants, stating that he "won't be held back by regulations made for lesser souls". Dodgson works for the Biosyn Corporation, a company that rivals Hammond's and has a far spottier scientific reputation. Dodgson is described in the novels as more of a salesman than a scientist, and someone who specializes in both reverse engineering and stealing the work of others. He hopes to get his hands on Hammond's technology in order to create dinosaurs of his own. He and his company seek to clone dinosaurs not as an attraction, but as potential test subjects for laboratory applications. He is portrayed as cold, ruthless, and impatient. In the first novel, Dodgson hires Dennis Nedry to steal dinosaur embryos for Biosyn, but the plot fails when Nedry is killed by a Dilophosaurus on his way to deliver the embryos.
In the sequel novel, Dodgson is much more ambitious and takes a team to Isla Sorna in an attempt to collect fertilized dinosaur eggs. He is more of an evildoer in this novel as he attempts to murder Sarah Harding. Ignorant of the dangers of these animals, Dodgson and his team are eventually killed, with Dodgson being killed by the infant Tyrannosaurus after being captured by the adults.
Dodgson only makes a short appearance in the first film where he meets Dennis Nedry in San Jose, Costa Rica, and gives him $750,000 and an embryo transfer device disguised as a shaving cream container. For the second film, his character's profit-driven actions and naivete regarding the dinosaurs are transferred to Peter Ludlow.
The character will return for the first time in Jurassic World: Dominion, now recast with Campbell Scott due to criminal conviction of original actor Cameron Thor.

John Arnold/Ray Arnold

John Arnold is Jurassic Park's chief engineer, running the main control center from the Visitor Center. He is described as a thin chain-smoker and chronic worrier. A gifted systems engineer, Arnold had designed weapons for the U.S. military, and later worked at several theme parks and zoos before joining the Jurassic Park team. He was a grudgingly optimistic man, who maintained total faith in the computer systems and continued to believe that despite the setbacks, things would work out in the end. When Dennis Nedry locks them out of the system, Arnold, after much persuasion by Donald Gennaro, shuts off all power to the park and resets the computer-control systems. After turning the power back on, he believes the problem has been solved, when it has actually been made worse. By shutting down the main power grid, he turned off several systems that were unaffected by Nedry's lockout, including the Velociraptor paddock. Arnold realizes his mistake many hours later and volunteers to go outside to restore power to the main generator. Before he can do this, he is killed by an escaped Velociraptor.
In Spielberg's 1993 film, Arnold is referred to as "Ray", rather than John, to distinguish him from John Hammond. However, in a deleted scene from the second film, he is mentioned as "John Arnold". In the film, Arnold has a smaller role than in the novel but retains the same personality and outlook, often prefacing a risky action with the comment, "Hold on to your butts." Arnold's death is not shown on camera, but is confirmed when his severed arm falls onto Ellie's shoulder in the power shed.

Donald Gennaro

Donald Gennaro is the attorney sent on behalf of Jurassic Park's investors to investigate the safety of the park after several reports of missing or dead workers. In the novel he is described as a short muscular man and represents an "every-man" personality among the characters. Although he is initially worried only about disappointing his supervisors, he soon drops this concern when his life is threatened, focusing on survival instead. When problems begin to occur, he consistently handles them appropriately, accompanying Robert Muldoon on a mission to subdue the Tyrannosaurus and successfully restoring power, despite being ambushed by a Velociraptor. Grant claims that his negative attitude comes from trying to avoid responsibility for his role in creating the park. Near the end of the novel, Gennaro realizes that he is partially responsible for everything occurring when Grant says, "You sold investors on an undertaking you didn't fully understand... You did not check on the activities of a man whom you knew from experience to be a liar, and you permitted that man to screw around with the most dangerous technology in human history." Gennaro then helps Grant in his attempt to wipe out the remaining Velociraptors and their eggs with nerve gas. Although he survives the events on the island, he dies of dysentery sometime after.
For the film, Spielberg condenses the characters Ed Regis and Donald Gennaro and the negative aspects of the novel's Hammond into one character. The result is the creation of a character whose loyalty to his employers and seriousness toward the job they gave him is easily overtaken by his own personal greed. When the other scientists criticize Hammond's park for various reasons, Gennaro is the only one left who supports the concept, seeing great profit opportunity in the live dinosaurs. Gennaro is overcome by fear when the electric fence around the Tyrannosaurus paddock fails, and abandons Tim and Lex. Hiding in a toilet stall, he is subsequently found and eaten by the Tyrannosaurus moments after she breaks out of her pen.

Dr. Harding

Dr. Harding is Jurassic Park's chief veterinarian. In the novel, he had been the chief of veterinary medicine for the San Diego Zoo, and was the world's leading expert on avian care. He accepted the job at Jurassic Park because he wanted to become famous for writing the first textbook on the care of dinosaurs. When the group first encounters him, he is caring for an ill Stegosaurus. With the help of Ellie, he finds the source of the animal's sickness and is able to treat it. Being the only medical doctor on the island, he treats Malcolm's injuries. He is attacked by a Velociraptor during the assault on the Visitor Center, but ultimately survives his time on the island. It is implied in the second novel that Sarah Harding is his daughter.
He makes a brief appearance in the first film with a sick Triceratops.
He also appears as one of the main characters in ', a 2011 film-inspired video game in which he has a daughter named Jess. In the game, he is portrayed as being significantly younger than in the movie. While his first name is never mentioned in the novel or the film, he is referred to in Jurassic Park: The Game as Dr. Gerry Harding, and Sarah Harding is mentioned as his other daughter.

Robert Muldoon

Robert Muldoon is Jurassic Park's game warden. Described in the novel as a burly man fifty years of age, with deep blue eyes and a steel gray mustache, he is a former professional hunter who worked with Hammond at one of his previous parks in Kenya. He has experience working with dangerous predators and his attitude toward the dinosaurs is realistic and unromantic. He believes that the Velociraptors should be destroyed, describing them as smart and potentially dangerous. He also recommended that the park be equipped with more military-grade weapons for use in emergencies, but was overruled. He reminds Hammond of this when it dawns on them that they have no way of stopping the escaped T. rex. Muldoon spends most of the novel riding around the park, drinking whiskey and attempting to restore order. He is later attacked by a pack of Velociraptors, but survives by wedging himself into a pipe. He manages to kill a few of them, and eventually escapes the island with the other survivors.
In the film's introduction, when a worker is attacked by a Velociraptor that the park staff are transporting, Muldoon gives the order to kill it. He notes that the raptors have tested the perimeter fence in different places, probing for an opening, and comments that the animals "show extreme intelligence. Even problem-solving intelligence." He remains in the control room with Hammond and Arnold, commenting on the many safety and security failures of the park. After the power failure, he drives Ellie to the Tyrannosaurus escape site where they rescue Malcolm. In the jungle during an attempt to restore power, Muldoon prepares to shoot a Velociraptor in the distance. Instead, a second raptor ambushes him from the side while he is focused on the first raptor. Muldoon remarks "Clever girl" as he discovers the trap and is killed by the second raptor.

Dennis Nedry

Dennis Nedry is one of the main human antagonists in the novel and film. In the novel, he is described as an obese and messy computer scientist. Nedry works for Hammond as the system's programmer and is in charge of networking Jurassic Park's computers. Although he was not given any details about InGen's operation, Nedry was expected to fix numerous bugs and issues without understanding the ultimate goal. After InGen blackmails him to make changes to the system without further payment, he makes a deal with Dodgson of Biosyn to steal embryos of the park's 15 dinosaur species. He is promised $50,000 for each species he delivers, and an additional $50,000 for each embryo that proves viable, for a maximum payment of $1.5 million. Dodgson provides Nedry with an embryo carrier/cooler disguised as a can of shaving cream. In order to carry out the theft, he shuts down the park's security systems, including several electric fences surrounding select dinosaur paddocks. He plans to steal embryos from a secure lab, drive across the park to hand them off to a Biosyn agent waiting at the dock, then return to the control room and reactivate the security systems before his absence becomes suspicious. On his way to deliver the embryos, a tropical storm causes him to miss crucial road signs, and he becomes lost in the jungle and is subsequently blinded and killed by a venomous Dilophosaurus. In the novel, his body is later found by Muldoon and Gennaro. Although Nedry's pride in his knowledge of complex computer systems makes him feel more important than the other workers, Lex /Tim is later able to navigate the system in order to restore power to the Visitor Center.
Nedry's role in the film is generally the same as in the novel, with some minor changes to his fate. He crashes his Jeep through a guardrail and runs off the road, then takes shelter in the vehicle after a Dilophosaurus spits venom in his eyes, dropping the shaving cream container as he does so. The animal rears up in the passenger seat, after which the camera cuts to a long shot of the Jeep shaking to the sound of Nedry's screams. His body and the container are not found by anyone, the latter rolling down a hill and becoming buried in mud. In the second film, Nedry's death is not mentioned, either in the general release nor in a deleted scene in which Ludlow mentions the names of deceased victims to InGen's board of directors. However, according to the Dinosaur Protection Group promotional website for Jurassic World: Fallen Kingdom, human remains were found in a cleanup operation a year after Nedry's death and identified as those of an employee who "initiated a premeditated attack on the park system", but were deliberately concealed by InGen until events were exposed years later.
In , which is set immediately after the events of the first film, Nedry's body is discovered by the video game characters of Nima Cruz and Miles Chadwick, the latter of whom was briefly featured in the film calling Nedry from the docks.

Dr. Henry Wu

Dr. Henry Wu is a character in the first novel and film, and later returns in the fourth and fifth films, Jurassic World and Jurassic World: Fallen Kingdom. Dr. Wu is the biotechnologist and chief geneticist in Jurassic Park and head of the team that created the dinosaurs. In the novel, he is a former child prodigy who was personally recruited by Hammond after finishing his doctorate. Although he is the instrumental figure behind the procedures used to bring the dinosaurs to life, he demonstrates little concern for the animals, and is unable to remember exactly what species he has created. He proposes genetically altering the dinosaurs to make them more manageable, noting that many of their early assumptions about the behavior and biology of the animals had been wrong, but did not get Hammond's approval. When he is later presented with the fact that the dinosaurs have been breeding, essentially proving that he had failed to engineer them properly, he mistook it as a "tremendous validation of his work". In the novel, he is killed during the assault on the Visitor Center when a Velociraptor jumps onto him from the center's roof and guts him. He is mentioned indirectly in the second novel when Malcolm discovers old InGen documents addressed to Dr. Henry Wu scattered throughout the abandoned manufacturing plant on Isla Sorna.
Wu has a greatly reduced role in the first film, merely giving a tour of the research facility. He leaves the island on the last boat to the mainland before the tropical storm and the power failure.
Wong returned to portray Wu in the 2015 film Jurassic World. In 2014, a viral marketing website for the fictional Masrani Global Corporation was launched to promote Jurassic World. According to the website, Dr. Wu continued his work on DNA and created the Wu flower using the DNA of different plants. Masrani Global's CEO Simon Masrani took over InGen and promoted Wu. In November 2014, the website stated that InGen facility "Martel" opened in Siberia to extract Pleistocene-dated organic materials from glacial ice, and that Wu believed this would expand InGen's genome library.
In Jurassic World, Dr. Wu is first seen with Claire Dearing trying to attract investors with the genetically modified hybrid Indominus rex, using the genetics of the Tyrannosaurus rex, pit viper, tree frog, cuttlefish, Velociraptor, Carnotaurus, Therizinosaur, Gigantosaurus, and other animals. After the Indominus escapes, Wu declines to specify the animal's genetic make-up, stating that he is not at liberty to reveal such information. When Masrani informs Wu of the Indominuss ability to camouflage and to regulate its body temperature, Wu reveals that the animal includes tree frog and cuttlefish DNA, allowing it to do such things. Outraged, Masrani orders Wu to shut down his operations, but Wu reminds him that the geneticists have always used the DNA of other animals to fill gaps in the dinosaurs' genomes. Wu further states that many of the dinosaurs would look "quite different" if their genetic codes were pure. Wu is later revealed to have been secretly working with InGen Security head [|Vic Hoskins] to create the Indominus rex as a weapon. Hoskins has Wu and his InGen Security team flown from the island to an unknown location along with dinosaur embryos, thus protecting his research.
Wong reprised the role in the 2018 film ', in which Wu is working for Eli Mills. In the film, Wu has created the Indoraptor by inserting additional Velociraptor DNA into his earlier Indominus rex hybrid. The Indoraptor is auctioned despite Wu's protests that it is an early prototype. Later in the film, Wu plans to get blood from Blue the Velociraptor to make an improved Indoraptor. However, he is told by paleo-veterinarian [|Zia Rodriguez] that she had transfused blood from a T. rex to save the raptor's life, making Blue's blood impure. [|Franklin Webb] then drugs Wu to subdue him and Wu is dragged away by one of Mills's mercenaries.
BD Wong is expected to reprise the role in , scheduled for release in 2021.

Ed Regis

Ed Regis is a publicist for InGen and the head of public relations for Jurassic Park. Regis is often given odd jobs by Hammond that are outside his area of expertise, such as escorting a wounded worker to a Costa Rican hospital, and acting as a babysitter for Lex and Tim during their visit to the park. Despite being overconfident about the park and almost negligent about the accidents that have been occurring, fear quickly overtakes him as things begin to go wrong, since he had already witnessed the brutality of dinosaur attacks. When the Tyrannosaurus breaks free of its pen, he abandons the tour vehicle, leaving Tim and Lex behind. After hiding between some boulders, he tries to make his way back to the cars, but is killed by a juvenile Tyrannosaurus. His severed leg is later discovered by Gennaro and Muldoon as they investigate the attack.
Ed Regis's character is written out of the film, although certain aspects of his character such as his nervousness and cowardice are given to the film's version of Donald Gennaro. Gennaro's death sequence during the T. rex attack in the film is reminiscent of Regis's death.

Mr. DNA

Mr. DNA is a cartoon character that resembles an anthropomorphic DNA helix with a face and arms who was exclusive to the film franchise. He is the mascot for Jurassic Park and Jurassic World. Most of his lines and explanations are said by Henry Wu in the novel during a tour of the genetics lab, some of which is still given to the cameo Wu makes in the original film.
In Jurassic Park, Mr. DNA appears in videos to help visitors understand the processes involved in the creation of the dinosaurs at Jurassic Park. A video starring him and InGen's founder John Hammond is played in a theater located in the park's Visitor Center before a tour. He became iconic with the franchise, even though he was given a small role in the original film. Animator Bob Kurtz developed its animation sequence.
In the Super NES version of the Jurassic Park video game, Mr. DNA appears onscreen and offers the player dinosaur trivia. In the 2011 video game, , Mr. DNA is visible on the maintenance board of Jurassic Park's geothermal power plant and on a board indicating how tall a person must be to ride the upcoming Bone Shaker roller coaster.
In Jurassic World, Mr. DNA was used by the Masrani Global Corporation for their new dinosaur park, Jurassic World. He remained the same as his original counterpart, but two variations of him exist: one with only blue and white representing the colors of Jurassic World's logo and the other being red and white. Visitors encounter him in the Innovation Center where he explains the basics of genetics and how the dinosaurs were recreated.
In the 2015 video game Lego Jurassic World, Mr. DNA is a playable character and appears throughout the game to give hints to the player on how to progress through the levels. Mr. DNA is also a character players can collect. As with the original Jurassic Park video game, he also offers the player dinosaur trivia. He is aware of InGen's political dealings and will inform the player of them, yet always presents such in a positive way.

Appearing in ''The Lost World''

These characters first appear either in the novel, The Lost World, or in the film adaptation, .

Dr. Sarah Harding

In the novel, Dr. Sarah Harding is an ethologist who specializes in African predators. She is intelligent, feisty and rugged, and employs common sense and practicality in dangerous situations, putting the safety of her colleagues first. Her calm personality permits her to quickly take command of the group and devise ways for them to survive and escape the island. She and Ian Malcolm were in a relationship for a period, and at one point she claimed she was in love with him. The relationship did not work out, although they remained close friends. She is idolized by [|Kelly Curtis] who sees her as tough and smart. In the novel, she mentions that her father was a veterinarian and bird specialist at the San Diego Zoo, implying that Dr. Harding is her father.
In the movie, Sarah Harding's character is merged with that of Richard Levine's. She is intelligent and feisty as well as kind and jolly, but impulsive and too eager to interact with the animals, often placing herself and others in danger. As well, her character is a behavioral paleontologist, a 'paleo-ethologist', rather than just an animal behaviorist, who specializes in dinosaur parenting behavior. Her relationship with Ian Malcolm is far more in-depth, as they'd gotten together after the events of the first film and they remain together for the duration of the film. She is shown to be compassionate towards the dinosaurs, in such situations as petting a baby Stegosaurus, freeing dinosaurs from InGen, healing a baby T. rexs leg, and shooting the male T. rex with a tranquilizer dart to protect him from the military and police forces in San Diego's port.

Kelly Curtis

Kelly Curtis is a close friend of [|Arby] in the novel, and is Ian Malcolm's daughter in the film. In the novel, Kelly is a 13-year-old girl who is fascinated by science and idolizes Dr. Sarah Harding. Richard Levine, aware that he is being followed by Ed James, hires Kelly and Arby as his assistants to run errands for him ahead of his expedition to Isla Sorna. When Kelly learned that Sarah would be on the trip, she decided to sneak aboard a trailer being transported to the island. While on the island, Kelly manages to overpower a Velociraptor by hitting one with a broken pipe and shooting one with an air rifle. In the film, Kelly was abandoned by her mother after her parents' separation. She is skilled in gymnastics, which she uses to rescue her father from a Velociraptor. The film adaptation portrays her as African American, a trait shared by Arby, who does not appear in the film.

[|Nick] Van Owen

Nick Van Owen is a video documentarian and member of Malcolm's expedition to Isla Sorna. He is an experienced field photographer who has covered wildlife and combat situations, and began volunteering with Greenpeace to meet women. His experience with Greenpeace later spurs him to act in defense of the dinosaurs. He is the only member of his team to be warned by Hammond about InGen's expedition, and sneaks into their camp to release captured animals and disrupt their harvesting operation. He also rescues the infant T. rex from [|Roland] Tembo, leading to a confrontation with its parents which strands both teams on the island. As the teams merge and form an escape plan, Nick easily gains the tacit respect of the rugged InGen men, as in one scene he is shown to effortlessly motivate the men while Peter Ludlow fails. His activist nature conflicts with the hunter style of Roland, and he covertly switches the latter's ammunition to ensure the T. rex adults will not be killed. When the group reaches the island's InGen compound, Nick uses the radio to call for rescue. He leaves on the first evacuation helicopter departing Isla Sorna.
David Koepp, the film's writer, chose the surname Van Owen as a reference to one of his favorite songs, "Roland the Headless Thompson Gunner", by Warren Zevon.

Richard Levine

Richard Levine is one of the most brilliant and wealthy paleontologists in the Jurassic Park universe. Dr. Marty Guitierrez seems to be his only real friend, although he eventually forms a delicate relationship with Ian Malcolm. Levine's egotism and spontaneous personality prove to be a source of constant irritation to the rest of his colleagues, mainly Malcolm. After being arrested for speeding, Levine is ordered by a judge to teach a junior high school class, where he meets students Arby Benton and Kelly Curtis. Aware that he is being followed by Ed James, Levine hires Arby and Kelly as his assistants to run errands for him ahead of the expedition. Unlike his colleagues, the two children look up to Levine, leading him to develop a paternal attitude towards them.
Levine originally intended to travel to Isla Sorna as part of Malcolm's team, but goes there on his own before the Costa Rican government has a chance to destroy the island. When the rest of his team arrives, they find themselves constantly running after him when he decides to continue his research regardless of what is happening around him. Although he is bitten twice by Procompsognathus, he ultimately escapes the island without major harm. While not appearing in the film, some of his aspects were merged with the character Sarah Harding.

Jack "Doc" Thorne

Jack "Doc" Thorne is a former university professor and materials engineer who specializes in building field equipment, vehicles, and weaponry for scientists. Thorne is also the boss of [|Eddie Carr]. He exhibits an eclectic mix of character traits, relying on both practical expertise and Eastern philosophy, claiming that one needs to know philosophy and history to succeed in engineering. His company, Mobile Field Systems, is hired to outfit Richard Levine's expedition to Isla Sorna. Thorne's contribution to Levine's mission includes a large research trailer, nicknamed "The Challenger", an electric SUV, a motor bike, a pair of air rifles, and a modified satellite phone. When Levine goes missing on the island, Thorne heads to Isla Sorna with Ian Malcolm and Eddie Carr to retrieve him. Thorne saves his friends multiple times, and survives his time on the island.
Thorne is not in the film, although parts of his character are integrated into the roles of Eddie Carr and Roland Tembo.

Eddie Carr

Eddie Carr is the group's field equipment expert. He is added to the team because the vehicles he designed have not been field-tested. Eddie is frightened by Isla Sorna and wants nothing more than to retrieve Richard Levine and get off the island as soon as possible. He has a slightly antagonistic relationship with Ian Malcolm, who does not like that Carr's world is so heavily influenced by unreliable electronics. He is eventually killed by a pack of raptors while fighting them off with an iron pipe. In the film, while he is attempting to rescue Ian, Sarah, and Nick, he is killed by the two adult T. rex before they push the trailers off the cliff. In the film, his relationship with Malcolm is apparently positive, for Malcolm leaves him to take care of his daughter. When he is eaten, Malcolm demands that he be given respect for trying to rescue them.
In the novel, he is described as a compact and strong 25-year-old who prefers the city. In the film, he has black hair, is balding, and is at least ten years older than the description in the novel, taking on some characteristics of [|Jack Thorne].

R. B. "Arby" Benton

R. B. "Arby" Benton is an 11-year-old African-American boy who is friends with Kelly. He tends to be quiet and shy, but is very intelligent and good with computers. He skipped two school grades and is in seventh grade with Kelly. When Kelly expressed interest in stowing away in the Challenger trailer with him, it was Arby who came up with a plan on how to do so. He does not appear in the film adaptation, although Kelly is portrayed in the film as an African American.

Howard King

Howard King is an assistant to Lewis Dodgson. Once a successful biologist employed by Biosyn, he lost credibility when his research on blood-coagulation factors failed. Dodgson hired King as his assistant in the reverse-engineering department. He is divorced and has one child, who he sees only on weekends. He accompanies Dodgson to the island, and eventually begins to disagree with Dodgson's dark desires. They are separated after being chased by tyrannosaurs. Eventually, King flees from a pack of raptors in a field of tall grass. A raptor knocks him over and inserts its claws into his back, before biting into his neck and killing him.

George Baselton

George Baselton is a biology professor and assistant to Lewis Dodgson. As a well known authority and pundit, he is retained by Biosyn and Dodgson to spin any bad press that may arise. When he and Dodgson are trying to steal Tyrannosaurus eggs, the sonic device Dodgson is using to keep the parent Tyrannosaurs at bay becomes unplugged. Both men stand absolutely still, falsely believing that the dinosaur's vision is based on movement. The Tyrannosaurus subsequently kills him.

Diego

Diego is Levine's guide on Isla Sorna. He is a young and enthusiastic Costa Rican who went to the island several times as a boy and knows it better than anyone else. He does not believe that the dinosaurs are there. Even when Levine warns him to be quiet, he simply says that they have nothing to fear. He seems to annoy Levine many times, not only with his insistence that only birds live on the island, but also by disobeying his orders to refrain from using items like cigarettes. Diego is killed when he is ambushed by a Carnotaurus while he and Levine watch a Mussaurus in total awe.

Peter Ludlow

Peter Ludlow is the anti-villainous main antagonist of the second film, John Hammond's nephew, and the newly elected of InGen. He attained this position after convincing InGen's board of directors to oust Hammond following an accident on Isla Sorna, in which a group of Compsognathus attacked a girl who was visiting the island with her family. Ludlow is also directly responsible for tarnishing Ian Malcolm's reputation, through outright bribes to Costa Rican officials and misinformation to the press, when Malcolm tries to expose InGen's cover-up of the Jurassic Park incident. His character, based on Lewis Dodgson and the first novel's John Hammond, is ruthless, selfish, greedy and condescending toward those who work for him or those he dislikes. As a result, he is not very well respected by the members of his team who instead choose to follow Roland Tembo or Nick Van Owen. In an attempt to revitalize Hammond's original Jurassic Park attraction in San Diego, Ludlow assembles an InGen team to recover Isla Sorna's dinosaurs and move them to the original park. But Ludlow only manages to bring back the male T. rex and its infant, with disastrous results leading to his own demise, as the adult T. rex wreaks havoc on San Diego.
Ludlow's death mirrors that of Lewis Dodgson. While trying to recapture the infant in the hold of an InGen cargo ship, he is confronted and captured by the adult and then fed to the infant.

Roland Tembo

Roland Tembo is a hunter hired by InGen to lead the expedition. Although he is hired by InGen, his primary motivation for going to Isla Sorna with his hunting partner and friend Ajay Sidhu is to hunt the ultimate trophy, a male Tyrannosaurus. Although he gets his prize in the end, he is upset by the death of Ajay. When Ludlow offers him a job at the planned Jurassic Park attraction in San Diego, he declines by saying; "I believe I've spent enough time in the company of death." Without hesitation, Roland leaves the island by helicopter.
As with Van Owen, Koepp chose the name Roland as a reference to one of his favorite songs, "Roland the Headless Thompson Gunner", by Warren Zevon.

Dieter Stark

Dieter Stark is Roland's second-in-command during the InGen team's expedition on Isla Sorna. Dieter expresses dislike for Nick and gets into a scuffle with him following Nick's release of the InGen team's captured dinosaurs, who destroyed the team's base camp and communications equipment. After getting lost while trying to find a spot in the forest to urinate, he is attacked and killed by a group of Compsognathus; this is confirmed after Roland and Ajay find him at night. Although his surname is not mentioned in the film itself, it is listed in the credits.

Ajay Sidhu

Ajay Sidhu is Roland Tembo's friend and hunting partner. He accompanies Roland during his attempt to capture the T. rex. Fleeing from the T. rex, he warns the InGen team to avoid an elephant grass field, but they disobey this warning, after which he follows them in. The group is eventually killed by Velociraptors. Ajay's death is not shown on screen, but Roland later confirms it, by stating that Ajay "didn't make it".

Dr. Robert Burke

Dr. Robert Burke is the InGen team's paleontologist who provides several pieces of incorrect information. During a conversation with Malcolm, Sarah Harding states, "Robert Burke said that the T. rex was a rogue that would abandon its young at the earliest opportunity." Burke's theory is disproved later in the film when adult Tyrannosaurs attack the trailer in which their infant is being held. Burke and others hide behind a waterfall when they are pursued by a Tyrannosaurus, but he is startled when a milk snake slithers down into his shirt. Failing to identify that the reptile isn't venomous, he panics and is subsequently caught and eaten by the female T. rex.

Carter

Carter is a member of the InGen team. Because of headphones, he fails to hear Dieter's cries for help as he is attacked by a pack of Compsognathus. Carter is killed when the female T. rex steps on him while he flees with the rest of the InGen team.

Ed James

Ed James is a private investigator hired by Lewis Dodgson to get information about Richard Levine and the survivors of the Isla Nublar incident. After placing a bug in Levine's apartment, he learns the location of Isla Sorna, which he then reports to Dodgson. He does not accompany either team to Isla Sorna.

Appearing in ''Jurassic Park III''

These characters only appear in the third film, Jurassic Park III ; there was no third novel.

Paul Kirby

Paul Kirby is a hardware store owner whose 12-year-old son Eric goes missing near Isla Sorna. Paul and his ex-wife Amanda pose as a wealthy couple, promising to fund Grant's dig site to lure Grant into accompanying an aerial tour of the island. They fly there with a mercenary team, land against Grant's orders, and become stranded following an attack from a Spinosaurus. The Kirbys reveal the truth to Grant, that the Costa Rican and U.S. governments had declined to help search for Eric, and that they tricked Grant on the advice of [|Udesky], a member of the mercenary team who stated that they needed someone who had been on the island before. When the group is attacked by the Spinosaurus on a river, Paul uses himself as bait so the others can escape. This allows Grant an opportunity to divert the Spinosaurus using a flare gun. Paul survives the incident and is rescued from the island with the others.

Amanda Kirby

Amanda Kirby is Paul's ex-wife who accompanies the search party to "Site B" to help look for their missing son, Eric, and her boyfriend, Ben. Through most of the film, Amanda ignores Grant's warning that loud shouting attracts carnivores. Grant locates Eric, and Amanda eventually reconciles with Paul. When the group is confronted by the raptor pack, Amanda, the lone female in the group, is ordered by Grant to return the stolen eggs to the raptors. She is rescued from the island, along with Paul, Eric, Grant, and his assistant, Billy.

Billy Brennan

Billy Brennan is a young and overenthusiastic graduate student at Grant's dig site. He accompanies Grant to Isla Sorna where they are stranded with the Kirbys. He later collects Velociraptor eggs, intending to sell them to help fund Grant's dig site, but causing Velociraptors to stalk the group. Grant is angry when he learns that Billy took the eggs. Billy redeems himself by saving Eric Kirby from Pteranodons. He survives but becomes separated from the others and is presumed dead. He is rescued by the military, and reunited with Grant on a helicopter.

Eric Kirby

Eric Kirby is the 12-year-old son of Paul and Amanda who is stranded for nearly eight weeks on "Site B", and must fend for himself. He finds a way to collect T. rex urine and a raptor claw. Dr. Grant says he had a fossil one, from the first film, but Eric replies that his is a new one. After being saved from Velociraptors, Grant reunites him with his parents. After escaping from a Spinosaurus, a flock of Pteranodons and Velociraptors, he leaves the island with his parents, Grant, and Billy.
A series of books written by Scott Ciencin follow Eric's time on Isla Sorna before Grant and the others arrive. These books are ', ', and .

Udesky

Mr. Udesky is one of the mercenaries hired by the Kirbys, who describes himself as a booking agent taking the place of another man who became ill. He is meek but sardonic, and is balding with a short mustache. Udesky survives the Spinosauruss attack on the plane but is separated from the others during a raptor attack. A raptor stabs Udesky's back with its toe claw, immobilizing him in an attempt to lure the other humans out to help him. When this does not work, a Velociraptor kills Udesky by snapping his neck.

Cooper

Cooper is one of the mercenaries hired by the Kirbys. Shortly after landing on Isla Sorna, Cooper and the other mercenaries encounter a Spinosaurus and flee back to the plane. With Cooper behind in the jungle, Udesky demands the others to get back on the plane, stating: "Cooper's a professional; he can handle himself." The plane begins to take off, and Cooper emerges onto the runway and tries to get the plane to stop for him, but pilot Nash refuses. The Spinosaurus snatches Cooper in its mouth, and the plane hits the animal and crashes through the forest.

Nash

Nash is the Kirbys' mercenary pilot who abandons Cooper and is subsequently attacked by a Spinosaurus, which drags him out of the plane's wreckage by the legs. As Nash tries to crawl through the jungle to escape, the Spinosaurus pins him to the ground with its foot, and devours him. He is carrying a satellite phone given to him by Paul shortly before he is eaten. Later, when the others hear the phone ringing from within the dinosaur's abdomen, they know the Spinosaurus is nearby. The phone is later recovered from a pile of Spinosaurus dung.

Mark

Mark is Ellie's husband. He works for the U.S. State Department, and specializes in international relations and treaty law. They have two young children, including [|Charlie].

Ben Hildebrand

Ben Hildebrand is Amanda's boyfriend. He takes Eric parasailing near Isla Sorna. When the boat crew is killed, Ben saves Eric and himself by disconnecting the para-sail from the vessel and gliding onto the island. However, they crash-land in a tree. Although his cause of death is left unexplained, his decomposing corpse is found tangled in his parachute.

Enrique Cardoso

Enrique Cardoso is the operator of the illegal para-sailing service called "Dino-Soar" which brings visitors to sight-see along the coast of Isla Sorna. He is hired by Ben Hildebrand and Eric Kirby to take them to the island; however, Enrique and his boat driver are killed offscreen when they enter a fog bank, causing the vessel to crash and the tourists to become stranded on "Site B". His cause of death is not explained in the film.

Charlie

Charlie is the young son of Ellie and Mark, who calls Grant "The Dinosaur Man". Grant phones Ellie while being attacked by the Spinosaurus, but it is Charlie who answers the phone. Grant tells Charlie to take the phone to Ellie, but he is soon distracted by an episode of Barney & Friends.

Appearing in ''Jurassic World''

These characters first appear in the fourth film, Jurassic World.

Owen Grady

Owen Grady is one of the main protagonists of Jurassic World and its sequel Jurassic World: Fallen Kingdom. Pratt and Jurassic World director Colin Trevorrow described Owen as a combination of Alan Grant and Ian Malcolm, with Pratt stating, "He's got a little bit of the Goldblum cynicism but also the Sam Neill excitement at the wonder of the biology of it". Owen is an on-site animal behaviorist at Jurassic World who was formerly in U.S. Navy. He has romantic feelings for Claire Dearing, though they agreed not to pursue a relationship due to their conflicting personalities. Owen opposes genetically modifying dinosaurs to increase the appeal factor for audiences.
Owen had been rearing and training four Velociraptors since they hatched so that they would imprint on him, and conducts behavioural research on them. He objects to Vic Hoskins's proposal to use raptors as military weapons, explaining that his relationship with the four raptors is a personal one and that they only respond to him under controlled conditions. This is demonstrated when he risks his life saving an employee who falls into the raptor paddock when trying to capture a pig that had escaped into the enclosure. Later, Owen criticizes the Indominus rexs paddock, which provides no social interaction. It appears that the Indominus rex has escaped but Owen discovers it has camouflaged itself and masked its heat signature; two staff are killed and Owen barely survives the ambush. When the Indominus rex escapes, Owen demands the dangerous and bloodthirsty animal be hunted and killed.
Owen helps Claire search for her nephews, Zach and Gray, who are exploring the park on their own, and is shocked by how little Claire knows about them. They trail the boys, eventually returning to the main resort where escaped pterosaurs are attacking visitors. Owen shoots several, and Claire saves him from a Dimorphodon attack. They reconnect romantically with a kiss, then are reunited with Zach and Gray, who idolize Owen for his skill and bravery. Owen learns that Hoskins, backed by his InGen team, has taken charge of the park and plans to use the raptors to track the Indominus. Owen reluctantly agrees to the plan on the condition that he commands the operation. The plan works initially but backfires when the raptors begin communicating with the Indominus, which usurps Owen as the raptor pack's alpha. He is able to rekindle his bond with Charlie, but a soldier kills the raptor with a missile launcher.
Later, Owen, Claire, Zach, and Gray arrive at the laboratory and discover that InGen had cleared it, taking dinosaur embryos with them. Hoskins reveals his plan to use the Indominus rex as a weapon. Delta appears and kills Hoskins while Owen, Claire and the boys escape. Outside, they are confronted by the other raptors. Owen is able to re-establish his bond with the raptors who attack the Indominus, aided by Owen, but two are killed. Claire releases the Tyrannosaurus from its paddock and lures it into a fight with the Indominus. Blue also attacks the Indominus, which is ultimately forced toward the park lagoon where the Mosasaurus grabs it and drags it underwater. Owen sees Blue one last time before Blue runs off. Owen and Claire decide that they will remain together.
Pratt reprised his role as Owen Grady in 2018's '. After the Jurassic World incident, he and Claire have ended their relationship and he is building a cabin. He joins Claire and her Dinosaur Protection Group, to try to save the Isla Nublar dinosaurs from a volcanic eruption, mainly as a means to save Blue. But he and the others discover that they have been double-crossed by [|Ken Wheatley] and his contractor Eli Mills, the assistant of Benjamin Lockwood. Owen, along with Claire and the others, discovers that Mills is illegally auctioning the dinosaurs to the highest bidder at the Lockwood Estate in northern California. With help from Lockwood's nine-year-old granddaughter, Maisie, Owen learns that Dr. Wu created the Indoraptor, made from a Velociraptor and the bone sample of the Indominus rex, and Wu wants Blue's DNA to create another Indoraptor prototype that is as obedient as her. Disrupting the auction, Owen knocks out most of Mills's mercenaries in a physical fight to stop the Indoraptor from being shipped to its new owner. Protecting Claire and Maisie from the Indoraptor and the mercenaries, Owen, with help from Claire and Blue, is able to kill the Indoraptor by causing it to become impaled on the fossilized horn of a ceratopsian skull. When a hydrogen cyanide leak threatens captive dinosaurs that were not sold in the auction, Owen advises Claire against releasing them, but Maisie lets them loose. Owen is later shown driving an old station wagon, accompanied by Claire and Maisie. Since the incident, Owen and Claire have reconciled their relationship. While not stated in the film, writer Colin Trevorrow said that Owen and Claire become adoptive parents to Maisie.
Chris Pratt will reprise his role as Owen Grady in the sixth film ', scheduled for release in 2021.

Claire Dearing

Claire Dearing is one of the main protagonists of Jurassic World and its sequel Jurassic World: Fallen Kingdom. She is the workaholic operations manager at dinosaur theme-park Jurassic World. Claire is aunt to Zach and Gray Mitchell. She had a single date with Owen Grady before the events of the film, but they did not pursue a relationship due to their conflicting personalities and lifestyles.
Claire is first seen attempting to recruit corporate sponsors who want more exciting dinosaurs. She shows them Dr. Wu's new genetically-modified hybrid dinosaur, the Indominus rex, which she authorized the geneticist to create under park owner Simon Masrani's orders. When the Indominus escapes, Claire dismisses Owen's claims that it is a highly intelligent animal and must be killed, and orders its recapture. When this attempt fails and results in casualties, she rejects Owen's order to evacuate the entire park and instead closes park sectors and attempts to relocate the customers to the center of the resort. She soon realizes that her nephews are missing, and enlists Owen's help in finding them.
Despite Owen's objections, Claire accompanies him to search for the Indominus and her nephews. While Owen comforts a dying Apatosaurus that had been attacked by the Indominus, Claire emotionally bonds with it, altering her view of the park's dinosaurs as "assets". She later comes to see that the Indominus should be killed. Another hunting attempt ends disastrously, resulting in the Indominus breaking into the park's aviary, freeing all the pterosaurs with the helicopter crashing and killing Masrani. As the escaped pterosaurs attack the customers, Owen and several park hunters attempt to shoot them. Claire rescues Owen from a Dimorphodon attack, and they kiss. Their moment is cut short by Claire's reunion with Zach and Gray.
Vic Hoskins and his InGen team take control of the park after Masrani is killed, and Claire accuses Hoskins of hoping for such a disaster. Later, to stop the Indominus, Claire lures the park's Tyrannosaurus into a fight with it. The Indominus is ultimately killed, and the survivors are evacuated from the island, where Claire and her sister Karen reunite. Claire and Owen decide that they will stay together.
In ', Claire and Owen have ended their relationship and she is leading the Dinosaur Protection Group, an organization dedicated to save the Isla Nublar dinosaurs from a volcanic eruption. Her experience from the Jurassic World incident changes her; she is both compassionate toward the dinosaurs and hardened by her ordeal. She also meets Maisie Lockwood, the nine-year-old alleged granddaughter of Benjamin Lockwood, and bonds with the girl. Claire, her team, and Owen later discover that Lockwood's aide, Eli Mills, is illegally auctioning the dinosaurs, and they work to stop him from shipping Wu's deadlier hybrid prototype, the Indoraptor. She and Owen also learn that Maisie is a clone of Lockwood's deceased daughter. After Claire and Owen succeed in killing the Indoraptor, they are shown driving in a station wagon with Maisie. Since the incident, Claire and Owen reconcile their relationship. Writer Colin Trevorrow stated that Owen and Claire become adoptive parents to Maisie.
Bryce Dallas Howard will reprise her role as Claire Dearing in the sixth film ', scheduled for release in 2021.

Vic Hoskins

Vic Hoskins is the main human antagonist of the fourth film. He is the head of the security division of InGen.
In 2014, a viral marketing website for the fictional Masrani Global Corporation was launched to promote Jurassic World. According to the website, Hoskins attained the head position at InGen Security after overseeing the elimination of Pteranodons that escaped to Canada following the events of Jurassic Park III. Over time, he redeveloped and improved InGen Security.
Prior to events in Jurassic World, Hoskins had been involved in a two-year research program at the theme park meant to test the Velociraptors intelligence. After observing the raptors obey Owen's commands, Hoskins sought to use them as military animals and put them through a field test. Owen objects, and Masrani later rejects Hoskins's idea to use raptors to hunt the Indominus. When Masrani is killed, Hoskins takes command and puts his raptor plan into effect to kill the Indominus, and Owen reluctantly agrees to take part. When it fails, Hoskins and the InGen team prioritize the evacuation of the lab, saving the dinosaur embryos and transporting them, along with Dr. Wu, to an unspecified location.
Hoskins reveals to Owen and Claire that he intends to create miniature versions of the Indominus as weapons to keep InGen Security viable. Before he can leave, the raptor Delta appears and corners him. Hoskins attempts to mimic Owen's hand signals to assuage Delta; although it works briefly, the raptor fatally mauls him.
Earlier in the movie, all raptors express animosity toward him, and Delta had stared at Hoskins in a menacing way while he inspected her. [|Barry] explained that she only did that when she was hungry. Before this, when he inspected her on a previous occasion, she hissed and growled at him, taking an immediate dislike to him.

Gray Mitchell

Gray Mitchell is Claire's nephew, Zach's younger brother, and a visitor to Jurassic World. He is known for his enthusiastic behavior and his obsession with the park, to the annoyance of Zach. He is also concerned and upset by his parents' impending divorce. Zach has them abandon Claire's assistant Zara to explore the park on their own, and they enter a restricted area where they encounter the Indominus. Gray and Zach escape by jumping off a waterfall, and subsequently find the decaying remains of the original Jurassic Park Visitor Center. Working together, the brothers restart an old Jeep and drive back to the resort, where they find Claire and Owen Grady. Later, during the final confrontation between Owen's raptors and the Indominus, Gray convinces Claire to have Lowery release the Tyrannosaurus by claiming that they need "more teeth" to defeat the Indominus. Gray and his brother survive their ordeal at Jurassic World, and are reunited with their parents at the end of the film.

Zach Mitchell

Zach Mitchell is Claire's nephew, Gray's older brother, and a visitor to Jurassic World. When the brothers first arrive, Zach is annoyed and embarrassed by Gray's enthusiasm for the dinosaur exhibits, and mostly ignores him. When Gray becomes upset over their parents' impending divorce, Zach remains unsympathetic, ordering his little brother to grow up. The two boys soon abandon Claire's assistant Zara to explore the park on their own, and Zach becomes a little more amused by the park. He has a girlfriend, though he constantly checks out girls at the park to the annoyance of Gray.
The boys board the gyrosphere ride, but when Claire orders all guests to return to the resort, Zach convinces Gray to stay out in the field and drives the vehicle into a restricted area, where they encounter the Indominus. When it attacks the vehicle, Zach and Gray jump off a waterfall to escape. They come upon the decaying remains of the original Jurassic Park Visitor Center, where Zach repairs an old Jeep and drives them back to the resort area, where they reunite with Claire. Zach is impressed by Owen Grady, referring to him as a "badass". He and Gray restore their bond during the crisis, and are reunited with their parents.

Barry

Barry is Owen Grady's assistant and friend, who cares for the four Velociraptors trained by Owen. When Delta stares intently at Hoskins, Barry explains to him that it is how she looks at prey when she is hungry. Like Owen, Barry argues with Hoskins that Velociraptors cannot be used as military animals. When Barry is alerted that an "asset" is out of containment, he apparently realizes it is the Indominus rex and states, "They'll never learn."
Barry drives an during the raptor hunt for the Indominus, and he is the first to realize that the raptors are communicating with it. He is later pursued by the raptor Blue and takes cover inside a hollow log for protection. She attempts to break it open, causing him to draw his pistol in defense. Unable to bring himself to shoot Blue, he instead calls out her name. This briefly rekindles their bond, but she resumes the attack. Owen is able to distract Blue, allowing Barry to escape. He later escapes the island with other survivors.
Omar Sy will reprise his role as Barry in Jurassic World: Dominion, scheduled for release in 2021.

Simon Masrani

Simon Masrani is the CEO of Masrani Global Corporation and the owner of Jurassic World. In the film, it is stated that Masrani is the eighth richest man in the world, and that John Hammond entrusted Masrani with his dying wish to open the theme park. Much like his friend, Masarani shares Hammond's joyful eccentricities and only concerned in the applications of cloned dinosaurs, making patrons' satisfaction with Jurassic World his main priority, unconcerned with the technical aspects of the engineering process.
In 2014, a viral marketing website for the fictional Masrani Global Corporation was launched to promote Jurassic World. According to the website, Masrani's father, Sanjay Masrani, started the company as a telecommunications business before eventually passing leadership to his son. The business then expanded into the oil industry and bought InGen after the death of John Hammond in 1997. The website also states that Masrani promoted Dr. Henry Wu within InGen's ranks, and that the company set up a lab in Siberia to search for Cenozoic DNA from glaciers. The website further states that in 2002, Masrani set out to construct the Jurassic World theme park, which opened on Isla Nublar in 2005.
In the film, Masrani is first seen flying a helicopter with his co-pilot, and it is stated that he will get his license in two more days. While flying, he discusses Jurassic World with park manager Claire Dearing, and makes it clear that he believes that happiness is most important for humans and dinosaurs, and tells her lessons about how one cannot be in control. When the Indominus rex escapes, Masrani orders it captured alive since he has $26 million invested in it. When most of the [|ACU team] is wiped out, Masrani confronts the hybrid's creator, Wu, who claims that he engineered it under Masrani's orders for "cooler" animals. Masrani later pilots a helicopter to track the Indominus, and he takes two ACU soldiers with him to shoot and kill the animal. The Indominus flees from the helicopter gunfire and breaks into the park's aviary, letting loose Pteranodons and Dimorphodons. Pterosaurs collide with the helicopter which crashes into the aviary, killing Masrani in an explosion.
The Masrani website states that the company experienced its worst financial crisis following the events of Jurassic World.
In Jurassic World: Fallen Kingdom, it is revealed that the Masrani Corporation paid more than 800 million in unspecified currency to settle class action lawsuits filed by the survivors of the Jurassic World disaster.

Lowery

Lowery is the park's tech-savvy operations overseer and serves as the film's comic relief.
He is a fan of the first theme park and wears a vintage Jurassic Park T-shirt. This causes Claire Dearing to scold him, considering it to be in bad taste due to the tragic events that took place there. Lowery opposes the idea of genetically modified dinosaurs, believing it goes too far and that the regular dinosaurs from Jurassic Park will always be better. He keeps a collection of toy dinosaurs on his desk, which Owen knocks off after becoming frustrated by the operations team, much to Lowery's dismay.
When Masrani is killed and Hoskins assumes command, Lowery remains on duty in the control room and warns Claire about Hoskins's plan to use the raptors to hunt the Indominus, an idea that Lowery believes is insane. After the plan fails and an evacuation is called, Lowery opts to stay and continue supporting Claire. Lowery tries to kiss his co-worker, Vivian, before she leaves, but she deflects him, saying that she has a boyfriend. Instead, he awkwardly hugs her. Claire later orders Lowery to release the Tyrannosaurus from her paddock to attack the Indominus. After the Indominus is killed, Lowery shuts down the control room and leaves with a toy sauropod.
Jake Johnson will reprise his role as Lowery in , scheduled for release in 2021.

Hamada

Hamada is commander of the Asset Containment Unit, an armed animal-control team for Jurassic World. After the Indominus rex escapes its paddock, Masrani activates the ACU. The team finds the Indominuss internal tracking device, which had been ripped out by the dinosaur. As Hamada picks it up, he notices blood dripping from above and realizes the beast can disguise itself with camouflage. The Indominus emerges from the trees and grabs him. The ACU discharges weapons, causing the Indominus to drop Hamada. Before he can crawl away, the Indominus fatally crushes him with its foot. Hamada is the first ACU team member to be killed by the Indominus.
According to the Jurassic World special edition junior novelization, Hamada was a former SWAT team leader for the Tokyo Metropolitan Police Department.

When the Pteranodons and Dimorphodons escape the aviary and attack park visitors, Zara locates the boys, but is grabbed by a Pteranodon and falls into the Mosasaurus lagoon.

Sir Benjamin Lockwood

Sir Benjamin Lockwood is John Hammond's partner in developing the technology to clone dinosaurs, though he is not mentioned in prior films or novels. Lockwood had a daughter who died in a traffic collision, and he aimed to use the technology to clone her; this led to his falling out with Hammond. His cloned daughter, Maisie, was born nine years before the events of Jurassic World: Fallen Kingdom and twelve years after Hammond's death. With the help of housekeeper Iris, Lockwood raises the clone to believe that she was his orphaned granddaughter named Maisie, and that his daughter was Maisie's late-mother.
Lockwood and Maisie reside at Lockwood Estate in northern California, located five miles from Orick. Hammond and Lockwood had built a laboratory in the subbasement of the mansion, where they extracted the first dinosaur DNA from amber, prior to starting their Jurassic Park project on Isla Nublar and Isla Sorna.

She has a passion for dinosaurs and likes to imitate them as a play activity, and expresses curiosity about her mother.
Later in the film, Maisie is fascinated by a video of Owen training his Velociraptors, including Blue. She then discovers Mills's plan to auction Isla Nublar's surviving dinosaurs, and he kills her grandfather so the auction can proceed. Maisie is distraught when she learns of his death. She grabs her grandfather's photo album, and discovers that his daughter was identical to her in appearance during childhood. With Lockwood dead, Mills becomes Maisie's guardian and dismisses Iris.
When Owen and Claire arrive, Maisie recognizes Owen from the video and Claire from a meeting she had with Lockwood.
