Former cast

Recurring experts are also sometimes referred to as "Honorary MythBusters".

Jamie Hyneman

Jamie Hyneman is a main cast member on MythBusters, along with Adam Savage. His demeanor on the show is calm, logical and no-nonsense, in stark contrast to Savage's more animated, impulsive and energetic persona. Hyneman is often exasperated by Savage's antics and he sometimes argues with him about the best approach to take. The two often have very different ideas for performing experiments and building devices. Hyneman's ideas tend to be more simplified than his co-host's, and he has a philosophy of reducing a solution to its most basic form, wherever possible. This difference has led to numerous competitions between the two presenters when testing myths, such as testing the "Goldfish Memory" myth and the "Levitation Machine" myth.
In numerous interviews, both Jamie and Adam have stated one of the reasons for the show's success is this dichotomy, and the fact that they can't stand each other, with their professional relationship being based more on mutual respect for each other's work. In a 2015 interview both said that they have completely separate lives, rarely, if ever, interacting with each other outside the show. Even while on set, they don't share meals or talk to each other off-camera. If there is an argument, they hash it out and move on, and they stated that while such arguments were a part of the early seasons, they successfully lobbied to have such situations on-camera significantly reduced.
A distinctive part of his appearance is his dark beret, white long-sleeve button-up shirt over a black T-shirt, no-rim glasses, and occasionally, mirrored sunglasses with side anti-glare guards. This, along with his walrus-style mustache and deep voice, are constant subjects for jokes by co-host Adam Savage and other team members. A sign hanging in his workshop reading "Clean Up or Die", visible in several episodes, expresses his desire to keep the shop clean and tidy.
In the "AC vs. Windows Down" myth, Hyneman revealed a food that he developed known as "the 444", a smoothie-like concoction of four fruits, four vegetables, and four grains. Despite skepticism by the rest of the crew, Hyneman described the 444's taste as "quite pleasant".

Adam Savage

Adam Savage has been involved in MythBusters since its creation. Savage's demeanour on MythBusters is animated and energetic, providing a foil to Jamie Hyneman's more reserved straight man persona.
Savage and Hyneman were the only hosts of the show for the first season of MythBusters. Starting with the second season, members of Hyneman's staff were introduced and began to appear regularly in episodes; Kari Byron, Tory Belleci and welder Scottie Chapman appeared in the second season. In the third season, Chapman was replaced by Grant Imahara, a robot builder and model maker. In an interview Savage gave during The Amaz!ng Meeting 5, he expressed an interest in proving natural selection over creationism on MythBusters.
Savage also stated that such an episode is unlikely because MythBusters has a policy against trying to disprove supernatural phenomena.

Kari Byron

Kari Byron was a co-host until 2014 with fellow co-hosts of the "Build Team," Tory Belleci and Grant Imahara. She and the others also hosted their own segments. She became involved in the show after persistently showing up at Hyneman's M5 Industries workshop in a desire to get hired by his company. She and the other Build Team members were given a more prominent role beginning with the show's second season. Not having had a long history in show business, Byron at first found it difficult to act naturally with this more visible position but gradually became more accustomed to it.
During the second half of the 2009 season, Byron was on maternity leave and was temporarily replaced by Jessi Combs. In 2010-2011, Byron had her own show, Head Rush, on the Science Channel, geared towards science education and teens.
Byron has also hosted the 2010 and 2011 editions of Large, Dangerous Rocket Ships for the Science Channel. She and Belleci made a guest appearance on the October 3, 2012 episode of the Discovery series Sons of Guns. They test fired some of the weapons in the Red Jacket shop and watched as the staff retested a myth previously busted by the Build Team: that a propane tank could explode if struck by a bullet. On August 21, 2014, it was announced that Byron, along with co-stars Grant Imahara and Tory Belleci, would be leaving MythBusters.

Tory Belleci

Tory Belleci is often considered by fellow MythBusters Kari Byron and Grant Imahara to be more of a daredevil and, as such, often performs the more dangerous stunts when testing a myth. These have included: testing the "Red Flag to a Bull" myth; testing the myth that a human's tongue will instantly stick to a frozen pole, in the "Frozen Tongue" myth; and the "Underwater Blow Dart" myth. One of his more popular stunts, shown several times on the show, was an attempt to jump over a toy wagon on a bicycle; the attempt failed, resulting in Belleci flipping forward, landing on his face and skidding across the pavement, only to immediately respond with an "I'm okay". As a result of doing these stunts, he is often involved in comical accidents while testing myths. According to the October 28, 2012 episode of MythBusters, he suffers from acrophobia.
During the "Fall Guys" myth, Belleci fell off a roof, and despite being strapped into a safety harness system, landed in an open window ledge below the drop point, and injured his leg causing substantial bleeding.
He and Byron made a guest appearance on the October 3, 2012 episode of the Discovery series Sons of Guns. They test fired some of the weapons in the Red Jacket shop and watched as the staff retested a myth previously busted by the Build Team: that a propane tank could explode if struck by a bullet.
On August 21, 2014, it was announced that Belleci, along with co-stars Byron and Imahara, would be leaving MythBusters.

Grant Imahara

Grant Imahara joined MythBusters on the invitation of friend and occasional employer Jamie Hyneman and former ILM colleague Linda Wolkovitch. He joined as the third member of the Build Team, replacing former MythBusters welder Scottie Chapman. His colleagues often jokingly referred to him as the "geek" of the Build Team. He often made the robots that are needed for the show and otherwise specialized in operating the computers and electronics for the myths. On August 21, 2014, it was announced that Grant, along with co-stars Kari Byron and Tory Belleci, would be leaving MythBusters. He died on July 13, 2020, after suffering from a brain aneurysm.

Christine Chamberlain

Christine Chamberlain was a "MythTern" who joined the MythBusters team as a result of a Discovery Channel contest and was present for the second season of MythBusters. She was mostly Jamie and Adam's assistant in myths and stayed on the show until season 3.

Scottie Chapman

Scottie Chapman is a former member of the Build Team who was called the "Mistress of Metal" for her work in welding and metal craft. Notable for her tattoos, she departed after the third season. On her MySpace blog, she revealed that she would not be back as a regular, but appeared in the "Supersize Rocket Car", as well as The Great Ice Debate myth. She also made an appearance in one episode broadcast after her departure that involved an experiment, executed over a number of months, which began when she was with the show and ended after she had left.

Jessi Combs

Jessi Combs was a cast member on the Build Team for a short time. Her arrival was announced on July 31, 2009, by the Discovery Channel when co-host Kari Byron went on maternity leave prior to giving birth to her first child. Byron left the show on the episode "Dumpster Diving" and Combs replaced her on the show. Combs was an American television personality and metal fabricator who appeared from 2005–2008 on the Spike show Xtreme 4x4 which is a part of the Powerblock on Spike. Combs was cast as a co-host of Xtreme 4x4 along with Ian Johnson after an international search which required contestants to send audition videos to Spike. Prior to appearing on Xtreme 4x4 she appeared on the TLC program Overhaulin' as a guest fabricator.
After high school Combs turned down a scholarship to attend an interior design school. In 2004 she graduated from WyoTech in the Collision & Refinishing Core Program at the top of her class. She also took the Street Rod Fabrication and Custom Fabrication and High Performance Powertrain programs.
Combs died in August 2019 in a crash of a jet-powered high-speed race car in southeastern Oregon while attempting to set a new four-wheel land speed record, which was posthumously awarded to her in June 2020 by Guinness World Records.

Jessie Nelson

Jessie Nelson, or simply Jess, was a "MythTern". She made her first appearance on MythBusters during the "Archimedes' Death Ray" episode as part of the girls' team on the small scale build-off. She appeared again in the "Whirlpool of Death" myth where she was introduced as a "MythTern". In that episode she assisted Adam with the building of scale models to test the whirlpool, and towards the end of the episode got to hold his hand as he vomited in the whirlpool tank, adding her own memorable quote to MythBusters: "Smells like pizza". She then appeared in the "Mega Movie Myths" episode, where she helped find a car for the use with the ejector seat myth; Once again, she was cited as a "MythTern". She also appeared in "Air Cylinder of Death", "Christmas Lights", "Hindenburg Mystery", "Western Myths", "Walking on Water", "Birds in a Truck", "Bifurcated Boat", mixing the non-Newtonian fluid, "Pirate Special", "Special Supersized Myths", and "Superhero Hour".

Staff

Robert Lee

Robert Lee is the narrator of the series, who shares the job of explaining experiments and facts with the hosts, often using a copious number of puns and humor. In some regions—such as the United Kingdom and Scandinavia—he is replaced by Irish and British narrators Robin Banks or Daisy Beaumont. Rufus Hound narrates the version of the show that aired on the BBC. He returns to narrate the revival MythBusters: The Search as well, and followed this with the narration for Mythbusters Junior. This makes him the longest continuous serving member of the franchise.

Eric Haven

Eric Haven is a former comic book artist who draws the blueprint drawings used to introduce each episode, as was revealed in the 2012 season's "Mailbag Special". He took over the job from the MythBusters and the former Build Team.
He has been a researcher for the program for 33 episodes from 2004 to 2005 and served as an associate producer from 2005 until 2012 for 143 episodes. Since the broadcast of Season 13, he has been credited as a producer for the show.

Guests

Helpers

Many people have come on the show to provide assistance with the myths.
In addition, several celebrity guests have been brought in to guest on the show, either for their high level of skill or knowledge in a certain area.

Buster

Buster is a Hybrid II model crash test dummy that plays an important role in many experiments by taking the place of a human subject in the more dangerous myth tests. The first and most recognized of the dummies used in the show, Buster was introduced in the beginning of the first season for the "Exploding Toilet" myth. Savage had purchased the dummy to take the place of Hyneman, and Hyneman gave it its name.
Because of the nature of the situations in which the MythBusters use him, Buster has been subjected to forces and situations that far exceed his original design parameters as an automobile crash test dummy. As a testament to the danger of the tests in which he is used—often resulting in his being broken into pieces, burnt, or otherwise mutilated—Buster has had to be extensively repaired and rebuilt over the course of the series to the point that the episode "Buster Special" was devoted to his being completely redesigned and rebuilt as "Buster 2.0". Buster was designed with quick and simple repair in mind, and boasts improved joints, with a more realistic range of movement, and easily replaceable poplar wood "bones". Poplar was chosen because its shear strength was very similar to human bone, providing an accurate gauge of how bones would react in experiments. Buster's new flesh is made of a silicone marketed for use in animatronics called Dragon Skin. Buster's original head was retained when he was rebuilt, but it had to be replaced after it was shattered during a mishap on the "Escape Slide Parachute" myth. His original face was retained to fit over his replacement head. They tested Buster 2.0 by dropping him 60 feet off a crane while inside a donated Cadillac named Earl.
The MythBusters have at times adapted Buster to fit specialized equipment or give him new functionality. For myths involving holding onto things, his hands are replaced with clamps or quick-release rigs. For myths involving falls, monitoring equipment, such as accelerometers or shock gauges, is installed on or within his body. He was also attached to a pneumatic system at one time so he could punch sharks for the "Shark Punching" myth.
Just before testing the revisited "Jet Taxi" myth, Buster spoke two lines as chosen by fans: "Adam, I am your father," followed by "I wonder if Mike Rowe is hiring," a reference to the host of Discovery's other popular show, Dirty Jobs. In October 2007, the fan site also uploaded a video spoof of Buster's life narrated by Jim Forbes of Behind the Music and starring Tory, Grant, Kari and Adam.
As Grant once noted, there are very few times when Buster is actually used for his original purpose on MythBusters.
Since his introduction on the show the cast refer to Buster as if he were an actual living person, and consider him a full member of the cast in his own right. On several myths that involved long drops or intense forces in which Buster was damaged, Adam and others expressed dismay and concern over Buster having been damaged so extensively, most notably during the "Escape Slide Parachute" myth.
On the "Viewer Special 2" episode, a new Buster was introduced. This Buster is a former crash test dummy provided by Dayton T. Brown, Inc. The new Buster was named "Buster 2.0"—not to be confused with the remodeled "Buster 1.0". The original Buster has been retired. During the James Bond special, Buster was dressed up in a tuxedo when he was used for the exploding propane myth. In most myths involving people, Buster is usually dressed in whatever clothes are relevant to the myth to give him more character and an air of faux authenticity.
In more recent episodes, the hosts of the show as well as the narrator appear to have taken up a policy of calling any human-analogue "Buster". However, this practice is very rarely, if at all, applied to dummies made out of ballistics gel or otherwise used to represent human tissue.
In the series finale, Buster is attached to a rocket sled and launched toward a concrete block wall at a speed of over Mach one, disintegrating on impact. Adam subsequently recovers some of the fragments and gives them to Jamie and the Build Team in a follow-up reunion special.

Simulaids

Simulaids are Buster's family of at least four dummies, dubbed "Randy" or "Rescue Randy", "Jane", "Suzy" or "Simulated Suzy", and an unnamed son. Rescue Randy has also been referred to as "Ted". These were added partly because Buster was becoming increasingly difficult to repair, and also because not all myths can be accurately tested with Buster due to his size, weight, and other factors. For instance, Suzy was used to test the myth that a child could go 360 degrees around a swing set. Being representative of an adult man, Buster would not have properly fit the criteria for the myth. The Simulaids were first introduced in the Killer Brace Position myth, primarily because multiple dummies were needed for testing. At least one Simulaid has been destroyed in the course of subsequent experiments.
Additionally, a dummy named Ariel was used testing whether a human in a freefall could propel a six-year-old girl off a seesaw onto a 7-story building.

Ted

Ted is an extra crash-test dummy used in the show. In addition to this, any full-size human made from ballistics gelatin is usually named Ted, from the last syllable of bus-ted, annihila-ted, exploi-ted. One instance of Ted's use was in the "Train Suction" myth, in which he played the unsuspecting commuter.

Deadblow

Deadblow, Grant Imahara's battlebot, has been used to aid the MythBusters in various ways, such as measuring vibrations in the ground to being a cat decoy. Grant temporarily renamed the robot "Blinky" and fitted it with a set of headlights to simulate an oncoming vehicle for the "Driving in the Dark" myth.

Earl

Earl was a Cadillac donated by MythBusters fan Ben Rillie who had been used in many episodes such as the "Car Capers" myth. Originally destined to be destroyed by the exploding gas tank, its failure to explode allowed Earl to be used to test myths in subsequent episodes. It was finally destroyed when it was dropped nose-down from 60 feet in the air to test the resilience of a remodeled Buster, and to satisfy the cast's promise to Ben that they would do their best to destroy the car.

Sparky

Sparky was a robot used multiple times on the show. In the "Gunpowder Keg" myth, Jamie took the motor and wheels from an electric wheelchair and fitted it with a metal hood for protection, a remote control, and a stand for a keg of gunpowder. The MythBusters drilled a hole in the keg and lit the ensuing trail of gunpowder on fire to see if the fire would travel up the falling stream of gunpowder and explode the keg. After many trials, the myth was called plausible, and Sparky survived. Sparky was used again in both the "Hot Bullets" and the "Campfire Chaos" myths to drop bullets of various caliber as well as aerosol cans into a campfire to see if they could cause serious injury or death. Sparky was not damaged, but it was determined that both bullets and bug spray could cause injury but would be unlikely to kill someone if dropped into a campfire.

Chip

Chip was the ballistic gel dummy who assisted in testing the "Phone in a Thunderstorm" myth. Chip was placed inside a miniature faux house built by the Mythbusters which was placed within a facility used to test the effects of lightning. After attaching a monitor to detect the amount of electricity running through Chip's heart, he was attached to a phone and placed in the shower with running water in separate experiements while simulated bolts of lightning struck wiring which lead directly into the house. The fuse was blown on the meter attached to Chip during each experiment, which led the team to assume the amount of electricity through Chip's heart was deadly. Thanks to Chip's sacrifice, the team concluded that the "Phone in a Thunderstorm" myth was confirmed as being potentially deadly, and the Shower in a Thunderstorm myth was deemed plausible as a dangerous or even deadly situation.

Mythdog Bo

Mythdog Bo is a small dog that appears in the 2017 revival of the show. She does not provide much help and only appears when she walks on set, and her random appearances have caused some jokes.

Buster II/Jr

Buster Jr is the version of Buster in the 2017 version of the show. He was introduced in the second episode, where they needed a criminal to block a propane chimney. They needed the replacement after the original was fired into a brick wall with a rocket.
