Cosmic Cube

The Cosmic Cube is a fictional object appearing in American comic books published by Marvel Comics. It first appeared in the Marvel Universe in Tales of Suspense #79 and was created by Stan Lee and Jack Kirby.
In the Marvel Cinematic Universe, the Cosmic Cube has been featured in multiple movies within the Infinity Saga. Initially regarded as an unlimited source of power of alien origins, it is later revealed to contain the Space Stone, one of the Infinity Stones sought by Thanos.

Publication history

The first Cosmic Cube appeared in a story in Tales of Suspense #79–81 and was created by Stan Lee and Jack Kirby. It was established as a device created by A.I.M. and capable of transforming any wish into reality, irrespective of the consequences. The Cube was also a plot device in a story that introduced the character of the Super-Adaptoid in Tales of Suspense #82–84. The Cube was also featured in a one-off story in Avengers #40 being found and briefly wielded by Namor.
The Cube reappeared in Captain America #115–120, and featured in an epic cosmic storyline that starred arch-villain Thanos in Daredevil #107 and Captain Marvel #25–33. Retrieved after Thanos' defeat, this original Cube featured in several Project Pegasus stories in Marvel Two-in-One #42–43, Marvel Two-in-One #57–58, and Marvel Team-Up Annual #5.
The creation of a second Cube was shown in Super-Villain Team-Up #16–17, but this Cube was initially powerless and did not gain any reality-altering ability until years after its creation.
A major element was added to the Cube's origin—that each is in fact an evolving sentient being—in Captain America Annual #7. The sentient Cube returned in Avengers #289–290 to end the threat of the Super-Adaptoid, and then in Fantastic Four #319. This story revealed that the villain the Molecule Man had ties to the Cube and introduced a new character.
The miniseries The Infinity War #1–6 and Infinity Crusade #1–6 established that the items actually exist in a variety of geometric forms called Cosmic Containment Units.
A third Cosmic Cube was created during the "Taking A.I.M." storyline that ran through Avengers #386–388 and Captain America #440–441. This unstable Cube has not been seen since it was sealed in a containment chamber at the conclusion of the storyline.
The previously powerless second Cosmic Cube finally gained an ability to alter reality in Captain America #445–448 but it was unstable and exploded at the end of that storyline. The second Cube's power reappeared in a storyline in Captain America #14–19 during which its power was internalized within the Red Skull, then stolen by Korvac and taken to an alternate 31st century Earth before being returned to the Red Skull on the present-day Earth, after which it was seemingly destroyed again by exposure to anti-matter energy.
Doctor Doom acquires the Cosmic Cube in the Fantastic Four miniseries The World's Greatest Comics Magazine. Doom uses a time machine to get the Cube from the ocean floor, into which it had dropped during a battle between the Red Skull and Captain America.
A Cube—together with 11 other items from Marvel and DC Comics continuity—was used once again as a plot device in the intercompany crossover series JLA/Avengers #1–4.
The Cube also shows up in Captain America. Aleksander Lukin wants the Cube and is willing to trade the Red Skull for it. The Red Skull claims he does not have it, but has spies out looking for it. Five years later, the Skull is in New York City and is in possession of it. General Lukin sent the Winter Soldier to retrieve the Cube from the Skull, and to kill him. The Skull transfers his mind into the body of Lukin through the powers of the Cube.
A fragment of a Cube empowered a new character that featured in a single storyline in Marvel Team-Up #20–24, and a Cube also appeared in Guardians of the Galaxy #19. The item added a new aspect to the abilities of the villain the Absorbing Man in The Mighty Avengers #32–33. A new Cosmic Cube was revealed in Avengers Assemble #5 ; it was revealed to be a working facsimile with more limited powers than the 'real thing'.

Fictional item history

The Cosmic Cubes are actually containment devices created by various civilizations throughout the Marvel Universe at various times. Examples including the Skrulls, and various other, unnamed civilizations. These matrices—which may or may not actually be shaped like a Cube—are suffused with reality-warping energies of unknown composition that comes from the realm of the Beyonders.
Unknown to almost everyone in the Marvel Universe, including its creators, the nature of the mysterious energies are such that, after a sufficient but undefined period of time, the matrix will become self-aware and evolve into an independent, free-willed being still possessed of the original Cube's tremendous powers; the new being's overall personality is psychically imprinted with the beliefs, desires, and personalities of those who wielded it as a Cube.
On Earth, the Cosmic Cube containment matrix was developed and created by an evil society of para-military scientists known as A.I.M. to further their ultimate goal of world conquest. The object is revealed to be so powerful that it drove to insanity its co-creator MODOK. Master villain and former Nazi the Red Skull obtains the device after taking control of the mind of the A.I.M. agent holding it, using a handheld device. Although apparently now all-powerful, the Skull became overconfident and was tricked and defeated by the hero Captain America, who pretended to surrender and ask to be the Skull's slave, then knocked the Cube away, causing it to fall into the ocean. It was found by Prince Namor after Hercules accidentally revealed it to him, but while battling the Avengers he lost contact with it, and it fell into the Earth. The Mole Man found it, but threw it away, not realizing its true value. Later, a shard of the Cube is also used by A.I.M. to power the android known as the Super-Adaptoid, who is sent in an unsuccessful attempt to kill Captain America.
The Red Skull eventually retrieves the Cube and toys with Captain America, but the Skull is defeated when A.I.M. uses an object called the "Catholite Block" to dissolve the Cube.
The Cube was eventually found by Thanos who, like the Red Skull, wishes to control the universe. Although opposed by superhero team the Avengers and the alien Kree warrior Captain Mar-Vell, Thanos becomes supreme when he wills the Cube to make him a part of—and therefore in control of—everything. Thanos discards the Cube, believing it to be drained of power, and is then stripped of the power by the dying superhero named Mar-Vell, who shatters the Cube and restores the universe.
Brought to research installation Project: Pegasus, the Cube was stolen by villain and cult leader Victorius, and is used to create the being Jude the Entropic Man. Both are neutralized when in simultaneous contact with the Cube. The Cube is returned to Pegasus by Captain America and the Fantastic Four member the Thing, where it eventually transforms the alien Wundarr into the entity the Aquarian.
A second Cube was created on the Island of Exiles by a team of scientists working for the Red Skull and the Hate-Monger. Planning to transfer his consciousness into the completed Cube, the Hate-Monger secretly arranged for a distraction in the form of a strike team from the spy organization S.H.I.E.L.D. attacking the island in an attempt to retrieve the Cube. However, the Red Skull was aware of his plans and had kept secret the fact that the Cube project had succeeded only in creating a perfect prison, but had failed to capture the mysterious, omnidimensional x-element which gives the Cubes their reality-warping power. As a result, the Hate-Monger's mind was left trapped in a powerless Cube in the Red Skull's possession. This Cube was one of the trophies that the Red Skull kept in his home, Skull House.
During a battle to stop A.I.M. from using the Cube once again, Captain America witnesses the Cube evolve into the entity called Kubik, which becomes a student of the Shaper of Worlds. Kubik returns to Earth when attracted by an possessing a fraction of its power, revealed to be the Super-Adaptoid. The Super-Adaptoid uses its abilities to "copy" Kubik's abilities and banishes the entity, intent on creating a race in its own image. The Adaptoid, however, is tricked into shutting down by Captain America. Kubik returns and then removes the sliver of the original Cosmic Cube from the Adaptoid that gave the robot its abilities.
Kubik also battles the renegade entity the Beyonder, and reveals to the entity and former Fantastic Four villain the Molecule Man that they are in fact both parts of an incomplete Cube, and convinces them to merge their powers. This forms a new being called Kosmos, who becomes the pupil of Kubik.
The character the Magus—an evil version of anti-hero Adam Warlock—acquires five Cosmic Cubes from neighboring universes, with each appearing in a different geometric form. The Magus uses mechanical aids to manipulate the Cubes, as their combined presence would quickly cause permanent brain damage. The character uses the Cubes to create evil doppelgangers of almost all of the Marvel heroes and then alters the universe, but is tricked and defeated when acquiring the Infinity Gauntlet, as the Reality Gem is revealed to be a fake, thus creating a gap in his powers.
Although the Magus is defeated, Warlock's "good side"—the female Goddess—also appears and wishes to purge the universe of all evil. To do this, she collects 30 containment units, with each storing the power of a Cosmic Cube, and merges them into a "Cosmic Egg". Despite the fact that the Egg can fulfill the Goddess' wishes—although, unlike the Infinity Gauntlet, it has no power over the soul—the character is defeated by Warlock and Thanos. During this time, the two questioned Mephisto about the origins of the Cubes in exchange for giving a Cube to Mephisto, but they were able to cheat the deal by giving Mephisto a drained Cube, as he never specified that the Cube had to still be functional.
A third Cosmic Cube was created by an Adaptoid-controlled faction of A.I.M. based on the island of Boca Caliente. This Cube was unstable and its reality-warping ability began to leak out onto the surrounding island, creating Cube constructs of anyone that was in the thoughts of nearby people. An Avengers team attempted to stop the Cube and the dying Captain America was willing to sacrifice himself to do so. In the end, it was an Adaptoid who had been accompanying Captain America and had been impressed by his heroic nature who ended the threat by willingly transforming itself into a non-sentient containment chamber for the Cube's energies.
The second Cube was eventually recovered by the KubeKult, fanatical followers of the Hate-Monger, who spied upon the A.I.M. Adaptoids and discovered how to power it. Fearing how the Hate-Monger would punish him for his betrayal, the Red Skull allied himself with then-rogue S.H.I.E.L.D. agent Sharon Carter to kidnap the dying Captain America and restore him to health. Reluctantly working together, the trio invaded a KubeKult base to steal the erratically functioning Cube, but the Red Skull seized it and willed Captain America to be drawn inside it into an artificial reality during World War II, where Captain America and Bucky were on a mission to kill Hitler. The Red Skull believed that he would be able to wield the Cube's power only if Captain America killed Hitler's consciousness within the Cube. However, the Bucky within the Cube revealed what was really going on and Captain America was able to will himself out of the Cube. Appearing before the Skull, Captain America threw his shield in such a way that it first severed the Skull's arm, causing him to drop the Cube, and then struck and shattered the Cube itself, causing an explosion that seemingly destroyed both itself and the Red Skull.
Months later, the Red Skull reappears, now with the Cube's power internalized within his body. He was approached by the time-traveler Kang the Conqueror, who told him that the reason he had failed to completely control the Cube's power in the past was because his knowledge of the universe was incomplete. At the suggestion of "Kang", the Skull willed the starship of Galactus to travel to Earth so he could drain it of the needed information. At the same time, Korvac appeared to Captain America and Sharon Carter and managed to convince them that the only way to prevent the Skull from becoming unstoppable was for Captain America to kill him during a brief moment of vulnerability. Captain America did so, but as the Skull died, his body released the Cube energy, which flowed into "Uatu", who revealed his true identity and used his increased power to return to his alternate 31st century Earth to conquer it. However, Captain America followed him and fought him repeatedly, with Korvac rebooting the 31st century reality each time Captain America disturbed his perfectly ordered machine world. Eventually, Captain America managed to convince Korvac that the reason he was able to achieve anything at all against Korvac was due to there being too much humanity left within Korvac when he acquired the Cube's power. Accordingly, Korvac transported himself and Captain America back to just before the Skull died, but this time Captain America did not strike the fatal blow. Vulnerable to the Skull's power, Korvac teleported himself, Captain America and Carter aboard the starship, but the Skull soon found him and scattered Korvac across six dimensions. Soon afterwards, the Skull was tricked by Captain America into entering an anti-matter energy beam within the starship's engine room, which separated the Cube energy from him. Before the energy dissipated, Captain America and the Skull were each able to use its wish-granting ability to save themselves and Carter from death.
A Cosmic Cube was one of the 12 items of power sought by superhero teams the Avengers and the Justice League of America when they competed against each other in a game organized by Krona and the Grandmaster. It was the final item of the quest, found in the Savage Land, where both teams converged for a full-scale fight, during which Green Lantern Kyle Rayner was able to use the Cube as a substitute power source for his power ring when his usual battery had been stolen and the ring was running out of power. Quicksilver was finally able to gain the Cube, bringing the game to a stalemate, but to make sure Krona lost, Captain America helped Batman to take it, because they were the only ones, aside from the Atom, who knew the true stakes of the game: Krona had forced the Grandmaster to take the Justice League as his representatives, so the League had to win in order to prevent Krona from destroying the Marvel Universe. Batman briefly attempted to use the Cube to end the game — having been filled in on its capabilities by Captain America — before the Grandmaster took it from him to tally up the score. Enraged at his loss, Krona attacked the Grandmaster, who then used the Cube along with all other items of power to temporarily fuse the Marvel and DC Universes and imprison Krona in the intersection, hoping he would be unable to destroy a universe if his own existence were linked to it.
The Red Skull has finally created one by using pieces of the previous Cubes, and Aleksander Lukin wants it as much. The Red Skull is assassinated by the one person that Lukin was willing to trade for the Cube—the Winter Soldier. In the process of being assassinated, the Skull uses the Cube's power to transfer his mind into the body of Lukin for some time.
A youth called Curtis Doyle becomes the hero Freedom Ring when he finds a fragment of the original Cube in the form of a ring, which allows the altering of reality in a very limited area of 15 feet around the wearer. The character dies in battle saving Captain America, Spider-Man, Spider-Woman, and Wolverine from the villain Iron Maniac. The ring is later found by a friend of Doyle, a Skrull who had settled on Earth and adopts the name the 'Crusader'.
The powerful entity D'Spayre attempted to enhance his power by using a Cosmic Cube to draw on the grief of the general public in the aftermath of Captain America's assassination, only for his use of the Cube to have an apparently unintended side-effect when it granted the 'wish' of those who wanted Captain America back by drawing the Invaders into the present. He was defeated in a confrontation with the New Avengers when Echo proved immune to his powers due to her deafness, allowing her to take the Cube from him. The Cube is then used by Paul Anslem, a World War II soldier who had traveled with the Invaders against his will. Anslem's intentions to save his friends, who had died during an assault on a Nazi stronghold, allows the Red Skull of the World War II era to gain enough power to take over Earth. Anslem again regains control of the Cube with super-powered assistance and restores the timeline to what it should have been.
A Cube is also given to Guardians of the Galaxy member Star-Lord by time-traveling villain Kang the Conqueror to use against Adam Warlock's evil alter ego, the Magus. However, the Magus altered perception to make it seem like the Cube's power was used up. Star-Lord used the Cube's last bit of energy for real by subduing the reborn Thanos, rendering it a "cosmic paperweight".
The Absorbing Man becomes capable of assimilating the abilities of a fraction of a Cube. He is stopped by criminal mastermind Norman Osborn, who uses a magical sword to neutralize the Absorbing Man's abilities.
A new Cosmic Cube is later revealed to have been created by the U.S. government. It is stolen by members of the Zodiac at the behest of Thanos. Thanos' plot is later foiled by the combined might of the Avengers and the Guardians of the Galaxy.
During the ' storyline, Maria Hill and the rest of S.H.I.E.L.D. used pieces of a Cosmic Cube to create ', a near-omnipotent child, originally conceived by Longshot and the Cosmic Cube "Miss Grapples". With Kobik's help, S.H.I.E.L.D. began brainwashing supervillains into becoming mild-mannered civilians, who were then imprisoned in a gated community called Pleasant Hill. When the villains rebel, Kobik decides to bring Steve Rogers, then reduced to an old man due to the breakdown of his Super-Soldier serum, back to his physical peak, but due to the Red Skull's influence over the Cube from which Kobik was made, she unknowingly replaces Rogers with a covert HYDRA loyalist version of him, believing that to be the "right" version of him. This results in the real Rogers' consciousness becoming trapped within the Cube until he finds Kobik and encourages her to set things right by showing the atrocities his doppelgänger had committed in the name of HYDRA during the Secret Empire'' storyline; she then brings him back to the real world, with some help from the heroes outside.

Video games

In Lego Marvel Super Heroes, Silver Surfer has a board made of "Cosmic Bricks" instead of just one Cosmic Cube. The bricks are collected throughout the game and many heroes race to get them before the villains, mainly Doctor Doom and Loki, do. The Tesseract itself appears in the game when Captain America, Thor, the Human Torch, and Wolverine have to go retrieve it. They succeed in recovering it. While everyone is discussing how to deal with it, Wolverine takes the "Glow Cube" for himself and brings it to the X-Mansion, hoping that Professor X will use it to locate Magneto. Magneto and the Brotherhood of Mutants then break in and take the Tesseract. Magneto takes the Cube to Doctor Doom who is going to use it in a ray gun to save the world from Galactus' hunger by controlling his mind, but Loki uses his magic mind control to make Doom hide that fact instead saying that he would use it to enslave the world. After Doctor Doom is defeated, Loki reveals its true purpose as a mind-control ray with the Tesseract serving as an infinite power source. He uses it on Galactus to destroy Earth and Asgard, but an alliance of Marvel heroes and villains puts a stop to it as they send Galactus and Loki elsewhere in space using a wormhole while S.H.I.E.L.D. takes the Cosmic Cube.
