Tesseract

The Tesseract, also called the Cube, was a crystalline cube-shaped containment vessel for the Space Stone, one of the six Infinity Stones that predate the universe and possess unlimited energy. It was used by various ancient civilizations before coming into Asgardian hands, kept inside Odin's Vault. Eventually, it was brought to Earth and left in Tønsberg, where it was guarded by devout Asgardian worshipers.
In 1942, the Tesseract was retrieved by Johann Schmidt, the leader of HYDRA, who used the Tesseract to power enhanced weaponry in order to defeat the Allies during World War II. Following Schmidt's defeat at the hands of Captain America in 1945, the Tesseract fell into Arctic waters, where it was recovered by Howard Stark. The Tesseract was then kept at Camp Lehigh in New Jersey, where it remained until at least 1970.
Spending decades attempting to harness its power, Stark eventually helped found Project P.E.G.A.S.U.S., to whom he relinquished custody of the Tesseract in the 1980s. Mar-Vell, an undercover Kree scientist, joined P.E.G.A.S.U.S. and harnessed the Tesseract's power to create the Light-Speed Engine to assist the Skrulls in their war against the Kree and took possession of the Tesseract, storing it in her laboratory in orbit. In 1989, Yon-Rogg killed Lawson to obtain the Tesseract, but pilot Carol Danvers destroyed the engine, causing her to be doused in Tesseract energy. Six years later, Danvers, now Captain Marvel, recovered the Tesseract from Lawson's laboratory and renounced custody of it to S.H.I.E.L.D.
It remained in their possession until 2012, when it was stolen by Loki who used the Tesseract to open a wormhole and allow the Chitauri to invade New York City. Following the Battle of New York, the Tesseract was acquired by Thor, who brought it back with him to Asgard.
After using the Tesseract to repair the Rainbow Bridge, Odin tasked Heimdall, the realm's gatekeeper, with the task of protecting the Tesseract. However, after Loki usurped the throne and disguised himself as Odin, he charged Heimdall with treason, forcing the gatekeeper to flee, while the Tesseract was placed within Odin's vault once more.
During the destruction of Asgard, Loki noticed the Tesseract and took it for himself before the vault, along with the planet, were destroyed. Thanos later acquired the Tesseract and crushed it to unveil the Space Stone within and then inserted the stone into his Infinity Gauntlet.
In 2023, the Avengers initiated a Time Heist in order to resurrect the lives claimed by the Snap. Captain America, Iron Man, Hulk, and Ant-Man were sent back in time to 2012 during the Battle of New York to retrieve the Time, Mind, and Space Stone, the latter housed within the Tesseract. However, in this alternate timeline, Loki was able to get the Tesseract and used it to escape custody, forcing Captain America and Iron Man to travel to an alternate 1970 to retrieve another Tesseract. Following the Battle of Earth, where Iron Man used all six stones to kill Thanos and his army at the cost of his own life, Captain America time-traveled to the alternate 1970 to return the Space Stone, albeit without the Tesseract.
==History==
===Origins===
In the wake of the universe's creation, there were six singularities that were forged into the Infinity Stones. The Tesseract was created as a containment vessel for the Space Stone. Within the Tesseract, the Stone was owned and used by various civilizations to achieve their ends.
===Ancient Times===
The Tesseract was eventually acquired by the Asgardians during Odin's rule and was locked away in Odin's Vault. Upon quelling wars across the Nine Realms, Odin brought the Tesseract to Earth, visiting the village of Tønsberg in Norway where the Asgardians were worshiped as deities. He entrusted the Tesseract to the care of his devout worshipers in Tønsberg, causing the cube to become the subject of many legends of Norse mythology.
===World War II===
In March 1942, during World War II, HYDRA forces led by Johann Schmidt invaded Tønsberg where he found the Tesseract in a box hidden behind a sculptured mural of Yggdrasil, the world tree. Schmidt took the Tesseract back to HYDRA Headquarters to be the subject of experiments by Arnim Zola. After experimenting on the Tesseract, Schmidt and Zola were able to harness the object's power to create highly advanced weaponry, fueling Schmidt's plans for world domination. Werner Reinhardt also worked on the Tesseract while it was in HYDRA's possession.Avengers: Endgame - Cantina Creative
Zola created batteries that contained the power of the Tesseract, which were then used by Zola and a handful of HYDRA scientists to power their weaponry. With the power of the Tesseract, Schmidt felt strong enough to turn his back on Adolf Hitler and the . He intended to destroy both the Axis and Allied powers and make himself ruler of the world.
In November 1943, Schmidt brought the Tesseract into HYDRA's top secret weapons facility in the Austrian Alps, located halfway between and . While the facility was in operation, Allied Prisoners of War were forced to serve in the large-scale assembly of Tesseract-based energy weapons, including the Valkyrie super-bomber, and a set of nuclear-scale Tesseract energy bombs. When the Allied super soldier Captain America infiltrated the facility to free the four hundred Allied POWs, a large confrontation began. Seeing that his men wouldn't be able to defeat the freed prisoners, Schmidt took the Tesseract and set the base to self-destruct.
In February 1945, with his gigantic super bomber, the Valkyrie, finally finished, Schmidt was prepared to launch an offensive that would shake the entire planet. Utilizing his Tesseract-powered energy bombs, Schmidt intended to bring the United States to its knees by bombing heavily populated cities across the country. However, his last base was attacked by Rogers, the Howling Commandos, and a United States Army division led by Chester Phillips and Peggy Carter.
Schmidt's men were defeated, but he managed to take the Tesseract and launch the Valkyrie. However, Rogers managed to board the plane and attacked Schmidt, damaging the machine that was using the Tesseract to power the Valkyrie and its energy bombs. Angered, Schmidt grabbed the Tesseract, only for the object to open a portal which transported him to Vormir where he became the keeper of the Soul Stone. The Tesseract fell to the plane's floor and, super-heated with energy, burned through the fuselage, causing it to plunge into the sea below. Sometime later, it was recovered by Howard Stark who was searching for Rogers.
A group of former HYDRA scientists managed to escape to South America where they were employed by the government of Peru to make a powerful weapon while using Zola's discoveries of the Tesseract's energy. The scientists were successful, but because the Tesseract's energy was unstable, the weapon ended up stuck in an undiscovered Incan temple.
===Project P.E.G.A.S.U.S.===
Following the war, Howard Stark studied the Tesseract for some time, recording his research in a notebook. Stark and S.H.I.E.L.D. had the Tesseract relocated to Camp Lehigh in New Jersey, where it remained in storage for many decades. Believing that the energy within the Tesseract would be beneficial to mankind, Stark was instrumental in the creation of Project P.E.G.A.S.U.S., a joint venture between S.H.I.E.L.D., NASA and the United States Air Force tasked with studying and harnessing the Tesseract's energy. Stark relinquished custody of the Tesseract to P.E.G.A.S.U.S.
The Kree scientist Mar-Vell, who had taken on the guise of a human and was calling herself Doctor Wendy Lawson, joined the project with the goal of harnessing the Tesseract's power to create a Light-Speed Engine for the Skrull refugees under her protection. The Tesseract was eventually relocated to Mar-Vell's orbital laboratory, where it remained untouched for six years.
When Carol Danvers and Nick Fury arrived at the lab, they placed the Tesseract in a lunchbox, attempting to smuggle it out before the Starforce arrived, demanding the artifact. Goose, a Flerken, swallowed the Tesseract while Danvers led her former allies on a diversionary chase for the empty lunchbox. Once the Kree and Skrulls had left Earth, Goose regurgitated the Tesseract on Fury's desk.
===In the Possession of S.H.I.E.L.D.===
Following its regurgitation, the Tesseract returned to S.H.I.E.L.D.'s possession with the World Security Council ordering S.H.I.E.L.D. to use the cube to develop advanced weapons and better defend the Earth from any extraterrestrial threats.The Avengers Prelude: Fury's Big Week
After the Battle of Puente Antiguo in New Mexico during which Thor defeated the Destroyer, humanity finally realized they were not alone in the universe. Erik Selvig was assigned by Nick Fury to research and study the Tesseract with hopes of unlocking its power just as Johann Schmidt had.Thor Post-credits Scene Later, the Tesseract was moved to the Joint Dark Energy Mission Facility in the Mojave Desert, where Fury also positioned Clint Barton to keep guard over Selvig and the Tesseract.
===War for Earth===
 
In 2012, Loki came into contact with Thanos, powerful warlord and the master of Chitauri. Thanos had already been seeking the Tesseract in order to retrieve the Space Stone, and Loki promised to retrieve it from Earth and give it to him in exchange for his army. Through manipulation of the Tesseract's energy, Thanos teleported Loki to the Joint Dark Energy Mission Facility where he killed several S.H.I.E.L.D. agents and enthralled Erik Selvig, Clint Barton, and other agents.
Loki revealed his plans to use the Tesseract to enslave and rule over the human race, stole it, and escaped. The energy from the portal destroyed the facility, while Loki took the Tesseract to an undisclosed location.
In response to Loki's threat, S.H.I.E.L.D. decided to re-start the Avengers Initiative and swayed Bruce Banner, Tony Stark, and Steve Rogers to their cause. Nick Fury also wanted them to trace the Tesseract as it was emitting small amounts of gamma radiation that only Banner and Stark would be able to trace.
While Loki was dealing with the Avengers, he ordered Selvig to begin working on an upgraded version of the Tesseract Accelerator that could utilize the Tesseract's full power to create a portal that could transport the Chitauri army to Earth. Selvig and Loki later put their plan into effect and opened the portal above Stark Tower in New York City, which unleashed the Chitauri upon the city and an immense battle ensued.
Eventually, Black Widow used Loki's Scepter to reverse the effects of the device, shutting down the Tesseract and closing the portal. Following the invasion, Thor returned Loki and the Tesseract to Asgard. Though the World Security Council disapproved, Fury defended his decision to allow Thor to take the Tesseract to Asgard, saying that humanity was not ready for the Tesseract's power, much to the council's dismay.
===Back on Asgard===
|Hela making a comment about the Tesseract
 
After his return to Asgard, Thor gave the Tesseract to Heimdall. The all-seeing Asgardian used the Tesseract to repair the Bifrost Bridge so the Asgardians could once again protect all of the inhabitants of the Nine Realms endangered by the Marauders.Thor: The Dark World Prelude
Later, the Tesseract was locked in Odin's Vault so no one could use it again without Odin's permission. Hela noticed the Tesseract as she was walking in the vault, and she admitted the power of the cube. During Ragnarök, when Loki was about to resurrect Surtur in order to defeat Hela, he decided to take the Tesseract before also taking the Crown of Black Fire.
===Destroyed by Thanos===
Having located the Tesseract on the Statesman, Thanos and the Black Order traveled with the Sanctuary II and attacked the ship. They killed half of the Asgardian survivors and captured Thor and Loki. Thanos tortured Thor with the Power Stone in order to make Loki give him the Tesseract. Loki acceded to his demands, though he managed to stall long enough for Hulk to ambush Thanos. But Hulk was swiftly defeated. Afterward, Ebony Maw retrieved the Tesseract and presented it to Thanos, who proceeded to effortlessly crush the Tesseract in his hand and placed the Space Stone in his Infinity Gauntlet.
===Alternate Universe Versions===

====Taken by Loki====
In 2023, five years after the Snap, Tony Stark devised a method to use the Quantum Realm in order to travel through time safely. In order to resurrect the victims of the Snap, the Avengers subsequently initiated a Time Heist, where they would travel through the Multiverse to alternate past timelines in order to reclaim all six Infinity Stones and bring them to their time. In order to retrieve the Space Stone, Stark, along Steve Rogers, Bruce Banner and Scott Lang, were sent back in time to the Battle of New York, back when the stone was inside the Tesseract, creating an alternate timeline in the process.
It was accompanied by a team of S.H.I.E.L.D. agents and the alternate versions of Tony Stark and Thor, who planned to take the Tesseract and Loki back to Asgard. However, on their way out of Stark Tower they were stopped by Alexander Pierce, who demanded the Tesseract as it was S.H.I.E.L.D. property since World War II.
While the entire hall argued, the older Stark instructed Ant-Man to go inside his 2012 self's Arc Reactor and disable it, causing him a cardiac arrest as a distraction. As the 2012 Stark collapsed, Ant-Man kicked the case containing the Tesseract away from them, his actions being noticed by Loki. As the elder Stark attempted to flee, he was struck by the 2012 Hulk, causing the case to open and the Tesseract to skid across the floor, stopping by Loki's feet. Noticing that the agents surrounding him were preoccupied with Stark's heart attack as well as the sudden appearance of an angry Hulk, Loki took the opportunity to seize the Tesseract, using the Space Stone within to create a wormhole and escape confinement.
Arriving in the Gobi Desert in Mongolia, Loki and the Tesseract were swiftly found and taken by the Time Variance Authority to their headquarters. The Tesseract was confiscated by the TVA and placed into evidence by a TVA worker named Casey, where it was held in a drawer with other Infinity Stones from alternate timelines. Later, Loki retrieved the Tesseract and attempted to use it to escape the TVA, but discovered that it had no power within the confines of the TVA headquarters.
====Theft of the Space Stone====
After failing to acquire the alternate 2012 version of the Tesseract, Tony Stark and Scott Lang retreated to their rendezvous point, informing Steve Rogers of their failure. Rogers inquired as to whether there was another place in time where they could safely steal the cube, only to be reminded by Lang that they each only had one Pym Particle left, which was only enough for the trip home. As they lamented in their current situation, Stark remembered that Howard Stark and Hank Pym both worked at Camp Lehigh in New Jersey around April 7, 1970, meaning that both the Tesseract and a supply of Pym Particles would be stored there. Arriving in an alternate 1970, Stark successfully infiltrated the base with Rogers, and using his glasses to search for a gamma signature was able to locate the Tesseract, placing it within a discarded briefcase.
After successfully transporting the past versions of the Infinity Stones to the main timeline, the Space Stone was extracted from the Tesseract and placed within the Nano Gauntlet. Wearing the gauntlet, Bruce Banner harnessed the power of the six stones to resurrect the lives claimed by Thanos' Snap, albeit losing the ability to use his right arm in the process.
====Powering the HYDRA Stomper====
In the alternate universe, the Tesseract was taken from the Castle Rock Tower by Johann Schmidt, after HYDRA forces attacked Tønsberg. Schmidt entrusted Arnim Zola with transporting the Tesseract to the headquarters, however, the convoy was attacked by Captain Carter, who took both Tesseract and Zola into the SSR's custody. Conducting his research, Howard Stark used the Tesseract to power the suit of armor he created for Steve Rogers, so he could join the war effort.
However, during the Attack on the Schnellzug EB912, Rogers and his armor were captured by HYDRA. With the Tesseract in his possession, Red Skull opened an inter-dimensional portal and summon the creature that he dubbed "the Champion of HYDRA", that he intended to use to gain the ultimate power. However, the Champion killed Red Skull and fought Carter and the Howling Commandos, while Stark sought a way to prevent the creature from emerging onto Earth. Eventually, Carter managed to push the Champion back into the portal by entering it herself, allowing Stark to close the portal.
Decades later, the Tesseract ended up in S.H.I.E.L.D. possession and was used for the Project P.E.G.A.S.U.S., as S.H.I.E.L.D. sought a source of unlimited energy. When they managed to reignite the Tesseract, it opened a portal, from which Carter managed to return to Earth, although Nick Fury and Clint Barton informed her that the war ended seventy years ago.

====Destruction of Project Rebirth====
In the alternate universe, the Tesseract ended up in possession of HYDRA, and as they did not face significant resistance, its powers allowed HYDRA to win the World War II. HYDRA's reign, however, had disastrous consequences, turning the world into a desolate wasteland.
==Capabilities==
The Tesseract was a cube which contained the Space Stone, an Infinity Stone representing the element of space. The Tesseract could open wormholes to any part of the universe and provide interdimensional travel. Touching the Tesseract physically, Red Skull was suddenly transported to Vormir where the Soul Stone chose him as a Stonekeeper. Using the Mind Stone inside the Scepter, Loki was able to remotely access the Tesseract, which was on Earth, and opened a portal that transported him to the Joint Dark Energy Mission Facility. With its power, Erik Selvig was able to construct a device that opened an enormous wormhole for the Chitauri army to invade New York.
It was theorized to be an unlimited source of energy because it drew cosmic energy from space. It appeared to possess intelligence, or will; when Selvig was studying it, he noted that it "behaved" as though it had awareness. When the power used to harness its energy was cut off, the Tesseract turned the power back on. The Tesseract was able to recognize Schmidt as "unworthy" to possess the Space Stone within, which is why it opened the portal to Vormir. The Tesseract emitted low levels of gamma radiation, which interfered with Selvig's methods to harness its energy source, and later allowed S.H.I.E.L.D. to track its movements.
As a power source, it could be used to power objects and artifacts of incredible scale, such as the Bifrost Bridge. A single spark of its power was enough to create a small explosion. When Mar-Vell's Tesseract-powered Light-Speed Engine exploded, the released cosmic force imbued Carol Danvers with the ability to manipulate energy itself. She could, for example, use energy to propel herself through the air, and emit energy blasts from her hands. HYDRA was able to use the Tesseract to power advanced vehicles and weapons of mass destruction including guns, tanks, and bombs that vaporized their targets. When active, it could melt through steel although it could be held using gloves for a short time, or when handled in special containment units. It could also be handled directly by exceptionally powerful beings such as Captain Marvel, Goose, Loki, Ebony Maw, and Thanos.
The Tesseract required a heat of at least 120,000,000 Kelvin to break through its Coulomb barrier and activate its full power.
===Tesseract Energy===
Many people have tried to duplicate the type of energy that the Tesseract emitted. The only people that are known to have successfully harnessed the Tesseract's energy were Mar-Vell, Johann Schmidt and Arnim Zola. Zola developed a method to siphon off and store its energy with a Cube Cartridge to power weapons. Former HYDRA scientists were able to replicate the power of the Tesseract and create a powerful laser weapon for the Peruvian government. Mar-Vell developed the Light-Speed Engine using the energy of the Tesseract to help aid the Skrulls in ending the Kree-Skrull War. When the Light-Speed Engine exploded, Captain Marvel absorbed the energy of the Tesseract and gained cosmic powers. Howard Stark discovered a way to make an element with a similar type of energy, but because of the technological limitations of his era, he was not able to bring his discovery to fruition. Years later, Tony Stark was able to make the element based on his father's research. The element was used as the core for a new Arc Reactor that would stop Stark's palladium poisoning.

==Trivia==
*In the comics, the Cosmic Cubes are cube-shaped matrices that can control matter and energy, and allow their users to shape reality. The cubes were used by different species, like the Beyonders, the Kree, the Skrulls and Humans like Red Skull and A.I.M. members.
==Behind the Scenes==
*In The Art of Captain America: The First Avenger, the Tesseract is referred to as the Cosmic Cube.
**In it, Stephen Broussard explained why they changed its power: "In the comics, the Cosmic Cube was this omnipotent device that if you thought it, it happened. Obviously, if you give your bad guy that, it's a little too powerful."
