With Avengers:End Game approaching the big screens, new spoilers and fan theories every other day have increased the excitement for the film immensely. Between all the fan theories, spoilers and rumours spread around, the questions about the TESSERACT still remains a mystery. For many years TESSERACT has been a crucial part of the plot of the MCU movies.
TESSERACT in the past movies has been delineated as a mysterious squared box that contains infinite powers including the ability to teleport its master anywhere in the universe.
After The Big Bang, six primary elemental singularities resulted in the formation of the Six Infinity Stones; The Space Stone (blue), the Reality Stone (red), the Power Stone (purple), the Mind Stone (yellow), the Time Stone (green) and the Soul Stone (orange).
Tesseract was originally created as a containment vessel for the Space Stone, to tame the raw power of the Space Stone and make it easily controllable.
CAPTAIN AMERICA: THE FIRST AVENGER
Tesseract made its first debut in The First Avenger, where the vigorous blue square box was used by the Red Skull to create powerful weapons and destroy the Allies during World War II. Later in an action packed fight with Captain America, he bare handedly tries to control the power of Tesseract to turn the tables, but fails miserably as the stone opens a wormhole and sucks Red Skull into it. Resulting in the falling of Tesseract out of the plane into the depths of the ocean.
Howard Stark recovers the Tesseract form the bottom of the ocean, of which a miniature version is later used by his son Tony Stark to power the Iron Man Suit.
Further, the Tesseract is seen controlled by Loki in The Avengers where he opens a space portal above New York city using the energy of the cube.
Taken back to Asgard by Thor in the end of The Avengers when Thor’s sister Hela tries to destroy Asgard, Loki The God of Mischief but now a good guy steals the cube for himself.
AVENGERS: INFINITY WAR
At the beginning of Infinity War, Thanos overtakes the Ship of the Asgardians and demands Thor for the Tesseract, denying to the fact of Tesseract being destroyed, Loki gives Thanos the Tesseract when he threatens to kill Thor.
Thanos kills Loki and takes the Tesseract, he crushes the Tesseract to reveal the Space Stone and adds the sixth infinity stone to his Infinity Gauntlet and wipes out half of the universe including several Avengers.
WHAT’S NEXT ?
The Tesseract has been an important part of major MCU movies, a few fan theories suggest that the Tesseract can be used by the remaining Avengers to fight against Thanos in Avengers: End Game. Reportedly, many fan theories state that the only way the Avengers can defeat Thanos is to travel back in time to collect each of the Infinity Stones and undo the damage which Josh Brolin’s character caused. Perhaps Goose storing the Tesseract in the ’90s will allow some of the time-traveling Avengers to meet the Flerken and retrieve the Space Stone.
