The Tesseract is a cube-shaped containment vessel for an object of limitless power known as an Infinity Stone from the Marvel Cinematic Universe. It made its Convergence debut in The Ties That Bind, though chronologically was first relevant during Genesis.
Plot Involvement Edit
The Tesseract was originally intended to be used as an unlimited source of power, allowing whatever was connected to it to remain active indefinitely, but has since been used to invent marvels of technology. It is an item that has been sought by many individuals, including the Arch Demon.
A Tesseract was given by Xehanort to Umbrella, who fought a heavy battle with S.H.I.E.L.D. over the item. In an attempt to secure the item for himself, the Arch Demon, then known as Diablo, infiltrated Umbrella with Albert Wesker as his ally.
Umbrella gathered individuals across the multiverse and implanted devices into their heads to force them to work for the group and fight against S.H.I.E.L.D., who desired to take back the Tesseract stolen from them. The Avengers soon deactivated the devices and S.H.I.E.L.D. recruited the survivors to assist them in recovering the Tesseract.
The Ties That Bind Edit
Physically, it is little more than a blue cube, usually glowing with blue cosmic energy. However, despite its simplistic appearance, it is far more powerful than one might assume at first glance.
The Tesseract is an Infinity Stone, representing the fabric of space. If used correctly, the Tesseract can open gateways to any part of the universe, and it is presumable that it grants omnipresence when used at full potential.
It can be used to restore objects and artifacts of incredible power. Also, to perform these functions, it produces limitless energy. A single spark of its power was enough to create a small explosion.
