Moments before Glaive kills him, Heimdall uses the power of the Bifrost to send Hulk to Earth.
After a futile counter-attack from the Hulk, Loki offers the Tesseract to Thanos in exchange for Thor’s life – only to Avengers: Infinity War be killed himself when Thanos anticipates Loki’s attempt to betray and kill him. With Thanos already possessing the Power Stone after decimating Xandar, Thanos’ army swiftly defeats the Asgardians. Thanos and his Children – Proxima Midnight, Ebony Maw, Corvus Glaive and Cull Obsidian – have attacked Thor’s Asgardian ship in search of the Space Stone, which is housed in the Tesseract that Loki had stolen before Asgard’s destruction. Everything the Avengers have fought for has led up to this moment – the fate of Earth and existence itself has never been more uncertain. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality.
As the Avengers: Infinity War and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos.
