Thanos w/ his army vs. Asgard
In this scenario, Loki never deposed Odin and sent him to Earth. Odin found out about Loki's scheme and locked him up in his old prison cell. Thor returns to Asgard and warns Odin of impending Ragnarok and Odin takes this warning seriously. Asgard's shields are turned on and all its warriors are put on high alert. Even Loki is allowed out of his prison to fight for Asgard.
Thanos with his army and the Black Order then arrive on Asgard aiming to retrieve the Tesseract. Thanos already has the power stone at this point. Will Thanos be victorious in acquiring the space stone?
Can he and his army beat Odin, Thor, and the full might of Asgard?
