History
As it happened on Earth-616, the original Avengers formed when Loki tried to lure his brother Thor into battle with the Hulk. In this reality, however, Loki murdered Giant-Man for getting between him and Thor. In vengeance, Thor struck Loki with all of Mjolnir's might, and the God of Mischief vanished.[1]
Notes
This Hulk appeared to be an amalgam of Ghoul and Bruce Banner.
