History
Thor shared a similar history to his Earth-616 counterpart until the weapon used by Iron Man to incapacitate the Hulk destroyed New York and every hero present. The alien Skrulls took the Hulk's invasion as a sign to launch their own attack on Earth, there first mission was to activate there sleep agents and kill all of Earth's super-heroes. Thor was involved in one of these battles and killed by the Skrulls.[1]
