Thor subsequently leads the Avengers against the forces of Asgard, leaving Iron Man and Loki (who once again attempted to seize rulership of Asgard during the conflict) dead and forcing Thor himself into self-imposed banishment for almost destroying Asgard in his selfishness.
Following this, Thor takes charge of the Avengers against the Asgardian forces, resulting in Iron Man and Loki's deaths as well as forcing Thor to voluntarily banish himself from Asgard due to his own reckless actions during the conflict.
