Synopsis for "When Warriors Clash!"
Thor goes on one final quest before returning to Earth. He follows a griffin-like creature through a portal to Avalon. There he battles Leir after a misunderstanding until Leir spots the creature as well. With the help of Hogun, they drive the creature back to Asgard, where it is defeated by Fandral and Volstagg. Thor goes to leave for Earth, but the warning comes too late. Asgard is adrift without Bifrost to anchor it, and Thor has transported himself into the depths of airless space.
