Over the course of his career, Walter "Walt" Simonson has written and drawn nearly every major character from both Marvel and DC Comics. Notable works include an adaptation of Alien, once again with his Manhunter collaborator and close friend, Archie Goodwin, Star Wars, The Fantastic Four, Orion and Elric. In the 1980s and 1990s Simonson resurrected the concepts from his college thesis, creating an original graphic novel and miniseries featuring the Star Slammers. In 2014 Simonson launched Ragnarök with IDW Publishing, a creator-owned series that once again brings him back to his beloved Norse mythology.
