In Marvel continuity, Hitler didn't die by suicide either-- it was the original, android Human Torch who killed him. Yet Hitler died knowing he would be reborn into a cloned body. In the Ku Klux Klan-influenced Hate-Monger costume, Hitler fought the Fantastic Four, Nick Fury and others to bring back the Third Reich, mostly by bombarding everyone he could reach with "hate rays" to make them more racist.
