10 DC Characters Who Killed Superman (And What Happened To Them)
7. He-Man
There's a fair list of characters you'd expect have killed Superman in some continuity or another; Doomsday, Luthor, Bizarro - really, any major villain in the hero's roster has a good chance of making it. A name you wouldn't expect to be on that list, however, is none other than He-Man - and yet, he very much has killed Superman, and wasn't at all sorry.
The DC Universe vs. The Master of the Universe comic was likely made explicitly in order to feature Superman and He-Man going toe-to-toe, and in this it doesn't disappoint. By the second issue, Prince Adam and a mind-controlled Man of Steel are already exchanging blows - right up until He-Man stabs Superman right in the heart, which kills the superhero so hard that he dissolves into dust some pages later.
It would later be revealed that this dust-death was actually down to He-Man not killing the real Superman, but rather an evil clone created by Lord Orko - He-Man's greatest enemy, and also the mastermind who initially mind-controlled the rest of the Justice League. This said, He-Man did still technically kill Superman - just not the Superman - which is kind of balanced out when the two fight Orko together.
