10 DC Characters Who Killed Superman (And What Happened To Them)
4. Doomsday
Doomsday's drawn out murder of the Man of Steel in the Death of Superman comic is something of a cultural cornerstone of the DC universe, and it's a great mercy that it is, as it's potentially the single greatest comic to ever feature DC's most famous hero dying.
In a story that serves to properly establish both Doomsday and Superman as absolute badasses, the roughly hundred-page fight manages to stay gripping the entire way through, which is no small task for what is essentially endless pages of two huge dudes punching each other.
As the fight grows out of hand, Superman realises that this is one battle he may not make it out of, and says his goodbyes to Lois Lane before breaking into the last round of the fight, which would see the Kansas-grown hero finally defeat the hulking brute - but at the cost of his own life.
