DC Comics has been putting out superhero comics for close to a hundred years. Over the decades, DC's creators have told every kind of story imaginable, building up the heroes and villains of the DC Multiverse into beloved icons. However, not every story is meant to build a character up. Stories like The Death of Superman tear major characters down, destroying them so they can grow in new ways or be replaced. These stories play a key role in superheroes' lives.
