* HilariousInHindsight: During "Reign of the Superman" a fan commented in his letter that "It's amazing how far comics have come in twenty years. Then Doomsday would have been some monster thrown from Krypton or something". When Doomsday's origin was eventually revealed, it turned out comics actually hadn't changed that much.
* LikeYouWouldReallyDoIt: Kill DC's practical {{Mascot}} permanently? Yeah, right.
** As Creator/MaxLandis "educational parody film" ''[[http://www.youtube.com/watch?v=0PlwDbSYicM The Death and Return of Superman]]'' explains, this wasn't really the attitude of comic book readers at the time. At the time, death wasn't something focused on in comic books, especially the main characters dying. As such, when TheCape himself died, it was a big thing for both readers and people who didn't even bother reading comics. What caused this trope, then? After it happened to Superman, '''every''' comic book with a dead character decided that it would be equally cool to return.
-->'''MAX:''' "The [[WillingSuspensionOfDisbelief Sacred Suspension of Disbelief]] had ended. 'Death of Superman' didn't kill Superman. It killed ''death''."
* MoralEventHorizon: The destruction of Coast City. Mongul [[spoiler:and Cyborg Superman]] killed ''seven million people''.
* SeinfeldIsUnfunny: Because of the "DeathIsCheap" trope (whose former {{Trope Namer|s}} is "Comic Book Death"), this story is hard to take seriously today. However, it's believed to be the {{Trope Maker|s}} ''for'' DeathIsCheap, so at the time it was a big deal. Heck, it made ''the nightly news'', at a time when ComicBooks were believed to be culturally irrelevant.
** It was hard to take seriously at the time for comics fans, given that NeverFoundTheBody predates the medium, and [[XMen Jean Grey]] had [[OlderThanTheyThink already returned from the grave.]] Heck, even mainstream {{Superhero}} TV show pulled this stunt before such as ''Series/TheSixMillionDollarMan'' in the 1970s reviving the supposedly deceased Jamie Sommers for her own series, ''Series/TheBionicWoman''. Superman's death is the TropeCodifier.
* TearJerker: Comes with the territory. Watching Superman's last blows with Doomsday, as his friends, colleagues, and family watch helplessly, is truly heart breaking.
