!!YMMV: Infinite Crisis Comic
* CompleteMonster: Superboy-Prime begins his descent towards the trope here, killing multiple superheroes, and then blaming them for it, trying to kill Superboy so that he can take his place, trying to kill the entire universe so that he can have ''his'' world back(though in fairness, [[RealLife its our world as well]]), and finally [[spoiler:beats Kal-L to death]] with his bare hands. Some feel that he hit CM status here, others think that didn't happen until the ''Sinestro Corps War'' or even ''Legion of Three Worlds'', but either way, by the time the story ends he has crossed the MoralEventHorizon and is heading on down.
** He killed exactly ''one'' superhero by accident and was visibly horrified. The part where he said it was their fault was clearly denial.
* Designated Hero: The "heroes" of this story look downright ''psychotic''. Where to begin? The Flashes shoving a terrified teenage boy into the Speed Force for what was clearly an accident while ignoring his pleas? "What are you doing!? I said I didn't mean to!" Superboy jovially freeing Black Adam to help them despite the justified doubts of a comrade? Powergirl's non-reaction to a man's head being turned into hamburger meat in front of her? Given the premise, these could've been perfect examples of how dark the heroes of New Earth were becoming if they were ever called for these actions. Despite being one of the supposed true heroes, Kal-L doesn't exactly come off smelling like roses, either. When calling out Diana for how the Justice League are acting completely unheroic, one of the key points he lists is how their League "lobotomizes their adversaries" ignoring that Dr.Light had ''raped'' Elongated Man's ''wife'', and that the lobotimization in question was an accident anyway.(they were attempting to "clean him up") It certainly wasn't the choice a hero makes, but Supes's complete lack of understanding given the situation doesn't speak well of him. One wonders what his response would be if asked [[ArmorPiercingQuestion what he would've done if he had just stumbled upon Lois being brutally raped]].
* MemeticMutation: "Superboy punched [=reality/time/a wall=]" became a popular way to describe {{Asspull}} {{Retcon}}s for a while.
* MoralEventHorizon: Alexander Luthor has crossed it from before the story started and just kept on going. Superboy Prime crosses it at the end by killing [[spoiler: Golden Age Superman]].
** He didn't cross it when he started murdering [[CListFodder lesser known but still actual heroes]] a few issues before that?
*** The first time it was an accident, in a case of DoesNotKnowHisOwnStrength.
** Alex's concrete crossing was probably in the lead-in series ''Villains United'', when he [[spoiler: kills [[TheWoobie Pariah]]]].
* {{Squick}}: Prime [[spoiler:carving his own chest. Wouldn't be so bad, if he didn't look like he had ''rabies'' or something...]]
* TearJerker: The deaths of [[spoiler: BlueBeetle, [[TheGoldenAgeOfComicBooks Golden Age]] Lois Lane, Superboy, and [[TheGoldenAgeOfComicBooks Golden Age]] Superman]].
* TheWoobie: [[TheGoldenAgeOfComicBooks Golden Age Superman]], [[spoiler:especially after his Lois dies.]]
