!!YMMV: Infinite Crisis Comic
* DesignatedHero: 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]]. The overarching, but unintentional, theme of the book is passing judgement without proposing any real solutions.
* 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 towards the middle by murdering [[CListFodder lesser known heroes]] and at the end by killing [[spoiler: Golden Age Superman]].
** 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 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]].
* TheyJustDidntCare: In the second issue, Tempest tells Dolphin to get "their daughter" to safety when the Spectre arrives to destroy Atlantis. Tempest and Dolphin didn't have a daughter, they had a son. This could've just been written off as an editing mistake, but even when the trade paperback collections of the series were released, Tempest's word balloon was never fixed.
** It seems someone at DC finally realized the mistake with the latest trade paperback printings bearing the new DC logo, and Tempest now refers to his and Dolphin's "son" instead of "daughter."
* TheWoobie: [[TheGoldenAgeOfComicBooks Golden Age Superman]], [[spoiler:especially after his Lois dies.]]
