Infinite Crisis/YMMV
- Complete Monster: Alexander Luthor has definitely become this here.
- Fixer Sue: Superboy-Prime is a Deconstruction. He's someone who has a way he wants the universe to be, power enough to make it be that way... and the personality of the average sort of person who writes Fixer Sue fanfiction. Naturally, a lot of fans weren't amused at what they saw as a personal attack.
- Memetic Mutation: "Superboy punched reality" became a popular way to describe Ass Pull Retcons for a while.
- Moral Event Horizon: Alexander Luthor has crossed it from before the story started and just kept on going. Superboy Prime crosses it at the end by killing Golden Age Superman.
- Alex's concrete crossing was probably in the lead-in series Villains United, when he kills Pariah.
- Squick: Prime carving his own chest. Wouldn't be so bad, if he didn't look like he had rabies or something...
- Tear Jerker: The deaths of Blue Beetle, Golden Age Lois Lane, Superboy, and Golden Age Superman.
- Unfortunate Implications: You'll often hear claims that Phantom Lady's death smacked of misogyny, as she ends up Impaled with Extreme Prejudice on a long, thin object... right between the breasts!
