History YMMV / EmperorJoker

* AssPull: ''How'' exactly the Joker scammed Mxy out of his [[IKnowYourTrueName "secret imp name"]] is glossed over, to say nothing of how he (a largely Gotham-bound criminal whose interactions with Superman's wheelhouse are occasional at best) would even know about such a mechanic in the first place. Indeed, the very idea of fifth-dimensional imps having this weakness was something never even implied before (or since) to readers.[[note]]Notably, the ''WesternAnimation/BatmanTheBraveAndTheBold'' adaptation streamlined this into Bat-Mite ''looking'' to give all his powers... to Batman. [[OhCrap And being a crappy shot]].[[/note]]

* CrossesTheLineTwice: The whole storyline is chock full of these moments. One of the best is probably the Joker playing poker with the corpses of all three (at the time) Robins, or him deciding to get Chinese Food, which means him eating all 1.3 billion chinese people.

* HarsherInHindsight: Late in the story Joker tries to break Superman by getting him to accidentally kill all his friends and loved ones, attempting to push Superman to the point of wanting to kill him in retaliation. While he fails here, [[VideoGame/InjusticeGodsAmongUs over a decade later]] we would see what would happen when Joker pulled a similar tactic and it ''did'' break Superman enough to kill the Joker, with the [[FallenHero end results]] [[KnightTemplar as messy]] [[WoobieDestroyerOfWorlds as you think]].
