* {{Asspull}}: Deathstroke's victory over a JusticeLeagueOfAmerica team can only be described as a complete and total Ass Pull. Sure, the team of heroes he fought didn't include Batman, Superman, or Wonder Woman (two of whom would barely notice Deathstroke if he attacked them, and the third, Batman, would be ready for him if he did), but it ''did'' include the Flash and Green Lantern, neither of whom was portrayed as actually ''knowing how their own frigging powers worked'' during the fight. It was, in fact, embarrassing. For the writer.
* AuthorsSavingThrow: Dr. Light used to be a serious threat capable of taking on the Justice League, but somewhere along the line became a comical punching bag of the Teen Titans. This mini explains why that change took place and restores him to his original characterization.
* BrokenBase: The Deathstroke vs. Justice League fight. For all that is holy, '''[[InternetBackdraft never]]''' bring it up in any [[PopularityPower Versus Discussion]], less you want the thread to be completely derailed.
** The book itself is a major BaseBreaker.
*** Notably, the book occupies many extremes simultaneously. [[spoiler: Jean Loring claims not to have wanted Sue's death, but brought along a flamethrower anyway, [[SarcasmMode perhaps as a baby shower present.]] On the other hand, Dr. Light's return to form, the upgrade to Calculator, and the rarity of a CrisisCrossover focused more on a personal level than on an apocalypse, were all critically lauded elements.]]
* MemeticMutation: The series inspired a fad on the SomethingAwful forums of user avatars showing their [[WildMassGuessing Wild Mass Guesses]] about the identity of Sue Dibny's murderer. The response to the series played a role in the formation of the "Batman's Shameful Secret" forum for comic book discussion on the site.
* MoralEventHorizon:
** Crossed when [[spoiler: they used Zatanna to alter Dr. Light's personality - which led to them using Zatanna to wipe ''Batman's'' memory.]]
** Not to mention [[spoiler: Dr. Light and the whole, y'know, raping Sue Dibny thing.]]
* OneSceneWonder: Deathstroke, ''and HOW''.
* ShockingSwerve: [[spoiler: Jean Loring being the murderer]] when pretty much ''all'' of the evidence beforehand suggested somebody else.
* VillainSue: Many felt Deathstroke was this during the series, in which he ''solos the Justice League'', including displaying ''faster reflexes than Wally West''.[[note]]Not really. He just predicted ahead of time where Wally would try to attack him.[[/note]]
* TheWoobie: Several, particularly Elongated Man and [[spoiler: Robin]].
