* AlternateCharacterInterpretation:
** Slade himself is subject to this a lot. Is he a moral mercenary who just does what he's good at or a completely amoral monster? Does he care for his children or are they just pawns in the games he plays? Depends on who you ask and who's writing him.
** Slade's defeat in Titans East. Was his ultimate goal to try and get the Titans to accept Rose and Jericho so they could give them the family he couldn't? Or was he just lying to himself because he can't handle the idea that his plan fell through again?
* BaseBreaker: Slade's handling by some writers has divided him into three categories. There are fans who still love him, fans who are unhappy with how he and his family have been handled since Identity Crisis, and those who wish he was dead. What has further broken this base was the infamous Titans: Villains for Hire special where he and his team of mercenaries butchered Ryan Choi.
* CantUnhearIt: If you've seen ''WesternAnimation/TeenTitans''. You'll most likely be reading every line in Creator/RonPerlman's very serious voice. Alternatively, fans of ''Series/{{Arrow}}'' probably hear Creator/ManuBennett's voice, which has became equally iconic for the character, albeit for the mercenary versions more than the Chessmaster ones. To a lesser extent, fans of his video game appearances may hear Creator/MarkRolston or J.G. Hertzler from the ''Arkham'' and ''Injustice'' series that prominently featured him. The late Creator/MiguelFerrer's performance in ''WesternAnimation/TeenTitansTheJudasContract'' may very well reach this status as well.
* CompleteMonster: His ''WesternAnimation/TeenTitans'' incarnation and his incarnation from ''WesternAnimation/SonOfBatman'' & ''WesternAnimation/TeenTitansTheJudasContract''. See those pages or see [[Monster/DCAnimation here]].
* DorkAge: The ''Titans: Villains For Hire'' era was one not just for the Titans, but Deathstroke. It was by far the most critically lambasted run of any Titans-related comic and fans hated for how horrible the characters acted (especially Slade orchestrating the gang murder of Ryan Choi) yet were still expected to be sympathetic, plus the stilted writing and horrible artwork.
* MoralEventHorizon: While Slade has done numerous criminal and downright evil deeds, the fact that he orchestrated the deaths of Rose's foster parents just to make sure she had no choice but to start living with him followed by pumping her full of mind altering drugs and turning her into a psychopath should put him over the line.
* NeverLiveItDown:
** He's popular and all, and it's not ''that'' extreme an example... but you will find a lot of people who won't let the character live down sleeping with Terra, a teenager. Although this is usually brought up due to frustrations from the double standards of the situation, and that the other characters will gloss over it while bringing up all the other horrible things Slade's done. The writer's attempts to retcon Terra's behavior as a result of Slade drugging her made the situation look even sketchier than it already was.
** Slade butchering Ryan Choi and delivering the body in a matchbox to Ryan's arch enemy Dwarfstar. The most infuriating thing about it is Slade was never punished for what he did until ''ComicBook/{{Convergence}}'' where he was quickly beaten and humiliated by both Atoms.
