* 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: While he still remains something of an EnsembleDarkhorse, 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 ''ComicBook/IdentityCrisis'', and those who see him as a VillainSue and 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 Manu Bennett'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 Mark Rolston or J.G. Hertzler from the ''Arkham'' and ''Injustice'' series that prominently featured him. The late Miguel Ferrer's performance in ''WesternAnimation/TeenTitansTheJudasContract'' may very well reach this status as well.
* EnsembleDarkhorse: He's become a fan-favorite villain of the DC Universe.
** This goes for other DC media outside of comics. Ironically, the character's first mainstream exposure that contributed to his growth in popularity was in the ''WesternAnimation/TeenTitans'' animated series that was made at a time where stricter network censorship made the show [[NeverSayDie unable to use his alias]], which is why he was simply called "Slade" instead, but every incarnation of the character to appear in other media since then has been called Deathstroke.
* 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.
