* ''ComicBook/SpiderMan'': Peter Parker/Spider-Man. While he's a goofy and [[NiceGuy nice guy]] most of the time, when people near and dear to his heart are hurt, a darker persona of his called "The Spider" will emerge. He will then proceed to pummel anyone responsible into a [[NoHoldsBarredBeatdown bloody pulp]] [[TranquilFury while not]] [[BewareTheQuietOnes saying a single word]]. Even his allies have a hard time calming him down and find this side of him downright terrifying. Examples of this include ''ComicBook/TheDeathOfJeanDeWolff'', ''The Grim Hunt'', and ''Back in Black''. He also really likes beating up bad guys.

* ''ComicBook/UltimateXMen2002'': Rogue once borrowed Jean Grey's powers to incapacitate Iceman by making the poor boy mentally and physically re-experience a memory of him going through the surgical removal of his appendix. This time without the anesthetic. Considering she could have simply willed him unconscious, shows a considerable level of cruelty on her end. Being both BlessedWithSuck with powers that do not allow any human contact, and being tortured in a concentration camp can do that to people.

* Characters/{{Harley Quinn|TheCharacter}}, a CanonImmigrant from ''WesternAnimation/BatmanTheAnimatedSeries''. Easily one of the most adorable rogues on the series. Also likes to pummel people and shoot at them for fun.
* Terra I from the 1980s "[[ComicBook/TheJudasContract Judas Contract]]" arc of [[ComicBook/TeenTitans The New Teen Titans]]. Seems like a sweet young girl but is actually a vicious and ruthless mercenary with distinct {{yandere}} traits -- she's not only sleeping with the much older [[Characters/{{Deathstroke}} mercenary/assassin who hired her]], she ends up killing herself (while trying to kill him) when new Titan Jericho [[BodySurf possessed the assassin]] (who just happened to be his father) and freed the Teen Titans, making Terra believe that her lover betrayed her.
* Characters/ScarletWitch is a notably attractive woman with a history of suitors and admirers, but she also has a history of psychosis due to her traumatic life experiences which are exacerbated by [[RealityWarper her powers]] that [[WithGreatPowerComesGreatInsanity deteriorate her mental state at their peak]]. She is primarily responsible for the events in ''ComicBook/AvengersDisassembled'' and ''ComicBook/HouseOfM'', which respectively caused the downfall of her team and 90% of mutantkind being depowered around the world. The fact she was considered the nicest person on the team made it hard for her teammates to believe her actions.
* Rosy the Rascal from ''ComicBook/SonicTheHedgehogArchieComics''. She looks exactly like Classic Amy, but she's AxCrazy and [[PsychopathicManchild has the mind of a child]].

* The closest AlternateCompanyEquivalent to Harley Quinn that Creator/{{Marvel|Comics}} has is Gwen Poole, aka ''Comicbook/TheUnbelievableGwenpool''. She is adorable, sweet, cheerful, a [[TheKnightsWhoSaySquee hyper-fangirl of everything]]... but she happens to have a backstory reminiscent of Superboy-Prime's, which means she thinks all of this is fiction, so for example nameless extras are expendable in the name of the story of the hero (namely [[ItsAllAboutMe herself]]) and comic book death is very cheap too so why ''shouldn't'' she just murder (shoot, blow up, cut to pieces, etc.) the people in her way? This attitude changes dramatically over time, however, as part of her CharacterDevelopment. and she becomes much less casual about apparently random people dying.
* ''ComicBook/UltimateXMen'': Rogue once borrowed Jean Grey's powers to incapacitate Iceman by making the poor boy mentally and physically re-experience a memory of him going through the surgical removal of his appendix. This time without the anesthetic. Considering she could have simply willed him unconscious, shows a considerable level of cruelty on her end. Being both BlessedWithSuck with powers that do not allow any human contact, and being tortured in a concentration camp can do that to people.
