History Jerkass / TotalDrama

* Chase is a prankster with zero regard for other people's feelings, even his girlfriend Emma, and is shown to be more selfish than even Courtney.
* At first glance, [[Characters/TotalDramaJulia Julia]] seemed to be like Dawn in terms of personality. Once MK exposes her true self online, she rolls along with it and acts apathetic to her fellow contestants.
* MK is a DeadpanSnarker who is usually cynical and has no problem cheating

* At first glance, Julia seemed to be like Dawn in terms of personality. Once MK exposes her true self online, she rolls along with it and acts apathetic to her fellow contestants.

* Lightning is easy to underestimate while Jo and Scott are around, but there's plenty leading up to him taking over as the series' BigBad once the other two are gone. There's his poor attitude and sometimes aggression towards Sam, using violence (like Jo) to keep his team in the truth challenge in "Truth or Laser Shark", kicking rocks onto Zoey and Mike in "Ice Ice Baby", his deal with Fang to hand him Scott (who'd he'd only known as a capable teammate) in "Grand Chef Auto", and so on. Once Cameron sort of cheats him out of immunity after he'd helped him get rid of Jo, Lightning goes berserk and stays that way for the rest of the season.

* MK is a Deadpan Snarker who is usually cynical and has no problem cheating

* Chase and Emma. Emma spends her energy in torturing Chase and while she acts better with others, her goal in spiting Chase overtakes that side and she grows worse after Chase's elimination. Chase is a prankster with zero regard for other people's feelings, even Emma's, and is shown to be more selfish than even Courtney.

Since this series is a SadistShow, so it's bound to have [[{{Jerkass}} several characters act like this]] every now and then.

* Heather, the resident AlphaBitch of the season 1 cast, is known for being self-centered, vain, hateful, ruthless, manipulative, bullying, and having nothing but condescending contempt towards almost everybody. She read Gwen's diary out loud for the world just because Gwen gave her a little lip. [[EvenEvilHasStandards Even Chris was absolutely disgusted with her for it.]] She does become a somewhat better person in later seasons, but not by very much.

* Courtney is shown to be a SpoiledBrat and an EntitledBitch in ''Action'' when she sues her way into the show and demands blatant advantages handed to her by threatening to sue them further for not "giving her what she deserves". At least Heather did things under her own power and not threaten every little thing not going her way with lawsuits.

* Alejandro, "The Arch Villain" -- a FauxAffablyEvil ManipulativeBastard and BitchInSheepsClothing who will stoop to any level to win. He has seduced girls with little care for how it will hurt their established romantic relationships, hurt and humiliated even the nicest contestants on the show without remorse, feigned friendship and sympathy to others for his own self-gain, and backstabbed those who were legitimately friendly towards him out of pure self-interest. Considering how greedy and self-centered he is, it was little wonder he was seen as the perfect love interest for the equally despicable Heather (and ironically, her shared traits made her the only veteran competitor able to defeat him in the end).

* Duncan can be a JerkWithAHeartOfGold, but his negative qualities are cranked up in the 2nd and 3rd seasons. He has no qualms picking on Harold on a daily basis and acts generally obnoxious, especially towards Courtney.

* Bowie is a ManipulativeBastard who eliminated Caleb just to prove his superiority and drove a wedge in-between Priya and Millie's friendship for his own benefit. [[ALighterShadeOfBlack He's not as bad as most people on the list though]].
