Evil Vs. Evil

This category refers to morally-dubious characters whose main enemies are themselves villains. Obviously, the story needs to have more than one villain (or even amulti-being ordissociative villain with two evil counterparts) for this to be possible. Many extremely dark works, such asWarhammer 40,000, base their main conflicts around this principle, and nearly allProtagonists are portrayed mainly fighting individuals who are either similar to or clearly even worse than they are. However, not every villain who has ever fought another villain should go here. Villains only belong if this applies to most or all of their activities and is a significant aspect of their character and if they are seen as "Heroes" in their setting due to the extreme levels of wickedness committed by their enemies. Some of these villains are also known as "Enemy of a Villain or Villain's Hater".

Good examples of this includeJoseph Stalin andAdolf Hitler,Vegeta andFrieza,Slade andTrigon,Freddy Krueger andJason Voorhees,Mr. Krabs andPlankton (more specifically after the first movie),Kratos andZeus,Alastor andVox,Megatron andStarscream,Fliqpy andTiger General,Tom Cat andJerry Mouse,Ryuga andRago,Spectra Phantom andKing Zenoheld,Wario andBowser,Kazuya Mishima andHeihachi Mishima,Xenomorphs andPredators,Tony Soprano andPhil Leotardo,Trevor Philips andDevin Weston,Megamind andTighten,Rick Sanchez andRick Prime,Risky Boots andPirate Master,Harley Quinn andJoker,Dan andTravis Touchdown,The Beast andGaston LeGume,Kash D. Langford andDaniel Kon,Team Aqua andTeam Magma,Mal andUma,Walter White andGus Fring,Prince Olympius andDiabolico,Gumball Watterson andRob,Donkey Kong andKing K. Rool,Tomura Shigaraki andRe-Destro,Sport andTravis Bickle,Michael Corleone andVito Corleone vsEmilio Barzini,Philip Tattaglia,Carmine Cuneo andVictor Stracci. Void 4 is an example, since he is a noble demon bent on destroying Black Hole and tyrants.Maleficient,Queen Ingrith andKing Stefan fit this trope for most ofMaleficent (and its sequel), as all three are villains who are fighting against each other.Alejandro andHeather from theTotal Drama franchise also fall under this category, as they both have a rivalry during their time in the competition. For the third season of13 Reasons Why,Bryce Walker,Monty de la Cruz,Zach Dempsey,Marcus Cole,Clay Jensen,Justin Foley, and the rest ofThe Bakers Dozen are all examples of this.

Evenvillainous protagonists can qualify if they are (or occasionally) rivals with a villain.GoodExamples:Peter Griffin andCarter Pewterschidmt,Felonious Gru andVector Perkins,Darth Vader andEmperor Palpatine,Ryuga andRago,Megamind andTighten,Jim Carrey Grinch andMayor Augustus Maywho,Venom (Sony's Spider-Man Universe), andRiot (Sony's Spider-Man Universe),Mr. Krabs andPlankton,Heinz Doofenshmirtz andAloyse von Roddenstein,Trevor Philips andSteve Haines,Walter White andGus Fring,Tuco Salamanca.

NOTE: Sometimes after an Evil Vs. Evil battle has ended and a less evil villain defeated the true evildoer, the less evil villain might possiblyreform and become ahero or maybe ananti-villain if they wish, in which case they will NOT qualify asKarma Houdini. In such cases, they involve a more sympathetic villain going up against someone much worse. Although, there are cases ofPure Evil villains who can viciously dispose another villain who is not Pure Evil (if able), and in rarer cases, a Pure Evil villain will take on another Pure Evil villain so this category counts as such. SeePure Evil Vs. Pure Evil.
