In many cultures, before the invention of toilet paper and forks, the right hand [[note]]aka "dexter"[[/note]] was used for eating, greeting, etc., while the left hand was used for wiping and other less savory things. In some places, being left-dominant was a sign that there was something inherently 'wrong' with the child, to the point of demonic possession, and to this day [[AbusiveParents some parents]] will tie a left-handed child's hand behind their back until they learn to be ambidextrous. Ironically this will not change the hand that you instinctively lead with in your daily interactions.

* In the infamous "potato chip" scene in ''Manga/DeathNote'', Light, who is being monitored by camera, is shown solving math problems with his right hand while his left hand writes names into a piece of the Death Note he hid in a potato chip bag. It has been [[{{Fanon}} theorized]] that he actually is left-handed, but was taught to use his right as per cultural norms.

* Literature/{{Kane}} is naturally left-handed, which helps him in combat, although he has trained himself to [[HeroicAmbidexterity use his right hand equally profficiently]], which helps him even more. He is also the world's [[CainAndAbel first murderer]].

* Downplayed in ''Franchise/TheKingOfFighters'': yes, Nameless uses his left hand for both wearing his PowerLimiter and to unleash his pyrokinetic abilities. Yes, he is a [[NebulousEvilOrganisation NESTS]] lapdog. But compared to his peers (especially [[EvilCounterpart K9999]]) and superiors, he's one of [[TokenGoodTeammate the noblest members]] of the lot.

* Wrath of ''Anime/FullmetalAlchemist'' may or may not be left-handed, but he got the right one from someone else. The same could be said of Scar, though their alignments turn in opposite directions.

* Dyne, a side-villain in ''VideoGame/FinalFantasyVII'', had his crippled LEFT arm replaced with a machine gun, and is distinctly portrayed as a serial killing lunatic. The reverse is true of Barret - even though he leads a terrorist organisation that blows up a power plant and kills hundreds of people, his RIGHT hand was the one replaced with a similar weapon. He turns out to be a nice, but misguided person who is a doting father and dedicated friend.
** Sephiroth and his remnants are also lefties.
** Aside from Kain the only other left-handed characters in ''VideoGame/FinalFantasyIV'' were Golbez, the main villain, and Palom, who while not evil or villainous was still a bit of a [[BrattyHalfPint brat with a bad attitude]].

* Inverted in the ''Literature/{{Goosebumps}}'' book ''Let's Get Invisible''. The narrator's brother is left-handed, so seeing "him" pitch a baseball right-handed clues in the narrator that he's been replaced by his evil reflection.

* ''VideoGame/LeagueOfLegends'' has [[FallenAngel Morgana the Fallen]], a LadyOfBlackMagic who -- [[DarkIsNotEvil while not strictly "evil"]] -- has a wicked appearance and casts shadowfire magic most predominantly from her left hand. This puts her [[PolarOppositeTwins in deliberate contrast to her angelic twin sister]], [[ThePaladin Kayle the Righteous]], who wields a holy sword in her right hand. It's especially notable considering this is only true following [[ArtEvolution their 2019 redesigns]] -- prior to the update, Kayle was lefthanded while Morgana didn't display a dominant hand, suggesting their current animations were done as [[RuleOfSymbolism very deliberate symbolism]].

* In ''VideoGame/FridayNightFunkin'', Daddy Dearest, Senpai, and [[{{WebAnimation/Tankmen}} Sergeant John Captain, AKA Tankman]] each hold the microphone in their left hand. In Senpai's case, it serves as {{Foreshadowing}} of his BitchInSheepsClothing personality [[spoiler: And Spirit hiding in his coding]].

* In ''VideoGame/FridayNightFunkin'', Daddy Dearest and Senpai both hold the microphone in their left hand. In Senpai's case, it serves as {{Foreshadowing}} of his BitchInSheepsClothing personality [[spoiler: And Spirit hiding in his coding]].

* In ''Series/{{V|1983}}'', whenever a human is [[MoreThanMindControl converted to the villains' cause]], it causes a brain-dominance switch. Since ThereAreNoLefties in TV Land, this leads to left-handed human collaborators.

* ''Webcomic/{{Narbonic}}'': Caliban is left-handed.

* Serial killers Jack the Ripper was alleged to have been left-handed, Theodor "Ted" Robert Bundy was left-handed, the same can be applied to Albert DeSalvo, AKA the Boston Strangler. [[https://www.ranker.com/list/left-handed-criminals/ranker-crime In other aspects]], criminals such as Osama bin Laden, Japanese Prime Minister and war criminal Hideki Tojo, and Public enemy John Dillinger were also left-handed.

* Gin from ''Manga/DetectiveConan'' is left-handed. Also, there is a case Conan solves by realizing a man had been replaced by a duplicate because the fake was left-handed and the original was not.

* In ''Manga/TokyoGhoul'', [[spoiler:the novelist Sen Takatsuki/Eto Yoshimura]] is left-handed and is eventually revealed to be a major villain of the series as the real One-Eyed Owl and the leader of Aogiri Tree. Downplayed in the sequel, however, as while she is vicious and amoral, [[spoiler: all her actions are geared to destroy the BiggerBad of the series.]]

* In ''Manga/TokyoGhoul'', [[spoiler:the novelist Sen Takatsuki/Eto Yoshimura]] is left-handed and is eventually revealed to be a major villain of the series as the real One-Eyed Owl and the leader of Aogiri Tree.

* [[spoiler:Goro Akechi]] from ''VideoGame/Persona5'' is left-handed. Naturally, he's a villain [[spoiler:and the traitor among the main characters]]. Possibly an invoked trope, as the game heavily homages "Classy" works such as Literature/ArseneLupin, SherlockHolmes, Carmen, Literature/TheThreeMusketeers, (etc) where this trope cropped up.
