History NightmareFuel / StreetFighter

* The story of Bison's elite assassination squad, the Dolls, is a fucking nightmare. Twelve teenage girls kidnapped by Shadaloo agents from around the world (one of them from T. Hawk's tribe), with their families and relatives never knowing what happened to them, and subjected to heavy brainwashing and experimentation in order to turn them into the perfect killing machines. They have no personalities whatsoever, save for complete devotion and loyalty to Bison. They're even [[PsychicLink mindlinked]] to Bison so that if he dies, they'll die, too. And despite their high success rate, when they manage to locate and capture Ryu for Bison, he rewards them not with promotions or vacations and all that jazz, but by ''[[YouHaveOutlivedYourUsefulness commanding them to die]]'', [[MistreatmentInducedBetrayal which prompts all of them to betray their master]]. But when they're finally freed from Bison's control, they don't even get to enjoy their newfound freedom because their brainwashing goes so deep that they literally can't function without Bison, which crosses into TearJerker territory. And it's widely believed by the fandom that [[MemeticMolester Bison]] might have been [[SexSlave doing a]] [[RapeIsASpecialKindOfEvil lot more]] than just brainwashing those poor girls...

* Some aspects of Dhalsim can be nightmarish. For one, the fact that he wears ''the skulls of children'' as part of a necklace. His official bio says that he does this out of remembrance for the children in his village who died in a plague, but you're not going to know that at first glance. To newcomers, he'll probably appear less "MartialPacifist who fights to save his village" and more like "Jungle tribe cannibal with freaky powers who eats children for breakfast". Second, the fact that a martial artist who looks ''emaciated'' is fighting among muscled and physically healthy opponents. If it weren't for his SupernaturalMartialArts and Richard Reed-esque stretching power, he's gonna get pummeled ''very'' quickly. Third, his establishment as the series' NiceGuy can make his "I will meditate, and then destroy you" victory quote from the original SFII extremely jarring.

* All of the Shadaloo fighters have some frightening aspects, but [[PsychoForHire Vega]] is easily the worst of the lot, seeming more like a slasher villain then a martial artist. Setting aside his mask and vicious claw, the man is a completely ruthless AxCrazy killer who can go from calm, refined (though condescending) conversation to screaming, raging bloodlust over even the slightest contact to his face. Worse, when he's not fighting in tournaments or carrying out Bison's orders, Vega passes his time with ''serial murder''; stalking and killing innocent people [[DisproportionateRetribution whom he deems ugly]] with no SupernaturalMartialArts to protect themselves with. [[VideoGame/StreetFighterV Eventually]], he becomes unhinged to the point that he [[ToThePain openly fantasizes about mutilating his female opponents]] and even expresses a desire to ''[[BloodBath bathe in Chun-Li's blood]]'', ala [[https://en.wikipedia.org/wiki/Elizabeth_B%C3%A1thory Elizabeth Báthory.]]

* Bison's conditioning of Charlie into a monster is done by transforming his body and bombarding him mentally with real-life images of war, pain, and death. No one under his employ except Dhalsim cares, and Bison's plan was to make entire armies of soldiers just like him to conquer the world. Guile's first reaction on seeing him is to try a MercyKill.

* The death of Dan's father Go Hibiki at the hands of Sagat in ''Street Fighter Legends: Chun-Li''. First mentioned in Street Fighter Alpha II, UDON's interpretation shows what happened in its full graphical detail, with every panel detailing everything from Sagat's loss of his eye, to the ''brutal'' NoHoldsBarredBeatDown Sagat dishes out in retaliation.
