Evil Costume Switches in Western Animation.
- Justice League: The "Justice Lords", Alternate Universe Knight Templar versions of the Justice League from "A Better World", all wear redesigned costumes with much more black and monochrome — except for Justice Lord Superman, that is, whose costume was mostly white, reflecting his more black-and-white view of morality than "our" Superman. Note that Wonder Woman's famously Stripperiffic outfit becomes extraordinarily conservative for her evil version, either inverting Sensible Heroes, Skimpy Villains or reflecting the moralizing Knight Templar philosophy. Batman's outfit is also slightly brighter and boasts a silvery sheen, as this one no longer operates in the shadows (Gotham under the Justice Lord's reign is a bright, pristine police state).
- Happens on several occasions in Codename: Kids Next Door:
- In "Operation: D.A.T.E.", the Sector V operatives are invited to a party by their sworn enemies, the Delightful Children from Down the Lane, and Numbuh One decides to use the invitation as a reconnaissance mission, believing that the party is a trap. His suspicions are ultimately confirmed when he sees the guests, including his teammates, brainwashed and delightfulized, with their regular partywear being replaced by the typical attire worn by the Delightful Children. However, thanks to Lizzie, who served as Numbuh One's date, flashing a camera on those who were delightfulized, their personalities and clothing return to normal.
- In "Operation: L.O.C.K.D.O.W.N.", Numbuhs One, Two, Three, and Four and Numbuh Three's Big-Bottom Rainbow Monkey Doll are transformed into Spank-Happy Vampires. Sticking to the vampire stereotype, all are given pale skin, tuxes for the guys and dresses with jagged hems for the girls (Numbuh One's tux is black, both Numbuh Two and Four's tuxes are blue and Numbuh Three's dress is black), leggings (Numbuhs One and Two's are both black, Numbuh Three's are purple and Numbuh Four's are white) Pointy Ears, sharp fangs, the typical Transylvanian accent and the slicked back hair for the guys and Messy Hair for the girls (in this case, Numbuh Three), whereas Numbuh One had no hair to begin with and Numbuh Two wears his flight helmet and goggles, which are stretched out in triangles for an angry appearance, all the time. Also included are the gloves (Numbuh One's are white, Numbuh Two's are blue and Numbuh Four's are orange, whereas Numbuh 3 retains the long sleeves from her usual outfit, only they're also jagged), the batwing capes (the boys' capes are red and Numbuh Three's is pink) and the medallions all having their numbers shown (both Numbuh One and Three's are purple, Numbuh Two's is golden yellow and Numbuh Four's is orange). How a Spank-Happy Vampire can turn their victims into vampires is by spanking the victim without his/her gloves rather than biting them like the traditional vampire, and the only way the victim can reverse this process is by spanking back the vampire who spanked them, or spank the original Spank-Happy Vampire, Count Spankulot himself. Numbuh One was spanked by Count Spankulot by being lured out of bed into his jail cell at night, then when the lockdown commenced, he faked his injury from the R.O.A.D.S.T.A.R. crash, waiting to strike and spread his vampirism to the others after they had broken some rule during the lockdown: Numbuh Three and her Big-Bottom Rainbow Monkey doll for sleeping through the alarm and Numbuhs Two and Four for leaving the Med Lab after they were told not to (Two to get a snack, and Four to convince Numbuh Five to use the Quadruple Emergency Bypass Code to lift the lockdown). In this episode, Numbuh Five narrowly avoided the transformation for using the Quadruple Emergency Bypass Code, but she wouldn't be so lucky in Operation: V.I.D.E.O.G.A.M.E., and that time around, Numbuh Four would be the only operative spared from being spanked.
- In that same episode, The Evil Makeover given to Numbuh Three's Big Bottom Rainbow Monkey Doll, called "Big Bottom Vampire Monkey" when transformed, includes a jagged discolored rainbow (pink, purple and red) on its head, a jagged belly, spiky tail, a vampire's high collar and its classic Mickey Mouse eyes are replaced with glowing evil red eyes. The doll, as well as its owner, who slept through the alarm, were the first victims to be spanked when the lockdown of the treehouse began, as noted by its bottom being ripped and the stuffing falling out.
- Numbuh Three is given a volcanic transformation in "Operation: H.O.T.S.T.U.F.F." when she turns up the thermostat at her house, causing it to transform into a volcano about to erupt: her nightdress is burned up with the sleeves going up to her elbows and the hem of the shirt going up to the bellybutton, her pajama pants are reduced to shorts, her slippers resemble volcanic demons, her green blanket has become a cape and she gains fiery hair and eyes. It is after her teammates turn down the thermostat and get the house back to normal does she return to normal. Who knows what's become of Mr. Sanban when he turned down the thermostat in the treehouse while staying there during this incident...
- Used extensively in Teen Titans (2003):
- Robin: when he dons the Red X costume in order to catch Slade, entering Knight Templar territory. And again, when he becomes Slade's apprentice, wearing another black costume with armor plates and a spikier mask.
- Raven always wears the dark leotard-under-cloak costume in the series, but once she is briefly seen with a red cloak and the four eyes of Trigon - never a good sign. This one shows up again in the comic; a red-skinned Raven is seen when she's under the influence of her demonic father, and a white-cloaked version appears after she's purified of said influence. Inverted when Malchior is teaching Raven dark magic, whereby Raven's robes turn white.
- When Cyborg goes undercover in the Villain School, he designs a "villain" costume for the occasion, along with his disguise (as himself without cybernetics): himself with rock skin.
- The rather late origin story episode featured Starfire with a much blacker, more armored costume (identical to the one worn by her sister, Blackfire), along with an alien and less-than-girly princess crown. She was a villain for about half the episode, during which she was very badass.
- Beast Boy...doesn't actually get an evil costume, unless you count his shapeshifting into The Beast, then yes, all the Titans had an Evil Costume at some point or another.
- Terra also gets an evil costume switch or, rather, two. The first time we see her, she's wearing a fairly normal-looking outfit. Then, when she leaves and returns later, she's wearing a cooler, but out-of-character, black outfit. Then, when she becomes overtly evil, she gets this much uglier, metallic-looking body armor.
- Kim Possible:
- When the HenchCo made Mood Reverser was accidentally used on Ron, he simply continued to wear a fictional villain's costume for the rest of the episode, and while said villain outfit was, in fact, quite lame, his regular clothes turned to a Fonzie-style badass look. Also, his skin turned blue as a result of getting an infusion of blue-skinned Dr. Drakken's evil, while Drakken's reverted to pink flesh tone.
- During the second appearance of the Mood Reversal device, there wasn't any costume switching. However, when a person was hit, they would glow Red for evil or Blue for good. The only real change that could be noticed was that evil was less cowardly and Ron Stoppable was competent.
- Shego began dressing in a Teacher uniform after being hit by the Moodulator. Good Costume Switch?
- Averted with the Face–Heel Turn in Shego's backstory; her current costume is the same one she wore when she was part of Team Go.
- When Drakken manages to put Kim under Mind Control, she wears one of Shego's outfits.
- The Venture Bros.:
- Professor Impossible makes the switch following his Face–Heel Turn with Phantom Limb.
- Although technically always a villain as soon as Henchman 21 stopped being a Minion with an F in Evil he changed his humorously nonthreatening costume for one with ripped sleeves and a retractable knife.
- Dr. Henry Killinger made Rusty a new costume during his failed attempt to turn him into a villain.
- In South Park, Butters adopts the name Professor Chaos and a costume when he wishes to do evil.
- The Spectacular Spiderman:
- Doctor Octopus' first battle against Spider-Man is fought in the civvies he wore during his Freak Lab Accident. The fight is soon cut short when his tentacles run out of power. He plans to get another, longer-lasting power source, but when he next confronts Spidey, he's also undergone quite the Evil Makeover, having donned a Badass Longcoat and replaced his Nerd Glasses with equally badass Cool Shades (eschewing the usual goggles derived from the comics).
- As mentioned under Comics, Spider-Man himself with the symbiote. In an interesting twist, in this series, it starts out as just his normal suit in black (a la Spider-Man 3). As the symbiote asserts more control, it starts looking more and more like his classic black suit.
- Avatar: The Last Airbender:
- Done straight, then reversed. For all of Season 1, Zuko wore fairly standard villain wear for the show. Lots of militaristic red, Shoulders of Doom, the whole enchilada. Season 2 had him "on the fence", so he wore mostly nondescript clothes, in the greens and browns of the Earth Kingdom, whose members we had seen both as heroes and villains. After his subverted Heel–Face Turn in the season finale, we see him wear the full black-and-red military garb of Fire Nation royalty, the same as Azula. After he has a real Heel–Face Turn for real, he gets a red-and-gold costume that isn't nearly so intimidating...though it still looks cool.
- Also, Ozai in the finale, kind of. He switches to more regal looking robes when he declares himself Phoenix King and goes off to obliterate the Earth Kingdom. In this case, it's more of an Eviler Costume Switch.
- Code Lyoko: after being possessed by XANA and falling in the Digital Sea, William gains a fully evil (and skintight) costume of black and red spandex with what is sometimes described as a corset (maybe to symbolize his servitude to XANA). His sword also gets a full change, with a prominent Eye of XANA and evil-looking black veins all over.
- Danny Phantom:
- Danny in the evil future. The costume change, however, comes some time after becoming a Fallen Hero. Lesson to villains everywhere: don't ever remove your archrival's emotions/humanity. Girls just love that hypnotic voice of his, though.
- Sam also gets not one, but two evil costumes. One is a rather Stripperiffic Poison Ivy-ish affair, the other very elegant. Her voice work during it is very much Azula.
- Although his good civilian clothes are only shown in flashbacks, Vlad also gets one. He was a geek in college, now he's a suave debonaire billionaire in a fancy black suit.
- The Fairly OddParents!:
- One episode had Timmy wishing to do the opposite of whatever his parents tell him to do in order to escape their overbearing nature. Unfortunately, they tell him to "be good", which immediately transforms him into a sinister villain with a long black cloak, classic top hat, and an evil glint in his eye.
- In yet another episode, when Golden Locks, the Crimson Chin's fiance, transformed into Hair Razor as a result of Timmy's wish, she goes from wearing a short dress to becoming a leather-clad bitch.
- In Gargoyles, when Elisa went undercover to infiltrate Dracon's protection racket, she changed into a low-cut belly top and leather jacket and trousers to seem more criminal-like.
- Princess Jasmine gets one of these in Aladdin: The Series, thanks to Abys Mal and a flower that causes Laser-Guided Amnesia. In her new identity as "The Scourge of the Desert", she wears a dark-blue version of her usual clothes, a hooded cape, her hair in a ponytail (just like how she wore it when she was Jafar's slave in the original movie), and wields a whip. Interestingly, after getting her memory back, she keeps the outfit (and the whip), wearing it as a Spy Cat Suit when Aladdin & Co. infiltrate Mozenrath's city.
- SpongeBob SquarePants: When Barnacle Boy turns to The Dark Side, he gains a villainous cape and his overall appearance grows darker.
- When Shockwave from Transformers: Animated is still disguised as Longarm Prime, he is mostly colored blue and gray, but when all of the Autobots find out that Longarm is actually Shockwave, he actually changes to purple and white (the same colors as G1 Shockwave) to show that he is indeed a Decepticon.
- From the same show, the Constructicons go from more neutral colors (pale yellow and grey) to their G1 colors (neon green and purple) after they are branded as Decepticons. Their personalities don't really change, however. They've just chosen a different playing field.
- Happens quite a bit in Beast Wars, along with Good Costume Switch.
- When Megatron made Rhinox into a Predacon, his brown hide turned purple and the gold plating turned silver.
- Subverted in the first episode when Dinobot goes from being a Predacon to a Maximal, then played straight a couple of seasons later when Megatron resurrects him as a Predacon, though justified since Megatron is using Transmetal technology.
- Justified in season 3 when Black Arachnia turns from Predacon to Maximal due to the Transmetal driver.
- When Grune from Thunder Cats 2011 reveals himself to be a traitor, he discards his Thunderian armor and dons gold raiments emblazoned with the symbol of Mumm-Ra.
- Jane Porter has actually dressed as Queen La at least twice in The Legend of Tarzan when La turned her evil.
- Young Justice (2010):
- When Aqualad fakes a Face–Heel Turn, he trades his red and blue swimsuit for a suit of black Powered Armor.
- Artemis dons one as Tigress (a reference to her villainous comic book counterpart) when she fakes her death and becomes The Mole alongside Aqualad. Her outfit consists of a dark orange and black armored bodysuit and a mask. A glamour charm from Zatanna makes her look like a brunette. Subverted in the finale, as Artemis decides to continue being Tigress as a hero, albeit with her natural hair color.
- When Omi briefly turned evil in Xiaolin Showdown, his robes turned black with red trim and belt.
- TRON: Uprising demonstrates this retroactively with Paige, a medic turned elite soldier. As a medic, she had green Tron Lines and wore a common civilian gridsuit with long sleeves and low-heel boots. As a soldier, her shoulders are exposed and she has Combat Stilettos, in addition to the recolored red Tron Lines. We also see that Dyson kept his soldier's attire, but his lines changed from User-loyal white to User-hostile orange-red.
- An episode of The Powerpuff Girls (1998) has Bubbles take a brief Face–Heel Turn after losing her memory and believing herself to be Mojo Jojo. She promptly heads to his lair, steals his clothes while he's showering, and wears them for the rest of the episode.
- Dexter's Laboratory played with this a bit. In the first few seasons, Mandark was a fairly serious threat, but dressed like a typical non-threatening nerd; after suffering Villain Decay later on, he became a Card-Carrying Villain and started wearing a screamingly obvious black-and-red cape to prove it.
- Metalocalypse: Toki goes all dark and evil, forsaking his childlike ways, and to illustrate the point, wears blood and lots of big spikes.
- My Little Pony: Friendship Is Magic:
- Trixie dons a dark cloak in lieu of her purple magician's costume when she obtains the Alicorn Amulet, which turns her crazy and evil. Once the protagonists remove it from her, she eventually returns to her usual costume and personality.
- Way before that, Princess Luna swapped her crown and necklace for slightly dominatrix-y armor as part of becoming Nightmare Moon. She also turns her coat black and makes herself the size of her sister.
- Ninjago:
- When Cyrus Borg is under the Overlord’s control, he ditches his gray jacket, his hair gets messier, his torso and half his face are covered in wires and metal sheets, and the lights on his cool chair even change from green to red. Similarly, when the same thing happens to Sensei Wu, he gets a new outfit with black and purple accents and a silver conical hat.
- When Lloyd is possessed by Morro, his ninja suit inexplicably changes, becoming more tattered, with more of an emphasis on black and a darker color of green.
- Before revealing her true intentions, Harumi wears green overalls, a dark green hoodie, and has her hair in a cute style. After she’s revealed as a villain, she wears a black leather outfit with a dark blue trim and spikes running up the break line of her jacket, lets her hair down, ditches her lipstick, and wears red war paint to complete her evil makeover.
- As the Brainwashed and Crazy Ice Emperor, Zane puts on silver samurai armor with sharp icicles growing off it, and a muzzle-like mask. Vex undergoes a similar outfit change some point after becoming his advisor.
- Despite every Oni we’ve seen being black in color, Lloyd’s Oni Form actually goes even heavier on gold than his regular outfit. His eyes and powers, meanwhile, go from green to purple.
- In Trollz, the brainwashed heroines' costumes are actually less revealing than their normal outfits, being more like MIB suits.
- "Turf Wars", the last episode of the 2006 revival of Biker Mice from Mars, had Vinnie's old girlfriend Harley, who sided with the Nomad Rats because of the mistaken belief that the Biker Mice abandoned her, doing this. She trades in her beige coat, green shirt, and green pants for black tights and a purple mask to hide the scars she sustained during the Plutarkian invasion.
- The Ice Dancers in Total Drama Presents: The Ridonculous Race swap their purple outfits for black ones for one episode when they decide to become villains.
- In the Donald Duck cartoon "Donald's Crime", Donald adopts a black coat and hat when he starts imagining himself as a criminal.
- Two characters in Rick and Morty have done this.
- When we first meet President/Evil Morty, he's wearing a normal business suit and tie. When he has power and eliminates the Shadow Council of Ricks, he's donned a black suit with red tie.
- After the reveal that Summer's classmate Tammy is a spy working for the Galactic Federation, when next we see her, she is dressed in a sexy black uniform.
- At the end of the DuckTales (2017) episode "The Duck Knight Returns!", after he escapes into the sewers, the purple dye in Jim Starling's Darkwing Duck costume bleeds out, making it a combination of yellow and red and solidifying his Sanity Slippage and transformation into Negaduck.
- All akuma victims in Miraculous Ladybug get an evil makeover, but this trope applies to those who are akumatized while wielding a Miraculous: Queen Bee's predominantly yellow costume with black stripes is inverted to yellow on black as Queen Wasp; Rena Rouge and Carapace are (like all of Scarlet Moth's victims) turned red as Rena Rage and Shell Shock; and Chat Noir becomes the white-clad Chat Blanc.
- Star Wars: The Bad Batch: After Order 66 goes out and the Republic officially becomes the tyrannical dictatorship that is the Empire, Crosshair and Cody switch to wearing grey, Stormtrooper-esque armor to accompany their Face–Heel Turn alongside it. It's subverted in Cody's case, however, as he quickly defects upon realizing how evil the Empire is.
