Esdeath from Akame ga Kill! Angel Blade is an erotic anime, so evil will be sexy. Mistress Nailkaizer is especially popular, but you've also got Chloe, Elaine , and the Black Widow from the sequel.
The grand prize, however, is won by the Dark Mother , by far the sexiest thing to ever come out of the Evil Overlord trope and the one bossing around and doing other things to the above four. Claire Stanfield from Baccano! Ax-Crazy Psycho for Hire with a He averts this trope by being a very nice, likeable, though rather goofy guy when he's not conducting business.
Mitsuko Souma and Kazuo Kiriyama, the two main villains of Battle Royale are described as being the two best-looking students in the class. Slan and Griffith are pretty hot, especially considering what most of Berserk 's demons look like.
Rule of thumb in Bleach is, if you're a villain who's not gonky , you're either this or a badass, sometimes both , with copious amounts of skin showing being a must.
Here's a small list: Packing a six pack on top of exposing most of his chest and torso? Badass Baritone and sexy blue hair? The most stripperiffic resurreccion getup possible?
Busty chest, curvy figure, attractive voice when she's speaking calmly , and whip-toting , with a dominating personality. Sosuke Aizen, post-reveal as the Big Bad ; ain't a single fan who hasn't commented on his new sexy hairdo.
Bambietta Basterbine, just Bambietta Basterbine: She's even aware of this as she screws a random soldier and kills him once she bangs him silly. Candice Catnipp doesn't trail behind Bambietta, either; her Hot-Blooded attitude when fighting, coupled with the shameless closeups of her skimpy uniform, makes it all the more eye-candy.
Ironically enough, Gin has plenty of fangirls, even though Kubo designed him to be creepy and offputting. Although neither of them is the real main antagonist. Aion from Chrono Crusade plays with this, particularly in the anime adaptation, where he goes from being attractive and charismatic to willing to sleep with Anything That Moves.
However, this trope is also used in the anime to make him creepy and squicky — he not only happily seduces those that are willing to sleep with them, but is implied to attempt to rape many of the ones that aren't willing and may have even succeeded in one case.
Light Yagami from Death Note is much hotter when evil than when innocent. Date A Live has its entire premise revolving around the main character trying to tame attractive supernatural entities by dating them, but while most of them start out as antagonistic, they're usually not fully evil.
However, the introduction of Deus Ex Machina Industries plays this completely straight, as Big Bad Isaac Westcott, his fanatically loyal Dragon Ellen Mira Mathers, and heck all the female operatives in general, are absolutely villainous and quite easy on the eyes.
Oddly averted in their comically round but nonetheless badass leader, The Millennium Earl, but as of chapter he plays this straight with his human form.
Indeed, LadyDevimon was probably thrown into Digimon Adventure as a Monster of the Week just to invoke this, being that she promptly gets into a Cat Fight with Angewomon. Also of note is Archnemon at least in human form; her spider form, not so much , and Ranamon until she slide-evolves into Calmaramon. The ladies get Beelzemon , who's very blonde , has a husky voice, and wears spiky armor, tight leather pants , and a very clingy shirt that may as well have been spray-painted onto his very defined abs.
The "evil" part is subverted, however. In-universe, General Blue and Zarbon , who Bulma crushes on. Though Zarbon loses this when he transforms. Not only does he have Son Goku's body, he has it in slimmer proportions and his Creepy Monotone voice sounds sexy for some people.
In the interview for the fouth volume for the manga, Toyotaro does talk about Toei Animation receiving letters from many people finding Black's voice sexy. Many of the humanoid Eclipse Celestial Spirits are getting this reaction, too. Of course, considering that the heroes are sexy as well, this shouldn't be surprising. She isn't lustful, she's a lust item herself. Greed, who is introduced with two attractive women hanging on either arm.
Sloth in the the anime version is just as good-looking as Lust, though admittedly she doesn't ooze sex appeal. However, its raspy voice , many Kick the Dog moments, association with horrific shapeshifting, and its pitiful, fetus-like true form makes Envy too frightening and disturbing to be viewed sexually.
Guess which side she's on. Daisuke, one of the show's two heroes, is fairly decent-looking in ways that don't really inspire lust, being a rather pretty young man with clothes that cover most of his body. By contrast, his enemy Clair Leonelli wears tight-fitting leather pants and a slinky purple shirt that opens all the way down his chest. There's also Daisuke's Knight Templar Big Brother Shun, who's much prettier than Daisuke himself and seems to be an object of desire for most women he encounters.
He even shares a voice actor with Zagato above! Alucard from Hellsing essentially orgasms from ripping people into pieces and has consumed approximately four million souls over his centuries of existence, and still manages to be the sexiest character on the show, taking Creepy Awesome into fetish territory. Alucard may be more amoral than downright heartless because he does remain loyal to the Hellsing Organization. He took his shirt off during his grand battle scene.
Quite a few manga artists like to play up how sexy Miyo Takano of Higurashi: When They Cry is, though she's already quite sexy once you get past her standard expression. Dakki, the Big Bad of Soul Hunter. She's well-formed, and often wears revealing outfits. Her magic weapon even gets a power boost when she strikes sexy poses.
Inazuma Eleven Most of the antagonistic teams in season 2 wear skin-tight uniforms and the members are pretty attractive unless they're a Gonk. One notable example is Dark Emperor Kazemaru, whose Evil Makeover made him even more attractive for the fangirls. He's named after the goddess of beauty after all. Kagura and Yura of the Demon Hair are also pretty sexy in their own right.
While not strictly speaking evil, Sesshomaru definitely counts. Naraku in his Kagewaki guise, at least when his body is not made up of a bunch of demon parts. Many of his subordinates follow him just because of his charisma and beauty. Many of them of both genders outright wanna jump his bones , and some succeed Vanilla Ice and Enrico Pucci. To be slightly fair however, he was already extremely attractive BEFORE he became completely evil, and its implied that he is using his Stand Power to aid him in this.
Dio's beauty is so amazingly mythical leveled that it even seduced a blind man. To many fans of Kill la Kill , Ragyo Kiryuin plays this trope perfectly. Satsuki and Nonon before they're revealed to be protagonists are also this. In the first season , main protagonist Nanoha wears a white schoolgirl uniform with a long white skirt and long white sleeves, a costume that's cute but conservative.
The main antagonist Fate wears a black swimsuit with very interestingly placed red belts and a pink skirt that's barely there, a costume that's sin incarnate.
When panty shots are applied, Nanoha's are pink, while Fate's are black save for that one instance with the pink thong. However, after she's switches sides she retains the outfit, and in later seasons it becomes more Stripperiffic. It runs in the family. Fate's Non-Human Sidekick , Arf, is blessed with the Most Common Super Power while wearing a Stripperiffic halter top with a bare midriff and a pair of short shorts that's unbuttoned and sometimes look like they're not zippered either, while Fate's mother is Precia Testarossa.
Force continues the tradition with Arnage of Huckebein, an Evil Redhead with bared midriff , nice rack and hotpants, as well as her teammate Curren who wears a fancy sports bra thing she fills out well along with shorts.
