This technically has a justification, or at least works as a blunt metaphor, since Satan is supposed to be a cunning seducer, and being physically attractive would be a legitimate tactic in this case. The Bible even says that Satan will sometimes appear as "an angel of light".
Trickster gods in some mythologies are able to take whatever form they wish. Trickster gods are not always evil, but can be, and certainly aren't averse to taking on an attractive form (even if it means changing sex) just to mess with the heads of others. If their form is tailored to suit the precise tastes of whoever they're trying to pull, they're a Shapeshifting Seducer.
Mythologically, Satan actually could take the form of a succubus to steal men's semen, after which he would turn into an incubus and pass it on to a woman, in order to have kids. How exactly this was supposed to transmit Satanic genes is undetermined.
In media that features this trope, it's not uncommon for Ol' Scratch's disguise to slip at times, revealing the hideousness beneath the attractive form.
- Ah! My Goddess: Generally, the demons are no less attractive than their goddess counterparts.
- Hild, while not Satan him/herself, is still the C.E.O. of the Infernal Realm.
- Hagall: in the manga, when Hild is removed in a coup by her deputies, and the position is taken by Hagall, who is not a bad looker either.
- The Devils of the Runaway Spirit Squad from The World God Only Knows are various degrees from cute (Elsea and Haqua) to hot (Nora).
- Half of Tsuki Pro's "Origins" illustration series, depicting the cast of Bishounen idols as angels and demons.
- My Balls: All of the demons are hot women, why would Satan be any different?
- The Devil Is a Part-Timer!: The main character Maou (Satan) appears as a bishounen in his de-powered human form, while his true form is a sexy beast.
- In Maoyuu Maou Yuusha, Maou-sama is the leader of the demons, the ultimate enemy of mankind and a gorgeous woman. Subverted in that she is closer to Prometheus than to Lucifer and wants a sustainable peace between their realms.
- High School DXD is filled to the brim with attractive demonic women, as well as demonic men. The main female protagonist Rias Gremory is one of many examples.
- Devils in Daily Life with Monster Girl come in three categories: while Lesser Devils look like prepubescent kids despite being fully grown, Greater and Elder Devils look like late teens and young adults respectively and fit this trope quite nicely. Case in point, the Greater Devil Lethe and Elder Devil Saki from the now-defunct web game of the series.
- Panty & Stocking with Garterbelt has the Demon Sisters, main villains of the show, who are Hot as Hell along with the two "angelic" protagonists, Panty and Stocking Anarchy.
- In Johnny the Homicidal Maniac, the devil has a few different scary, horned male forms, but assumes the form of a cute cheerleader girl because it's one of the things that Johnny likes the least.
- On more than a few occasions, Loki in the Marvel Universe takes on a female aspect, often just to mess with Thor.
- Lady Death from Chaos! Comics, Avatar Press, and Boundless Comics. After overthrowing Satan himself, she is, in fact, the ruler of Hell. Meanwhile, Purgatori from the same universe is actually a vampire, but, due to her Fallen Angel blood, she appears to look like a devil (wings, horns, red skin...no goat hooves, though).
- Marvel Comics tends to portray Hela, ruler of the Norse land of the dead, as a beautiful, seductive woman. In mythology, she's often portrayed as half-alive half-corpse. In some continuities, she still is half-corpse. Her costume is enchanted to give her the appearance of healthy beauty.
- Lady Blaze, the current queen of Hell in The DCU. With her helmet on, she has creepy glowing eyes and a Slasher Smile. Without it...
- X-Men: Azazel toyed with other people making them believe he was a devil, and he also seduced Mystique.
- In the 1990s version of the Vampirella comic, her sexy mother Lilith rules Hell. (Luckily for Vampi when she dies and ends up there; her mother gives her a mission to fight vampires on Earth.)
- Sexy devilettes are the shtick of comic artist Coop (Chris Cooper). You find them on countless music concert ads.
- Satan's Hollow has a female demon/succubus in Hell's court who serves as Satan's Queen. She looks like a cross between a Xenomorph and Daenerys Targaryen, which is about as sexually confusing as it sounds.
- In The Wicked + The Divine, Lucifer of the modern pantheon incarnates into the body of a young woman who dresses like the Thin White Duke and goes by Luci.
- In Death Isn't All It's Cracked Up to Be Satan, while female and reasonably attractive, was more mischievous than evil. Similarly, Hell was more about punishment and redemption than torture and temptation.
- in the Good Omens' fics of A.A. Pessimal, the hierarchy of Hell is fairly masculine. Although Hecate, beautiful Queen of Darkness and Insane Imaginings, is definitively female. Anthony Crowley also encounters Hell's training college for succubi - demons in female form sent out to tempt men with lust. He has a Friends with Benefits arrangement with a succubus called Lilith. Crowley himself, in accordance with one of the more gnomic scriptures of Genesis, is tasked with seducing a human woman and ensuring she has a half-demonic child - a Nephilim.note He isn't above sex but after six thousand years would prefer to curl up in bed with a good book or an entertaining box set on the DVD.
- The 2000 remake of Bedazzled, with Elizabeth Hurley as Satan. In the original version, Peter Cook wasn't too bad looking either.
- The Ninth Gate featured the devil, aka Irene Adler, described by the main character as the most beautiful woman he had ever seen.
- There was a movie called Hunk in 1987 that was sort of a parody of the Deal with the Devil plot. While the Devil was portrayed as a balding, overweight, middle-aged man, his servant - who actually presented the contract to the protagonist - was female and a knockout.
- The Devil's Advocate. The Devil briefly takes on the appearance of a handsome man with the same face as his own son, in fact. Given the Angelic Beauty trope, this is likely a reference to Lucifer as a Fallen Angel.
- The Goblin King in Labyrinth, explicitly designed as a Glam Rock-style Satanic Archetype, is highly sexualised (just look at those Painted-On Pants!) and portrayed by the handsome David Bowie.
- Lucifer (2016) And how! This trope served as the show's tagline during Season 1.
- The recurring Crossroads Demons may be in a different body every time, yet, somehow, they are always hot women. Invoked, since they're specifically using those hosts to make their deals more palatable to their male clients, which is Sealed with a Kiss. We also see some in attractive men, who interact with female clients. Crowley, the "King of the Crossroads", however, is shown occasionally coming to seal with the deal with male clients, just to amuse himself with how uncomfortable they are kissing men.
- Demon Queen Lilith wears this type of meat suit, even demanding that Sam have sex with her to seal a deal (Dean stops him). At least whenever she's not possessing a little girl to torment her family.
- Satan himself is played by Mark Pellegrino, and the muscular Jared Padalecki.
- In "The Song Remains the Same", Dean has a dream in which he's serviced by a stripper in a red devil's costume. Just to add to it, Anna, an actual angel who Dean had previously slept with, then shows up. She's visibly irked by his dream.
Dean: I take it all back. I love the Devil.
[Devil stripper is joined by a blonde in an angel's costume]
Dean: Now that's what I call peace on Earth.
- The Twilight Zone (1959) had Satan turn up in several episodes, usually as a conniving businessman. But one episode, "Of Late I Think of Cliffordville", featured the Devil as played by Julie Newmar. She doesn't really try to seduce the protagonist, and, within that episode, she might simply be the Devil's usual form, but looking like Catwoman while bargaining for a man's soul has gotta count as an advantage.
- The Comic Strip Presents: "Demonella". The Devil is Jennifer Saunders, c.1988.
- Star Trek: The Next Generation has Captain Picard facing off against the Ventaxian version of The Devil known as Ardra...and boy, she knows how to flaunt what she's got! It turns out, though, that this Ardra is not really a supernatural being, but a con artist using advanced technology to pose as one.
- The TV version of Good Omens (2019) has David Tennant, a reliable Mr. Fanservice for the nerdishly inclined, as Crowley (although he is not really very evil at all. He is quite stylish though). He is the only demon who fits this trope — the rest are quite grungy-looking.
- The video for Dimmu Borgir's song "The Sacrilegious Scorn" includes a painting of Baphomet morphing into a beautiful woman, though one with a deep male voice.
- Although technically Baphomet is a woman anyway. At least, she is when the caduceus sitting on her lap isn't being interpreted as something else entirely, in which case Baphomet is a hermaphrodite.
- "Hotter Than Hell", despite its title, is about the singer being infatuated with a woman who turns out to be married.
- Implied on "Radioactive" on the Gene Simmons 1978 solo album:
You're my food, you're my water;
You have to be the devil's daughter.
- The subject of Ringo Starr's "Devil Woman" from Ringo
You look like the devil with horns in your head,
The only way I'll get you is to get you in bed.
- The music video for "The Devil" by Shinedown features a model playing the titular Devil trying to seduce the lead singer to his doom.
- The demon girls from Helltaker could all qualify, but it's played the straightest with Lucifer, the CEO of Hell. Much like the other Cute Monster Girls, Lucifer is a Badass in a Nice Suit, designed to invoke the creator's Author Appeal of ladies in suits. Lucifer is something of a Tsundere, but she's presented as a very attractive and confident woman. In the game's ending, she's also shown to be the one who helps out the Helltaker the most in his day-to-day life.
- In Mystic Square, back in the PC-98 days, the Goddess of the effective equivalent of Hell is Shinki. Not only a Designated Antagonist, since she had nothing to do with the calamity in the game, but also a (possible) mother of returning heroine Alice (canon isn't quite clear on that point).
- Legacy of Lunatic Kingdom introduces Hecatia Lapislazuli, goddess of the three hells (Earth, Moon and Spirit World)...who's an attractive Perky Goth.
- Millenia from Grandia II. She very nearly manages to rape Ryudo...well, it would be rape, but it's hard to say.
- In Princess Maker 2, it's possible for the player character's daughter to become the Princess of Darkness. She literally defeats Lucifon and takes his place, and given her Head-Turning Beauty status, this trope is played straight.
- Shin Megami Tensei: Strange Journey:
- Louisa Ferre is what happens when Lucifer is portrayed as a mysteriously seductive blond woman. Also, for the ladies, Louis Cypher of the other SMT games looks like a dead ringer for David Bowie, which, given his real-life sex symbol status, makes him very desirable regardless of one's preferences.
- Lucifer takes on a female disguise again in Shin Megami Tensei IV: a schoolgirl named Hikaru. She fuses with Walter in the endings of the game, though it's only explicitly shown that she's Lucifer in the Chaos ending.
- Subverted by Jezebel in Saints Row: Gat Out of Hell. Jezebel is the daughter of Satan, and very attractive, but she is not particularly overtly sexy. She comes across more as a red-skinned, goat-horned Disney princess than a more conventional succubus-type.
- Narbonic, although justified in that the demon pulled the shape from Dave's fantasies. Further, it's later implied that the Devil herself is female.
- Satan from Casey and Andy is a definite example - even though she loves him too, she's still Satan, and she doesn't play favorites...much. On at least a couple of occasions, she's seen subjecting the (frequently-dead) C&A to the torments of hell, answering Andy's complaints with "Waddaya want from me? I'm evil!"
- In Jack, the devil appears to the reader in the form of the cartoonist, but to Jack, it seems he appears as a woman since Jack refers to the devil as "she."
- The pair of succubi captured by The Mistress in Oglaf. One of Ivan's daily tasks is to oil down their bodies so they don't get dried out by their literal hotness. The Mistress further enchants Ivan's ejaculate to come alive and tattle on him if he masturbates, so not to injure himself should they inspire excessive sexual fantasies on his part.
- Parodied in The Powerpuff Girls with Him, who while never explicitly stated to be the devil certainly walks the walk and talks the talk. He dresses hot as hell with a pink tulle dress and thigh-high lady's boots but with the way he looks and acts it lands somewhere between being fabulous and frigging unsettling rather than being sexy.
- Also occasionally parodied with the Red Guy in Cow and Chicken, who actually was explicitly the devil in the pilot (though this was quietly dropped in later episodes). Though nothing about this pudgy nude big-nosed devil who walked around on his butt cheeks could be considered conventionally sexy in any sense of the word, he certainly believed himself to be hot and acted as such. Especially when "Cleopantsless◊" shows up...
