Beast and Beauty in Western Animation.
- Adventures of the Galaxy Rangers: In "Edge of Darkness", Goose is dragged through a black hole that bugs his powers, morphing him into different creatures. He crashes on Ozark and a beautiful cowgirl called Annie tries to shield him from the other locals, who have no tolerance against off-worlders. Of course that Goose's transformations into a half-irrational, growling beast don't help. His ranger comrades save him in the exact moment he is about to be shot by the local xeriff, although he has just saved a local child from drowning. Annie helps Goose to calm down, so Doc may restore him back to his human form; the latter even lampshades the two, by calling them "Beauty and the Goose". Unfortunately, Goose is unable to return Annie's feelings because he still loves Darkstar.
- Aladdin: The Series: Apparently, the writers of the TV series were very fond of this trope:
- “Garden of Evil” parodies/twists the fairy tale. When the Sultan was young, he picked up a flower of a magnificent garden, prompting the wrath of its master, a plant-man called Arbutus. The creature demanded the future Sultan to promise him his most valuable treasure… which, twenty years later, turns out to be Jasmine. Subverted when Arbutus' treats Jasmine not as his future bride, but as an ornament for his garden. When she says she is not an object, he rants that’s exactly how humans treat the flowers and plants in general. Jasmine realizes that he loves his garden as much as her father and Aladdin love her, but is unable to stop the latter from accidentaly killing Arbutus, by cutting off the flower that is his heart. Jasmine plants the flower somewhere outside and it breathes, hinting that Arbutus will regrow eventually.
- Gender-flipped in “ Eye of the Beholder“, when Mirage tricks Jasmine into using a lotion that slowly transforms her into a snake woman.
- Played straight and gender-flipped in "Seems Like Old Crimes", when the con artists Aziz, Minos and his lover Fatima become monsters(respectively, a goblin, a minotaur and a harpy) as a punishment for trying to steal the sacred Destiny Stone.They use their newfound powers to loot Agrabah, but Fatima wants to take revenge on Aladin, to whom she blames for having become a monster because he tried to stop them from stealing the gem. However, after Jasmine saves Aladdin's life, Fatima realizes that both are like her and Minos and takes a Heel–Face Turn. Aziz tries to kill her, but Minos pushes Fatima of the way and is burned, instead. The scene of Minos dying as Fatima touches his face is a frame-by-frame replay of Beast's death; luckily, the Destiny Stone turns them back into humans, giving them a second chance. Both decide to atone.
- The Amazing World of Gumball: "The Shell" has a gender-flipped version where Gumball is the beauty to Penny's beast. The episode even alludes to Beauty and the Beast multiple times.
- Batman: The Animated Series: In Mudslide, Dr. Stella Bates is a pretty scientist in love with Clayface/Matt Hagen, a former actor transformed into a clay blob that can shapeshift temporarily. Deconstructed because Stella is in love with the handsome man Clayface was once and he is manipulating her to find him a cure. And he won't listen to Stella's pleas to not kill Batman, subverting the Morality Pet thing.
- Lydia Deetz and Beetlejuice. One episode was called "Beauty and the Beetle," only the beast in this case was Neitherworld ape Thing Thong. Lydia helps Thing Thong gain some self-esteem.
- Ben 10: In "Benwolf", Ben and Kai seem this when he starts transforming into a wherewolf (actually a wolf-like alien), though she is more annoyed by his antics than anything. Subverted after he turns back to normal and Kai confesses that she was only interested on Ben because she thought she could train him.
- In Ben 10: Alien Force and Ben 10: Ultimate Alien, Gwen and Kevin fit both sides of the trope in several episodes.
- In “Kevin’s Big Score”, he is encased by Vulcanus into a taedenite shell that is a grotesque replic of himself. Gwen frees him, and Kevin gratefully embraces her.
- He suffers a mutation again at the beginning of Season 3, becoming an amalgam of the matters he absorbs most; even Gwen’s support is not enough to break him out of depression. He becames human again in the last episode and the two share a Big Damn Kiss.
- By her turn, Gwen becomes the Beast in “War of the Worlds” when she goes full Anodyte for the first time to defend Kevin from a Highbreed. He convinces her to snap out of this, or she might never be able to be human again.
- In the end of Aggregor's arc, Kevin is forced to absorb the Ultimatrix to stop the villain, but that turns him into a psychotic, hungry-for-power amalgam of Ben's aliens. Gwen spends the next episodes trying to convince Ben and the rest of their friends to not kill Kevin, and eventually finds a way to save him, although she almost dies in the proccess.
- Centaurworld: The Elktaur's backstory revealed in episode "The Last Lullaby" is one big Deconstruction of the "Beauty and the Beast" storyline. He was a half-animal creature who had self-loathing for what he was, she (the Princess) was a beautiful woman. He fell in love with her and (unknown to him at the time) the feeling was mutual. But his self-loathing got in the way of accepting that love, to the point where he banished his animal half (the Elk) just to have a happy ending as the changed human suitor (the General). The problem is, the Elk still loved the Princess, and the General locked him up so as not to risk losing his "Happily Ever After". This set off the domino effect of the Elk becoming a manifestation of the Elktaur's self-hatred, leading to the war that ruined the lives of both Centaurworld and humankind. Not to mention how the Beauty-stand in turns cynical at learning her husband lied to her and essentially abused his animal half.
- Dungeons & Dragons (1983): In "The Garden of Zinn", an ugly but gentle goblin called Solarz shelters the gang after Bobby is poisoned. Actually, he is Sir Lawrence, a king cursed by his evil sister, Zinn. He ends up saving the heroes from her ghostly minions and Sheila gratefully embraces him, crying a tear of gratitude that breaks the spell. Sir Lawrence gets to ask her to become his queen, but she refuses politely because she wants to go back home(also, she only sees him as a friend). Subverted and Played for Laughs when the broken curse turns Zinn in a goblin while she is marrying Erik in an attempt to avoid that fate.
- Futurama has a gender-flipped version with the strong, often violent one-eyed sewer mutant Leela and the amiable human nice guy Fry. She definitely typifies the "beat up anyone who might hurt him" side of Beast, he the emotional, kind, sees the good in the world side of Beauty.
- Gargoyles: Goliath and Elisa Maza — he's a gargoyle, she's a human, but they fall in love anyway. During a Halloween episode, Elisa even dresses as Belle from Disney's Beauty and the Beast. However, while they were good friends, they didn't really notice that other options might present themselves until Elisa was magically changed, briefly, into a gargoyle (and then, later, Goliath and the others became humans, also for a short time). Interestingly, it was Goliath (the "beast") who didn't find Elisa physically attractive at first, not the other way around. Elisa had always been attracted to him.Goliath: I never realized, when you were human, how beautiful you are.
Elisa: *wryly* You mean you thought I was ugly?
Goliath: Well, uhh... Careful! Updraft!
- Green Lantern: The Animated Series: Razer and Aya have nuances of this trope. Razer begins as the Beast: he is a reformed red lantern who enlisted to avenge the death of his wife until discovering he was manipulated, and all of this made him bitter, violent and depressive. Aya is the Benevolent A.I. of Hal Jordan's ship who built a robotic body for herself. She is calm, curious, acts as Razer's Morality Pet and tries to understand his pain. In the season 2, the tables are reversed. Razer came to abhor violence, while Aya has had enough of people treating her as machine, instead of a person., which takes her to a Face–Heel Turn and decided to eliinate all the organic life in the universe, along with with suffering. It’s Razer who plays Beauty then, trying to reasonate with her. He eventually succeeds, at a great cost.
- He-Man and the Masters of the Universe (1983) has one episode specifically called “Beauty and the Beast”, although it’s not romantic. A storyteller tells “Beauty and the Beast” to a group of children as Teela comments that she loved the fairy tale when she was little. Shortly after, Skeletor kidnaps Orko and Teela and hides them in the palace of a king that Evil-Lyn turned into a "monster"(a bald, gray-skinned man with bat wings instead of ears). The king reluctantly complies because otherwise his subjects will become as hideous as he is. Of course Teela convinces him to stand ground against Skeletor; although he is easily defeated by the villain's gang, she thanks him with a kiss that breaks the spell.
- In “The Shadow of Skeletor”, Teela helps Man-E-Faces to rehearse a theatral release of Beauty and the Beast.
- In “The Return of Granamyr”, He-Man and Man-At-Arms must help a dragon that wants to become human because he fell in love with the daughter of a wizard. She loves him back, but her father demands that her suitors go through a series of tests that only humans can perform; since her dragonfriend is not allowed to be turned into a human until she is commited to him, it's up to He-Man to do the hard work.
- Jane and the Dragon: Has this trope with the titular characters - a peasant girl who lives and works in the royal palace who is best friends with the resident dragon. While their relationship is entirely platonic it should be remembered that Dragon does not do well when Jane isn’t around and she is the only one who can calm him down.
- Maya and the Three:
- Played straight with Camazotz and Zynaya. As the God of Bats, Camazotz has a very beastly appearance, with purple skin and teeth so big that he shouldn't be able to talk, but that didn't keep him of being loved with the human warrior. They had a son, Zatz, but she was eventually murdered and Camazotz forced to return to Lorde Mictlan's reign. Zynaya's soul became a star; both Camazotz and Zatz find comfort seeing her at night. Camazotz ends up killed by Lord Mictlan, and becomes a star,too, joining her.
- Gender-flipped with Michi and Rico. Michi was raised by animals after her people cast her away because of her albinism, but the responsible for her violent behavior are the humans who killed her adoptive family. Despite having also a Dark and Troubled Past, Rico has a humorous, friendly personality and, in spite of Michi's initial rejection (and a temporary crush on Picchu), she ends up returning his feelings.
- Subverted with Lord Mictlan and Lady Micte. She married him only for status and power; still, she is not repulsed by his hideous appearance (he's got two heads that become one, and menacing fangs), but by the monster he is within.
- Monster High: Iris Clops and Manny Taur. The former is a demure, clumsy, soft-spoken and friendly ghoul who's the same height as Draculaura. The latter is a hulking temperamental Jerk Jock with a heart of gold.
- My Little Pony: Friendship Is Magic: Zig-Zagging Trope, and employed platonically, in "Keep Calm and Flutter On", where the sweet-hearted pegasus Fluttershy befriends the beastly (in more ways than one) Discord. First it's subverted because Fluttershy is charged by Princess Celestia to reform Discord, while Discord only plays along because he'll get turned to stone if he doesn't, and craftily plots to exploit her kindness and secure his freedom. It's then double-subverted when Fluttershy shows him so much kindness that he actually starts to Become the Mask. Then comes a triple-subversion where Fluttershy ends their friendship after Discord goes through with his plan anyway. This directly leads to a quadruple-subversion where Discord, realizing he cares about Fluttershy after all, pulls a genuine Heel–Face Turn to win her back.
- She-Ra and the Princesses of Power: Hordak a stern, bat-looking Dark Lord on Life Support and Entrapta, a cute human princess who is also a Gadgeteer Genius. Slightly subverted, for it’s hinted that Entrapta finds Hordak attractive, but he doesn't notice how beautiful she is until she comforts him about his self-esteem issues. Besides, Entrapta is not exactly a Morality Pet for Hordak, but encourages him to be himself instead of Horde Prime’s shadow. For good measure, many moments between Hordak and Entrapta recreate shots of Disney's film
.- Adora and Catra's relationship fits the trope, too, since Catra is a Cat Girl with a very unstable temper who fights for the Horde and Adora is the kind, righteous saviour of the world. However, it takes all the five seasons for them to realize their true feelings towards each other.
- Sherlock Holmes in the 22nd Century: Two episodes are based on the trope: "The Crooked Man" and "The Creeping Man," both concerning men made beastly through genetic manipulation by a rival suitor.
- Star vs. the Forces of Evil: Eclipsa and Globgor. She is the sweet, graceful daughter of the genocide queen Solaria the Monster Carver, while he is a gigantic, four-eyed, red-skinned, horned monster that used to eat Mewmans until Eclipsa convinced him to become a vegetarian. Not that would make any difference to the Magic High Commission or the rest of Mewni.
- Wild C.A.T.s (WildStorm): The Huge Guy, Tiny Girl duo — they're just friends but the Tiny Girl ensures that the Huge Guy remains a sane Gentle Giant.
- In X-Men: Evolution, the demon-esque Nightcrawler becomes the boyfriend of pretty-girl Amanda Sefton. And in Wolverine and the X-Men (2009), he has some mutual UST with the smokin' hot Scarlet Witch.
