Humanity Ensues / Western Animation

• In Adventure Time, this happens to the Lich, as Finn splashes him with healing water that turned into a giant human baby (albeit still with the horn). Although the Lich was originally a human transformed by the Mushroom Bomb, so...
• In The Amazing Feats of Young Hercules, this happens to Falina the sable at the end of the movie. However, she was already a human princess before she was cursed into a sable.
• The Amazing World of Gumball:
  • The episode "The Nuisance" sees the Wattersons grotesquely turned into a stereotypical nuclear family of humans after they become model citizens (except Darwin, who becomes a dog).
  • In the episode "The Lady", Richard has a female alter-ego named Samantha, achieved via Full-Body Disguise, which also makes him look entirely human.
  • The series finale "The Inquisition" has the superintendent of Elmore Junior High trying to turn all the students into humans (first cartoon humans, then live-action ones like him). It turns out to have been a plan by Rob to let them escape to "the other place" before Elmore is sucked into the Void.
• The Angry Beavers episode "I'm Not An Animal, I'm Scientist #1" ends with Norb, Daggett and the other forest animals being turned into human beings.
• The Attack of the Killer Tomatoes! animated series had Tara Boumdeay, a female tomato who could be turned into a teenage female human by sneezing. Sneezing also turned her back into a tomato. It Makes Just as Much Sense in Context.
• Gorilla Grodd's first appearance in Batman: The Brave and the Bold ends with him being turned into a human after his Devolution Device is put in reverse, though he's a gorilla again in later episodes.
• Ben 10: Alien Force has Albedo, a Galvan (species of super-smart small aliens), being a victim of this: after he attempted to create his own Omnitrix and set it to match human protagonist Ben's one. The problem is, an Omnitrix has its owner's DNA as the default form, meaning he ends up turned into a clone of Ben. He was displeased to say the least. Amusingly, from some perspective, this a rare case where being turned into a human shouldn't be that bad technically talking: after all, humans are taller and physically stronger than Galvans, and it has been shown several times that Albedo retained his Galvan intelligence. The problem is, Albedo has a huge ego and believes Humans Are Flawed, so he considers it as unbearable.
  Albedo: I am stuck in a stinky, sweaty, noisy, hungry, hairy, smelly teenage human body, constantly craving chili fries and scratching myself in places I suspect are inappropriate!
• Happens to the titular character of Bunsen Is a Beast in the episode "Handsome Beast" after he eats a can of fancy body spray.
• Happens to a wolf named Harry in the Chip 'n Dale: Rescue Rangers episode "A Wolf in Cheap Clothing". He's the victim of Professor Nimnul's latest plan which involves swapping species so he can turn into a Wolf Man. (After said experiment goes awry, the episode also includes some spectacularly insane Mix-and-Match Critters.)
• In the Conan the Adventurer episode "Bones of Damballa" Skulkar, an undead skeleton warrior servant of Wrath-Amon is transformed back into his original human form, and tricks Conan and Zula into helping him get his "other" form back.
• The Fish Hooks episode "Pool Party Panic" involves Milo waking up to find that he and everyone else is human; however, it turns out to be All Just a Dream.
• In the Futurama episode "Anthology of Interest II", Bender is turned into a human and discovers the joys of food and dancing. He proceeds to spend a whole week eating, drinking, and partying. By the time the other characters find him, he's an outrageously fat slob in terrible shape. He proceeds to teach scientists how to live it up, and ultimately dies due to his lifestyle.
  Leela: Bender, you drank and smoked when you were a robot.
  Bender: Yeah, but now it's bad for me!
• Gargoyles:
  • In "The Mirror," as a result of Puck "misinterpreting" Demona's demands, Goliath and his clan are all transformed into humans (Bronx becomes a dog), while every human in the city is transformed into a gargoyle. As an added twist, the transformed don't notice the change, being convinced that they were always in their current form and that it's the un-transformed party who suddenly changed species. Aside from that they retain all their memories, which allows the gargoyles to realize something's wrong when they note that their memories of gliding are contradicted by their current lack of wings.
  • Demona gains the ability to turn human by day after the above run-in with Puck. Despite initially being repulsed by this development, due to her genocidal hatred of humans, she successfully uses her new form to become a Corrupt Corporate Executive, which leaves her far better equipped to implement her murderous schemes (and even got married to the guy who wants her dead because he didn't recognize her human form).
  • Puck himself counts, in a way; he created his human identity (Owen Burnett) and voluntarily lived in it for years (very well, too), but when he helps Xanatos and the gargoyles fight Oberon, his punishment is being trapped in that form permanently, except when he needs to train or protect Alexander. Since he's Puck, he proves entirely capable of engineering loopholes for himself on occasion.
• In Green Lantern: The Animated Series, Aya constructs herself a humanoid body, if only so that she can be a "real" Green Lantern, at the end of "Into the Abyss".
• In The Grim Adventures of Billy & Mandy episode "Night of the Living Grim", Grim contracts a magical disease called "Encroaching Doom Syndrome" that ends up turning him into a mortal human. Hilarity Ensues until the end of the episode where a slime monster that appeared earlier eats him, but he comes out of the monster back in his skeleton form.
• In the Halloween Episode of The Life and Times of Juniper Lee, it's revealed that monster children spend Halloween magically disguised as humans. One kid, however, makes a deal to make the spell a bit more permanent for everyone affected, requiring June to go through a Chain of Deals to reverse it before midnight.
• Happens to Ohno of the Mighty Orbots in the episode "Wish World". She's forced to return to being a robot when it turns out the Orbots cannot combine without her.
• In Oscar's Orchestra episode "The Soothsayer's Convention", Oscar the piano is turned into a human, although given the various... quirks of his human form (for starters, he's still blue head to toe) it would be fairer to say Ambiguous Humanity Ensues.
• She-Ra: Princess of Power: In "Enemy with My Face", the Melog is a creature of mud and rock that can take on the traits of whoever it touches. She touched She-Ra, gaining her strength, but also her personality, eventually leading to a Heel–Face Turn. She-Ra was able to use the magic of her sword to turn the Melog into a human girl.
• In the Super Little Fanta Heroes retelling of The Hunchback of Notre Dame, Djali is turned into a human girl so that Pierre Gringoire can marry her. Yes, really.
• The Movie of Teacher's Pet revolves around this trope - Spot, who has always wanted to be human, becomes a human man thanks to a Mad Scientist. In the end, he decides he's happy being a dog, and is returned to normal.
• The Teenage Mutant Ninja Turtles (1987) episode "The Gang's All Here" had Michaelangelo become a human after eating some mutagenic cookies.
• Transformers:
  • The Transformers:
    • The episode "Only Human" involves Springer, Rodimus Prime, Ultra Magnus, and Arcee having their minds put into synthoid human forms by the villainous Victor Drath (with the help of the suspiciously familiar Old Snake). While they were "created" with white t-shirts and boxers, by strong coincidence they managed to find clothing that corresponded to their paint scheme hanging on four hooks inside an empty warehouse.
    • An awkward section of this episode featured Rodimus being invited into Michelle's house followed by a fade to black. The next Rodimus-based scene is set the next morning, when Michelle betrays him to her boyfriend Drath. It's not completely clear what went on that night, but Rodimus seemed very uncomfortable with it.
    • The earlier episode "Sea Change" involves Seaspray falling in love with a Human Alien woman, resulting in his entering a magical pool in order to become a "human" man (however, he keeps his metal feet and his 'bubbly' voice"). The alien woman later uses the pool to become a robot.
  • Transformers: Animated appears to pay tribute to "Only Human" with the two-parter "Human Error", which starts with the Autobots partying it up on Christmas Eve and going to sleep/"stasis", and then Optimus Prime waking up and finding himself—and all the other Autobots—in human form. This turns out to be a Decepticon plot to demoralize them into changing sides. It doesn't work. They get to indulge their curiousity about food, Optimus appreciates humanity better after trying to manually drive the fire truck, and Prowl figures out the VR world and uses it to gain Matrix-like power to help them return to their robot forms.
  • A temporary and non-supernatural variant occurs in Transformers: Rescue Bots - Graham designs a human form for Blades using a portable hologram emitter so that the latter can get promoted in Lab Pioneers.
• Blinky from Trollhunters experiences this for a short while after being exposed to a number of unknown chemicals in Gatto's stomach.
• The second Halloween Episode of We Bare Bears includes a segment where Charlie the Bigfoot turns himself into a human via a magic arcade machine in order to be able to go into the city with the bears without worrying about being seen by humans. However, the bears no longer recognize their pal Charlie this way, so Charlie goes back to the machine to turn back to normal, only for havoc to ensue when the magic arcade machine doesn't work the way that he wants it to and creates increasingly strange realities where Charlie is still a human and the world around him is messed up in odd ways. He does end up turning back to normal in the end, except that he and the bears now have pouches containing younger versions of themselves on their bodies. Charlie shrugs and carries on.
