Interspecies Adoption

Even in settings where talking, civilized, or funny animals exist, adoptions will still happen between parents and children. Some parents are caring enough to take in a child, regardless of their species. They may be animals raising a human child, humans raising an animal child, animals raising animals of a different species, or any combination of the three. It doesn't matter, as adoption is still adoption, and parents will always be parents. The subject of the adoption may or may not even be an issue among society.

This is a supertrope of Raised by Wolves and Raised by Humans, as well as cases that aren't covered by either trope. It may also overlap with Moses in the Bulrushes and (especially in comic settings) Oblivious Adoption. Contrast Random Species Offspring when the child isn't just adopted - it's biological.

As seen in the trope image there are numerous cases of this happening in real life among different animal species, even among animals that would normally eat one another. There are also many accounts, though few if any verified, of children while lost in the wilderness being protected or even raised by animals. Also given that humans are technically animals as well, raising pets also counts.

  • In Transformers Victory, Star Saber, the new leader of the Autobots, adopts a human boy named Jean, who lost his parents to a Decepticon attack.
  • Lyrical Nanoha has quite a bit of this with the sheer number of adoptions, although it can be hard to tell due to most of the cast being Human Aliens:
    • Vivio (Belka) was adopted by Nanoha (Earth) and Fate (Mid-Childa).
    • Fate was adopted by Lindy (Firstraum in the Movie continuity).
    • Erio (Unnamed homeworld) and Caro (Alzus) were both adopted by Fate (though Lindy's name is on the paperwork due to Fate's age).
  • Ash's Rowlet in the Pokémon Sun And Moon anime is adopted by a flock of Pikipek, with a Toucanon and a Trumbeak as its adopted parents.

    Comic Books

The youngest of the three is a Cathar boy (a feline-like race featured prominently in some other Expanded Universe works) whom they adopted after rescuing him from slavers. Awwww!.
  • Hellboy is a demon who was adopted by a human parent named Dr. Bruttenholm and raised under the watch of the Bureau of Paranormal Research and Defense. He was raised to appreciate humanity, even if he constantly has to deal with the fact that he's frighteningly different from them anyway.
  • Superman:
    • Superman is probably the most famous example of this trope. He's an alien sent to Earth as a baby, and he grew up on a farm by the Kent family.
    • And later, Lois Lane would fulfill this trope when she and Clark become the foster parents of Chris, another Kryptonian child.
  • Teenage Mutant Ninja Turtles: four adorable baby turtles fall into a sewer and are adopted by an ordinary rat (other than the whole "knows ninjutsu" thing). Only later do the five mutate and become intelligent.

    Fan Works 
  • In Diaries of a Madman, Navarone (a human) ends up adopting Taya (a unicorn) as his daughter.
  • This is recurrent in the Gensokyo 20XX series, with Reimu, Renko, and Maribel (formerly human) being adopted by Yukari (a reality warping yokai) and Chen (Nekomata) and Marisa (formerly human) being adopted by Ran and, later on, Ren (Kitsune). In that vein, we have Ran being adopted by Yukari.
    • This is actually used to an advantage in Foundling. Chen, disgruntled by Reimu at the festival, is given something of a dressing down by Yukari, reminding her that she is adopted and that, no matter what species, someone loved her, regardless if anyone wanted her. Said dressing down made her shut up.
  • It's not the Raptor DNA: Rexy the Tyrannosaurus Rex has adopted Elise (an Indominus Rex) and Tim (a human, and the same one she terrorized during the events of the first film) as her children.
  • The Rise of Darth Vulcan: During the raid on Cirrus and Hilltop, one of Vulcan's Diamond Dog mooks decides to adopt an Earth pony foal as her own. Vulcan isn't happy about this, but caves when both dog and foal give him Puppy-Dog Eyes, caving to their combined cuteness.
  • The Equestrian Wind Mage: A key point of the story is Vaati (a Hylian/Minish/Demon thing) adopting Scootaloo (a pony). Both are incredibly happy with this setup.
  • The many, many fics about Fluttershy adopting a non-pony child, usually a baby Changeling or orphaned human.
  • Many other My Little Pony: Friendship Is Magic fanfics, including The Nuptialverse, have Twilight (a unicorn) adopting Spike (a dragon), whom she had hatched when she was younger.
  • Seven Days In Sunny June: Discussed in 7SDJ: A Mother's Duty by Celestia and Twilight Velvet, and explicitly identified as being against the law in Equestria, barring "mitigating and emergent circumstances", which "shall only be considered on a need by need basis". Celestia herself admits that she didn't write the law and should have checked more closely before it was made official; the only reason she hasn't changed it since is because it would be seen as a "gross abuse of the law" and a conflict of interest, since it would have cleared the way for her to adopt Sunset Shimmer, or Twilight Velvet and Night Light (as the parents of her personal student) to adopt Spike.
  • In First Meetings Universe — a Mass Effect-MLP:FiM crossover — Mass Effect: Shepard and the Rainbows starts with a pegasus soldier saving a human girl from pirates and then adopting her. Thus Riley Shepard, Rainbow Dash and Scootaloo end up being sisters.
  • In the Transformers Prime fanfic, Suddenly, Shattered Glass versions of Arachnid and Breakdown adopt a preschool June when she becomes the Sole Survivor of an Autobot attack in Jasper, Nevada.
  • Actually subverted in A Hollow In Equestria where Princess Luna proposes invoking this trope for Ulquiorra Cifer's benefit. It's eventually revealed that he turns down the offer, explaining that it would create more problems than it would be worth.
  • Happens at least twice in The Bridge and its expanded universe. The first was Azusa Aoki adopting and raising Junior. In the expanded "Amalgam-Verse", Tori Wylder, a Glaistig, winds up adopting a Puca named Haley Comet, a Jorogumo named Kumiko Murakumo, and her lone human son, Theodore Wylder.
  • In the Zootopia fanfic Judy's New Life foxes and bunnies can't interbreed so Nick and Judy adopt a pair of skunk kits.

    Films — Animation 
  • Kung Fu Panda:
    • Po is a giant panda raised by a goose; this goes unmentioned in the first movie, but becomes a major plot point in the sequel. His biological family was seemingly massacred by Lord Shen during his attempt at wiping out the Pandas, but Po's father is still alive and living in a hidden panda enclave
    • Master Shifu, a red panda, also adopted Tai Lung the snow leopard and Tigress the tigress. The rest of the Furious Five might qualify as well.

    Films — Live-Action

  • The Stuart Little movie did this to remove the Fridge Logic from the original book (where the titular mouse character just had human parents for no apparent reason). This verges on Ascended Fanon, as E.B. White received letters from adoptive children for years talking about how Stuart was a wonderful allegory for the way they felt... despite White having no such intentions, and Stuart explicitly being Mr. and Mrs. Little's biological son in the book.
  • Disney's The Ugly Dachshund. A Great Dane thinks he's a dachshund because he was raised by a dachshund mother.

  • Elf: Buddy is a human adopted by Santa Claus, and raised among elves.
  • In Babe, Babe the pig is adopted by Fly who is a dog.

  • In the Discworld novel Guards! Guards!, Carrot is a human adopted by dwarves. He is completely oblivious to this, even when his adoptive father tries to explain that there's a reason he was always too tall to fit in dwarf passages correctly. Notable in that even after it's been explained to him and he's accepted that he is biologically a human, Carrot still considers himself a dwarf, albeit a very tall one. Though, in Discworld being 'a dwarf' is as much a matter of cultural identity than it is a fact of one's species.
  • "The Ugly Duckling" is a classic example of this trope. A swan raised by a duck.
  • RuneScape: Betrayal at Falador, Kara was adopted and raised by dwarfs.
  • The children's book Tyranosaurus Drip by Julia Donaldson is about a duckbill dinosaur "adopted" by tyrannosaurs. (Mother Tyranosaur can't count, and doesn't realise there's one more egg than there should be.)

  • In Team Human, Kit is a teenager raised by a family of vampires; he's spent very little time around non-vampire humans.

    • The X-wing series gives us Viull "Skut" Gorsat, a Yuuzhan Vong abandoned by his biological parents and adopted by a human family. His human dad is the reason he joins Wraith Squadron, because as a child he was told stories of how they rescued his father.
    • There is also Tahiri Veila, who was adopted by the Sand People.
    • And let's not forget Han Solo himself also falls into this category. He had been orphaned at a very young age, and while working for a rather nasty thief, he gets taken in and cared for by a kindly, elderly female Wookie. Han even comments in a later novel that due to the love she gave him, and the fact that Chewie and other Wookies have saved his skin on countless occasions, he feels he owes the Wookie's a life debt, not the other way around.
  • This comes up in The Demon's Lexicon when Nick is revealed to be a demon, raised mostly by his brother Alan.
  • In Spectrum by Sergey Lukyanenko the human heronote  ends up adopting a teenage alien bird-girl as a "reward" for saving her life. His Love Interest cracks jokes about an "interplanetary paedophile", but demonstrates that she can be a capable mother, despite being in her late teens herself. The adopted girl turns out to be the Chosen One prophecised to wake her planet from its millennia-long Diesel Punk stasis where rigid laws allow the population not to think. She ends up becoming the queen equivalent and legally adult and staying home.
  • In the 1920s Winnie-the-Pooh books, Tigger (a Tiger toy) lives with Kanga and Roo (Kangaroo toys) and is considered part of the family.
  • In the Warrior Cats novella Hollyleaf's Story, Hollyleaf attempts this for a day or so with a fox cub lost in the tunnel, finding it and caring for it before later bringing it back outside.

  • In Brimstone Angels, heroine Farideh and her twin sister Havilar are tieflingsnote  who were adopted and raised by a dragonborn named Mehen.
  • Horton Hatches The Egg twists this trope due to the story's Anvilicious theme of nurture overcoming nature. Since Horton took responsibility for the egg that Mayzie abandoned, the chick finally hatches as an elephant-bird hybrid, and identifies Horton as its parent, rejecting Mayzie.
  • James and the Giant Peach: Less so in the original novel, but in the movie and the musical adaptations, we have the human child James, an orphan, who is adopted by his humanized insect companions. They turn out to be very loving, adoring parent-figures to James, unlike his abusive guardian aunts who he was living with after his mother and father died.

  • Darwin from The Amazing World of Gumball used to just be the Watterson family's pet fish, but he developed intelligence, grew legs, became Gumball's best friend, and the family adopted him as one of their own. The parallel to real life interracial adoption is made especially obvious by how both of Darwin's voice actors are black, but the ones for the rest of the family are white.
  • In My Little Pony: Friendship Is Magic, Twilight Sparkle (a unicorn) had to induce a dragon egg to hatch as part of her entrance exam in magic school. She ends up being a Cool Big Sis/Parental Substitute to him, who serves as her underling and assistant. Word of God says that it was actually Princess Celestia who raised Spike after he hatched, while Twilight continued her studies. Still fits the trope.

The lioness, overcome with grief, decided to separate another oryx from its herd and adopt that one. It promptly died too.
