Hybrid AU

Hybrid AU (also known as Animal AU and Animalized AU) is an AU in the fandom where the Big Four are hybrids, portrayed as animals and have animal like abilities or parts.

About the AU
Spawning from fanart, this AU places the Big Four, and other such characters as Hybrids and have human characters animalized (or portrayed as animals, its a bit like genderbending), while animal and "creature" characters are humanized (portrayed as humans) for pairings, crossovers and other AUs. The four also have animal-like parts (like ears and tails) on their bodies or have their abilities. The four can also be partnered up with (random) animals, that aren't from any film, TV shows, books or games.

Hiccup Horrendous Haddock III
Fans have infused Hiccup with Toothless as they turned him into a Night Fury-human Hybrid. They have also made him as a human with dragon like abilities (because of his dragon like soul), like understanding what they are saying, breath fire and having dragon like eyes; or just have him turned into a Night Fury.

In some modern crossovers and AUs he is Toothless' owner, when his dragon is cast as a house pet (like a black cat or three legged dog) or as a horse that he rides from time to time.

Jack Frost
The animals that Jack has been turn into by fans is a Polar Bear for the Jarida pairing (when Merida repeats her story with him, as she gives him the spell that turned her mother into a bear) and as a White Ferret for Hijack. He is also portrayed as a Wolf (by placing the ears and tail on his human body) for the Red Riding Hood AU and Werewolf AU, and as a Cat (for his role as the Cheshire Cat for Wonderland AU and Chat Noir in Miraculous Ladybug AU), while his Patronus in the Hogwarts AU commonly takes the form of a Fox or Hummingbird. Jack is also seen partnered up or being good friends with Arctic and Winter animals or with a wolf.

Jack can even be featured as his human self, for other AUs, crossovers and even pairings. Much like the rest of the Guardians of Childhood when fans portray them as humans.

Merida DunBroch
Fans have given Merida the form of a cat or raccoon for Jarida. She can also be portrayed as a bear, because of the spell that she used on her mother, for her "beast" form in Beauty and the Beast AU and the form of her Patronus in Hogwarts AU.

Rapunzel Corona
Rapunzel can be portrayed as either a horse (because of her relationship with Maximus) or infuse her with a horse, to make her a centaur (seen in Centaur AU) or portrayed as a chameleon (due to her relationship with Pascal) or have chameleon like abilities. Fans have also placed as a cat.

Dragon Riders
The Dragon Riders are dragon Hybrids as fans infused them with their dragons. While their dragons are portrayed as Humans or other kinds of Animals, like cats, dogs, birds or any other kind of reptile.

Toothless
Toothless is portrayed as a Human or a Night Fury-human Hybrid for the Toothcup, Stormless, Toothjumper and Buckteeth pairings. A Cat or Dog for the Modern AU and crossovers, and as a Horse for the Ranch AU. The Night Fury could even be placed as a Bat, due to the likeness of his wings and has been shown to sleep upside down. While in The Little Mermaid AU, Toothless is featured as a Shark, Dolphin or a Orca that is close with merman Hiccup.

Stormfly
Stormfly is portrayed as Astrid's pet Bird or Dog for modern crossovers and as a Human. She is also seen as a Deadly Nadder-human Hybrid for the Ermfly and Stormless pairings.

Guardians of Childhood
E. Aster Bunnymund, Toothiana and Sanderson Mansnoozie are portrayed as humans (humanized) or (normal) animals for Pairings, other AUs and crossovers. Since Nicholas St. North already looks human and had been one before he became a Guardian, he'll most likely be given an animal form or have fans turn back time to make him a young human again (like with Jack); while the other three Guardians are turned into everyday people or human-animal hybrids.

Human Bunny is sometimes featured with still having his long, rabbit ears for when he is seen as a human-rabbit hybrid. He is sometimes given human ears, along with commonly having long or short, gray-blue hair that is the same shade of his fur, when he is giving long hair it is tied back into a ponytail. His human skin is mostly Australian tanned due to his accent and the location that Easter Island is said to be in, while the markings on his body are dark-blue tattoos. Bunny is also seen as a ordinary gray furred rabbit, much like the form he took when less children began to stop believing in him.

Human Tooth is mostly seen with long or short brown hair, that is sometimes given mutable colored-screaks on her fringe that match the colors on her wings, or the feather-"hair" on her head; her human hair is even placed as green on some rare occasions to match with the feathers surrounding her body. She is sometimes given feathered styled jewelry like earrings or hair accessories to wear, to serve as a reference of her human-hummingbird self. Her eyes commonly remain pink and her skin is sometimes tanned to the shade of where she originally come from in the world, due to her origin story from the Guardians of Childhood books. Her human self could even be made to look like her human form from the book series, as Tooth was once a human like her father until all of her baby teeth fell out and became like her mother. Tooth can also be featured as a green feathered hummingbird; along with her fairies as fans also portray them as ordinary birds. As well as a hybrid of her human and feathered-fairy guardian self merged together, to make her a bird or fairy/guardian-human hybrid; with less feathers (while keeping a pair of green-feathered wings in place of her colorful fairy wings) and more human-like features.

While Sandy already looks human, his "pure" human self isn't that different from his original form. The only difference is that his body isn't make out of sand or all yellow around his body, except for his hair. The Guardian of Dreams can even be featured as the type of animals that his Dreamsand takes the form of.

Baby Tooth
The small, feathered tooth fairy is mostly featured as an ordinary green hummingbird (due to her bird-like appearance) or a young human child, while her queen's human form places her as an adult or teenager. Like Toothiana, Baby Tooth's human eyes remain the same and is commonly given brown hair, but with a yellow screak on her fringe. While other fans think that her hair should be green. Baby Tooth's human form as even been made to resemble Jack's little sister, as many believe that there is a connection between the two.

Tadashi Hamada
Tadashi is sometimes portrayed as a Fox or is given fox ears and tail, because of the "Kitsune" identity he takes most commonly in Dark AU and even Seasons Guardians AU. Fans have also turned him into Dog that takes care of his little brother or given him dog or cat ears and tail, when Hiro is portrayed as a puppy or kitten or has their ears and tail.

Hiro Hamada
Hiro is commonly seen as a cat or a Neko. Which is the Japanese word for cat and is commonly referred to as a half human half cat; a human with cat features like a tail and ears. Hiro is also featured as Kitsune, when he is given fox ears and tail; along with his brother as he is commonly featured as a fire wielding Kitsune by fans.

Baymax
Baymax is sometimes portrayed or seen as a human or a white cat (normal or robotic) because of his bond with Mochi. The white robot is also seen as a white (normal or robotic) coated dog, with a touch of black on his face between his eyes, to match with his robotic face.

Felonius Gru
Because of the bedtime story that Gru wrote for the girls, he is portrayed as a Unicorn in the book, while Margo, Edith and Agnes are the Kittens. Fans have also turn him into a Dog, with Lucy.

Maui
Since Maui is a shape shifter that can take on the form of many kinds of animals, with the help of his Magical Fish Hook, he can easily be portrayed as either one of his animal forms. Mostly as the animals that he transforms into the most; Hawk, Iguana, Beetle, Shark and Whale. He can even be a human-animal hybrid of them, as the top part of Maui's body had turned into a shark's head while the bottom part remained human; and vice versa when his hook was acting up.

Nightmares
While the Nightmares only have one animal form in the Rise of the Guardians film, they have a few other forms in its video game version. Those forms were of monkeys, rats, wolves, giant lobsters and even of elves and yetis. Fans have also given them other forms to take, mostly of animals that are feared among some people (like snakes, spiders and sharks) and are known to be deadly.

Cassandra
Cassandra can be portrayed as either a horse (because of her relationship with Fidello) or infuse her with a horse, to make her a centaur (seen in Centaur AU) or portrayed as an owl (due to her relationship with Owl) or have owl like abilities. Fans have also placed as a cat.
