Avatar: The Last Airbender and Sequel Series The Legend of Korra take Mix-and-Match Critters to ridiculous extents. The series initially had a few hybrid animals among those that just looked slightly different from real ones, but they became more of the norm as the series went on. Interestingly enough, most animals in the material world are hybrids, while the majority of spirit animals seem to be real animals. Eventually, it's evident that the Gaang are confused by the very presence of a regular bear. Regular dogs and cats seem to exist however, and aren’t uncommon.
- The Team Pet, Momo, is a flying lemur (it has wings similar to a bat's).
- Earlier designs of Appa, the other Team Pet, a flying bison, are a mix between a bison and a manatee, only with six legs. Appa's final design, while still only called a "bison", doesn't quite resemble any real animal, being a large white furry Cartoon Creature with six legs.
- Boarcupines are recurring creatures resembling huge boars bristling with porcupine quills.
- Turtle ducks have duck heads, tails and legs and bodies hidden in a turtle shell. Secretly, they're Zuko's favorite animal.
- Ostrich horses are flightless birds with beaked equine heads, and serve as the main means of travel before the invention of air-balloon and cars.
- Badger-moles are giant burrowing animals and the original earthbenders (which makes sense considering both badgers and moles are excellent digging animals).
- "The Boy in the Iceberg": The "penguins" have four flippers and otter-like faces and tails. They are only called "penguins" however, similar to Appa.
- "Zuko Alone": The farm has almost every common meat animal, albeit mixed with a pig.
- "The Waterbending Master": There are "koala otters" (creatures with sea otter bodies and koala heads) living in the waters around the Northern Water Tribe.
- "The Southern Raiders" has a plant example with a tomatocarrot. This is a particularly odd example, as other fruits and vegetables — melons, mangoes, eggplants, cabbages, apples and so on — have shown up completely unaltered.
- "Sozin's Comet, Part 2: The Old Masters" has Aang making a reference to "a spider-fly caught in its own web".
- "Appa's Lost Days" has a shot of a Jackalope. Appa also encounters buzzard wasps, wasps the size of a condor with a turkey vulture's head.
- "City of Walls and Secrets": A "train" powered by earth benders passes by a herd of fox antelopes.
- Catgators: catfish/alligator crosses. Kept as pets by the waterbenders of a swamp region.
- Goat gorillas are white-furred apes with hoofed hind legs and horns.
- Tiger seals are pinnipeds with stripes and feline heads.
- Saber-tooth moose lions are giant moose with saber teeth and paws instead of hooves.
- Sparrowkeets are part-sparrow and part-lorikeet, in practice resulting in a fairly standard small songbird.
- Wolfbats resemble wolves with bat wings and faces, allowing the chase prey on land and in the air.
- "The Western Air Temple": Badgerfrogs are large amphibians with badger-like striping.
- "The Runaway": A dragon-moose with an ungulate body and a draconic head is seen drawing a cart.
- During the series finale, Toph, Sokka, and Suki ride on an animal called an "eel hound" which is renowned for its speed over both land and water. It's supposed to be a hybrid of greyhound and eel, but in effect it resembles a four-legged dinosaur.
- A subversion are the elephant koi; despite their name, the only elephant-like attribute of theirs is size. Otherwise, they just look and act like normal koi.
- "Snail-sloths", though not seen, is used as a phrase to indicate slowness or laziness.
- The "elephant-rhino" is similar as it is never seen, but is used as a replacement in the idiom "elephant in the room".
- Rat vipers are hybrids between vipers and rats, used in a proverb similar to our own "two-headed snake". Particularly interesting since rats are a viper's main diet.
- Aang meets an ancient giant lion turtle posing as an island, who teaches him the art of energy-bending.
- Hippo cows resemble holstein cattle with hippo heads. Despite being composites of two herbivores, the apparently like to eat meat.
- A pirate captain is encountered with a parrot iguana on his shoulder (which in effect makes it look more like a prehistoric dino-bird like Archaeopteryx).
- "Tales of Ba Sing Se": A turtle-seal, a seal with a turtle shell on its backs, is seen padding along at the back of a stampede of zoo animals and providing some Mood Whiplash. The escaped animals also include a swarm of dragonflies, lizards with insect wings, an armadillo tiger, and a group of "hog monkeys" (which resemble baboons with porcine faces).
- Koala-sheep are incredibly docile balls of fluff that make great pillows.
- Rabaroos look like giant marsupial rabbits. The one shown also has three babies in its pouch, way too many for a kangaroo but a small litter for a rabbit, implying that the mixing goes beyond external features.
- Korra's Canine Companion Naga the polar bear dog, just as giant as one might assume.
- Bolin's pet fire ferret Pabu, is a mix between a ferret and a red panda, with the general appearance of a red panda, and the elongated body of a ferret.
- Pigeon-rats and lizard-crows (lizards with corvid wings and heads) scavenge in Republic City's urban sprawl. Additionally, spider-rats seem to be a pest problem.
- The bounty hunter, June, rides upon a creature known as a shirshu which resembles a cross between a star-nosed mole, a giant anteater, and a wolf, with the shared attributes of these components. It has an incredibly acute sense of smell, no apparent eyes, paralytic venom (which moles do possess), and a long, lashing tongue.
- Bolin once mentions a "poodle-pony" which is apparently a pet species.
- Korra uses a comparison to a "weasel-snake" as an insult.
- Bolin mentions that Eska threaten to feed him to "dolphin-piranhas".
- The animal companion of the first Avatar, Wan, was a cat-deer, specifically a hybrid of a caracal and a pronghorn (which isn't really a deer).
- In Season 3, Korra, Asami and the crew of a downed airship are chased by a giant sand shark that looks like the cross between a Great White and a Sarcastic Fringehead.
- Dragons combine the overall shape and spiritual connection of Asian dragons with the wings and association with fire of European dragons.
- Averted by the Earth King's pet bear Bosco. That's it. Just a bear. And unlike the "penguins" from the first episode, it looks and behaves exactly like a real bear. The others are confounded by this information.Aang: You mean, platypus bear?
Katara: No, it just says "bear."
Sokka: Certainly you mean his pet skunk bear.
Toph: Or his armadillo bear.
Aang: Gopher bear?
Katara: Just "bear."
[Beat]
Toph: This place is weird. - Platypus-bears aren't just something Katara said in the above quote. They're seen beforehand, thus creating the oddity of a Mix-and-Match Critter that has another Mix-and-Match Critter as one of its components.
- An Expanded Universe comic has scorpion bees.
