57 VarietiesIn science fiction and fantasy, there are lot of different species. Often they interbreed, however implausible this is (for multiple reasons). One result of this is Half-Human Hybrids, but in other cases things get a little more complicated. For some characters, not being too fussy about species runs in the family, with the end result being a sort of multi-species grab bag. (One common definition of "species" is a group in which interbreeding can produce fertile offspring — try not to think too hard about it.) Sometimes the Science Fiction version of But Not Too Foreign, Ambiguously Brown. A common trait of a Mary Sue, and/or a Munchkin, but not in itself a damning marker, as it can frequently be played for comedy or barely mentioned. Or the writer may deploy Hybrid Overkill Avoidance to avert the problem entirely. See Ninja Pirate Zombie Robot for when the Rule of Cool takes this to another level. For combinations of only two species, see Half-Human Hybrid, Non-Human Humanoid Hybrid, or for second-generation hybrids and on, Uneven Hybrid.

Anime and Manga
- Slayers: Zelgadis is 1/3rd human, 1/3rd golem, and 1/3rd "blue demon" (whatever that is, often identified as Mazoku). This is the result of Functional Magic. note
- Bleach: There are four souls, representing four races (Shinigami, Hollow, Quincy, Human), each with their own set of special powers that defines them (Shinigami, Hollow, Quincy, Fullbring). Ichigo is a natural hybrid of all four souls, due to his parents experiencing unnatural events before he was born. He is a "substitute shinigami" because his Shinigami power seemingly manifested first. His Quincy power manifested first, masquerading as Shinigami power; Aizen hollowfied his Quincy mother, whose life was stabilised by Isshin's Shinigami power. Ichigo inherited Quincy, Hollow and Fullbring power from Masaki, and Shinigami power from Isshin (both directly as his son, and indirectly via Isshin's power being used inside Masaki's soul).
- From a widely circulated list of music history jokes:
"Handel was half German, half Italian, and half English. He was very large."
- This piece of Dragon Ball Z fanart making fun of the various Mary Sue characters that are a bane to DBZ fanfics.
- In Child of the Storm, Harry's father is Thor (who was incarnated as James). This means that he's half Asgardian. So far, so simple. Except that he was conceived his father was a human wizard, leaving him with three sets of biological grandparents. Furthermore, Thor is one quarter Titan thanks to Bor, Odin's father, marrying Theia. Lily, meanwhile, was a witch and a latent mutant, and, to complicate matters further, it's implied that the Asgardian side of the family intermarried with the House of El a very long way back. No one's quite sure, and in any case, the genetic influence would be minimal. And, as it turns out, all this confluence of heritages really seems to succeed in doing is giving Harry a few Psycho Active Powers that, at best, he has limited control over, and a headache when it comes to trying to figure out his family tree.
- In Snow Angels, a Haruhi Suzumiya fanfic which is now deleted, Kunikida turns out to be part Humanoid Interface, part Time Lord, part Saiyan, and part Vulcan. His son adds being half-human to that.
- From Memory Gamma, a Star Trek fanon wiki, the Warship Voyager version of Rachel Leslie. Part human, part Klingon, part Andorian, and part Cardassian. Apparently done by use of Borg nanoprobes to alter her DNA.
- Fans of My Little Pony: Friendship Is Magic have produced quite a few. Most common are Satyrs, the offspring of a human and any character from the franchisenote which are basically human from the waist up and pony from the waist down. There are also Kirins the offspring of a pony and a dragon, Hippogriffs the offspring of a pony and a gryphons(which are in fact canon), and strangest of all the eerily cute Tatzlpony, a hybrid of a pony and that huge worm thing from Three's A Crowd. Basically if there are two different species in this show, you'd better believe a hybrid has been made of them. Naturally, centaurs are also a thing.
- For a specific fan example from My Little Pony: Friendship Is Magic, we have Badumsquish who is very fond of creating hybrids from the series. Among others he's hybridized a pony with a toaster and a lamp, a human with creatures such as timberwolves and windigos, Fluttershy with a squirrel, Applejack with applesauce, and for the absolute oddest example, Rarity with one of the dress monsters from Do Princesses Dream Of Magic Sheep. Unsurprisingly, he's a big fan of Tatzljack as well.
- In The Monster Club, interbreeding between vampires, werewolves and ghouls is how you get a "shadmock" like the one in the movie. Additional examples are named (raddies, maddies, shaddies, mocks), but not shown.
- J. R. R. Tolkien's Middle-earth has the so-called Half-elven family, which contained several Elf-Human intermarriages, and has also a divine Maia ancestress. Members later got to choose to be counted among the Elves or Humans (which results in (im)mortality and a different fate after death) so as not to give the Valar a headache trying to figure it out how to treat them. The two lines of intermarriages resulted in the twins Elrond and Elros, who respectively chose Elfdom and Humanity. Their daughter Arwen and distant descendant Aragorn later rejoined their lines once more.
- Aragorn and Arwen's son Eldarion beats them all; he has the blood from all three elven clans, and that of the human lines of the West, as well as Maia blood. And all those bloodlines are via royal families, meaning Eldarion is royalty amongst all High Elves and Elf-Friend humans, in the entire world.
- When asked how was that possible, the Professor gave this explanation (it's all in one of his Letters): Biologically, the bodies of Elves and Humans had to be the same, otherwise they would not be able to reproduce. The Elf-Man difference was not organic, but spiritual. Elves had been made by Eru to be bound to the world and unable to leave it by dying (even their bodily death is followed by either reincarnation, becoming a ghost, or eternal imprisonment in the Halls Of Mandos), while Men had been granted a short life and their spirits must leave the world after dying. This is why an Elf-Man hybrid can be given a choice of what would happen to them after death.
- Older Than Dirt: Gilgamesh is somehow 1/3 human and 2/3rds god. We know his lineage (goddess mother, human father who became part-divine in life), and it would make him 1/4 human, 3/4 god. It never seems to get translated like that, though.
- For what it's worth, the original author(s) thought that genetics worked like that, so the modern translations, while incorrect in terms of biology, are accurate linguistically.
- Genetics do work like that. He may have been 1/4 Human, 3/4 God by heritage, but the DNA he got from his father could have been anything from all Human to all God. If it happened to be 1/3 God and 2/3 Human, then his total genetic makeup would be as described.
- For what it's worth, the original author(s) thought that genetics worked like that, so the modern translations, while incorrect in terms of biology, are accurate linguistically.
- Xanth is full of characters like this. Thanks to the influence of "Love Springs" note , the magic of the realm taking care of any chromosome issues, and various magic spells compensating for any extremely incompatible pairings, such mixed critters are actually fairly common.
- For example, Esk is half human, one quarter ogre and one quarter nymph. He marries a living statue called a brassie, and their children are one half brassie, one quarter human, one eighth ogre, and one eight nymph. Esk's grandchildren are set to be even more complicated given their love interests- his son is engaged to a shapeshifting human half-dragon.
- Some are actually common enough to become established species in Xanth, such as winged centaurs, who come from various combinations (one being a cross between a centaur (human/horse cross) and a hippogryph, which is itself another Heinz Hybrid, being a horse/gryphon cross), and the mer-naga, which are a cross between mermaid (human/fish) and naga (human/snake).
- Taken to extremes in one novel when the characters pass through a number of alternate Xanths in search of one particular alternate, basing their assessment of whether or not they've made it on who Jenny Elf married and the resulting "species" of her daughter. In one universe, she was half-skeleton. (its a long story...)
- Taken to its Logical Extreme on one of the moons of Ida, where only interspecies pairings are fertile- combinations encountered there include a Goblin-Harpy-Dragon-Sphinx...thats the part of his pedigree that he remembers anyway.
- In Glen Cook's Garrett, P.I. novels, hybrids between the various fantasy races have become so common that the ancestry of some of them can be almost impossible to guess. Really complex blends are referred to as "uniques".
- Star Trek Expanded Universe and Novel Verse:
- Sonek Pran is one quarter Betazoid, one quarter human, one quarter Vulcan, and one quarter Bajoran. He refers to himself on one occasion as a "quadroon", an old term that didn't necessarily have that meaning and was often racially offensive.
- One world called Helena, values diversity, to the point where the more different species you have in your ancestry, the more honored you are. If you're all one species, though, you will have to use that other, less attractive dining hall, among other things. (Naturally, and ironically, Tuvok gets to experience that.) They'd be very happy to meet Mr. Pran, if he doesn't turn out at some point to actually be from Helena.
- Kirk's son in the Star Trek Shatnerverse books has 1/4 Klingon, 1/4 Romulan, and a strange mix of human ancestry from Kirk and his Chalchaj'qmey mother (an artificial Klingon/Romulan hybrid race with the addition of human organs). Additionally, according to Spock, the boy's Romulan ancestry also makes him part-Vulcan. Interestingly, Joseph Kirk's unique genetics make him an Ancient, among those who seeded most of the galaxy with life.
- Commander Phillipa Matthias, a minor recurring character in the Star Trek: Deep Space Nine Relaunch books (also appearing as ship's counselor of the USS Enterprise-F in Star Trek Online), is mostly human but has a Vulcan grandfather. She's married to a Bajoran named Chon Sibias and has two children with him.
- Played for Squick in "Auguren", a subterranean segment of the Brian Lumley novel Iced On Aran. Possibly a parody or Take That about Lovecraft's miscegenation hang-ups, it describes the systematic crossbreeding of captive human perverts with tick-men and giant parasitic worms, generating increasingly-deformed monstrosities.
- Vurt does it in fives—most of the Five Races can have sex with the others, but there are only five combinations that produce viable offspring. Some of those can interbreed to produce five possible three-way combinations, and those can interbreed to produce five possible four-way combinations. Of course, there's only one five-way combination, but so far one of those has never been born. (This makes no sense from a genetic standpoint, of course, but a): cyborgs apparently pass down their robotic limbs to their children, and b): human plus dog is a viable two-way pairing. They Just Didn't Care, and you needn't either.)
- Pollen goes into a little more detail on the matter. The source of the whole thing was a sort of fertility plague released from the dream world... men afflicted with it would pretty much go out and inseminate anything that seemed like a good idea at the time. Whether this was an intentional side effect was unclear.
- Dark Reflections Trilogy has Merle, whose mother is a sphinx, and father a demon/human hybrid. Despise this she looks completely human.
- In On Fairy-Stories, J. R. R. Tolkien warns of the dangers of this being a muddier and less impressive creature the more parts get spliced in.
- In M.C.A. Hogarth's furry fantasy web serial/novel Flight of the Godkin Griffin the Godkindred Kingdom believes that by interbreeding they can become gods, the ruling caste, known as Godkin, have ten or more bloodlines. Angharad Godkin (the eponymous griffin) is part coatl, crane, fisher, hawk, lion, phoenix, puma, ringtail cat, Siamese cat, and snake.
- Tales of MU:
- Coach Callahan is a Dwelgrorc (quarter each Dwarf, Elf, Ogre, and Orc). The Dwarf and Elf Quarters are from different parents, of course.
- Ceridwyn "Puddy" Banks-La Belle claims to have Dwarf, Giant, Dragon, Sidhe, and Nymph blood, mostly for scholarship benefits (and the dwarf exemption to campus alcohol regulations).
- In Making Money, Moist is asked to guess what breed Mr. Fusspot is, and can only manage to say, "Er, all of them?" He's half "spoon hound," but whatever else he is is unknown.
- The recurring character Nobby Nobb is the subject of massive speculation about his ancestry due to his appearance. He eventually becomes a card-carrying human. Not figuratively; he was always human, he just now literally carries a card to prove he's human. In later books there's speculation he might be part goblin, and he's apparently fairly attractive by their standards.
- Eric introduces (and extroduces) the demon god of the Tezuman empire, Quetzovercoatl, the Feathered Boa. Half-man, half-chicken, half-jaguar, half-serpent, half-scorpion and half-mad (a total of three homicidal maniacs).
- Bair from Mithgar is one of these, known as "the impossible child". His bloodline is a mix of elf, human, Mage, demon, and probably one of the various breeds of Spawn, though this is never confirmed and if so which kind is never stated. Bair's dad, Urus, from whom he gets most of these bloodlines, is a less extreme example. It's explicitly stated by Dalavar the Wolfmage that it's the contribution of the demon and its inherently magical blood that permits all this hybridization; in most cases the different races in this 'verse are infertile with each other.
- Star Trek:
- A time travel episode of Star Trek: Enterprise had a dead body (from the future) with Genetic Material from most of the eventual-Federation's species, and the (living) time traveller Daniels said he was Human "more or less" (meaning he's probably 50% human and 50% everything else).
- Star Trek: Deep Space Nine: In an alternate timeline seen in "Children of Time" the Defiant crash-landed on a planet in the Gamma Quadrant 200 years in the past. The crew intermarried, with Jadzia known to have married and had children with Worf. By the time of the episode the planet's entire population of 8,000 people descended from the crew are Heinz Hybrids of (at minimum) human, Trill, Bajoran, and Klingon.
- This is the fate of all of humanity in Doctor Who. In fact, it was even used as a plot point in the Eighth Doctor comics - Humanity's genetic template had been so corrupted and augmented by interaction with various alien species by some point in the future the Cybermen eventually noted their cyberconversion process just didn't work on most humans anymore, forcing them to raid the past for viable converts.
- "End of the World" has Lady Cassandra, "the last human" (who at this point is a sheet of skin with a face). When Rose gets a moment to talk to her, Cassandra explains that at this point the entirety of what would be called "human" has one alien or another in their ancestry, and thus she's only "the last human" by her Fantastic Racism standards. Rose doesn't stand for it.
- The song "Misconceptions" by Mercedes Lackey parodies it — "My mother never talks about that orgy..."
- Expansions in the card game Munchkin allow players to be "Third Breeds," three races at once.
- Taken Up to Eleven by the "Chimera" card, which permits the player to equip one or more of each race card.
- Dungeons & Dragons:
- The Orcs of Thar contains rules for interbreeding of humanoids. 2/3rds of offsprings from such breeding are the same as one of the parents, while the last are considered hybrids. Ability scores, appearance and other racial features are randomly determined among the two parents (although 2/3rds are generally the same species as one of the parents)
- One of the races is mongrelfolk, which is exactly what it sounds like, descended from slaves of pretty much every human, demihuman, and humanoid race. (Depictions of them in 2nd edition with tentacles or lobster claws have been quietly ignored.) They range from being able to pass for human to incredibly twisted wretches, though most are pretty much decent people regardless of appearance.
- Thanks to the proliferation of creature templates in 3rd edition, it was possible to start with a half-orc or half-elf character and slap on template after template, including half-dragon, half-fiend, half-celestial, half-elemental, and half-troll, to get an impossibly mixed up character with incredible powers (but only one hit die).
- The 3.5E Forgotten Realms: Underdark supplement has the baphitaur, a cross between a tiefling (Uneven Hybrid of human and fiend) and a minotaur. The fluff text notes this to have been done by magical experimentation rather than sexual reproduction.
- In the Neverwinter Nights 2 expansion pack, Storm of Zehir, non-lawful, non-good humans can chose two heritage feats at level one, allowing them to become part human, part demon and part fey. Then they can take the Red Dragon Disciple prestige class and become half-dragon as well.
- In Mortal Kombat, there we have the Sub Zero brothers wherein they are Chinese-American with a descent from cryomancers from Outworld.
- Potentially taken to absurd levels in Agarest Senki. If you pick properly with each generation of characters, the fifth generation's hero (Rex) will be 1/8th Human, 1/16th Syrium, 1/16th Neocolom, 1/8th Dark Elf, 1/8th High Elf, and 1/2 Harpuia.
- The second game has a more subdued example, as the third generation's hero (Grey) can potentially be 1/4 Human, 1/4 Neocolom, and either 1/2 Oneltes or 1/2 Harpuia.
- In Rune Factory 3, the main character is a half human, half sheep monster hybrid, who can switch between human and sheep forms. His possible brides include an elf, a mermaid, and a girl who is a half human, half phoenix hybrid. All of these marriages can produce children.
- Med'an, the son of Garona Halforcen and Medivh from the World of Warcraft comic. His mother is half-orc, half-draenei; his father was human. As those species all originated on different planets, his epithet "child of three worlds" is literally appropriate.
- Lydia Greyrose from Wizard101 is half farie and and the other half hasn't been said exactly other than it's not farie and that her half sisters are evil witches that live in candy houses and eat children. Her farie blood broke the Always Chaotic Evil nature and gave her wings but made her smaller than her sisters.
- In Pirate101, while not directly stated, it is implied that the rare and powerful bumbleloon are the result of a giant hornet somehow managing to breed with a buffaloon (which looks like a buffalo crossed with a balloon with a tiny set of wings on its back added for maneuverability). It's also implied this happened naturally and fairly regularly since its meat has been used to summon a powerful spirit for generations.
- Parodied with Ranger from 8-Bit Theater. After this strip it was established that he's 1/2 Elf, 1/4 Lefeinish Human, and 1/4 half-orc.note According to Red Mage's calculations, he has seventeen grandfathers, two of whom haven't been born yet.
- El Goonish Shive:
- Grace has a mixture of human, alien, other alien, and squirrel DNA. She's a voluntary shapeshifter, and an in-universe character who knows this sort of thing has mentioned that a human could impregnate her the old-fashioned way (unless she's in her human/squirrel hybrid form).
- Then there are her siblings who, like Grace, were born from the same set of alien eggs that allow the DNA of any number of any species to be combined to create a viable creature (meaning the number of combinations is practically infinite). Beings born from these eggs are called seyunolu (chimera) who can shapeshift into any of their parent's forms as well as undergo Partial Transformation. However, with the exception of Vlad/Vladia, Grace's brothers contain no actual alien DNA (the shapeshifting ability is due to the eggs). Guineas is 50/50 Human/Guinea-pig; Hedge is 75/25 Human/Hedgehog; and Vlad/Vladia contains DNA from several bats, owls, hawks and even a leopard in addition to human and alien but who cannot shapeshift without risking her life.
- Happens in Dominic Deegan. In this case it's confined to one area and is apparently caused by eating the food, so it might be that the people don't actually start out that way.
- Double Subverted in Divided Sky. While Interspecies Romance is quite common, the child's species is either that of the mother or the father. Usually. Otherwise, the person will embody this trope.
- Ogrek the Undisciplined in Yamara is one-quarter orc, one-quarter pixie, one-eighth human, one-eighth ogre, one-eighth elf, and one-eighth... something.
- Josh's character in the webcomic Chainmail Bikini is half-human, half-Dark Elf, and half-Orc. He justifies it by saying that Orcs and Dark Elves are okay with polygamy.
- Dabbler of Grrl Power claims to be one-third Succubus, one-third Doppleganger and one-third unknown alien race. She also has a few cybernetic parts including an arm and eye, and on top of all that is also a mutant, though really, how would you tell?
- Keti of Footloose is half human, a quarter werewolf and a quarter nymph.
- Elf Blood has Carlita Delacroix, who is a half-French half-Cuban half-Human half-Spirit Incarnum.
- Celeste in Last Res0rt try to breed with as many different species as possible. Veled for example is part Anyr, part human, part Vidian and part Zillan.
- In The Kenny Chronicles Tarnekis are genetically engineered human-animal hybrids for whom species appear to be mostly cosmetic. The titular character is about 75% fox (both red and fennec) and 25% cat, while his girlfriend (later wife) is half-lemming half-baboon, needless to say in the sequel series their daughter is a bit complicated.
- This is the official explanation in the Mega Crossover Fan Webcomic Roommates for supernatural abilities. One extremity is pure human (no magic at all) the other pure Fair Folk ("made of magic", extremely rare) anything between is a Heinz Hybrid (so most of the people considered The Fair Folk, the Witch Species and probably even a part of humanity). Every character can try to do the genealogical research himself if he cares what percentage fae he is (they normally don't because the magic family tree makes "1+1=<><" sense at times).
- Ellen's D&D character in Leftover Soup is a "half-celestial half-dragon half-nymph half-elf." Which she claims makes sense because half-elves are their own race.
- Ensign Sue Must Die, being a parody of Mary Sue fiction, naturally makes Ensign Sue half-whatever-is-convenient-for-the-plot. She manages to rack up quite the number of halves.
- Legion in Tasakeru is a hybrid of all eight sentient species.
- Rampant in the Furry Fandom due to Special Snowflake Syndrome.
- In Metamor City Callie Linder's mother was an ordinary human, but her paternal grandparents were an archon and a succubus. Her father's good and evil halves canceled each other out, leaving her with just the chaos.
- Coincidentally, or not, an old Brunching Shuttlecocks feature parodied this aspect of "Star Trek" with a character who was a "half-Romulan, quarter-Vulcan, one-eighth-Bajoran office manager, whose cold exterior belies a heart of utter aloofness."
- Looney Tunes:
- Parodied with Charlie the dog in a short where he tries to convince Porky to adopt him. He says he's "Fifty percent Collie, Fifty percent setter (Irish Setter!) Fifty Percent Boxer, Fifty percent Doberman Pincher, Fifty percent pointer -— there it is! There it is! There it is! — But, mostly, I'm all Labrador Retriever!" When Porky demands proof, Charlie's response is, "Just get me a Labrador, and I'll retrieve it!"
- This joke was lifted from (or lifted by?) another short featuring various breeds of dogs, with Charlie having that conversation with the narrator. Also the immortal bit, "This is a Doberman Pinscher. *pan to dopey looking soldier* This, is Doberman. *pan back* And what does a Doberman Pinscher do? *The dog gets up, puts on a mischievous face, and goes off-screen to live up to its name.*
- Ben 10: Alien Force 's first arc ends with the Highbreed ending up this way. They're Nazis IN SPACE! to the point of having genocide as a hat, being themselves a Master Race and the only ones worthy to exist. It turns out that race itself is facing extinction due to generations of inbreeding and the Omnitrix's ability to repair genetic damage was broadcast through their Portal Network in the Grand Finale of the arc. The only way it could do this: the Omnitrix AI spliced them with the DNA of every species known, mixing up their genes enough to resolve their sterility.
- The Omnitrix has done this more than once. Kevin 11 got his powers when he used his own energy absorbing abilities to try and take the Omnitrix's powers, resulting in a monster that's one-tenth every one of Ben's Omnitrix repertoire at the time.
- Adventure Time:
- In a variation, Marceline is "only" genetically half-demon, half-human but then she also became a vampire.
- While her actual appearance was reduced to an easter egg, "Ocarina" reveals Jake has a bear/dog/rainicorn granddaughter.
- Four episodes after "Ocarina"; "Joshua And Margaret Investigations" reveals Jake himself is a Non-Human Humanoid Hybrid, making all his kids dog/rainicorn/shape-shifter Heinz Hybrids and further complicating his granddaughter into a bear/dog/rainicorn/shape-shifter Heinz Hybrid.
- Modern humans. Current paleontology, anthropology, and genetics indicate that ancient Homo sapiens interbred with at least four other members of genus Homo, including the Neanderthals, Denisovans, and possibly late-surviving Homo erectus. In particular Asians, Caucasians, and Native Americans share the majority of their immunity genes with the Neanderthals, and one family line of Africans and African-Americans originating in Cameroon carries a Y-chromosome that appears to predate Homo sapiens. PBS has a 2015 miniseries on the subject, First Peoples.
- Most "mutts" you find in the local pound tend to have very colorful family trees. A dog could have had a pure Chow grandfather and Labrador mix grandmother on one side, and a Welsh Corgi/Standard Poodle grandfather and German Shepard/American Healer grandmother on the other. And, at some level, he'll likely show traits of all of them. However, it's worth noting these are all technically the same species, Canis lupus familiaris.
- F1 hybrids do exist in real life as well, though they are notorious for being sterile. Examples include:
- Mules: a male donkey and a female horse produces an animal with the strengths of both and the weaknesses of neither. Females can theoretically breed but pregnancies are rare
- Hinny: Their opposite, a female donkey and a male horse. They're also noticably harder to breed and are considered "hit or miss", and are smaller than mules due to their smaller mothers
- Liger: Yes they exist, and they are awesome◊. The offspring of a male lion and a female tiger, they're also illegal as far as deliberate breeding goes because of the dangers such an enormous animal places on a mother.
- Tigon: The opposite of a liger, a male tiger and a female lion offspring. These are also not sterile and have historically had kids of their own, but they're considerably smaller than ligers, more in keeping with the size of their Tiger parent.
- Leogar: These hybrids of male leopard and female tiger have occurred naturally in the wilds of India on enough occasions for them to rate a common name (dogla) among local natives.
- Zebroids: There are so many different ways to make a slightly different but functionally similar zebra F1 hybrid that it's easier to class them together. Zebras can mate with any other equine and produce a zebra offspring, from mules to horses, with the child having a mix of the pattern and physicality of the parents (creating horses with zebra striped legs, for example). They're also notoriously aggressive.
- Wholphin: Mating a female bottlenose dolphin with a false killer whale produces another type of hybrid, one that can produce offspring but with a success rate comparable to Krogan
- Nanulak: Grizzlies and their polar cousins can mate to produce a Jack-of-All-Trades ursa with an ashen coat that mixes those of its parents. Also nicknamed "grolar bears", they've become more common as populations of both species decline and females are unable to find mates of their own species.
- Beefalo: the offspring of cattle and bison produces a meat machine that would give Epic Meal Time a run for its money. Best of all they're fertile. Unfortunately this also means that those interested in conserving the American Bison population are having problems since cattle are so prevalent in America.
- Savannah: Child of the serval and a common household kitty. While these too can breed, they're at their biggest and most powerful as first and second generation cats, as successive generations pull a Dragon Ball and result in smaller and weaker kittens that are more like their cat side than their Serval one.
- Cama: Much like the beefalo, this offspring of a llama and a camel gives more wool than its llama parent with the temperment and domesticated attitude of the camel.
- Dzo: Dzo are the ligers of the Bos family, becoming bigger and stronger than either their yak or cattle parents. The females are also fertile, allowing the generations to carry on.
- Wolfdog: Like its name suggests, this is the child of a grey wolf and a common Dog. And since dogs and wolves are currently considered to be the same species, they have no fertility problems whatsoever. Breeding one carries all the pluses and minuses that must have plagued our ancient ancestors when they first domesticated Wolves, because these animals can vary between shy and submissive to as cunning and vicious as a regular wolf. However their strength makes them a promising means of immediately breeding out common weaknesses in purebred dogs, allowing their children to regain some of their durability and versatility at the cost of extreme variability.
- Coydogs are crosses between domestic dogs and coyotes. They do not socialize well as coyotes usually don't form large groups but can be tamed if raised from birth. In some states they are menaces to livestock and pets.
- Coywolves are fairly common, though there is some decrease in fertility. Coyotes in the Eastern states tend to be larger than 'yotes out West due to wolf genes. The red wolf is believed to be a coywolf variation that bred true and is of intermediate size between coyotes and grey wolves and formed packs bigger than coyote families but smaller than grey wolf packs, before they went extinct in the wild, fortunately there's a captive breeding program but many of those released have interbred with coyotes.
- Golden Jackals can breed with domestic dogs but because of their differing chromosome counts many hybrids are sterile. The Soviet Union bred the Sulimov dog as airport sniffers by crossing jackals with Lapponian Herders and then breeding the resulting half-jackals with Huskies to make them more trainable. Since the 70s other breeds such as Spitz's and fox terriers have been bred into the line and 40 Sulimov dogs are in existence, all owned by Aeroflot-Russian Airlines and used for security.
- At least one instance of an African/Asian elephant hybrid was born in a zoo in 1978. It died 12 days after birth from an intestinal infection. This example is considered unusual since both parent species belong to different genera.
