Hybrid

Hybrids can't be found in the wild, but breeding certain pairs of Nephelym has a 40% chance to give birth to a Hybrid (Marked as such by the presence of the Hybrid Trait).

You need to buy the Mutt Hut from Cassie before you can get Hybrids; otherwise, pairs of Nephelym which would normally produce a Hybrid will only produce non-Hybrid offspring.

All Hybrid variants produce Hybrid Semen (which can be used to catch Slimes) and Hybrid Milk.

Note that the Griffin, Kujata, and Unicorn cannot be bred without at least one Futa parent, as their parent races have no male variants.

Trivia

 * Since "Hybrid" is considered to be a species, this makes it the one species in the game with the most unique variants, at a total count of 19.
 * This is compared to the Bovaur and Sylvan species, which are tied for second place with a relatively meager 4 variants each.
 * Despite this, none of the Hybrid variants are male - only female (and, by extension, futa).
 * The Nephelym species with the most hybridization options is the Demon, which has 7 unique hybrids in total.
 * Not including the Hybrids themselves, there are a total of 9 Nephelym variants which have no related hybrid species: Shark (Formurian), Bunny (Risu), Carrier/Seeder/Spore (Starfallen), Goblin/Orc/Slime (Sylvan), and Bee (Thriae).
 * The Griffin, Kujata, and Unicorn cannot be bred without at least one Futa parent, as their parent races have no male variants.
 * Much like the common Nephelym species, many Hybrid variants are based on mythical or fantasy creatures.
 * The Akabeko (Literally "red bull" in Japanese) is based on a legendary cow of the same name, which was said to be present at the building of a Japanese temple in the year 807 CE. Some stories say the cow turned to stone after giving its spirit to a Buddha, while others say it simply refused to leave the temple grounds and became a permanent fixture there.
 * The Amaru seems to be based on the Amaruca (also known as Amaroca or Katari), a mythical dragon/serpent that appears in the Andean civilizations of South America. The Amaruca is often depicted with a motley mix of features, such as feathered wings, avian feet, a serpentine tail, and the heads of both a bird and a puma.
 * "Bakaneko" (Literally "idiot cat") is a likely play on the "Bakeneko" ("changed cat"), a supernatural monster in Japanese myth which takes the form of (and usually appears by evolving from) a normal cat. The roles of different bakeneko in Japanese legends vary, but they were often mischievous at a bare minimum, and had a wide range of powers which ranged from speaking Japanese words to possession and shapeshifting.
 * The Basilisk is based on a mythical European beast of the same name. While older representations of the mythical basilisk paint it as a relatively standard-looking snake with venom of such supernatural potency that its gaze could kill, depictions shifted gradually towards a visual of the basilisk which melds features of a snake and a rooster.
 * The "Catsune" is a play on the term "Kitsune," referring to supernatural foxes which are frequently seen in Japanese folklore. The roles that kitsune play in individual Japanese myths are widely varied, but they tend to fall somewhere within the bounds of mischievous and benevolent, and all have the ability to shapeshift into a human form, along with varying other powers.
 * The term "Daeva" may be in reference to any of several different sorts of godly beings from a few early Middle-Eastern and Asian religions:
 * "Daevas" in Zoroastrianism are harmful celestial beings, described early on as "gods that are (to be) rejected," and later on as promoters of chaos and disorder.
 * "Devas" in Hinduism are godly manifestations of all things good, standing in contrast to their negative counterparts known as Asuras.
 * "Devas" in Buddhism are celestial beings which are stronger, longer-lived, and generally happier than humans, but are not quite as revered as Buddhas.
 * Ultimately, the Daeva's representation in-game may be in reference to the contrast between these different mythical beings, being a hybrid of a Seraphim and a Demon in reference to the stark contrast present between the "good" devas of Hinduism and Buddhism and the "bad" daevas of Zoroastrianism.
