Monster Girls are a special type of Gijinka (擬人化) / Humanization where the anthropomorphic character is a mix between a creature (both real and fictional) and a human. Which means some body parts/limbs of a creature has generally been added or switched on a human body.
The human is usually a female, though some rare male examples exist. Monster Girls can also refer to moe versions of already existing monsters, such as vampires or trolls. Fetishism of monster girls is referred to as teraphilia, and is a common form of internet paraphilia.


Since monster girl is such a broad and vague term, creators and fans often argues about its clear definition.
The general consensus is that a monster girl is a mix between a human being and a monster or an animal.
Most of them are an human torso on the top of a monster bottom body. One of the general rule is to keep the face and torso area human, with exception of cyclops and something spider, who get either only one eye or more of them.
Also, independent and more mainstream genre like Succubus and Cat Girls are sometime excluded.

The umbrella terminology of monster girl can include certain types of personifications of monsters from video games, movies, books and so forth. Mythological creatures such as fox girls or other types of humanoid creatures are often included and so forth. However while succubus and nekomimi/cat girls are mainstream it is common for succubus and cat girls to be included.


While the origins of the modern Monster Girl can be debated the idea of non-human seductresses can be traced back to antiquity. Many ancient cultures, such as the Greeks, have tales of men (and women) being seduced by mythical and mystical creatures, such as the sirens from Homer's Odyssey. Even in the eastern hemisphere there are mythological stories about would be considered monster girls seducing individuals. Examples include beings such as the Kumiho and Jorōgumo. The former is a fox who lore wise lived to a thousand years and gained the ability to shape shift into human form. It can become human by not killing humans for a thousand days or other means. The Jorōgumo is a spider that is 400 years old that similarly gains magic powers, including shape shifting. Legends about it often portray it turning into a seductive women to marry a samurai.

Majors Type of Monster Girls

Although Monster Girls come in many forms these Girls presented have the largest sub-species count and can be seen as the "parent" group. However be aware that these only represent the most popular niches of the monster girl umbrella terminology; there are well over thousands of different types based anywhere from mythology to personification of popular media and so forth.


A harpy are a mix of a human and a bird. They usually have bird legs instead of humans legs and wings instead of arms. They almost always lays eggs. They are one of the most famous and representative monster girls, second only to lamia.


A lamia is composed of an human torso and the tail of a snake. It may also come with a forked tongue. It is seen as the most popular monster girls and is often used to represent the whole genre, similar to how 'Space Invaders' is representative of video games.


A centaur is a human torso implanted on the neck of a horse. They are more commonly seen outside the fandom in mythology.

Slime/Goo Girl

These monster girls are quite an oddball among others as they are not a clear mix of an human and a monster. Instead, they are a regular slime monster shaped like a girl. They are sometime portrayed as stupid kinda akin to slime monster often being weak early game mook.


Also know as spider girl, an arachne is a human torso on top of what would be the spider's head or sometimes the abdomen. They sometimes have multiple eyes similar to the many eyes of a real spider. The mandible of a real spider are almost always absent if the torso is on the head.


An Alraune is a cross between a human woman and a plant, typically of a flowering variety. Alongside Slimes, Alraunes are one of the major non-animal monster girls.

Mainstream types

These types while not considered to be necessarily exclusive to the monster girl niche these types of monster girls are still monster girls and highly popular whether they are outside the niche or not:


Mermaid are an human upper body on a fish's tail. Much like the centaur, they are much more popular in mainstream media than in the fandom. A similar but less known monster girls is the Scylla, an human torso with tentacle for legs.


Vampire lore drastically changes from culture to culture with extensive amounts of stories and such based around them. The concept of vampires has been around since the days of the ancient Greeks, Romans, and Mesopotamian culture. The kitsune of Japanese folklore, a mythical fox quite similar to the Kumiho, can be considered a vampire due to the trait of requiring life force to survive.


Zombies are by far the most diverse lore type of monsters; they range from the generic horror movie kind to essentially just reanimated people. Trying to pin a singular type as a means of summarizing the lore is impossible. The only similar trait held by all of them is that they are reanimated individuals post mortem.

First entry on KYM by me. Kinda nervous since an entry is more serious and official than a comment, pics or video is. Probably full of grammar error, typo or just plain bad writing and still in W.I.P.
As I said, help on typo or formating is welcomed!
