About the Monster Girl Encyclopedia Wiki

The Monster Girl Encyclopedia Wiki is an online community dedicated to the Monster Girl Encyclopedia (MGE) franchise, a compendium of knowledge concerning monster girls, commonly referred to as MGs or mamono, created by Japanese artist Kenkou Cross.

Monster girls are lewd, female variations of creatures found in the traditional mythologies of various countries, religions, histories, and cultures. Information on each monster girl, like their habitat, diet, and disposition, is dispensed through "profiles", all available here on the wiki.

In addition to canon content, the wiki hosts a variety of fan fiction and 'What Would You Do?' scenarios.

Different parts of the wiki fall under different rule sets but our Global Community Rules apply to every part of the site, including Discord chat.

The Monster Girl Encyclopedia Series

Monster Girl Encyclopedia I and all monster girl profiles are written from the in-world perspective of a travelling scholar, wandering the MGE world while documenting the various creatures and features he comes across. Since the release of it's initial encyclopedic volume, the MGE franchise has grown to encompass an entire world setting, centered around the on-going conflict between the religious zealots of The Order of the Chief God and the Demon Lord and her monster army.

Monsters are what this wiki is widely known for. These creatures can be born as monsters or turned from human to monsters. They are always female and target both males and females for various reasons in various ways depending on the myth they are based on.

New Monster Girls can be seen added about every two months.

Lore/books and what to read first:

The wiki features Lore behind the Monster Girls. This is information about the world they and others live in and how different factions, flora, fauna and culture have affected on one another.

Fan-made Content

The wiki features a large fan base which means a lot of fan-fiction and fan-lore is written for the setting on points that aren't clear for the reader. Fan-fiction contains stories written about one or several lead-characters that experience the Monster Girl world. Even with this being an 18+ restricted site, highly detailed graphic descriptions of sexual or violent acts are prohibited. All fan-work is to be posted as blogs apart for the fan-made monsters.

The fanfiction on the wiki consists of two categories.

Series are a multitude of stories that either are a continuation of one-another or all belong to the same story line. Fanfic Series

One-shots are stories that aren't part of a continual series. Fanfic One-Shots

The wiki has people who write fan-lore about the world and its contents. This is the author's view of the world and may conflict with the factual information given by the maker of the Monster Girls. Fanlore

Users enjoy thinking up their own Monster Girls. These are to be posted here for convenience - if placed elsewhere they will be removed. Fan-made Monsters
