Otherkin is a subculture made up of people who consider themselves non-human or having a connection to a mythical archetype in some way, usually believing to be mythological or legendary creatures. Common creatures to which Otherkin claim some connection include angels, demons, elves, fairies, lycanthropes, and even extra-terrestrials.[1][2] The otherkin community grew out of the elven online community of the early-to-mid-1990s, with the earliest recorded use of the term otherkin appearing in early 1996.[3] Outside of their own subculture, otherkin beliefs are often met with controversy.[4] According to diagnosis criteria put forth by mental health professionals, the belief that one is an animal or can be turned into an animal is termed clinical lycanthropy[5], a delusion of varying severity and significance.
