What is the English word for an animal that transforms into a human?

There are many terms that are used in mythology and speculative science to describe this change. They include:

Dimorph - having two body types

Metamorph - changing beyond one's normal form

Morph/Polymorph - multiple forms

Transformer

Transmogrification

Shapeshifter

There does not seem to be a classical Word that in general describes the phasing of a beast into a human although there are many specific terms for humans that turn into certain beasts.
