Shapeshifting is the ability to change appearance and/or body structure. Different forms include:
- Metamorph (limited to human forms, unable to change mass)
- Animorph (take on animal forms. May be able to take on the abilities of the altered form)
- Polymorph (assume any form, size, mass and appearance at will).
- Therianthrope or "were-" would transform from a human to an animal (as in a "werewolf").
