The user can morph their form via the souls of elemental spirits of nature, spirits of the long-departed, demons, angels, and deities. They can combine different souls to form new transformations for themselves or use them to create super forms or hyper forms of said synchronized spirit. The user can forcefully combine with a foreign spirit or deity if their soul is strong enough to make the souls of the spirits submit to them or defeat the spirits in battle. Some bodily transformations include all the basic forms listed under Mythic Physiology.
