The user has the ability to control their own shadow, which has a sentience of its own. This shadow is capable of protecting the user from harm, as well as acting on their behalf in various ways. The shadow's appearance, form, and abilities are all subject to change based on its absorption of other life forms. At the start, it is only big enough to fit in the palm of the users hand. With enough absorption, the shadow will grow and gain significant power and influence, becoming a powerful force capable of challenging even the Endbringers. There is no known upper limit on the amount of strength the shadow can gain.
