The power to
transform into or have a physical body made up of crystal or crystalline substance. Variation of Earth Mimicry. Technique of Crystal Manipulation.
User is made up of or can transform their body completely into crystal or crystalline substance. Users' transformed form is either anatomically identical to their normal form, aside of being made of crystal, in which case, it contains all to organs and is somewhat vulnerable to attacks. Alternately, the user can transform into homogenous matter, without any part of their form being more important than the other.
Users of Sound Manipulation may be able to shatter the crystal.
While hard, many crystals have flaws that may be used to shatter them completely. This may be true to the users of this power also.
