User is made up of or can transform their body completely into copper. Users' transformed form is either be anatomically identical to their normal form, aside from being made of cooper, in which case it contains all 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. As a metal, copper is soft and malleable with very high thermal and electrical conductivity, all of which the user gains.
