The User is able to transform their body completely into metal. Users transformed form can be either anatomically identical to their normal form, aside of being made of metal, in which case it contains all to organs and is somewhat vulnerable to attacks. Alternately user can transform into homogenous matter, without any part of their form being more important than the other.
User gains varying powers depending of what kind of metal they mimic: some metals are soft but malleable and survive damage by flexing under the attack and returning back to their normal state afterwards, others are hard and can take severe damage before eventually breaking. Metals have also varying abilities relating their ability to tolerate/conduct heat, electricity, acid/corrosion, etc. Several metals have specific symbolic and mystical properties.
