Metal Mimicry

User is made up of or can 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. Some users may even shatter after receiving enough damage, but reconstruct themselves afterwards unharmed.

Some users can turn their bodies into liquid metal, allowing them to form knives or spears to attack their enemies.
