In that case, after looking at powers on the superpower wiki. I found one I might use. Basically, my character would be able to create and control golems from a substance they are able to secrete from their skin. While also able to coat their body in said substance to act as armor and to buff their melee attacks. That is all I have at the moment, other than the limits of how many golems they can control at once or how long it takes to make one.
