Ironskin

Ironskin makes the user's body as tough as metal. if it's active, Ironskin toughens the user's skin temporarily to protect them against a single attack or in one battle. If passive, it will always have their skin be hardened. Melee attacks, weapons, and likely explosives will deal little if any damage to any user of Ironskin. The exact opposite of Ironskin is Rubberskin, a defensive superpower that makes the user's body more flexible instead of more rugged.

Restrictions

 * Ironskin makes the user's mobility suffer by a considerable amount by slowing them down, reducing their jumps' power, and making them fall and sink in water faster.
