Ironskin

Ironskin makes the user's body as tough as metal. if the superpower is active, Ironskin toughens the user's skin temporarily to protect them against a single attack or in one battle. If it's passive, it will always have their skin be hardened. Melee attacks, weapons, and likely explosives will deal little if any damage to a 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 in air and sink in water faster.
