Unbreakable

Red Riot Unbreakable is a super move preformed by Eijiro Kirishima using his Hardening Quirk.

Description
Eijiro reaches his maximum hardening level by turning his entire body extremely hard and rugged, leaving him with a monstrous appearance and practically invulnerable to most forms of attack. This form can only be maintained for around 30 to 40 seconds.

This ability is first used during Kirishima's battle against a villain using a power up drug in chapter 133. The ability is used again in his fight with Fat Gum against Kendo Rappa.
