Unbreakable

Red Riot Unbreakable is a super move performed 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.

Eijiro first uses it in a fight with an unnamed criminal.
