Steel Fist

Tetsutetsu Fist (徹拳) is a super move performed by Eijiro Kirishima using his Hardening Quirk.

Description
Tetsutetsu uses his iron hardened fist to break through his opponent's defenses and crush them. Tetsutetsu's steel enhanced swing is powerful enough to break clean through solid ice. Tetsutetsu first used this technique to overwhelm Shoto Todoroki in close quarters combat.
