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.
- This move is similar in nature to Red Gauntlet.
- Tetsutetsu's pose while performing his super move is essentially the same as Eijiro's when the latter performed Red Gauntlet for the first time.
