Octoblow

Octoblow (オクトブロー) is an Ultimate Move performed by Mezo Shoji using the Dupli-Arms Quirk.

Description
Mezo uses his Quirk to grant himself dozens of arms simultaneously, allowing him to unleash many blows at once and defend himself from enemy attacks.

Mezo first uses this Ultimate Move to counter Pony Tsunotori's Thunder Horn attack by grabbing or breaking the various horns she sent flying at him. He later uses it during his fights against Chimera and Nine on Nabu Island.
