Dupli-Arms (複ふく製せい腕わん, Fukuseiwan?, lit. "Replication Arm"): Mezo's Quirk grants him a set of tentacles alongside his arms. He can transform the tips of these tentacles to replicate other parts of his body (ex: mouth, ears, eyes). The duplicated body parts are more efficient than the originals; as a result, Mezo is able to hear better, see-through more angles at a time, and they grant him much higher degrees of strength.
