Kraken

Kraken (クラーケン), full name Vast Hybrid Chimera: Kraken (混成大夥 キメラ・クラーケン), is a Super Move performed by Tamaki Amajiki using his Manifest Quirk.

Description
Using his mastery over his Quirk's feature selection, size variation, and simultaneous manifestation, Tamaki mixes his Quirk to its maximum conflagration. He arms himself with layers of shells for protection, including a mask over his face. Then he unleashes a massive tentacle attack that releases multiple giant tentacles that attack in a rotating wave.

Tamaki first used this technique to combat Toya Setsuno, Yu Hojo, and Soramitsu Tabe of the Eight Bullets.
