Stock

Stock (ストック) is the quirk used by the villain Garvey.

Description
Stock allows Garvey to absorb attacks and store them up to release whenever he wants. To do this, he must "devour" the enemy's attack, and once this is done, a lump grows in his back. When he needs it in battle, the lump detaches from his back and floats until he stands in front of his face, releasing the attack that was stored there.
