All For One (Quirk)

All For One (オール・フォー・ワン) is a quirk used by Sensei.

Quirk Description
Al for One allows the user to steal other peoples quirks and renders them their own. The user of the quirk is also able to transfer the quirks he stole to other people. However, not all of the people who get quirks from All for One are able to handle the strain and become mindless dolls who are not able to speak. When a quirk gets transferred to someone who already had a quirk, a mutation can occur and the two quirks blend together.
