Mimicry

Mimicry is a Quirk that is used by Irinaka, also known as Mimic from the Eight Precepts of Death.

Description
This Quirk allows Mimic to transfer his own body and mind into solid objects, and manipulate them as though the object was his actual body. Under normal circumstances, the size of the object that this Quirk is said to be useable on are no larger than a refrigerator, but when his Quirk is boosted, presumably by the drug Trigger, the Quirk is capable of manipulating entire locations.

Mimic mostly uses his Quirk to inhabit a small, black cloak, which he uses to move around and interact with others.
