Mimicry

Mimicry is a Quirk that is used by Mimic.

Description
This Quirk allows its user to transfer themselves 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 hallways.

Mimic's body seems to be rendered inoperable while the Quirk is activated.
