Lock Down allows Rock Lock to lock objects into a particular point of space, turning the touched object effectively immobile. He activates this Quirk through protrusions on his fingers that resemble key teeth.
The Quirk has a limit in terms of object force and size. It also does not affect living beings.
- Deadbolt: By touching a nearby surface and performing an 180° spin with his hand, Rock Lock secures his immediate area down in a point of space. It is first used against Joi Irinaka.
