Lock Down (施錠 Sejō?) is the Quirk used by Rock Lock.


Lock Down allows Rock Lock to lock objects into a particular point of space, turning the touched object effectively immobile.[1]

Rock Lock activates this Quirk through protrusions on his fingers that resemble key teeth. The Quirk is useful for stopping moving terrain, at least to a certain point.


Lock Down has a limit in terms of object force and size. It also does not affect living beings.
