Lock Down ( () (じょう) Sejō?) is the Quirk used by Ken Takagi.


Lock Down allows the user 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.
