Izuku's quirk is Sound Cancelation. It's a passive Emitter type that uses an opposing soundwave to cancel all sound in an area. That's it. At least at first look. Due to the way it works, that means Izuku is capable of producing said sound waves. With training, it is possible to use that mechanism to attack with soundwaves of various strengths, similarly to Present Mic's Voice. It is also possible to turn this quirk off, but when unconscious that is not possible.
