Radio Waves allows Tomura to disrupt radio waves and cause communicators to malfunction.
The Quirk can also be used to awaken Nomu from a distance through an induced current.
Tomura utilizes this Quirk in conjunction with Air Cannon to create a wide-range blast that can shut down communications used by Heroes. This blast had a secondary effect of awakening several incomplete High-End Nomu which Tomura had prepared nearby.
