Denjiha belongs to the EMP Bombers and, later, to Number 6. It does one thing thoroughly: dump an electromagnetic pulse wide enough to black out an entire area, stranding everyone caught inside it without power or contact. Its resemblance to All For One's Radio Waves is almost certainly no coincidence.
Rendered in Japanese as Denjiha, this long-range Emitter ability is the signature weapon of the EMP Bombers and one of several powers held by Number 6. It debuts in Chapter 51 of Vigilantes and Episode 24 of that adaptation. Tomura Shigaraki and All For One wield a different Quirk carrying the same English name, spelled differently in Japanese.
The holder generates electromagnetic pulses out of their own being, forceful enough to interfere with and disable both electricity and communications throughout a given area. Given the identical function and the users' shared links back to All For One, the two Radio Waves are widely assumed to be duplicates of one another.
The purpose-built EMP Bombers introduced the power during the Sky Egg Bombing, detonating their pulse outside the tower. The Tokyo Sky Egg went dark, and the Pro Heroes trapped within lost every line of contact with anyone beyond the building.
Number 6 later made it the foundation of the Naruhata Lockdown, releasing an electrical pulse that darkened the whole city at a stroke, unsettling civilians while sealing off outside interference with his Operation Anonymous. Running it alongside his Overclock, he also seized control of the Anonymous, pushing orders out through his parallel processing.
In the Vigilantes spinoff, the Radio Waves Quirk used by the EMP Bombers and Number 6 lets its holder generate electromagnetic pulses that knock out electricity and communications across an entire area.
The EMP Bombers' Radio Waves Quirk is powerful enough to black out the Tokyo Sky Egg tower during the Sky Egg Bombing, and in Number 6's hands it plunged an entire city into darkness during the Naruhata Lockdown.
The purpose-built EMP Bombers introduced the Radio Waves Quirk during the Sky Egg Bombing, and the villain Number 6 later wields it as well, building it into the foundation of his Naruhata Lockdown.
They are not confirmed to be identical, but because both produce electromagnetic pulses and both sets of users trace back to All For One, the two Radio Waves Quirks are widely assumed to be duplicates of one another.
The Naruhata Lockdown is Number 6's operation in which he uses his Radio Waves Quirk to black out an entire city at once, unsettling civilians while his Operation Anonymous seals off outside interference.
