Amplivolt

Written in Japanese as Zōden, this Meta Ability carries the same name as the villain who wields it. The Emitter classification fits its habit of taking a modest jolt in and sending a long-range attack back out. Readers meet it in Chapter 263, and the anime introduces it during Episode 115.

Amplification, not creation, is the whole idea. Current that enters the body gets conducted, stacked up, and finally let go through the hands once it has been raised to a level worth firing.

Charging requires an outside supply. Nothing here sparks current from nothing the way Electrification does, so the user shocks himself with a taser to prime the ability. Hand him more tasers and his output ceiling climbs accordingly.

Electricity running through his body injures him not at all, a resistance he demonstrates plainly by tasing himself without flinching. Once the charge is built high enough, it exits through his palms as blasts.

The counter is anything thirsty for current. Objects or Quirks that draw and conduct electricity, with Electrification the clearest example, can swallow the discharge whole and leave nothing to land.

The villain Amplivolt is the sole known holder. He brings the ability out when a hero army storms the Gunga Mountain Villa, opening with Supreme Discharge: Thundernet, the most powerful technique in his arsenal, hoping to stop the assault where it stands.

That move starts with a taser jolt to the hand and finishes as an enormous spread of current washing over many opponents together. It fails anyway: Denki Kaminari, fighting as Chargebolt, absorbs everything through Electrification and lets his allies press on.
