Heartbeat Distortion (ハートビートファズ Hātobīto Fazu?),[1] full name Amplifier Jack: Heartbeat Distortion (音響増幅 (アンプリファー) ジャック: ハートビートファズ Anpurifā Jakku: Hātobīto Fazu?) is a Super Move performed by Kyoka Jiro using her Earphone Jack Quirk.


After Super Move Training, Kyoka upgrades her costume with two new wrist amplifiers. She can plug in her Earphone Jack's into the amplifiers and release sonic waves into anything she touches with them. The waves produced were strong enough to break up the ground.[1]
