Denki Kaminari (上かみ鳴なり電でん気き Kaminari Denki?), also known as Stun Gun Hero: Chargebolt (スタンガンヒーロー・チャージズマ Sutan Gan Hīrō Chājizuma?), is a student in Class 1-A at U.A. High School, training to become a Pro Hero.

Electrification (帯たい電でん Taiden?): Denki's Quirk allows him to generate electricity and cover his body in it. While he can also emit this energy over a distance, Denki has little to no control over it, meaning it will go everywhere indiscriminately.
