Denki Kaminari (In Jpn: 上かみ鳴なり電でん気き, Kaminari Denki), also known as the Stun Gun Hero: Chargebolt (In Jpn: スタンガンヒーロー・チャージズマ, Sutan Gan Hīrō Chājizuma), is a supporting character in the My Hero Academia manga and anime series.

Kaminari is a student at the prestigious U.A. High School training to become a Pro Hero. He is a part of Class 1-A of the Heroes Studies course. Denki's quirk, Electrification, allows him to generate and manipulate electricity, although he has yet to master it.

He is voiced by Tasuku Hatanaka in the Japanese version of the anime, and by Kyle Phillips in the English version of the anime.


Kaminari has short blond hair parted to the right side of his head with a side fringe which is angled in a way in which it partially conceals his left eye. Denki's eyebrows are noticeably thin and there is a black lightning-shaped streak in his side fringe. In keeping with his general design, Kaminari's eyes are yellow.

Denki's first Hero costume consisted of a plain white v-neck shirt, an open black jacket with a white lightning pattern on the front and back, matching black trousers which had white streaks flowing vertically down them, and a single white square-shaped earphone over his right eye with a radio antenna attached to it.

Kaminari's second Hero costume consisted of a slight shorter black jacket with fewer lightning patterns, instead featuring a yellow-rimmed lightning bolt going around each shoulder. His trousers were more-or-less the same, with the exception of the pattern which was changed to small zig-zags near the cuffs. Furthermore he now wore a smaller headset with a blue optical visor, as well as a belt. On his wrist Denki wore the device created by Mei Hatsume to help him pinpoint his quirk. The white v-neck shirt was left unchanged.


Denki is a friendly, social and energetic boy. While he is rather casual when interacting with others, including even antagonistic people like Katsuki Bakugo, Denki also becomes quickly distraught when he is put into stressful situations. He may come off as blunt and reckless sometimes, but is always well-meaning.

Denki is somewhat flirtatious towards the girls of his class (and even the ones from other classes), trying to pass himself off as a smooth talker. He is not very lucky with his approaches though, frequently getting ignored or outright rejected by everyone. Although, he does seem to have a steady friendship with Mina Ashido and, occasionally, Kyoka Jiro. He is also slightly mischievous, joining in pranks occasionally. Overall, it appears that Denki has an interest in looking cool in front of others, but has a shallow understanding of how to do so. As such, he gets easily influenced by what's popular at the moment.

Denki is not very academically bright, requiring help when it comes to studying. He does not appear to show much interest in classes and tests tend to make him anxious. Despite this, he can show surprising knowledge about certain areas such as literature, art and music, possessing a large vocabulary. His overall lack of wit often makes him a common victim of snark, in particular from Kyoka.

During combat situations, Denki is very quick to panic, which leads him to activate his Quirk in anticipation. He also becomes more reluctant to use his full power when there are allies close to him, being afraid of hurting them through collateral damage. When he is assured that all his allies will be safe from his powers, he becomes more confident in his fighting abilities. He does not tolerate others looking down on him or his classmates and will defend them if necessary.

When Denki exceeds his wattage limit, he loses his ability to use his Quirk and his entire personality becomes that of a giggling idiot until he turns back to normal. In this form, he is always giving thumbs-ups, as a way to let others know that he is fine.
