Wanna grab something to eat when we're done here? I'll be happy to console you if you want. Because this match will probably... be over in an instant.
Denki to Ibara Shiozaki in "Battle on, Challengers"

Denki Kaminari ( (かみ) (なり) (でん) () 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.


Denki has relatively short blond hair, parted to the right with a black lightning-shaped streak on the left of his side fringe, which is angled so that it partially obscures his left eye. He has slanted, somewhat triangular yellow eyes, and notably small eyebrows. He's a little skinnier than most of the other male students in his class, not having much visible muscle mass.

He wears the normal U.A. uniform during school hours, the second button of his blazer undone.

In his original hero costume, he wears a plain white shirt, over which he wears an open black jacket with a white lightning pattern across his back, and matching pants with two lines running down his legs. He has a single, square-shaped earphone over his right ear, something resembling a radio antenna sticking out of the top.

His updated hero costume consists of a slightly shorter black jacket with fewer white patterns, only two near the hem and collar, and a yellow rimmed lightning bolt going around each of his shoulders. He still wears matching black pants, but they only have a small zig-zag near each of their cuffs, and he wears a belt and a white v-neck shirt. Around his right wrist, he wears a wristband with a circular mechanism from which he can shoot disc-shaped Pointers which aid him in aiming his Quirk, and he wears a headset with blue-tinted visor, probably colored this way to cancel out the glare of his electricity.



Denki is a friendly, social and energetic boy who likes to hang out with people. He is rather casual when interacting with others, including antagonistic figures like Katsuki Bakugo. Denki may come off as blunt and reckless at times, 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 having his advances ignored or outright rejected by everyone he asks out. He is also slightly mischievous, joining in pranks occasionally. Overall, it appears that Denki has an interest in appearing cool, but has a shallow understanding of how to do so properly. As such, he gets easily influenced by what's popular or stylish at the moment.

Denki is not very academically bright, requiring help when it comes to studying due to his constant neglect of school duties. He does not appear to show much interest in classes, gets easily bored from lectures and suffers anxiety attacks when dealing with tests. Despite this, Denki can show surprising knowledge about certain areas such as literature, art and music, possessing a large vocabulary that shows up every now and then. His overall lack of wit and tact often results in Denki looking like a fool in front of others, making him a common victim of snark, in particular from Kyoka.

Denki becomes quickly distraught when put into stressful situations. During combat situations, he is very quick to panic, leading him to accidentally activate his Quirk in the face of any imminent danger and leaving himself vulnerable in the process. He becomes more reluctant to use his full power when there are allies close to him, being afraid of hurting them through collateral damage from his volatile bolts. 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.

Whenever Denki exceeds his wattage limit, he loses his ability to discharge energy, with his entire personality changing into that of a giggling idiot for a certain period until he reverts back to normal. In this state, he is always giving thumbs ups, as a way to let others know that he is fine.

Electrification ( (たい) (でん) Taiden?): Denki's Quirk allows him to cover his body in electricity. He can also emit this energy, but has little control over it. Exceeding his wattage limit causes his brain to short-circuit.[1]

Super Moves

Indiscriminate Discharge 1,300,000 volts ( () () (べつ) (ほう) (でん) 130 (まん) V (ボルト) Musabetsu Hōden 130-man Boruto?): Denki releases a large amount of electricity to shock everyone around him. Despite the name, the voltage for this attack is closer to 112 Million Volts.




  • Communication Earpiece: Denki wears an earpiece on his right ear that allows him to channel his electricity and create electrical communication signals. This allows him to communicate with other channels remotely. However, signals can also be blocked out by outside electrical disturbance.
  • Sharpshooting Gear: A device Denki wears on his right forearm that fires the Pointers. It contains a dial that allows Denki to choose the pointer he wants his electricity to be directed towards in case multiple Pointers are set up.
    • Pointers: Disc-shaped projectiles that stick to targets. When Denki releases his electricity, it converges to where the released pointer is. The working distance limit is 10 meters.
    • Optical Visor: A glasses-like accessory that updates Denki with info in regards to the Pointers.

Prototype Design - Denki

Denki Kaminari's preliminary design.

  • In the preliminary stages of the series, Denki's design was radically different from his current one. He looked far more villainous, with longer, spikier hair. Also, he was not yet known as Denki Kaminari, but rather as a random electricity Quirk user.
    • This original design also shares a lot of similarities with Present Mic, who was also conceived as a completely different character from what he is currently.
  • Denki's known U.A. data is as follows:
  • Denki's popularity rankings are as follows:
  • His family name contains the kanji for above (?), sound (?), and is read as kaminari (かみなり?) the word for thunder (?). His given name is written and read as electricity (電気?).
  • Denki likes hamburgers and trendy things.
  • According to Horikoshi, Denki's role as a character is to tie the class together.
    • He also states that Denki is fun to draw, but he still cannot draw his hair consistently.
  • Denki's black hair streak is apparently natural.
  • Denki dislikes salty liquorice.


  • (To Katsuki Bakugo) "It's only been a brief while since our conversation has commenced and yet already we have been made apodictically cognizant of your personality, redolent as it is of a turd getting steamed in a sewer."
