Denki Kaminari

Denki Kaminari (上鳴電気, Kaminari Denki) is a student at Yuuei training to become a Pro Hero.

Appearance
Denki has blond hair with black, lightning-shaped strokes, and small thin eyebrows.

Denki's hero costume consists of a black jacket, that he wears open, with lightning patterns, a white shirt underneath, a belt, black pants with a lightning pattern running down each leg, and a headset.

Personality
Denki is a smooth talker and is kind of flirty. He is quick to panic, and just as quick to brag if it can make him look good in front of his female classmates.

When he overuses his ability he loses all forms of his personality and devolves into a giggling lunkhead.

Ultimate Space & Jams Arc
When Denki tries to evacuate Yuuei High, he complained about the people. Denki is warped to the mountain side of the Ultimate Space and Jams along with Momo Yaoyorozu and Kyouka Jirou. He tries to call for help, but to no avail. Kyouka then kicks him into one of the villains, causing the villain to be electrocuted. One of the villains try to attack him, but is stopped by Kyouka's Quirk. Momo then creates a insulator sheet which hides her and Kyouka, allowing Denki to use his Quirk to its fullest and discharges a great amount of electricity against the villains, defeating the villains without harming Momo and Kyouka. However, one of the villains ambush him and takes him hostage, forcing Momo and Kyouka to stop and do nothing. However, the villain holding Denki is shot down, freeing Denki. He is then seen with his class after the battle with the Villain Allaince is over.

Sports Festival Arc
After Shouta announces that the Sports Festival is approaching, Denki says that he plans to become a professional Heroes's sidekick after he graduates, to which Kyouka states that many people become sidekicks and fail to become real Heroes, to which she thinks that Denki is the kind of person who would become like that, which crestfallens Denki. Denki competes in the Obstacle Race where he places 24th, allowing him to compete in the next event, the Human Cavalry Battle. He teams up with Shouto, Momo and Tenya. Shouto explains that Denki will be on the left, using his Quirk to shoot sparks to prevent other from getting too close to them. After the Human Cavalry begins, Denki and his team confront Izuku and his team.

Shouto orders Momo to prepare an insulator sheet and tells Denki to prepare to release his electricity. Shouto covers himself along with Momo and Tenya with the insulator sheet while Denki releases a huge amount of electricity, electrocuting and stunning the other teams attacking them. Afterwards, Shouto immobilizes the stunned teams by freezing their legs. Shouto takes one of the headbands of the teams while charging forward to fight Izuku's team. Fumikage's Dark Shadow tries to attack Shouto but Momo uses her Quirk to block the Dark Shadow. Shouto's team continues fighting but Izuku's team proves to be quite resilient. With only a minute left, Tenya tells his team to hold on tight as he uses his move Recipro Burst to forcibly accelerate his movement to blazing speeds allowing him and his team to speed past their enemies in a blink of an eye which catches Izuku's team off guard and allows Shouto to grab Izuku's 10 million headband in the confusion. Unable to move due to the Engine stall of Tenya's move, Denki and his team are forced to fight Izuku's team for the remaining minute of the Human Cavalry Battle.

For the last ten seconds of the Human Cavalry Battle, Denki discharges electricity against Izuku's team, but Fumikage uses his Quirk to block. The ten seconds are up and the Human Cavalry Battle ends. Denki's team places first which allows him and his teammates to participate in the final event.

Denki is seen eating lunch during the noonday break. Afterwards, he and Minoru trick the girls of Class 1-A into doing the cheering battle, saying it is a message from their homeroom teacher. After the girls of Class 1-A walk out in their cheer leading outfits, Denki and Minoru hold thumbs up in their success. After Denki and Minoru tricked the girls into wearing cheerleader outfits, he is partaking one of the recreational events before the final event starts. The final event is a tournament event and Denki's opponent in the first round is Ibara Shiozaki. After Izuku defeats Hitoshi, Denki comments to Katsuki that Izuku used the same overthrow that he used on him, to which Katsuki tells Denki to shut his mouth.

During the first few seconds of his first match, Ibara wraps her vines around Denki, preventing him from moving and using his Quirk. Panicking, Denki tries to escape using his Quirk, but ends up short circuiting himself as a result, which causes his defeat and is eliminated from the tournament.

Denki, sitting next to Hanta, comments that Katsuki's reaction speed makes it impossible to distract him, saying that Ochako's Quirk only activates when she touches her target and against Katsuki's fast reflexes, the odds are against her. After Eijirou returns to watch the match between Izuku and Shouto, Denki congratulates Eijirou for making it to the second round.

After the match between Fumikage and Katsuki ends, Denki agrees with Hanta's comment about Fumikage winning, saying to Hanta that he also thought Fumikage would win.

Denki along with his class watches the closing ceremony of Yuuei's Sports Festival.

Two days after the Sports Festival, Denki is in class. During the Hero Informatics period, Shouta shows the Pro Hero nomnations, revealing that Denki received 272 Pro Hero nominations. Afterwards, Class 1-A have to decide on Hero names. Denki has some trouble thinking of a name until Kyouka gives him an idea, to which he comments on her intellectual idea. Denki comes up with a Hero name: Stun Gun Hero Chargezuma (スタンガンヒーロー・チャージズマ).
