Denki Kaminari is a boy whose Quirk is Electrification, which allows him to absorb and emit electricity. Overuse of this ability will cause his brain to "short circuit", severely reducing his cognitive functions for some time. Denki is a friendly, social, and energetic boy who likes to hang out with people. He is rather casual when interacting with others, although he's also not above petty complaining or overreacting if feeling annoyed or shocked enough. 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), sometimes accompanying Minoru Mineta on his schemes and 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. Denki is also a bit of a jokester and likes to tease others with playful comments. Overall, it seems that Denki has an interest in appearing cool and trendy to impress people, but has a shallow understanding of how to do so properly. Because of that, he gets easily influenced by what's popular or stylish at the moment, even if it's due to villain action. 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 to normal.
