Denki is a young man with short, blonde hair that has a black lightning symbol on the left side of his fringe. He has slanted, yellow eyes and is rather slimmer than most of his other male classmates. Denki's Quirk Electrification allows him to discharge electricity and emit it out of his body in powerful blasts. This Quirk serves well in both offence and defense, as the electricity shocks anyone it comes into contact with.
