Izuku Midoriya (緑谷 出久, Midoria Izuku) / Deku (デク, Deku)
Voiced by: Daiki Yamashita ( Anime and Vomic) ( Japanese ); Justin Briner ( English )
An initially "Quirkless" boy who aspires to be a hero, after attempting to save Bakugō from a villain, Izuku is chosen by All Might to become the ninth holder of One For All (ワン・フォー・オール, Wan Fō Ōru), a Quirk that stockpiles the user's physical strength and unleashes it as a powerful burst; the quirk can also be passed from one person to another. Eventually, Izuku finds out that One for All contains the quirks of the previous users but he becomes the first user capable of manifesting them. While he initially disliked being called "Deku" by Katsuki, as it is based from the Japanese term meaning " good -for-nothing.", Izuku is inspired by Ochaco's assumption that it was based on the word dekiru (できる, to be able to/to be capable of) to embrace the moniker and ultimately adopts it as his Hero name.
