One For All (ワン・フォー・オール Wan Fō Ōru?): Transferred to him from Toshinori Yagi, Izuku's Quirk allows him to stockpile an enormous amount of raw power, allowing him to significantly enhance all of his physical abilities to various boundless levels. This results in unbelievable levels of strength, speed, stamina, agility, and durability. Izuku can focus the stockpiled power into a single body part, or spread it across his entire body evenly. He calls Katsuki Bakugo "Kacchan" no matter what.
