Izuku's journey as a hero began in earnest when he enrolled in U.A. High School's Hero Course, a prestigious institution dedicated to training the next generation of heroes. It was here that he befriended a group of students with diverse Quirks, each with their own unique abilities and personalities. Katsuki Bakugo, with his explosive Quirk; Ochaco Uraraka, who could manipulate gravity; and Tenya Iida, with his super-speed Quirk, among others, formed a tight-knit group that supported Izuku through the trials and challenges of hero training.
