He was the former No. 1 Pro Hero and the eighth user of the One For All Quirk, and now a staff member at U.A Academy, teaching Foundational Hero Studies. He was known to the world as the Symbol of Peace, who brought an era of peace and harmony to the world, being an ideal hero to many who admired him. He later became the mentor to Izuku Midoriya, a quirkless teenager who dreams of becoming a hero after witnessing his selfless nature, and appointed him as his new successor for One For All. After fighting against All For One where he used up the leftover embers of One For All completely to defeat All For One, All Might retired from crime fighting, and thus, ending his era. He was replaced by his rival, Endeavor as his successor as the No. 1 Hero. Despite this, All Might still assists the students and Pro Heroes in every way he can as possible.
