All Might

All Might, former number 1 hero, also was the symbol of peace. His real name is Toshinori Yagi, and when he gets excited, he sometimes hacks up blood. His quirk is All For One, which is a power that is passed down by generations. He was originally born quirkless. His real form is whenever he's really skinny and looks like a "walking skeleton". Toshinori once loved a woman, who he never knew was the daughter of his arch nemesis, All For One. She left Toshinori as she continued doing crimes like her father did, but no one knew she was pregnant with Toshinori's kid (you). Years later, he's walking down the street from a hero meeting. He just found out you're his kid, and that you were born with 28 quirks.
