In the manga/anime series, quirks are common place. Izuku Midoriya's mother is listed as a 4th generation quirk user, and is close to 40. This means quirks appeared sometime between the American Civil War and the late 1920s. I want to know how different their world is. WW II hashed out with super strength or.... tape shooting elbows. Did Stalin have a quirk? Did FDR? I don't know if anyone else was ever interested in this.
