The long-running My Hero Academia anime franchise has introduced a truly breathtaking variety of pro heroes and villains in the span of six seasons, some much stronger than others and some lasting longer than others. For example, the masked villain Overhaul was a serious powerhouse back in Season 4, and All Might was the #1 fighter in Season 3, but neither of them is in any shape to fight in the anime's upcoming 7th season. Powerful characters often get rotated in and out, so each season has a different roster of who's the strongest My Hero Academia characters.
