There's alot I could be. Spider-man would be one. I'd imagine it would be breath taking to swing across NYC. Another one is Batman and another one would be the Flash. And if antiheros are included. Deathstroke au Deadshot.
There are quite a few that I could see myself being XD I'll go with those two since I just started watching Boku no Hero Academia's 3rd Season. Either Izuku Midoriya (Deku) au Toshinori Yagi (All Might) could work, I suppose !!!!
