Though Naruto certainly possesses a few skills that would keep him from being knocked out too quickly, Luffy is the winner here due to his Gear 5 essentially making physical attacks useless.

Luffy may not be a 100% underdog hero compared to shonen characters with zero supernatural powers, but Luffy still has Naruto beat in his "zero to hero" narrative all the same.

The world of anime­ has iconic characters like Naruto Uzumaki from the Naruto series and Monkey D. Luffy from One Piece. Both protagonists' adve­ntures and growth captivated fans.
