What warrior was stopped only because of the weakness in his heel?

The warrior known for being stopped due to the weakness in his heel is Achilles, a central figure in Greek mythology and the Trojan War. According to legend, he was invulnerable except for his heel, where his mother held him while dipping him in the River Styx. This vulnerability ultimately led to his downfall when he was struck by an arrow, often attributed to Paris of Troy. Thus, "Achilles' heel" has since become a metaphor for a critical weakness in an otherwise strong entity.
