Answer:
Achilles.
Step-by-step explanation:
Achilles is the Greek symbol of the perfect soldier. He was fearless, courageous and he was practically invincible because of his superior combat skills. Besides, being a semi-divine creature, he only had a vulnerable point: his heel. That´s the origin of the phrase "Achilles´heel." Achilles is both a Greek mythological figure and a literary figure that appears in the Iliad , the epic poem by Homer.
