Achilles

Achilles was the son of the nymph Thetis and Peleus, the king of the Myrmidons. Thetis tried to make him immortal by dipping him in the river Styx as a baby, although he was left vulnerable at the part of the body she held him by, his heel. He was a Greek hero of the Trojan War (as well as reputedly the most handsome of the heroes assembled against Troy) and, despite his temporary withdrawal from the battle after he was dishonoured by Agamemnon, he was responsible for the important deaths of the Trojan warrior-hero Hector, Troilus and many others. He was eventually killed by Paris with an arrow to his vulnerable heel.
