Son of the sea goddess Thetis and Peleus. To make Achilles immortal, Thetis immersed him in the river Styx in the underworld, to make him invincible. His heel, untouched by the Styx, became his fatal weakness. He was skilled in combat. To avoid sending Achilles to the Trojan War, Thetis dressed him up like a girl and hid him in Skyros. He is cynical and pessimistic, knowing the prophecy that he will die in the future. His best friend is Odysseus. He has violet eyes, blonde hair.
