Well, Achilles was the son of Zeus and when he was younger, since he wasn't all god, his mother dipped him into the river Styx in Hades but she forgot to dip in his heal so that was the only part of him that was vulnerable enough to get him killed. He ended up in being killed during the Trojan war when a solider (i forget which one) shot him in the heal with a poisoned arrow which was guided by Apollo.
Achilles is known as the greatest Greek hero. You can read all about him in the book about Trojan War.
