Achilles (Hercules)

Achilles is an old Greek hero who everyone except for Hercules has forgotten. He was once trained by Phil, but he failed due to his heel. He was voiced by Dom Irrera.

Role in the episode
Former student of Philoctetes who was well known as one of the greatest heroes ever due to his nearly invulnerable body, but after an incident where he was defeated by an attack to his right heel (which is the only part of his body that isn't invulnerable) he became the laughing-stock of Greece and an old washout, being forced to keep his vulnerable heel in a protective shoe. He temporarily gained his powers back, as well as removing his famous weakness in a deal with Hades but lost it again soon after.
