Agathon was a character on Xena: Warrior Princess. Ares gave him the secret for creating the Metal of Heaphestus, of which he used for his army. Xena put together a small band of men, consisting of people that she knew in her past to bring him and Ares down. He was then killed by Xena. Somewhat ironically for a villain, "Agathon" is derived from the Greek word agathos, meaning "good".
