I watched an old Hercules cartoon, in the storyline, Hercules returns to Thebes and finds out his hometown has been attacked by another kingdom. After assuming his loved ones were gone, he goes on a quest to become a God. He meets Ulysses on the way, and goes to Tirens to hear about his one major quest, to slay the 9 headed Hydra.
I think the cartoon was supported by Anchor Bay Entertainment. It was an old cartoon.
