Hades

Hades is the vengeful god of the Underworld who is the main villian in Pooh's Adventures of Hercules. In the film, He plotted to take over the kingdom of Mt. Olympus from Zeus by getting rid of Hercules many times in many ways. He met his end when trying to kill the hero through persuasion over the safety of Meg, but ended up being punched into the pool of souls never to return.
