Horned King

The Horned King (voiced by the late John Hurt) is the main villain from Winnie the Pooh's Search for The Black Cauldron. He plotted to take over Prydain and the rest of the worlds with the power of the Cauldron and the cauldron-born that would spawn from it.  His plan was, however, foiled when Gurgi jumped into the cauldron in order to stop it's dark powers. The horned king, soon, followed when the cauldron sucked him inside and disintergrated him into a skeleton during this time.
