Skullmaster

Skullmaster was the main villain of the cartoon series "Mighty Max". The archenemy of the "Mighty One", SkullMaster is an ancient fusion of warrior and sorcerer whose lust for power has driven him to destroy at least two civilizations - the Lemurians and the Atlanteans. He destroyed the Lemurians out of wrath when they wouldn't give him the secrets of the key, and he used the souls of Atlantis to power his Crystal of Souls. At some point, he was imprisoned deep within the earth, where he sealed the reigning king, Lava Lord, into solid rock and took control of his minions. During the second season, SkullMaster was free to roam the earth and proceeded to cause all kinds of trouble until he was defeated once more by the new "Mighty One" - Max.
