Challenge of the Wizards

Basim, a dangerous wizard who abides in the ruins of Las Vegas, seizes a large number of innocent people and suspends them in a magical cage! Unless Thundarr retrieves The Helm of Power, an artifact that magnifies magic enormously, Basim will kill the innocent hostages. Thundarr reluctantly agrees, and must defeat the forces of Sholow, Scorpos, and Chomm, wizards who also seek the relic. Then he must figure out how to free the hostages without surrendering the Helm to the evil Basim!
