Synopsis:
Playboy Whitney Hargrave challenges Prince Ra-Man to a duel of occult powers. Ra-Man embarasses Hargrave by exposing him as a charlatan. Angered by Ra-Man's actions, Hargrave orders his assistant Jambo to help him summon the supernatural Lord Leopard. When the creature arrives, his mighty mental powers make Hargrave his servant.

Jambo warns Ra-Man about Lord Leopard, but the Mind-Master finds the demon's mental powers to be equal to his own. Elsa falls into Lord Leopard's hypnotic trance too. Ra-Man then uses the cat charm to exchange bodies with Memakata. He locates Hargrave and forces the playboy to say the magic words that will banish Lord Leopard. Elsa, Hargrave, and Lord Leopard's other victims are then freed from their trances.
