Synopsis for "I Learned the Monstrous Secret of Bombu!"
Two men flying over the Amazon lose control of their plane and are taken from the crash site by natives to their witch doctor, Bombu. Bombu claims he is an immortal alien who landed on Earth long ago to gather information for an invasion. The men scoff at Bombu's story, angering him and provoking him to demonstrate his various powers. However, the men are still sceptical, thinking that they are being hypnotized to see things that aren't there. Bombu loses patience and creates a bottomless pit with which to destroy them, but at that fatal moment, he is struck by lightning and killed. The superstitious natives take this as a sign that the two men possess greater power than Bombu and guide them to safety.

He has the ability to swap bodies with the man, is telepathic, and even though he is in disguise as the man's body he can prevent the stronger Martian form from attacking him. The man in the Martian's body is helpless to do anything to challenge the Martian, but when the ship is about to land, he looks over the crowd and thinks of them all unarmed so that the Martian rush them with his pistol and defeat them.
