Mitsuo encountered Superman, an alien belonging to a federation that strives to maintain peace in the galaxy. He subsequently received a helmet (which also functions as a mask) granting superhuman strength, a cape enabling flight, and a badge allowing him to breathe underwater and communicate with fellow comrades he met shortly after using these gifts. Superman made it clear to all Permans that their identity must remain secret, or their brains would be destroyed if it were ever revealed. To help achieve this, they are given a special doppelganger robot that can replace them while they are away, although it is not entirely foolproof nor free from potential problems. These items then allowed them to become young Permans who try to maintain peace and help people in need.
