Gold Roger was known as the "Pirate King," the strongest and most infamous being to have sailed the Grand Line. The capture and execution of Roger by the World Government brought a change throughout the world. His last words before his death revealed the existence of the greatest treasure in the world, One Piece. It was this revelation that brought about the Grand Age of Pirates, men who dreamed of finding One Piece—which promises an unlimited amount of riches and fame—and quite possibly the pinnacle of glory and the title of the Pirate King. Enter Monkey Luffy, a 17-year-old boy who defies your standard definition of a pirate. Rather than the popular persona of a wicked, hardened, toothless pirate ransacking villages for fun, Luffy's reason for being a pirate is one of pure wonder: the thought of an exciting adventure that leads him to intriguing people and ultimately, the promised treasure. Following in the footsteps of his childhood hero, Luffy and his crew travel across the Grand Line, experiencing crazy adventures, unveiling dark mysteries and battling strong enemies, all in order to reach the most coveted of all fortunes—One Piece.

Mitsuo encountered Superman, an alien who is a part of a federation that tries to maintain peace in the galaxy. He then received a helmet (that also serves as a mask) that gives superhuman strength, a cape that enables the wearer to fly, and a badge that allows him to breathe underwater and communicate with his fellow comrades whom he met soon after he utilized these gifts. Superman made it clear to all Permans that their identity must be kept a secret or their brain will be destroyed should it ever be revealed and they are given a special doppelganger robot that can replace them while they are away to achieve this feat, although it is not entirely foolproof nor is it free from potential problems. These equipments then allowed them to be young Permans who try to maintain peace and help the people who are in need. (Source: ANN)
