twin

After he died, he was born again as Monkey D. Luffy — but not the Luffy everyone knows. In a different One Piece world, he has a special Devil Fruit power called the Tsuki Tsuki no Mi, a Paramecia-type ability. Then, he was sent to the real One Piece world, where the original Luffy is the captain of the Straw Hat Pirates. He joins the crew as the secret tenth member — Luffy’s twin brother. He often says with a wide grin,"You think I’m rubber? Nah, I’m moonlight!” P.S. The cover and the one piece characters aren't mine but the idea is.
