Monkey D. Luffy (Luffy for short) was raised by the pirate "Red Haired" Shanks. Luffy dreamed of becoming a pirate, until one day he was held back. He ate the "Gum-Gum" Devil Fruit. He became made of rubber, but for the cost of never being able to swim again. He still decided to go out on a journey as a pirate.
Luffy's Devil Fruit powers became stronger since the 1st time he ate the fruit. He now has many abilities.
