Monkey D. Luffy is a 17-year-old boy that defies the standard definition of a pirate. Rather than the popular persona of a wicked, hardened, toothless pirate who ransacks villages for fun, Luffy's reason for being a pirate is one of pure wonder. The thought of an exciting adventure and meeting new and intriguing people, along with finding One Piece, are his reasons for becoming a pirate.
