Monkey D luffy

Monkey D. Luffy (モンキー･D･ルフィ Monkī D. Rufi^?) is a pirate and the main protagonist of the anime and manga, One Piece. He is the son of the Revolutionary Army's commander, Dragon, grandson of the famed Marine, Garp, and the foster brother of the late "Fire Fist" Portgas D. Ace and Sabo. His life long goal is to become the Pirate King by finding the legendary treasure left behind by the Pirate King, Gol D. Roger. He believes that being Pirate King means one has the most freedom in the world. He has eaten the Gomu Gomu no Mi.
As the founder and captain of the Straw Hat Pirates, he is the first member that makes up the crew as well as one of its top three fighters. Luffy was one of eleven rookie pirates who had been referred to as "The Eleven Supernovas", the eleven pirates with bounties over 100,000,000 to have reached the Red Line. Luffy's current bounty is 400,000,000, as stated by the "Impostor Luffy" after the timeskip, and confirmed by one of the readings from a Pacifista. Eustass Kid also states that Luffy had taken the lead over the eleven Supernovas, implying that his bounty had raised. Later on, when the Straw Hats arrive on Fishman Island, Hody Jones also reveals Luffy's wanted poster which shows a bounty of 400,000,000.
Luffy has a worldwide reputation for causing trouble, even among the Shichibukai and the Marines, committing crimes against - as well as actions that were deemed threatening by - the World Government.
He has gained a reputation for being 'reckless' and, in some cases, 'insane', after causing an incident in Enies Lobby, entering and escaping Impel Down, and joining the Battle of Marineford. He is therefore famous for being the only pirate to not only break into the three most important government facilities, but also escape from all of them alive.
This, plus the fact that he punched out a Tenryubito with full knowledge of the consequences and his heritage has caused Luffy to be labeled as a "dangerous future element".
