Luffy is the captain of the Straw Hat Pirates and is best friends with all of them and values them over all else. At first glance, Luffy does not appear to be very intelligent, often seeing things in a childish manner and can easily be amazed by the simplest things. However, because he views the world in a straightforward and simple manner, he is occasionally the only person who can see past the events and see what should be done.
Luffy seems to have an unstoppable appetite, a characteristic that is common to the Japanese archetype of the (at times simple-minded) young male hero/adventurer with a heart of gold; perhaps the hunger more so in Luffy's case due to having an elastic stomach. Luffy is also another one of the several characters given the middle initial "D."
Although Luffy is fairly lightheaded and a funny character, he has an unstoppable sense of determination, optimism, and commitment and will do anything to stand up for his friends and comrades. Along with that, he has great courage to back it up as well as unbelievable strength. Ever since consuming the devil fruit he was shown to be not worried about his inability to swim, much like his brother. Much of these traits are common among D's. His only display of true fear is towards his grandfather, to the point that he is intimidated at the mere mention of him.
Luffy never kills any of his enemies, no matter how cold-hearted they are; instead, he frequently sends the villain flying, knocking them out or beating them to a point that they are almost near death, which results in some of the villains searching for revenge, such as Buggy the Clown and Alvida. Oda explains that it's not a question of morality so much as a matter of punishing the villains for their crimes - he feels that killing the villains lets them off too lightly, whereas he considers letting them live to see their dreams be ruined a far more fitting punishment.
Luffy's dream is to find the One Piece and become Pirate King. He knows that to achieve his goal, he will have to defeat many strong opponents, including the World Government and his childhood hero Shanks.
Monkey D. Luffy is the son of Monkey D. Dragon, the leader of the Revolutionary Army and the world's most wanted criminal. His grandfather is "The Hero of The Marines," Vice Admiral Monkey D. Garp.
Before the start of the series, Dragon left Luffy in Garp's care. Dragon first appears after a lightning bolt suddenly destroys the gallows where Luffy was to be executed by Buggy the Clown and then saves Luffy from being captured by Captain Smoker. When he saved Luffy from Smoker, a mighty gust of eerie wind swept through Loguetown. It is undetermined whether or not he was the cause of the gust of wind or the lightning; however, the story leads to believe there is more to him than it seems. Recently, he has taken over an island in the South Blue and is about to head to the North Blue when he commented, after noticing Luffy's newest bounty, given to him after invading Enies Lobby, that father and son will meet sometime soon.
Some characters are funny because of all the crazy antics they get up to. But others just have the right kind of physiognomy, which make them prone to pulling off some funny anime faces - intentionally or unintentionally.
