Luffy from one piece definetly deserves to be on this list for he has the 3 hakis , gear second and third. Luffy has the power of the Gum-Gum Fruit which makes him a rubber man therefore he does not feel pain from physical attacks such as punches and kicks.
Became the captain of the 11th squad by force. The Strongest Shinigami without a Bankai.
In One Piece Whitebeard is declared: "The Strongest Man in the World".Whitebeard was an abnormally large human, roughly five times the size of a normal human. He had the Power of the Tremor-Tremor Devil Fruit which allows him to create earthquakes. He protected many islands along the grand line from pirate attacks just by leaving his flag standing. Aside from his own 1600 member crew, Whitebeard had made many allies in the New World (Grand Line). Each one of the pirate captain allies were infamous pirated who had made a name for him or herself in the New World. There seemed to be at least 43 crews allied with Whitebeard. 'Whitebeard' Newgate dies standing on his feet, after having been stabbed and slashed 267 times, shot 152 and hit by cannonballs 46 times. However, for the entire 72 years that he lived, he had never once received a wound on his back because he never ran away from his battles.
Personal Opinion: It takes a real man, to stand up against a enemy nobody tried to fight head on before to save his son. He then sacrifced himself to save his crew and allies by fighting the Marines and Blackbeard to the bitter end. No more needs to be said.
