Of course after what he showed us in Dressrosa, we had to add our hero to this list. Luffy needs no introduction. He’s the captain of the Straw Hats, son of Dragon and well on his way to becoming King of the Pirates; which to him means having all the freedom in the world.
After spending two years training with Rayleigh on Rusukaina Island, he developed and perfected Gear Fourth as well as Haki. He has superhuman strength which he developed thanks to Garp’s training. Luffy can also take incredible amounts of punishment and can keep getting up to continue fighting. He can stop a strong opponent’s attack without using Haki or his Gum-gum powers, as well as dodge and react at amazing speeds.
He uses his Gomu-Gomu powers improvisationally and rarely plans any sort of attack, but he is quick to find his enemy’s weakness and use his powers to the maximum if needed. He can combine Busoshoku Haki with his Gear Second, giving him a super-strong fire fist. Gear Third makes his limbs gigantic and he can combine it with Haki as well.
As the hero, Luffy has –almost - always fought and defeated the “final boss” of every arc, so to speak. He has defeated Enel, Arlong, Crocodile and Gecko Moriah among other strong opponents. And in Dressrosa, after a long hard battle, he defeated Doflamingo using his Gear Fourth which coats his limbs in Haki while he inflates himself up to a muscular shape. This gear also adds extra strength and speed to Luffy's moves.
I could keep going but this isn't a Luffy article, we still have 3 more to go!
Searching for companions, the exultant Luffy has set off towards the "Grand Line" with his first crew mate, "Pirate Hunter Zoro". But, along the way, they became involved in a fight between the Buggy pirate crew and Nami, the Pirate Thief. Luffy, who realizes that Nami has excellent navigation skills and knows that Buggy holds a map to the Grand Line, decides to face off against the Buggy crew! After defeating the Buggy crew's second-in-command and chief of staff, he and Zoro finally face off against Buggy! But Buggy also has Devil Fruit powers, and he seems to have known Shanks....
Luffy is a bit more vulgar in the Japanese version than he is in the English dub. Also, he only lets certain people touch or even wear his straw hat. So far he has allowed Nami to wear it when he helped her in Cocoyashi Village with Arlong.
Luffy was born on Oushi Island, and has an older brother named Portgas D. Ace, who is also a pirate. His father, Monkey D. Dragon, is also a famous pirate, and is supposedly the called the world's worst criminal. Vice-Admiral Monkey D. Garp is Luffy's grandfather.
Shanks nicknames Luffy "Anchor" when he is a child. He calls him this to tease him about not being able to swim even before he eats the Devils fruit.
