Eustass Kid

Eustass Kid (ユースタス・キッド Yūsutasu Kiddo), known as the "Captain" is an infamous pirate. He is one of The Eleven Supernovas who are all renowned pirates on Sabaody Archipelago whose individual bounties are greater than 100,000,000 when the Straw Hats arrive in the place. He owns the highest revealed bounty that is still active, higher than Luffy's bounty by 15,000,000, and the third highest number seen so far in the series, after Donquixote Doflamingo and Gecko Moria. The reason his bounty is so high, is because his crew has caused huge numbers of civilian casualties in the course of their activities.

Appearance
Eustass Kid is a man with no eyebrows, dark colored lips, and black-painted nails. He has a flame-like red crimson hairstyle and a pair of square-framed goggles lined with miniscule bolts that extends with a "nose" that covers the ridge of Kid's actual nose. He wear bright green pants with a black netting like pattern and, what appears to be, a pair of sea boots. His appearance seems to be influenced on Heavy Metal musicians.

Around his waist he has a rather large bright blue scarf and belt where he keeps several knives, and what appears to be a gun. He also has gold bracelets around both wrists.

He wears a furred captain's coat that is adorned with spikes on it's sides. He typically wears this coat with his right arm in it's sleeve and his left arm under the coat itself.

Personality
Eustass Kid is notorious for causing a huge amount of civilian casualties. He is generally either angry or making sarcastic jokes. When he feels that he's been insulted, he is quick to resort to violence, attacking Scratchmen Apoo apparently for staring at him (in the anime, Apoo also flipped his finger at Kid's direction).

Despite his violent nature, he knows how to restrain himself when in a tight situation. He is also not blind to the way the World Nobles act, remarking that compared to them pirates are almost humane in nature and that they at least have good sides.

You know on the path we've been traveling up until now... Saying a thing like that would just get you laughed at. Although... I slaughtered anyone and everyone who had the nerve to laugh at me...!! But from here on out... we're gonna be sailing the sea where anyone without the nerve to say something like that is as good as dead...!!

-Eustass Kid

Kid has the same dream as Luffy, to find One Piece and become the new Pirate King. Because of this, and Luffy's recklessness, he seems to have a great deal of respect for him. However, while they often encounter the same problems, Kid deals with them in his own way, apparently killing everyone who ever laughed at his ambition. He also seems to believe that possessing the determination to achieve the impossible is necessary to survive in the New World.

Devil Fruit
Kid possesses some kind of Devil Fruit power connected to magnetism. He initially uses this power to repel incoming cannonballs with his left arm, propelling them at high speed back toward the attackers. Later, he used his power to steal hundreds of weapons from attacking Marines and various metal objects from all over the auction house, which gathered and connected to his right hand, taking the shape of a giant arm (much like Luffy's Gear Third), that even seems to have fingers. This effectively makes him impossible to defeat with metal weapons such as swords.

He, along with the rest of his crew, also showed flawless resistance to the Haki fired by Silvers Rayleigh at the Auction House.

Sabaody Archipelago Arc
After a long voyage following one of the Log Pose routes of the Grand Line, Kid and his crew came to the Sabaody Archipelago to prepare themselves for the New World. While there he had a little squabble with Scratchmen Apoo in Grove 24. Before their battle could escalate further, Apoo asked Kid to postpone it until they got to the New World. Knowing what would happen if an incident were to happen, Kid agreed to Apoo's terms.

Kid, along with his crew, then ventured deeper into the mangrove and entered the Human Auctioning House. As Kid waited for the auction to begin, he made a number of remarks to his crew, claiming that the World Nobles make pirates seem humane by comparison and bemoaning the twisted nature of the world order, before noting that he may actually join in on the slave auction. Kid later caught a glimpse of Trafalgar Law, who was already sitting for the auction, and received a rather rude hand gesture from the doctor.

As the auction began, Kid noticed some members of the Straw Hat Pirates come in, and was disappointed to find the captain wasn't around. Kid watched through most of the auction, until the World Noble Carlos Sei made an outrageously high 500,000,000 Beli bid for the mermaid Camie, which completely shut out the other participants in the auction. Seeing the noble go unchallenged, Kid decided to leave the Auction House, considering it another example of what's wrong with the world. However before he and his crew were out of the building, Luffy and Zoro crashed through the wall right next to them. What followed next then was a ruckus caused by Luffy that caught Kid's eye. As the events unraveled, Kid, along with the rest of the crowd, watched in shock as Luffy punched the World Noble, Carlos, out of anger for shooting his Fishman ally Hatchan. While most of everyone in the auction house started panicking at this turn of events, Kid, as well as Trafalgar Law, on the other hand, simply smiled at what happened.

Just as Kid was watching the chaos that was being caused, he noticed that someone suddenly came out of the back of the auction house's stage along with a giant. He then witnessed the person take out nearly everyone in the place except for the Straw Hats and their allies with a "Rush of Spirit". Having taken the blast and survived through it, Kid realized that this person was none other than Gold Roger's first mate, Silvers Rayleigh. As the situation continued, Kid and those still conscious realized that a bunch of a Marines were now surrounding the auction house for what Luffy did. Though happy at seeing how crazy Luffy was as the rumors stated, Kid decided to not stick around to fight a Marine Admiral. Seeing as how the Marines were treating Kid's and Law's crews as if they were accomplices to the Straw Hats, Kid told Luffy and Law that he'll go on ahead and clear a way for them so that they wouldn't have to worry themselves. Luffy and Law however were insulted by Kid's remarks, and instead decided to go face the Marines along with him. Together, the three captains began to fight the Marines outside the auction house with their respective Devil Fruit powers.

Current Events
After defeating the marines, the Kid Pirates were on their way to leave the island, when moments later Kid was confronted by what they believed to be Bartholomew Kuma (Later reveled to be a Pacifista). It fired the laser from his mouth which hit Kid's left leg, felling him at once. Law happens to encounter them while escaping as well and, despite Kid telling Law to stay back (which is met once again by Law's earlier threat), they both prepare to fight against the Pacifista.

As of recent has it been reported to Fleet Admiral Sengoku, that Kizaru caught 500 pirates at the Sabaody. It is unknown if Kid and his crew is amongst them.

Trivia

 * He is named after real life pirate, William Kidd
 * His surname is taken from Eustace the Black Monk, who was a pirate
 * He has been confirmed to be a boss in One Piece Unlimited Cruise.
 * When Kidd speaks of his experiences on the Grand Line, he mentions killing everyone who laughed at him.
