Eustass "Captain" Kid is a character from One Piece and is part of the Worst Generation, also called the "supernovas" . He appears to be sociopathic and ruthless, as he constantly causes civilian casualties whenever he feels he is being made fun of, and he crucifies pirates in the new world asking to go to "Paradise", remarking that they were too weak and therefore not worthy of living.
Kid Appearance
Kid is a pale, muscular young man with shiny, flame-like red hair 🔥. His nose is pointed. His nails are dark in color and he has no eyebrows.
He dresses in an extravagant outfit consisting of black and yellow lizard-print pants 🦎, leather boots and a combination of a plain blue and green belt with a buckle featuring a four-leaf clover at its center. He also has a thin shoulder strap, also with tiny bolts that pass diagonally over his right shoulder and then attach to his waist, where he keeps a dagger with a Japanese-style handle and a pistol . He also has gold bracelets around both wrists.
He wears a pair of square-shaped studded goggles on his forehead, and a large fur captain's coat on his torso. The dark brown coat is decorated with points on the shoulders, bordered in brown. The collar of the coat is extremely flared and wide. He usually wears this coat with his right arm in the sleeve and his left arm under the coat itself 🧥. 
As a child, his hair was spikier and more extended, like a lion's mane 🦁. He also wore larger, rounder goggles and did not have dark lips. He was shown tinkering with a small metal robot using a wrench 🤖🔧.
After the timeskip, he is shown with slightly longer hair that appears to have been cut back. A large scar also covers a large part of the right side of his face and goes down his neck and another smaller one goes through his left eye 👁. His left arm also appears to be entirely mechanical, indicating that he lost his arm during the two-year timeskip. His outfit consists of his signature spotted pants, an open dark vest, a long dark coat that is kept draped over his shoulders, and two large belts. He appears to have become more muscular and also has scars on his right forearm, his left pectoral and on the left side of his abdomen 🩹.
Personality of Eustass Kid
Eustass Kid is known for causing many civilian casualties. He is angry or making sarcastic jokes. When he feels insulted, he quickly resorts to violence, as shown by the attack on Scratchmen Apoo 🎹, for apparently staring at him. He is very sensitive to mockery, insults and stares. He also appears to be extremely abusive and cruel even when unprovoked, such as when he crucified another defeated pirate crew just because he deemed their level too low for him to live in the new world .
Eustass kid is a fearless and adventurous individual, with a penchant for violence. According to Baron Tamago, after Kid's time wandering the New World, he destroyed two ships 🛳🛳 belonging to Yonko Big Mom's allies. This shows how fearless he is and does not hesitate to challenge a Yonko who would stand up to a pirate such as Edward Newgate. Despite his violent and aggressive nature, he knows how to restrain himself when he finds himself in an extremely precarious situation.
Captain Kid is also very cynical about the world government. He is not blind to the way celestial dragons act, noting that compared to them, pirates are almost human and kind in nature and that they have at least a charming side and do not hesitate to be honest about their faults, unlike the nobles, who justify their abuses with their inheritances granted by their ancestors.
He decides to leave the auction house after Camie is bought for 500,000,000 by a celestial dragon , remarking that it was like a metaphor for this rotten world and calling the whole affair a farce. He also says that the charade ends when the broadcast of Ace's kill 🔥 is interrupted.
Kid Luffy shares a common dream: to find the treasure left by Gol D. Roger: the One Piece and become the next Pirate King 👑 . It is thanks to this common dream and the madness of the captain of the mugiwaras that Kid seems to have respect for Monkey D. Luffy. However, although they often encounter the same problems, Kid deals with them in his own way, seemingly massacring everyone who mocked his ambition, which is somewhat the antithesis of Luffy. He is convinced that believing in the possibility of achieving the impossible is an essential thing in the new world.

Kid's story
Pass
Kid formed his own crew in South Blue 🌊. Kid's crew was a crew of very promising rookie pirates, introduced when the mugiwaras arrived in the Sabaody Archipelago two years ago.

Summit War Saga
Kid during the Sabaody Archipelago Arc
After a long journey following one of the Grand Line routes, Kid and his crew travel to the Sabaody Archipelago to prepare for the New World. During his stay, he gets into a bit of an argument with Scratchmen Apoo in Grove 24. Before this results in a scuffle , Apoo asks Kid to postpone it until they arrive at the New World. Knowing what will happen if something were to happen, Kid agrees to Apoo's terms.
Kid, with his crew, then ventures deeper into the mangrove and enters the Auction House. While waiting for the auction to begin, Kid makes a number of remarks to his crew, stating that celestial dragons make human pirates look by comparison and lamenting the twisted nature of the world order, before noting that he could actually participate in the slave auction ⛓. Kid then sees Trafalgar D. Water Law, who is already at the auction, and gets thrown out by the Surgeon of Death 👆. As the auction begins, Kid notices members of the Straw Hat Pirates entering, and is disappointed to find that the captain is not there, noting that he wanted to see how stupid Luffy is supposed to be and crazy, as the newspapers describe him, without knowing that his prayers will soon be heard.
Kid watches most of the auction, until the noble Saint Charlos makes an inordinate bid of $500,000,000 for the mermaid Camie 🧜♀️, which completely excludes the other participants in the sale. Seeing the nobleman leave unchallenged, Kid decides to leave the auction house, considering it another example of what is wrong with the world.
But before he and his crew leave the building, Luffy and Zoro crash into the wall right next to them 💥. There then follows a commotion caused by Luffy which attracts Kid's attention. As events unfold, Kid, along with the rest of the crowd, watches in shock as Luffy punches the Tenryubito 👊, Charloss, out of anger for shooting his ally Octo . While most of the people in the auction room begin to panic at this turn of events, Kid, while Trafalgar D. Water Law, simply smile in agreement with what has happened .
As Kid observes the chaos that has ensued, he notices someone suddenly appear from the back of the auction house stage accompanied by a giant . He then witnesses that this person has eliminated almost everyone in the place, except for the Straw Hats and their allies with the "Haki of Kings" 👑. Having taken the attack and survived, Kid realizes that this person was none other than Gol D. Roger's second in command, Silvers Rayleigh. As the situation continues, Kid and those who are still conscious realize that a band of Marines are now surrounding the auction house for the damage caused by Luffy. 
Although he is happy to see how crazy Luffy is as rumors say, Kid decides not to stick around to fight a Navy admiral. The Marines treat Kid and Law's crew as if they were accomplices of the Straw Hats, Kid tells Luffy and Law that he will go ahead and open the way for them so they don't have to 'worry. But Luffy and Law are insulted by Kid's words, and decide instead to go and confront the soldiers with him. Together, the three captains begin to fight the Marines in front of the auction house with their respective devil fruit powers 🍌. Luffy notices that Kid and Law both have special powers, Kid replies that his are even stranger.
After repelling the first wave of Marine attacks and dispersing them, Kid states that their plan of attack is now completely demolished. He bids Luffy farewell and states that it was nice to meet him, but promises that the next time they meet, he will not be so lenient. Luffy replies without worrying about anything that he will be the one to find One Piece. Kid and Law stare at Luffy and are even distracted by the Marines attacking him. Killer defends Kid and scolds him for not being careful .
After defeating the marines, his crew is on their way to leave the island, when moments later, Kid and his crew are confronted by what they believe to be Shichibukai Kuma 🐾 (who is later revealed to be a pacifista) . He surprises both Kid and his pirates, when he fires a laser from his mouth that hits Kid's left leg, immediately knocking him down. Law and his crew encounter them as they are also fleeing and, despite Kid telling Law to stay back (resulting once again in Law's earlier threat), they both prepare to fight the Pacifista.

Post-war arc
After the war was declared over by Sengoku, Kid comments that since the death of Whitebeard ☠, the balance of the three great powers is now modified, the New World is governed by the law of the yonko Shanks the redhead, Kaido of the hundred beasts and Big Mom "The strongest woman in the world" and the new era , of which no one has ever seen an equivalent thing.
Eustass and his crew then arrive in the New World. He reads aloud the newspaper article about Luffy going to Marineford for the 2nd time. He asks his second and right-hand man Killer what the Ox Bell is 🔔.
After Killer's explanation, Kid thinks that Luffy's message means that he was going to create the new era himself. Kid thinks it's funny and then says that Luffy really knows how to piss people off, and even though he credits the Straw Hat Captain for being the only member of the Worst Generation to have the courage to participate in the Great War of Marineford 🔱, thus placing him ahead of the other rookies of the worst generation, he is not generous enough to let Luffy do what he wants.
He then takes Haritsu Kendiyo 's pirate crew prisoner. After the crew begs him to let them return to "Paradise" (in the first half of the Grand Line), he crucifies them using his Devil Fruit powers, saying that people with such little resolve don't have nothing to do in the New World .
Eustass Kid during the timeskip
As new pirates with a bounty of 100 million berries arrive in the Sabaody Archipelago , Kid is one of the many pirates notable for making a name for himself in the New World, alongside his compatriot X Drake 🐱 🐉, another member of the supernovas.
At one point, Kid got into a fight with the redhead's crew and was forced to replace his lost left arm with a large mechanical arm .
Recent events suggest that Kid has become much more powerful, going so far as to destroy two of Big Mom's allies' ships , seemingly without regard for revenge from the ruthless Yonko.

After seeing his fellow Supernovas Luffy and Law captured, Kid then leaves the show at Killer's instigation to meet some guests. He then tells Killer that watching is meaningless and that he doesn't think Killer should work as a broker anyway. Kid also says he is surprised to see that Law was up to something all along, as he thought he had become a government dog 🐕🦺. When he asks if people have arrived yet, Killer says yes and that he is surprised they came. Before entering the room, Killer reminds Kid to be friendly, which irritates the Captain who tells him to shut up. Opening the door, it is revealed that outside are Scratchmen Apoo and Basil Hawkins .
Apoo finds himself standing in a ruined room and over one of Kid's badly beaten subordinates, telling Eustass that he longs to see his hideous face. Kid instantly becomes enraged, wondering what gave him the right to trash someone's lair. Apoo replies that when he is invited by the enemy, he expects a fight and that he had suspected that there might be a sniper somewhere. As the two confront each other, Hawkins declares the encounter stupid and leaves. Killer asks him to wait while he is between Kid and Apoo, reminding them that the three teams came together to try to form an alliance and asks them to at least try to discuss it. A newspaper later reveals that the three captains agreed and formed an alliance .

He prepared to discipline them by putting them in the mouth of his hippopotamus 🦛. However, Kid and Luffy quickly knocked out Dobon and his hippo. Later, Kid overheard Caribou telling Luffy a rumor about how his arm was cut off, and he stepped in to correct the story. Kid and Luffy then argued over which of them would knock out Kaido.
Later, Kid escaped from the prisoners' mine. Kid then saw Killer being escorted to the prison mine. He attempted to attack the escort, but was overpowered and recaptured.

After the Straw Hats crew seized the entrance, Kid and his pirates resurfaced, still determined to take the lead of Kaido 🐲 instead of Luffy, to avenge Killer at the same time.
While deep inside Onigashima, Kid was not prepared for the arrival of Monkey D. Luffy and Roronoa Zoro who made noise and were spotted by Apoo who then decided to attack them. While Apoo was distracted by his fight against the Straw Hats , Kid attacked Apoo in revenge.
