Eustass Kidd

Both Kid and Killer grew up together, so they share a close bond that goes back to childhood. Kid refers to Killer as his partner and is aware that the latter is sensitive about his own strange laugh, which is why, despite being unaware about Killer having eaten a defective SMILE, he knew something was wrong with his subordinate. This was enough for Kid to attempt a reckless rescue of his friend, which led to his second capture from the Beasts Pirates after managing to escape the first time. Killer has displayed immense loyalty for Kid multiple times; it was due to Kid's life being in danger that Killer ate a defective SMILE fruit and became a subordinate of Kurozumi Orochi, showcasing extreme loyalty for Kid. Another notable instance of this happened during the war against the Beasts Pirates at Onigashima, when Hawkins managed to link his life to Kid's, which forced Killer on the defensive so he would not accidentally kill his captain, even begging Hawkins to take his life instead as long as he left Kid's alone. Killer usually acts as the voice of reason for his captain, making sure Kid stays focused and does not lose sight of his goals due to impulsiveness.Killer also provides Kid with useful information whenever the latter displays curiosity in a certain topic.

Kid seems to have a good relationship with his crewmembers that have been revealed. Killer keeps his captain calm when he gets angered. Wire and Heat hold high respect and concern for their captain. According to Basil Hawkins, Kid's crew was forced to work under the Kurozumi Family and the Beasts Pirates, with the life of their captain being used as a bargaining chip. After becoming Kaidou's prisoner, Kid was noticeably worried about what had happened to his crew and tried looking for them around the first time he escaped from the Prisoner Mine at Udon. Once he was freed for the second time thanks to Luffy's efforts, he still prioritized finding the rest of his crewmates and stated that he would only trust them from now on, as a result of Apoo and Hawkins' betrayal.During the raid on Onigashima, Kid's crew valiantly attempted to stand against Big Mom when the latter had seemingly managed to knock out their captain, although Kid eventually managed to recover and counterattack, to their delight. They also tearfully celebrated their boss's win against Big Mom and kept loyally protecting him even when it seemed like Kaidou had gained the upper hand over the alliance.

Despite this stubbornness, Kid has shown moments of maturity, willing to put his pride aside to work with his fellow Worst Generation members in overthrowing the Emperors of the Sea.Kid is shown to be quite cynical about the World Government. He is not blind to the way the World Nobles act, remarking that, compared to them, pirates are almost humane in nature and honest about their faults, unlike the Nobles that justify their abuses of power through ancestry.a After Camie had been sold in the Human Auctioning House to Charlos, Kid declared that the whole affair was a "farce" and similarly held a similar point of view regarding the broadcast of the Summit War of Marineford, calling it a "charade". For this reason, he felt amusement and catharsis when the world noble Charlos was punched down by an irate Luffy

Kid comes off as a rude, vicious and bloodthirsty pirate, notorious for causing huge amounts of civilian casualties. Whenever feeling like he is being mocked or insulted, even though a glance, he is quick to resort to violence. In fact, Kid can be so violent that he considers the choice of not immediately killing someone in his direct vicinity an act of gratitude. He also seems to be cruel even when not provoked, crucifying another defeated pirate crew just because he deemed them too weak to roam around in the New World.[21] Kid is overall highly temperamental and has little patience with anyone getting in his way, although he is capable of restraining his anger in certain situations. Kid can also be very petty, having killed countless civilians for merely mocking or laughing at him for his dream of being the Pirate King, killing several pirates in the New World for being weak, and attempting to kill Shanks' fleet solely to goad the Emperor to fight him.Kid is very prideful of his reputation and aims to reach a top spot in the world of piracy, which he plans to achieve by beating the Four Emperors, even if it means dying for it. That said, Kid has no interest in utilizing weapons of mass destruction (although he is curious about their existence) or other tools that could help him achieve those goals, instead just preferring to confront them head on with his own power. Because of this, he dislikes joining forces with others and sharing his targets with them, thinking that they will just interfere in what should be his fight alone. He also hates being the subject of false rumors that paint him in a negative light, being quick to clarify them if he overhears someone talking about him. Because of his pride, Kid is notorious for being unreasonably stubborn, unwilling to back down no matter how impossible the task is.

Kid is a tall, muscular man with light skin and slightly long spiky bright red hair, resembling flames. His nose has a particular shape, being quite pointed and having little protrusions on both sides. He has dark reddish colored lips, orange eyes, no eyebrows or facial hair, and his fingernails are painted black all of the time. He also has a large scar that drags from the left side of his forehead, goes down his neck and another smaller one that goes through his left eye. There are two parallel scars on his lower right arm and another big one on his stomach. He lost his left arm to just above the elbow during the two-year timeskip in a battle against the Red Hair Pirates first mate Benn Beckman, and until his imprisonment by the Beasts Pirates, he replaced it with a mechanical one that is somehow connected to his nervous system, shown by the presence of several metallic wires embedded directly into his skin.His attire consists of his trademark spotted pants, a black opened vest, held down by a belted war kilt. He also has a long dark red coat, worn over his shoulders. He appears to have become more muscular and also has scars on his right forearm, left pectoral, and on the left side of his abdomen.
