Queen the Plague

All-Star of the Beasts Pirates as one of Kaidou's three closest confidants. Currently, he serves as the de-facto ruler of Udon, a region in Wano Country. He is also a highly skilled scientist that was previously a member of the research team known as MADS. Due to his actions and role, he is a major antagonist in the Wano Country Arc. As one of Kaidou's three closest associates, Kaidou has a great deal of trust in Queen and his abilities. They appear to have a casual standing, as Queen addresses Kaidou by his name, rather than by title, such as "Sir" or "Boss". However, Queen is loyal to his general, as he attacked Big Mom for invading Wano. Kaidou, though seeing Queen as one of his three confidants, did not hesitate in giving the lower ranking Tobiroppo a chance to challenge any All-Star of their choice to take their position, as the crew's hierarchy is determined by an individual's power. Kaidou also took joy to Queen's dismay when he told him of Komurasaki's "death", much to the latter's overwhelming sadness. As an All-Star of the Beasts Pirates, Queen has great authority over his crew just below his Governor-General. He currently has the highest authority over Udon, a region in Wano Country, and oversees the proceedings of the Prisoner Mine.

Like the other All-Stars, he is hailed as a "calamity" for his destructiveness. In terms of battle prowess, Queen is one of the Beasts Pirates' strongest warriors, implied to be strongest after Kaidou and King; with a bounty of 1,320,000,000, illustrating his fearsome reputation. Queen demonstrated incredible fighting skills in combining physical combat with his cybernetics, being capable of easily blocking one of Luffy's punches with his hand and throwing the pirate to the ground with his mechanical arm. He could fight and overwhelmed Sanji an extremely powerful martial art master until the latter gain genetic enhancements, evolving his body enough to finally defeat Queen. Queen is a veteran pirate, having been part of the Beasts Pirates for a least 20 years and even then was already considered among its strongest members. Queen is an extremely talented scientist, inventor, and mechanic who specializes in the creation of biological weaponry. Queen is skilled at developing brutal torture methods to break the spirits of the Beasts Pirates' enemies and get them to reveal information, an ability of which he is very proud. Queen is notable for having been formerly part of MADS, a rogue research team involved in several scientific discoveries and development of weapons. Queen ate the Ryu Ryu no Mi, Model: Brachiosaurus, an Ancient Zoan-type Devil Fruit that allows him to transform into a full brachiosaurus and a human-brachiosaurus hybrid at will. When fully transformed, Queen becomes much bigger and towers over even large humans like Big Mom, who stands over 8 meters tall. As a Zoan, he gains a significant boost to his physical abilities. He has tremendous durability as he has been able to shrug off powerful attacks, such as Diable Jambe kicks from Sanji, strikes from Chopper in Monster Point, his own rocket launcher misfiring on him and he was even able to quickly get back up after taking an attack from Big Mom, one of the most powerful combatants in the world. He can use the signature long neck of a brachiosaurus in combat, such as by swinging his head at his opponents, or using his long neck to reach targets that are further than he can normally reach or in mid-air. Additionally, his body weight is drastically increased in his dinosaur form and he can use this immense weight to his advantage, as very little will be able to withstand the crushing pressure of his massive transformed body. In full Beast Form, Queen also possesses the abnormal ability to detach his neck and tail from his torso, effectively allowing him to transform into a large snake with a powerful coil that he claims can crush even the most skilled users of Busoshoku Haki. Queen chased Sanji to the Pleasure Hall, where he saw a geisha named Some that he was pining for but who had continually rejected him. Angered upon seeing her, Queen turned invisible and attacked her before confronting Sanji again. Sanji decided to destroy his Raid Suit, leaving Queen disappointed. The two resumed battling, and Queen revealed that he had obtained the same special abilities that Judge had given to Sanji and his brothers as he demonstrated all of them, although Sanji landed some strikes which pushed Queen further toward his limit. Queen then emulated Sanji's given power of invisibility, but Sanji countered by moving faster than the eye could see. Queen then saw Some come back out, and went to attack her again. However, Sanji then struck him with Ifrit Jambe, a form of Diable Jambe made hotter and more powerful by his new modifications. Sanji pummeled Queen with devastating kicks, culiminating in the attack Bœuf Burst which defeated Queen and sent him flying off of Onigashima.
