Kaido

Kaido of the Beasts is the captain of the Beasts Pirates and one of the Yonko, the third to be mentioned by name, and the last one to debut. He is one of the central antagonists of the Pirate Alliance Saga, and is known as the "strongest creature in the world". Kaido's name was first mentioned by Gekko Moriah shortly after he obtained Luffy's shadow. His title of Yonko was revealed just after the Straw Hat Pirates defeated Moriah. Kaido is an incredibly large and muscular man, appearing to be roughly three times the height of Eustass Kid, who is 205 cm (6'9") tall. Bare-chested, he sports a cross-shaped scar on his right abdomen, and a tattoo resembling reptilian scales on his left arm, with a skull at the lower forearm. He has a thin face, with thick lips and a small, hooked nose. Kaido appears to be middle aged, sporting crow's feet around his nose and eyes. Furthermore, he has incredibly long, black hair that forms defined locks resembling dreadlocks (which gives the impression of a thick mane), a very long fu-manchu mustache, and a spiky goatee, along with long, curved horns from the sides of his head. He wears a thick white rope as a belt, known as shimenawa, pants that have yet to be seen more clearly and spiked bracelets.

He bears a striking resemblance to Oars and Little Oars Jr., sporting horns that look like theirs, as well as massive hair that flows from his head to his back. His horns, mustache and hair also seem to resemble Avalo Pizarro's. From what is shown, Kaido is a merciless and confident warrior who never lets an opportunity slip by, as evidenced by his plan to attack Whitebeard during the latter's attempt to save Portgas D. Ace from execution. He apparently craves excitement, as he prepared to start the largest war in the world because he felt it was too mundane. This recklessness coupled with his inability to die has caused Kaido to make attempting suicide his hobby. He is also pitiless and not open to negotiations or excuses, which makes it seemingly unwise to provoke or underestimate him. This is enforced dramatically when Donquixote Doflamingo, a former Shichibukai and former World Noble known for his fearless and confident attitude, was very afraid of Kaido when he became potentially unable to fulfill his end of their business deal due to Trafalgar Law holding Caesar Clown hostage One of his crewmates later stated that Kaido would get very angry once he heard the news of the SMILE Factory's destruction. It was stated by Scotch that Kaido has a favorite island, a winter island that was guarded by the cyborg and visited by X Drake. Kaido cares somewhat for his subordinates, or at least values Scotch, as Scotch confirmed that Kaido would be angry if Scotch were to be attacked. As one of the Yonko, Kaido is one of the strongest pirates in the world. He attempted to take Whitebeard's life, which is something that few would dare, and clashed with Shanks. He also once fought against Gekko Moriah of the Shichibukai and emerged victorious. Being a Yonko is in and of itself a testament to his power. It was also stated by the Gorosei that he is one of the few people capable of stopping Blackbeard. According to Law, he is "the strongest creature in the world" insinuating that he is not even human, and it is suggested that he can easily kill Doflamingo, who is a world famous pirate and a Shichibukai who has a crew as powerful as the Donquixote Pirates under his command. Further testament to his strength is that Law speculated that even with an alliance with the Straw Hats, their chance of defeating him is only about 30%.

Perhaps the greatest sign of Kaido's strength is his inability to die. He has been caught and tortured 18 times, and people have attempted to execute him 40 times. However, he mysteriously survived every single attempt because every single execution weapon has broken when being used on him. Kaido also managed to singlehandedly sink nine huge prison ships. Most notably, Kaido has jumped from 10,000 meters in the sky onto the ground, creating a massive shockwave strong enough to sink a large ship nearby, and emerged without a single injury. It has even become a hobby for him to attempt suicide only for it to fail. Similar to the other Yonko, Kaido also seems to have many underlings and allied pirates and is able to claim islands as his own territories. With Caesar and Doflamingo as his associates, Kaido has created an army of over 500 Artificial Zoan-class Devil Fruit users. During Kaido's life, he had been defeated seven times and was captured eighteen times by the Marines and the Yonko, causing him to live as a criminal. During those captures, Kaido was given the death sentence forty times. However, no execution device was effective on him, and Kaido managed to sink nine massive prison ships. At one point in his life, he fought with Gekko Moriah and defeated him in the New World. Though the details of the battle have yet to be fully explained, it was implied that he is responsible for the death of Moriah's original crew. Sometime within the last four years, he began collaborating with the Shichibukai Donquixote Doflamingo and the rogue Marine scientist Caesar Clown to create an army of artificial Zoan Devil Fruit users. When Whitebeard attempted to save Ace from his execution at Marineford, Kaido tried to attack him. However, Shanks intercepted Kaido before he could reach Whitebeard. It is unknown how their encounter ended, but Shanks arrived unscathed at Marineford by the end of the war. Kaido went up to Ballon Terminal, where he encountered Urouge, who learned of his intention to attempt suicide and allowed him to proceed. Kaido jumped off the Sky Island and landed 10,000 meters below on the Kid Pirates' base. However, he was unharmed and found himself face-to-face with the Kid, On Air, and Hawkins alliance. He then began yelling that Doflamingo needs to make preparations for battle, and promised to start a massive war since he became bored with the world.
