Kaido

Kaido of the Beasts, also known as the "Strongest Creature in the World", is the general of the Beasts Pirates and one of the Yonko (the third to be mentioned by name and the last one to debut). He and his crew currently occupy Wano Country.

He was first referred to by Monkey D. Garp at Water 7 and then directly mentioned by Gecko Moria shortly after he obtained Monkey D. Luffy's shadow. His title of Yonko was revealed just after the Straw Hat Pirates defeated Moria. Due to his actions and role, he is one of the main antagonists of the Wano Country Arc and one of the central antagonists of the Yonko Saga.

Kaido is a tall man who seems to be of middle age, distinguished by his utterly enormous build, shown to abundantly tower over normal humans. He has an extremely broad, well-muscled torso, wide-set shoulders, and accordingly massive, toned arms. Out of proportion in terms of mass are his legs (at least his lower legs), which appear a little minuscule by comparison to his upper self, far less heavily built than his arms yet about the same length (with his feet being tiny compared to his hands).

Kaido's head, atop his extremely bulky neck, is disproportionally small as well (smaller than his hands), and has a pair of large horns colored light-gray protrude from near the ears, first front- and then upward. He has a veined forehead, a big, hairless brow ridge that is usually lowered in the middle, as well as narrow, upturned, bloodshot eyes below, which are parent to small, amber irises. He has a hook nose, and a large, full-lipped mouth. His face is rather long, as well as moderately furrowed: crow's feet and tear-troughs are present around his eyes, as are short creases in place of eyebrows, and laugh lines due to his near-perennial frown and sneer. His black hair consists of an unruly, mostly swept-back mane, revealing his forehead, forming distinctly flat, rectangular locks of which some fall down the front, framing his face and hiding his ears, or jutting upward. His facial hair is neat, done in a wavy, waist-length Fu Manchu mustache paired with a spiked goatee across his broad chin. To the right of his well-defined abs is a massive, recessed scar, shaped like an X, which reaches up to his right pectoral. A tattoo of dim-reddish segments resembling reptilian scales, outlined in golden color, goes from his left pectoral down the front of his left arm, ending in correspondence to the wrist with a white (dark in the manga), traditionally-shaped skull on the lower forearm.

Clothing-wise, Kaido dons a dark-bluish-purple, feathered overcoat draped on his shoulders, and below a plain, lavender, tight-fitting, open shirt with long sleeves. He has a black bracelet with yellow (dark in the manga) spikes above each of his wrists. Upholding said shirt is a thick, light-gray shimenawa as a rope belt, which has from two of its frontal, central interstices a pair of white shide hanging down. More outwardly from below the rope hang two additional pieces of fabric: rectangular, hemmed flaps that each have, from two hemmed holes at their bottom, a short, thick, golden torus chain attached to themselves. Further, Kaido has two yellow straw-cord waistbands below the shimenawa to secure a short, hanging row of thin, reddish ribbons. Finally, the rest of his lower wear consists of simple, baggy pants of gray-green color, tucked below the knees into simple, blackish boots. 20 years before the current storyline, Kaido had a shorter mustache, no beard and lacked the scar on his chest.

Kaido is a merciless, aggressive, and confident warrior who never misses an opportunity to gain an advantage in war, as evidenced by his plan to attack Whitebeard during the latter's attempt to save Portgas D. Ace from execution. Kaido seems to harbor a general sense of unconcern for most things, including the very nature of the world and the lives of himself and his subordinates. He apparently desires excitement and chaos, as he is prepared to start the largest war in the world because he felt it was too mundane. This recklessness, coupled with his apparent inability to die, has caused Kaido to make attempting suicide as his hobby.

However, Kaido seems unusually invested in his goal of creating a formidable all-Zoan crew, to the point where he attempted to drown his sorrows in alcohol after receiving the news that he could no longer buy Zoan Devil Fruits in large quantities. Kaido also has a great interest in Raftel, having taken a Road Poneglyph under his ownership and also went to the brutal extent of threatening Kozuki Oden for his knowledge and ruthlessly hunting down his son Kozuki Momonosuke and three retainers Kin'emon, Raizo, and Kanjuro.

He is also pitiless and not open to negotiations or excuses, making it unwise to provoke or underestimate him; this is enforced dramatically when Donquixote Doflamingo, a former Shichibukai and former World Noble known for his fearless attitude, was very afraid of angering Kaido when he became potentially unable to fulfill his end of their business deal due to Trafalgar D. Water Law holding Caesar Clown hostage. One of his crewmates later stated that Kaido would be very angry once he heard the news of the SMILE Factory's destruction. This unreasonable attitude caused a group of Kaido's subordinates including X Drake to attempt to deliver the news of Doflamingo's defeat to the Yonko from a distance rather than approaching him in person. Kaido has also shown to be extremely cruel, even towards children. After he murdered Kozuki Oden, he viciously insulted Oden right in front of his son Momonosuke, adding mockery to Momonosuke's sorrow and hopelessness. Adding to this, he brutally attacked Tama, even though she was no threat to him, and left her for dead.

Kaido is highly confident in his power and considers himself to be far above the likes of Supernovas, referring to their actions as "little pirate games", even refusing to take the Straw Hat Pirates and Heart Pirates seriously despite them crippling his SMILE trade; this is reinforced by his belief that defeating a Shichibukai is nothing to be impressed with and his dismissal of Donquixote Doflamingo as being weak. He was also quick to threaten to kill Big Mom when she announced her intention to come to his territory, showing no reservations despite Big Mom possessing power equivalent to his own.

Kaido is a heavy drunkard who loves to drink sake and while drunk, his mood changes erratically, such as when he quickly went from being melancholic over his inability to increase the number of his Gifters and fulfill his dream of having a crew consisting of only Devil Fruit users to becoming angry and violent, brutally beating his subordinates and cursing Luffy and Law. In fact, Kaido is such a habitual drinker that he even dislikes being sober at any given time.

Despite his immense arrogance and confidence in his power, Kaido does acknowledge other individuals of exceptional strength as he sought to recruit powerful individuals into his crew such as Shutenmaru and also Eustass Kid. This extends to enemies who offended him such as Luffy who had caused him to lose his SMILE supply when he intentionally held back when defeating the latter and expressed his intention to recruit Luffy into his crew as he still considered Luffy to be a potentially formidable soldier, and opted to try to break his spirit and recruit him as a subordinate instead of killing him immediately. When Big Mom attempted to enter Wano, Kaido feared of it becoming an all-out war and ordered his crew to stop her and her crew.

Like other people, Kaido has a unique laughing style: "Worororo". A second one of his has been observed as he was drunk: "Fuhihihi".
