Kaido —

Kaidou is a middle-aged man who cuts an imposing figure due to his extreme height of 710 cm (23’4) and the bulk of his muscles, making him dwarf normal humans. Overly top-heavy in build, he has a well-muscled torso with wide-set shoulders, thick arms,[1] and somewhat out-of-proportion legs; far less heavily built than his arms yet about the same length (with his feet much tinier than his hands). Kaidou's head, atop his bulky neck, is disproportionally small as well (smaller than his hands) and has a massive pair of gray-white, sharp-pointed horns coming out of its sides, curving slightly to the front, then upward. He has a longish face with a heavy, hairless brow ridge topping sharp, often bloodshot eyes (parent to small, yellow irises),[36] plus, a hook nose and a large, full-lipped mouth. Kaidou is near-always seen frowning and is moderately wrinkled: particularly prominent being his crow's feet below his eyes, forehead lines, and laugh lines from always sneering. His black hair consists of an unruly, mostly swept-back mane down to his mid-back, which forms distinctly flat, rectangular locks of which some fall down near the front, over his ears, or jut upward. His facial hair is done in a wavy, waist-length Fu Manchu mustache that pairs with a spiked goatee across his chin. Right of Kaidou's defined abs is his only scar: a massive, recessed X-shape whose upper points reach to his pectoral, Clothing-wise, Kaidou dons a blue purple, feathered, sleeveless overcoat draped on his shoulders, and below a lavender, tight-fitting, open shirt with long sleeves.[39] He has a black bracelet with golden (dark in the manga) spikes above each wrist. Upholding said shirt is a thick, off-white belt of laid rope festooned with a pair of white, hanging shide in the front. More outwardly from below the rope hang two additional pieces of fabric: rectangular, hemmed flaps (which may be the bottom of said shirt) that each have, from two hemmed holes at their bottom, a short, thick, golden torus chain attached to themselves. Two yellow straw cords are below the shimenawa, serving as waistbands to secure a short, hanging row of thin, red ribbons. Finally, the rest of his lower wear consists of simple, baggy pants of gray-green color, tucked below the knees into simple, black boots.

Kaidou is a merciless, aggressive, and confident warrior who never misses an opportunity to gain an advantage in war. He suffers from bouts of apathy and boredom, harboring a general sense of unconcern for most things including the very nature of the world and the lives of himself and his subordinates. He keeps a grumpy disposition with little pleasure and excitement in his life and is constantly frowning most of the time. As such, he craves excitement and chaos, wanting to start the largest war in the world because he felt it was too mundane. This was true even during his childhood as a soldier under the service of the Vodka Kingdom, with a young Kaidou barely showing interest in anything outside of constant warfare. Apparently, Kaidou always had issues with the world he lived in, particularly the people governing it, of which authority he did not respect due to his beliefs that the true worth of someone could only be gauged in the battlefield Kaidou is a heavy drunkard who loves to drink sake, which causes his mood to change erratically when he becomes inebriated. While drunk, Kaidou may become more destructive by accident since he ends up caring little for his surroundings, to the detriment of his own crew and their operations. In fact, Kaidou is such a habitual drinker that he even dislikes being sober at any given time. Kaidou has a unique laughing style: "Worororo" (ウォロロロ, Worororo?). A second one of his has been observed as he was drunk: "Fuhihihi" (フヒヒヒ, Fuhihihi?). Despite his love for battle, Kaidou is pragmatic enough to avoid conflict that could potentially devastate his forces and territories Akin to the reputation of an oni, Kaidou is savage, brutal and believes that might makes right, using his near unrivaled power to govern others through fear and intimidation while making examples of them should they ever decide to not obey or rebel against his rule. Kaidou, interestingly, does not seem to view himself as a human at all, fiercely thinking that his lineage should not hold a friendly relationship with other humans, but rather distrust and oppose them, under the reasoning that the latter are unable to view the former as anything else than monsters. This is likely due to the trauma he experienced as a child, as he was forced to fight as a soldier at a young age, only to be betrayed and sold off by his own country because they feared him. Kaidou is known to be hard to reason with and not usually open for negotiations or excuses, making it unwise to provoke or underestimate him Kaidou venerates strength and military might above all else, with those ideas being the foundation behind his constant amassing of strong subordinates and numerous weapons. He follows the philosophy of "survival of the fittest" and that most problems can be resolved through brute force
