Kaido

Kaidou of the Beasts,[8][18][14][10] renowned as the world's "Strongest Creature",[19][11] is the Governor-General of the Beasts Pirates[6][14] and was formerly one of the Four Emperors that ruled over the New World.[5] He is also the father of Yamato.[20][21][22]

Once a promising child soldier at the service of the Vodka Kingdom decades ago, Kaidou was drafted against his will by the Marines but managed to escape and start a career in piracy. He was invited by Edward Newgate to join the legendary Rocks Pirates as an apprentice,[4] where he met and befriended Charlotte Linlin. During the God Valley Incident when the Rocks Pirates met their downfall, Linlin provided Kaidou with the rare Mythical Zoan-type Devil Fruit, the Uo Uo no Mi, Model: Seiryu. He then went on to form his own crew and build it up into a powerful military force determined to challenge the World Government.

After being invited to Wano Country by Kurozumi Higurashi, Kaidou joined forces with Wano Country's shogun, Kurozumi Orochi,[23][24] and occupied Onigashima as his base.[9] After a failed attempt from Kozuki Oden and the Nine Red Scabbards to overthrow him, he continued to accrue military might in Wano Country for 20 years before deciding to dispose of Orochi and proceed with his plan for the New Onigashima Project.[Kaidou is a middle-aged man who cuts an imposing figure due to his extreme height of 710 cm[8] 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).[33][34] 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 upwardRight of Kaidou's defined abs is his only scar: a massive, recessed X-shape whose upper points reach to his pectoral,[1] given to him by Kozuki Oden.[37] Twenty years later, Roronoa Zoro managed to add another scar to Kaidou's chest that runs from the top left point of the first scar to near his left shoulder.[38] A tattoo of dull-red segments resembling reptilian scales, individually bordered in orange, goes from Kaidou's 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.[1]

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.[1] After his battle against the Big Mom, Kaidou is seen wearing a white version of his usual shirt, which exposed the middle of his body.Kaidou is a merciless, aggressive, and confident warrior who never misses an opportunity to gain an advantage in war.[42] 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.[43] 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.[44]

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.[45] In the past, Kaidou once believed that only he could change the world, supposedly in an attempt to mimic Joy Boy and his legend; however, Kaidou has admitted that his methods and overall goal ended up being far different.[46][47] Still, Kaidou remains curious about Joy Boy and whether anyone else is capable of taking up their mantle.[48] He also thinks that Joy Boy could be the one person capable of ever taking him down.
