Yamato is the rebellious son of Kaidou of the Four Emperors.
SpoilerYamato presents himself after the legendary samurai Kouzuki Oden.
This profound admiration for the legendary samurai has led to the decision to embody everything related to the samurai to the extent of proclaiming to be a man as well, and hence Yamato is widely referred to as Kaidou's son.SpoilerAt the age of eight, Yamato was present at Oden's execution during the Legendary Hour twenty years before the events of the story, and was mortified by the sight. After the execution, Yamato rushed to Oden's Castle to save Momonosuke, but could only watch as Kaido threatened the boy. Although angered and saddened by Oden's death at the hands of Kaido and Orochi, Yamato felt a burning passion rise, and after discovering Oden's logbook in Kuri, Yamato realized that someone needed to carry on Oden's will, and so began to emulate everything about Oden himself as to carry on his legacy. At some point in the latter's childhood, Kaido learned about Yamato's desire to emulate Oden and responded by beating Yamato up. He would also put explosive shackles on Yamato to prevent any chance of escape from Onigashima.SpoilerYamato met the pirate, Ace a few years ago and was initially antagonistic towards him due to his excessive rampage on Onigashima. The two quickly became friends, however, after Ace recognized that Yamato was being held captive by Kaido. As they drank sake together, they talked about the current generation of pirates and Ace's little brother, Luffy. Yamato would have liked to sail out of Wano with the Spade Pirates, but was kept prisoner on Onigashima, shackled with explosive handcuffs. However, Yamato created a Vivre Card for Ace so they could meet again. Yamato thought highly of Ace and believed he would be the one leading the new generation of pirates, until his untimely death at Marineford two years ago.
