"My name is Yamato! I'm Kaido's son!" Yamato greatly admires the legendary samurai Kouzuki Oden to the point of even proclaiming to carry his identity. Yamato has self-identified as Oden on multiple occasions and has even emulated his gender, proclaiming to be the son of Kaidou due to Oden being a man. Although initially carrying doubts as to how to present as Oden, Yamato has steadily expressed a straightforward attitude regarding this identity as time has gone on, even proclaiming this as such to Oden's son Momonosuke, to the boy's horror. Although having wholeheartedly embraced this identity, Yamato retains his original persona, referring to Yamato as his "other name".yamato does not seem to like being misnamed, having quickly corrected Luffy when given a nickname. Having read of the great exploits documented by Oden in his logbook, which he considers his "bible",yamato dreams of leaving Wano Country's confines and setting out to sea with the Straw Hat Pirates, much like Oden did with the Whitebeard and Roger Pirates decades before.Yamato also wishes to fulfill the goals that Oden had, namely opening Wano's borders, in direct defiance to Kaidou's wishes for the country.Yamato has shown to be extremely strong-willed, having put up considerable resistance to Kaidou's imprisonment despite taking decades to finally break free. Although initially seeming to be more subordinate to him previously, Yamato's battle with Ace led to him destroying Kaidou's dragon statue in an act of defiance that has since led to more outright rebellion.Yamato has engaged in combat with Kaidou numerous times and has openly expressed opposition and defiance to his plans concerning the two of them, accompanied by insults.When the Ninja-Pirate-Mink-Samurai Alliance invaded Onigashima, Yamato was immediately willing to help them and had no qualms with attacking members of his father's crew, making his intentions and loyalty clear to them in the process.Yamato is also willing to go to great lengths to achieve his objectives, having basically kidnapped Luffy in order to get to talk to him and following through with this tactic even after Luffy responded by fighting back.Yamato is more than willing to put his body and life on the line to protect people out of care, believing that Oden would never abandon a comrade in danger. Yamato resolutely withstood a barrage of powerful artillery strikes by the Armored Division to protect Momonosuke,and later confronted Kaidou alone to stall him until Luffy returned despite knowing he was no match for his father. However, Yamato also takes enjoyment in engaging in combat; despite framing his plan to split up from Momonosuke as a decoy strategy to trick the Beasts Pirates, Momonosuke and Shinobu both noted to themselves that he seemed mainly interested in going to fight.
