Yamato greatly admires the legendary samurai Kozuki 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 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.
