The answer
Chapter 965 · updated
Oden's son in One Piece is Kozuki Momonosuke. Kozuki Oden proudly holds up his newborn son aboard the Moby Dick and declares the name after rejecting food-themed suggestions from the crew. ch. 965, p. 4 The infant receives the full name Kozuki Momonosuke amid cheers of "HE'S BORN!" and "HOGYA! HOGYA!". ch. 965, p. 4 Years later Kin'emon explains to Momonosuke that the ruined castle was called Oden Castle because residents loved Oden, prompting Momonosuke to realize "So that was Momo's father!". ch. 920, p. 2 Oden is the son of shogun Kozuki Sukiyaki and left Wano on voyages with Whitebeard and later Roger before returning. ch. 960, p. 7 The sources establish Oden's parentage and his son's birth and naming but contain no other children.
