He first appears in Book Three as Reppamon. He has been told by Rey to follow the group of Digidestined and tamers while they combat the Demon Lords. Eventually, he dedigivolves into Kudamon and learns he is the partner to Kristy Nonaka, who is Rika's younger sister from another reality.
He also turns out to be either the future or past version of Kentaurosmon of the Royal Knights. In Book Four, Kudamon accidentally combines with his alter-ego and goes out of control in his mega form. Kristy manages to stop the rampage by Biomerging with her partner, the only time they have combined so far. In Book Seven, he and Kristy helps to babysit the young Rejimon, daughter of Renamon and Guilmon. His champion form, combined with a modify card to enlarge his size, helped to evacuate during the emergency caused by Rayleigh's accusation of the tamers being behind the Prime Minister's murder.
