Koh


 * Koh (コウ) is a rising Tamer in the Light Fang organization, and is Sayo's main rival; by the end of her story, he has attained the rank of Platinum Tamer. His design is the male version of the protagonist from Dawn. He is partnered with Coronamon (who digivolves to Firamon, then Apollomon), RizeGreymon (who digivolves to ShineGreymon, then ShineGreymon Burst Mode), and Angemon (who digivolves to Seraphimon), and his NaviDigimon is Gatomon. Koh's name is likely derived from "kou" (光).
