Chuumon is an Animal Digimon. A rat-like Digimon that is always feeding Sukamon with unscrupulous thoughts. It has forged a strong friendship with Sukamon (that said, it might be only Chuumon that thinks this?), after a past incident where Chuumon was caught in a Carnivore system trap placed on the Network, and was saved by Sukamon who just happened to be passing by. While it is generally cowardly, its cunning is unparalleled and it will dash away to safety at the first sign of danger.
