Betsumon

Betsumon (ベツモン) is a unique Puppet Digimon in the Digimon franchise, known for its ability to mimic other Digimon to confuse enemies. While similar to Etemon and Monzaemon as Puppet Digimon, Betsumon stands out with its capacity to disguise itself as various Digimon by changing its Digimon Suit. It is often seen wearing a Gatomon costume, though it is relatively weak. The ring on its tail is not a Holy Ring but a replica, resembling a Black Ring. Betsumon can also impersonate humans. It appears in anime series like "Digimon Xros Wars: The Young Hunters Who Leapt Through Time" and "Digimon Ghost Game," where it disguised itself as Gammamon to manipulate humans. Betsumon's attacks include "Cold Gag" and "Tsukkomi Punch", and it can copy other Digimon's moves, such as Omnimon's "Grey Sword," Shoutmon's "Rock Damashi," and Astamon's "Hellfire." Its name derives from a Gatomon cosplayer and its behavior reflects its mimicry. It’s an eccentric Digimon that enjoys confusing foes.
