Millenniummon

Millenniummon appeared in the 1999 video game called Digimon Adventure: Anode Tamers and Cathode Tamers. Millenniummon is a Composition Digimon whose name is derived from "Millennium". It fused the overwhelming power possessed by Machinedramon and the data of various powerful Digimon possessed by Kimeramon. It is said to be impossible to defeat, and at present the unclear cause of its fusion is being ascertained, but it is unlikely that any clues will be found.
