Millenniummon

Millenniummon is a Composition Digimon. 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.

Attacks
 * Time Unlimited: Creates a pocket dimension with compressed time, and traps an opponent there for an eternity.
 * Dimension Destroyer: Destroys the pocket dimension it created.
 * ∞ Cannon: Fires superdreadnought-class energy waves from its two cannons.
 * Ultimate Fusion

Design
Millenniummon is the combination of Kimeramon and Machinedramon. Millenniummon retains most Kimeramon's chimeric Digimon parts, albeit with a darker color scheme. Its wings and tail are replaced by Machinedramon's aura, which visibly retains its Psycho Blasters.
