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.[8]

More than a decade later, Lucemon is not powerful enough in its Rookie form to destroy the World and instead decides to ask the Vademon where they had summoned Millenniummon in the past and then travels there. After finding the location it is ambushed by Crusadermon and Dynasmon of the Royal Knights, though is still able to go back in time (taking the Royal Knights with it) to when Millenniummon was summoned so that it could ambush it and then seal off its will and mind so that it would do its bidding and also planned to force it to digivolve to its "final World destroying form", then would return with it to the future and destroy the World. The Royal Knights state they will not allow that to happen, though when Millenniummon arrives the gate suddenly gets interfered with, with Mastemon having been convinced by Rasielmon to help as well. It then travelled back in time as well to stop Lucemon's plan and was able to interfere with the ritual, causing Millenniummon to instead appear as an illusion. The three of them then continue to fight Lucemon and eventually are joined by the ghosts of AncientGreymon and AncientGarurumon, with Goblimon and Raremon having convinced them to stop Lucemon from destroying the World. The Legendary Warriors see that it is not powerful enough on its own whilst in its Rookie form to destroy the World which is why it needed Millenniummon's power and since Goblimon and Raremon had asked them to stop Lucemon, not kill it, they decide to instead seal away Millenniummon and are able to do so with the help of Mastemon and Rasielmon. The Royal Knights then kill Lucemon. Tales of the Little Goblin and Its Friend
