Armageddemon

Armageddemon is a unique Digimon that was the result of unbelievably large amount of Kuramon coming together, fusing and mutating.

Revenge of Diaboromon
After Omnimon defeated Diaboromon for the 2nd time, Diaboromon split into many Kuramon and appeared in the Real World to rejoin the other Kuramon there. All the Kuramon soon gathered at Tokyo Bay mear the Rainbow Bridge and merged to form Armageddemon. He caused some difficulty for Omnimon and Imperialdramon Fighter Mode before Imperialdramon was energized by the Omni Sword to become Imperialdramon Paladin Mode. He then defeated Armageddemon, reverting him to a lot of Kuramon and sending them back to the Digital World.
