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 who had been there since before the battle on the internet ensued. All the Kuramon soon gathered at Tokyo Bay near the Rainbow Bridge and merged, forming Armageddemon. He easily defeated Omnimon and Imperialdramon Fighter Mode. Then 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.
