Grimmon

Grimmon
Grimmon is an unobtainable boss Digimon appears in the games Digimon World Dawn and Digimon World Dusk.

Digimon World Dawn/Dusk
Grimmon first appeared as a hooded figure in the Thriller Ruins, spotted by Night Crow as they investigated an outbreak of violence in local Digimon. The figure later appeared after the Normal Tamer Tournament, and was chased back to CITY, where it was revealed as an egg-shaped purple "Mystic Energy" who attacked CITY and caused all of the Digimon to revert to their In-Training level, except for the player's Digimon and NavDigimon, the Team Leader, and Bokomon and Neemon (who even comment how odd it is that they didn't degenerate). The player defeats the Mystic Energy inside of their respective headquarters, which then flees. The "Mystic Energy" is encountered again in Limit Valley, where it displays the power to control Digimon (Seasarmon and SandYanmamon in particular), which it uses to attack the protagonist before finally revealing itself as Grimmon.

After being defeated once more, Grimmon shows up at Access Glacier, where it has the protagonist's Chief, the Chief's partner, and his/her friends under its control (Chief Glare and Ophanimon in Dawn and Chief Julia and ChaosGallantmon in Dusk), using his ChronoDSR ability. When the technique fails to work on the protagonist, it sends the Chief's partner at him/her before fleeing.

It appears once last time in Chaos Brain, where the Chrono Core fuses with it to become ChaosGrimmon.
