Chrysalimon

Chrysalimon is the Champion stage of the Diaboromon line. But curiously, Chrysalimon is the only member of the line to never appear in the movies, because Keramon skipped the Champion stage and digivolved straight to it's Ultimate form, Infermon. Its name is derived from chrysalis. It is also known as Kurisarimon (a romanization of Chrysalimon's name in Japanese symbols).

Chrysalimon possesses a hard-armored body. The tentacles on its back can destroy another's data.

Digimon Tamers
While riding throughout the Digital World on the Behemoth Motorcycle, Beelzemon stumbled upon a group of Chrysalimon. He destroyed some of them until Calumon's power Digivolved the remaining Chrysalimon to an Infermon but Beelzemon destroyed it anyway. Later on, a bunch of Chrysalimon attacked Beelzemon (who at this time was waving after what has happened between him and the Tamers), De-Digivolving him to Impmon. The same bunch was affected by Calumon's power and Digivolved to three Diaboromon to help fight against D-Reaper.
