Chrysalimon is an Unidentified Digimon whose name and design are derived from the chrysalis. The Rookie Keramon will go into a chrysalis-like state in order to digivolve into a stronger Digimon, and once it does so it conserves its energy. For that reason, it is completely unable to move, but it is protected by its tough shell, and can attack the opponent with the tentacles extending from its back. In some cases, it can digivolve to Ultimate without becoming a Champion, but it is able to digivolve to a stronger Ultimate by digivolving to Chrysalimon.
