Ryo's Digimon

A Digimon who has a human partner is normally most of the time in his Rookie level. But Ryo's Digimon Cyberdramon is the Ultimate form of the Rookie Monodramon. If we know something about Ryo's mysterious appearance we also know that Cyberdramon is a special Digimon. Ryo's biggest opponent in WonderSwan games was Milleniummmon (more about it in Ryo's Appearance) and Milleniummon's strongest form was ZeedMilleniummon. In the end of the last game Monodramon (Rookie) and Milleniummon had a fusion to Cyberdramon. Because of this evil vs good thing CyberDramon is so agressive, while Monodramon's not!
