Cyberdramon

Cyberdramon is an Ultimate-level Digimon, partnered with Ryo Akiyama. It's possible that he was the first Digimon to be partnered with a Tamer in this world, since he and his partner both have had experience in another world entirely, the world of the Digi-destined. After their adventure with Milleniummon, where Ryo and Cyberdramon's Rookie form - Monodramon, initated a forced DNA digivolution with Millenniummon to create Cyberdramon, they came to this world. Ryo and Cyberdramon spent most of their time wandering the Digital World until they met the other Tamers there. Cyberdramon is the only Digimon belonging to a Tamer that spends most of his time in his Ultimate form. His Mega form is Justimon.

Cyberdramon is a complete beserker. He likes nothing better than getting his claws into an enemy Digimon and destroying it. It isn't known whether this is an influence of Millenniummon, or whether Cyberdramon is just like that. He is extremely sensitive to evil Digimon, allowing him to register presences that the others miss for one reason or another. However, occasionally he'll go on out-of-control rampages when he starts fighting and the only way Ryo can control him is to use a green energy whip in his D-Arc. However, despite all appearances, Cyberdramon is very observant and does look out for the safety of the rest of the group.
