Digimon Tamers: Brave Tamer
After Ryo Akiyama was thrown to space and time by Moon=Millenniummon, he met Monodramon in the ancient Digital World. Monodramon was then chosen to be Ryo's partner by ENIAC. They then went on a series of adventures through time and dimensions together to defeat ZeedMillenniummon, but had to travel to ZeedMilleniumon's place to defeat him. It was there that Millenniummon revealed that he was always Ryo's true partner. In the end Monodramon was able to force a DNA Digivolution between himself and Millenniummon, resulting in a Digiegg which would eventually become Cyberdramon.

By leveling up Monodramon, Ryo could make Monodramon digivolve to Cyberdramon.
