Monodramon

Monodramon is a Small Dragon Digimon. Although he has wings, he cannot fly. In the Digital World, Monodramons shrink from fights and battles, but even so one Monodramon has been spotted arguing with an Ogremon over mistimed Body Blow attack. In addition, some call the horn that grows on the tip of his head his greatest weakness, although the truth is unknown.

Digimon Adventure V-Tamer 01
Ryo and Monodramon end up in the V-Tamer world, where they team up with Tai and Zeromaru against Vikemon, defeating him despite Tai and Ryo's bickering.

Digimon Tamers: Brave Tamer
After Ryo was thrown to space and time by MoonMillenniummon, 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 (Millenniummon) 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.
