Centarumon

Centarumon is an Animal Digimon (Beast Man Digimon in Japan) that resembles a centaur with exhaust pipes in his human back and wearing a helmet that shows his one eye.

Digimon Adventure
The first Centarumon seen was the guardian of a temple which was built in honour to the DigiDestined. However it was also a victim of Devimon's Black Gear which was then destroyed by Kabuterimon and Togemon. He then revealed to Koushiro "Izzy" Izumi and Mimi Tachikawa the history of the Digivices but before he could tell them more they were attacked by Leomon (who was under Devimon's control at the time). Centarumon fought against him but was no match for the strong warrior until the light of the Digivices drove the possessed Leomon away. Later it was Centarumon who discovered the Wall of Fire and he informed Gennai but then Apocalymon attacked. After the evil Digimon was defeated, Centarumon returned alongside Gennai.

Digimon Adventure 02
A Centarumon was a partner to an American DigiDestined named Maria and helped the DigiDestined in New York to defeat a Cherrymon. The same one appeared during the final battle against MaloMyotismon.

Saggitarimon returned with a bunch of Centarumon in order to get the Legendary Warriors' possessions (he kept mixing it up with obsessions). After Saggitarimon was sent flying by Angemon, the Centarumon fled.
