Devidramon

Devidramon is an Evil Dragon Digimon with four blood-red eyes. It is usually ridden by Digimon such as Myotismon and it has been said to have been created as a result of hackers misusing the network.

Digimon Adventure
A Devidramon was first seen pulling Myotismon's stagecoach. A number of them were summoned by Gatomon to prevent the DigiDestined from pursuing Myotismon. Some were destroyed by Garurumon, Kabuterimon and MetalGreymon. The 2nd time into Myotismon's castle, MegaKabuterimon took the remaining two out so that the DigiDestined could get to the door to the Real World. However they were never intended to defeat the DigiDestined, only to delay them sufficiently.

The Digimon Emperor rode a Devidramon before and after the creation of Kimeramon. Wormmon tackled the Digimon Emperor and rode the Devidramon on a collision course upon Kimeramon and both were attacked.

Another Devidramon larger than normal was seen in New York when Digimon started to appear in the Real World.
