DarkTyrannomon

DarkTyrannomon is a Dinosaur Digimon whose name and design are derived from "Dark Tyrannomon". Although it was originally a Tyrannomon-species Digimon, it was infected by a vicious computer virus, causing a bug in its flesh's configuration data and transforming it into a frenzied Digimon. Its body turned black, its arms grew stronger than Tyrannomon's, and its offensive power grew. It identifies anything reflected in its eyes as an enemy and starts attacking, becoming completely frenzied.

Digimon Adventure
DarkTyrannomon is one of Myotismon's minions. He first appeared in August when Myotismon isolated Odaiba from the rest of Tokyo in his search for the Eighth Child. Mr. Ishida and his friends had a close run-in with him but escaped unharmed. DarkTyrannomon reared his head again when the captive populace of Odaiba attempted to escape from the convention center. Togemon battled him but was outmatched when Mr. Tachikawa crashed a van into him but didn't do any damage. DarkTyrannomon is just about to finish off Mimi Tachikawa's parents when Mimi's Crest begins to glow, allowing Togemon to digivolve to Lillymon. Lillymon used a flower chain to tame the savage beast, rendering him harmless. Myotismon appears at that point and casts DarkTyrannomon back to the Digital World. In the original Japanese, Myotismon instead obliterated the dinosaur.

Digimon Adventure 02
The Digimon Emperor commonly used DarkTyrannomon as his muscle. They first appeared when he sicced them on SkullGreymon, whom defeated them easily, and then on the DigiDestined's Digimon while the Emperor attached the prototype Dark Spiral to Agumon and made them guard his base.
