First Season (Digimon Adventure)
The first DarkTyrannomon the kids encountered was 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 & his friends had a close run-in with him, but escaped unharmed. DarkTyrannomon reared his head again when the captive populous of Odaiba attempted to escape from the convention centre. Togemon battled him, but was outmatched, when Mr. Tachikawa crashed a van into him, but didn't do any damage. DarkTyrannomon was all set to finish off Mimi's parents, when Mimi's Crest began to glow, allowing Togemon to Digivolve to Lillymon. Lillymon used a flower chain to tame the savage beast, rendering him harmless. Then, Myotismon showed up and blasted DarkTyrannomon into oblivion (although the dub would have it that he was merely sent back to the digital world).

Second Season (Digimon 02)
The Digimon Emperor commonly used the DarkTyrannomon as his muscle. He sicked them on Skull Greymon, on the DigiDestined's Digimon while the Emperor attached the prototype Dark Spiral to Agumon & guard his base. A DarkTyrannomon was among the Digimon that crashed Yamato Ishida's concert and another one was seen in New York being herded to Central Park.

Digimon Tamers
A Dark Tyrannomon appeared in the first episode, fighting a Maildramon & digivolving into Metal Tyrannomon. Another one was seen among the many Digimon through the rip in the sky during Vikararamon's rampage.
