Digimon 02
We first saw Armadillomon Armor Digivolve to Digmon on the day of his revival, when the Digimon Emperor abducted Davis. Cody's desire to understand life's mysteries evoked the power of the Digi-Egg, allowing Armadillomon to Armor Digivolve to Digmon and destroy the Dark Ring on Drimogemon. After this, Digmon became a valuable fighter during the Digimon Emperor's reign of terror. But when Ken renounced his evil persona, Digmon was no longer needed and so appeared only a few times; Ankylomon was used instead. But during the battle with MaloMyotismon, Digmon was manifested as a result of Cody's dream for justice.

Hurricane Touchdown/Supreme Evolution! The Golden Digi-Eggs
Armadillomon became Digmon to help Flamedramon, Gargomon, and Halsemon to fight Kokomon in the form of Antylamon. When Antylamon emerged as Cherubimon, the four Digimon were defeated.

Digimon Frontier
Some Digmon were seen at the Autumn Leaf Fair and the Great Trailmon Race.
