Digimon Adventure 02
Armadillomon first digivolved to Ankylomon to protect Cody from Thundermon, who the DigiDestined encountered when they were helping to rebuild the Digital World after all the damage done by the Digimon Emperor. Since then, Ankylomon has appeared more than Digmon and Submarimon. Later, during the DigiDestined's final battle against BlackWarGreymon, Ankylomon was able to DNA digivolve with Angemon to Shakkoumon, who was the first to actually inflict any real damage on the Mega-leveled BlackWarGreymon. He was also vital to battle against the Daemon Corps and MaloMyotismon.
