First season (Digimon Adventure)
Digitamamon was first seen running a restaurant with Veggiemon who made Joe and Matt work off their bills (Matt worked there to prevent Joe from causing more accidents that would expand their labor and DemiDevimon paid Digitamamon to keep him there). Tai, Agumon, T.K. and Patamon found them. When trying to escape, Digitamamon grew large and attacked. When Garurumon and Ikkakumon weren't enough, Matt's thought of friendship allowed Garurumon to Digivolve to WereGarurumon and defeat him.

Second Season (Digimon 02)
Digitamamon ran a restaurant near the lake and the bill caused trouble for Yolei until Mimi and Palmon appeared with Michael and Betamon. T.K. realized this was the same Digitamamon that had Joe and Matt work in his restaurant. When a Gorillamon under the control of the Dark Spiral attacked, Digitamamon threw himself in front of the DigiDestined and was sent flying. After Gorillamon was freed, Digitamamon rolled back. But this time, he had a unseen Dark Spiral in his shell. When Halsemon, Flamedramon and Digmon's attacks couldn't get though his shell, Mimi tried to convince Digitamamon that he wasn't evil and Digitamamon tackled her. That made Yolei mad and her talks of her trying to be sincere activated the Digi-Egg of Sincerity. Halsemon De-Digivolved to Hawkmon and became Shurimon. Shurimon used the shuriken on his back to keep Digitamamon's shell open as Pegasmon and Nefertimon trapped him. Shurimon used his Double Star attack and destroyed the Dark Spiral. Another Digitamamon (Or was it the same one?) ran a Chinese restaurant with Tapirmon. They got their soup ingredient from a pool of it which contained a Destiny Stone. After Azulongmon appeared and BlackWarGreymon left, he was nearby when Azulongmon told the DigiDestined about the Digital World's past. After that, he and Tapirmon gave the DigiDestined a free dinner. Later on, a Digitamamon appeared during the final battle against MaloMyotismon.

Digimon Frontier
Some Digitamamon were seen at the Fortune Teller Village (where 3 were smaller than usual) and the Autumn Leaf Fair (during both visits).
