First season (Digimon Adventure)
Digitamamon was first seen as a restauranteur who ran a restaurant with Veggiemon who made Jou Kido and Yamato Ishida work off their bills (Yamato worked their to prevent Jou from causing more accidents that will expand their labor and DemiDevimon paid Digitamamon to keep him there). Taichi Yagami, Agumon, Takeru Takaishi, and Patamon found them. When trying to escape, Digitamamon grew large and attacked. When Garurumon and Ikkakumon weren't enough, Yamato's thought of friendship allowed Garurumon to Digivolve into WereGarurumon and defeated him.

Second Season (Digimon 02)
Digitamamon ran a restaurant near the lake and the bill caused trouble for Miyako Inoue until Mimi Tachikawa and Palmon appeared with Michael and Betamon. Takeru realized this was the same Digitamamon that had Jou and Yamato work in his restaurant. When a Gorillamon under the control of the Dark Spiral attacked, Digitamamon threw himself in front of the Digi-Destined and was sent flying. After Gorillamon was freed, Digitamamon rolled back. But this time, he has a 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 Miyako 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 his 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 ran a Chinese restaurant with Bakumon. They got their soup ingredient from a pool of it which contained a Destiny Stone. After Azulongmon appeared and Black WarGreymon left, he was nearby when Azulongmon told the Digi-Destined about the Digital World's past. After that, he and Bakumon gave the Digi-Destined a free dinner. Later on, a Digitamamon appeared during the final battle against MaloMyotismon.
