Digimon Adventure
One of the Digimon Myotismon brought to the Real World. He was swimming around in Tokyo Bay during August 1 and August 2. But on August 3, MegaSeadramon was given the task of preventing outside interference from the sea. When Joe and T.K. attempted to get into the city, MegaSeadramon attacked them at Rainbow Bridge. When T.K. threatened to drown, Joe realised that only he could save him and his Crest began to glow for the first time. Ikkakumon Digivolved to Zudomon and destroyed MegaSeadramon.

Digimon 02
One of the Digimon under the control of the Dark Spirals, MegaSeadramon trapped the DigiDestined in an offshore oil platform. Cody was able to escape in a submersible and call on Joe for help. As Ikkakumon held MegaSeadramon off, Joe and a Whamon freed the other DigiDestined. Cody then picked up and activated the Digi-Egg of Reliability and Armadillomon digivolved to Submarimon. Submarimon and Ikkakumon then worked together to destroy the Dark Spiral controlling MegaSeadramon. (It seems that the MegaSeardramon shown in this episode was the same Digimon which Joe fought in the first season since Ikkakumon called it "his old foe".) Some time later, the DigiDestined called on Ikkakumon to help them protect the sixth Destiny Stone from BlackWarGreymon. Besides the Dolphmon, Ikkakumon called the very same MegaSeadramon to help out too. Despite the combined effort, however, BlackWarGreymon parted the waters, washing the aquatic Digimon away and destroyed the stone.
