A Mega Seadramon was a servant of Vamdemon. When Kido Jo, Takaishi Takeru and Patamon tried to enter Odaiba through Vamdemon's fog barrier, they were attacked by Mega Seadramon. Jo's Gomamon evolved to Ikkakumon, but Mega Seadramon attacked them and defeated Ikkakumon. Takeru was in danger of drowning as he fell off Ikkakumon's back. Jo saved him and soon his Crest of Sincerity glowed, allowing Gomamon to evolve to Zudomon. In his Perfect form, it was finally able to defeat Mega Seadramon, allowing them to enter Odaiba.

In "Submarimon's Escape from the Bottom of the Sea", the same Mega Seadramon is controlled by an Evil Spiral. It attacks and traps the Chosen Children inside of an underwater oil platform and waits for their oxygen to run out. They sneak Hida Iori out in a one-man escape pod. He returns with Kido Jo, his Ikkakumon and a Whamon. Ikkakumon fights with Mega Seadramon, but Mega Seadramon has the upper hand. However, when Iori accesses the Digimental of Sincerity that had been hidden in the platform, he armor evolves his Armadimon to Submarimon. Working together, Ikkakumon and Submarimon destroyed the Evil Spiral, freeing Mega Seadramon.

In "Assault on Black War Greymon" the same Mega Seadramon helps the Chosen Children by recruiting several Rukamon and helping them defend a Holy Stone from Black War Greymon in the ocean. Despite their effort, the stone is still destroyed.

While Yagami Taichi, Ishida Yamato, Leomon, and their Digimon partners were battling Waru Seadramon, it called for help, and summoned a Mega Seadramon to aid it. The other Chosen Children then arrived with their partners, and both Waru Seadramon and Mega Seadramon were destroyed by Garudamon.
