Digimon Battle Pets
In the Bandai release of the Digimon Battle Pets in 1997, Seadramon was one of the evolved forms of Betamon. To get Seadramon, the person must have raised their Betamon medium-poorly, and woken it up during the night 0-9 times. Seadramon was the 3rd weakest Champion level digimon you could get (Tied with Tyrannomon). If treated perfectly, with a win streak over 50% (with 15+ battles) Seadramon could evolve into the ultimate level Mamemon.

Digimon Adventure
During their first night in the Digital World, the DigiDestined came across an abandoned trolley car on the shores of Dragon's Eye Lake, where they decided to spend the night. However, Tai and Agumon accidentally struck a large, [red], leaf-like object with ember from the fire - and it turned out to be the tail of a very angry Seadramon, who retaliated by dragging the chunk of shore with the trolley car on it to the middle of the lake. Matt was the only one not on that part of the shore and leapt into the water to save the others. But Seadramon noticed him and grabbed him with his coils. To save him, Gabumon Digivolved to Garurumon for the first time and battled Seadramon, seeing him off. He appears in the Real World during the Dark Masters reign and disappeared back to the Digital World upon Apocalymon's defeat.

The very same Seadramon was the Digivolved form of Betamon, Michael's (an American DigiDestined) Digimon partner. He evolved the first time when the group, who was in Digitamamon's restaurant, was attacked by a Dark-Spiral controlled Gorillamon. Seadramon then attacked Gorillamon and dragged him underwater, until Togemon destroyed the Spiral. Michael of America and his Seadramon showed up again later when Digimon had begun to appear in the Real World around Christmas time and battled a Cherrymon at Rockefeller Center with help from ExVeemon, Lillymon and the other American DigiDestined's Digimon. Michael and Seadramon also appeared in the final battle against MaloMyotismon.
