First Season (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 & Agumon accidently struck a large, red, leaf-like object with ember from the fire - & it turned out to be the tail of a VERY mad Seadramon, who retaliateds 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 & 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.

Second Season (Digimon 02)
Betamon Digivolved to Seadramon when Digitamamon's diner was attacked by a Dark-Spiraled Gorillamon, with Togemon helping to remove the Spiral. 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 & the other American DigiDestined's Digimon.
