Seadramon

Seadramon
Seadramon is an Aquatic Digimon, digivolved form of Betamon. An Aquatic type Digimon that has a long body like a large snake. With his long body, he is able to attack forthcoming enemies by coiling around it and tightening it until the enemy ceases to breathe. He swims about the Net Ocean and Dragon Eye Lake, but he has no intelligence, only the instincts to survive play an important role here.

Digimon Adventure
During their first night in the Digital World, the DigiDestined come across an abandoned trolley car on the shores of Dragon's Eye Lake, where they decide to spend the night. However, Taichi "Tai" Kamiya and Agumon accidentally strike a large, red, leaf-like object with an ember from the fire, and it turns out to be the tail of a very angry Seadramon, who retaliates by dragging the chunk of shore with the trolley car on it to the middle of the lake. Yamato "Matt" Ishida is the only one not on that part of the shore and leaps into the water to save the others. Seadramon notices him and grabs him with his coils. To save him, Gabumon digivolves to Garurumon for the first time and battles Seadramon, seeing him off. It is implied by its Digimon Analyzer profile that the MegaSeadramon in Myotismon's army is this same Seadramon.

A Seadramon appears in the Real World during the Dark Masters reign. It disappears back to the Digital World upon Apocalymon's defeat.

Digimon Adventure 02
Seadramon is the digivolved form of Betamon, the partner of Michael Washington, an American DigiDestined. He digivolves the first time when the group, who is in Digitamamon's restaurant, is attacked by a Dark Spiral controlled Gorillamon. Seadramon then attacks Gorillamon and drags him underwater, until Togemon destroys the Spiral. Michael and his Seadramon show up again later when Digimon begin to appear in the Real World around Christmas time and battle a Cherrymon at Rockefeller Center with help from ExVeemon, Lillymon and the other American DigiDestined's Digimon.

Digimon Battle Pets
In the Bandai release of the Digimon Battle Pets in 1997, Seadramon is one of the digivolved forms of Betamon. To get Seadramon, the person must raise their Betamon medium-poorly and wake it up during the night 0-9 times. Seadramon is one of the weakest Champion level Digimon obtainable. If treated perfectly, with a win streak over 50% (with 15+ battles), Seadramon can digivolve into the ultimate level Mamemon.

Seadramon digivolves from Betamon, then it digivolves into MegaSeadramon or Megadramon.

Seadramon is also found at Dragon Eye Lake (near the three Goburimon). In the morning, Hiro sees a big black shape in the lake, going back and forth. It eats anything. When Hiro catches Seadramon, he can ride across to Beetle Land. If he catches it a second time, he can tell it to give him a special item or a digivolution item.
