Seadramon is a Sea Animal Digimon. It has a long, serpentine body, which it uses to wreathe itself around enemies that are coming to attack, and constrict until the enemy suffocates. Naturally, it doesn't have intelligence or speech, and it swims around the Net Ocean leisurely according to its instincts.[5]


  • Ice Blast[citation needed] (Ice Arrow): Spews absolute zero breath from its mouth, instantly freezing water that it fires at the opponent.
  • Water Shock (Water Breath)[please confirm]: Shoots a blast of water from its mouth.
  • Shimetsusukeru (しめつける Shimetsukeru?, lit. "Bind"): Wraps around the opponent and squeezes it.


Seadramon is based on sea serpent.
