Variations Subspecies


Digimon Dictionary


A species of Seadramon that survived the harsh environment around the Folder Continent, morphologically evolving in an attempt to survive the Digital World's harsh survival-of-the-fittest regime. Its body has grown larger, and while the hardness of the outer covering of its head has also increased, a lightning bolt-shaped blade has grown from the top of it. It has a more well-developed intellect than those sported by other Seadramon species, and it will persistently track down and chase after the enemy like a torpedo before reliably slaying it. Its special attack is "Thunder Javelin", which is emanated from the powerful lightning blade on its crown. A powerful generator has been attached underneath the hard shell on its head just so that it can perform this special attack. (Wildermon)

かこくな かんきょうを 生きのびるために
シードラモンが 進化した 水せいがたデジモン
あたまには イナズマがたの ブレードが 生え
がいかくも かたさをまして 体もおおきくなった
てきを みつけると ぎょらいのように ついびして
かくじつに しとめる


Digimon V-Tamer Residence


Seadramon usually evolves into this species that has a slightly more burlier form. It's often seen mainly within the severe environments around the continent of Folder. The hardness of the outer shell that covers its head has increased, serving a purpose much like that of an insect's shell wherein it increases its defensive power, and the lightning-shaped blade that grew on its calvarial can generate and fire electric shocks via the equipment stored within. Both its intelligence and swimming speed have also developed and it chases and kills its opponents vengefully. (Wildermon)
