Death-X-DORUguremon

An Undead Digimon of the Prototype Digimon "DORU Series" that was experimented on in search of further evolutions, and was said to, at the time of the experiment, resemble its final form. By continuously preying on the Digicores of other Digimon, it is active despite its deceased condition, and hungers for a vast amount of Digicores in order to evolve. Since it instinctively sniffs out Digicores, the eye and snout portions of its head are covered in armor, and the sharp tips of the blades on its tail and wings are used to skewer many Digimon, allowing it to prey on their Digicores afterwards. Its Special Moves are breaking open the enemy's armor with the horn on its head and engulfing their Digicore (Bloody Cave), and "Metal Meteor".

さらなる進化を求めて実験されたデジモンの原型『プロトタイプデジモン』“ドルシリーズ” の、実験当時の最終形態に酷似しているというアンデッド型デジモン。他のデジモンのデジコア（電脳核）を捕食し続けることで、死んだ状態でありながら活動し、進化するために膨大なデジコアを欲している。本能的にデジコアを嗅ぎ付けるため、頭部の目や鼻は装甲で覆われ、尾や翼にある鋭い剣先は、多くのデジモンを串刺しにして置き、後からデジコアを捕食するために使う。必殺技は頭部の角で敵の装甲を抉じ開けデジコアを喰らう『ブラッディーケイブ（洞窟の意）』と『メタルメテオ』。
