Metal Piranimon

Within certain parts of the Net Rivers, a swarm of dangerous Virus-species Ultimate Digimon were discovered. Though it is said that the number of Digimon who have become Ultimates is extremely small, there are schools of Metal Piranimon which will get their teeth into any Digimon who passes into their territory, killing it immediately. There are razor-sharp teeth in its "Metal Head", and because its tenacious jaw functions like a vise, it bites and completely rends every armor. However, because the Metal Head feature is extremely heavy, it keeps its balance with the weight attached to its tail fin. Also, if the red button on its calvaria is pressed then it will simply come off, and be replaced with a new Metal Head. Its Special Moves are biting and rending the opponent from every direction (3D Razor), and using the Metal Head at maximum power so that it doesn't release until it bites through (Max-Power Vise).

ネットの河川の一部の地域で、危険なウィルス種の究極体デジモンが大量に発見された。究極体ともなると個体数は極少と言われるが、付近を通ったデジモンに大勢で喰らいつき、瞬く間に死に至らしめてしまう。頭部“メタルヘッド”には切れ味鋭い歯が有り、頑強なアゴは万力のように作用するため、あらゆる装甲をも噛み千切ってしまう。しかし、その特徴とも言える“メタルヘッド”は非常に重いため、尾ビレに重りを付けてバランスを取っているほどである。また、頭頂部の赤いボタンを押すと簡単に外れ、新しい“メタルヘッド”に付け替えることも可能である。必殺技は敵のあらゆる方向から噛み千切る『３Dレイザー』と、噛み切るまで離さない“メタルヘッド”の最大パワー『マックスパワーバイス』。
