MetalPiranimon is an Aquatic Digimon and a carrier of the X Antibody whose name and design are derived from "Metal" and the Red-bellied Piranha (Pygocentrus nattereri). A swarm of these dangerous Digimon were discovered within the Net Rivers of a particular region, and though it is said that the number of Digimon that have become Megas is extremely small, there are schools of these Digimon which will bite into any Digimon who passes into their territory, killing it immediately. There are razor-sharp teeth in its "Metal Head" cranium, and because its tenacious jaw functions like a vise, it bites and completely rends every armor. However, because the feature named "Metal Head" 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".
Digimon Pendulum X 3.0Edit
MetalPiranimon can digivolve from any Ultimate Digimon if it has suffered three or less care mistakes, and been feed three Metal Rise, three CHO-Energy, and at least one D-Poison. To digivolve from Grademon, it must be in its second generation. It can also Blast Digivolve from Omekamon, and to Dynasmon X or Alphamon Ouryuken.
MetalPiranimon appears in the second Northwest area of Dark Castle and can be unlocked by winning the "Poop" mini-game.
