MetalGreymon is a Cyborg Digimon whose name and design are derived from "Metal Greymon". It has mechanized more than half of its body. The Metal Greymon of Folder Continent are Cyborg Digimon that succeed in perfectly evolving from Greymon, and draw out a stronger power which cannot be compared with those of File Island. In order to evolve to MetalGreymon, it must be successful in defeating the enemies who come against it, one after another. Also, MetalGreymon's offensive power is said to equal that of a single nuclear warhead, and if the likes of a low-level Digimon suffered that blow, it would be annihilated without leaving a trace. Its "Trident Arm" is made from enhanced Chrome Digizoid.
