MetalGreymon (Vaccine) is a Cyborg Digimon whose name and design are derived from "Metal Greymon". It has mechanized more than half of its body, incorporating technology appropriated from Andromon. The MetalGreymon of Folder Continent are Cyborg Digimon that succeed in perfectly digivolving from Greymon, and draw out a stronger power which cannot be compared with those of File Island. In order to digivolve to MetalGreymon, it must fight its way through and defeat the formidable opponents who come against it. 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.
