MetalKoromon is a Machine Digimon whose Japanese name is derived from the onomatopoeia for darting about (ちょろちょろ Chorochoro?), whose English name is derived from "Metal Koromon", and whose design is derived from a computer mouse. It is super-tiny and has red eyes that act as photosensors. The appearance of it moving around restlessly seems very cute, but because it is carrying nothing but a simple program that moves in reaction to bright lights, if its surroundings go dark it becomes completely unable to move. The reason why is not understood, but when it is in a good mood, it discharges electricity from the tip of its tail.
A MetalKoromon appears as a possessed driver of the Behemoth, a sentient motorcycle who was terrorizing the Digital World.
