MetalKoromon is a Machine Digimon. 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.[5]
