GranLocomon is a Machine Digimon whose name and design are derived from "Grand Locomon". It is a Vehicle-species Digimon that digivolved from Locomon. It broke through the limits on the speeds sought by Locomon, and so it rushes about within the Network at super-speeds. It has an extremely strong competitive spirit and the personality of reckless types, and since its power is also incomparable, those who suffer its assault are smashed to smithereens. Although Locomon was not able to run when there wasn’t any rails, when GranLocomon is in a place where there aren't any rails, it is able to just produce rails to run on itself.
