ElDradimon

ElDradimon is a Mutant Digimon. It once wandered into the research data for ancient ruins on a neglected computer, and over a long period time it unified with that data. If it retracts its head, arms, and legs, it looks like nothing more than the ruins of an ancient fortress. Due to the enormous quantity of research data it holds, it has become a slow-witted Digimon with a large build, but it is probably difficult to bring down even if it is attacked by scores of Digimon. It is definitely an impregnable Digimon.[1]
