Synopsis

The DATS stumbled upon a ghost city, a haven for Dokugumon. Without warning, the spider Digimon ensnared the DATS and their partner Digimon, dragging them into the depths where their lord, MetalPhantomon, resided. He cast them into a realm of unending nightmares and despair, where their deepest fears manifested. As Thomas relived a painful memory of his mother, his DNA awakened, empowering Gaomon to digivolve into his ultimate form, MachGaogamon.
