As they wander further into the Digital World, the DATS stumble upon a ghost city which is home to a nest of Dokugumon. Without warning, the spider Digimon quickly trap the DATS and their partner Digimon, dragging them all into the depths below where their lord MetalPhantomon dwells. He casts the DATS into a world of endless nightmares and despair where their greatest fears take shape. In Marcus's nightmare, a Drimogemon was carrying away his sister, Kristy. Marcus tried to rescue her, but a Numemon got in the way. After Marcus punched it, it multiplied, forcing Marcus to punch it again and again. Marcus went after Kristy again, but was trapped by the Numemon, allowing the Drimogemon to escape.

In Yoshi's nightmare, she found her younger self, telling that she hated her family, that made Yoshi cry for sorrow.

In Thomas's dream, he was in the town that he lived with his mother years ago. He remembered the memories of the happy times with his mother. He remembered the tragedy of his mother's death. Thomas tried to stop his mother, but she couldn't hear him. As the younger Thomas and his mother were going to a festival, a speeding truck came by and accidentally killed his mother. Thomas, now what has happened, felt sorrow in his heart. After reliving the painful memory about his mother, Thomas' DNA awakens, granting Gaomon the power to digivolve into his Ultimate form, MachGaogamon. MachGaogamon defeats MetalPhantomon, and the DATS team escape from the gorge, only to find Yoshi has passed out.

Digimon Analyser

???: "Kuramon are In-Training level Digimon. Their uncanny ability to spread viruses in computer networks makes them real terror-byte terrorists."
Thomas H. Norstein: "Dokugumon are Champion level Digimon. They have computer viruses running through their bodies. They wait for their prey to sleep, then pounce on them with highly poisonous fangs."

Gaomon: "MetalPhantomon is an Ultimate level Digimon. He has an energy-stealing scythe that steals the life force of the living."
Thomas: "MachGaogamon is an Ultimate level Digimon. Two jet engines propel him at incredible speed. His special attack modes[please confirm] are "Winning Knuckle" and "Howling Cannon"."

"You decided to torture me with that tragic memory of my mom, MetalPhantomon...you'll pay! What you did was unforgivable. You forced me to relive my mother's horrible accident just so you could steal the essence of my heart! There are consequences for what you've done! Your evil ways must be brought to an end!"

Thomas H. Norstein prepares to show MetalPhantomon the error of his ways.

"Gaomon, warp digivolve to...MachGaogamon!"
