The Crest of Light

'''The kids end up separated in the sewers beneath Machinedramon's city. While Tai and Izzy run into an old friend, the others set out to free a group of Numemon from slavery.'''

Synopsis
Right after Kari wakes up and is back to health, Sora and Biyomon as well as Patamon show up, where T.K. and Gatomon have been taking carre of Kari. Sora also hands Kari the medicine that they found that Tai must have dropped, when they became separated. While exploring the underground labyrinth of sewer tunnels, Sora, Kari and T.K. come across a large group of Numemon enslaved by WaruMonzaemon. Kari glows with a mysterious light, and frees the Numemon and empowers the kids Digimon enough to defeat WaruMonzaemon. When Machinedramon is told of this defeat, he is furious and punishes WaruMonzaemon.

While Tai and Izzy are exploring, they run into Andromon, whom they had met previously in File Island. Andromon is leading a resistance against Machinedramon, and vows to help the kids. Machinedramon finally corners the DigiDestined and defeats Andromon with ease, as he then moves to strike down Kari, with Koromon and Gatomon too tired to help. Before he can strike, however, the hordes of Numemon swarm over Machinedramon. It is of no avail however, as Machinedramon swiftly kills every one of them. The deaths of the Numemon spurs the light in Kari further, and it powers Agumon enough to Warp Digivolve. With his power amplified to unbelievable level, WarGreymon brutally slices Machinedramon, and before he can strike back, he falls to pieces. With Machinedramon defeated, his city begins to disappear. The DigiDestined decide to erect a small shrine to honor the Numemon.
