Digimon Adventure 02: Diablomon no Gyakushuu

Years after Diablomon's defeat, the malicious Digimon suddenly returns to the network and begins spreading copies of itself through phones, computers, and every connected screen it can reach. Taichi and Yamato once again enter the digital battlefield with Agumon and Gabumon, but their old enemy has learned from its previous loss.

While Koushirou and Ken try to understand Diablomon's new plan, countless Kuramon begin appearing in the real world, turning the attack into a threat to Tokyo itself. The older and newer Chosen Children must work together, combining Omegamon's strength with the powers of the new generation before the multiplying virus can complete its revenge.
