Now Apocalymon

The group come face to face with the true enemy, and quickly discover that defeating him will be no easy task when they're robbed of their power and converted into data.

Synopsis
With the appearance of a new enemy, Apocalymon, the chosen children find one last battle. They're outmatched by the power of Apocalymon, who causes all the Digimon to de-digivolve to the rookie level before destroying the tags and crests belonging to the kids. Apocalymon then imprisons the children in the world of binary. Whilst there, the kids discover that they never needed their crests, as the power was inside them all along. So the Digimon digivolve once again, and break free of their binary prison, ready to take on Apocalymon.
