Synopsis
When MetalGarurumon attacks Agumon, he is forced to digivolve to WarGreymon, and an unstoppable battle begins, with Tai and Matt lashing out at eachother. Meanwhile, Kari discovers some kind of presence nearby, which emits a blinding light, taking in the entire group. They then appear in a familiar region of Tokyo, Highton View Terrace, where a mystery being speaks to them through Kari. The group are told of how they were chosen as the DigiDestined after witnessing a battle between Greymon and Parrotmon four years ago. The being then takes them to room where hooded people control the balance between good and evil in the Digiworld, and the kids' future Digimon are in their DigiEggs. The group watch as Piedmon attacks the people, and steals the eight crests connected to the DigiEggs. They then witness a younger Gennai rescuing the DigiEggs and taking them to File Island (losing Gatomon's egg on the way), where they await the arrival of the DigiDestined. When the group arrive back in the forest, Matt leaves the others, saying he needs some time to himself. Mimi also decides to leave the group, refusing to fight anymore, so Joe decides to keep her company.

Miscellaneous trivia

 * WarGreymon and MetalGarurumon announce the episode title in the Japanese episode.
 * At one point during the flashback, Piedmon is shown inserting a small dark sphere into Gennai's upper-back. Though no explanation is given for this, it may have caused Gennai to age into the old man he's seen as in this series (the tubes on his back may also have something to do with it).
 * It's revealed that Gatomon became separated from the other Digimon after Gennai dropped her Digi-Egg, whilst escaping Piedmon's henchmen.
