The Ultimate Clash

Before WarGreymon and MetalGarurumon manage to tear eachother apart, a mysterious being transports the entire group into the past, where the kids discover how they came to be the DigiDestined.

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, and begins to converse with the mysterious entity, which has been trying to communicate with her for a while now. It tells Kari to raise up her Crest of Light, so she does, emitting a blinding light, and taking in the entire group. They then appear in a familiar location, 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 stay with her.
