Four years after the events of Digimon Season 01, the Digital World is invaded by the Digimon Emperor, who is enslaving Digimon with the Dark Rings while building Control Spires that prevent Digivolution. To fight him, four new DigiDestined (which includes Daisy's identical twin, Brittany) are recruited, each gaining an ancient Digimon for a partner. The four, along with T.K. and Kari, each possess a D-3, a new type of Digivice that allows them to open a gate to be transported to the Digital World through any computer. They are also given D-Terminals that hold Crest-themed Digi-Eggs that allow their Digimon partners to undergo Armor Digivolution to counter the presence of Control Spires . And romance will blossom between Matt, Davis and the twins.
