During their adventure, children Matt, Sora, Izzy, Mimi and Joe discover that they are in a land where digital creatures called "Digimon" dwell. Befriending seven other Digimon, the children learn that they have the ability to help their partners digitally evolve (digivolve) into stronger, powerful forms that can combat enemies for a short amount of time. Setting off on their journey, the children start searching for a way home.

Plot
The children later learn that they are the "DigiDestined", chosen children with compatibilities with Digimon, and they are the only hope in destroying the evil that is slowly consuming the Digital World. When the culprit reveals himself to be Devimon, who sent Black Gears that would brainwash other Digimon into attacking them, he begins targeting T.K. and Patamon, as the two have the most effective power against him. Fortunately, Patamon, as Angemon, defeats him at the cost of his own life and is reborn as a Digimon Egg. However, Devimon is only a pawn in a greater threat, forcing the DigiDestined to move out across the world.
