During their adventure, children Tai, Matt, Sora, Izzy, Mimi, Joe, and T.K., 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.
