Digimon Adventure (デジモンアドベンチャー, Dejimon Adobenchā) (1999) is the first series of the Digimon anime metaseries. Its premise involves a group of boys and girls being whisked to a parallel reality called the Digital World while at summer camp. They were taken there because they were chosen to become DigiDestined, the children that would save the Digital World (along with Earth near the end of the series) from the evil forces that threatened to destroy it. Each of the children received a Digimon partner who was preprogrammed to be bonded to them, as well as miniature devices called Digivices. With the power of the Digivices, their Digimon partners could become stronger forms to battle enemies or save their partners from danger.

The series is continued with the same characters in Digimon Adventure 02.

Digimon Adventure was originally planned to have 13 episodes, as Toei Animation was not sure how popular it would become. As the ratings and popularity grew, it was extended to 54 episodes.
