Introduction
Its premise involves a group of boys and girls being whisked to a parallel reality called the Digital World (Or digiWorld for short) 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) 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.
Plot Summary
Traveling to the Digital World was an experience that left the children bewildered. Their Digimon partners were suddenly thrusted upon them, as well as the concept of having the Digimon Digivolve, a process by which they transform into stronger creatures to fend off enemy Digimon. Thus, the children had to learn how to be DigiDestined as they went along.
Soon they learned of the Digital World's plight, that evil Digimon intent on ruling it for themselves. They vowed to save it in spite of missing the life they had left behind. The DigiDestined promised to save DigiWorld because they saw that Digimon, though made of data, were as intelligent as humans. They did not want them to suffer; furthermore, it was demonstrated to them that no one else could defeat the Digital World's enemies.
As the plot evolved, the children dealt with various aspects of maturity: making friends, being courageous, standing for one's morals, etcetera. Each child was given an object called a "Crest" that embodied a particular personality trait that they had to demonstrate to get their partners to Digivolve to a higher level. It is later revealed that at the time they were chosen to become the DigiDestined that these traits were the strongest good trait within their personality.
