Digimon

Digimon (デジモン Dejimon), or Digital Monsters (デジタルモンスター Dejitaru Monsutaa) in long, began as a series of Virtual Pets, that expanded into a franchise centered around the creatures living inside them that quickly eclipsed the popularity of the Virtual Pets themselves.

Based partially on the sister franchise, Tamagotchi, the idea was to raise a creature called a Digimon that would evolve and change form depending on how it was cared for. Digimon could be pitted against eachother in battle - the chief difference between Digimon and Tamagotchi. Digimon was designed to appeal to boys in the same way Tamagotchi were geared towards girls.

The term Digimon may refer to the video game franchise, an individual Digimon, or a species of Digimon.

=Evolution= See Evolution

Digimon evolve with age, collecting data, winning battles, or drawing energy off a human. Digimon have six "natural" stages of evolution as well as others obtained through artificial help.

While the anime generally presents Digimon as having conceptually "matching" evolution lines, in other aspects of the franchise, Digimon evolve depending on how they're raised - including what time they're awake, how much they've fought, how much they've trained, how much they've eaten, and other factors. An Agumon who has been raised properly will evolve into the powerful Greymon, while one who has been starved to death will evolve into the weak and disgusting Numemon. Evolution can be temporary or permanent depending on the circumstances. Generally in the anime, Digimon evolve for a short period of time before reverting to smaller, cuter forms. In the games, Digimon usually retain their larger forms after evolving.
