Digimon(Digital Monsters)

Beginning:
Digimon  short for "Digital Monster" are mysterious lifeforms that were discovered in the Computer Network in 1997. They are central to the Digimon franchise. The word "Digimon" is typically invariable in the plural, though there are some cases where the term is pluralized as "Digimons". Digimon include almost all the creatures that reside within a parallel universe called the "Digital World." There are many different species of Digimon, as well as unconfirmed and new generations of Digimon yet to be revealed. The rate of new Digimon species continuously increase as the Digital World expands each year.

Characteristics:Digimon hatch from eggs called Digi-Eggs . They age via a process called "Digivolution" which changes their appearance and increases their physical powers. Some Digimon act feral, like wild animals. Most, however, possess human intelligence, speech, and personality traits. It was mentioned that, if a partner Digimon were to be separated from their partner, then they would start to become weaker.The first Digimon anime introduces the Digimon life cycle: they age in a similar fashion to real living organisms, but do not die under normal circumstances because they are made of reconfigurable data. Old Digimon and Digimon who receive fatal wounds dissolve into infinitesimal bits of data. The data then recomposes itself as a Digi-Egg, and the Digimon goes through its life cycle again. Digimon who are reincarnated in this way will sometimes retain some or all their memories of their previous lifespan. However, if a Digimon's data is "downloaded" as demonstrated in Digimon Tamers, in which all the data of a dying Digimon is absorbed by another, or if the data is completely deleted or destroyed, as happens in Digimon Data Squad, it will permanently die. In special cases, some Digimon do not get reincarnated despite their data still existing.

Digivolution is a legendary power and the process by which a Digimon "ages" and grows up into larger and more powerful forms. Although the word "Digivolution" is a portmanteau for "Digital Evolution", Digivolution is in fact more similar to metamorphosis in that Digivolution changes a Digimon from one form to another, sometimes wildly disparate form, very quickly.

Digivolution for Digimon is similar to aging for humans—it is generally a one-way journey whereby a Digimon will grow into a new form as they age and gain battle experience and data. However, moving from one form to another becomes progressively more difficult. Therefore, very few Digimon will ever naturally digivolve into their final most powerful forms.

However, for the Digimon who are partnered with human allies such as Tamers or DigiDestined, Digivolution becomes far more flexible. Digimon who form bonds with a human are able to digivolve more easily, generally through the use of a Digivice owned by the human. In such cases, the Digimon is channeled large amounts of energy and is therefore able to instantaneously digivolve to a higher level. However, these Digimon will generally de-digivolve or degenerate back into a lower form after a fight. Digimon partnered to humans are also commonly able to use special forms of Digivolution not naturally available, giving these Digimon many different forms. These include Armor Digivolution and Biomerge Digivolution.
