Development of a Pokémon Fanon

Pokémon can undergo Evolution, process in which they suffer a sudden, systemic transformation into a new shape. This process and the shapes they can progress into are determined by species.

Evolution is one of the two paths a Pokémon can choose to follow by releasing an enormous amount of “typeless” energy they have stored for a long period of time during their lives, the other form being ${LIMIT_BREAK}.


Pokémon are, for the most part, in control of when and how do they want to evolve. When not, the process might be triggered by stress (such as needing the energy release to heal a serious injury) or age (reaching a given state of maturity). Requisites for evolution are mostly uniform across species and involve having reached the previous evolutive stage (so no eg.: Digimon’s Warp Evolution) and having the required energy intake or store to carry out the process.

Evolution can change all physiological and psychological aspects of a Pokémon specimen. In drastic cases, Evolution could wipe out memories or skills learned by the individual. The psychological changes can result in the emergence of whole second personalities or consciousnesses (eg.: Dodrio), or the loss of separate / multiple identities (eg.: Beldum).

Evolutionary items, such as the Type Stones, basically serve the same purpose as Gems - they give a Pokémon a strong surge of the type of energy needed to trigger that evolution. Without a Type Stone, most Pokémon that evolve by stone would need a very long time or fulfilling very specific requisites to reach evolution in the wild, sometimes even making it unfeasible to reach evolution under their lifespan in the wild.

Cultural Aspects

Most species regard Evolution as a sacred event -a remainder of the old eras and a means to become closer to their original beings-; even in the wild, if a predator sees that their attack has triggered your Evolution, he will wait patiently for it to finish or in certain cases just forgo your life, turning tail and gone looking for another prey.

Outliers include Scyther seeing evolution into Scizor as an aberration in the wild (they lose their speed, stealthiness, natural camouflage and elegance), and most “Starter” Pokémon seeing evolution into their final stages as unnecessary or thankless because they stop being small and cuddleable and in exchange they become less fit to perform activities with their humans other than competitive battling.


Certain Pokémon with the power and knowledge of how Evolution works can dispense the inverse process: De-volution, where a Pokémon’s power is released to the environment and his shape returned to an earlier stage. Most Pokémon, including Legendaries, see this process as cheating or flat-out “evil”.

Because only the morph / stages and the upwards evolution paths are encoded within a Pokémon’s biological information whereas the de-evolution path is not, the process is unnatural and extremely dangerous to undergo, and needs to be administered externally. Unlike with normal evolution, undergoing de-evolution can (or will) kill an injured Pokémon.
