>>56534637Personally, I think evolution is more of an eventuality.
Let's put it like this:
>Babymon/1st stageMost Pokémon that are at this level can be either newborns or, like the Treecko tribe, Pokémon that weren't challenged AT ALL by the elements. Why bother to evolve when you have plentiful food, a secure roof, and live safetly inside a groove/well protected cave? Most of these Pokémon stay the same. They never had to endure anything.
>Mid evos/ 2nd stageThese are more stronger, and their anatomy changed accordingly. Their bodies turn bigger, more agile or resistant. They even add skills (2nd type) to their abilities to get a better upper hand against predators and the natural elements.
>Final evo/3rd stageNow these are the "oddities" of the Pokémon World. Some Pokémon are just "he became bigger", but others add limbs or modify their bodies to best their mightiers. But some also resemble human anatomy.
These Pokémon are more "self aware" and mentally active. I don't expect, say. Rhyperior to speak latin and read me The Illiad. But their main characteristic of having a peanut for a brain is gone. He also isn't as open to violence as his pre evos. I mean, he can destroy a lot, but he is relatively calm.
Other interesting example would be Blaziken. As Torchic, is a small chick. Destined to be served in Hoenn Flaming Chicken restaurants. But some evolve into Combusken. Now their legs are more fitting to fight rather than run.
But Blaziken is an evolution for fighting. His dangerous enemy are Flying types? I'll jump and punch you with ease (Sky Uppercut). I will also learn martial arts like humans do (Fighting type) so I can be on top of my game.
Continuing because I cook too much
