>>19758972That may be true but there are at least slight variations within some species, and sometimes drastic ones from region to region. Consider the more common > rare variants to just be regional variants on the normal coloration and the very rare > shiny level ones to be mutations. And this is all considering the fact that "It's Pokemon. I ain't gotta explain SHIT." Dude, Shellos is the same species and has not only two colorations but even different morphology based solely on which part of the sea it was born in.
I think Gen 6 is a step in the right direction, introducing the Flabebe line, Vivillon, Gourgeist and Furfrou, all of which have form differences based on different things. I fully support the idea of multiple subtle shade differences in pokemon, and now that we've moved to models that are dynamically colored, it's easier than ever to simply program a handful of similar color possiblities and a slowly increasing level of rarity the further from the base color it gets, until you hit shiny level. Throw in some basic form differences for some pokemon and you've instantly got a much wider variety in the world, and the game doesn't seem so tedious anymore having to look at the same exact pokemon over and over. Now you can get excited when you run into a color variant you've never seen before and try to catch it for your dex, or bump into a pokemon with your favorite color variant that has a slight form difference that you don't have yet. Lots of fun to be had with this if gamefreak would just put in the tiniest bit of effort. Plus it would solve the issue of lackluster shinies that nobody likes having an alternate version. Personally, I'm waiting for the day when shiny Gengar gets his mega's color. White normal Gengar (And his whole line for that matter) would be sweet.
