A collaborative fan-made pokemon game, with original music, sprites and 229 original fakemon, including new abilities, moves and type combinations.
Incomplete Pokedex (image too big to embed haha)
The region and the pokemon are based on Southern and Central America and it really shows in my opinion, even down to the characters clothes and skin colour.
I'd highly recommend trying out the demo which can be found on the wiki
Some of the fakemon designs are SO good.
This one in particular I like because of how damn disturbing it is:
Brrr. Pretty sure Nintendo would never make a pokemon based on THAT parasite.
