I'm not really big on designing fake Pokémon, but I've had occasion to come up with a few.
Separate from the other fake Pokémon, we have The Eeveelution Project. Having once designed an Eevee evolution (Serebeon shown above) I found it to be rather fun and thought that drawing an eeveelution for every type which doesn't have one would be even more fun. Thus at last I began the Eeveelution Project, but it only got so far before I lost inspiration, and the eventual arrival of Leafeon and Glaceon in Diamond and Pearl really killed it. I'm not likely to continue it, but I leave it here as it was.
