I thought you just had to make a fakemon. o.o If that is true then it's kind of a weird concept, as the fusion can look like anything! xD
I thought it was similar to the Serebii one; an outline/silhouette is provided and entrants make a Pokemon from it. Is that not what this is? I assumed it was, due to the scoring system and 'give it a Pokedex entry' thing.
And on that note, I realized a problem with the sprite. Hang on, I'll correct it.
