Chespin (shock, surprise, awe) for the Twitterdex. I always wanted to do this kind of thing on my own, where you draw each and every Pokemon. But I tried doing it back when there were 151 Pokemon and always fell short. Now there's a ton more, so the failure would only be magnified.
The funny thing is I beat X/Y, and I still don't know half these guys. Since when are there over 700 kinds! Insane.
