I've been wondering the same thing. This particular version of moemon uses sprites from several different "sheets," far as I can tell. I've found some pretty inclusive lists in the past, and there appear to be a couple of different options for Chariszard. The Charmander line thusfar uses a single source/style, but that's no garuntee: Caterpie used several different alternatives as it evolved. It makes the LP a lot more fun: I can make educated guesses, but no garuntees. It does make, for example, the bit with the mystery man on the cape with the dragonite tricky: do you know how many dragonite sprites I found? about 6 million, with rather different features.
