Dark/Flying is my bet, the color scheme from the new screenshot is pretty definitive. Doesn't seem Poison-type at all, and certainly no relation to Koffing... where in the world did that idea come from!? It's a fuzzy bat... not a poison gas balloon.
It seems that people decided it is related to Koffing simply because it is round... absurd of course. It's obviously not of the Koffing line, it's a new Pokemon.
Disagree with the Heracross evo... it really doesn't need one. And Heracross being underused currently doesn't make any difference when considering it's potential for an evo. Pinsir is the guy who needs the evo: Bug/Ground all the way! Pinsir would finally emerge from Hera's shadow.
Agreed! Although I wouldn't mind a Hera evo as well, I have been yearning for a Bug/Ground Pinsir evo for years lol. STAB Earthquake!
But I agree with you about the fire sheep, sounds like a great idea for a Pokemon. The only other typing (other than pure Fire) that could fit with a "smoke cloud" body would be Fire/Poison (hopefully with Levitate).
EDIT: @taicho: ...I think I've already seen that static-electricity sheep idea somewhere before... hmm, where was that...
Then again... Ampharos looks nothing like a sheep. Maybe instead of shedding its wool.. it catches on fire?
