Well, the official artwork does it justice... Getting a full look of it is always better... But my criticism towards it is not because of the design, it's that I would rather have this as a new pokémon rather than just a Mewtwo forme, which is most likely the case (Like it says in the front page, calling it a new pokémon is probably them just trolling like they did with the Kyurem formes). Cause I honestly think it looks cooler than the original Mewtwo... Curiously, I think it looks more similar to Mew than Mewtwo does (with the exception of the "tail" being attached to its head of course)... I'm more interested about its stats though because if it is just a Mewtwo forme, I wonder what they are gonna change about it...
@DasMisfits: Now that you mention it... How about this: Mewtwo looks like Frieza, this new forme or whatever it is looks like Buu... Just wait a few months (or gens), they're gonna reveal another Mewtwo forme that looks like Cell...
