y'know, I think it'd be really cool if they made a pokemon based on the term "wolf in sheep's clothing" by making it have different forms, the first form being a sheep thats slow but bulky and has a special move that's based on countering, and when the conditions are right (health/status condition) it changes into a wolf form and sacrifices its defenses for high speed plus attack stats, and the move changes into a sucker punch-like move. Would be REALLY cool if it starts as a normal/fairy (sheep) into a dark/fairy (wolf)
A bunch of people were hoping Wooloo would go in this direction when it was first announced. Though in all honesty I have no idea if they know that phrase over in Japan or not
