I'm choosing Axew and Oshawott! n_n I swear if they make us play as Pikachu I swear to god. :(
I wish Hydreigon had a better role, perhaps has a villain. Look at it. A 3 headed being of destruction and they give it the role of running a shop... (I think that's his role, either way he's in the town thing).
Also Serebii said that moves can now level up. For example Thunder starts at level I and goes up to level III.
