I saw that info on Bulbapedia (which is much better than Serebii).
The "Overconfident" ability is pretty cool, hopefully Meguroko will be a good enough Pokemon that it can really use that ability.
Pretty interesting that it seems like the starting professor will be female this time, and that random online battles will actually happen.
Mamepato sorta looks like Starly. I guess that will be the standard early level bird Pokemon (like Pidgey, Hoothoot, Tailow, and Starly were).
