Buntbro is a pretty unique little critter because if Pokemon Wind an Rain were made into a games they would be a hard hitting SPECIAL attacker. Not only that but because of their whole gimmick they can actually learn just about every move that has "ball" in its name.

As a last point their name is a mix of bunt (a baseball move where a batter lightly taps the ball rather than hits it with extreme force). The bro part is not only because backwards facing cap like plumage on it head but the scientific name for Northern blue jays is Cyanocitta cristata bromia.
