Why does the Pokemon thing have to be a part of it? Just ask her out like you would anyone else.

Don't be positive or negative about it, just mention it under the guise of something you saw online (on one of those more- uh- popular sites that won't terrify her) and see if that catches her attention or not.
Worst-case scenario, she thinks nothing of it and you move on with your life.
