Re: celebrity guests???
Celebrity guests are usually reserved for the Simpsons only. But I have seen on Justice League celebrity voices like Michael Rosembaum of Smallville's Luthor does Flash. I"m not sure of any celebrity voices on Pokemon, or anything of celebrity guests. However, a gym leader is usually a celebrity in Pokemon, right? I'd love to see Claire again, riding on her Dragonair.
