The Gym Spectator.

Well in B/W he gives you a bottle of water I think and since I'm too greedy/lazy to buy them myself lol I always talk to him beforehand XD

Would be awesome if he turned out to be the champion in one of the storylines, he would be the perfect opponent after watching you battle so many times and knowing your battle style.

That'd be cool, actually. I think it might be nice to have him help you all the way through, then he's the last gym leader. I always talk to that guy, I'd like to see him in a better roll. ^^
