Could be a Gym Leader, Elite Four member, Starting Trainer/Rival, Trainer Class, Professor, Battle Frontier Brain, Villainous Team member, etc. Just state who it is, and if you have anything to share, please do so.
I know there has to be at least one NPC you fancy, so share if you please.
For me, I find Chuck attractive. I find it admiring that he has such a dedication to training. And his physical appearances are quite appealing to me as well.
