I have just one tho. But that's not a plot, but just ideas for trainers. Cosplayers anyone? Fangirls/Boys (replacing those goshdarn Pokéfans), variations on Super Nerds... The variety is huge!
He heh... And a Gym leader based on me (as I act in-game in battles), of course... (strategic, rarely showing any emotions when battling, stating 'I see', and that if I lose, then that definitely means the opponent is a good one. And always uses the opponent's weaknesses to strike :D
Ahh... Oh, and if you look in one of my albums, you can find art for a champion with Weather Pokémon. Feel free to use some ideas XD
