Pokémon evolving with their trainers... ADORABLE! I had my own idea similar to this for Halloween someday, with a cosplay-like thing based off one of my favorite Pokémon. I had Dratini, Riolu, Dragonite, Lugia or MewTwo in mind. :)
I've played every Pokemon game since the beginning of time and watched every episode of the show and seen every movie. My brother and I used to draw Pokemon on index cards and throw them in our yard and "fight" them when we "accidentally" stepped on them.
