Sounds awesome. Have you thought about clothing? And, think you should make the Chatot a Wobbefet or however you spell that ugly mofo of a Pokemon's name, but the Chatot randomly popping out of its ball, quoting from random literature? That would add a little bit of lol to your character, if you could come up with something that wasn't completely from the Anime?
After all, if he is a character in a fic, a good thing is to make the reader laugh.
