Latios is hacked, I'm pretty sure. He has perfect IV's, and he was level 100 when I got him. Charizard may be legitimate. I got it from a random trade.
Hmmm, I'm kind of reluctant to get rid of Metagross though. I'm pretty sure he has perfect IV's, too. He one of my favorite competitive pokemon, so that's why I didn't list him at first.
I have no idea. I would value the pinwheel at a couple thousand bells, maybe? What kind of amount in TBT bells are you out looking for? We could base the shinies off of that first.
