I've run into a few. My first was a Camerupt in Platinum. Then after learning how to EV train, I've run into 11 shiny Bidoof. I mean... yay.... Bidoof. But I've gotten a few shinies in White. Timid lvl 1 Deino w/ Dark Pulse. Adamant lvl 1 Pawniard w/ Sucker Punch and a Modest Litwik. So I'm off to a good start.
