I have two legit shinies:
I found a shiny Bidoof in PT, caught it, and it sits in my PC for no reason.
I also have a shiny Unown ( letter H) in SS. It sits in my PC also.
(Not to mention legit Red Gyrados and Pikachu colored Pichu, and hacked Shiny Tauros and Shiny Hippopotas, Before my AR broke on me...)
