Besides Gyarados in second gen. games, I've only ever found a shiny Zubat in Gold (which, actually, idk was shiny or not; I ran away from it to see if it was shiny XD), Floatzel in Diamond (while looking for a Ditto), Girafarig in Japanese Plat., Abomasnow in American Plat. (while looking for a female Absol), and now this.
Then the rest were cheated or traded. So they don't count.
Oh, and Combee, Abomasnow, Girafarig, and -technically- Floatzel weren't found with the Poke Radar (I was using the Poke Radar in Diamond for the Ditto, but I didn't do any chaining, this was the first Pokemon I found; I don't even recall the grass changing a different color to indicate a shiny was there). In fact, Girafarig and Combee were found before beating the game (and Combee was found before even battling Gardenia, which I still have yet to do XD).
Oh, and Abomasnow and Floatzel were found on events. Floatzel was found on my mom's b-day (and the day I got Explorers of Darkness), and Abomasnow was found on the 4th of July (now if only its eyes were red, then it would've been patriotic >.>).
