Did any one of you guys ever get a shiny in G/S/C or HG/SS, excluding the red Gyarados?
Aside from red Gyarados, I do remember catching a shiny Hoothoot in Gold, Silver, and Crystal. Unfortunately, I can't quite recall what I wound up naming it, but I did wind up giving it a nick. Usually, I don't nickname my Pokémon, but when I do perform such actions, I do it because I find said Pokémon to be sort of special, which it is!
In HeartGold and SoulSilver, I think I might have encountered a shiny Scyther. I don't believe I'd managed to catch it, however, or I would have had it with me by now in my Y version, haha. I'm not sure why I didn't catch it, sadly. I probably didn't have enough Poké Ball?
