A shiny Pidgey on Yellow(Rt 1 or 2 or sth, before Viridian Froest), while grinding for Brock.
A shiny Weedle in Silver. It was the first wild Pokémon I ran into in Silver after getting Pokéballs. Given that I played back then as a Bug specialist and didn't use any other Pokémon except my starter (before I got my bugs), it was a really special moment for me with that game. That Pokémon became the very first I actually raised all the way up to Level 100.
神出鬼没 - shin shutsu ki botsu
You people get shinies early as hell in the game. I didn't meet shinies at all in most of my games, and in the one I did capture one, it was on my 80th hour or something, having completed the Nationaldex at least 20 hours beforehand.
And, as with all my angry tirades, the one I met at under the 15th hour, the game just had to kill it with a damn CR...
The first Shiny I caught was not the Gyarados...because I made it faint. :-S
Didn't even know I was supposed to catch it, or what Shinies were.
Later I found a Shiny Slugma in Emerald though I didn't KNOW it was shiny, and still didn't even know what Shinies were. But I caught it, and it know lives in HG. ^_^
Then a few weeks ago, I found a Shiny Magikarp! This brings my total number of legit shinies I have personally caught to 2. I do have some more that I traded for, however.
I don't ever remember a shiny in my early, early days, and besides the Gyarados in my original Gold game, my first (and completely legit, random, and unexpected) shiny was in either Diamond or Pearl, in the Lost Tower. I was just trying to get away from the place after getting my HM, and I ran into a purple, sparkling Murkrow. (Of course, it had to be the Pokemon notoriously hard to capture.) I had lots of balls (go ahead and giggle), and ended up catching it with what I believe was some ten balls away from my last. Needless to say, I was fricken ecstatic. C'mon, PURPLE!
In my first SoulSilver (sadly with all my best Pokemon and now lost), I remember being in the Safari Zone, using objects to my heart's content, when I ran into a tan Rattata. I was like, "Oh yeah!", because Rattata is easy to catch and won't even have a chance to run away. Caught it!
Then, in my SoulSilver II, I was going into Union Cave to train and stock up on entries before my Bugsy battle, and I saw a green Zubat. Awesome, right? Caught it easily, and this one, at least, still resides in my PC, completely within my access. I realize I've been, pretty much, the luckiest person ever to see, let alone capture, three unexpected shinies without even trying, and I thank the PokeGods (a.k.a. GameFreak) for allowing this to happen.
My first shiny was a Bronzor in Pokemon Diamond in Wayward Cave. I freaked out. It was around 2009.
I have never had a shiny that wasn't the red gyrados.
A shiny Weedle in my Silver version.
