Mine was a shiny poochyena in Pokemon Emerald.
I didn't even know it was shiny at first lol. XD
As it was my first time playing any sort of hoenn region game
xd
Mine was a Shiny Torchic. Now it's a Blaziken and I gave it to my
friend, because I quitted but decided to come back. Now I have a
Shiny Gardevoir, Gallade and Houndoom
In Pokemon Soul Silver I've met a shiny geodude, but it used
explode and I couldn't catch him ... And in pokemon Red I've caught
a Zubat shiny. I've had the best crobat ever ... pink xD
First shiny I ever caught was a Girafarig in Platinum. Right before
the lake thats before that resort where it says there a blackout in
Sunnyshore, very first encounter. I was surprised it happened.
