Mine was a Shiny Wurmple in Pokemon Sapphire. That was the time I was playing a Pokemon Game for the first time, so I didn't know anything. After I saw a normal Wurmple, I saw a purple one (shiny) and I was like what the heck? Are there two kinds of Wurmples? Plus that time, I didn't know what a 'shiny' was, so I just ran away from the Shiny Wurmple which was a BIG mistake. And the Sapphire game was my cousin's and I told him that I saw a purple wurmple and I ran away from it. Then my cousin got surprised and told me that it was Shiny Wurmple, so now I know what a Shiny was. Then my cousin got pissed off because I didn't catch the Shiny Wurmple and ran away from it. Dude, I didn't even have any PokeBalls, so there was no way I could've caught that Shiny Wurmple. So yeah. That's all. Plus the first Shiny Pokemon I got without Pokesav was a JAPANESE red gyarados.
