My first time going through Diamond, I got a Shiny Female starter. Yeah. I had seen the concept art of Chimchar, and I knew that he wasn't supposed to be a weird maroon-esque color. At this time, I hadn't heard of shinies. I had played Ruby, Sapphire, LGFR, Gold, etc. and STILL had know idea that shinies existed. So, I restarted. I thought something was wrong with it.
No, its not done yet......
I restarted again, and got, guess what, another shiny starter. Reset...
Nope, we still aren't done. I didn't get another shiny starter, however the first wild pokemon (Not that Starly that attacks you), was a shiny. I KOed it, and found another one. I thought that the second one was messed up :P, so I KOed it, and reset my game, thinking that it just existing would have completely destroyed every fiber of the earth.
So yeah, 3 shinies in one day. All right down the drain, and lost into history.
Only shinies I have found to date, except a Shiny Zekrom in Black.
If only I could turn back time.....
