Lucky Fire, no offense taken.
On my very first day of getting Diamond (22 Apr 2007, its day of release), I was in Eterna Forest traveling with Cheryl, and I get to the point where you pick up the Great Ball. I start to leave the grass...and I get into a double wild battle with 2 Buneary, one of each gender. And the male one's SHINY. I near freak out.
I find out that in a double wild battle you can't capture until one of them is gone, so I get rid of the female one pretty quickly. However, you can't control the Chansey partner, so she would keep using Egg Bomb.
It got to the point where the Chansey would kill the shiny one on the very next turn, so I select my only Great Ball, let fly, and cross my fingers.
I CAUGHT IT. SUCCESS.
It's now a shiny male Lopunny on my Diamond save file. And since Lopunny are pink...you can see that it really makes no sense. (Its nature is Sassy, its ability is Klutz, and its stats are horrible...but it's shiny.)
