Okay, this is kinda weird, but I was trying to catch a Shiny Groudon. ANd I was wondering if the icon you see, will tell if it's shiny. So like the first time I saw it with Team Magma and it wasn't shiny. Shows that I won't get a Shiny, or will the Icon I see now in the cave, be shiny when I run into it.

Basically, I just need to know if the little Icon of Groudon, will be shiny when I see it, or is it in the battle mode state. Or is it Random, on how you catch it. Same with Rayquaza?
