We can capture our first Shiny Pokemon in the game, my first one was a shiny Froakie.

At first, you can't even tell that it's shiny, since the color difference is not much. I got him on my first playthrough of Pokemon Y as my original starter. When he evolved into Greninja, I thought that the black color was pretty cool. I still didn't even know he was shiny until someone told me.

This was such a rare opportunity. It's extremely rare to find a shiny Pokemon, and even rarer to get a Shiny Starter randomly. So, many players choose to Buy Shiny Pokemon to save time in the game. I gave him to my brother after I stopped playing, and I'm sure he's taking good care of him.
