Oh Nintendo, I don't know if it was intended, but that sure is a similar model to a specific new line of pony. I'm going to catch one and call it... Applejack.
Outside of playing the games, I haven't done a whole lot of pokemon digging. Apparently this is going to be one of those event legendaries released online and at various stores as an exclusive. It's also a leak, so no telling where exactly it will show up! Hopefully you poke-fans out there can get your hands on one!
Update: Apparently this dude is pretty old! Shows how much I follow pokemon these days!
