It's a shiny pokemon. You should catch it, as shinies are very rare! :)
Once you have beaten the game there is an island that you will find rare Pokemon and you will catch an evve which you can use the moonstone or other stone to make it evlove. The only evolved form you can catch of eve is umbreon.
you cannot catch wild rare Pokemon in xd but you can catch the trainers rare Pokemon, if they are "inpure"
It is rare, but it is so random. Just keep walking in the grass it'll eventually come up. Plus you might walk in the grass for about 20,000 times before you get it. That's how rare it is.
