My favorite shiny's are umbreon, sylveon, zouura, and cydaquil. Also shiny Mew, but I doubt there will be any event with it.
I do own 1 shiny [url="http://pokemondb.net/pokedex/krokorok"][/url] My boy krokorok, and so I randomly ran into him in my second pokemon game (black), I freaked out so much though that I had my brother catch it for me so if he made it faint it would be his fault XD. I've also done a lot of shiny hunting but no luck (rip me). I shiny hunt suicune in Alpha shappire (that's the one with the hoopa rings right?) and I finally ran into one but either my 2ds died or I ran out of pokeballs (also rip me). Actually I have another shiny which is the rare-and-elusive-totally-not-part-of-the-story-line shiny gyarados. I also kinda cursed myself since I had transfered krokorok for black to x and played pokemon amie with it. So while I was in pokemon amie I acidently covered up krokorok's snout and found out that he really looks like Dora.
