Remember this? The guy who got those images is the same who few days ago ripped the alternate color models of Kalos legendaries: Smealum.
Now, since Diancie has been confirmed, I suppose he earned our trust.
Smealum likes to play with codes, but he never revealed anything about stats or whatever. So, the rumors about Megalatias Dragon/Fairy with Multiscale don’t come from him, and are only rumors.
Those Vivillons seem so cute, and I’d really like to get AZ’s Floette, with that black-n-red flower :3 MegaLati@s seems a bit too anonymous to me, but I really like Hoopa like Diancie. Not totally convinced about Volcanion, but maybe I just have to see it in my own game.
