That this will be the type of image posted after the leaks...
I know you're probably just baiting, but this honestly seems more likely to happen soon enough. It's already exists as a usable pokemon with it's own states and was found via datamining in XY along with the move Light of Ruin, a fairy move (just like it's own type.) that only it can legitimately learn like most signature moves. Can easily see it being the small legendary or mystical that joins along with ash and the gang like past mini legends with Zygarde and Volcanion taking some part in the movie as well.
