Glitched/missing textures have occasionally been reported on pokemon in X/Y and I'd assume that's what these are. There's also no indicator on the summary screen like the red star that shiny pokemon have. The other possibility is that yeah, they're shopped.

Duh. I hadn't thought of that. One more question: are you at or near a point where you can confirm/deny the existence of extra pokemon after Zygarde?

Are we to understand that the contest stats are gone? That would be a nail in the coffin for the idea of R/S/E remakes, unless they were to completely change Hoenn's contests or get rid of them entirely.
