To back up evidence of reality, it is some well-known french-speaking hacker who made a wild encounter modifier. He won't release it so peeps won't be hacking anytime soon.Hoopa's right horn (our left) has no lighting or shadows and is just one solid color, which I find to be a bit odd.. but I don't know, these look fairly convincing. The only question I have is how they were hacked to appear in the wild (if they, well, are real).
I can definitely see the Carbink/Diancie connection, and wouldn't be surprised if Diancie is actually just Carbink's evolution. None of them really strike me as being legendary though, but that is just me.
Good on him I suppose. He just wanted to leak these and nothing more, and he doesn't want the game to be cracked open, which I respect.
