This is my dilemma. At first I was gonna disagree about a link to another x&y instalment for distribution in comparison to black & white kyurem, BC they weren't even in b & w's coding, genesect, keldeo, and meloetta were though. Some people say the god stone was a coding for bw kyurem in bw but there is actually an extracted image for said stone which is nothing like the DNA splicers ( last I read, this is going maybe two years since I read )
I was pushing strong against it not being distributed in the next instalment and that it would have to be in the x & y copies we have now because of it being coded, but then again, we didn't get none of the events for bw til bw2 ( might have gotten keldeo I think... not sure ) I know we didn't get meloetta til bw2.
But that's not even my biggest issue with my original theory, the biggest hole puncher against my theory is ...
Why on earth would AZ give it to you?
So I'm thinking, he will probably pass away in the instalment if its in sequel format and pass it on to you BC you remind him of xy protag bla bla. Or if its a prequel, floette could be with you while AZ is searching for it. Of course this would all be in short story format due to it being event legendary status.
Now if we get it in this game, in X & Y, I'm thinking AZ is gonna die.
