I just had a thought one generation too late… Since I finished Pokemon Black 2 in between having finished Pokemon X.
If between Zekrom, Reshiram and Kyurem, they all came from the same Pokemon… And the DNA Splicing Incident shows they can be put back together (You know, Black Kyurem, White Kyurem.)
…Then… We still don't know what it looked like all together… Some kind of Amalgam of All Three…
Is that… Ever going to be a thing? Like… Are we ever going to get a complete answer to that mystery? Or are we going to have to be content with what we know with just one little detail missing?
