With Gray Version (likely) around the corner, we may finally find out whether all that speculation is truth or not. Before then, though, discussions about theories are always fun, so let's do just that.

What theory, if either, are you more in support of? The theory that Kyurem, Reshiram, and Zekrom were all one dragon, or the theory that Kyurem is indeed just some icy dragon from space? Or maybe you have your OWN theory on the origin of Kyurem. Post any thoughts you may have here.
