At first, I was a little upset that both Mewtwo used Mega Mewtwo X, but then I realized that Shadow Mewtwo wasn't always Mega Evolved in battle. Maybe I missed something obvious, but I was under the impression that Shadow Mewtwo would always fight in his Mega Shadow Mewtwo X form (I think it was the fact that Shadow Mewtwo always seemed to be in Mega X state during his boss battle), rather than Mega Evolution being his Burst Attack. So, that means that both Mewtwo Mega Evolve into their Mega X forms for their respective Burst Attacks, which probably means that Shadow Mewtwo is a clone of Mewtwo in every way except stats. I suppose that justifies it, so I'm not terribly upset anymore. Sort of makes this post moot, I guess, but whatever
