So I was thinking, there are a few mirror match intros that just seem like the characters are confused about seeing their clones, like Ferra/Torr's "Why you look like me?"

But then there are others, where it really seems like one of the characters is pretty much admitting that they are NOT that character.
For example, when two Raidens fight each other, one asks, "Who are you?" and the other says, "I have many names."
And then when two Liu Kangs fight each other, one says, "Shang Tsung?" and the other says, "A feeble (or something) sorcerer? No."

There were a few other ones like that, and they clearly display a consistent kind of attitude like, "You don't know who I am, but I admit I don't actually think I'm you." And they never seem to be surprised at seeing another character looking exactly like them. I found this to be very intriguing that it almost comes off like some kind of a new shapeshifting character. I'm not sure they'll actually build on this and make a character out of it, but I think it'd be very interesting, if there was a sort of a being who could mimic other characters and manipulate others from inside their ranks. I think it'd be cool if they explored a character like that. I know there was Shang Tsung, but they seemed to have completely ignored the idea of Shang Tsung being a shapeshifter in the actual storyline, and didn't actually do anything with this potentially deceptive ability in MK9.
