I am restating an old arguement, so please don't flame me about reposting it. If you don't know about the Shao Kahn Reiko situation, then check out

Now in Mortal Kombat: Shaolin Monks, Kahn is unmasked in the last level to prove that he is not Reiko. It is also stated in Deceptions Konquest mode, that Reiko just likes to wear Kahn's cool helmet. Many people dismiss this as fake since Konquest mode has a lot none-cannon stuff.

Just some fun info, I e-mailed Midaway a right after Deception came out for gamecube about Kahn looking like he did in MK 2, with those little spikes in his head. Imagine if they actually listened to my advice!
