I think she actually was a beauty back then. Now she is a slutty beast. She tried to hide her Tarkatan features and never used them (unless it's a fatality). Now she is not afraid to jump on the opponent and reveal everything she should've hide. Not to mention that she doesn't resemble Kitana even though she was intended as her exact copy. P.S. I don't understand why did Shang Tsung create her so late (in new timeline). It was more reasonable to create her 10,000 years earlier (like in original timeline). Because Kitana was a baby then and it would be much easier to replace her (nobody would notice that).
