@ Emptylord: Well, shapeshifting is pretty much used to identify a champion (At least here on the Wikia) that either changes in-game form or changes kit and, in her case, she does the second.

I must agree with Gulgolet2000, but also add that she's likely the female with an unfemenine shape that Riot promised.
