Well, she does appear in the game and has some participation...
Her moves include a mystical fireball that has dark ashes coming from it and her famous Frontflip split kick. I imagine her variations from the kombat pack will be a magical one, an acrobatic one, and a mixed/fresh one.
As for her clothing, it did go through a major rehaul, but I think her clothes in MK4 were not really... original, or had any cultural value considering Edenian costumes. But then again, nobody knows how Edenia was. Let's see how she fits in the game.
