Please answer the following question: Generate a question about the following movie plot: The film is centered on Mortal Kombat, a fighting tournament between the representatives of the realms of Earth and Outworld conceived by the Elder Gods amid looming invasion of the Earth by Outworld. If the realm of Outworld wins Mortal Kombat ten consecutive times, its Emperor Shao Kahn will be able to invade and conquer the Earth realm.
