Basic Premise: The Evil God Mother is angry that Cinderella became a princess, and in her anger, went to the mirror to find "the most ruthless slasher of all", to kill Cinderella for her. This spins off a grand tournament where all the most famous slashers (Jason Vorhees, Mike Myers, Freddy Krueger, Chucky, the Wishmaster, etc.) kill OTHER Disney Princesses for the grand prize of being the one to kill Cinderella. Of course, things will go very much wrong, and all the world of Disney will suffer. Likely very messed up. Interest?
