Darth Vader vs Original Cenobites
Darth Vader discovers the LeMarchand cube and his sith powers sense there is something evil and powerful in it so he opens it and is faced with the original Hellraiser cenobites. They know the evil he has done and want his soul to torture. Vader obviously isnt going to let them and is at the height of his sith powers. Who wins.
BTW i dont know how he discovered the cube. he just did.
