I don't know if Bill's going to be the main threat (so far we've only see him team up with Gideon, not sure if the main villain handle should be given to him)

So far the bosses that are kind of more or less out of the picture (they are featured in other modes, but really shouldn't be considered for story mode):


 * Elf King
 * Landshark
 * Mandy Soul
 * The Fusionist
 * Master Hand
 * Enderdragon

Previous villains that shouldn't be used again unless we have a good story in mind for them:


 * Dr. Doom
 * Galactus
 * Venom

Villains that are in story mode in some capacity:


 * Bill Cipher
 * Lelouch
 * Shao Kahn
