They're probably not going to introduce Marvel or Star Wars characters into the show because they are an established brand within the show's universe. If they were to do Thor for example, it would be their version.

This may be the final season of the show, so the villain can't just be random - it'd probably have to link with the shows mythology, the way Fiona was (inevntor of the Dark Curse, Rumples mother, history with Blue, etc).

That being said, even though the season will have a Big Bad, it can have other minor villains too (like Jafar in S6). I would love to see the Big Bad Wold from Red Riding Hood - we know Granny's hubby was a wolf, so maybe they could link it to that (and after being on the show since Pilot, I think she deerves a backstory)
