Thus far, the Thor films are considered to be the weakest ones in the entire MCU franchise "“ and this is mainly because of inconsistent plots and less than average acting. Nonetheless, the God of Thunder has a chance at redemption in 2017, when the last movie of the trilogy will be released. Even Kevin Feige said that Thor: Ragnarok will be something like the main event of Phase III, outside of the Infinity War movies.
While this particular trilogy (unconcluded yet) has introduced the best Marvel villain yet, it has shown that it cannot give the audiences a character powerful enough and who can actually pose a threat to the mighty Thor. The main fight of the first flick was against a pretty much entirely depowered Destroyer (when compared, of course, to the comic books version), while The Dark World almost replicated the scenario.
If the first movie showed the Frost Giants trying to take over Asgard (or something thereabout, since the plot made little to no sense from this point of view), the second one showed the Dark Elves trying to do pretty much the same thing, with the ultimate goal of bringing darkness to the entire universe (again, from this point of view, The Dark World suffered also). What will happen during Thor: Ragnarok, which could make this the most important flick of Phase III?
Well, we do know that Thanos is coming and that he needs to both take the Tesseract from the Asgardians, as well as defeat them, since they are the protectors of the Earth. But does this mean that the Mad Titan will become himself involved in the battle, as teased in the Age of Ultron credits scene? Or will he scheme throughout the flick, like he did until now?
We believe that it will be both, with him making an appearance to deliver the finishing blow. But who will be his minions? This list is all about that "“ so check out the rumored villains for Thor: Ragnarok, the villains who have the most chances of appearing in the movie.
