Thor 3: Ragnarok
November 3, 2017
Beta Ray Bill, one of the surviving Korbinites, after Surtr and fire demons torr their galaxy apart. Surtr is most likely going to be the main villain in this film, which is why Beta Ray Bill would fit perfectly alongside Thor in the battle for Asgard. Maybe in the future we could also see Beta Ray Bill's role increase in the furthur MCU.
Surtr, the fire demon, who has been imprisoned, but perhaps Loki frees him from this prison and he runs rampant and he has his eyes set on destroying Asgard. This will be Thor's greatest and toughest battle yet so be prepared for one hell of a ride.
Hela, the Goddess of Death and creation of Loki. She could probably be a secondary villain to Thor behind Surtr.
Amora the Enchantress, she is in love with Thor but he is not with her, so out of jealousy and anger she uses her magical powers and mind tricks to make Thor in love with her. She could serve as a secondary villain behind Surtr.
Ragnarok could possibly be the movie to shake things up in the MCU. There are tons of questions going into this, will Thor die? Loki? Who will be the next one up to take up the hammer? Will Lady Thor appear? I guess we will have to wait and see...
