7 Most Exciting New Additions To Thor: Ragnarok
6. The Sakaarans (And Maybe The Cotati)
The Sakaarans have already appeared in the MCU, with the alien warrior race working for Ronan in Guardians of the Galaxy, but we're going to be seeing a bit more of them in Ragnarok.
Although the specifics haven't been revealed just yet, there's a good chance the film will be paying a visit to their planet, Sakaar. After all, this plays a huge part in the acclaimed Planet Hulk storyline, which this movie will be borrowing elements of (since Marvel aren't going to do an actual adaptation of it, this is the closest we'll get).
Hulk' gladiator armour was revealed at Comic-Con, while IMDb lists Mollie and Sophia McGregor as playing 'twin Sakaaran citizens'. It may be that Sakaar is where we find the Hulk at the outset of the film, or that it's somewhere the characters travel to on their intergalactic road trip.
While unconfirmed, there are also rumours that the Cotati will also be appearing in the film. They're one of the oldest alien races in the Marvel universe, with telepathic abilities, and it'd make sense to see them (or similar races) since the movie is travelling around the cosmos.
