One of the big new characters of Thor: Ragnarok is Tessa Thompson's Valkyrie. While she's serving Jeff Goldblum's Grandmaster when she first meets the God of Thunder, things are a bit more complicated than that; she's actually an Asgardian refugee herself, one who was part of Odin's elite force.

While the comic book Valkyrie is a blonde-haired warrior who is traditionally treated as a typical Asgardian superhero, the film version's Valkyrie moniker works like the title of 'Soldier.' "Our view of the Valkyrie in the MCU is that they were basically Odin’s special ops. His SEAL Team Six," producer Brad Winderbaum told Screen Rant. Her fight with Hela (Cate Blanchett) prior to the film left her on the planet Sakaar, and the demigoddess -- named SR142 -- has some lingering trauma when we first meet her, though she does want redemption and to settle the score. "It's the basis of her character," Winderbaum continued. "The fact that she’s here is due in large part to her story with Thor, and Thor getting her to that emotional place."

It's a radical departure from what comics fans are used to, but Winderbaum is confident it's the right choice for the character. "The idea of the Valkyrie and what they mean to Asgard and to Odin is something that we’re going to be leaning into a lot and draft a lot of ideas from the comics." No matter what happens, though, one thing is clear: Thor will definitely be a fan of hers.
