For the handsome hero's third standalone installment in the Marvel Cinematic Universe, he's losing his long blonde locks in favor of a much closer cut, and his armor is getting a gritty, leather-clad upgrade as well.
Star Chris Hemsworth debuted the new, more Spartan style on the cover of this month's Entertainment Weekly, where he was flanked by Cate Blanchett -- who stars as Ragnarok's main villain, Hela, the goddess of death -- and Tessa Thompson, who plays the warrior Valkyrie.
While the hair and the outfit are pretty big changes, it also looks like the Norse god has been forced to trade in his beloved battle hammer Mjolnir for a pair of particularly threatening swords.
However, Thor's accessories aren't the only thing that's going to be different in the upcoming action epic. Director Taika Waititi -- best known helming the indie comedies Eagle vs Shark, What We Do in the Shadows and Hunt for the Wilderpeople -- told EW that the film will have a slightly different tone than previous installments.
"I think sometimes people mistake a tonal shift as, 'We're just going to make some ridiculous broad comedy where no one gives a s**t what happens and everyone gets stoned and sits around talking about saving the universe,'" Waititi explained. "We want people to care what happens and care that the hero succeeds."
