In the Marvel universe there are multiple Valkyries. They were warrior defenders of Asgard. As we saw in Thor Ragnarok they bravely faced off against Hela and we’re led to believe that Valkyrie was the lone survivor. As with everything in Marvel, there tends to be surprises.
I’ve learned today that Marvel plans to use the character Mist sometime in the future, and based on her background something connected to Thor is likely where she will pop up.
Created by the legendary Chris Claremont, Art Adams, and Terry Austin in the mid-80s New Mutants, Mist is a Valkyrie. In the comics she was a friend of Danielle Moonstar, one of the New Mutants and someone who appears in the upcoming movie; although it’s doubtful that connection will continue into the MCU due to Marvel planning a long reboot for the Mutants.
Instead, it’s likely that Mist will show up in something connected to Thor. Be it the Loki series that’s filming now, or more realistically Thor: Love and Thunder, or possibly something different. Perhaps a Valkyrie Disney+ series?
Wherever she appears, it seems that Valkyrie wasn’t the only survivor when they faced off against Hela, and we’ll soon meet another Asgardian in the MCU.
