History
Brunnhilde known as Valkyrie is an Asgardian goddess.[1] When the Maker settled on Earth-6160 to reshape it to his image, he facilitated the ascension of Loki to the throne of Asgard, killing Odin and imprisoning Thor.[2][3] Years later, after Thor was released and started the Asgard Rebellion against Loki, Sif released the Asgardian gods from Loki, taking refuge in Niffleheim, Brunnhilde joined the rebellion.[1]
