Valkyrie, also known by her Asgardian name Brunnhilde, is a superheroine appearing in American comic books published by Marvel Comics. Created by Steve Englehart and Sal Buscema, the character first appeared in Defenders #4 (November 1972). She is based on the Norse mythological figure Brynhildr. Valkyrie became a mainstay of the superhero team known as the Defenders and a close ally and one-time love interest of the god Thor.

Valkyrie was selected by Odin to lead his personal unit of shield-maidens, the Valkyrior. Renowned for her prowess in battle, Valkyrie is often accompanied by her winged horse Aragorn and carries the enchanted sword Dragonfang. In the 2010s, Valkyrie became a founding member of the Secret Avengers and co-leader of the Fearless Defenders with Misty Knight. Among Valkyrie's other aliases are Barbara Norris, Samantha Parrington, Sian Bowen and Annabelle Riggs, who all, at one point, hosted her spirit. Samantha Parrington, one of Valkyrie's previous hosts, later received superhuman powers and became a member of the Defenders herself.

Tessa Thompson portrays the character in the Marvel Cinematic Universe films Thor: Ragnarok (2017), Avengers: Endgame (2019), Thor: Love and Thunder (2022), and The Marvels (2023). Thompson also voiced alternate variants of the character in the Disney+ animated series What If...? (2021–2024) and the television series Marvel Zombies (2025).

Publication history The Valkyrie first appeared as a guise of the Enchantress in The Avengers #83 (December 1970) and was created by Roy Thomas and John Buscema. Thomas used another iteration of the character when the Valkyrie persona was placed into a mortal woman named Samantha Parrington as an adversary for the Hulk in The Incredible Hulk vol. 2 #142 (August 1971).

Roy Thomas publicly stated the character's creation, "I wanted a sort of female Thor, but of course at first I just made her a disguise of the Enchantress in THE AVENGERS. I left the look mostly to John Buscema, though I may have said I wanted her to be blonde."

Writer Steve Englehart and artist Sal Buscema put the Valkyrie's essence into another mortal woman, Barbara Norriss, in The Defenders #4 (February 1973) and had the character join the group as a longtime member. Englehart has stated that he added the Valkyrie to the Defenders "to provide some texture to the group". Steve Gerber introduced Jack Norris as the estranged husband of Barbara but the Valkyrie persona had no memory of him. Writers David Anthony Kraft and Ed Hannigan explained some of the Valkyrie's backstory in The Defenders #66-68 (Dec. 1978–Feb. 1979). Three years later, writers J. M. DeMatteis and Mark Gruenwald wrote a follow-up story in The Defenders #107-109 (May–July 1982) which resolved remaining plot points from the Kraft and Hannigan story.

The Valkyrie remained a member of the Defenders through most of the series' run and is apparently killed in the final issue, #152 (Feb. 1986). According to writer Peter B. Gillis, the Valkyrie's death was part of an editorial edict to free up the surviving Defenders for use in X-Factor. The character was restored to life in a Doctor Strange storyline written by Gillis in 1988 and made only a few appearances in the 1990s.

In 2001, writer Kurt Busiek and co-writer/penciller Erik Larsen revived the Defenders series and restored Samantha Parrington as the mortal incarnation of the Valkyrie.

The Valkyrie's Asgardian iteration was restored in a one-shot comic book and the character appeared regularly throughout the Secret Avengers series, from issue #1 (July 2010) through its final issue #37 (March 2013). Valkyrie appears in the 2013 series Fearless Defenders by Cullen Bunn and Will Sliney.

Valkyrie began appearing as part of the Asgardians of the Galaxy team in 2018, and she plays a part in the War of the Realms storyline in 2019.

Fictional character biography Brunnhilde was selected by Odin, King of the Gods of the realm of Asgard, to lead the Valkyrior (the Choosers of the Slain), a group of warrior goddesses who would appear over the battlefields of mortal worshippers of the Asgardian gods and choose which of the fallen were worthy to be taken to Valhalla, the land of the honored dead. Brunnhilde served capably in this capacity for centuries.

According to a sentient, disembodied eye that claimed to have once belonged to Odin, the Asgardian monarch once gave his son Thor the mortal identity of the warrior Siegmund. Circumstances forced Odin to decree that Siegmund must be slain. Brunnhilde, recognizing that Odin was acting against his true wishes, sought to protect Siegmund, but Odin himself then caused Siegmund's death. Brunnhilde helped Siegmund's pregnant lover, Sieglinde get to safety. As punishment for her defiance, Odin removed Brunnhilde's Asgardian powers and immortality and cast her into a trance. She was eventually awakened by Siegfried, the son of Siegmund and Sieglinde and another mortal incarnation of Thor.

Brunnhilde and Siegfried became lovers, and she made him invulnerable so long as his back was not turned on his foe. Siegfried fell under the influence of magic and betrayed her. He was later murdered, and Brunnhilde, still in love with him, leapt into his blazing funeral pyre (this part of her background was based on the Volsunga saga). Odin restored both of them to life, restoring their Asgardian roles and powers, but removing their memories of their earthly lives. It is unclear how much truth, if any, there is to this account by the eye.

Brunnhilde and her fellow Valkyries continued to gather heroic mortal warriors for Valhalla until roughly a millennium ago, when Odin was forced to cease virtually all interaction with the Earth in accordance with a pact that he and the leaders of Earth's other pantheons of gods made with the extraterrestrial Celestials. From then onward, the Valkyries could only choose slain heroes from among fallen Asgardian warriors. Brunnhilde was bitter over being barred from choosing warriors on Earth and roamed Asgard in pursuit of something meaningful to do. In a tavern on the outskirts of Marmoragard, Brunnhilde encountered Amora the Enchantress, who offered her a life of adventure. For several weeks Brunnhilde accompanied the Enchantress on her conquests. Brunnhilde soon discovered Amora's immoral nature and tried to end their partnership. In response the Enchantress trapped Brunnhilde within a mystic crystal of souls. While Brunnhilde's body remained in suspended animation, her immortal soul became Amora's plaything. Over the centuries the Enchantress used Brunnhilde's spiritual essence to give the Valkyrie's powers to herself or to her pawns.

Specific instances of Amora's exploitation of the Valkyrie before recent years are not yet known. The first time the Enchantress assumed the Valkyrie's physical aspect in recent years was in a plot to lead a handful of female superhumans against the male Avengers as the Lady Liberators. Her true identity was discovered and her plan thwarted. Months later, the Enchantress bestowed the Valkyrie's power on socialite Samantha Parrington in an attempt to get revenge on the Hulk.

Finally, a woman driven mad by being trapped in another mystical dimension, Barbara Norriss, was given the Valkyrie's power and consciousness by the Enchantress to help her then-allies, the group of superhumans called the Defenders, escape from the clutches of the sorceress Casiolena. Amora did not undo her spell on Norris after Casiolena's defeat. As a result, Norris' body now possessed Brunnhilda's consciousness, appearance, and powers, while Norriss' own mental essence was trapped in Brunnhilde's real body in Asgard. Aware that she was an immortal essence in a mortal woman's body, the Valkyrie briefly left the Defenders in an attempt to discover Barbara Norriss' past. She meets Norriss' father, Alvin Denton, shortly before his death and then returns to the Defenders.

After Asgardian warrior Ollerus attempts to take over Valhalla, the Valkyrie's two mixed aspects met for the first time. Brunnhilde's mental essence, trapped in Norris's transformed body, fought Norriss' mental essence trapped in Brunnhilde's real body. At the end of that encounter, the Valkyrie's body, still possessed by Norriss' mind, was consigned to Niffleheim, the realm inhabited by the spirits of the non-heroic Asgardian dead, while Brunnhilde's mind in Norris' transformed body accompanied the Defenders, who had made the other dimensional journey with her, back to Earth.

For reasons yet unknown, Brunnhilde was not concerned at this time about reuniting her mind with her true body. It was not until Barbara Norriss' body was murdered that the Valkyrie's spirit and mind were inadvertently freed from their mortal host. With the help of Doctor Strange's magic, Brunnhilde regained her true body, which was rescued from Niffleheim by the Enchantress. Back in her real body, Brunnhilde regained her full memory and normal warrior personality as well. Brunnhilde then battled Amora and banished her to the crystal of souls. Feeling estranged from Asgard in general and Odin in particular for their neglect of her centuries-long plight, Brunnhilde chose to return to Earth with the Defenders.

Odin placed the dangerously powerful self-styled goddess Moondragon into Brunnhilde's charge. Brunnhilde was to teach Moondragon humility, and Moondragon served alongside Brunnhilde in the Defenders. Brunnhilde was to take action against Moondragon should she again become a menace. Eventually Moondragon reformed, but later she fell once again under the malevolent influence of the alien entity called the Dragon of the Moon. Moondragon attacked the Defenders, but Brunnhilde, given temporary additional powers by Odin for this occasion, including the power to grow to gigantic stature, opposed her. Brunnhilde summoned other Valkyries to her aid and together with two other Defenders, Angel and Cloud, they defeated Moondragon but failed to capture her.

Months later Moondragon returned to attack the Defenders. During this encounter, her power was vastly augmented by the alien Beyonder. In order to defeat the Dragon, Brunnhilde and the Eternal called Interloper projected their immortal life forces against it. They were joined by Defenders member Andromeda and the Defenders' former foe Manslaughter, for it was necessary that Brunnhilde's and Interloper's life forces pass through "mortal instruments" in order that Moondragon be defeated as well. Joining hands, the four allies hurled the tremendous power of their combined life forces at the Dragon, Moondragon, and Gargoyle, whose body was now under the Dragon's control. Three other Defenders went to rescue endangered innocents, and when they returned, Brunnhilde, Interloper, Andromeda, Manslaughter, Moondragon, and Gargoyle had all seemingly been transformed into statues of ashes and dust, and the Dragon of the Moon was apparently gone.

Brunnhilde was restored to life by Doctor Strange, now in the host body of a woman known as Sian Bowen. The other Defenders, Interloper, Andromeda, and Manslaughter were restored to life as well and they formed the Dragon Circle to battle the Dragon of the Moon. After the Dragon of the Moon was defeated, Brunnhilde returned to Asgard. Brunnhilde was killed in battle just before Loki's destruction of Asgard.

With the return of the Asgardians to Earth, Brunnhilde was next seen as a member of the Secret Avengers. Writer Ed Brubaker confirmed that the Valkyrie on the team was the original Brunnhilde.
