Fenris was a giant Asgardian Wolf who served Hela during the times of the expansion of Asgard around the Nine Realms. Millennia after her death, Fenris was resurrected by Hela with the Eternal Flame and put at her service during her rule over Asgard. Fenris later fell into the vastness of space during her battle with Hulk.
Conquering the Realms
Following her death, Fenris' corpse was buried deep beneath Odin's Vault along with the corpses of the fallen Berserkers, and remained there for centuries as the beast's very existence was wiped out of Asgard's history by Odin. Nevertheless, when Fenris' mistress Hela returned from her banishment following Odin's death, she used the power of the Eternal Flame to reanimate Fenris as well as the Berserkers. Unlike them, Fenris was fully resurrected, and would later be used as a means of intimidating the Asgardians when Hela and Skurge went in search of the stolen sword Hofund.
As Heimdall guided the surviving populace towards his observatory, he spotted Fenris and an army of Berserkers guarding it from a distance. Fenris begins to charge towards the Asgardians before Valkyrie shot at her from the Commodore, but the gun had no effect on the giant wolf. At this point, Fenris resumed charging towards the Asgardians. Just as she was about to attack, Bruce Banner hit the bridge in front of her. Fenris paused and curiously sniffed at Banner's unmoving body to see if he is dead or alive. Deciding he was no threat, Fenris prepared to attack again, but was suddenly dragged back by her tail and thrown away.
Fenris is confronted by Hulk and engages him in battle before charging at him where she attempted to devour him, but it only succeeded in tossing them both into the river below. Later, Fenris is seen leaping towards Hulk trying to devour him again, but Hulk keeps her massive jaws open. Eventually, she snatches Hulk in her jaws, throttles him around like a chew toy and dunks him in the water, where she bites painfully into his highly impervious skin with her razor sharp fangs. However, Hulk punches Fenris off, sending the giant wolf falling to her death down the waterfall and into the void below.
Powers and Abilities
Asgardian Wolf Physiology: Fenris, as an Asgardian Wolf, and the personal pet and steed of the Goddess of Death Hela, is one of the most powerful and fearsome beings in the Nine Realms, to the point that even Heimdall showed visible signs of fear when cornered by the beast on the Rainbow Bridge, only preparing to face it once he knew it was absolutely necessary.
- Superhuman Strength: Fenris has tremendous strength that can match that of Hulk, which allowed her to engage the latter in a brief, albeit vicious battle. Fenris' jaw strength allowed her to bite through Hulk's durable flesh, causing Hulk to bleed, as well as to lift and throttle him around like a chew toy in her mouth.
- Superhuman Durability: Fenris is highly invulnerable, as she was unscathed after getting shot at by the Commodore, and even after fighting Hulk.
- Asgardians - Former Allies
- Sleipnir - Former Ally
- Loki †
- Surtur †
- In the comics, the Fenris Wolf is a creature of Asgardian origin, and is said to be the offspring of Loki and the giantess Angrboda, and the sibling of Hela and Jormungandr. Fenris is based on the Norse wolf god Fenrir, which was destined to kill Odin during Ragnarök.
- The Marvel Cinematic Universe's version of Fenris is a female, unlike her mythological counterpart (which is a male) and her comic book counterpart (which is gender-fluid).
- Fenris and Abomination are the only characters in the Marvel Cinematic Universe to have pierced Hulk's tough skin.
