Fenris

Fenris is a fictional animal featured in Norse mythology. It also appears in comic books published by Marvel Comics and is associated with the Thor line of comic book titles. Fenris is a mythological wolf creature from the kingdom of Asgard. He stands approximately fifteen feet tall and is believed to be the offspring of Loki Laufeyson (Ewwww). As such, some view Fenris as a Wolf God, while others see him as a Wolf Demon. Despite his animalistic traits, Fenris is actually very intelligent, and is capable of understanding human interaction making independent decisions based on practicality as well as natural instinct.

Fenris appeared in the 2017 feature film Thor: Ragnarok. He had died in battle ages ago, and his corpse was commemorated in a crypt far beneath the capital city. When Hela awoke, she used the Eternal Flame to resurrect Fenris and set him off to destroy members of the Asgardian resistance. Fenris battled against the Hulk atop of the Rainbow Bridge. This version of Fenris died when Thor Odinson released Surtur, thus instigating Ragnarok, which destroyed all of Asgard.
