"Looks like your doggy there would rather chew on you than us, Skull."
Bucky to Red Skull[src]

The Fenris Wolf is a giant wolf from Asgard.


He was seen with other of Asgard's warriors and creatures held captive by Red Skull in a HYDRA science base where a portal to the Asgardian realms is located. He was intending to unleash them into the battlefield on the Allies and win World War II. But his plans were foiled by Captain America and Bucky aided by the Howling Commandos and freed the captive Asgardians who later went back to their respective realms after fighting their way out.
