The Fenris Wolf first appeared in Marvel Comics in Journey into Mystery #114 (March 1965), and was adapted from Norse legends by Stan Lee and Jack Kirby.

[volume & issue needed] Just like Norse mythology, Odin had the Dwarfs forge the chain Gleipnir ("deceiver" or "entangler").

It appeared to be only a silken ribbon, but was made of six wondrous ingredients: the sound of a cat's footfall, the beard of a woman, the roots of a mountain, bear's sinews, fish's breath, and bird's spittle (which explains why these things are not found today).

[volume & issue needed] Hela at one time unchained the Fenris Wolf to bring about Ragnarok, only to be thwarted by Thor.

[3] Loki later unchained the Fenris Wolf to aid him, Ulik, and Hyrm in attacking Asgard, using weapons that were forged for them by Surtur.

[volume & issue needed] The Fenris Wolf assisted in the attack on Vanaheim and faced Thor again in battle.

Thor bound the Fenris Wolf in chains and used his body to knock down Durok in order to save Sif.

With Durok slain, the Fenris Wolf snapped his chains and fought Thor, only to be struck down by Beta Ray Bill.

Beta Ray Bill used the power of his hammer Stormbreaker upon the Fenris Wolf, reducing him to a skeleton as the monster's punishment for attacking a weakened Thor.

[volume & issue needed] The Fenris Wolf escapes from his prison, a place deep in the dimensional 'Hells' and steals a technological device that would slaughter innocents, humans and gods alike.
