In his youth, Thor, young stubborn, prideful and strong, was egged on by the words of his brother Loki, that he needs to prove himself by breaking the toughest beasts, that could no be broken. These beasts of course referring to the lords of the goats, Toothgnasher and Toothgrinder. Two mystical goats, that would not bend, nor bow, to any human, elf, troll of god. Thor tried and attempted to break either animal, but was met with failure, usually due to his source of bridle not being able to withstand the vigor required to the task of taming Toothgnasher and Toothgrinder. Seeking to resolve this, Thor enlisted the aid of expert dwarves to create the magical bridle the Bregd Thrall. With this new bridle Thor now had to deal with the issue, that neither Toothgnasher nor Toothgrinder would cede if there counter part was allowed to be unrestrained and so Thor in his naive ingenuity caught and broke both majestic goats at the same time. Thor riding his two need steads back to Asgard, Toothgnasher and Toothgrinder finally having a master.
The Marvel version of Toothgnasher was adapted by Steve Englehart, and John Buscema, inspired by the Norse mythological creature of the same name. It first appears alongside its constant companion Toothgrinder in Thor #339

In this reality where zombie nazis have taken over the earth thanks to Loki, the all father Odin is turned into a zombie, and as such even Toothgrinder and Toothgnasher are now zombies. Them seem to be the master plan behind the zombies scheme to travel across dimensions, as they have a ship attached to them. They are considerably larger in this reality, as they have feasted on the zombified Odin and as such inheriting much of his power. Even though as a general rule zombies can't and won't eat other zombies, as Toothgnasher and Toothgrinder are goats, they can and will eat anything.
