Fenrir, also known as Fenris, Vánagandr or Fenrisulfr, is a giant wolf appearing in Norse mythology and one of three children of Loki and Angrboda. His mouth can open so large that it can envelop the heavens and the earth.
At birth, Fenrir had no particular powers at all and was not placed under the watch of the Aesir. But as time passed, his power grew. Fearing Fenrir’s strength and believing that only evil could be expected of him, the gods planned to bind Fenrir. At last, the gods attempted to bind Fenrir with a chain called Loedingr, but Fenrir easily bit through the chain. The gods then tried again with Dromi, twice as strong as Loedingr, but again Fenrir easily broke it. Finally, the gods asked the dwarves to forge a third chain, Gleipnir, and with this they succeeded in binding Fenrir.
He was prophesied to kill Odin during Ragnarok, so Odin bound Fenrir to his throne. When Ragnarok begins, he will be released, the ground will open and Fenrir will break free from Gleipnir and and then kill Odin in revenge for his imprisonment.
"Origin: Scandinavia. A giant wolf appearing in Norse mythology. His other name is Fenrisulfr, one of three children of Loki and Angraboda. His mouth can open so large that it can envelop the heavens and the earth. It's prophesized that he will eventually swallow the sun, and so he was bound. When Ragnarok begins, he will be released, the gorund will open, and he will eat Odin."

Shin Megami Tensei IMAGINE[]
"A gigantic beast of Norse mythology that swallows all. He takes the form of a wolf so big that when he opens his mouth, his jaws touch the earth and the sky. Blazing flames erupt from his eyes and nose. He was counted along with the world serpent Jormungandr and the goddess Hel as one of the three children of Loki, the god who would later trigger Ragnarok, and the giantess Angraboda. At birth, Fenrir had no particular powers at all and was not placed under the watch of the Aesir. But as time passed, his power grew. At last, the gods attempted to bind Fenrir with a chain called Loedingr, but Fenrir easily bit through the chain. The gods then tried again with Dromi, twice as strong as Loedingr, but again Fenrir easily broke it. Finally, the gods asked the dwarves to forge a third chain, Gleipnir ("entangling one"), and with this they succeeded in binding Fenrir. At Ragnarok, Fenrir will break free from Gleipnir and swallow Odin, the chief of the gods."
