Fenrir the great wolf

Alexander forssberg fenrir1

In Norse mythology, Fenrir (Fenrisúlfr) was this wolf that grew so big the gods got all nervous and decided to imprison him. Odin and the gang tricked him into some magical ropes and tied him down with a sword in his mouth.
Pretty messed up but prophecy says when Ragnarök comes around, Fenrir will break his bindings and take his revenge.
