The wolf most associated with Norse tattoo comes via the giant wolf Fenrir.
Dictionary.com defines Fenrir as: “a wolflike monster, a son of Loki and Angerboda, chained by Gleipnir but destined to be released at Ragnarok to eat Odin and to be killed by Vidar.”
Most realism style interpretations of Norse wolf tattoos feature Fenrir, snarling and violent, either chained or breaking free from his shackles.
