Fenrir is a member of the Vali Team previously affiliated with Khaos Brigade. He is a wolf that possesses giant fangs that can kill a God, Satan, and even a legendary Dragon. He was created by Loki, making him the oldest brother of both Midgardsormr and Hel, as well as the father of Sköll and Hati.
Fenrir has the appearance of a giant wolf with ash grey fur, standing at about 10 meters tall. In Volume 11, his size has drastically decreased.
In the anime, Fenrir's fur was a greyish blue and he had two big yellow horns coming out of his shoulders.
Following his first appearance, Fenrir has been shown to be extremely loyal to his father and creator, Loki. After being subjugated and freed from Loki's control, Fenrir developed his own instinct, as well as gaining a strong attachment towards Le Fay Pendragon.
In the short-story "Wolf's Emblem", he was the narrative voice and it was shown that he possessed self-awareness and human-like intelligence, though his way of thought was different than a normal human's. Even more so, he has a stronger sense of pride, having very high standards and low tolerance for those who are incompetent. He also has his own view of hierarchy within the Vali Team, in which he ranks Kuroka and Bikou at the bottom.
Despite being known as the God-Devouring Wolf, the only Norse God he fears is Vidar.
Fenrir is one of the sons created by the Evil God, Loki, being his greatest masterpiece, as well as being the older brother of one of the Five Dragon Kings, Midgardsormr, known as the Midgard Serpent.
Fenrir is considered to be one of the most dangerous beasts having power that rivals the Two Heavenly Dragons, and is nicknamed the God-Devouring Wolf (神喰狼 Kamijiki Ōkami). At one point, he mated with a Giantess who was transformed into a wolf by his father and had 2 sons: Sköll and Hati.
