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. At one point, he mated with a Giantess who was transformed into a wolf by his father and had 2 sons: Sköll and Hati.

Powers & Abilities

God-Killing Fangs: Fenrir's strongest attribute is his immensely powerful fangs that are said to be able to kill even the most powerful beings, including Gods.

Claws: In addition to his fangs, Fenrir's claws are just as powerful, and are capable of dealing damage to Gods. As such, these claws can pierce through the defenses of Dragons, such as a Scale Mail wearer and the former Dragon King and Ultimate-Class Devil, Tannin.

Immense Strength: Fenrir is regarded as even far more dangerous than his father Loki, an Evil God, and is considered on par with the Heavenly Dragons before they were sealed. He was able to easily overpower Tannin, a former Dragon King, and even Vali in his Juggernaut Drive was unable to defeat him. In fact, before losing most of his power, he was among the "Top 10 Strongest Beings in the World", his power comparable or greater than Typhon, the "King of Monsters," with the Afterward of Volume 13 implying a position as the number 10 under normal conditions. During the match against "Team Rias Gremory", it is revealed that Fenrir can transform back into his larger form, in which he can use 80% of his original strength.

Immense Durability: Fenrir is extremely durable, able to fully take on the attacks of the Gremory Team, Vali Team, and Tannin with little to no injuries. Even after being bombarded by Rias Gremory in her Forbidden Invade Balor the Princess form, it was capable of continuing to fight against her without any problems despite his injuries.

Immense Speed: Fenrir is able to move at god-like speeds, making him extremely dangerous when attacking with his fangs and claws. He was capable of easily dodging Rias Gremory's and Gasper Vladi's attacks.

Enhanced Senses: Fenrir possesses incredible senses, as he can sense the expressions and emotions of his comrades in the Vali Team with incredible accuracy. He was able to detect Valerie Tepes, even though she was hidden in a building that allowed Fenrir and Gogmagog to retire her from the match.
