Fenrir was a member of one of the most powerful and richest families in Asgard. One day, when he and his family went hunting, they were attacked by a bear. Helped by wolves and abandoned by humans, he started to live with wolves adopting their life style and deeply hating humans. Later, he was chosen by Hilda as the Epsilon God Warrior. He died fighting against Shiryū when an avalanche fell over him and his wolves. His God Robe resembles that of his namesake Fenrir, the wolf child of Loki prophesized to bring about Ragnarök.
