Fenrir

Past Timeline
Being the son of the Wolf clan's head, he has been born with great power since his birth. Fenrir was in a human form until he reached adolescence and starting becoming more wolf-like. He had to wear a muzzle to prevent his instincts of devouring anything in his way. As an adult, he follows the clan tradition to follow the path of the moon.

He later became known as heroic among the other clan members due to his skills. When his parents died and the Wolves' territory was destroyed by the Celestial Guardians, he vowed revenge and met the Seven Demon Lords who were in the same situation as him, he joined them and treated them like brothers. He later overcame his instincts to eat anything but kept the muzzle to remind himself of his fallen territory and dead relatives.

With his six brothers his fangs struck the Tower of Heaven. He won many fights but eventually was defeated and sealed in the war against Celestial Guardians, he was sealed in his baby wolf form.

Season 4
Reginleif sneaks into Freyja's room and steals the Liberator's dagger. She planned to use the special dagger to unseal Fenrir from his form. Reginleif did not agree with Freyja's ideals and felt pity for Fenrir who just wanted to help his teammates. Fenrir was shocked that a Valkyrie would awaken him from his seal and Reginleif put him to rest before he could ask her more questions.

Along with Sun, Fenrir helped reunite and unseal the remaining brothers to attack the Valkyries once again, Surtr woke from his long seal when he witnessed Fenrir getting attacked by Trude.
