Appearance
Fenrir was usually takes and maintains the appearance of a young boy with silvery white hair which is still strong for an ordinary individual to engage with.

However, Fenrir could change his appearance like the Midgar Devil in the past by becoming a frail, elderly man with his hair turning white then his face was covered in deep wrinkles and his limbs turned to become emaciated, when he wanted to get serious or when he met a more dangerous enemy like Aurora or Shadow.

Despite his appearance, Fenrir's strength had increased so much that opponents against him were breaking out in cold sweats from the intense pressure of his strength and the weight of his oppressive aura.

Personality
Fenrir was a former assassin who took pride in being a murderer, claiming to have killed countless people to reach the "pinnacle of martial prowess".

Overall, like many of the cult's higher-ranking members, Fenrir was a delusional psychopath completely convinced of his own invincibility.

Fenrir loves fighting strong opponents, as he gets excited at the prospect of fighting Zeta & Shadow after hearing their prowess and loves the thrill of fighting Aurora (in Claire's body) and is finally ecstatic when "Suzuki" fights him and reveals himself as Shadow.

At some point, Fenrir joins the Cult of Diablos and becomes the 5th seat Knight of Rounds, also Fenrir and his faction are controlling the Midgar Kingdom's underworld from the shadows for a long time. Every year, he takes a drop of "Tears of Diablos" to maintain his strength and immortality. Fenrir and his faction had been engaged with Loki's Sect faction for a long time.

But he had never acknowledged Petos' position as his equal and stated that his promotion was nothing more than a substitute, as normally he wouldn't be able to become a Rounds because his achievements are weak.
