Despite whatever all his other characteristics may convey, Fenrir retains the air of a person that is confident, if not arrogant. Minor (and often, major) things in his body language - his walk, his stance, his expressions - reveal these feelings. At times, it seems he borders upon narcissism, especially judging from how much he enjoys his own company.

Fenrir has a legendary and virulent need for vengeance. Once crossed, he will make it his life’s work to ensure that whatever slight was received is repaid tenfold. This need for vengeance can be all-consuming, and can often lead to short-sighted decisions.

Killing has never been a problem for Fenrir; and he kind of enjoys it now, if he is honest. Killing's what Fenrir does, and he likes what he does.

While Fenrir does know both Basic and his native Shistavanen, he is unable to speak those languages due to his being brought up by wild animals in the jungles of Uvena. He understands what others are saying in the common tongue, but himself speaks only in sharp, measured growls that others cannot understand. However, he uses Telepathy frequently to convey thoughts, mental images, and opinions to others. Additionally, he sometimes walks on all fours, both in social and martial situations, just like a wild beast. However, sometimes it becomes impossible for others to understand with him, or pick up on his good intentions. Thus, he is still considered to be a predator.

Fenir has spent a considerable period of time of his life in the wilderness among wild animals. He prefers to use beasts to distract or outright harm his opponents in order to turn the whole environment against the enemy.

However, such a talent is not without downsides. Firstly, this is far more effective in case of a skirmish or isolated combat in the wilderness than in a battle. Secondly, this tactic leads to a reliance on being in the wilderness.

Fenrir is like a wild animal. He does not use any weapons. This gives him a disadvantage in any fight against those who do. However, Fenrir offsets this with his own slew of skills. He uses his large stature, brute strength, athletics, stealth, and stamina to stay clear of danger while wearing out his foe. This animalistic fighting makes him dangerous to his opponents, as well as allies who fight alongside him.
