Ljótólfr (= Ugly Wolf, title restriction) in his ulfhednar form, fighting against necromancy. In such a harsh and merciless moment, Ljótólfr has no other options but to attack with full power, in order to survive.

About the werewolf form: If my OC had to transform to a ferocious beast, it would have to be something like this. Not traditionally buffed, but quick and agile. He relies heavily on the power of his jaws, to tear off any threats in his way. Inspired by the concept of Ulfhednar, werewolves and tundra wolves.
Also, the werewolf has a beard. A bearded werewolf. Weee.
