Bardulf is of an extraordinarily large size (much like Ula), leading the belief that he is either full-blooded or half dire wolf. He has dark fur, and a scar on his face from battle.
Bardulf is a very courageous wolf. He is also the strict one of the pack, and he is an alpha male. Bardulf is also a careful hunter and shows a more cautious approach at times, but will not hesitate to enter the fray to help protect Kotsu, whom he shares a close bond with. Bardulf occasionally barks at his yappier pups to stay quiet and patrols camp.
