Here is Wolfgang protecting his children Lucky Clover and Wolfborne.
Based on what Aura-Paws said, Wolfgang can be a protective father. when he sees his cubs in danger, he'll go in a feral state and do everything he can to save and protect them. So if you mess with his kids, it'll be the last think you may ever do.
This happened when Clover and Wolfborne were young, the young werewolf explored far off in the forest, in which his sister tried to convinced him that his mother Tuff Luck told him not to get lost, but he claims he can take care of himself, but suddenly, the most dangerous and violent of the Chompies called the Snapping Chompies started attacking them.
They ran off to the cave to hide, but the Chompies followed, one of them bit Clover on the leg, which she cried in pain. Suddenly Wolfgang came to their rescue, and he suddenly went into a feral state when he saw them in danger, as he started killing the Snapping Chompies, while the other Chompies ran off, Wolfgang then saw the blood on his hands and teeth, which got him in disbelief, which is something he had never done before in his life, though normally he uses his Bone Harp and music for battles, he then hugged his children, who are crying, as he took them home.
