Rowlf is the story of a girl and her dog. In the fanciful kingdom of Canis there is a princess named Maryara who possesses a loyal pooch named Rowlf. Her father rules a poor land but nonetheless there are suitors for Maryara's hand. One such is Raymon who is less than a scrupulous fellow, and one Rowlf distrusts immediately.
Raymon takes Maryara and Rowlf to a sorcerer named Sortrum who is able to turn one animal into another. But Rowlf is suspicious, and he and Maryara soon leave so that she can bathe in a cool pool. But she is spied upon by a demon, part of a military unit on a mission of destruction and plunder.
She is kidnapped and Rowlf in desperation returns to the tower of Sortrum where in order to get the truth from him he is transformed into a creature both dog and man. Rowlf uses this new form to pursue Maryara's captors.
Rowlf catches up to the demon army and we are treated to the naive man-dog hero using their own tanks against them as he fights doggedly to save his mistress.
Rowlf originally appeared in the fanzine Voice of Comicdom and later was collected by the underground Rip Off Press.
To complete the trilogy Corben gave us The Spirit of the Beast, in which we encounter the son of the previous werewolf named John Wulv. He finds a woman being assaulted by three men and drives them off. Then she agrees to lock him up because of his dangerous change in the full moon's light. What happens then is quite a surprise. Both of these stories were reprinted in Heavy Metal in, though we get them in the original black and white format in this collection.
