The Wolves appear in Wolves of the Calla, and are similar to the mechanical bear, Shardik. They appear to resemble the famous Fantastic Four villain, Doctor Doom, and use tiny golden grenades called "sneetches " (a homage to J.K. Rowling's Harry Potter) as well as energy-emitting swords that resemble lightsabers (a tribute to George Lucas' Star Wars films) . The Wolves, preparing to attack the Calla, are ultimately defeated by Roland Deschain and his ka-tet.
The Wolves work for the Crimson King, and are responsible for taking the children of the Calla and bring them back to Fedic so they can take the children's brain matter to feed the Breakers, leaving the children roont. The final time the Wolves came was their last, and there are no more left.
