Marvin McNasty

Marvin McNasty is the main antagonist of Pound Puppies and the Legend of Big Paw who is the descendant of Sir McNasty. He has two stupid henchmen named Lumpy and Bones, who usually goof up McNasty's schemes. Marvin is allergic to cats. He stole half of the bone of scone and invented the Mean Machine to turn puppies into vicious guard dogs. Ironically, at the end of the movie, after the bone of scone was back together, he and his henchmen were reformed by his own machine and helps Tammy and Jeff at the adoption bazaar. Marvin and Sir McNasty were voiced by George Rose, while Lumpy and Bones were voiced by Wayne Scherzer and Frank Welker respectively.
