In the Redwall series, there are villains, also described as vermin, featured in every novel, of all different species (rats, foxes, ferrets, stoats, weasels, etc). This category lists all known villains, inclusive of those with a villainous species.

Brian Jacques said that his villains are reflections of the fear he experienced as a child during World War II "when the newsreels would come on, and we would see skeletal people in these awful pajamas behind the barbed wire, and this is what the Nazis did to them. I was under the seat." - New York Times (April 2, 2001)
