The Dark Perkulators are a Forever Knight fan faction devoted to Nick's third-season partner, the human police detective, Tracy Vetter. However, unlike other "dark" fraction factions, they do not necessarily want the character to become a vampire. Rather, they recognize her to be a strong and capable police officer. As the introduction to the DP-L Yahoo Group puts it, "We see Tracy as a gal with attitude, dealing with difficult issues and giving as good as she gets."
