Lt. Artie King is a police lieutenant, presumably in Washington, D.C. (since the Huntsman fights many of the same villains as Freakazoid). He is friends with the Huntsman, and is repeatedly stuck with the unpleasant task of telling the Huntsman that there is no crime anywhere. His precinct has the Horn of Urgency on its roof. He is constantly reading a newspaper, which obscures his face.
His voice is provided by Dorian Harewood. His name presumably refers to King Arthur.
