Carl Banks is a main character in the Frasier-based fan fiction spin-off Roz.
Carl is a suave and sophisticated man who refers to himself as the "love doctor" of KACL but is officially the agony uncle.
Carl is first seen in Roz at the beginning of Season 27. Carl initially appears somewhat demanding and expects to be treated like a movie star, but he quickly sees this attitude is unpopular and makes an effort to gain some friends. Eventually, he is accepted by Bob "Bulldog" Briscoe and the others as one of the guys. Early in Season 30, Carl departs the station to pursue a relationship with Fiona Floyd after a brief romance with her two years earlier.
