An unnamed army brigadier, who looks and acts very similar to Lethbridge-Stewart, appears in the comic strip "Caballistics, Inc." He first appeared in the story "Going Underground", where he is in charge of the army's response following a demon invasion of the London Underground; a member of his SAS team refers to "bloody robot yetis" having been down there once. He shows up again in the story "Ashes", in charge of the military response to a devastating attack on Glasgow. This character is one of several references to both the "Doctor Who" universe and other sci-fi/horror properties in "Caballistics".
