Death has appeared in every Discworld novel, with the exception of "The Wee Free Men" and "Snuff", and had a possible cameo at the end of "Johnny and the Dead" (the character was not identified, but spoke in unquoted small caps).

Characters that often appear with Death include his butler Albert; his granddaughter Susan Sto Helit; the Death of Rats, the part of Death in charge of gathering the souls of rodents; Quoth, a talking raven (a parody of Edgar Allan Poe's "The Raven", although it flat-out refuses to say "Nevermore"); and the Auditors of Reality, personifications of the orderly physical laws and the closest thing Death has to a nemesis. Death or Susan appear as the main characters in five Discworld novels. He also appears in the short stories "Death and What Comes Next", "Theatre of Cruelty" and "Turntables of the Night".
