Death (Discworld)

The Death of the Discworld universe is a tall figure in black.

Oh, and he is a skeleton who speaks in SMALL CAPITAL LETTERS. He made a brief appearance when Agents Suicide and Ithalond were following Sakhmet Black.

Death is occasionally brought into squickier romance fanfics, despite not being appropriate as a Love Interest at all.

Due to his nature as an Anthropomorphic Personification of an eternal concept, Death cannot be neuralyzed-- it is impossible for death itself to ever forget anything in the way a living being or a community of beings could. Despite this, Discworld's Death is very good about playing along with the idea of neuralization and not telling any canon characters about their unfortunate badfic escapades. It is likely that he knows about the PPC, but he seems to be a good sport about not telling anybody.
