Death (Discworld)
Death is a fictional character in Terry Pratchett's "Discworld" series and a parody of several other personifications of death. Like most Grim Reapers, he is a black-robed skeleton usually carrying a scythe. His jurisdiction is specifically the Discworld itself; he is only a part, or minion, of Azrael, the universal Death. He has been generally used by Pratchett to explore the problems of human existence, and has become more sympathetic throughout the series.
Death (DC Comics)
In "Captain Atom" #42 Death appears alongside Black Racer of the New Gods and Nekron (a being embodying the will of "The Black", the solitude and peace death represents from "Green Lantern"). The story stated that all three were equal, representing different aspects of death. Gaiman has denied this, however, and his stories make it clear that Death of the Endless is the ultimate personification of Death. It might be assumed, however, Nekron, the Racer, and the Black Flash are connected to her in some way. Alternatively, there may be multiple avatars or gods of Death in the DC universe, besides those claiming to be Death. Blackest Night has resolved this apparent contradiction or ambiguity, with Nekron no longer being referred to as an aspect of death but instead as a construct formed of darkness in response to the emerging light of the emotional spectrum.
