Lucifer Samael Morningstar is a fictional character who appears in American comic books published by DC Comics. He is an adaptation of Lucifer—the Biblical fallen angel and devil of Christianity—and is one of the most powerful beings in the DC Universe. Though various versions of the Devil have been presented by DC Comics, this interpretation by Neil Gaiman debuted in "The Sandman" (vol. 2) #4 in 1989. Lucifer appears primarily as a supporting character in the "The Sandman" and as the protagonist of the spin-off "Lucifer".
