What is "desaad"

DeSaad is a fictional comic book supervillain, appearing in books published by DC Comics. He is one of the followers of Darkseid from the planet of Apokolips in Jack Kirby's Fourth World meta-series.

As DeSaad serves as Darkseid's master torturer, his name refers to Marquis de Sade. At one point DeSaad had an assistant named Justeen, a reference to de Sade's novel Justine, although she bore little resemblance to the title character.
