Marilyn Manson clone/rip-off from the Starz channel television series Party Down episode "Jackal Onassis Backstage Party" (April 23, 2010) He's sold 8 million albums. His latest is Born Out of Satan's Anus. There are also posters in the background with Satan's Pillows, on it which may be another album.
Jackal is so sick of being sucked up to and fawned over that he switches identities with catering staff member Roman DeBeers (Martin Starr) so he can play at being a "real" person and ordinary bartender. This works because of Jackal's outrageous outfits and full-face makeup. Such a stock premise shouldn't work as well as it does, but it does.
Jackal's real name is Arnold Sherling. Played by Jimmi Simpson.
