Malum Kranus, better known as Anti-Pops, is the main antagonist of the Cartoon Network series Regular Show.
He is the twin brother and archenemy of Pops Maellard and is a godlike embodiment of evil, who is so powerful that he is capable of destroying the universe. Anti-Pops seeks to kill his twin brother and wipe out the universe to recreate it in his own twisted image.
He was voiced by Robert Englund, who also played the Stag-Man in the same show, Freddy Krueger in the A Nightmare on Elm Street franchise, the Riddler in The Batman, Bill Gartley in The Mangler, and the title character in the 1989 film adaptation of The Phantom of the Opera.
