A white dwarf, manipulated by a vengeful alien named Raven (Casey Kasem in a dual role), begins stealing various objects, and relocating them, including a two-seat bicycle belonging to Marvin (Frank Welker). Superman (Danny Dark) sent Raven to prison some years earlier, and now knows Raven is looking for revenge......
Here's "Menace of the White Dwarf":
This Raven, of course, was a 1-shot villain who never appeared in the comics, and won't be confused with the later, female Raven of the Teen Titans. Dark doubles as the judge who sentenced Raven to prison.
