*These were the final episodes of the 1966 HannaBarbera Space Ghost cartoon series. Unlike the 1966 episodes that were standalone, the final 6 episodes that aired in 1968 formed one story arc, like a movie, where The Council of Doom (Zorak, Moltar, Brak, Spider Woman, Metallus, Creature King) join together to plot the death of Space Ghost.
*Spider Woman was originally Black Widow, but her name was changed to avoid confusion with Marvel's Black Widow. Coincidentally Marvel Comics went on to use the name Spider Woman about 9 years later, and Space Ghost's Spider Woman eventually went back to her original name in subsequent appearances.
*The Council of Doom predates DC Comics Legion of Doom by about a decade and is essentially the same exact concept.
*Many of the villains on the Council of Doom appeared to die in their last appearances, such as Brak, Metallus, & Creature King, but survived death without explanation.
*Episode Names: The Meeting / Clutches of Creature King / The Deadly Trap / The Molten Monsters of Moltar /Two Faces of Doom / The Final Encounter
