Morgu
The "executioner's planet", a world where Superman is deposited by The Anti-Superman Gang after they de-activate his powers by dusting his costume with Red Kryptonite. Superman relies on his heroic nature, improvising intelligence, and fighting spirit to win over the hearts of the planet's slaves under the name of "Supro", a long-expected deliverer from their bondage. (S No. 229, Aug 1970: "The Ex-Superman!")
