The Super-Torpedo was a weapon created by Astronema with the intent of destroying Earth, an act that would allow her to rule the entire Universe. There were only two super-torpedoes ever created that were installed onto a Velocifighter.
Darkonda, betraying Astronema, took the fighter and flew off from the Dark Fortress. With the first missile, he fired at Dark Spector who spoke to Astronema at the time. She watched in horror as her master glowed with fire as he died. Now that Dark Spector was destroyed, Darkonda would use the second missile to destroy the Dark Fortress and Astronema with it.
But with his remaining strength, Dark Spector rose and intercepted the missile, which barley harmed him at the time. He swallowed Darkonda and exploded.
