Norman Power was the commander of a passenger spacecraft.
When the ship went off course, Jason was able to drag it into the Land of Fiction. Norman was one of the only survivors of the crash, and Jason turned him into the fictional superhero White Knight. When his sidekick Sparky died, he had Carol Pullen remove his superpowers. He later thought he had regained them and jumped out a window to fly. However, he was still powerless and he plummeted to his death. (PROSE: Conundrum)
