After Superman finishes an experiment with radioactive materials, a lab assistant, Jensen, is assigned to dispose of them. Jensen opens the container and is irradiated by atomic particles. He soon discovers that though disfigured he can drain energy from people.
Jensen plans to use his new powers for crime by stealing the power of Superman. He visits a construction site where the Man of Steel is scheduled to attend and begins draining Superman's energy. In so doing, Parasite discovers Superman's secret identity. Despite Superman's efforts to fight the Parasite he continues to grow weaker.
