Janus was a college student and science major alongside Reed Richards, possibly at State University. Janus became obsessed with finding a new source of energy. He learned of a source, Negative Energy (or the Nega-Power), and sought Reed's aid in harnessing it, but Reed refused, warning him of its inherent dangers. Janus continued his search and ultimately succeeded, but exposure to the Nega-Power caused him to split into two separate beings. The new form contained his repressed darker urges and, calling itself the Nega-Man, overpowered Janus and sought to harness the Nega-Power to become master of the world.
