Created by Ben Conrad, the Champion of the oppressed was the main character of an unfinished book whom the subcounscious mind of his writer materialized in a being pretty much similar to Superman but with methods far more directs and violents. Many of his actions ressembled the original exploits of the Golden age Superman.
Superman could stop the Champion when he confronted Conrad about their feelings about the loss sense of justice from the now sour writer and how new methods had to be reached to solve conflicts. Even if some the actions of the Champion were wronged, his motivation and ideal were in the right place.
His demise however would lead to the birth of the Hollow men.
