Sergeant Problem is a combo of Riddler and Nuke.
Edward Simpson was born into a broken home. His mother was dead and his father was abusive. He soon developed an unhealthy affection for his abusive father in his life. Years later, Edward Simpson became the test subject of the Weapon Plus program, the super-soldier program that had created Soldier-El and would later transform Bronze Cat into a killing machine. The enhancing and conditioning process went awry, leaving Problem seriously deranged. He also worked for the Amalgam version of General Thunderbolt Ross as a quizmaster black-ops agent.
