Golden Guardian In Superman's Pal Jimmy Olsen #135 (January 1971), Jack Kirby reintroduces the boys of the now grown-up Newsboy Legion as supporting characters connected with the DNA Project (later Project Cadmus), a genetics research laboratory. One of the Project's experiments is a clone of the late Jim Harper, who takes up his predecessor's role, and becomes the Project's Head of Security as the Golden Guardian. Post-Crisis this character is simply known as the Guardian. Harper remains Cadmus' Head of Security even after the former Newsboys leave. Eventually, he too is killed, although another clone is created and rapidly aged to adulthood, retaining all his predecessor's memories. This Guardian disappears along with the rest of Cadmus following an altercation with Amanda Waller and President Luthor, and his whereabouts are unknown. Post-Infinite Crisis Following Infinite Crisis, the Guardian clone's backstory was retconned. As Dubbilex explains to Jimmy Olsen, Jim Harper was not killed in the line of duty, but shot by Cadmus' first head of security, Jonathan Drew, upon discovering the clone was already being created. It's also revealed that the original Guardian clone had left Cadmus early on, and was now living in the town of Warpath on the Mexican border, where he assisted Sheriff Greg Saunders. Subsequent appearances of the Guardian had been new clones, each of which died within a year. The original Guardian clone has decided to move to Metropolis with Gwen, his adopted daughter (in fact, an adolescent female clone of himself that he rescued), during the New Krypton storyline. Science Police team leaders DuBarry and Daniels, along with several prison guards, are killed during the events of New Krypton when a team of Kandorians led by Commander Gor assault Stryker's Island and demand custody of Parasite. The Science Police Control 'Rachel' tasks Guardian to act as a liaison between the Metropolis Police Department and a coalition of superheroes in bringing justice for the fallen science police officers and prison guards. After the Kandorians leave Earth, Guardian is appointed Field Commander of the Science Police, as replacement for DuBarry and Daniels, due in part to his cloned memories of Jim Harper as a police officer and Guardian as a superhero. He is asked by Superman to help Mon-El, offering him a job with the Science Police and mentoring him on how to be a hero. The issues of Detective Comics published during the One Year Later
