Guardian (James Jacob "Jim" Harper and Mal Duncan) are DC Comics superheroes introduced in April 1942 by writer/artist Joe Simon and artist Jack Kirby.

Guardian resembles the earlier Kirby and Simon character Captain America (first published 13 months earlier by Marvel Comics), as he had no super powers and carried an indestructible shield. When Kirby returned to DC in 1970, he eventually re-established the character as a supporting one in the Superman franchise: as a 'clone of Jim Harper who was head of security for Project Cadmus.

In the Arrowverse series Supergirl, James Olsen, portrayed by Mehcad Brooks, became the superhero Guardian. Additionally, James Harper appeared in the first season as a marine colonel portrayed by Eddie McClintock. In the sixth season, James Olsen’s sister Kelly Olsen became known as the Golden Guardian, portrayed by Azie Tesfai.

Publication history

He first appeared in Star-Spangled Comics #7 (April 1942) and was created by Jack Kirby and Joe Simon.[1][2]

Fictional character biography

Jim Harper

Guardian (Jim Harper) and the Newsboy Legion's debut. Cover of Star-Spangled Comics vol. 1, 7 (April 1942 DC Comics), art by Jack Kirby, Joe Simon

Jim Harper is a police officer in Metropolis' Suicide Slum who becomes a vigilante to catch crooks that the law could not prosecute, describing himself as guarding society from criminals.[3] He was trained to fighting condition by ex-boxer Joe Morgan (the same man who trained two other mystery men, Wildcat and the first Atom). He doesn't have superpowers, but he carries a bulletproof shield.[4]

He's aided by a group of boys known as the Newsboy Legion, to whom he is, literally, a guardian, having volunteered to take them in rather than allowing them to be sent to prison; he does so on the grounds that they're basically good kids who just needed a chance.[5] The Legion grows up to become the heads of the Cadmus Project, subsequently saving Harper's life by transferring his mind from his old, dying body into a younger clone of himself.[1]

It's later revealed that Jim Harper is the great-uncle of Roy Harper, who becomes Green Arrow's sidekick under the name of "Speedy".[6]

Other relatives include his niece Roberta "Famous Bobby" Harper, who is briefly a member of the second Newsboy Legion[7] and Jamie Harper, his grandniece working for the Gotham City Police Department. She works as Robin's personal contact in the GCPD, similar to the role Commissioner James Gordon plays for Batman.[8] After helping Robin and Jason Bard expose two dirty cops in the GCPD, Jamie Harper is promoted to Detective Specialist and transfers to the Metropolis Science Police.[9]

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.[10]

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.[11]

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.[12] 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.[13] 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.[14] 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 event reveals that Harper has a grandniece, Jamie,[15] formerly a detective of Gotham City Police Department and an associate of Robin III.

The Guardian later travels to the JLA Watchtower to warn the Justice League after finding a teleportation device in Metropolis. While on the Watchtower, the heroes are attacked by Prometheus, who blinds the Guardian. In the aftermath of the attack, Guardian and Mon-El are recruited by Kimiyo Hoshi to join the Justice League.[16] On his first and only mission with the team, the Guardian helps battle Doctor Impossible's gang of villains. After a mere three issues, the Guardian was written out of the book due to writer James Robinson's desire to work with a smaller cast.[17]

Following the events of War of the Supermen, Harper abandons his role as the Guardian and takes Jamie (now pregnant with Mon-El's child) off to an unknown destination.[18]

Mal Duncan

Main article: Mal Duncan

In Teen Titans #44 (November 1976), the previously uncostumed Titan Mal Duncan takes the name of the Guardian, wearing the original's outfit and an exoskeleton with strength augmenting abilities. The two Guardians finally meet in Superman Family #s 191-193 (Sept 78-Feb 79), when Mal helps rescue the Harper clone from Adam, an evil clone created using genetic material from both Harper and Dubbilex who have taken control of the DNA Project.

The Crisis on Infinite Earths removes Duncan's career as the Guardian, although he does appear briefly in his Guardian costume during the Crisis itself.

Jake Jordan

Main article: Manhattan Guardian

In 2005, Grant Morrison's Seven Soldiers megaseries introduced a new character based on the original Guardian, Jake Jordan the Manhattan Guardian.

Powers and abilities

The Guardian possesses exceptional combat and tactical skills. He was trained in many forms of fighting, and excelled at gymnastics, thinking quickly on his feet, and deduction. His only weapons are his golden helmet and shield. Guardian often used a customized motorcycle equipped with autopilot and a set of video cameras filming from various angles and recorded on videodisc.

The Harper clone possesses enhanced strength and reflexes, and an accelerated healing factor. The Harper clone's exact strength level is unknown but has demonstrated the ability to hurt Superboy (who he trained in hand-to-hand combat) and Kryptonians from Kandor. As an agent of Cadmus, Jim Harper also has access to the wondrous Whiz Wagon. The Hairies (a super-advanced tribe of techno-wizards, originally genetic creations of Donovan, who left Cadmus) built the Whiz Wagon to handle every situation. It can adapt to every terrain, fly, and even go underwater. The Wagon can be remote controlled or pre-programmed and is equipped with a set of powerful weapons and various gadgets.
