Guardsman (comics)

Kevin O'Brien was born in Chicago. He became an engineer and inventor working for the newly opened Lakani Island plant of Stark Industries who came to the attention of Tony Stark when he invented a stun-ray that managed to harmlessly disperse a crowd of violent protestors. Tony invited Kevin to transfer to the main plant on Long Island, and he accepted. Despite a careless streak that once caused the laboratory he was working in to explode, he became a close friend of Tony and was soon appointed head of Stark Industries' research department.

On several occasions, Kevin assisted Tony and the supposed bodyguard Iron Man, notably against the Spymaster and the assistants the Espionage Elite, saving Tony's life on more than one occasion. Tony then decided to reveal to Kevin his secret identity of Iron Man, and to build for him a second suit of armor for use in the event of an emergency. That emergency would come a short time later, when Iron Man and girlfriend Marianne Rodgers were taken captive by the superhuman madman Mikas the Soulfather. Putting on the armor before being fully tested, Kevin fell prey to a malfunction in the cybernetic circuitry controlling the armor which apparently stimulated the regions of the brain where rage and jealousy originate.

Kevin found himself seized with sudden attraction for Marianne and became extremely jealous of Tony's power, looks, and fortune. At the same time, Simon Gilbert, then Chairman of the Board of Stark Industries' stockholders, grew alarmed that Tony was moving out of munitions production and mapped strategies with the board to seize controlling interest in the firm from Tony as principal stockholder. Clad in armor and calling himself the "Guardsman", Kevin offered to aid the board in their plot against Tony.[2] As a show of support, he agreed to quell a protest rally outside the plant. The Guardsman aimed his repulsor rays at the crowd, injuring four protestors. Sickened by what he did, Kevin turned on the renegade board members, physically assaulting them. However, seeing Tony with Marianne caused him to once again become unbalanced, and he went outside to vent his rage on the growing crowd of protestors. Tony donned the Iron Man armor and engaged the Guardsman in battle to prevent him from doing more damage. Losing, the Guardsman sought refuge in an experimental tank. In an attempt to stop him without hurting him, Iron Man's repulsor rays were trained on the vehicle and accidentally hit its fuel supply. The tank exploded, killing Kevin.[3]

Michael O'Brien was also born in Chicago, Illinois. Some months after Kevin's death, when the details of the incident came to public light, Michael, a sergeant in the New York City Police Department, decided that the official investigation exonerating Iron Man's actions was a cover-up. Reopening the investigation without official sanction, Detective O'Brien confronted Tony Stark, interrogated several employees, and declared his intention of proving Stark responsible for his brother's death.[4]

O'Brien finally hired Harry Key, an unscrupulous private investigator, to get him inside the Long Island plant. There O'Brien located the Guardsman armor and put it on, determined to use it to bring Iron Man to justice. However, the malfunction in the cybernetic circuitry that affected his brother's brain also affected Michael's brain, and he flew into a rage seeking to kill Iron Man. Iron Man confronted his attack and finally convinced him that the armor was causing him to act insanely. O'Brien collapsed on rebelling against his own urge to kill Iron Man. Stark took O'Brien into custody rather than press criminal charges, hoping to convince the man of his innocence in Kevin's death. While Stark worked on a new set of armor, the Japanese mutant Sunfire attacked the plant. Stark was unable to put on his new armor since it had not yet cooled, and unable to find any of his spare suits of armor since a saboteur had stolen them. Hence, he was forced to put on the Guardsman armor to fight off Sunfire. O'Brien witnessed Stark's heroic attempts to save lives over a video monitor, aware that Stark was risking a major heart attack by the strenuous activity. Escaping confinement, O'Brien decided he was wrong about Stark and determined to help him by donning the now-cooled Iron Man armor. Thus clad, he was mistaken for the real Iron Man and kidnapped by the Mandarin. Stark discovered an old set of Iron Man armor that the saboteur had overlooked and went to China to rescue O'Brien. Upon rescuing him, Stark chose to reveal his true identity to O'Brien before he went off to battle the Mandarin. O'Brien flew back to New York where he took custody of the Guardsman armor once more.[5]

After Iron Man defeated the Mandarin, Stark fixed the malfunction in the Guardsman armor's circuitry so it was safe to wear. Michael O'Brien was determined to use the armor to vindicate both his brother's and his own senseless actions. When Stark International was taken over by the criminal Midas, the Guardsman joined with a number of Stark's other friends and allies to battle Midas' men. He was turned to gold by Midas' power, but was later restored to flesh.[6] Having quit the police force, O'Brien interviewed for the position of security director at Project: Pegasus, the government energy research facility, after its previous director Quasar quit. With a high recommendation by Stark, O'Brien got the job.[7] Sometime later, while guarding the Project, O'Brien's Guardsman armor was damaged in a battle with the subhuman Lava Men.[7] It was later repaired at the Project's expense. O'Brien, as the Guardsman, has been living and working full-time in the Project since his appointment and has performed his duties capably.

Later, he was the security chief at Avengers Island.[8] He also participated in the Iron Legion against Ultimo, wearing a re-creation of the Silver Centurion armor.[9]

However, Stane escapes suspicion by claiming not to have had any knowledge of the Guardsmen's pasts.

In "Prison Break", the Guardsmen try to stop Zarda, Typhoid Mary, and the Crimson Widow from escaping the Vault. While the Guardsmen are quickly defeated, the Wasp and Captain Marvel manage to defeat the supervillains. The Guardsmen also make minor appearances in "Avengers No More" Pt. 1 and "The Vibranium Curtain" Pt. 2.
