Benjamin Lockwood once worked for the CIA but ultimately left in disgust at their methods and the types of missions he was being asked to undertake. He became so disenchanted with the Federal Government as a whole that he joined the paramilitary group called the Sons of Liberty, who outfitted him with the outfit and equipment to become Agent Liberty. As Agent Liberty, Lockwood helped to forward the Sons' cause of overturning the governmental regime which brought him into conflict with Superman, though he later briefly assisted the Justice League in battling Brainiac in the crossover Panic in the Sky. However, when the Sons asked him to assassinate politician Pete Ross, Lockwood refused and helped to bring down the group by sending vital information to reporter Clark Kent. Lockwood later learns that one of the founders of the Sons of Liberty was his former CIA mentor, and he became so disgusted with this revelation that he burned his Agent Liberty costume, vowing to never adopt the persona again. However, Lockwood subsequently becomes one of the many unwillingly brainwashed victims of a cult started by Brainiac and takes up the Agent Liberty identity once more. Agent Liberty and the other kidnapped meta-humans are rescued by Huntress and Vixen. Later, during the Earth-shaking crisis of Infinite Crisis, Agent Liberty is seen at a mass for fallen and missing superheroes. .|thumb|left Dozens of heroes, Agent Liberty included, also gather to defend the city ofMetropolis from the Secret Society of Super-Villains.

In other media
portrays a loose adaptation of Agent Liberty on Supergirl, set within The CW's live-actionArrowverse. Introduced as the "ruthless and terrifying" villain of the fourth season, this version of the character is depicted as "a brilliant orator in the guise of a family man" who has "eerie abilities of persuasion and manipulation". Benjamin "Ben" Lockwood was once a mild-mannered college history professor who only became an anti-alien activist after losing his home and father Peter during the Daxamiteinvasion and Reign's terraforming of Earth, respectively. Upon being fired by the university for his anti-alien opinions, Ben was approached by Lex Luthor's subordinates, Mercy and Otis Graves, who gave him the gear to become a self-proclaimed "Agent of Liberty". As Agent Liberty, Ben founds the Children of Liberty, a human-supremacist group that supports a human-first world order, to rid National City of all alien life whilst keeping these activities a secret from his wife Lydia and son George. He later defeats reporter Kara Danvers, Supergirl's secret civilian identity, during an alien debate on national television, prompting the network to offer him his very own weekly show named "The Lockdown". Ben is arrested after Supergirl learns of Agent Liberty's true identity with the help of the DEO, and a large crowd of human rights activists led by Lydia then rallies outside National City Men's Central Jail to protest his imprisonment. Ben is given a full pardon by President Baker, who answers to Lex, on the technicality that all of his victims were aliens rather than humans. He is promoted by Baker as the Director of Alien Affairs for the US government and repeals the Alien Amnesty Act. After poses as Supergirl and attacks the White House at Lex's request, Baker enforces martial law and deputizes Ben's Children of Liberty, giving them access to weapons from the DEO to begin rounding up aliens on the streets. Ben later injects himself with Lena Luthor's experimental "Harun-El" serum and gains superhuman abilities to avenge Lydia's death at the hands of one such alien. Upon learning that Lex was the one who orchestrated his rise within the government, Ben kills Otis and attacks Luthor's base of operations on Shelley Island with his Children of Liberty, only to encounter Supergirl's team instead. In the ensuing battle, Ben is cured of the Harun-El by James Olsen, thus stripping him of his powers before he and his men are arrested by Alex Danvers. While incarcerated, Ben is enraged to see George blaming him for Lydia's murder and denouncing his anti-alien campaign on national television. In the fifth season episode "It's a Super Life", Mister Mxyzptlk presents an alternate reality in which Ben's family died jumping off a building thinking that Supergirl would save them only for her not to show up. This led to Ben becoming Agent Liberty to abduct Lena and Thomas Coville with Otis' help in order to coerce Supergirl into revealing her identity.
