Ben Lockwood (Agent Liberty)

Within the Arrowverse television continuity (Supergirl, Season 4), Ben Lockwood is presented as a former history professor who becomes obsessed with anti-alien politics after personal grievance tied to his father's steel plant being shut down. He transforms that grievance into public activism and propaganda, adopting the Agent Liberty persona and founding or leading the Children of Liberty movement; this television portrayal adapts the Agent Liberty name from DC Comics into a human, political antagonist for the series.

Sources describe Lockwood as a human male, a former National City University history professor and the former host of a media program called The Lockdown; these occupational descriptors frame his public-facing appearance as professional and media-oriented. In the Arrowverse he also presents a public/political persona under the alias Agent Liberty and uses branding and militant imagery associated with that identity in his public activities. Fan and reference summaries do not provide a detailed folkloric costume description beyond his use of the Agent Liberty identity as a public brand.

No supernatural powers are attributed to Ben Lockwood in the cited sources. His effectiveness derives from rhetorical skill, media influence, organizational leadership, and political mobilization: he uses broadcasting (The Lockdown), political branding (Agent Liberty), and the Children of Liberty organization to recruit supporters, spread anti-alien propaganda, and provoke confrontations that draw in institutions and superheroes. His actions lead to criminal prosecution and large-scale social and political consequences within the narrative.
