Agent Liberty (Supergirl)

"Look at my face. Look what they did to me. Now, I wore that mask to protect me and my family because there are aliens who don't like to hear what I believe, don't like to hear the truth, so I'm cards up. What about Supergirl, huh? You know who I am. Who is she?"

- Agent Liberty

Benjamin "Ben" Lockwood, also known as Agent Liberty, is the main antagonist of the fourth season of Supergirl. He is the leader of the Children of Liberty, a vastly growing anti-alien extremist organisation bent on sabotaging the Alien Amnesty Act and getting rid of every alien in America.

He is portrayed by Sam Witwer, who previously portrayed Davis Bloome / Doomsday in Smallville.

Biography
Ben was a history professor at National City University, living with his wife Lydia, his son George, and his father Peter. He had helped his father out at his steel factory for some time, even negotiating with Lena Luthor for help with the factory.

He founded the Children of Liberty, mostly comprising of the remnants of Project Cadmus. He employed Mercy and Otis Graves to act as his proxy, and steal an EMP from an alien scientist. His father Peter Lockwood is the main reason what started the anti-alien movement. At dinner with his family, the news showed Supergirl trying to snap the city out of Myriad, but Peter didn't approve of Supergirl and the Alien Amnesty Act, hating so much of aliens that he wouldn't accept material from them. Ben tried to convince him otherwise, but his father wouldn't have it.

However, after their argument, a fight at the Nth Metal Factory across the street included a fight between Peter's workers and two aliens at the factory, one of whom ended up accidentally shooting Ben in the chest. Supergirl arrived at the scene to break up the situation and Agent Alex Danvers helped deal with Ben's stab wounds. Later, Ben also had bad luck when Lena denied any help for his father. Ben Lockwood was finally arrested and exposed as the Agent of Liberty. After he was arrested, the people are against Supergirl and CatCo media in "Bunker Hill'.
