|“||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 one of the main antagonists of Season 4 of Supergirl. He is the leader of the Children of Liberty, a vastly growing anti-alien extremist organization bent on sabotaging the Alien Amnesty Act and getting rid of every alien in America.
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 steal an EMP from an alien scientist. His father is the main reason he 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 wounds. Later, Ben had bad luck when Lena denied any help for his father.
Ben 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".
In the second half of the fourth season, President Baker is anti-alien and also a supporter of Ben Lockwood. He found a loophole to grant his pardon. The President appointed him Director of Alien Affairs. So he and the rest of the children of liberty gets to finish repealing the Alien Amnesty Act. In All About Eve, the Alien Amnesty Act was officially repealed. He is unaware that he and the Children of Liberty are all patsy's aka pawns of Lex Luthor. In the end of Lex Luthor's tyranny, Lex Luthor is dead and President Baker is impeached. The Alien Amnesty Act is reinstated and Ben is back in prison and his son is now an alien supporter. Ben was not only trapped in his own father's hate and in the end he end up back in jail, but his misguided anti-alien crusade lead to his son hating him thus becoming estranged from him.
