Ben Lockwood

"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?"

- Ben Lockwood while being arrested

Professor Benjamin "Ben" Lockwood is the former host of The Lockdown and a former history professor at National City University. After his life was torn apart by consequences of alien attacks, he began working with Mercy and Otis Graves as the leader of the Children of Liberty, known as Agent Liberty, serving to exterminate all extraterrestrials and establish humans as the superior race on Earth. He was later appointed Director of the United States Bureau of Alien Affairs under president Baker, which soon became an official Cabinet department and the position was renamed the Secretary of Alien Affairs. Ben is also the son of the late Peter Lockwood, the husband of the late Lydia Lockwood and the father of George Lockwood. Ben and the rest of his organization are all unwittingly pawns of Lex Luthor in his schemes.

Early life
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.

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 to deal with Ben's stab wounds. Later, Ben also had bad luck when Lena denied any help for his father.

Ben's life got worse after the Daxamite invasion as his home was destroyed in a fight between a Daxamite and Martian Manhunter. As a result, he began showing more prejudice to his alien students, which cost him his job. He began giving flyers on how aliens were taking away everything from humans until the Worldkillers attempt to terraform Earth. He went to save his father from the steel factory, but to his horror, his father didn't want to be saved and could only watch as his factory crushed him in the end. He spoke at his father's funeral afterwards and was surprised to see that Lena had came to pay her respects. She wanted to help him and his family during their time of need, but he refused, stating that she chose the aliens over the humans and they are to blame for everything that was happening. She told him that if he chose this path of blaming people for everything that was happening to him, no good would come from it, but he refused to listen.

Becoming Agent Liberty
Ben soon met his friends outside his father's ruined steel factory and together, they set fire to the Nth Metal factory as revenge for putting their factory out of business. During the fire, a person came out gasping for air. At first, he wanted to help him as he thought he was human, but was actually an alien disguised as a human. Recognizing him as the same alien that shot him once and refusing to consider aliens as people, he beat him to death with a pipe. He began recruiting others to his organization dedicated to ridding the earth of aliens where he was contacted by a person named Mercy Graves. Ben was unaware that he was working with Lex Luthor and he is the one who sent Mercy and Otis Graves to recruit him. She told him that she and her brother Otis knew about his organization that they were hunting down aliens and the alien that he killed. At first, he thought they were going to arrest him, but they actually wanted to recruit him for their plans against the aliens. They gave him equipment that would be useful to him. To test him, they told him he had to kidnap and kill an alien named Fiona Byrne who was beginning a group that would protect aliens from humans.

After the plan to expose the president in her alien form worked, he stood behind Fiona ready to kill her. Before he did, he told her that he never sought conflict with aliens, but they left him with no choice. When she asked who he was, he merely responded he was an agent of liberty and stabbed her in the back. He soon watched on TV as Supergirl stopped a fight between two human groups: ones that supported aliens being on Earth and others that didn't. While watching, he knew she would be a problem for them, but Mercy revealed she had Kryptonite that could be used against her. He told her to be careful with it as they couldn't kill Supergirl yet as she would then become a symbol of hope, but she told him it was just insurance. He soon went to his followers giving a speech that they would take back Earth from the aliens and went back to Otis and Mercy to see what their next move is. After returning from his followers, he saw Otis and Mercy were going to kill the D.E.O agent that freed them. Although willing to kill aliens, he refused to kill his own human kind. Although Mercy said it was necessary so they could tie up loose ends and that Jensen was a nobody. He convinced her otherwise though as he not only released Mercy and her brother, but could also bring them back into the D.E.O.

Personality
As a civilian= "Well, history is extreme, truth is extreme.The classroom isn't a safe place where everyone gets to hear a fairy tale version of the facts. And if students can't handle perspectives that are different than their own, then I don't know. Maybe they don't belong here."

- Ben Lockwood

Ben was once a mild-mannered and open-minded man, whose views eventually turned to anti-alien sentiment due to multiple alien-related incidents that has befallen the Lockwood family. He also worried about his father as he tries many times to prove him wrong about aliens and was devastated when he died. As Agent Liberty= "Because we can come together and we can tear out this alien disease that threatens to poison our world, we can invite them to return to the planets that they came from and we can restore health and vitality and security to this country. And I, as your Agent of Liberty, will stand with you as we dare to put Earth first!"

- Agent Liberty

As Agent Liberty, Ben is a human patriot and nationalist, who seeks to empower his fellow humans, regardless of ethnicity or faith, to unite against their ungodly extraterrestrial immigrants. Ben has witnessed many tragedies befalling, not only his family, but also many humans due to extraterrestrial activities. This is further fueled by the media disapproval to help these humans or even L-Corp to help them in their times of crisis, causing many humans to be let go without jobs and homes.

With the United States government turning on it's human civilians in favor of extraterrestrial amnesty, Ben decided to help humanity by exposing extraterrestrials of the threats they really are. He was kind to his followers and not willing to kill humans as seen when he let Raymond Jensen go despite Mercy Graves wanting to kill him.

After becoming being granted the title United States Secretary of Alien Affairs by the the President, Ben becomes more arrogant and self-righteous willing to arrest any aliens for wrongful reasons and that he has the power to do. He also became obsessed with Nia Nal who he sees as a threat to his plans willing to break into the Daily Planet just to arrest regardless of the consequences, after his beloved wife, Lydia died, he becomes more unhinged and obsessed with revenge to the point that he abandoned his son, Georgie in his time and grieving and need. Even when he caught the alien who killed his wife, he wanted to arrest more innocent aliens, despite the fact they were not involved in his wife's death, proving how consumed in anger he has become. As J'onn J'onzz pointed out, he has become no different from the late Manchester Black. He ultimately proven to be caring for one but himself and will focus on aliens more than his own family; losing the trust and love of his son in the process.
