Agent Liberty (Supergirl)

"The universe is vast. They come from outer space. They take our jobs, our culture. They steal from us. They hurt us. Look what they've done to our city. Our country. Our world. A wave of destruction this planet has never seen. We don't need their heroes. When humans root out the invaders, we can be safe again. We need to stand up and be heard, because divide we fall. I am an agent of liberty."

- Agent Liberty

Benjamin "Ben" Lockwood, also known as Agent Liberty, is the main antagonist (or one of) 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 ridding every alien in America. He is potrayed by Sam Witwer, who previously potrayed Jason Teague / Doomsday in Smallville.

History
Though awful lot of Lockwood's backstory is unknown, it's said he didn't always hate aliens but grew to for unknown reasons.

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.
