BEWARE OF SPOILERS!
The Children of Liberty
A radical anti-alien movement which started small but grew stronger after the numerous alien invasions Earth suffered in recent years.
- Darker and Edgier: They are even more extreme than Project Cadmus was. While Lillian Luthor's master plan was to deport all aliens from Earth, the Children of Liberty have much more deadly things in mind.
- Dirty Coward: They always attack in groups, but whenever somebody proves to be not an easy target for them, they tend to run away.
- Fantastic Racism: Goes without saying. Their usual moniker for any kind of aliens is "roaches", likening them to cockroaches in how they infiltrate society and then become impossible to get rid of.
- Humans Are the Real Monsters: Despite all their rhetoric and claims of helping people, the Children of Liberty are, almost without exception, shown to be worse than the aliens they attack (who are, more often than not, helpless and/or innocent).
- Mundanger: What makes them so scary is that most of their supporters are completely normal people.
- Not-So-Well-Intentioned Extremist: A number of their plans endanger humans, with at least one (a False Flag Operation to spread fear of aliens) directing targeting innocent people, exposing the group as nothing but xenophobic hate-mongers rather than the Well-Intentioned Extremists they claim to be.
- Putting on the Reich: Once they've been deputised by President Baker, they adopt a Neo-Nazi aesthetic, complete with armbands. Lockwood's own attire gives him a distinct resemblance to an SS officer.
- Right-Wing Militia Fanatic: They're a bunch of well-armed Malevolent Masked Men who use whatever weapons available to kill and stoke hatred against as many aliens as they can.
- Villain with Good Publicity: Especially after Baker deputizes them.
(Former) Director Benjamin "Ben" Lockwood / Agent Liberty
Species: Human note
Portrayed By: Sam Witwer
The head of the Children of Liberty. He is a former history professor who became a terrorist after a series of familial and personal tragedies which he blamed on aliens' presence on Earth. Originally just a charming demagogue, he is eventually appointed Director of Alien Affairs by an increasingly unhinged and corrupt President Baker, allowing him to take his beliefs in a direction he never dreamed of.
Eventually, all of his efforts are rendered moot by the revelation that he has been nothing but Lex Luthor's pawn all along.
- Absolute Xenophobe: A murderous fanatic who kills aliens just for being aliens.
- Adaptational Job Change: In the comics, he was a CIA agent before becoming Agent Liberty. Here, he's a former history professor.
- Adaptational Villainy: While Agent Liberty was a hero in the comics, this version of him is an Absolute Xenophobe who murders aliens.
- Adaptational Wimp: Agent Liberty in the comics was a CIA agent, is skilled at hand-to-hand combat, and possesses several gadgets to give him an edge. Here, he is borderline helpless in any physical confrontation.
- Ape Shall Never Kill Ape: He is appalled at the idea of killing humans despite being an advocate for alien extermination... when he's not using alien tech to frame human murders on them to stoke xenophobia. He's also willing to throw away any pretensions of solidarity with his fellow man when he feels personally aggrieved; Lockwood tried to kill Manchester Black as soon as his enemy was disabled and helpless, and later murders a Child of Liberty for trying to take over the organisation.
- Asskicking Equals Authority:
- Averted. He's only the head of the organization due to his charisma and has to leave the muscle to people like Jensen and the Graves siblings. When Manchester Black catches him flatfooted in his home, Ben is completely at his mercy.
- Played straight when some more rabid members begin to think he's gone soft and begin grumbling about changes in leadership... and he responds by killing said member with his mask. After that nobody dares challenge his authority.
- Played even more straight after he takes a dose of undiluted Harun-El.
- Arch-Enemy: Manchester Black despises Lockwood for murdering his fiancée, Fiona, setting off Manchester's crusade against the Children of Liberty and his formation of the Elite. Even when Manchester has other priorities or is pursuing other goals, Lockwood remains very high on his hit list.
- Bad Boss:
- Pressed for a new advantage in his crusade against aliens, Agent Liberty forcibly infects Jensen with Parasite, a painful experience that leaves Jensen in constant agony.
- Lockwood feels fine with using a Body Double to keep himself out of harm's way, showing little regard for said doubles' lives.
- When one member of the Children of Liberty decides that Lockwood has "gone soft" and tries to take over, Lockwood bashes the would-be usurper's head in, and threatens everyone else present to keep them in line.
- Big Bad: For Supergirl Season 4. In reality, Lex Luthor is the true Big Bad and Lockwood is just a pawn in Luthor's scheme.
- Big Bad Wannabe: At the end of the day, for all the threat he poses, Lockwood is nothing but a pawn in the schemes of Lex Luthor, the real Big Bad of Supergirl's fourth season. Compared to the super-genius who runs rings around the heroes and poses a grave threat to the likes of Superman and Supergirl, Lockwood is next to nothing.
- Blade Below the Shoulder: One of his gauntlets has a retractable blade, which he uses to kill Fiona.
- Boisterous Weakling: Ben's a very loud, confrontational person who never runs out of threats toward aliens, but he's barely an inconvenience combat-wise.
- Brought Down to Normal: Loses his unstable powers during the Season 4 finale again, being injected with the cure by James.
- Charm Person: Mercy provides support for him because he has the charisma to sway people against aliens unlike her other associates.
- Contrasting Sequel Antagonist: He is the first sole male Big Bad on Supergirl. note
- Corrupt Bureaucrat: When President Baker appoints him Director of Alien Affairs, he's gleefully abuses the position to advance his human supremacy agenda.
- Dirty Coward: Agent Liberty's primary victims are aliens who helpless, and he himself doesn't take part in the Children of Liberty's field operations, although part of that might be simple pragmatism; he's a former history professor, not a soldier or lifelong criminal.
- Even Evil Has Loved Ones: Despite his genocidal views against aliens, he is/was a loving family man. When Manchester arrives in Lockwood's home to confront him, Lockwood prioritises his wife's safety.
- Even Evil Has Standards:
- He rejects the idea of killing humans, talking Mercy out of murdering Agent Jensen.
- Even a rabid xenophobe like Lockwood wants nothing to do with Lex Luthor.
- Evil Teacher: He was a professor before becoming an anti alien fanatic and he was fired for using slurs against a former alien student of his.
- Fantastic Racism: His goal is to rid the world of aliens. Even before Jumping Off the Slippery Slope, he defended a xenophobic rant in his classroom by saying, with regard to aliens, that "they're not people", and as a wounded alien factory worker pleads for mercy, Lockwood bludgeons him to death with a hateful sneer.Floor manager: Please! I'm just a floor manager!
Lockwood: No... you're an alien. [beats the floor manager to death]
- Faux Affably Evil: A man of great intelligence and charisma, Agent Liberty sells himself as a heroic figure, urging people to rise up and defend their rights. In reality, he's a xenophobic hate-monger trying to turn people against aliens. This is in stark contrast to the genuine Nice Guy he used to be. The falseness of his affable demeanor is shown quite well at the end of "Parasite Lost"; while brooding over the failure of his latest plan, Lockwood gets a phone call and answers it angrily, only to suddenly switch to a friendly tone when he realises who he's talking to.
- To Supergirl. They're both symbols for their respective sides of the alien argument, both encourage others to stand up and follow what they believe is right, and both are close with their family. In all other ways, they're total opposites. Unlike the genuinely good-natured Kara, Lockwood is Faux Affably Evil, hiding his cruelty beneath his eloquence. Supergirl shows her face to the public (although not her identity), while Lockwood initially hides behind a mask. Kara is brave, superpowered, and a capable combatant, while Lockwood is a Dirty Coward, normal human, and has trouble handling himself in a fight. Kara encourages her sister to be the best version of herself, while Lockwood's influence builds up his son's bigotry. While Kara loses favor with President Baker, Lockwood finds himself in the man's inner circle. Supergirl champions hope, but Agent Liberty spreads fear.
- To Manchester Black. Both are humans driven to violence and hatred by a painful loss (Lockwood's father, Manchester's fiancée), but unlike Lockwood, a hatemongering Dirty Coward and Absolute Xenophobe, Manchester believes in the rights of aliens, can more than handle himself in a fight, and would have married an alien if Lockwood hadn't murdered her. Lockwood becomes a government official, while Manchester embraces his criminal roots. As time goes on, however, their similarities become more apparent, as they both use public forums to drum up support for their cause, ruthlessly murder those who they feel have it coming, and are both willing to incite violence against the opposite side.
- From Nobody to Nightmare: Started off as nothing more than a mild-mannered history professor with a family before gradually becoming a radical xenophobe and terrorist.
- The Heavy: While Lex Luthor is the actual Big Bad of the Season, Ben is still the most consistent threat the heroes have to deal with in Supergirl Season 4.
- Helmets Are Hardly Heroic: When he starts wearing his Agent Liberty outfit again in "American Dreamer" and "The Quest for Peace", Lockwood stops wearing his mask.
- Despite Lockwood's xenophobia and hatred of all things alien, he has no problem using aliens to his own advantage; he uses alien tech and the captive Fiona to brainwash aliens for a False Flag Operation, and infects Jensen with an alien parasite to use him as a living weapon against aliens.
- Among Lockwood's philosophies is "we don't kill humans" and "humans won't let humans down". These claims would carry more weight if his plans didn't include using brainwashed aliens to attack innocent people to spread fear and forcibly infecting Jensen with an alien parasite.
- Upon being unmasked to the public, Lockwood rails against Supergirl, claiming that he's shown his true face to the public, and that she should as well. True to form, he neglects to mention that he was unmasked by force, and up to then, was happy to hide behind the mask of Agent Liberty.
- All of Lockwood's claims of putting humans first, the message being more important than any one man, and never harming humans fly out the window when one of the Children of Liberty talks down to him and tries to usurp control of the group; Lockwood brutally murders the man to reassert his authority, and makes it clear that he's willing to do the same if anyone else feels like challenging him.
- Irony: He's an anti-alien xenophobe, but the one who hates him the most and the only one who sincerely wants to kill him is Manchester, a fellow human.
- I've Come Too Far: Upon learning everything he's achieved and sacrificed for has been solely to further Lex Luthor's own ends, Ben continues his crusade of violence. Not because of faith in his principles, but because there's literally nothing left for him but to lash out until his Super Serum poisons him or someone puts him down like an animal.
- Jerkass: After descending into bigotry, and especially after being appointed to President Baker's cabinet, Lockwood is a smug, shamelessly cruel piece of work who abuses his authority and threatens the spouses of aliens he arrests for no good reason.
- Jumping Off the Slippery Slope: He makes the leap from bigot and Rabble Rouser to xenophobic murderer when he bludgeons an alien factory worker to death.
- Karma Houdini Warranty: Due to his supporters rising numbers, President Baker eventually relents and sets him free, due to his acts of terrorism supposedly only targeting aliens and not humans -- even though humans have been hurt and targeted in some Lockwood's plans -- specifically his plan to brainwash an alien to attack humans. And then Baker appoints him Director of Alien Affairs. However, at the end of Season 4 he is finally rearrested, alongside Baker. And he has to watch from prison as his son sets out do undo all of his hateful work.
- Knight Templar: He considers himself righteous for murdering aliens, believing that their presence detracts from the human race.
- Lack of Empathy: While he does sincerely love his wife and son, Lockwood has zero empathy for aliens (which he shamelessly admits to), and his regard for other humans tends to vary, although he'll seldom allow things like collateral damage or loss of innocent life to dissuade him from his plans.
- Large Ham: Lockwood is eloquent, charismatic, and passionate, which lends itself well to some dramatic speeches, along with some epic rants whenever he suffers a Villainous Breakdown. As he becomes more vicious and his mental state grows more fragile, Lockwood develops a tendency to snarl animalistically when he gets angry.
- Laser-Guided Karma:
- His murder of Fiona ultimately leads to Manchester Black hunting him and cornering him at his house, exposing his secret identity to the world and getting him arrested.
- His wife Lydia is eventually murdered by the wife of an alien he personally arrested for no reason other than sheer spite.
- A Lighter Shade of Black:
- He is a murderer and a fanatic, but he comes off as relatively better than the Graves siblings; where they have no qualms at all about killing humans, he refuses to ... at first.
- Lockwood is a loathsome fanatic with increasingly few redeeming qualities, but he's definitely this compared to Lex Luthor, a narcissistic maniac whose selfish machinations have endangered the entire world.
- Malevolent Masked Men: He's mostly seen with his mask on and he's definitely not a nice guy.
- Moral Myopia: Agent Liberty balks at murdering humans. The man himself murders helpless aliens in cold blood as a matter of course. Even worse, he comes up with a plan to foster fear of aliens by siccing mind-controlled alien prisoners on a fair full of children; in his mind, this just proves to people that aliens are something to be feared.
- Never My Fault:
- He holds the alien student that he insulted responsible for the loss of his job, despite the fact that he made a blatantly racist comment about her in the middle of a classroom full of fellow students, only the latest in a series of such incidents according to the dean. As it turns out, the student didn't even report him.
- When an ill-conceived plan of Lockwood's fails to capture Supergirl, he only reports to President Baker that she "outsmarted the DEO".
- No Celebrities Were Harmed: His civilian identity as a charismatic commentator who espouses derogatory views on minorities, brings to mind various controversial right-wing commentators, most notably Ben Shapiro, with whom Ben shares an uncanny resemblance and first name.
- Non-Action Big Bad: Lockwood is a teacher turned terrorist and understandably lacks any combat training. He stays out of fights if he can help it, delegating the ground work to his followers. When Manchester Black catches him at home, the best Ben can manage is to run from him. This is later averted when he injects the Harun-El into himself.
- Not-So-Well-Intentioned Extremist: Lockwood claims, and seems to honestly believe that he founded the Children of Liberty to help people who feel oppressed by the presence of aliens, and who have suffered from alien attacks. Actually examining Lockwood's actions reveals his motives to be little more that hatred, bigotry, and xenophobia; Lockwood dresses up his hate speech with a lot of eloquence and charm, but he ultimately can't disguise how hateful and cruel he really is.
- Pragmatic Villainy: Is against the use of using the dispersal bomb to lace the atmosphere with kryptonite because it would do more bad than good to the movement by making Supergirl a martyr. Mercy ignores him.
- Rabble Rouser: He's a capable demagogue, speaking in front of crowds to rally them against aliens.
- Remember the New Guy?: He is retconned into having met half the show's cast at some point, and is present during the events of several episodes. However, most of these interactions are brief from their perspective, so they have no reason to remember him.
- Sanity Slippage: As his life falls apart from one alien-related event after another, Ben goes from mild-mannered and open-minded to xenophobic and murderous. His mental health declines even further as time goes on; the once-Dirty Coward brutally murders a would-be usurper, and his Villainous Breakdowns start changing from ineffectual ranting to nearly psychotic screams and snarls.
- Slowly Slipping Into Evil: Ben Lockwood's descent into bigotry and murder didn't happen all at once. Over the course of several alien-related events, he developed a deep-seated hatred for anyone not from Earth, and took to murdering them after killing an alien in a drunken rage.
- Smug Snake: He is unbelievably arrogant and just an outright dick whenever he feels like he has the upper hand. Whenever the tables turn however...
- Sorting Algorithm of Evil: He is one of the least physical threats that Supergirl has faced up until now, but the reason he's so dangerous is because he tends to invoke You Cannot Kill An Idea, while successfully corrupting others to his way of thinking.
- Start of Darkness: His corruption starts when his father's steel factory starts losing business to an Nth metal refinery, and his father's death during Reign's attempt to terraform Earth finished the job.
- Took a Level in Badass: After taking the undiluted Harun-El, he becomes strong enough to easily overpower Nia, James and Brainy. J'onn however is still too much for him. Also, as it turns out, the undiluted serum is taking a toll on his health.
- Tragic Bigot: Lockwood was once a mild-mannered professor who fought for alien rights. But when an alien he was defending from a mob accidentally injured him, Lockwood's faith was twisted into irrational hate.
- Trauma Conga Line: Being accidentally injured by an alien, his family business going bankrupt, having his home destroyed by J'onn fighting a Daxamite, losing his job for his radical views, and watching his father die in a collapsed building during the Worldkillers' attempted terraforming of Earth turns a tolerant professor into a genocidal killer of aliens.
- Ungrateful Bastard: Supergirl stops Manchester from killing him - he proceeds to blame Supergirl for the injuries Manchester gave him and manages to turn public opinion against her.
- Unwitting Pawn: Unknown to him, his entire movement is one — the Graves sought him out on Lex's orders. When he finds out, he is naturally not happy.Ben: Otis, so you're saying that everything that's happened, all of this, you're telling me that it's all about money?
Otis: And world domination. It's kind of his thing.
- Villainous Breakdown: Lockwood doesn't take defeat very well. He tends to brood over any failure with his plans, and he develops a very short fuse whenever he's thwarted.He has an especially big one when he finds out that he has been nothing but a pawn in Luthor's schemes.
- Villain with Good Publicity: Despite losing his teaching job, Lockwood remains a figure of some standing, being a respected speaker among anti-alien groups and invited to attend ceremonies at city hall. Disturbingly, this has little to do with actually hiding his racist views; he simply hides his criminal activity and openly presents himself as very pro-human and anti-alien, but he still manages to gain support from normal people who aren't open to aliens and city officials who see aliens as a problem. Lena and James are unsettled to hear the Mayor of National City himself say that Lockwood's views might be more common than they think. Even when he's unmasked in the winter finale, he's still this as the right-wing media dubs him a "human rights activist" (ignoring the numerous crimes orchestrated by him) and the xenophobes of National City eat it up, protesting his arrest.
- What You Are in the Dark: He was originally tolerant of aliens, but when the time came to practice what he preached - especially when he was accidentally injured by one because its natural defense mechanism went off because he was being attacked - he showed what he really was.
