National City CitizensMedia
Portrayed By: Ian Gomez
Voiced By: Dafnis Fernández (Latin-American Spanish dub)
First Appearance: "The Last Children of Krypton" (Supergirl 2x2)
A veteran newsman hired by Cat Grant to be the editor-in-chief of CatCo magazine.
- Adaptation Deviation: Snapper Carr was a non-powered member of the Justice League of America, and generally the mascot of the group. He's in a position of authority in this show.
- Adaptational Ugliness: While cute and young in the comics, is a balding middle aged man here.
- Age Lift: Like Cat, a good twenty years older than his original comic incarnation.
- Ambiguously Jewish: Snapper quotes a Yiddish phrase told to him by his grandmother.
- And Starring: Gets this citation in the guest stars lineup.
- Berserk Button: In "Exodus", you finally get to see what Snapper looks like when angry after Kara publishes a story independently. He drops the Deadpan Snarker facade and shows his real emotions, and you finally see the real Snapper.
- Brutal Honesty: He may not care if you enjoy hearing it, but he'll give it straight - at least when it comes to his profession.
- Composite Character: Snapper's personality is more akin to Perry White's.
- Da Editor: He is Kara's superior, though technically, James still possess the highest authority due to being Cat Grant's proxy CEO. However, after putting his foot down, it seems James defers to Snapper's judgment. Overall, it's mostly a case of, as James puts it, "you stay in your lane and I'll stay in mine."
- Expy: Snapper's appearance and personality are highly similar the character of Mr. Grant from the Mary Tyler Moore Show
- Guttural Growler: Speaks with a very rough, deep voice, compared to his actor's much normal voice.
- Intrepid Reporter: Despite being a busy, out of shape and middle-aged magazine editor with no superpowers, still manages to find incredibly difficult leads, even dealing with life-threatening situations.
- Jerkass Has a Point:
- He's not nice about it, but he's also not wrong when he says you don't get to say you're a reporter because you "chose" the job. You have to earn it.
- In his second episode, he's right that you can't let your personal biases get in the way of reporting honestly. His reporter instincts are also dead-on.
- In "Survivors", when Kara comes up with a legitimately important story, he shows interest, but runs down the list of things she needs before he'll consider it: sources, leads, and so on before he'll even take it. He dismisses anything less than a solid foundation, saying CatCo isn't Reddit. When she does get first hand evidence (police reports, forensics, an official source in the name of Supergirl), he criticizes that she still needs to work on her writing (run-on sentences, needs to follow AP style), but he does compliment the fact that she's developing sources and marks it as an official story she's working on.
- In "Exodus," he fires Kara for publishing a story independently. He'd held her back from publishing because she lacked attributed and independent sources, and even says that while she was right this time, she "got lucky." It's clear he doesn't want to fire her, but feels he has to because it's such a clear breach of rules.
- Most antagonistic journalists in a superhero series would be either trying to reveal the superhero's secret identity or making their lives harder through, at best, creative journalism and at worst outright libel. Snapper Carr, on the other hand, is an antagonist because he's too moral, with his strict By The Book attitude regarding the rules of journalism preventing Kara from exploiting her secret identity to aid her own status as a reporter, ala Peter Parker or classic depictions of her cousin Clark Kent. This is taken to its ultimate conclusion in "Exodus" where, because Kara can't provide attributed & independent sources, since she knows the story by A: being Supergirl, and B: working with the strictly-off-the-books DEO, he won't publish her story. When she goes behind his back and publishes it independently, he fires her, citing that just because she "got lucky" this time doesn't mean she couldn't have been wrong and so caused a panic.
- Jerk with a Heart of Gold: Hostile towards Kara, though for admittedly good reasons. She's a rookie reporter and his criticism challenges her to improve rather than automatically assume that she's going to be amazing at it. Despite his hostility, he cares about doing his job in as honest a manner as possible. Conversely, he may think Kara will be an amazing reporter, which would make him more eager to drive home his instruction.
- Mean Boss: He's not an easy man to work for — and lord help you if done something that warrants you be dismissed; he'll pack up your belongings in a box on your desk, waiting to be found by the unsuspecting employee.
- Meaningful Name: The comic book Snapper Carr got his name from having the tic of snapping his fingers. This Snapper Carr just, well, snaps at you verbally.
- Must Have Caffeine: Snapper's definitely not a morning person: priorities are coffee and danish first thing, that's it.
- Put on a Bus: It's mentioned that he has gone on sabbatical from CatCo in "Girl of Steel".
- Reasonable Authority Figure: In "Supergirl Lives", Snapper (rightfully) is aghast Kara would promise a mother she would return her child, which is perfectly reasonable since he has no idea Kara is Supergirl. He's not impressed when Kara succeeds, because it's putting too much on her plate as a reporter (again, not knowing what her other identity is.) However, he does not tell her to stop as her boss. Instead, he just shrugs and warns her she may burn out and it'll cost her a fortune in psychiatry bills. As he notes as soon as she leaves with his "That-a girl, Danvers," he's trying to get her to follow her intuition to be the best reporter she can be, and he actually is proud of her work. He just knows better than to show it.
- So Proud of You:
- In "Supergirl Lives", he says "That-a girl, Danvers" after Kara stands up for herself and has left, after saying she'll always choose the stories she's passionate about. Subverted sadly in "Exodus" when he tells her to her face that he'd always been rooting for her — as he's firing her.
- In "Ace Reporter", he heaps on praise for her being The Determinator in the face of danger, and because of her dedication to the truth over any personal issues with him. It ends with him re-hiring her.
- What Happened to the Mouse?: Disappeared after Season 2.
Nia Nal / Dreamer
Species: Human-Naltorian Hybrid
Portrayed By: Nicole Maines
First Appearance: "American Alien" (Supergirl 4x1)
Appearances: Supergirl | Crisis on Infinite Earths (2019)
A fresh reporter for CatCo who is a member of a species that specializes in prophetic dreams. When she becomes aware of these abilities, she decides to assist Supergirl, using the name "Dreamer".
- Action Girl: She turns into one upon discovering her powers and becoming Dreamer. Nia is taught how to fight, both with her powers and without them, and becomes a highly effective combatant.
- Alliterative Name: Nia Nal.
- All-Loving Hero: She is accepting of aliens. It's clearly demonstrated when she defends Brainiac 5 from anti-alien pizza deliverers. She says it reminds her far too much of transphobic violence. Nia is half-Naltorian and thus half-alien herself as well, we learn later (another obvious motive).
- Astral Projection: One of her abilities.
- Big Sister Worship: She really looks up to Kara, who is her mentor both at work and in the superheroine business.
- Boxing Lessons for Superman: Brainy puts her through these, since much of her powerset isn't combat-useful.
- Coming-Out Story: Nia comes out a couple times to her new acquaintances/friends in Season 4 (she was already out to her family, and they accepted her).
- In "Fallout" Nia tells James she is transgender, while explaining why she'd stood up for Brainy since it had reminded her of transphobia. James is cool about it.
- In "Blood Memory" she tells Kara, and also relates her transition in the past. Her family was very accepting, though not everybody in her town was okay about it. Kara thanks Nia for sharing her story, and is also wholly accepting of her identity.
- In "American Dreamer" she comes out again while giving an interview to Kara, this time as Dreamer, to the entire world.
- Cultured Badass: Downplayed, but she's a good enough writer to impress Cat Grant, worked for the White House at a young age, and loves fashion.
- Dreaming of Things to Come: Primarily, she has prophetic dreams. Brainy is training her to use it as a form of Combat Clairvoyance and expelling raw "dream energy" as means to be on the offensive.
- Endearingly Dorky: What else do you call someone who suggests pulling a Wookiee Gambit? She's compared to a younger Kara by Kara herself within two minutes of their first meeting, thanks to Nia's eagerness and Motor Mouth.
- Et Tu, Brute?: Her sister Maeve is angry when it turns out Nia's got their family's prophetic dreams (which are passed down from mother to daughter), saying that Nia "isn't a real woman" so it should be her. Nia is shocked and hurt, because Maeve previously had been her greatest supporter as she transitioned.
- Famous Ancestor: Nia is the ancestor of Brainy's Legion teammate Nura Nal, who is also/will be Nia's successor as Dreamer.
- Future Badass: From Brainy's point of view.
- Half-Human Hybrid: She and her sister Maeve are the offspring of a human father and a Naltorian mother, as shown in "Blood Memory".
- Internal Reveal:
- Nia tells James she is transgender first, so the audience knows, then Kara a few episodes later.
- Nia reveals her dream powers to the rest of her family, though her sister doesn't take it well to say the least.
- Interspecies Romance: Nia gets involved with Brainy in Season 4, though their romance turns out to be really more on-again/off-again. She is half-Human, half-Naltorian, he's Coluan.
- It's Personal: In 5x15, when a transphobic man attacks her roommate in order to shut down Dreamer, it is obviously very personal.
- Motor Mouth: Occasionally, to Kara Danvers levels.
- Nice Girl: She's a very sweet and kind young lady.
- Noodle Incident: She once broke her nose playing kickball.
- Oh, Crap!: She visibly freaks out when Brainy leaves her in the cell during "Red Dawn."
- OOC Is Serious Business: When she goes after the man who attacked her roommate (see It's Personal above) Nia's usual warm, lovable nature vanishes, to be replaced by Oliver Queen-esque Tranquil Fury.
- Out of Focus: She's been given Guardian's treatment, barely helping Supergirl in most struggles and is occasionally absent for entire episodes.
- Pop-Cultured Badass: She mentions in her TV broadcast that she enjoys Harry Potter and A Song of Ice and Fire, amongst others. In the penultimate episode of season 4, she suggests and name-drops the Wookiee Gambit. Later, she mentions that J'onn and M'gann's decoy plan is similar to Harry Potter and the Deathly Hallows.
- Refusal of the Call: She tries this for a number of episodes until she gives in to the Call and becomes Dreamer.
- Relationship Revolving Door: She goes through some UST with Brainy, and hooks up with him during the Season 4 finale. He walks out on her a few episodes later. They're left in limbo (see Out of Focus) until Crisis, which seemingly reboots them, as they're seen holding hands afterwards... only for him to dump her again.
- Relationship Upgrade: She and Brainy become a couple during the Season 4 finale. Then inverted when he dumps her a few episodes later.
- Sleepyhead: Nia has a habit of falling asleep at her desk. She claims it's due to suffering from narcolepsy, but it turns out that it's because she has been avoiding sleeping due to her Dreaming of Things to Come powers making her dreams terrifying and hard to understand. Kara and Brainy help her with these powers and eventually, she is able to deal with these dreams and have restful sleep again.
- Supernaturally Validated Trans Person: Her oneiromantic powers are a Gender-Restricted Ability that is inherited by one woman every generation in Naltorian families. Nia being the one to inherit this ability reaffirms her identity as a woman. This surprises her family, who, even though they accepted Nia's transition, fully expected her sister Maeve to get the abilities and never even considered that Nia might have inherited them instead.
- Trademark Favorite Food: She loves breakfast burritos.
- Transgender: She is a trans woman, just like her actress.
- Twofer Token Minority: She's a transgender woman and also half alien.
- Working with the Ex: She clearly has trouble with this during "Back to the Future."
Portrayed By: Jaymee Mak
First Appearance: "American Alien" (Supergirl 4x1)
A new CatCo reporter as of Season 4.
- Broken Pedestal: As of "Crime and Punishment", any faith and respect she had for Supergirl fades when she becomes a public enemy for attacking the White House when it's actually the Red Daughter who pulled the attack.
- The Gadfly: She pulled a prank on her alien coworker Franklin, putting strips of wood in his coffee, since that was his natural diet. James was not amused, especially because of the rising hatred against aliens. She later apologizes.
- Intrepid Reporter: She starts investigating LCorp, after getting a lead on their illegal genetic experimentation. Unfortunately, James puts a stop to this due to his personal connection with Lena.
Portrayed By: Sean Hewlett
First Appearance: "Fallout" (Supergirl 4x2)
A new CatCo reporter as of Season 4, a Dryad.
Portrayed By: Julie Gonzalo
First Appearance: "Event Horizon" (Supergirl 5x1)
The new owner and head of CatCo as of Season 5.
- Adaptation Dye-Job: Andrea is a redhead in the comics. Here, she's a brunette.
- Adaptational Jerkass: She is a superhero in the comics, but a colossal, self-centered jerk in the show.
- Adaptational Job Change: Andrea in the comics wasn't a tech mogul, but an anthropologist. This extends to her father.
- Adaptational Nationality: The original Andrea Rojas was Mexican, but this version is Argentine like her actress.
- Adaptational Wimp: She isn't a fighter or acrobat like in the comics, although she has Acrata powers.
- Ambiguously Evil: William Dey believes she's at the centre of a huge criminal conspiracy. Partly confirmed in Episode 5: she is part of a huge conspiracy but she is also Trapped In Villany.
- Bitch in Sheep's Clothing: Acts all nice and quirky, but as soon as something doesn't go her way, she outright threatens to ruin somebodys life.
- Deal with the Devil: She took the medallion Lena was searching as it gave her the means to save her father. However, this in turn forced her into becoming an assassin for Leviathan.
- Historical Character's Fictional Relative: Her uncle is Elon Musk. Assuming that things are the same as on our Earth, presumably her mother is Elon's real sister Tosca.
- In Name Only: Andrea Rojas in the comics is a Mexican anarchist vigilante called Acrata who becomes an ally to Superman and saves the world alongside him and the Mexican heroes El Muerto and Iman. Andrea Rojas in the show is a sleazy, money-grubbing mogul/heiress from Argentina who becomes an antagonist to Supergirl and her friends, and is trying to destroy CatCo's integrity for the sake of capitalism. They basically created a whole new character and gave her a different one's name because they were both Latin American.
- Living Shadow: The amulet gave her the power to become this. And it seems like she is keeping these abilities even after losing it.
- Mean Boss: And how. Both Cat and Snapper seem harmless next to her.
- Took a Level in Kindness: As the 5th Season goes on, she is steadily humanized.
- Trapped in Villainy: She is under Leviathan's thumb and desperately wants out.
- We Used to Be Friends: She and Lena were best friends, until Andrea kept the medallion Lena had been searching for her entire life.
Portrayed By: Staz Nair
First Appearance: "Event Horizon" (Supergirl 5x1)
A new CatCo reporter as of Season 5.
- Ambiguously Evil: He is clearly involved in something unethical, probably Leviathan, but it seems like he is in the same position as Eve Teschmacher before him. Then it turns out that he isn't evil, he is trying to uncover Andrea's corruption.
- Broken Pedestal: Kara used to have a good opinion of him, as long as he worked for The Times of London, but is very disappointed when she gets to know him. She seems to start to reconsider after his true motives are revealed.
- Good All Along: He isn't evil, and not even a dick. He is trying to uncover a massive criminal conspiracy.
- Hidden Depths: Despite his scummy behavior, he also works at a soup kittchen. That's because he is really a Nice Guy.
- Informed Ability: He's supposed to be a top journalist who won two Pulitzers, but so far he does a downright pathetic job at it.
- Intrepid Reporter: He is willing to go to Leviathan's place.
- Jerkass: Outright sabotages Kara's work to score points with Andrea. It's all an act.
- Love Interest: Eventually for Kara, as Season 5 goes on.
- Out of Focus: Despite being Kara's love interest (and implied by Winn to be her endgame love interest), he barely features in the first half of season 5 (in fact he the lowest screentime out of the main cast as of 513) and misses several episodes. His only significant role was making Kara aware of a larger conspiracy (Leviathan), but fades away as Kara starts doing all the work for him.
- When Kara was sent to the Phantom Zone at the start of season 6, he only makes brief appearances without significant contribution to the plot (presumably to remind the audience he still exists)
- Satellite Love Interest: Appears to have no other role than to be Kara's boyfriend. Originally he was investigating Leviathan and Lex Luthor, but Kara keeps distracting him.
- Taken even further at the beginning of Season 6 when Kara is trapped in the Phantom Zone. Without Kara around, William has no real role and literally spends most of one episode watching lex's trial on TV.
- Suspiciously Similar Substitute: He has a similar role to James Olsen's in Season 1 as a love interest for Kara working as an Intrepid Reporter for CatCo.
- Yes-Man: Towards Andrea, and unashamed so. All to get close to her.
Catherine J. "CJ" / "Cat" Grant
Portrayed By: Calista Flockhart, Eliza Helm (young)
Voiced By: Liliana Barba (Latin-American Spanish dub), Eri Miyajima (Japanese dub)
First Appearance: "Pilot" (Supergirl 1x1)
The founder of CatCo, a powerful media conglomerate, and Kara's former boss. In Season 2, she decides to go on a long sabbatical and leave James in charge.
- Adaptational Heroism: She was an incredibly unapologetic Alpha Bitch in the comic books (pre-Flashpoint), and her only interaction with that version of Supergirl was a mud-slinging campaign (brought upon because of Kara accidentally breaking her arm when saving her life) so brutal that Kara swore to never save her life again. This version is a Jerk with a Heart of Gold that has no problem giving Kara a necessary pep-talk... and then order her to go get her a latte... or try to draw a super villain away from her employees.
- Adaptational Modesty: Cat Grant in the comics showed off her boobs, while Cat Grant in this series fully covers her torso and is never sexualized.
- Age Lift: In the comics, Cat Grant is usually within the same age range as Clark Kent/Superman, even being a potential romantic partner for him prior to Lois Lane. In this series, Superman is at least 36 years old, whereas Cat is portrayed by Calista Flockhart, who is 50. Admittedly, though, Calista doesn't look fifty. Considering she was revealed to have a son in his mid-twenties, she can't be that much younger.
- And Starring: Credited this way in the series OBB, along with David Harewood. After being demoted to recurring role starting Season 2, she falls into "Special Guest Star" but still with the "And" citation.
- Animal Motif: She has been compared, obviously, to cats.
- Awesomeness by Analysis: It's almost as if her superpower is the ability to know a superhero's alter ego before anyone else does. She deduces thats Kara is Supergirl due to how she conveniently leaves before Supergirl arrives at the scene. She also figures out that Barry is the Flash simply because he arrived at National City at the same time the new speedster did, and that James is Guardian due to how she easily recognizes that a black man is wearing the suit via the gap between his eyes.
- Big Bra to Fill: Played With. Cat is portrayed by the modestly endowed Calista Flockhart, but her comic counterpart has breast implants which she regularly flaunts.
- Broken Ace: Her competitive, "always go for the win" attitude is revealed to have been partially fueled by her mommy issues.
- The Bus Came Back: She comes back in Season 6, during a trip to the past, though portrayed by a different actress.
- Cat Smile: Appropriately enough. Her actress is known for having this trait, which she does even in this show (see her page image).
- Celebrity Paradox: Star Wars is acknowledged to exist in this universe despite the fact that her actress is married to one of the lead actors of the franchise in Real Life. In "Myriad", there's a reference to the wife of the aforementioned actor, meaning it's possible that Cat and Calista Flockhart exist in the same universe.
- Character Development:
- With Flockhart unable to continue the show, this had the effect of having Season 1 be a subplot of Cat Grant sliding from cynicism to idealism to the point where she had the courage to completely re-prioritize and choose family over work.
- Cat goes from antagonistic to Kara to a maternal mentor and steadfast ally.
- Cold Ham: She loves delivering her lines in a "theatrically subdued" manner. Unless she's calling someone, that is.
- Deadpan Snarker: When commenting on Kara's rough start as a hero, she says "Oh, what is the opposite of super? #Terriblegirl?"
- Decomposite Character: The one to mock Supergirl is Leslie, not Cat.
- Defrosting Ice Queen: To both Kara and Supergirl. How much of that is due to them living up to her Tough Love standards and how much is due to her son, Carter (who opens up after Kara watches him for an evening and has a massive crush on Supergirl), remains to be seen.
- Demoted to Extra: She was downgraded to a recurring role in Season 2, in a case of Real Life Writes the Plot after the show's production moved to Vancouver, as Calista Flockhart is famously uncomfortable working outside Los Angeles. Makes a cameo in the Season 3 premiere, where she is now the Press Secretary to President Marsden.
- Dramatic Irony: Cat initially doesn't want to hire Kara because she doesn't like Millennials, not knowing that Kara is a member of Generation-X like Cat herselfnote .
- Easily Forgiven: A Red Kryptonite-influenced Kara nearly kills her in "Manhunter", forcing Cat to publicly denounce Supergirl as a threat. Still, rather than turning completely on her, Cat encourages Kara to regain the public's trust/faith in her.
- Eating the Eye Candy: Goes wide-eyed and flirtatious whenever Clark is around, and blatantly admires his backside at one point.
- Everyone Has Standards: She's unashamedly a cold and calculating media mogul, but she's genuinely impressed by Supergirl's status as a Hope Bringer and makes an effort to pander to the city's new-found optimism by punishing Leslie Willis for ragging on her.
- Expy: If you think Cat seems a lot like Miranda Priestly, it's not an accident. The character description when the role was being cast was specific in that the character was Miranda with the Serial Numbers Filed Off.
- Friendly Rivalry:
- With Perry of the Daily Planet, the two compete with one another, but they still respect each other as colleagues.
- Likewise with Lois Lane, the two make snappy remarks at one another but ultimately see each other as close friends.
- Good Is Not Nice: Ultimately, Cat is not a bad person in any real way. She's casually rude and kind of selfish, but she cares about people and is honest to a fault. She points out that what happened to Leslie wasn't Supergirl's fault and that if anyone should feel guilty, it's Cat (though she claims she doesn't).
- Good Parents: While Cat's demanding career keeps her from being the most attentive parent, she is still caring and supportive of her son Carter. She even recognizes that he is a "special" child with specific needs. And she would even give up her career rather than let her oldest son, Adam, get caught in a media scandal.
- Hopeless Suitor: She has a thing for Clark Kent and asks if her prediction that he and Lois break up came true.
- Horrible Judge of Character: Played with. Cat has an excellent eye for talent; she even pegged Kara as a future reporter the second she met her. However, she also hired Leslie Willis and Siobhan Smythe, who turned out to be talented but also nasty pieces of work.
- Hypocritical Heartwarming: Only she is allowed to be rude to her employees, thank you very much. Her mother runs afoul of this in "Red Faced" and gets a tongue-lashing for it.
- Incoming Ham: You know she's about to enter the scene when she's calling for Kara from afar.KYRA!
- It's All About Me: When Kara comes in to complain about naming her "Supergirl" instead of "Superwoman," Cat immediately shuts her down with a faux-feminist speech about how "it's good to be a girl" (ignoring what Kara was actually saying), then talking about what Supergirl is doing only in terms of herself and her media empire.
- Jerkass Has a Point:
- Though couched in an It's All About Me attitude, her reasoning for using the name "Supergirl" isn't exactly wrong. If critics perceive a "Supergirl" to be somehow less than a "Superwoman," then the real problem is how they choose to interpret the words, not the words themselves.
- In "Stronger Together", she similarly points out in her own idiosyncratic way that Supergirl should not be tackling jobs such as catching planes falling from the sky while she's so inexperienced because she causes more harm than good. Instead, she should be more like Kara and work her way from the bottom up. Supergirl takes this to heart.
- While she's dismissive and tells Kara she's useless in "Livewire", she does so because Kara (who she thinks is an ordinary person) can't possibly do anything against Livewire and she probably has friends and family to see on Thanksgiving.
- In her typical good but not nice way, she points out that asking "how do you do it?" to a mother and career woman is annoying because of the implicit "you shouldn't be ABLE to do it all" that it carries and gives practical advice— start slow, and take things one at a time.
- She refuses to help Kara with Snapper even though as CEO, she could tell Snapper to take her. However, she knows that 1) Snapper is the sort who would just leave CatCo and find good work elsewhere, and 2) even if Snapper didn't leave, he'd be resentful towards Kara and not give her a chance to do good work, and 3) even if Cat weren't leaving, Kara was getting too dependent on her and it was time to Shoo the Dog.
- Jerkass Ball: She becomes a bigger jerkass towards Kara after Kara breaks up with her son, resulting in hiring a new assistant she designates as number one. It doesn't last though.
- Jerk with a Heart of Gold: "Livewire" reveals that she's terrible with people, but she does care. As soon as she hears Kara has a foster mother, she's intrigued, and when she learns her parents died when she was a teen, she's sympathetic. Also when the titular Villain of the Week attacks, she doesn't leave Kara behind when attempting to escape and willingly risks herself to the villain in order to buy Kara more time to run away and call for help.
- It's also made clear in that same episode that while she will criticize Supergirl's actions, she is truly angry when Livewire insults Supergirl's body and sexuality.
- Another good example is when Supergirl/Kara is under the influence of red kryptonite and decides to see if "Cats" really do land on their feet. Supergirl saves Cat at the last moment but Cat is forced to issue a public announcement warning that Supergirl has become a danger to humanity and is extremely broken up over this. When a cured Supergirl returns to apologize, Cat accepts it and encourages Supergirl to win back the public's faith in her.
- Knight in Sour Armor: She's extremely cynical, but as the series goes in, it's obvious that she is actually idealistic but believes that's unavailable to her because it's a Crapsack World.note
- Malaproper: She consistently gets people's names wrong (when she even recognizes them). Kara is Kyra, Winn becomes Wit... In the final episode of the first season, it's strongly implied she deliberately mispronounces their names as a power move.
- Mean Boss: TV Guide has described her as "A Devil Wears Prada-type boss." Almost fires Kara for suggesting "Superwoman" instead of "Supergirl," which she coined. Also, she consistently mispronounces Kara's name.
- My Greatest Failure: She once had firsthand knowledge that a well-liked actor was abusive towards his wife. She was pressured into making her story about him a fluff piece instead of a truthful one, and he killed his wife a few weeks later. She tells this story to Jimmy in an effort to show him the importance of doing the right thing.
- No Celebrities Were Harmed: Described as "J. Lo by way of Anna Wintour" in casting calls.
- Odd Friendship: She and Kara seem to have this relationship. Cat is more of a Good Is Not Nice person, while Kara is clearly nice for the most part.
- Older Than They Look: A more mundane example. In "Hostile Takeover" it's suggested that she's older than she appears and that she's been lying about her age, as she was hacked and one of the things the hacker published was her true age. Her actress, Calista Flockhart is 51, but certainly doesn't look it.
- One Steve Limit: She and her mother share the same name aside from a different letter at the very beginning.
- Parental Substitute: To Kara, of the Tough Love variety now and then, but it becomes more and more obvious as the show goes on. She doesn't outright say it, but by season 2 she talks to Kara like she's the daughter she never had.
- Put on a Bus: Decides to leave CatCo in the second episode of Season 2, due to Calista Flockhart's established refusal to work outside of Los Angeles.
- Red Baron: She's known as "The Queen of all Media". Doubles as her Badass Boast.
- Secret Keeper:
- She's the first person to deduce that Kara is Supergirl on her own, without somebody who already knew telling her. In the next episode, however, Supergirl had help from Martian Manhunter to convince Cat she's wrong, though it's implied she wasn't actually fooled by the deception. The Season 2 finale confirms that she knows, making her a Secret Secret-Keeper.
- She easily figures out that Barry Allen is the Flash, since he appeared when The Flash appeared, he was adamant that he should be called the Flash and he was a Nice Guy.
- Averted with James as Guardian, as she immediately tells Clark about this.
- Self-Made Woman: She went from being the girl who brought Perry White's coffee to being the owner of a huge media conglomerate through hard work and dedication.
- Serial Spouse: Tells Kara in the Season 2 finale that she was married four times. It's not stated which of them are Adam and Carter's respective fathers.
- Silk Hiding Steel: At first glance you'd think she's a comical Dirty Coward, but she's actually pretty brave as she doesn't hesitate snarking at her now superpowered ex-protegee more than once.
- Single Woman Seeks Good Man: As with the comics, Cat carries a torch for Clark, partly due to his Midwestern looks and values.
- Sitcom Arch-Nemesis: Her relationship with Lois Lane in a nutshell, since Cat rarely goes for a whole episode without saying something nasty or competitive about Lois.
- So Proud of You: While she never would admit it to her face, she does express a sense of pride in Kara.Cat: (quietly to herself after watching Kara go to save the day) Go get 'em, Supergirl!
- Spotting the Thread: Cat is very observant, spotting even the smallest details about something or someone. She easily figures out Kara's, James's, and Barry's alter egos.
- Start My Own: She apparently got fed up with being a worker at the Daily Planet, so she started her own company.
- Stealth Mentor: Her scoldings and lectures (see Jerkass Has a Point) actually contribute to Kara's Character Development, regardless if she intends it or not.
- In an unusual play on the Stealth Mentor trope, Kara already seems to see her as that, almost to the point of being a Stealth Student. Even though she legitimately dislikes the rude and dismissive way Cat treats her most of the time, Kara still looks up to her, cares about her and values her advice regarding whatever situation she's dealing with (whether or not Cat realises she's advising her and what she should do as Supergirl). This is likely why Kara genuinely wants to keep working for her.
- Time-Shifted Actor: Her 2009 self is portrayed by Eliza Helm.
- Tsundere: She is often harsh to her employees, including Kara, but she does care about Kara a lot, as well as Ashley, despite what she says about not feeling guilty about what happened to her. She is also quite sweet to her son Carter.
- Tranquil Fury: She never raises her voice in anger, but when she gets mad, there's no mistaking it. She teaches Kara this skill, telling her that she needs to channel and control her fury, not just let it burst out.
- Two First Names: Per the DC Comics norm.
- Vitriolic Best Friends: The reason that Cat can say such horrible things about Lois, is honesty not malice, and she openly admits the two are very close friends despite the rivalry.
- Weirdness Magnet: Granted, she's the publisher of a major media company, but she's now had two supervillains in her employ (granted they didn't become supervillains until after they stopped working for her but still) a superhero as another, not to mention a crush on yet another. Despite this, she tells Kara that "she can spot the extraordinary pretending to be ordinary" in a moment.
- "Well Done, Daughter!" Gal: In a conversation with Kara, she reveals that she always tries her best to be the best and usually succeeds, but her accomplishments are never enough for her mother to appreciate.
- Where da White Women At?: In "Hostile Takeover" it's revealed that she asked out Idris Elba. It's one of several "scandalous" things that were revealed about her after she got hacked. He turned her down, which she considers his loss.
- You Called Me "X"; It Must Be Serious: Cat pronounces Kara's name correctly in the final episode of Season 1, indicating she was no longer her subordinate.
Portrayed By: Peter Facinelli
Voiced By: Emmanuel Bernal (Latin-American Spanish dub), Takashi Kondo (Japanese dub)
First Appearance: "Stronger Together" (Supergirl 1x2)
A multimillionaire tech genius out to discover Supergirl's true identity.
- Ambiguous Situation: He is no longer enemies of Kara or the D.E.O. Did he become good or is he a Villain of Another Story? The two references he has had indicate he is alive, but his current moral status and what he is up to are unknown.
- And Starring: Is credited with "Special Guest Star" citation.
- Anti-Villain: He is kind of extreme, but he wants to make the world a better place. When his plans accidentally go too far, he feels remorse for it.
- Asshole Victim: It is revealed that his laboratory was destroyed by Andrea Rojas. While not evil, he still is still too callous to be sympathetic.
- Bad Boss: Played with. First, he fires the lead engineer on the maglev train project for not coming up with a way to increase the trains speed, instead of just telling him the method Lord himself came up with. Then, when Reactron tries to capture one of his scientists, he offers himself instead, putting him at risk. But the reason he states for this is because he is so much better than the other guy, making the whole thing possibly just an egotistic act to get himself into the spotlight. Cemented when his ex-employee Knox reveals Lord blackmailed him into planting bombs to test Supergirl in exchange for a too expensive medical treatment for his daughter, which leads to Knox's suicide.
- Big Bad Ensemble: Seemed to have become this alongside Astra's forces in "Blood Bonds". Seemed to have performed a HeelFace Turn, though later actions subverted that.
- Big Bad Wannabe: Isn't as much of a threat as Myriad, even helping to stop the Kryptonians' plans.
- Captain Ersatz: Of Lex Luthor. In addition to being an Insufferable Genius and billionaire industrialist, he dedicates his spare time to smearing the superhero of the city, and crafting nefarious plots. There's a scene where Supergirl confronts him in a very similar way to how Lex was confronted by Superman in previous series. Also like Luthor he creates an Evil Knockoff of the Kryptonian. Doubles as a Mythology Gag to the comics, where for the first few arcs of Justice League International Lord was the rich and powerful human agent for a rogue A.I. before switching sides. What did Lord use to create his Evil Knockoff here? DNA residue from part of a rogue A.I.
- Chuck Cunningham Syndrome: He disappears from the series without any explanation after Season 1. Made even more obvious with the arrival of Lena Luthor who takes on the same role Maxwell did in Season 1 (ultra-rich business tycoon-turned-inventor-turned-philanthropist whose positioning in the Right vs Wrong scale is initially unclear and who engages in a romance with one of the lead characters).
- Composite Character: Both of Lex Luthor and himself in and out of story, naturally. His distrusting of superpowers (Supergirl in general) coupling in his Crooked Contractor motif are dead giveaway's.
- Deadpan Snarker: He has a crass remark ready for every situation.
- Freudian Excuse: He hates the government for the death of his parents who worked as government scientists, which they covered up. As a result, he doesn't trust anybody but himself. This is a big part of the reason he doesn't like Supergirl: he says that superheroes make people complacent, and that ordinary people should rely on themselves.
- Hollywood Atheist: "If there was a God, She never would have put us in this mess."
- Hot Scientist: Max Lord is a brilliant physicist and is very handsome. Cat calls him sexy despite not being fond of him.
- Iconic Outfit: While Lord wears a variety of clothes, they tend to be typical formal men's wear, but with one notable, Rule of Symbolism exception-he never wears a necktie as a sort of way of keeping him more youthful and progressive seeming.
- Insufferable Genius: The man is a technological genius and he will not let you forget it. Alex derogatorily referred to him as nothing more than "A reformed nerd with a God Complex."
- Jerkass: Lord is a dick on general principle, but seems to dislike Supergirl in particular, even calling her a "pet alien" to her sister.
- Jerkass Has a Point: When he was apprehended by Alex and her agents from the DEO and locked away in an cell for what would be for years, he was valid when he mentioned they didn't have enough evidence or lawful clearance to arrest him let alone lock him away with no due process or trial.
- Jerk with a Heart of Gold: Dick though he may be to the point Kara refers to him as a monster, Lord does seem to genuinely want to make the world a better place.
- Lonely at the Top: Due to his distrust in people.
- Meaningful Name: He wishes to lord over humanity and he definitely has a God complex.
- Not Me This Time: Played straight with the Black Mercy. Zig-zagged with the Red Kryptonite, as he admitted to creating it, but intended it to affect Non rather than Supergirl, and definitely did not intend it to turn Kryptonians into uninhibited jerkasses, just to act like regular green kryptonite.
- Perma-Stubble: He has a short beard. J'onn mocks it once while impersonating him.
- Second Episode Introduction: Introduced in the second episode of the entire series.
- Secret Keeper: He has not outed Kara as Supergirl after discovering her identity.
- Sharp-Dressed Man: He's not seen without a suit.
- Ship Tease: He showed an interest in Alex which eventually lead to a date, but his antagonism towards Kara made their relationship mostly one-sided and she only went on a date with him and faked interest in him to get information. Though she was shown to care about him somewhat when she tried to encourage his good side and even held his hand when it seemed like the world was about to end.
- With Cat as they had a past relationship and later he goes out of his way to send her jewelry made out of a material that made her immune to the Kryptonian mind control device.
- Took a Level in Jerkass: While he was a jerkass from the very beginning, he still possessed quite a few positive qualities. These are less and less on display as Season One goes on, and by "Bizarro" he's graduated into a true supervillain willing to target Supergirl in her civilian identity.
- Subverted, as he then begins to gain back his positive qualities, or at least stops being as direct of a supervillain. Probably by recognizing, well... he doesn't want to pass Kara's Godzilla Threshold. He also helps out against Non and company as things get hot.
- Ungrateful Bastard: Kara rescues him from Reactron, but he intentionally robs her of the credit.
- Villainous Crush: Towards Alex Danvers. But following the Kryptonian attack at his company, he tells Alex their partnership is over. He still has dinner with her at one point, though both are trying to get information out of the other.
- Villain with Good Publicity:
- He orchestrated the bombing campaign against his own company in "How Does She Do It?" and blackmailed his patsy with a life saving surgery for the man's daughter, all to analyze Supergirl's powers.
- In "Human for a Day", he is quick to take advantage of the earthquake to boost his own PR and take shots at Supergirl, while also doing genuinely good deeds.
- What Happened to the Mouse?: Disappears without explanations and has had only two mentions, despite being set-up as a major player during the Season 1 finale. Lena Luthor has been inserted in his place as a sort of distaff Suspiciously Similar Substitute. We learn in Season 5 that his company was decimated by Andrea Rojas, but what happened to him personally is still a mystery.
Portrayed By: Tristin Mays
First Appearance: "How Does She Do It?" (Supergirl 1x4)
Maxwell Lord's personal assistant.
- Alliterative Name: Paulina Parker.
- Girl Friday: Fills this role for Maxwell Lord.
- Punch-Clock Villain: It's clear she's not a bad person, she's just doing her job.
- Satellite Character: All that's really known about her is that she's Maxwell's secretary.
- Token Good Teammate: Played with. While she's not evil, she doesn't really question the moral implications of what Lord does.
Species: Human (Enhanced via technology)
Portrayed By: Rahul Kohli
First Appearance: "Ace Reporter" (Supergirl 2x18)
Lena Luthor's ex-boyfriend and the billionaire CEO of Spheerical Industries.
- Adaptational Heroism: In his only comics appearance, Jack Spheer was a Corrupt Corporate Executive who who used the mind-control powers he'd gained from the Biomax formula to get revenge on The Power Company's Joshua Powers. Here, he's the one '''being''' mind-controlled.
- Brainwashed and Crazy: He has been programmed to kill by Beth after his Biomax "bees" downplay his will.
- Celebrity Paradox: iZombie was mentioned on The Flash (2014) Season 2, even though his actor is one of the main characters there. And unlike other examples, the paradox couldn't be subverted since Barry himself traveled to this universe (twice).
- Decomposite Character: His villainous role was given to his secretary.
- Hot Scientist: He is good-looking and the owner of a research laboratory.
- Rogues Gallery Transplant: Jack Spheer was a Green Arrow villain originally, not a Superman or Supergirl one. Apparently there is no hero with the "Green Arrow" mantle in Earth-38.
- Tall, Dark, and Handsome: He is taller than Lena, dark-haired and handsome.

Portrayed By: Floriana Lima
Voiced By: Jahel Morga (Latin-American Spanish dub)

A detective for the National City Police Department who takes a special interest in the cases involving aliens.
- Action Girl: Moreso than the comic Maggie.
- Adaptation Dye-Job: She's blonde in the comics. Here, she's played by a brunette actress.
- Advertised Extra: Her actress' name is included in the OBB, but she's mainly a Satellite Love Interest to Alex.
- Aloof Dark-Haired Girl: When on the job, she's stoically committed to the shield. After hours however she can be playful, flirtatious and fun, but even still keeps somewhat an emotional distance from most. Until Alex came along, that is.
- Amazon Chaser: Just look at her reaction to Alex punching Richard Malverne, the man who kidnapped and threatened her life in "Alex".
- Ambiguously Brown: Invoked by Maggie, who only refers to herself as "non-white".note However, as her dad is shown to be Mexican-American later, Maggie could be considered a Latina (though she never identifies herself as such).
- Battle Couple: With Alex. Even before they started dating, they fought together, with Maggie even remarking that they make a good team. After they get together, they don't get to show this off until "Exodus", when they first fight CADMUS agents in the alien bar together and then, when Alex goes rogue after being suspended from the DEO, fight CADMUS agents and rescue deported aliens together.
- Biker Babe: She mentions that she owns a motorcycle, plus her wardrobe of leather jackets is reminiscent of this archetype.
- Birds of a Feather: With Alex. Both are tough, intelligent women who even have the same interests in music (e.g., Barenaked Ladies).
- Child Hater: Downplayed, she doesn't hate children by a long shot, but she just doesn't see herself as a mom, unknowingly putting her at odds with Alex who wants to be.
- Closet Key: For Alex. After Maggie's girlfriend breaks up with her, Alex is persistent in wanting to spend time with her which makes Maggie wonder if Alex herself is gay. This question makes Alex strongly consider the possibility that she is. Other than that it is clearly shown that Alex may be developing feelings for her through the fact that they have common interests and personalities.
- Composite Character: Maggie's namesake counterpart in the Superman mythos is a no-nonsense short-haired blonde woman, while this version (long-haired sarcastic brunette with a willingness to bend the rules) has more in common with Renee Montoya from the Batman comics.
- Cowboy Cop: Unlike comic "by the book cop" Maggie, this Maggie Sawyer works outside the law to aid her in her cases, and her way of dealing with tense situations are straight out of an action movie. She also enjoys engaging in Casual Danger Dialogue.
- Dark and Troubled Past: Maggie reveals in "Mr. and Mrs. Mxyzptlk" that she lied about her parents being okay with her homosexuality. They kicked her out of the house when she was 14, and she was forced to live at her aunt's for three years.
- Fair Cop: Maggie is a very attractive police officer and gets her fair share of attention from females of many species, Alex included.
- First Love: She is this to Alex as she is the first person that Alex has had strong feelings for, as it was noted that her past relationships never got very far due to her lack of attraction to men.
- Forced Out of the Closet: She was outed as a lesbian when she was 14, at which her parents disowned her.
- Freudian Excuse: She was outed at 14 by a girl she liked on Valentine's Day. Her parents then kicked her out and she moved in with her aunt. This is the reason behind her extreme dislike of the holiday.

- I Want My Beloved to Be Happy: Realizing that Alex's dreams are too important for her to sacrifice, she gracefully bows out of their engagement, assuring Alex she's going to be an amazing mother someday.
- Lipstick Lesbian: Maggie's a tough cop who falls in the "chapstick" category (she has long hair, but also more masculine clothing and a somewhat tomboyish manner, but not enough for "butch" either). She had an alien ex-girlfriend who learned English by tongue contact.
- Manic Pixie Dream Girl: To Alex. Her presence is one of the few things that can get the guarded and emotionally closed-off Alex to lighten up, not to mention Maggie helped Alex realize she was a lesbian.
- Nephewism: She mentions that she came to live with her aunt after her parents kicked her out when she'd been outed to them.
- Only Known by Their Nickname: Her full first name is Margarita, though she's always called Maggie.
- Put on a Bus: She departs the series in Season 3, leading to an amicable breakup with Alex.
- Race Lift: Maggie is now explicitly non-white, played by actress Floriana Lima (who's said she has Italian, Irish, English, Spanish and Portuguese ancestors). Later her dad is shown to be Mexican-American, and thus she could be considered a Latina (though Maggie doesn't identify herself that way).
- Satellite Love Interest: She barely had a role outside of being Alex's girlfriend.
- Secret Keeper: In the know that Kara is Supergirl, Clark is Superman, Mon-El is from Daxam and James is Guardian.
- Ship Tease: With Alex that eventually leads to Maggie confessing her feelings to her and them hooking up at Alex's apartment.
- Trademark Favorite Food: Discussed by Alex.Alex: (to Kara) And, oh, she loves tiramisu. I mean, could eat it for every meal, literally. It's like her happy food.
- Twofer Token Minority: Invoked by Maggie when she talks about growing up in Nebraska as a non-white lesbian. Specifically, she's Mexican-American.
- Two First Names: "Sawyer" can also be a first name.
- Workaholic: According to an ex-girlfriend, she broke up with Maggie partly because of this. (This seems to be an Informed Flaw, however, since Alex seems to be the workaholic of the two.)

- Adaptation Name Change: In the comics, Cat's son is named Adam Morgan. It is then revealed that they're a Decomposite Character.
- Ambiguous Disorder: Emphasis on Ambiguous; Cat stresses to Kara that Carter is "special," and his shyness and poor impulse control could imply that he's on the Autism Spectrum.

First Appearance: "Man of Steel" (Supergirl 4x3)
The owner of Lockwood Family Steel and the father of Ben Lockwood / Agent Liberty.

- Driven to Suicide: Well he thinks this — blaming aliens for his business going under and purposefully waiting in his refinery to die during the Daughters of Juru' terraforming rather than acknowledge that he let his sense of Pride cloud his business judgement.
- Family Business: He used to own a steel factory. It ran out of business due to his customers switching to the alien Nth Metal, which further fueled his hate; he could've modernized it to stay afloat but he refused.

- Jerk with a Heart of Gold: Outside of his prejudice against aliens, he was a Benevolent Boss, a good parent, and a doting grandparent.
