[=CatCo=]'s former art director, whom Kara had a crush on. He becomes [=CatCo's=] CEO when Cat decides to take a long, possibly permanent, sabbatical. After growing listless of seeing Kara save the city, especially with her cousin, James decided to get into the crime-fighting business himself; using armor created by Winn, he became a vigilante under the code name "Guardian".

----
* AdaptationalAttractiveness: Though the original Jimmy isn't exactly unattractive, he was a nerd as opposed to the show's "alpha male."
* AdaptationalBadass: While the original Jimmy Olsen was no pushover, this version is a skilled combatant and a top athlete. Who with only a suit of [[LuckilyMyShieldWillProtectMe armor and shield takes to crime fighting]] with surprising ease.
* AdaptationalCurves: Jimmy Olsen is mostly depicted with GeekPhysiques or at least average built. This one is an obvious {{Hunk}}, though it is possible that he used to be BlackAndNerdy when he was at the Daily Planet and just beefed-up since. After all, he ''is'' mostly depicted as a nerd in Superman's story.
* AdaptationDyeJob: A redhead in the comics, this Jimmy is [[BaldOfAwesome bald]], and has black hair otherwise.
* {{Adorkable}}: Downplayed due to his OlderAndWiser, but still there. He still wears the Signal Watch, among other things. He also named Reactron.
* AntiHero: He is TheCowl to Kara's TheCape, similar to the dynamic Batman and Superman share in the comics. He is willing to threaten and rough people up while questioning them, among other things.
* AttackReflector: Guardians Shield reflected [[PowerParasite Parasite's]] punch in Season 2 Episode 6.
* BadassBaritone: James's already deep voice is electronically lowered as Guardian.
* BadassNormal: He's got a black belt, and is more than capable of defending himself even without powers.
* BaldBlackLeaderGuy: After Cat Grant appoints him as her replacement as [[IncrediblyLamePun head]] of [=CatCo=].
* BashBrothers: With Winn since becoming Guardian.
* BenevolentBoss: In Season 2, becomes Cat's successor at [=CatCo=]. He offers to strong arm Snapper for Kara into letting her work, but at that point, Kara is determined to earn her reporter job.
* BettyAndVeronica: He's the TallDarkAndHandsome {{Hunk}} (Veronica) contrasting Winn's {{Adorkable}} {{Nerd}} (Betty).
* {{Bromance}}: He and Clark are really close. Lucy even admitted to being jealous over him constantly spending more time with him (or rather, Superman).
** He also develops one with Winn.
* CameraFiend: Made his name as a photographer, though now his current position is art director.
* CharacterDevelopment: [[FlatCharacter Initially seemed only to exist]] as [[SatelliteLoveInterest the handsome hunk for Kara to swoon over]], and a constant reminder that Superman is a thing. Come season 2 and his taking over of [=CatCo=] [[YouAreInCommandNow in Cat's stead]], and taking it to the streets as [[VigilanteMan The Guardian]] fleshes out his character considerably. Season 3 builds on this with his friendly rivalry with Lena, the new owner of the media conglomerate, and his [[BelligerentSexualTension slight flirting]] with her at the same time is the far cry from the rather bland photographer we were introduced to in the pilot.
* CompositeCharacter: In the comics, the black headstrong journalist who has a thing with Lucy Lane although her father kinda hates him is Ron Troupe. Though Jimmy ''did'' have a crush on Lucy. He's also this universe's version of Guardian.
* TheCowl: Deconstructed in "City of Lost Children", he became [[VigilanteMan The Guardian]] to protect people and bring them hope like [[TheCape Superman and Supergirl]] but unlike them to everyone else he's just a scary guy in a mask who runs out and attacks people; he desperately wants to avert this image.
* CursedWithAwesome: In a way, how he views his relationship with Superman. He loves their friendship, but is bothered by how others look at him solely for knowing Superman rather than judging him on his own merits.
* {{Determinator}}: The guy will not back down from a fight, even when the odds are against him.
* DudeWheresMyRespect: In Season 3, once Lena takes direct control of [=CatCo=], and she starts making decisions without his input or consultation which results in friction between the two.
* EasilyForgiven: Once National City learns of Phillip Karnowsky's actions, Guardian is instantly forgiven by the city. It helps that Guardian isn't burdened with BewareTheSuperman.
* EmbarrassingNickname: He's best known as "Jimmy Olsen," the name he used when he took a Pulitzer-winning photo of Superman, but now insists on being called "James."
* FlatCharacter: In season one, before gaining a much more rounded personality outside of his connection with the cousins from Krypton, see CharacterDevelopment.
%%* FourTemperamentEnsemble: Phlegmatic
* GreenEyedEpiphany: He quickly grows jealous of how well Barry Allen gets on with Kara. This is what ultimately motivates him to confess his feelings to her.
* HeroWithBadPublicity: Briefly when National City thinks he's responsible for the murders by Phillip Karnowsky. It lasts one episode before he's vindicated.
* HugeGuyTinyGirl: Mehcad Brooks is a whole foot taller than Lucy's actor, Jenna Dewan (6'3" vs 5'3")
* IconicItem: As James, it's the camera his father gave him; he's always on the scene, putting himself in danger to make sure people see the truth. As Guardian, it's his shield; he doesn't carry a weapon, he's just there to defend people.
* InNameOnly: He looks and acts nothing like the Jimmy Olsen from the comics. In fact, he is more the exact opposite of the original character, with Winn being a better match for the traditional Jimmy Olsen.
* InsistentTerminology: He now prefers James to Jimmy, his sobriquet at the Daily Planet.
* KickedUpstairs: He admits that being promoted is boring him because he enjoys working on the field more.
* LuckilyMyShieldWillProtectMe: As Guardian, he has a shield.
* LooseLips: He accidentally slips Clark's SecretIdentity to Winn.
* MayDecemberRomance: Kara is more or less two decades older than him, but her being stuck in the Phantom Zone stalled her youth.
* MilitaryBrat: His late father was in the military. He never specified which branch, though (only implied to be either Army or Marines).
* OlderAndWiser: Jimmy is usually depicted as TheChewToy and ButtMonkey of the ''Daily Planet''. If he was in this series, that was in his younger days. James is now portrayed as more confident and poised.
* OnlyKnownByHisNickname: {{Inverted|Trope}}. He's known by his real name, "James," rather than his more famous nickname, "Jimmy" (by everyone but his mother and "[[ComicBook/{{Superman}} the big guy]]").
* OutOfFocus: With a bigger emphasis on Kara and Winn's work with the DEO and the introduction of [[ShipTease Mon-El]], James slowly fades out of the spot light, and would've ended in complete obscurity, had it not been for him taking the mantle of "Guardian." Even at that, there have been episodes where James gets into his Guardian suit, throws one punch or receives one, and then is never seen again the rest of the episode.
** Somewhat justified as Mechad Brooks has informed the writers that if he gets offered the right script, he may end his contract and leave the show.
* RaceLift:
** Practically Everything Lift. James is an older, taller, suave bald black man, whereas Jimmy's traditionally a YoungerThanTheyLook, red-headed, short nerdy white man. Practically the universal reaction to fans to finding out he is Jimmy Olsen is "THAT'S JIMMY?!"
** A two-fer as James takes on the role of Guardian, normally played by white Jim Harper.
* SecretKeeper: Knows both Superman's and Supergirl's secret identities.
* SecretSecretKeeper: Superman told James about his cousin and requested that he keep an eye on her when he moved to National City. It doesn't take long for him to come out with this to Kara.
* ShoutOut: Guardian shares a lot in common with ComicBook/{{Steel}}.
* {{Sidekick}}: {{Deconstructed}} in "Crossfire", when he moans that he's always been TheCape's sidekick, and he wants to be the hero now. He becomes one the very next episode.
* ThouShaltNotKill: Guardian refuses to kill, which is strongly hinted as the main reason the National City populace tolerates him.
* TookALevelInBadass: Technically Jimmy's always been a badass (it falters at times DependingOnTheWriter), but due to the fact that both he and Superman have had a decade of experience, James is a much more seasoned pro in conflict. In "Crossfire", he shows off some impressive GoodOldFisticuffs, while the next episode sees him become a vigilante.
* TheUnmasking: [[spoiler: He reveals his identity to the public in the Season 3 finale.]]
* VigilanteMan: As the Guardian, he takes care of problems that Kara and the DEO may not have the time for.
* VoiceWithAnInternetConnection: Works as this alongside Winslow when Supergirl is doing more public non-DEO acts of heroism.
* YouAreInCommandNow:
** Cat appoints him as the new head of [=CatCo=] in her sabbatical.
** Lena also allows him to oversee the running of [=CatCo=] while she takes a hands on approach in the bullpen.

[[folder:Eve Teschmacher]]
!!Eve Teschmacher
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/et_6.png]]
!!! '''Species:''' Human
!!! '''Portrayed By:''' Andrea Brooks
!!! '''Voiced By:''' Creator/MonicaManjarrez (Latin-American Spanish dub)
!!! '''Appearances:''' ''Series/{{Supergirl|2015}}'' | ''Series/{{The Flash|2014}}''

Cat's new assistant at the beginning of Season 2.
----
* AdaptationalHeroism: She's Lex Luthor's secretary in her source material. Here, she works for Cat Grant briefly, then becomes James's assistant.
* AdaptationDyeJob: Downplayed. While the character is blonde in her source material, Valerie Perrine's version had dirty blonde hair while Andrea Brooks's is golden blonde.
* AgeLift: Valerie Perrine was 34/35 when she played the role in Creator/RichardDonner's first ''Film/{{Superman}}'' movie, while Andrea Brooks was 27 when she played this version. And even if DawsonCasting is at play in both cases, Perrine's version is clearly at least in her late 20s.
* AlmightyJanitor: Studied Nuclear Physics at Yale, yet she seems perfectly content working as personal assistant at [=CatCo=].
* BeleagueredAssistant: She didn't ''quite'' adjust to Cat Grant. James and Lena are less demanding.
* TheCameo: She makes a quite surprising appearance on ''The Flash'' when working late in Jame's office one night she is wintess to a battle between two Vibe powered individuals before both vanish as quickly as they came.
-->'''Eve''': Is it just me or is [[LampshadeHanging this city getting weirder!?!]]
* CanonImmigrant: From the Creator/ChristopherReeve ''Film/{{Superman}}'' movies. She never existed in the comics before then.
* TheCutie: Good-looking, adorable, and upbeat.
* HiddenDepths: To be inferred, since Cat Grant has an amazing eye for talent. If she didn't, she'd have been fired already. Turns out also that she's a scientist who graduated from Yale.
* MayDecemberRomance: She has a thing with Mon-El for a while, who is chronologically older than her by more or less three decades, but him traveling a time locked section of the universe stalled his youth.
* NewMeat: She's Kara's replacement intern introduced in Season 2.
* NiceGirl: Chipper and sweet to just about everyone, plus she is openly friendly with Kara, even after discovering her crush "Mike" had feelings for her and vice-versa, and often takes Cat's demands in stride.
* NotWhatItLooksLike: Eve lamely invokes the trope verbatim when she and Mike are caught half-undressed and making out, her legs wrapped around him.
-->'''Kara:''' This is ''the definition'' of something being what it looks like!
* PhraseCatcher: "'''''MISS TESCHMACHER!!!'''''"
* ShipperOnDeck: After picking up that Mon-El and Kara have feelings for each other, she subtly gives Kara a nudge to act upon them.

[[folder:Snapper Carr]]
!!Snapper Carr
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/sc_9.png]]
!!! '''Species:''' Human
!!! '''Portrayed By:''' Ian Gomez
!!! '''Voiced By:''' Dafnis Fernández (Latin-American Spanish dub)
!!! '''Appearances:''' ''Series/{{Supergirl|2015}}''

A veteran newsman hired by Cat Grant to be the editor-in-chief of [=CatCo=] magazine.
----
* AdaptationDeviation: Snapper Carr was a non-powered member of the Franchise/JusticeLeagueOfAmerica, and generally the mascot of the group. He's in a position of authority in this show.
* AdaptationalUgliness: While cute and young in the comics, is a balding middle aged man here.
* AgeLift: Like Cat, a good twenty years older than his original comic incarnation.
* AmbiguouslyJewish: Snapper quotes a Yiddish phrase told to him by his grandmother.
* AndStarring: Gets this citation in the guest stars lineup.
* BerserkButton: In "Exodus", you finally get to see what Snapper looks like when ''angry'' after [[spoiler:Kara publishes a story independently]]. He drops the DeadpanSnarker facade and shows his real emotions, and you finally see the real Snapper.
* BrutalHonesty: He may not care if you enjoy hearing it, but he'll give it straight - at least when it comes to his profession.
* CompositeCharacter: Snapper's personality is more akin to Perry White's.
* DaEditor: 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
* GutturalGrowler: Speaks with a very rough, deep voice, compared to his actor's much normal voice.
* IntrepidReporter: 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.
* JerkassHasAPoint:
** 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 {{Website/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.
* {{Irony}}:
** The comics version of Snapper Carr was a friendly, handsome young man and a deep friend to the Justice League. This Snapper Carr is pretty much his reverse, being a sharp-tempered, cynical, plain-featured older man who serves more of an antagonistic role.
** 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 ByTheBook attitude regarding the rules of journalism preventing Kara from exploiting her secret identity to aid her own status as a reporter, ala [[ComicBook/SpiderMan Peter Parker]] or classic depictions of her cousin [[ComicBook/SuperMan 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.
* JerkWithAHeartOfGold: Hostile towards Kara, though for admittedly good reasons. She's a rookie reporter and [[StealthMentor 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.
* MeanBoss: 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.
* MeaningfulName: 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.
* MustHaveCaffeine: Snapper's definitely ''not'' a morning person: priorities are coffee and danish first thing, that's it.
* PutOnABus: It's mentioned that he has gone on sabbatical from [=CatCo=] in "Girl of Steel".
* ReasonableAuthorityFigure: 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," [[StealthMentor 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.
* SoProudOfYou:
** 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 -- [[DisappointedInYou as he's firing her]].
** In "Ace Reporter", he heaps on praise for her being TheDeterminator 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.

[[AC:Former Employees]]
[[folder:Cat Grant]]
!!Catherine "Cat" Grant
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/009_season2_promotional_copy1.jpg]]
!!! '''Species:''' Human
!!! '''Portrayed By:''' Calista Flockhart
!!! '''Voiced By:''' Creator/LilianaBarba (Latin-American Spanish dub), Creator/EriMiyajima (Japanese dub)
!!! '''Appearances:''' ''Series/{{Supergirl|2015}}''

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.
----
* AdaptationRelationshipOverhaul: Cat goes from antagonistic to Kara to a maternal mentor and steadfast ally of her.
* AdaptationalHeroism: She was an incredibly unapologetic AlphaBitch in the comic books (pre-''ComicBook/{{Flashpoint}}''), and her only interaction with that version of Supergirl was a mud-slinging campaign (brought upon because of Kara [[DisproportionateRetribution accidentally]] [[UngratefulBastard breaking her arm when saving her life]]) so brutal that Kara ''swore to never save her life again''. This version is a JerkWithAHeartOfGold that has no problem giving Kara a necessary pep-talk... [[MoodWhiplash and then order her to go get her a latte]]... or try to draw a super villain away from her employees.
* AdaptationalModesty: Cat Grant in the comics showed off her boobs, while Cat Grant in this series fully covers her torso and is never sexualized.
* AgeLift: 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, [[OlderThanTheyLook Calista doesn't look fifty]]. Considering she was revealed to have a son in his mid-twenties, she can't be that much younger.
* AndStarring: 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.
* AnimalMotif: She has been compared, obviously, to cats.
* BigBraToFill: PlayedWith. Cat is portrayed by the modestly endowed Calista Flockhart, but her comic counterpart has breast implants [[BigBreastpride which she]] [[TheTease regularly flaunts]].
* BrokenAce: Her competitive, "always go for the win" attitude is revealed to have been partially fueled by her mommy issues.
* CatSmile: Appropriately enough. Her actress is known for having this trait, which she does even in this show (see her page image).
* CelebrityParadox: ''Franchise/StarWars'' is acknowledged to exist in this universe despite the fact that her actress is married to [[Creator/HarrisonFord one of the lead actors]] of the franchise in RealLife. In "Myriad", there's a reference to the wife of [[Creator/HarrisonFord the aforementioned actor]], meaning it's possible that Cat and Calista Flockhart exist in the same universe.
* CharacterDevelopment: With Flockhart unable to continue the show, this had the effect of having Season 1 be a subplot of Cat Grant [[SlidingScaleOfIdealismVersusCynicism sliding from cynicism to idealism]] to the point at where she had the courage to ''completely'' re-prioritize and choose family over work. [[invoked]]
* ColdHam: She loves delivering her lines in a "theatrically subdued" manner. [[IncomingHam Unless]] she's calling someone, that is.
* DeadpanSnarker: When commenting on Kara's [[NiceJobBreakingItHero rough start as a hero]], she says "Oh, what is the opposite of super? #Terriblegirl?"
* DecompositeCharacter: The one to mock Supergirl is Leslie, not Cat.
* DefrostingIceQueen: To both Kara and Supergirl. How much of that is due to them living up to her ToughLove 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.
* DemotedToExtra: She was downgraded to a recurring role in Season 2, in a case of RealLifeWritesThePlot after the show's production moved to Vancouver, as Calista Flockhart is famously uncomfortable working outside Los Angeles. [[spoiler:Makes a cameo in the Season 3 premiere, where she is now the Press Secretary to President Marsden.]]
* DramaticIrony: Cat initially doesn't want to hire Kara because she doesn't like Millennials, not knowing that Kara is chronologically born in 1966, making her a member of Generation-X like Cat herself[[note]]Assuming that Cat is as old as her actress, then Kara is just two years younger[[/note]].
* EasilyForgiven: 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.
* EatingTheEyeCandy: Goes wide-eyed and flirtatious whenever Clark is around, and blatantly [[FemaleGaze admires]] his backside at one point.
* EveryoneHasStandards: She's unashamedly a cold and calculating media mogul, but she's genuinely impressed by Supergirl's status as a HopeBringer 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 [[Film/TheDevilWearsPrada 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 SerialNumbersFiledOff.
* FriendlyRivalry:
** 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 [[VitriolicBestFriends close friends.]]
* GoodIsNotNice: 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).
* GoodParents: 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 "[[AmbiguousDisorder 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.
* HopelessSuitor: She has a thing for Clark Kent and asks if her prediction that he and Lois break up came true.
* HorribleJudgeOfCharacter: 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.
* HypocriticalHeartwarming: 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.
* IncomingHam: You know she's about to enter the scene when she's calling for Kara from afar.
--> '''KYRA!'''
* ItsAllAboutMe: 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.
* JerkassHasAPoint:
** Though couched in an ItsAllAboutMe 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. [[{{Irony}} 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 ShooTheDog.
* JerkassBall: 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.
* JerkWithAHeartOfGold: "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 VillainOfTheWeek 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.
** Another good example is when Supergirl/Kara is under the influence of red kryptonite and decides to see if [[IncrediblyLamePun "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.
* KnightInSourArmor: 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 CrapsackWorld.[[note]]It's probably the reason why she clings to Supergirl so much.[[/note]]
* {{Malaproper}}: 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.
* MeanBoss: [[http://www.supergirl.tv/supergirl-monday-s-at-8pm-nov#comments TV Guide]] has described her as "A ''[[Literature/TheDevilWearsPrada Devil Wears Prada]]''-type boss." Almost fires Kara for suggesting "Superwoman" instead of "Supergirl," which she coined. Also, [[ArsonMurderAndJaywalking she consistently mispronounces Kara's name]].
* MyGreatestFailure: 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.
* NoCelebritiesWereHarmed: Described as "[[Music/JenniferLopez J. Lo]] by way of Anna Wintour" in casting calls.
* OlderThanTheyLook: 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.
* OneSteveLimit: She and her mother share the same name aside from a different letter at the very beginning.
* ParentalSubstitute: To Kara, of the ToughLove 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.
* PutOnABus: Decides to leave [=CatCo=] in the second episode of Season 2, due to Calista Flockhart's established refusal to work outside of Los Angeles.
* RedBaron: She's known as "The Queen of all Media". Doubles as her BadassBoast.
* SecretKeeper:
** 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 SecretSecretKeeper.
** 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 NiceGuy.
** Averted with James as Guardian, as she immediately tells Clark about this.
* SelfMadeWoman: 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.
* SerialSpouse: 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.
* SilkHidingSteel: At first glance you'd think she's a comical DirtyCoward, but she's actually pretty brave as she doesn't hesitate snarking at her now superpowered ex-protegee more than once.
* SingleWomanSeeksGoodMan: As with the comics, Cat carries a torch for Clark, partly due to his Midwestern looks and values.
* SitcomArchNemesis: Her relationship with Lois Lane in a nutshell, since Cat rarely goes for a whole episode without saying something nasty or competitive about Lois.
* SoProudOfYou: 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, ''[[SecretSecretKeeper Supergirl]]''!
* SpottingTheThread: Cat is very observant, spotting even the smallest details about something or someone. She even easily figures out that Kara's, James's, and Barry's alter egos.
* StartMyOwn: She apparently got fed up with being a worker at the Daily Planet, so she started her own company.
* StealthMentor: Her scoldings and lectures (see JerkassHasAPoint) actually contribute to Kara's CharacterDevelopment, 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.
* {{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 [[BlatantLies not feeling guilty about what happened to her]]. She is also quite sweet to her son Carter.
* TranquilFury: 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.
* TwoFirstNames: Per the Creator/DCComics norm.
* VitriolicBestFriends: The reasoning 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 [[FriendlyRival rivalry]].
* WeirdnessMagnet: 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.
* WellDoneDaughterGal: 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.
* WhereDaWhiteWomenAt: In "Hostile Takeover" it's revealed that she asked out Creator/IdrisElba. 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.
* YouCalledMeXItMustBeSerious: Cat pronounces Kara's name correctly in the final episode of Season 1, indicating she was no longer her subordinate.

!!Lena Kieran Luthor
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/spg201a_0042b.jpg]]
!!! '''Species:''' Human
!!! '''Portrayed By''': Creator/KatieMcGrath
!!! '''Appearances:''' ''Series/{{Supergirl|2015}}''

Younger half-sister of ComicBook/LexLuthor, who is now the head of Luthor Corp/L Corp after his incarceration. She bought [=CatCo=] in Season 3.
----
* ActionGirl: At least, she's not a NeutralFemale. She will fight back, even if she's overmatched.
* AdaptationDyeJob: She's blond (or a redhead) in the comics but on the show she has [[RavenHairIvorySkin very dark hair]].
* AlliterativeFamily: With her brother '''L'''ex, father '''L'''ionel and mother '''L'''illian.
* AlliterativeName: '''L'''ena '''L'''uthor.
* AloofDarkHairedGirl: She gives off this demeanor at first, but it doesn't make her a villain.
* TheAtoner: She repeatedly states that one of her goals is to undo some of the damage Lex (and, later, her mother) did to the Luthor name.
* BrainyBrunette: Raven-haired and the head of Luthor Corp. And, in one episode, she teams up with Winn to save the day.
* BenevolentBoss:
** Of L Corp. Is very kind to her employees and takes a hands on approach in ensuring their productivity and moral remains high.
** Also of [=CatCo=] after buying it: When Kara repeatedly blows off work to focus on being Supergirl full time, Lena immediately picks up that something is wrong and tries to get Kara to tell her what's going on. Though she has no issue dialing up the "Boss" part when Kara refuses to talk about it and insists on focusing on work, pointing out that Kara's behavior is unacceptable for an employee.
* BigBrotherWorship: Before he went all crazed evil overlord, Lena admits she loved and admired Lex.
* BlackAndWhiteMorality: In Lena's eyes, you are either truly good or irredeemably bad, no middle ground. Even if someone she considers good uses less than squeaky clean methods, she will find the intentions justified. However, if anyone dares to lie to Lena or betray her trust, they will be no chance of RebuiltPedestal for the transgressor in question.
* DaddysGirl: According to Lillian, Lena was her father's favorite child.
* FakeDefector: She pretends to side with Lillian in "Medusa", giving her the rare isotope needed to disperse the Medusa virus over National City. But it is later revealed that she sabotaged the isotope, making it useless, and calls the police on her mother.
* FriendlessBackground: Strongly implied to have one due to her family's bad reputation and her comments about always being alone on holidays.
* GadgeteerGenius: Can hotwire and invent high-tech equipment on the fly at speeds rivaling Winn's.
* GoodAllAlong: Given that her name is Luthor, and her mother is as crazy as her brother, the series spends a lot of the first half of Season 2 teasing that Lena might be a villain, complete with an apparent FaceHeelTurn that ends up being a BatmanGambit on her part. By the second half of Season 2 it's firmly established that she's not only a good guy, but well on the way to becoming Kara's best friend.
* GoodIsNotSoft: She may be on the heroes' side, but still doesn't hesitate to gun down the man who tried to kill her, which would have killed him if Cadmus hadn't gotten to him; in Season 3, she engages in a brief debate over gun ownership and states flatly that she has used a gun in self-defence. In a later episode she doesn't hesitate to help Supergirl by attempting hand to hand combat with someone who makes a BadassBoast of being a black belt (and holding her own).
** When confronting Morgan Edge [[spoiler: over [[WouldHurtAChild endangering the lives of children]] just to frame her and her lead bomb,]] she holsters a gun on him, [[spoiler: and express her belief that anyone so vile deserves to die.]]
** Later, when she learns that Edge is going to be murdered [[spoiler: by her mother]], she later realizes that just because she has the same ability as her brother and mother when it comes to being TheChessmaster doesn't mean she has to do it the same way. [[spoiler: So she does arrange to save Edge's life but uses the attempt to get a confession out of him.]]
* HappilyAdopted: Slightly averted, she did love and was loved by Lionel and Lex growing up, but [[WellDoneDaughterGal craved approval and affection]] from Lillian. In the end completely averted, when Lillian reveals she is indeed a biological Luthor all along.
* HeroicBastard: She is the illegitimate biological daughter of Lionel Luthor and his long time mistress, while at the same time being the most upright member of the family.
* HotScientist: Along with being exceptionally beautiful, she is a verified tech genius, and once was involved in researching nanotechnology.
* IAmNotMyFather: If there were any questions about Lena's morals, they were answered when she foiled her mother's plan to kill all aliens with a virus. She has come close to uttering a variant of the trope - "I am not my brother" - on many occasions.
* IconicSequelCharacter: Doesn't appear in the show until its second season (and in the Series/{{Arrowverse}} until the fifth year).
* InTheBlood: Defied. Despite heavy teasing early on that she would be as evil as her brother, she's been adamantly against his criminal activities from the start, and a staunch ally of Supergirl's who works hard to redeem the company's good name.
* ItsAllMyFault: After many children of National City [[spoiler: begin to show signs similar to lead poisoning]], she doesn't deny or reflect blame that [[spoiler: her lead bomb used to repel the Daxamites]] could be the catalyst. Devastated, she offers a sincere and gripping apology to the public and almost steps down from L Corp and [=CatCo=].
* JumpingOffTheSlipperySlope: [[spoiler: In "Battles Lost and Won", she lied to Supergirl about giving Alura all of the Harun-El. She secretly kept some of it to experiment on.]]
* MoralityPet: For her brother, according to WordOfGod, something that's also been the case in the comics. It's subverted when he hires an assassin to kill her.
* NiceGirl: Lena is friendly, altruistic and affectionate, especially to people she becomes close to like Kara and Sam.
* NotSoDifferent: Like Lex, she has a really good knack at developing anti-Krypton technology; albeit she uses it to keep Reign at bay, but Supergirl is still disturbed by the implications. After Supergirl becomes a BrokenPedestal due to a breach of trust, Lena makes some very Lex-like comments about Supergirl's "superiority" to Kara.
* NonIdleRich: Instead of loafing about like a stereotypical heiress, she uses the vast Luthor fortune to fund many charities and philanthropy to make her family a force of good in the world. Even Rhea openly admires her dedication to "the little people."
* OddFriendship:
** She forms one with both [[SecretIdentity Kara Danvers and Supergirl]]. She even brings up how people wouldn't believe "a Super and a Luthor working together" in "Crossfire".
** She is also friendly with Winn, who to her is just a random tech geek, though they are nowhere near as close as she is with Kara, notwithstanding a bit of ShipTease during one of her first appearances where they join forces to help save the day.
* OnlyFriend: Increasingly views Kara (''not Supergirl'') as this. Later begins to see Samantha this way too.
* OohMeAccentsSlipping: Creator/KatieMcGrath is a good actress, but an awful FakeAmerican.
* PromotionToOpeningTitles: Starting in Season 3.
* RavenHairIvorySkin: Lena has very dark hair, which contrasts a lot with her pale skin.
* RedeemingReplacement: She succeeded her notoriously evil brother as head of her family's company.
* RedemptionQuest: She is working hard to restore her family's reputation and reinvent their corporation after her brother's shenanigans. Her first step is renaming the company L-Corp.
* TheReveal:
** The Cadmus Lead Scientist is revealed to be her mother.
** She herself is revealed to be an illegitimate child of Lionel, making her a biological Luthor after all.
* TheRichHaveWhiteStuff: Lena's entire office, right down to the knick-knacks barely in shot.
* SiblingYinYang: The evil Lex Luthor's more benevolent sister.
* SinsOfOurFathers: She and her family receive backlash from Lex's actions, including from some of the main characters.
* SmartPeoplePlayChess: Which [[TheChessmaster makes her loyalties ''really'' suspect]], even though she's definitely not on her ''mother's'' side.
-->'''Young Lena:''' ''(beating a young Lex)'' I ''like'' this game.\\
'''Lillian:''' You ''are'' a Luthor.
* StrongFamilyResemblance: Flashbacks to her childhood in "Luthors" show that Lena and Lex looked a lot alike. Lillian admits that Lena also greatly resembles her birth mother (which was one of the major factors for her cold treatment of Lena).
* SuspiciouslySimilarSubstitute: Although she is a unique character in her own right, Lena is also in many ways a female version of Maxwell Lord, who [[ChuckCunninghamSyndrome disappeared without explanation]] between the first two seasons.
* TokenGoodTeammate: To the Luthor family since her half-brother and stepmother are both {{Card Carrying Villain}}s, while her father was AmbiguouslyEvil.
* TheUnfavorite: Lillian always favored Lex and barely tolerated Lena, a fact that Lena is well aware of and Lillian openly acknowledges this to be true, though according to Lillian, Lena was [[DaddysGirl Lionel's favorite.]]
* WeUsedToBeFriends: She no longer considers Supergirl her friend after she asked James to break into her lab to see if she had anymore Kryptonite. Supergirl ''wants'' to be still friends, but Lena point-blank refuses.
* WellDoneDaughterGal: Lena has tried her whole life to please Lillian, but there are lines she won't cross.
* WhiteSheep: Her half-brother is Lex Luthor. Her mother is the head of Cadmus. (As for Daddy, we don't get to know this version of Lionel.) Morals must not run in the Luthor family. But she is benevolent enough to count Kara as her OnlyFriend.
* YouAreInCommandNow: Takes over Luthor Corp after Lex is put in jail, striving to make it a force for good and rebranding it L Corp in an attempt to distance it from the stigma surrounding her family's name.

!!! '''Voiced By:''' Emmanuel Bernal (Latin-American Spanish dub), Creator/TakashiKondo (Japanese dub)
!!! '''Appearances:''' ''Series/{{Supergirl|2015}}''

A multimillionaire tech genius out to discover Supergirl's true identity.
----
* AmbiguousSituation: He is no longer enemies of Kara or the D.E.O.. Did he become good or is he a VillainOfAnotherStory? The two references he has had indicate he is alive, but his current moral status is unknown.
* AndStarring: Is credited with "Special Guest Star" citation.
* AntiVillain: He is kind of extreme, but he wants to make the world a better place.
* BadBoss: Played with. First, he fires the lead engineer on the maglev train project for not coming up with a way to increase the train’s 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.
* BigBadEnsemble: Seemed to have become this alongside Astra's forces in "Blood Bonds". Seemed to have performed a HeelFaceTurn, though later actions subverted that.
* CaptainErsatz: Of ComicBook/LexLuthor. In addition to being an InsufferableGenius 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 EvilKnockoff of the Kryptonian. Doubles as a MythologyGag 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 EvilKnockoff here? DNA residue from part of a rogue A.I.
* ChuckCunninghamSyndrome: 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).
* CompositeCharacter: Both of Lex Luthor and himself in and out of story, naturally. His distrusting of superpowers (Supergirl in general) coupling in his CrookedContractor motif are dead give away's.
* DeadpanSnarker: He has a crass remark ready for every situation.
* FreudianExcuse: 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.
* HollywoodAtheist: "If there was a God, She never would have put us in this mess."
* HotScientist: Max Lord is a brilliant physicist and is very handsome. Cat calls him sexy despite not being fond of him.
* IconicOutfit: While Lord wears a variety of clothes, they tend to be typical formal men's wear, but with one notable, RuleOfSymbolism exception-he never wears a necktie as a sort of way of keeping him more youthful and progressive seeming.
* InsufferableGenius: 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.
* JerkassHasAPoint: 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.
* JerkWithAHeartOfGold: 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.
* LonelyAtTheTop: Due to his distrust in people.
* MeaningfulName: He wishes to lord over humanity and he definitely has a God complex.
* NotMeThisTime: 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 [[KryptoniteFactor regular green kryptonite]].
* PermaStubble: He has a short beard. J'onn mocks it once while impersonating him.
* SecondEpisodeIntroduction: Introduced in the second episode of the entire series.
* SecretKeeper: She has not outed Kara as Supergirl after discovering her identity.
* SharpDressedMan: He's not seen without a suit.
* ShipTease: 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.
* TookALevelInJerkass: 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 GodzillaThreshold. He also helps out against Non and company as things get hot.
* UngratefulBastard: Kara rescues him from Reactron, but he intentionally robs her of the credit.
* VillainousCrush: 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.
* VillainWithGoodPublicity:
** He orchestrated the bombing campaign against his own company in "[[Recap/Supergirl2015S1E4HowDoesSheDoIt 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.
* WhatHappenedToTheMouse: Disappears without explanations and has had only two mentions, despite [[SequelHook 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 SuspiciouslySimilarSubstitute.

A rich businessman with a personal disdain for Lena Luthor, who doesn't shy extreme measures to damage her reputation.
----
* ArchEnemy: For Lena, ever since she bought [=CatCo=] before him. He will do ''anything'' to ruin her reputation.
* BigBadEnsemble: With Reign in Season 3.
* BigBadWannabe: Isn't half as powerful or threatening as he thinks he is....at least in his first appearance. After that, he shows Lena and Kara that he is ''not'' playing around.
* CorruptCorporateExecutive: Plans to take over [=CatCo=] to build up a PropagandaMachine against Lena and has no problems with hiring terrorists.
* DidntThinkThisThrough: His plan to hire a terrorist to attack the bay; he immediately drew attention to himself because he was quite vocal about his desire to redevelop it and therefore was the most obvious suspect. Also he didn't really take into account how somebody like Lillian Luthor would react to his constant attempts to kill her daughter ...
* EvilIsPetty: He's very petty towards Lena, as well as James, for making their distaste for him and his ideas for National City known. He tries to buy [=CatCo=] out from under James in retaliation, and threatens to make trouble for Lena when she beats him to the punch. He makes good on that by trying to interfere with her business in "The Faithful", filing an anti-trust lawsuit that gets instantly slapped down, apparently for no other reason than to be obnoxious.
** That's nothing compared to when when he poisons a public pool with a chemical that produces lead poisoning symptoms all so he can blame it on Lena's bomb to get rid of the Daxmaites and destroy her reputation.
* FauxAffablyEvil: Is able to put up an act of friendliness whenever he needs to, especially in front of cameras.
* HateSink: Each episode he's in makes it abundantly what a spiteful, nasty, piece of work he is. He will kill dozens or poison hundreds of children just to get petty revenge on a business rival.
* {{Hypocrite}}: Attacks Lena and James for everything he does.
* {{Foil}}: To Maxwell Lord. Lord, honestly wants to make the world a better place, despite his Bad Boss tendencies. Edge is motivated only by his greed and pettiness.
* {{Jerkass}}: When he isn't putting up an act, he quite easily qualifies as ''the'' most unpleasent human in the series period.
* KarmaHoudini: Has yet to pay for any of his numerous crimes, despite being incredibly sloppy in his execution of them. He even evades [[spoiler: Reign]] in a [[CrazyPrepared lead-clad saferoom.]]
* KarmaHoudiniWarranty: [[spoiler: His luck finally runs out in "For Good" where Lena manages to get a confession of his crimes out of him.]]
* NoCelebritiesWereHarmed: This version of Edge is a very clear reference to Donald Trump, being a wealthy real estate mogul with a dim view of the news media. (Which is funny, considering the comic book version of Edge was a media mogul).
* NotMeThisTime: Lena immediately suspects him to be behind the Kryptonian graffiti, but he isn't. He does send an assassin after her, however.
* PoliticallyIncorrectVillain: Makes some pretty sexist remarks towards Lena.
* StrawmanPolitical: "For Good" firmly establishes him as also hating Lena and James for being the "liberal media."
* SuspiciouslySimilarSubstitute: For Lex Luthor (who's currently in jail) and Maxwell Lord who hasn't been seen since Season One -- a businessman who's a thorn in the hero's side because he's always able to get away with his crimes; rather than being a media mogul like in the comics, he's a businessman with a variety of interests like Lex. However, [[{{Foil}} he turns out to be quite different from Lord]]. Lord did a lot of dark stuff because he really, truly believed it necessary to protect the world, and always stopped short of ''truly'' becoming the new Lex, and in the end helped the heroes, putting him in AntiVillain territory. Edge is played enough like Lord that you'll think they're the same for about one episode... then you find out how capital-E Evil this guy is.
* SmugSnake: Which makes him being left on a container ship at least a few miles away from National City by Supergirl all the more satisfying.
* TheUnfettered: He is fine with hiring a terrorist and endangering hundreds if not thousands of innocents lives to reach his goals.... and poison children to destroy one woman's life.
* VillainHasAPoint:
** He is not entirely wrong about the fact that a lot of the good Lena is at least partially motivated by her guilt for the actions of her brother, mother, and even her own actions for helping bring on the Daxamite invasion.
** He also not wrong about [=CatCo=] becoming increasingly more biased since James took over, as it has been shown that he doesn't want articles saying bad things about superheroes or aliens. Then again, [[{{Hypocrite}} he plans to turn it into his personal propaganda machine]].
* VillainWithGoodPublicity: Acts like a philanthropist towards the public. [[spoiler:Might finally be at an end after Lena gets him to confess his crimes.]]
* WouldHarmAChild: He poisoned a public pool with a chemical that produces lead poisoning symptoms, that made dozens of children seriously ill all to destroy Lena's repuation.

Samantha's daughter, with whom she was [[TeenPregnancy pregnant already as a teenager]]. She is a huge fan of Supergirl.
----
* AdultFear: Is repeatedly put into dangerous situations, much to the horror of her mother.
* AmbiguouslyHuman: Lena's research shows that the Worldkillers' DNA rewrites itself when their Worldkiller selves are dominant and is human when their human personas are in control. Thus, there's no reason to think Ruby, who is Sam's daughter, not Reign's, is anything but human. However, Sam is still born in Krypton from Kryptonian parents.

----
* ActionGirl: Moreso than the comic Maggie.
* AdaptationDyeJob: Blond in the comics. Here, she's played by a brunet actress.
* AdvertisedExtra: Her actress' name is included in the OBB, but she's mainly a SatelliteLoveInterest to Alex.
* AloofDarkHairedGirl: When on the job, she's stoically commited 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.
* AmazonChaser: Just [[http://smolsawyer.tumblr.com/post/160213572740/mark-me-and-maggie-sawyer-as-scared-and-horny look]] at her reaction to Alex punching Richard Malverne, the man who kidnapped and threatened her life in "Alex".

* ClosetKey: 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.

* FairCop: Maggie is a very attractive police officer and gets her fair share of attention from females of many species, Alex included.

* TwoFirstNames: "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 InformedFlaw, however, since ''Alex'' seems to be the workaholic of the two.)

----

* ActionGirl: She takes out ''two'' alien thugs at once in the alien bar, single-handedly. Even though it's later discovered the thugs were hired to harass Winn, she still has combat ability. Later, she joins Guardian and Winn's crime-fighting team, though she's a little over-enthusiastic at first.

* BitchInSheepsClothing: All her affections for Winn are just for show in order for her to accomplish a con. Or, at least, that's how she makes it appear.

* CantTakeCriticism: Lyra gets angry when James tries to kick her out from his team.
* ConMan: She romanced Winn to gain access to a museum for a LongGame art heist.
* CrapsackWorld: Starhaven, according to Winn, "smells like cinnamon". Lyra corrects him, saying a blight struck the planet and is no longer a paradise world.

* GoodIsNotNice: She can be outright aggresive in her vigilante work.

----
* AdaptationNameChange: In the comics, Cat's son is named Adam Morgan. It is then revealed that they're a DecompositeCharacter.
* AmbiguousDisorder: 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.
* DecompositeCharacter: With his half-brother Adam Foster, for Cat’s son in the comics, Adam Morgan. He gets the age while Adam gets the name.

!!! '''Appearances:''' ''Series/{{Supergirl|2015}}''

A confrontational radio ShockJock that gets powers after being zapped by lightning while being saved by Kara.
----
* AdaptationalAttractiveness: Livewire usually has a more Ghoulish appearance in the canon comic line. Here, she retains her feminine appearance after her transformation which is a lot like her cartoon look, though less blue.
* AdaptationalModesty: After becoming Livewire, she doesn't wear her AbsoluteCleavage showing LeotardOfPower of a costume. Instead, she goes full on CivvieSpandex.
* AdaptationDyeJob: Before and after becoming Livewire. As Leslie, her hair was black when she was first introduced in ''WesternAnimation/SupermanTheAnimatedSeries'' and as Livewire it's (fittingly) electric blue, while here Leslie is blond and Livewire has bluish white hair.
* ArchEnemy: Kara considers her to be her nemesis. Certainly she's Kara's most recurring non-ArcVillain enemy.
* BerserkButton: After the incident that gave Leslie her powers, she really hates helicopters.
* BreakoutVillain: The most popular of Kara's nemesis. Said popularity is the reason why she was made Kara's most recurring foe.
* CivvieSpandex: She's still wearing her casual clothes even as a supervillain.
* ContraltoOfDanger: Her voice as Livewire sounds more deep and distorted, especially if she's not "physically manifesting".
* CreateYourOwnVillain: She gave a TakeThat to Supergirl on live radio which results to Cat demoting her to traffic report duties. During one of those duties, she was zapped by lightning along with Supergirl while the latter is rescuing her from the chopper she was riding. Said incident gave her powers. After realizing she now has powers, she vowed revenge on both Cat and Supergirl, making their lives hell if she gets the chance.
* DramaticIrony: Spent most of her time trying to kill Cat Grant and Supergirl, then she dies saving Supergirl.
* EnergyBeings: She can exist as pure energy, though she has to take physical form to do more than mess with electronics.
* EstablishingCharacterMoment: As Leslie Willis, we are shown her radio show as the entire cast reacts in varying levels of anger as she callously rips on Supergirl.
* EnemyMine: Teams up with Supergirl and Psi to fight against Reign.
* EvenEvilHasStandards: She intends on killing Cat Grant again in "World's Finest", but when Cat pleads for her life because she doesn't want her sons to be left alone without a mother, Livewire is visibly affected and starts to reconsider, unlike Siobhan.
* EvilFeelsGood: She clearly gets a rush from using her powers to get revenge on Cat.
* EvilIsHammy: Brit Morgan is clearly having a blast with the role.
* {{Foil}}: To Kara Danvers. Both of them are protegees of Cat Grant, who tries to "push" them to greatness. Leslie has become cruel and vindictive in her attempt to "push" back, while Kara remains patient and friendly.
* FreudianExcuse: As a shock jock, Leslie has always been rewarded for being mean and nasty, leading Cat to feel she is to blame for Livewire's actions as the one who has been rewarding her for years.
* HeroicSacrifice: She does this to save Supergirl and is fatally injured by Reign's eyebeams. Supergirl even mourns her after her death.
* InstantExpert: She gains control of her powers remarkably quickly.
* {{Jerkass}}: She starts the episode by going on a long rant about all the reasons she thinks Supergirl is awful and from her conversation with Cat, this seems to be her standard M.O.
* JustForPun: A ShockJock getting ShockAndAwe powers.
* KryptoniteFactor: Water really doesn't play well with Livewire.
* LightningCanDoAnything: From manipulating electronics to forming whips. This is given a justification in that she got zapped by lightning that was filtered through Kryptonian biology.
* LockedIntoStrangeness: Getting struck by lightning through Supergirl gave her white hair and electricity powers.
* MuggingTheMonster: Immediately after discovering her ability to move through wires, she finds herself in an alleyway. A lowlife attempts this trope on her, even commenting on the stupidity of someone as good looking as she was coming to that part of town. It doesn't end well for him.
* MysticalWhiteHair: She has white/very light blue-ish hair and is a PsychoElectro.
* MythologyGag:
** Leslie's rebirth as Livewire is the same as in her first appearance, being struck by lightning through a Kryptonian just like in the similarly named [[Recap/SupermanTheAnimatedSeriesS2E5Livewire debut episode]] for her character in ''Superman: The Animated Series''. She was also introduced in that episode insulting Superman on her show.
** Her defeat in ''[[Recap/Supergirl2015S1E5Livewire Livewire]]'' is also identical to her defeat in the same episode.
** She also gives a remarkably similar speech about her rebirth.
--->'''Livewire:''' Leslie Willis is dead. Meet Leslie 2.0. ''
* NiceJobFixingItVillain: After Kara spends two episodes struggling to restore her reputation after her Red Kryptonite-induced rampage, Livewire impulsively tries to shoot down a police helicopter. Kara takes the hit herself in front of a huge crowd, who start seeing her as a hero again.
* NotMeThisTime: Lucy blames the early stages of Myriad on her. She really has nothing to do with it, as she was obviously imprisoned at the time.
* PsychoElectro: She's got a few screws loose after she gets her powers.
* APupilOfMineUntilSheTurnedToEvil: She is Cat Grant's first protegee gone bad, the second being Siobhan Smythe aka Silver Banshee. Cat later lampshades this.
* RedemptionRejection: During their first fight, Kara offers to help her. She says she's "good as is."
* RedemptionEqualsDeath: She jumps in front of Supergirl to save her from Reigns eye beams, she dies moments after Reign flees from the battle after Psi uses her abilities on her.
* RideTheLightning: Is able to travel by wire, or even hijack television screens to plaster her face over it.
* RoguesGalleryTransplant: Livewire is usually a Superman villain, at least until her HeelFaceTurn in the comics, who originated in ''WesternAnimation/SupermanTheAnimatedSeries'', before popularity made her [[CanonImmigrant a canon comic character]]. Her creation in this show is almost exactly like it was in the cartoon, except the lightning passed through Kara instead of Superman.
* ShockAndAwe: She's got electricity powers.
* ShockJock: Of course, crossing Cat Grant by going after Supergirl had gotten her transferred to traffic helicopter.
* SlasherSmile: She can't help herself but enjoy being a PsychoElectro.
* SpoiledBrat: Cat Grant sees her like a daughter who wasn't put limits.
* StatuesqueStunner: She stands 5'8 1/2 and one guy even comments on how hot she is.
* TakingTheBullet: She jumps in front of Reign's eye beams to save Supergirl.
* TallDarkAndSnarky: On paper, she's a sure-in StatuesqueStunner given her height (she's 5'8 1/2, a little taller than Kara herself) and beauty. However, her {{Jerkass}} behavior pretty much overwhelm every attractive traits she has.
* ThatManIsDead: Livewire claims that Leslie Willis died on the helicopter and thinks of herself as "Leslie 2.0".
* TranshumanTreachery: Describes her transformation as "ascendance" while attacking Cat Grant.
* TrueBlueFemininity: All her outfits has blue in it in one form or another. However, she does not have both the fairness and gentleness usually associated with the trope.
* VillainTeamUp: With Silver Banshee.
* WeaksauceWeakness: Can be incapacitated by little more than a garden hose.
* WhiteHairBlackHeart: She's a PsychoElectro with a MysticalWhiteHair.
* WithGreatPowerComesGreatInsanity: Step 1) Realize you have superpowers. Step 2) Try to murder your boss. Apparently, EvilFeelsGood. ''Really'' good.
* YouGottaHaveBlueHair: She has very light blue-ish hair as Livewire.

A clone of Supergirl created by Maxwell Lord to discredit her.
----
* BlackEyesOfEvil: Once she's corrupted by green kryptonite, her eyes turn completely black.
* CloneByConversion: She was made through a combination of gene splicing and plastic surgery.
* CompositeCharacter: Slightly. The original Superman-based Bizarro apparently doesn't exist here, leaving her to simply have that name instead of the comics' Bizarro-Girl.
* EvilKnockoff: Lord created her to ruin Supergirl's reputation and ultimately kill her. She has Supergirl's basic powers, but her EyeBeams freeze and she breathes fire.
* FacialHorror: Getting shot with kryptonite causes her skin to turn grey, and her face starts cracking off, which is a reference to the original Bizarro's look.
* HulkSpeak: On account of being comatose and brain-dead when Max picked her up. Getting her to understand language was impressive in itself.
* NatureVersusNurture: Despite Lord's best attempts to condition her into a killing machine, she is not an evil person at heart and only ever attempts to kill Supergirl. She even stops fighting Supergirl in their first encounter because Supergirl is trying to rescue some civilians. James tries to appeal to this side of her when she kidnaps him.
* PsychopathicManchild: As always the case with any Bizarro.
* TragicMonster: Kara is quick to point out that she's a pure victim of the situation, as a severely brain-damaged woman who's been manipulated into being a soldier in Maxwell Lord's war. After she's defeated, the DEO returns her to her comatose state hoping they can find a way to reverse what was done to her.

A new hire at [=CatCo=] Worldwide Media who clashes with Kara and later Supergirl.
----
* AdaptationDyeJob: In her 'civilian' guise comicbook Siobhan has white hair and blue eyes while TV Siobhan has brown hair and brown eyes. JustifiedTrope as this version could be one of the so-called "[[http://www.irishcentral.com/roots/history/who-were-the-black-irish-92376439-237784721.html black Irish]]."
* AdaptationPersonalityChange: In the ComicBook/{{New52}} version of ''ComicBook/{{Supergirl}}'', Siobhan Smythe is one of Kara's first friends after she arrives on Earth. Here, she hates Kara and eventually becomes Silver Banshee.
* AdaptationalNationality: The ComicBook/{{New52}} version of the character is an Irish girl who emigrated to America in her late teens. Here she is American of Irish descent.
* AdaptationalVillainy: As part of her CompositeCharacter nature. She shares her name with the ComicBook/{{New52}} Siobhan who is a NiceGirl and Kara's friend. In every other aspect she more closely resembles the villainous Siobhan [=MacDougal=] of the older comics.
* AlliterativeName: '''S'''iobhan '''S'''mythe.
* AloofDarkHairedGirl: She doesn't give a shit about other people unless they can benefit her.
* AmbitionIsEvil: She dreams of becoming a powerful figure.
* CelebrityParadox: Cat mentions ''Series/TheXFiles'' early in Season One despite the fact that her actress' RealLife [[Creator/RobbieAmell husband]] is part of that show's SequelSeries[[note]]Said husband also plays [[ComicBook/{{Firestorm}} Ronnie Raymond]] in the main Series/{{Arrowverse}} in two different {{Alternate Universe}}s, though whether or not he has an AlternateSelf here remains to be seen[[/note]].
* CompositeCharacter: She's named Siobhan Smythe, who was Kara's friend in the ComicBook/{{New52}} comics. However, she is Kara's enemy here, making her more similar to Siobhan [=MacDougal=], the Silver Banshee of the original comics.
* CursedWithAwesome: Her Silver Banshee powers come from an Irish ancestor pissing off a real banshee; now the women of her family are cursed to be unpleasant, and when they feel they have been wronged, the Banshee power develops until the one who wronged them is dead.
* CynicismCatalyst: When she was 17, Siobhan caught her dad cheating with his personal assistant. This convinced her that everyone is selfish and any kindness is a cheap façade.
* DeceptiveDisciple: She seemed a reliable assistant, but she is willing to sell a story to Perry White, a rival to [=CatCo=]. She gets fired and Perry White assures Cat that he would not hire Siobhan.
* EvilCannotComprehendGood: As Siobhan is so selfish and her opinion of humanity so low, she finds the concept of people acting with altruism and honour laughable, no matter how many times they prove her otherwise.
* EvilMakeover: Gets one from Livewire after they team up.
* FreudianExcuse: She caught her father having sex with his assistant.
* FightingIrish: She has Irish heritage and her power comes from an old Irish curse.
* FromNobodyToNightmare: Cat had no idea whom she had hired to be her assistant.
* GoGetterGirl: She is a very driven person.
* HumiliationConga: Circumstances surrounding her firing, and her actions in an attempt to win her job back, blew up on her face '''big time'''.
* {{Hypocrite}}: She labels Kara as a "mean girl," despite the fact that she had been treating Kara like dirt since the day they met.
* ImNotHereToMakeFriends: Said word-per-word towards Kara, and it shows.
* InferioritySuperiorityComplex: She loves acting smug, but she's easily demoralized when faced with failure.
* InNameOnly: Literally the case with her ComicBook/{{New52}} couterpart given she has different nationality, personality, morality, job, family history and even hair colour from the comic Siobhan. She has a bit more in common with Siobhan [=MacDougal=] (being evil for instance) but is still quite radically altered.
* ItIsPronouncedTroPay: Kara had a hard time pronouncing her first name (it's an Irish form of Jane, and pronounced "Sheh-von").
* ItsAllAboutMe: She exhibits this in a conversation with Kara about how she intends to become the next Cat Grant, and dismissively says that Kara will be her underling.
* {{Jerkass}}: She firmly establishes herself as this when, after Cat fires her, she tries to get back at Kara by impersonating her in a nasty email.
* MakeMeWannaShout: She finally reveals her powers at the end of "Manhunter", using her screams to break what would have otherwise been a rather nasty fall.
* MoralMyopia: She considers Kara exposing her attempt to send her "evil Supergirl" story to the Daily Planet to be the act of a "mean girl," but shortly after tries to forge an insulting e-mail to Cat so Kara will be fired.
* NeverMyFault: She refuses to take any responsibility for the duplicitous actions that got her fired and nearly arrested, instead blaming everything on Kara and wanting revenge.
* OutsideGenreFoe: Mildly. She's the first villain in the show whose powers have a magical rather than a scientific explanation. However, Supergirl and the Flash have no problem defeating her like any other metahuman criminal.
* PersonaNonGrata: After intending to sell a scoop to a rival company and impersonate Kara Danvers, Siobhan Smythe is no longer well received in [=CatCo=].
* PrimalScene: She tells Winn that she caught her father ''literally'' in the act with his personal assistant.
* ProfessionalButtKisser: She knows how to suck up to the higher-ups at [=CatCo=].
* RedemptionRejection: As Silver Banshee, she shuts down any attempt to help her.
* RewardedAsATraitorDeserves: A non-fatal example. After Cat discovers that she's planning to betray her, she got herself immediately fired.
* TheRival: For Kara in [=CatCo=].
* RivalTurnedEvil: She is slated to become the supervillain Silver Banshee, which was announced weeks before she even appears.
* RoleEndingMisdemeanor: In-universe, intending to sell information to a rival company and trying to defame someone else ruined her work at [=CatCo=] and made many employers wary of hiring her.
* RomanticFalseLead: For Winn. The two have a brief relationship, which is promptly followed by her becoming a villain.
* SassySecretary: She gets the secretary job done much better than Kara, and she won't hesitate to rub it in her nose. However, this only lasts until the job moves beyond butt-kissing, at which point her weaknesses start to show.
* SecondLove: She's the first girl that interests Winn after he lets go of Kara. Unfortunately for him, she goes to the dark side.
* SexySecretary: She's easy on the eyes.
* SkilledButNaive: She's a good PA and a great ProfessionalButtKisser, but she can't match Kara's years of experience at learning Cat's every quirk and pet peeve.
* SmallNameBigEgo: Despite [[AlphaBitch acting and talking big]], she doesn't really live up to her boasts.
* SmugSnake: She always displays an aura of overconfidence when around Kara, despite not being nearly as cunning as she thinks she is; her WrongGenreSavvy acts quickly come back to bite her in the ass.
* SuperStrength: She's able to send Kara flying with a punch.
* TraumaticSuperpowerAwakening: Her power awakens and saves her at the last minute from what would have otherwise been a rather nasty fall.
* VillainTeamUp: With Livewire.
* WrongGenreSavvy: The cause of her downfall as she assumes being an AlphaBitch and ProfessionalButtKisser will make her "bigger than Cat Grant" in no time, not grasping she doesn't have the smarts, talent or dedication to be anywhere near Cat's level.
** When Cat is uncertain about publishing a story of Supergirl gone rogue, Siobhan tries to sell it to the Daily Planet, thinking they'll love a scoop on a rival. She doesn't expect Perry White to have the integrity to call Cat and tell her about the deal.
** Cat openly lampshades how Siobhan thinks she's the "plucky go-getting reporter" who will make a big splash with the story and Cat will be so impressed by her gumption that she'll hire Siobhan on as a full writer. Instead Cat calls Siobhan a "backstabbing imp" and fires her.

!!! '''Species:''' Enhanced human
!!! '''Portrayed By''': Creator/WilliamMapother
!!! '''Appearances:''' ''Series/{{Supergirl|2015}}''

A climate change expert who is infected with an alien parasite.
----
* AdaptationDeviation: In the comics, Rudy was a STAR Labs janitor who became a mutant when exposed to radioactive waste. The ''Supergirl'' version is infected with a literal symbiotic parasite akin to the facehuggers from ''Franchise/{{Alien}}''.
* AdaptationalHeroism: He has good intentions when stopping climate change deniers, since for him they are harming the planet.
* CelebrityParadox: ''Series/{{Lost}}'' was mentioned during the ''Series/{{Arrow}}'' series premiere, even though his actor plays a major antagonist there. However, ''Arrow'' is on an AlternateUniverse, so the paradox might be a subversion.
* ComicBookMoviesDontUseCodenames: He's only referred to as Parasite once, by himself, when fully transformed and trying to kill Mon-El.
* MoreTeethThanTheOsmondFamily: For each of his NestedMouths, no less.
* NestedMouths: His Parasite form has ''several'' of them.
* PowerParasite: He has the ability to drain energy from his victims.
* PurpleIsPowerful: As with most versions of Parasite, he has a purple color scheme.
* RoguesGalleryTransplant: Parasite is usually a Superman villain. He also fought the Linda Danvers version of Supergirl, but never the Kara Zor-El version of Supergirl.
* ShoutOut: Both to ''Franchise/{{Alien}}'' and ''Film/{{The Thing|1982}}'' -- an extra-terrestrial found frozen in an icy environment in the guise of a dog that kills most of the scientists working there, and when its true monstrous form is revealed, it opens its maw hiding even tinier mouths.
* WasOnceAMan: Once an ordinary human, until he became infected with an alien parasite.
* WellIntentionedExtremist: Most versions of Rudy were apathetic citizens or petty criminals at worst. Rudy here is a fanatical climate change scientist who believes he is saving the world, and eliminates anyone who might impede his scientific work.

A bank robber who has the ability to instill fear in others. Born in Skokie, Illinois, the same as her comic counterpart.
----
* AdaptationDyeJob: All comic versions of Gayle have black hair. Here she has light blonde hair.
* AdaptationalVillainy: In the comics, Gayle uses to play the role of misunderstood antagonist or naive girl who has been deceived into doing bad things. In the show she's an outright criminal.
* BigDamnHeroes: Saves Supergirl from Reign by causing her fears to manifest, which causes her to flee.
* EnemyMine: Is recruited alongside Livewire by Kara and Imra to assist them during their mission to Fort Rozz.
* MindOverMatter: She even uses the phrase on Kara. Becomes an IronicEcho when Kara overcomes her powers and then knocks her out.
* PetTheDog: Actually saves Kara instead of just running away and [[spoiler:offers her condolences after Leslie's death]].
* PersonOfMassDestruction: During the climax, she assaults an entire street, including a construction worker operating a wrecking ball, which wreaks some serious havok.
* PsychopathicWomanchild: Her behaviour is very off, citing child stories and acting like a little girl playing with her toys.
* SupernaturalFearInducer: Her powers. Her fear waves are sometimes so strong that they can physically knock back a person, even a superpowered one like Kara.
* SuspiciouslySimilarSubstitute: After [[spoiler:Livewire's death]], Psi seems to be taking up the mantle of Kara's slightly mentally ill nemesis with the potential for future redemption. Their physical resemblance additionally contributes to that.

----
* AbusiveParents: When Winn was a child he drove Winn and his wife off the road when they tried to get away from him, and he threatened to kill Winn if she ever tried to take Winn away again. By the time of the series, he tried to force Winn to kill Chester Dunholtz to ride him into villainy.
* ActionDad: He is Winn's estranged father and a scary man.
* AdaptationDyeJob: He's an EvilRedhead in the comics. Here, he has gray hair and his actor has brown hair in his youth.

* BadassNormal: He has no powers, but he's a genius inventor who's able to pose a threat to Kara.
* CelebrityParadox: ''Series/{{Quantico}}'' is mentioned on Season Two. His actor plays a RecurringCharacter there.
* CrazyPrepared: The main reason he's able to be a threat to Supergirl despite being a normal human.
* DomesticAbuser: It turns out he was abusive to his wife and forced her to stay away from Winn.

* FourEyesZeroSoul: He wears glasses with very thick lenses.

* IHaveNoSon: Inverted. Winn was the one who (rightfully) disowned him.
* ImprovisedWeapon: All of his weapons are modeled like toys.
* KillerYoYo: Uses one when he escaped.
* NotHisSled: As noted with Winn, it's the inverse of the "Winslow Schott Sr./Jr." situation on ''WesternAimation/SupermanTheAnimatedSeries'': It's Senior who's Toyman, not Junior.
* RoguesGalleryTransplant: He's a Superman villain in the comics, but here he is a Supergirl villain.
* SanitySlippage: He snapped after his company was stolen from him, and being imprisoned for almost two decades just made him worse. [[spoiler:Except he was always evil, since he was always a domineering man]].
* TheyLookJustLikeEveryoneElse: Winn said his dad was a very happy toymaker. But it turns out Winslow was always secretly angry deep down, but never said anything because he was afraid. It was having his projects being stolen by his boss that finally pushed him over the edge.

An old classmate of Lena Luthor who runs illegal fight clubs that cater to the rich and powerful. Her latest fight club is an alien one with willing and not so willing participants.
----

* AloofDarkHairedGirl: She has a very apathetic demeanor.
* CelebrityParadox: Winn explicitly mentions ''Series/DoctorWho'' during the battle with Indigo. Her actress guest-starred on the SpinOff ''Series/TorchwoodMiracleDay''.
* DragonLady: Complete with dragon tattoos all around her body.
* FantasticRacism: Roulette's schemes are often at the cost of aliens. As aliens have no rights, she is willing to exploit them to make a quick buck.
* FightClubbing: She's the main promoter of a string of illegal fight clubs. The latest one uses aliens for fighters. [[ForcedPrizeFight Not all of them willingly]].
* {{Foil}}: She and Lillian Luthor. Both have FantasticRacism, abuse aliens in shadowy organizations and utilize ScrewTheRulesIHaveConnections. However, Veronica is a society GrandDame with no reason to hide while Lillian is an EvilMatriarch who prefers to work behind closed doors.
* ForTheEvulz: She hosts her fight clubs not for the money, but because she enjoys the blood sport.
* FurAndLoathing: Will occasionally wear a black fur coat when she goes out.
* KarmaHoudini:
** She's able to weasel out of trouble in her debut appearance due to having the right friends in the right places. However Alex and Maggie make it clear that they're both keeping a close eye on her activities.
** In her second appearance she's apparently left stranded on an alien planet where some buyers had been expecting to get human slaves, though nothing's made clear.
* LadyInRed: Always wears a red {{Qipao}}.
* LargeHam: But only in the ring. Outside she's more soft-spoken and chilling.
* LimitedWardrobe: Wears the same red Qiapo and black fur coat every night.
* LoopholeAbuse: At the time of the episode, aliens weren't protected by the law, which is why Sinclair escaped custody so quickly.
* NervesOfSteel: You wouldn't run an alien fight club if you were afraid of them. Not even Supergirl ''Heat Visioning her'' can make her blink. She doesn't even spill her champagne.
* OffOnATechnicality: It's hard to keep her incarcerated.
* RaceLift: In the comics she's a white girl who ''wants'' to be a DragonLady and so dresses the part. Here she's of Asian descent, like she was in ''Series/{{Smallville}}''.
* RichBitch: Her BackStory, according to Lena. If so, she hasn't changed one iota as an adult.

* ArmCannon: Uses a wrist-mounted machine gun similar to the ones used by ComicBook/{{Deadshot}}.
* ComicBookMoviesDontUseCodenames: The show doesn't designate Phillip by his "Barrage" name from the comics.

* {{Expy}}: Basically the show's version of ComicBook/ThePunisher.
* JudgeJuryAndExecutioner: Chiefly because he thinks the legal system has failed.

!!! '''Appearances:''' ''Series/{{Supergirl|2015}}''

A former lawyer who turned to alcoholism before he found a new purpose in his life after being rescued by Supergirl.
----
* AffablyEvil: He's easily one of Supergirl's nicest human enemies. When Kara visits him in prison, he claims he already forgot the name of her civilian identity, but he calls her business number when he wants to warn her about Reign, meaning he lied to ease her mind.
* TheBusCameBack: Warns Kara about Reign in the mid-season finale of Season 3. [[spoiler: And later joins Reign.]]
* {{Cult}}: The leader of one who hails Supergirl as a Messiah and a God.
* TheCynic: Before being saved by Supergirl, he was at a low-point due to being recently divorced after discovering that his wife was cheating on him with her personal trainer.
* DesperatelyLookingForAPurposeInLife: The reason why he founded the Cult. Whether by outside influences or his own design, he has nothing left in his life outside of worshiping Supergirl.
* TheDragon: [[spoiler: To Reign, after his FaceHeelTurn. And later briefly to Selena, before she disposes of him.]]
* FromNobodyToNightmare: From an alcoholic ex-lawyer to a dangerous Cult leader.
* TheFundamentalist: Takes his beliefs to dangerous extremes, encouraging people to purposely endanger their lives to experience being saved by Supergirl, and even planning to blow up a stadium in order to make her save hundreds at once. [[spoiler: He later turns on Supergirl and allies himself with Reign, believing Reign's rule over Earth is preordained.]]
* MyGodWhatHaveIDone: After seeing Kara bleed under the effects of kryptonite, he realizes how he screwed up and helps Kara and Alex dispose of the bomb. His faith isn't entirely shattered, however; now he sees it as his mission to guide Kara toward her destiny, even offering her information on Reign that Kara herself couln't find with Krypton's vast library at her disposal.
* NotQuiteDead: [[spoiler: In the finale, he is shown to have survived being blasted by Heat Vision, drags himself into the Kryptonian Ship and sends a distress call. Its not shown whether he ultimately survives his injuries or not.]]
* ObliviouslyEvil: He's a nice and compassionate man who genuinely does not understand why encouraging his flock to endanger themselves and others for their belief is wrong.
* TheQuisling: [[spoiler: Following Supergirl's initial defeat by Reign's hands, he's all too happy to align himself with the Kryptonian Worldkiller cult to aid with them terraforming Earth.]]
* SecretKeeper: He knows Kara is Supergirl at a glance, but promises to respect her desire for privacy.
* WellIntentionedExtremist: He is not actually Kara's enemy. However, ever since Kara saved his life, he started to ''worship'' her as a god and offers her his help because he sees that she is in conflict with her civilian life and her life as a superhero. In his attempt to make more people believe in Supergirl, he endangers a lot of other innocent people and the members of his cult, though, and Kara almost dies when he intends to detonate a bomb laced with kryptonite.
* YouHaveOutlivedYourUsefulness: [[spoiler: On the receiving end by Selena. After fulfilling his part in resurrecting Reign, she seemingly kills him with her Heat Vision.]]
[[/folder]]

* {{Brownface}}: Maggie is stated in the show as being of Mexican descent but is played by a tanned non-Latina Italian actress.

* SpottingTheThread: Cat is very observant, spotting even the smallest details about something or someone. She even easily figures out that Kara is Supergirl and that James is Guardian.

* JumpingOffTheSlipperySlope: [[spoiler: In "Battles Lost and Won" she lied to Supergirl about giving Alura all of the Harun-El. She secretly kept some of it to experiment it.]]

* HappilyAdopted: Slightly averted, she did love and was loved by Lionel and Lex growing up, but [[WellDoneDaughterGal craved approval and affection]] from Lillian. In the end completely averted, when Lillian reveales she is indeed a biological Luthor all along.

* HotScientist: Along with being exceptionally beautiful, she is a verified tech genius, and once was involved in researching nanotechnology

* GoodIsNotSoft: She may be on the heroes' side, but still doesn't hesitate to gun down the man who tried to kill her, which would have killed him if Cadmus hadn't gotten to him; in Season 3 she engages in a brief debate over gun ownership and states flatly that she has used a gun in self-defence. In a later episode she doesn't hesitate to help Supergirl by attempting hand to hand combat with someone who makes a BadassBoast of being a black belt (and holding her own).

* ItsAllMyFault: After many children of National City [[spoiler: begin to show signs similar to lead poisoning]], she doesn't deny or reflect blame that [[spoiler: her lead bomb used to repel the Daxamites]] could be the catalyst. Devestated she offers a sincere and gripping apology to the public and almost steps down from L Corp and [=CatCo=]

* NotSoDifferent: Like Lex, she has a really good knack at developing anti-Krypton technology; albeit she uses it to keep Reign at bay, but Supergirl is still disturbed by the implications. After her Supergirl becomes a BrokenPedestal due to a breach of trust, Lena makes some very Lex-like comments about Supergirl's "superiority" to Kara.

** Of L Corps. Is very kind to her employees and takes a hands on approach in ensuring their productivity and moral remains high.

* WhatHappenedToTheMouse: After Reign tries to kill him, he disappears and isn't referred to for the rest of Season Three.

!!! '''Species:''' Human

** Subverted. Lena's research shows that the Worldkillers' DNA rewrites itself when their Worldkiller selves are dominant and is human when their human personas are in control. Thus, there's no reason to think Ruby, who is Sam's daughter, not Reign's, is anything but human.

* WhatHappenedToTheMouse: When last seen she and Winn were still going strong, even on the verge of forming a Power Trio with him and James in their work as vigilantes, but she up and vanishes near the end of season 2.

* TheDragon: [[spoiler: To Reign, after his FaceHeelTurn.]]

* ChuckCunninghamSyndrome: He disappears from the series without any explanation after Season 1.

* HiddenDepths: To be inferred, since Cat Grant has an amazing eye for talent. If she didn't, she'd have been fired already. Turns out a she's scientist you graduated from Yale.

* GoodIsNotSoft: She may be on the heroes' side, but still doesn't hesitate to gun down the man who tried to kill her, which would have killed him if Cadmus hadn't gotten to him. In a later episode she doesn't hesitate to help Supergirl by attempting hand to hand combat with someone who makes a BadassBoast of being a black belt (and holding her own).

* IAmNotMyFather: If there were any questions about Lena's morals, they were answered when she foiled her mother's plan to kill all aliens with a virus.

** She is also friendly with Winn, who to her is just a random tech geek, though they are nowhere near as close as she is with Kara.
* OnlyFriend: Increasingly views Kara as this. Later begins to see Samantha this way too.

* WeUsedToBeFriends: She no longer considers Supergirl her friend after she asked James to break into her lab to see if she had anymore Kryptonite. Supergirl ''wants'' to be still friend, but Lena point-blank refuses.
