Portrayed By: Laura Benanti (Seasons 1 and 2), Erica Durance (Season 3 onwards)

see Smallville: Lanes for Lois Lane, the Earth-167 character who bears her physical likeness

see Smallville: Earth-2 for Lois Lane, the Alternate Universe Earth-167 character who bears her physical likeness

Adaptation Dye-Job: Alura is always depicted as a blonde in the comics and most adaptations. Here, she's an Aloof Dark-Haired Girl.
Aloof Dark-Haired Girl: She has a composed demeanor.
And Starring: Is credited with "Special Guest Star" citation.
Ascended Extra: Due to this show being about her daughter, her significance gets bloated. Even compared to the comics and most adaptations where her husband Zor-El is always the prominent of Kara's parents.
Back for the Dead: She is shown as one of the first casualties of the antimatter wave. She returns to help Jon Kent evacuate.
The Beautiful Elite: One of the highest authorities on Krypton, a member, albeit by marriage, of one of its most respected families and strikingly beautiful to boot.
But Now I Must Go: Understandibly, she leaves her daughter to return to Argo once again after the Worldkillers are dealt with.
Cain and Abel: Sentenced her own sister Astra to captivity in the Phantom Zone. Subverted as she later admits to her that she sees this action as sparing her a death in the coming destruction of Krypton that Astra tried so hard to prevent.
Celebrity Paradox: The Law & Order franchise is mentioned to exist within the Arrowverse. Her original actress was a Recurring Character in Law & Order: Special Victims Unit during its 13th to 16th seasons.
Character Death: Despite having secretly survived Krypton's destruction, she is killed for real when Argo is obliterated by an anti-matter wave.
Cool Aunt: based on everything we know about her, and Kara's dreamscape in "The Girl Who Has Everything," in which she shown treating him with great kindness, there is no doubt that she welcomed Clark/Kal-El with open arms and affection to Argo City during his Lois' visit.
Expy: Seems to fill the role that her brother-in-law, Jor-El - and, later, sister-in-law, Lara - had in the Christopher Reeve Film/{{Superman|Film Series }} movies. Superman's parents do appear in the pilot, but they have no lines and do nothing beyond launching their son's ship.
Face Death with Dignity: She's really calm in her final hours, aside from solemnly embracing her husband while watching her daughter's escape pod jettison off to the unknown. It's later revealed that she believed she deserved to die in Krypton's destruction for not doing enough to stop it.
Graceful Ladies Like Purple: She wears an indigo dress in the holograms, and she's definitely graceful.
Hello, Attorney!: Judge actually, but is nonetheless good-looking. Mon-El even complements her appearance.
Hologram: Appears to Kara in a pre-recorded pep talk. And again as a personality module in DEO's headquarters.
Honor Before Reason: Alura allowed the entire world to die in service of the law. Though a flashback in "Bad Blood" shows she believed Krypton will explode, and is determined to get the word out through the law. But ultimately failed.
My Greatest Failure: In private with Astra, she admits her unwillingness to believe her sister until it was too late, thus keeping up the appearances, while simultaneously dooming Krypton, to be this.
Not Quite Dead: Turns out she survived Krypton's explosion and is now on Argo City.
Obnoxious In-Laws: It is not so subtly implied that she had no love for her brother-in-law, Non. Justified due to Non's antagonism, though.
Parents as People: After Astra's confession of the true work she did with Non, Kara is livid when she believes Alura could have prevented the destruction of Krypton, and the death of everything she loved.
Posthumous Character: Died in the pilot, but carries on as an interactive hologram. Until it turns out late in Season Three that she and the rest of Argo City actually survived the destruction of Krypton.
Raven Hair, Ivory Skin: Her her second actress notably has a much paler skin than the original, and is equally beautiful.
Related in the Adaptation: The show's version of Non becomes her brother in law.
Remake Cameo: Her second actress played Smallville's version of Lois Lane.
Sacrificial Lion: She's one of the first casualties of the Crisis on Infinite Earths.
Spared by the Adaptation: She survives Krypton's explosion unlike in the comics.
Stacy's Mom: Mon-El outright calls her a babe, under the misinformed implication that it is a respectful connotation for a beautiful woman.
Statuesque Stunner: She's one of The Beautiful Elite and is 5'8" tall.
Theme Twin Naming: Alura and Astra.
Virtual Ghost: The hologram installed at the DEO is an interactive program taken from Kara's pod, unlike her first hologram which was just a recording.

Zor-El

Species: Kryptonian

Portrayed By: Robert Gant (Supergirl Season 1-2), Jason Behr (Supergirl Season 6)

Voiced by: Roberto Mendiola (Latin-American Spanish dub, Season One), Jorge Palafox (Latin-American Spanish dub, Season Two)

First Appearance: "Pilot" (Pilot 1x1)

Appearances: Supergirl | Invasion!^note(Supergirl)

A prominent scientist in Krypton and Kara's biological father.

see Superman Film Series for the Earth-96 character who bears his name and background

see Smallville: Kryptonians for the Earth-167 character who bears his name and background

Age Lift: He's the older brother of Jor-El here, but it's the other way around in the source material and every other adaptation. Subverted post-Crisis, which made their ages Truer to the Text.
Back from the Dead: Post-Crisis reverses his death, making him stuck in the Phantom Zone instead.
Demoted to Extra: He's usually the most prominent of Kara's parents. After all, he is the one related to Superman by blood. Here, he's nothing but a Satellite Character to Alura, whose conflict with her Evil Twin are directly tied to the first season.
Dies Differently in Adaptation: He dies in an offscreen Heroic Sacrifice to ensure Argo City would function instead of during Krypton's explosion.
Exact Words: When Kara calls out a hologram of Zor-El for having come up with the concept behind the Medusa Virus, citing how her father lied to her about saving lives, the hologram specifically states Zor-El did so to protect Kryptonian lives.
Face Death with Dignity: He's really calm in his final hours, slightly more-so than his wife, holding her in a comforting embrace in their final moments while watching their only child depart to who knows where.
Hologram: Like Alura, one of Zor-El is installed for the Fortress of Solitude.
Lethal Chef: A flashback to Kara's childhood shows Alura apologizing for working late because it meant Zor-El had to make dinner.
Not Quite Dead: Subverted. He survived his supposed death during Krypton's explosion, then he eventually died for real to provide Argo City with a safe environment.
Obnoxious In-Laws: It is not so subtly implied that he and his wife had no love for their brother-in-law, Non. Justified due to Non's antagonism, though.
Parents as People: Much like Alura, Kara loved her father with all her heart, but also respected him a great deal, believing his work to be in the name of life. She is thus taken aback when she learns that he had bio-engineered the Medusa virus, as a weapon against invaders.
Posthumous Character: Died with his wife Alura in the pilot during Krypton's explosion. Or so everyone thought, as they actually survived thanks to a force field he created to protect Argo City; however, he later gave his life to provide them with a working atmosphere, so he's still dead by the time Kara is reunited with her mother. Post-Crisis undoes this, maing him stuck in the Phantom Zone instead.
Related in the Adaptation: The show's version of Non becomes his brother-in-law due to the latter being married to his wife's twin sister.
Satellite Character: To Alura, who gets more screen time and plot relevance. The inverse of how Jor-El and Lara are treated in all the Superman movies. Similar to the post-Infinite Crisis/pre-New 52 comics.
Science Hero: Zigzagged; Kara believes her father was this when he mentioned his work help saved lives, but Zor-El's hologram states his joint project with the Kryptonian military was to develop a viral deterrent that kills extra-terrestrial invaders who might threaten Krypton.
Spared by the Adaptation: Double Subverted. He survives Krypton's explosion unlike the comics but still dies offscreen in a Heroic Sacrifice between the explosion and The Present Day. Then a major Cosmic Retcon happens and nagates said death.

Jor-El

Species: Kryptonian

First Appearance: "Pilot" (Supergirl 1x1)

Appearances: Supergirl

A prominent scientist in Krypton. He was Zor-El's younger brother, Superman's biological father, and Kara's paternal uncle.

see Superman & Lois page for his counterpart in the Superman & Lois universe

see Superman Film Series for the Earth-96 character who bears his name and background

see Smallville: Kryptonians for the Earth-167 character who bears his name and background

see DCEU: Krypton for the character in an undesignated Earth who bears his name and background

Age Lift: He's the younger brother of Zor-El here, but it's the other way around in the source material and every other adaptations. Subverted post-Crisis, which made their ages Truer to the Text.
Cool Uncle: It's clear Kara loved and admired her uncle very much as she always speaks of him in the highest regard.
Deceased Parents Are the Best: He provided his son (and by extension niece) with an awesome fortress.
Demoted to Extra: He's usually the most prominent posthumous member of the House of El in the comicbooks and adaptations, though this is justified since the show is about his niece rather than his son.
Face Death with Dignity: He's really calm in his final hours, holding his infant son in a comforting embrace with his wife.
The Ghost: He can appear in a Hologram much like his brother and sister-in-law but it's never.
Posthumous Character: Died with his brother, wife, and sister-in-law Alura in the pilot during Krypton's explosion. Or at least he and his wife did. Zor-El and Alura survived the explosion, though the former ultimately died by the time Kara finds out.
Related in the Adaptation: The show's version of Non becomes an extended family of his due to marrying his brother's sister-in-law.
Science Hero: Zigzagged; He was a scientist much like his older brother, but helped him in a joint project with the Kryptonian military to develop a viral deterrent that kills extra-terrestrial invaders who might threaten Krypton.

Lara Lor-Van

Species: Kryptonian

Portrayed By: Ana Franchesca Rousseau

First Appearance: "Pilot" (Supergirl 1x1)

see Doom Patrol (2019) – Other Characters for Valentina Vostok, the Earth-21 character who shares her appearance.

Aerith and Bob: Much like her niece Kara, her name doesn't sound out of place on Earth.
Cool Aunt: Kara always remembers both her and Jor-El with great fondness.
Face Death with Dignity: She's really calm in her final hours, holding her infant son in a comforting embrace with her husband.
Posthumous Character: Died with her husband, brother-in-law, and the latter's wife Alura in the pilot during Krypton's explosion. Or at least she and her husband did. Zor-El and Alura survived the explosion, though the former ultimately died by the time Kara finds out.
Related in the Adaptation: The show's version of Non becomes an extended family of hers due to marrying the sister of her brother-in-law's wife.

Military

General Astra

Astra

Species: Kryptonian

Portrayed By: Laura Benanti

First Appearance: "Pilot" (Supergirl 1x1)

Appearances: Supergirl

A rogue Kryptonian general and Kara's maternal aunt, being her mother's twin isister. She is The Leader of the Fort Rozz forces.

Aerith and Bob: While not as common as her niece Kara and distant relative Lara, her name doesn't sound out of place on Earth.
Alas, Poor Villain: Her death is poignant since it drives home the point that she and Kara are still family and still love each other.
Aloof Dark-Haired Girl: She's very proud and acts apathetic.
Always Identical Twins: With Alura, obviously. She mentions that twins were rare on Krypton, so they had fun confusing their parents.
And Starring: Is credited with "Special Guest Star" citation.
Battle Couple: Since she and Non were part of Krypton's military force, they may have been this in the past.
Big Bad: Of Season One. She leads the coalition of criminals the DEO is trying to capture up until the thirteenth episode.
Cain and Abel: Was sentenced by her own sister Alura to captivity in the Phantom Zone.
Canon Foreigner: Invented for the show.
Celebrity Paradox: The Law & Order franchise is mentioned to exist within the Arrowverse. Her actress was a Recurring Character in Law & Order: Special Victims Unit during its 13th to 16th seasons.
Dark Action Girl: She fights very aggressively.
Disc-One Final Boss: She gets killed off in 1x13, leaving Non and Indigo to take over as the Big Bad Duumvirate.
Even Evil Has Loved Ones: She says she has no problem killing Kara, but in action she is hesitant and Non accuses her of being blinded by love.
Evil Aunt: She orders her underlings to kill Kara as soon as she confirms her identity, putting her firmly in this category. Subverted in her second appearance, where it is revealed that it is mostly an act in front of her troops. Whatever problems she had with Alura, she loved Kara and still does.
Evil Twin: Literally, as she is the Evil Aunt to Alura's Good Parent.
Evil Wears Black: She wears the black Kryptonian military fatigues and is Kara's Evil Aunt.
Expy: Seems to fill the role of a gender-flipped General Zod.
Flying Brick: Like Kara and Superman, possesses the standard Kryptonian powerset while on Earth. Flight, Super-Strength, Super-Toughness, Eye Beams (which like Kara's are blue), etc.
Good-Looking Privates. General, actually, but is nonetheless good-looking.
Identical Twin ID Tag: Her skunk stripe.
Immune to Bullets: Appears to phase through them.
Impaled with Extreme Prejudice: Courtesy of Alex using a Kryptonite knife.
In the Back: Stabbed through the heart by Alex using a Kryptonite blade and dies from it immediately afterwards.
Know When to Fold 'Em: When she is unexpectedly wounded by a Kryptonite knife, she retreats immediately. This also means she takes the weapon with her so that it can be analyzed.
Lady of War: She's seasoned combatant, and her grace from experience shows.
Law of Inverse Fertility: She mentions to Kara in the flashbacks that she treats her like the child she never had, implying this trope.
A Lighter Shade of Grey: Sees herself as this compared to Alura, as her intentions on saving Krypton were good despite her methods, while Alura allowed the entire world to die in service of the law.
No Name Given: Until she reveals herself to Alex, she's just called "The General".
Oh, Crap!: Her reaction to General Lane preparing to torture her with kryptonite.
Only One Name: Only Astra's personal name has been revealed so far. Kryptonian females attach their father's and then their husband's full name to their own, and Astra's father and husband's full names are currently unrevealed (though if comics canon is followed, Alura's father - and therefore hers as well - is named In-Ze.)
Punny Name: A space alien named Astra, which coincidentally is the Latin word for "stars". Also, Kara says she used to teach her about stars, i.e. astronomy.
Ret-Canon: She and Alura are made into a Composite Character in Supergirl (Rebirth) (specifically Alura got her military background), thus technically making Astra a Canon Immigrant.
Right for the Wrong Reasons: When she sees a picture of Alex and Kara together, she thinks they're a lesbian couple. Alex did come out as lesbian in season 2, but her relationship with Kara is of the familial type only: as she explains to Astra, Kara is her adopted sister.
Statuesque Stunner: She's the twin sister of Alura, so she's just as attractive, and is 5'8" just like her sister.
Tall, Dark, and Snarky: She displays an unfettered demeanor towards others.
Theme Twin Naming: Astra and Alura.
Tomboy and Girly Girl: Invoked. She wears trousers and is part of Krypton's military contrasting Alura, who wears a dress and works in a more poised career as a judge.
Trailers Always Spoil: Her name was revealed in a trailer a full week before it was mentioned on the show.
Twin Switch: According to her, she and Alura used to do this to confuse their parents.
Underestimating Badassery: So far Astra finds Kara a bigger danger to her plans more than the more experienced and seasoned Superman, seemingly because he was raised on Earth.
Well-Intentioned Extremist: On two worlds.
- When she learned that Krypton was going to be destroyed because of excessive use of the planet’s core for energy production, she turned to terrorism against the High Council.
- On Earth, the reason for her plans to Take Over the World is that she knows the humans would never willingly agree to the measures she believes must be taken to prevent ecological catastrophe.

General Zod

Dru-Zod

https://static.tvtropes.org/pmwiki/pub/images/hallucination_of_zod.png

Species: Kryptonian

First Appearance: "Nevertheless, She Persisted" (Supergirl 2x22)

Portrayed By: Mark Gibbon

A rogue Kryptonian general like Astra and one of Superman's greatest adversaries.

see Superman Film Series for the Earth-96 character who bears his name and background

see Smallville: Kryptonians for the Earth-167 character who bears his name and background

see DCEU: General Zod for the character in an undesignated Earth who bears his name and background

Adaptation Dye-Job: He's blond here, but he's usually portrayed as a brunet in the comics and other adaptations.
Anti-Climax Boss: For such a major villain in the comics his presence here isn't really felt. He's a Posthumous Character in Supergirl pre-crisis and post-crisis he only appears in half an episode of Superman and Lois where he's Demoted to Dragon to Morgan Edge of all people. His counterpart from Steel's world is a much more significant threat.
Arch-Enemy: Superman considers him to be one of his greatest enemies, along with Lex Luthor. Superman had to kill him to stop him, and it turns out even that doesn't keep him down forever.
Back from the Dead: He's somehow revived in the 31st century and fights the Legion. They beat him using kryptonite.
Disabled in the Adaptation: While never elaborated, his white irises indicate that this version of Zod is blind or has an eye condition, though this may simply be part of the Silver Kryptonite hallucination and not indicative of any infirmity.
Evil Sounds Deep: He has a deep, booming baritone that would do Terence Stamp proud.
Evil Wears Black: He wears the same black Kryptonian military fatigues that Astra and Non wore in Season One.
General Ripper: As mentioned above, he's a Kryptonian general. And if previous adaptations are any indication, he's a tough son of a bitch.
The Ghost: He never appears in person, and we only get to see what he looks like due to Superman's hallucination.
Grand Theft Me: In Superman and Lois, Morgan Edge/Tal-Rho attempts to transplant Zod's consciousness into Superman.
Kneel Before Zod: Invoked in Superman's hallucination, where Zod says the planet will kneel before him.
Large and in Charge: A general who stands 6'5.
Last Episode, New Character: He makes his debut via hallucination in the Season Two finale.
Offscreen Moment of Awesome: His encounters with Superman happened many years ago. However it went down, it ended with Superman killing him.
Offscreen Villainy: Only Superman has experienced his villain credentials. From what we see in his hallucination of Zod, he threatened to destroy Earth and Superman's loved ones.
Prophet Eyes: The irises of his eyes are silvery white. Why exactly is never stated, though that may have been a side effect of the Silver Kryptonite Superman was suffering from while hallucinating Kara as him.
Tall, Dark, and Snarky: He stands 6'5 and is very cruel and imposing.
Villain of Another Story: Is only The Ghost for the series proper, but is implied to have been Superman's most dangerous enemy.

Lt. Col. Non

Non

https://static.tvtropes.org/pmwiki/pub/images/supergirl_non.jpg

Species: Kryptonian

Portrayed By: Chris Vance

First Appearance: "Hostile Takeover" (Supergirl 1x8)

Appearances: Supergirl

A rogue Kryptonian lieutenant and Astra's husband; Kara's uncle by marriage.

see Superman Film Series for the Earth-96 character who bears his name and background

Adaptation Dye-Job: He's blond here, but he's usually portrayed as a brunet in the comics and other adaptations.
Adaptational Intelligence: The original Non was nothing but a silent brute, while this one has intelligence to back up his power. In the post-Infinite Crisis/pre-New 52 comics, he was a scientist until he was lobotomized by the Science Council to silence him of Krypton's impending doom. That aspect of him seems to be Adapted Out in this continuity.
Battle Couple: Since he and Astra were part of Krypton's military force, they may have been this in the past.
Big Bad Duumvirate: Becomes this with Indigo after Astra's death.
Bread and Circuses: Believes humanity is too busy watching celebrity TV shows and running political circuses to acknowledge, much less fix the problems they use popular entertainment to distract themselves from. He also believes Cat, Supergirl, and Maxwell Lord are part of the problem, since their tendency to dominate the headlines helps distract and placate the public from thinking about bigger problems.
Colonel Badass: Word of God confirms that his rank is Lieutenant Colonel.
Commander Contrarian: In spite of his loyalty to Astra, he questions her willingness to eliminate her niece, knowing full well that the Els are a very tight family.
Composite Character: He takes aspects of Ursa (A Krytonian War criminal's spouse), Kru-El (An evil uncle), Mongul (using Black Mercy.)
Disabled in the Adaptation: Non is supposed to be mute, but his constant Motive Rant obviously shows he isn't. Instead, his disability becomes blindness after losing an optical Beam-O-War with Kara.
The Dragon: To Astra.
Dragon Ascendant: After his wife's death, he joins forces with Indigo to form a Big Bad Duumvirate.
Even Evil Has Loved Ones: Although he may act as a Commander Contrarian to his wife, he truly does love her. He openly cries when their underlings mourn Astra's death.
Even Evil Has Standards:
- Despite being rather less willing than Astra to consider humans' lives on the same importance as his, he's still firmly against Indigo's plan to simply wipe them all out... at first.
- When Lucy releases the criminals from Fort Rozz while under the effects of Myriad, he requests that the White Martian stay locked up, stating that it would be better for everyone if it stayed where it was.
Evil Brit: Speaks with his actor's natural British accent.
The Evils of Free Will: Believes humanity will never put aside its own petty self-interests to save the world, so he decides to mind control all of humanity into working together to solve all the world's problems. A slightly more justified version than most, as he and Astra tried to do the same thing on Krypton to stop the Kryptonians from destroying their planet, which they did.
Evil Uncle: He's Kara's uncle, Astra's husband and second in command.
Evil Wears Black: He wears the same black Kryptonian military fatigues that his wife wears.
Eye Scream: The consequences of losing a heat-vision duel to Kara.
Flying Brick: Like every other Kryptonian on Earth.
The Friend Nobody Likes: It is not so subtly implied that members of his extended family have no love for him. Justified due to his own antagonism, though.
Humans Are the Real Monsters: This pretty much sums up his view of humanity.
In Name Only: He's an evil Kryptonian. That's the only thing he shares in common with any of his namesakes.
Interspecies Romance: He was in a relationship with Indigo, an alien from the planet Colu.
Jerkass: He's very unpleasant and condescending by default, not to mention his attempts to control and later exterminate mankind.
Not Even Bothering with the Accent: He's the only recurring character who doesn't sound American^noteHis actor is English. The show hasn't explained this, although it's possible that he came from a noble background.
Not His Sled: In his Superman II debut, he was mute. In his final battle with Supergirl in this show, there's a Beam-O-War with heat vision, and an explosion, and he's clearly injured. ...And then we find that it's his eyes, not his voice, that's now ruined.
Only One Name: Like all versions of him, his last name is not given.
Politically Incorrect Villain: When he saw Astra hesitated in killing her niece, he comments that the women in Astra's family are weak.
Red and Black and Evil All Over: His black outfit has Vermilion accents.
Related in the Adaptation:
- In this version, he becomes Kara's uncle by his marriage to her maternal aunt.
- Inverted with Zod. In the comics and most media, they are Heterosexual Life-Partners. Here, it's implied that they don't even know each other and if they do, it's likely only in a professional level.
Silly Rabbit, Idealism Is for Kids!: He doesn't share Supergirl's faith that humanity can be reasoned with.
Uncertain Doom: Apparently killed by Supergirl in the Season One finale.
Utopia Justifies the Means: He truly believes that using Myriad will make Earth a better place, not just ecologically, but socially as well. Once he gains control of National City, he puts its populace to work fixing not only environmental issues, but issues that plague humanity like famine, disease, hunger, poverty, etc. He also seems happy to have eradicated hatred, prejudice, crime, and war. And before Indigo gets under his skin, it genuinely doesn't occur to him to abuse Myriad for his own power, as he really did have thoughts only to making the world better for everyone in it.
Villain Has a Point: When Supergirl first tries to tell Non that Myriad is not the way to save the planet, he points out that at least he's doing something; Supergirl hasn't once used her powers to save the planet in all the time she's been on Earth, merely saving random citizens in National City. Notably, Supergirl has no direct counterargument.
Well-Intentioned Extremist: While he's more of a ruthless Jerkass about it than Astra, Non really does believe Myriad is the only way to save Earth and humanity from humanity itself.

Civilians

Thara Ak-Var

Species: Kryptonian

Portrayed By: Esmé Bianco

First Appearance: "Not Kansas" (Supergirl 3x21)

Appearances: Supergirl

A citizen of Argo City and a childhood friend of Kara Zor-El, revealed to have survived the destruction of the planet alongside the city's population.

Adaptational Wimp: In the comics she's the superhero Flamebird. The show never gave any hints of her going in that direction.
Celebrity Paradox: While Kara loves Game of Thrones, she doesn't seem to notice that her long-lost best friend happens to look a lot like the show's original Ms. Fanservice character.
Happily Married: By the time Kara meets her again, she has a husband and two children.
Old Friend: Of Kara. They were so close in their childhood that they were able to finish each others sentences.

Daughters of Juru

In General

A heretical cult on Krypton, that was outlawed but thrived in the shadows. Just before Krypton exploded they sent the three Worldkillers to Earth so they could one day conquer the planet and remake it into a New Krypton.

Black Cloak: The witches feel a need to wear conspicuous dark cloaks that marks them as Obviously Evil.
Color Motif: Theirs is red and black, just to hammer the obvious fact that they're a Religion of Evil.
Fantastic Racism: They consider humans to be a lesser species to Kryptonians, so are more then willing to commit exterminate them by terraforming the Earth.
Obviously Evil: They have a red and black Color Motif, are implied to be Blood Magic users, and are always clad in black cloaks.
Religion of Evil: They want to bring darkness into the world.
Science vs. Magic: They created the trio of World Killers not with science but with forbidden dark magic.
Squishy Wizard: They have zero combat experience so when Supergirl and her allies catch them off guard they get knocked out pretty easily.
Wizards from Outer Space: Take Kryptonians and give them dark magic for good measure and you get this trope.

Yuda Kal

Species: Kryptonian goddess

First Appearance: "The Fanatical" (Supergirl 3x19)

Appearances: Supergirl

The Daughters' patron goddess that was replaced by Rao's worship.

Adaptation Name Change: A variation. There was a Kryptonian goddess called Yuda in Pre-Crisis continuity. The series just adds Kal to her name.
Adaptational Villainy: Yuda was a harmless deity associated with the moons and marriage. Here, Yuda is an actually malevolent goddess whose power is used to create the Worldkillers to carry out her will.
Biblical Bad Guy: To Kryptonian lore at any rate, she is explicitly compared to Lilith by Thomas Coville.
Greater-Scope Villain: For the Worldkillers arc considering the witches created them on her orders to spread chaos and disorder. Though she never actively participates in the plot, at one point an Earth-based cult tries to summon her in an episode to take over its leader.
Outside-Context Villain: By the way of Un-person. Nobody was expecting Kryptonian dark wizards answering to her, a nearly forgotten Kryptonian entity.
Un-person: Her cult and nearly all traces of its existence were stamped out as Kryptonians turned to Rao and were almost forgotten by the time Krypton was destroyed. Presumably even more so afterwards, given that most people in a position to know about her were dead.

The Witches

Jindah Kol Rozz

Species: Kryptonian

Portrayed By: Sarah Douglas

First Appearance: "Fort Rozz" (Supergirl 3x11)

Appearances: Supergirl

A priestess from Krypton, imprisoned in the facility that bears her name. She has information about the Worldkillers that Kara is desperate to obtain.

see Superman Film Series for Ursa, the Earth-96 character who bears her physical likeness

Consulting a Convicted Killer: Kara seeks her out, in hopes of getting information about Reign and the other Worldkillers. Reign is sent to ensure she doesn't reveal anything.
The Dreaded: The other inmates are terrified of her, because the people that go down to the level she occupies tend to never come back.
Greater-Scope Villain: As part of the evil cult that created the Worldkillers in the first place, she is ultimately responsible for the danger they pose, but she takes no active role in the plot and is never even fought by Kara before Reign blasts her.
He Knows Too Much: Reign kills her to ensure the Worldkillers' secrets will remain hidden.
In the Back: She gets a hole blown through her by Reign, the moment she turns her back.
Religion of Evil: A Priestess of the cult that created Reign and the other Worldkillers.
Remake Cameo: This is the third time Sarah Douglas has played an evil Kryptonian, having played Ursa in the original Superman films and Mala in the Superman: The Animated Series episode "Absolute Power".
Smug Snake: She is supremely confident of her impending triumph, mocking Kara right up until Reign blasts her with heat vision.
We Hardly Knew Ye: She gets offed by her own cult's creation at the end of her only scene.

Selena

"They will not call you a hero. They will call you Worldkiller. They will try to contain your power but they will fail. You will show no mercy to those who oppose you. Your justice will burn the world of man."

Species: Kryptonian

Portrayed By: Anjali Jay

First Appearance: "The Faithful" (Supergirl 3x4)

Appearances: Supergirl

A priestess from Krypton, part of the same cult as Jindah Kol Rozz, whose holographic AI corrupted Sam into becoming Reign in the first place. She turns out to be alive in Argo City, hiding in plain sight as a member of the High Council.

see Superman Film Series for the Earth-96 character who bears her name and background

see Arrowverse: Other Earths for her counterpart in an unknown, destroyed Earth

Adaptation Dye-Job: The original version of the character is an Evil Redhead. Here, she's black-haired.
Adaptation Species Change: Selena was a human witch in the Supergirl film, but here she is a Kryptonian witch.
Aerith and Bob: Much like Kara and Lara, her name doesn't sound out of place on Earth. She's notably the only one from the Cult of Worldkillers with a normal-sounding name (barring the Worldkillers themselves, who were raised on Earth and given human names). This is because the 1984 Supergirl film character she's adapted from was from Earth.
Bad Boss: Kills Coville once he has served his purpose.
Bitch in Sheep's Clothing: She seems like a devoted public servant to Argo, but in reality she hates her fellow surviving Kryptonians for outlawing her cult and forcing her and her fellow witches to hide their beliefs.
Canon Character All Along: She appears several times throughout Season Three as a sinister, nameless witch who pushes Reign along the path of darkness until she is finally revealed to be this universe's version of the Big Bad from the 1984 movie.
The Corrupter: Selena is the one responsible for forcibly turning the Worldkillers into monsters who disregard their human identities. She even encourages them to kill off all human attachments so that their human sides will die forever.
Evil Counterpart: To Alura, serving as a dark mentor for Reign and even having a hologram of herself to guide her much like Alura has done for Kara.
Evil Matriarch: Since she was one of the witches that created the Worldkillers and their human hosts, she technically serves this role to them, as she is the closest thing they have to a birth mother and is responsible for their loss of humanity.
Fantastic Racism: She really hates humans. When she and her followers get to Earth, one of her first orders is for all humans to be killed. Which is ironic, since in the film, Selena was human!
Faux Affably Evil: She at first appears to be polite and well-spoken, greeting Kara in a friendly manner when they meet, and voting in her favor when the Council must decide whether or not to help Kara. However, after her arrival on Earth, she quickly proves herself to be incredibly nasty and racist towards humans, even killing the perfectly loyal Coville, after he did all of their bidding, no less.
Game Face: The first time Selena appears in the season, she appears as a vision to Sam with a monstrous face (resembling Reign's comics self, no less) in order to prepare her for her transformation as Reign. Suffice it to say it freaks poor Sam out.
Greater-Scope Villain: She's the true power behind the Worldkillers, with her Hologram manipulating them until the Fortress is destroyed. She specifically gets involved in the final few episodes after learning that Reign is on the loose, though the Worldkiller herself is still The Heavy.
Hate Sink: In stark contrast to Reign, Selena quickly establishes herself as a truly nasty piece of work, being incredbily racist towards humans and condescending in general.
Hidden Villain: For most of the season, Selena serves this role, with only the other Worldkillers and Coville aware of her existence (and even then, there's no sign that she's still alive). It's not until the end of the season that she is able to take the stage herself by escaping Argo City and arriving on Earth to bring Reign Back from the Dead.
Hologram: She created a holographic AI of herself to inhabit Reign's Fortress of Sanctuary, though it gets destroyed along with the Fortress.
The Man Behind the Man: She's the true puppeteer pulling Reign's strings; though it seemed to be from beyond the grave, she turns out to be alive and able to contact Reign.
No Name Given: For most of the season, Selena is just an unnamed priestess and holographic AI serving the Worldkillers. It's not until near the end of the season, with the revelation that she is a living, breathing Kryptonian, that we find out her name is Selena and she's actually controlling the Worldkillers.
Race Lift: Selena in the movie was a red-haired Caucasian; this one is black-haired and dark-skinned.
They Look Just Like Everyone Else!: Selena does not look sinister at all (unless she's in her black robes), but she's the one behind the Worldkillers.
Villain with Good Publicity: Her day job is being a member of Argo City's High Council, and she even casts the deciding vote in allowing Kara to obtain the rock she seeks in her efforts to cure Sam of Reign, giving away no hint of her true intentions.

Felra

Species: Kryptonian

Portrayed By: Kerry Sandomirsky

First Appearance: "Not Kansas" (Supergirl 3x21)

Appearances: Supergirl

A seemingly harmless wife of a grocery owner from Argo City, secretly a member of the Daughters of Juru. She unsuccessfully targets Kara and Mon-El.

Bitch in Sheep's Clothing: When initially accused of being behind the construction tower accident, she acts all innocently.
Bond Villain Stupidity: There was really no reason for her to give up Selena's true allegiance prematurely and thus robbing the Cult of the element of surprise.
There Are No Coincidences: Kara rightfully suspects her to be behind the accident at the market and recognizes her thanks to the hood.

Vita

Species: Kryptonian

Portrayed By: Rosemary Hochschild

First Appearance: "Not Kansas" (Supergirl 3x21)

Appearances: Supergirl

Part of the trio of Dark Priestesses, alongside Selena and the unnamed priestess. Seems to be the least intelligent of the bunch.

see Arrowverse: Other Earths for her counterpart in an unknown, destroyed Earth

Dumb Muscle: What Alura describes her as, even being surprised that Selena still keeps her around. Given how she tries to hit an obvious hologram, she might have a point there.

Ayala

Species: Kryptonian

Portrayed By: Winsome Brown

First Appearance: "Not Kansas" (Supergirl 3x21)

Appearances: Supergirl

Part of the trio of Dark Priestesses, alongside Selena and Vita.

Reign

Samantha Arias / Reign

https://static.tvtropes.org/pmwiki/pub/images/samatha.png

"You are the most important thing in the world to me. Never, ever forget that."

https://static.tvtropes.org/pmwiki/pub/images/reign.jpg

"I am no Devil. I am truth, and judgment, and death, and I will Reign."

Species: Enhanced Kryptonian ^note

Portrayed By: Odette Annable

First Appearance: "Girl of Steel" (Supergirl 3x1)

Appearances: Supergirl

The first of the Worldkillers. Upon her adoption, she leads her life under the name "Samantha Arias", but has no idea of her heritage until her latent superpowers begin to emerge.

Adaptational Attractiveness: The comic book version of Reign resembles a female version of Doomsday. Here, she looks like an attractive human woman. Even in full Worldkiller mode, she looks like herself in a costume.
Adaptational Modesty: Her costume covers a lot more than the comics version, being essentially a black version of Kara's suit with the comics Reign's key design elements.
All Your Powers Combined: After the deaths of Purity and Pestilence, she absorbs their essences, gaining their powers.
Aloof Dark-Haired Girl: As Sam, she has a very guarded but ultimately friendly personality. As Reign, she radiates cold confidence and pride.
Always Someone Better: She has all of Kara's powers, only at a much stronger level, and bolsters a strong immunity against all of the typical kryptonian weaknesses. The gap gets even bigger when she absorbs Purity's and Pestilence's powers.
Anti-Villain: She grew up thoroughly unaware of her powers and is in general a quite friendly and likable hard working single mom, openly frightened of the changes her body has been exhibiting, and the cryptic messages of her "reigning" over Earth. Even in Reign mode, she thinks that she's doing the world good by showing its criminal element no mercy.
Back from the Dead: She is resurrected by Selena and her sistren just one episode after her defeat.
Badass Cape: This version of Reign wears a black cape as part of her suit.
Big Bad: Serves as this for Season Three; while there are three Worldkillers, she's their leader, the first to be introduced, the one who receives the most focus and development, and the primary threat throughout the season after her emergence. Even after she's defeated by Kara and Mon-El and her creator, Selena, steps forth, Reign is quickly resurrected in the next episode and, while she does Selena's bidding, is still The Heavy whose defeat is the key to stopping the witches.
Big Bad Ensemble: With Morgan Edge in Season Three, until he's caught and arrested halfway through, leaving her as the sole Big Bad. Then it's revealed Reign is the Dragon-in-Chief to Selena.
Big Bad Slippage: She's the primary antagonist for Season Three, though she starts out as a seemingly normal single mom with no idea of her past or her powers.
Bizarre Alien Biology: Lena establishes that the Worldkillers are genetically human when not in their Worldkiller forms, even though they were born on Krypton from genetic engineering by Kryptonian cultists.
Brought Down to Normal: After Sam destroys her Reign persona, all traces of Kryptonian DNA have left her body and she is now basically human.
Celebrity Paradox: Zig-Zagged. Cisco Ramon made a vicious Take That! to the Transformers Film Series during the Season Two finale of The Flash, and her actress plays a minor character in Transformers (2007). However, the film series is yet to be mentioned on Earth-38 and an Earth-1 Reign is yet to appear.
Contrasting Sequel Antagonist: A big difference from other important villains is that she has a Split Personality.
Deuteragonist: Aside from Kara, Season Three has focused most strongly thus far on Sam's family life, coming into her powers and developing friendships with Kara, Lena, and Alex.
Disc-One Final Boss: Subverted. After Reign is defeated in 3x21, Selena arrives on earth to resurrect her and takes over. However, Selena's plan hinges entirely on Reign, who continues to serve as the actual threat that needs to be stopped.
Dragged Off to Hell: Her ultimate fate. In the dream dimension, she first gets a beatdown from Sam, then is forced to drink from weakening water of the fountain, then the dark spirits show up and drag her into the water.
Dragon-in-Chief: Serves Selena and the Daughters of Juru, but is much more dangerous and powerful than them.
Enemy Within: She acts at this for Sam after her emergence, with the two fighting for control of their shared body. She becomes an Enemy Without after Kara and Mon-El use the Black Rock of Harun-El — this show's version of Black Kryptonite — to separate the two, unaware that Selena can resurrect her.
Evil Cannot Comprehend Good: Reign was specifically created to be a Worldkiller, so she has no concept of compassion or mercy. Sam, on the other hand, values such traits, so she's overtly horrified when she has no choice but to give in to Reign.
Evil Counterpart: Another survivor of Krypton with an AI and a hidden fortress. (The scene of the creation of the Fortress of Sanctuary even looks a lot like the Fortress of Solitude being created in Smallville, with it growing from a crystal thrown into the distance.) She even tears open her top to reveal the costume below it, just like Kara does. However, unlike Kara, she is (unwillingly) evil.
Evil Wears Black: When Reign is fully unleashed, she dons an all-black suit that's similar to Kara's, but with the key design elements from her own costume in the comics (single armored shoulder pad, armored gauntlets and boots, and a V-shaped belt) as well as her cult's insignia.
Fighting from the Inside: Once Sam becomes aware of Reign's presence in her body, she becomes determined to destroy her evil alter ego. Unfortunately, this goes both ways; Reign decides that she needs to kill Ruby in order to sever Sam's connection to her once and for all.
Foil: Sam in so many ways to Clark and Kara. They were raised with love and affection while Sam was "designed". Clark and Kara had loving foster families on Earth; Sam was kicked out by her adoptive mother for getting pregnant. Clark and Kara became heroes of their own free will (though the values of their adoptive families helped); Sam was destined to be a villain, but she wants to be a hero.
Forced into Evil: After activating her Fortress of Sanctuary, a horrified Sam literally has no choice but to awaken as Reign.
A God I Am Not: Although Reign is modeled after a Devil figure from Kryptonian mythology, she doesn't see herself as a deity, only as a bringer of justice.
Happily Adopted: Though things ended badly between the two, Patricia, much like Jeremiah and Eliza Danvers, and Jonathan and Martha Kent, gave Sam a loving and happy childhood.
The Heavy: She's by far the most prominent threat in Season Three and the Worldkiller to receive the most focus and development, despite technically being the instrument of the cult that created her, particularly Selena.
Hope Crusher: Leaves Kara completely hospitalized during their first battle, which shakes up the citizens of National City to the core.
How Do I Shot Web?: She is unwilling to believe she has powers at first, but when she decides to try anyway, she can't activate them.
I Am the Noun: She proclaims herself to be truth, judgment, and death.
Iconic Sequel Character: Wasn't introduced until the Season Two finale, and doesn't make a proper appearance until the Season Three premiere.
Jekyll & Hyde: Sam and Reign share a body, but while Sam is a motherly and benevolent woman, Reign is a vicious Worldkiller.
Knight of Cerebus: When Reign finally makes her full debut in the middle of Season Three, she's revealed to be the subject of an apocalyptic prophecy that indicates Kara will die by her hand. She proceeds to burn her symbol all over National City, brutally execute a number of criminals, and finally trash Kara in a fierce battle; she strikes First Blood without needing a Kryptonite Factor or De-power, and beats Kara so badly that she has to be hospitalized. Every scene with her is played as deadly serious, especially when Kara and the others learn of her Split Personality and race to find a way to save Sam.
Knight Templar: Reign's purpose is to deal out lethal judgment to sinners, before eventually living up to the title of Worldkiller by going Soiled City on a Hill on the planet. She kills every criminal she comes across... as well as anyone sheltering criminals. Or preventing her from killing criminals. Or simply not punishing criminals enough.
Brainiac-5: She attacked a meth lab. The cops came. She attacked the cops.
Laser-Guided Amnesia: After learning of her heritage in the Fortress of Sanctuary and awakening as Reign, she wakes up back in her house with no memory of the past day.
Laser-Guided Tyke-Bomb: She was designed by the cult to be a Worldkiller and sent to Earth along with Clark and Kara. She was supposed to awaken much earlier, but having a daughter delayed the process.
Last Episode, New Character: She makes her debut via flashback in the Season Two finale, though her first proper appearance as an adult happens in the Season Three premiere.
Mama Bear: Her powers awaken when she saves her daughter.
Meaningful Name: Gets this twofold due to the fact that her surname was given as "March" in an earlier press release before being revealed as "Arias" in the show proper, both of which are references to Gods of War. Her first name apparently means something like "God has heard" or "Name of God" by virtue of being the female version of Samuel. So, "God has heard War" or "The name of God is War", basically. Fitting for a character whose comics counterpart was created to be a world-killing superweapon.
My God, What Have I Done?: Sam is left horrified when Lena shows her proof that she is Reign and that she killed so many people.
Nice Girl: Sam is a friendly and caring person who loves her daughter Ruby more than anything, and when she arrives at her Fortress of Sanctuary and hears that she is from Krypton, she gets excited at the thought of being a hero like Supergirl, only to become horrified upon hearing that she is actually programmed as a living weapon.
Raised by Humans: She was sent to Earth right before Krypton exploded.
Red Eyes, Take Warning: Her Reign personality briefly sports these whenever she's awakened, and her heat vision is red instead of the show's usual blue.
Smug Super: Reign believes herself to be superior to Kara, and while she does have an unfair advantage in terms of physical strength, she's not invulnerable to mental attacks.
Superpowered Evil Side: Samantha Arias is a kind woman who barely has a handle on her powers. Reign is a cold, brutal murderer with full control of her powers.
Teen Pregnancy: Sam had Ruby before she was 18, which is the reason for her mother kicking her out of the house.
There Is Another: She managed to escape Krypton's destruction through a pod much like Kara and Clark, but the cousins, their parents, and she herself are initially unaware of her existence.
Tomato in the Mirror: First she learns she is from Krypton, then she is horrified to learn she is a Worldkiller, then she is forcibly turned into said Worldkiller.
Tragic Villain: Big time, since Samantha has absolutely no control over Reign's actions.
Transhuman: She is a trans-Kryptonian, with all the normal Kryptonian superpowers enhanced by magic and genetic engineering.
Traumatic Superpower Awakening: Sam's powers manifest when her daughter is in mortal danger, and the forced awakening of Reign is shown to be incredibly painful.
Voice of the Legion: In addition to wearing a metallic mask, Reign speaks with a distorting echo to hide her identity as Sam. Even after she's unmasked, she keeps the creepy voice.
Wrong Context Magic: Reign has the standard Kryptonian powerset, but powers those abilities through a means other than sunlight. She isn't depowered by a blue giant star even though Kara is, and kryptonite causes her pain but doesn't negate her abilities.
Zorro Mark: Reign burns her symbol everywhere with her heat vision.

Purity

Julia Freeman / Purity

https://static.tvtropes.org/pmwiki/pub/images/vlcsnap_2018_02_25_13h01m26s672.jpg

Species: Enhanced Kryptonian ^note

Portrayed By: Krys Marshall

First Appearance: "Fort Rozz" (Supergirl 3x11)

Appearances: Supergirl

The second of the Worldkillers.

Bizarre Alien Biology: Lena establishes that the Worldkillers are genetically human when not in their Worldkiller forms, even though they were born on Krypton from genetic engineering by Kryptonian cultists.
Canon Foreigner: She appears to be completely original, as there is no Worldkiller with that name or powerset in the comics.
Dying as Yourself: Julia is able to regain control of her body long enough to kill Pestilence and dies as a human rather then a Worldkiller.
Evil Wears Black: When Purity is fully unleashed, she dons a black suit similar to Reign's, but with brown patterns on the sides and without a cape.
Eye Colour Change: Purity has eerie white irises as opposed to Julia's natural brown.
Forced into Evil: She was living an ordinary life until her powers awakened and her programming as a Worldkiller took over.
Heroic Sacrifice:Her regaining control of her own body to help our heroes fight the Worldkillers ends up being this, as she's mortally wounded by Pestilence and manages to take the bitch down with her.
Kick the Dog: Purity really enjoys being cruel to people. When she has Kara in a headlock, she gloats about how Julia will be Forced to Watch as she kills the beloved heroine.
Make Me Wanna Shout: Her powers revolve around sound manipulation, either as a wide-area Brown Note or a concentrated scream.
Meaningful Name: Her normal self is the most genuine and "baggage-free" of the three Worldkillers. She also dies free of control from her Superpowered Evil Side.
No Good Deed Goes Unpunished: Her powers and Worldkiller personality are awakened when she pushes her friend out of the way of a speeding car and gets hit instead.
Raised by Humans: She was sent to Earth right before Krypton exploded.
Smug Snake: In stark contrast to the friendly and well-meaning Julia, Purity oozes arrogance and self-righteous gloating, even to the point of lying and claiming that Julia was just a part she played all her life, only to reveal the truth when she has Kara in a headlock.
Superpowered Evil Side: As with Sam, Julia is a kind, normal woman, while Purity is a Kryptonian super-weapon created to assist Reign.
Taking You with Me: After being fatally stabbed by Pestilence, Julia uses Purity's sonic blasts to kill Pestilence before she goes.
Traumatic Superpower Awakening: Her powers awaken when an accident leaves her pinned between two vehicles.
Tragic Villain: Same deal as Sam being plagued by Reign.

Pestilence

Dr. Grace Parker / Pestilence

https://static.tvtropes.org/pmwiki/pub/images/screenshot_20180430_225647_video_player.jpg

Species: Enhanced Kryptonian ^note

Portrayed By: Angela Zhou

First Appearance: "For Good" (Supergirl 3x12)

Appearances: Supergirl

The third and last of the Worldkillers.

A God Am I: Says this outright about having the power to choose who dies.
Adaptation Name Change: Due to her ability to control viruses, toxins, and plagues, she appears to be the show's version of Perrilus, who was one of the Worldkillers in the comics (and was a huge green-skinned alien creature rather than an attractive brunette woman). This is backed up by her Supernatural Gold Eyes when she finally appears.
Aloof Dark-Haired Girl: She has black hair and is the most evil and dangerous of the Worldkillers, at least until Reign absorbs her powers and sets out to kill Ruby.
Asshole Victim:
- Grace/Pestilence is the only one of the Worldkillers who fully embraces her Superpowered Evil Side and her status as a tool of mass murder, and she ends up being killed by Julia in response.
- Even before that, her human self Grace's reward for not resisting Pestilence is death in the dark valley dimension.
Bizarre Alien Biology: Lena establishes that the Worldkillers are genetically human when not in their Worldkiller forms, even though they were born on Krypton from genetic engineering by Kryptonian cultists.
Combat Medic: A nefarious Deadly Doctor who is a Physical God.
The Dreaded: All three of the Worldkillers are dangerous to be sure, but Pestilence is the reason for the Bad Future from whence the Legion have come and the reason they deliberately came back in time to change things; they're desperate to kill her in order to prevent the Blight.
Deadly Doctor: Grace is a surgeon by occupation and embraces her nature as a Worldkiller.
Early-Bird Cameo: She appears in the background of a nightmare Kara suffers that allows her to identify Purity on sight, though she's obscured to hide her identity.
Eldritch Abomination: She starts out as a Humanoid Abomination, but by the Legion's time, she has evolved into a living plague called the Blight. Even in Kara's time, her presence is heralded by rivers of blood and birds falling dead from the sky, like some living apocalypse.
Evil Wears Black: After uniting with Purity, Pestilence dons her own version of Reign's black suit, though it's missing the cape, has dark blue patterns, and exposes part of her upper arms.
Face–Heel Turn: Grace started out wanting to save people like most doctors, but not always being able to made her decide it wasn't worth it. Now she likes being able to choose who dies instead.
Femme Fatalons: She can grow her fingernails into talons dripping with her virus, sharp enough to cut Supergirl's skin. Her fingerless gloves emphasize them.
Fully-Embraced Fiend: Unlike Sam and Julia, Grace actually enjoys being Pestilence.
Not Brainwashed: To everyone's surprise, Grace revels in her true nature as a Worldkiller and doesn't want to be saved.
The Plague: As the name might suggest, her power appears to involve a plague of some kind, given the threat her future self poses when she "evolves" into the Blight that the Legion of Superheroes are trying to stop. In the present, birds die en masse when she awakens, though humans have to be infected by skin contact.
Raised by Humans: She was sent to Earth right before Krypton exploded.
Redemption Rejection: In stark contrast to Sam and Julia, Grace doesn't want to be saved from her alter ego — she sees having the power to kill whomever she pleases as the best thing that's ever happened to her.
Smug Smiler: While she doesn't radiate as much arrogance as Reign or Purity, she still likes sporting this.
Superpowered Evil Side: Sadly subverted; Grace is very much aware of her true nature by the time Supergirl and the DEO find her, and she embraces it.
Token Evil Teammate: She's the only Worldkiller who's just as evil as her Superpowered Evil Side, if not more so.
Touch of Death: Anything she cuts with her nails is infected with a deadly virus. Not even Kara is resistant to it.
We Hardly Knew Ye: Grace/Pestilence dies the episode after she's introduced to the show, courtesy of Julia regaining control of her own body from Purity and blasting her point-blank with a sonic scream.

Mars

White Martians

Unnamed White Martian (Season One)

https://static.tvtropes.org/pmwiki/pub/images/supergirl_white_martian.png

Species: White Martian

Known Aliases: "Miranda Crane"

Portrayed By: Tawny Cypress (as Senator Miranda Crane)

First Appearance: "Strange Visitor From Another Planet" (Supergirl 1x11)

Appearances: Supergirl

A Martian looking for another one of its own on Earth but from a different race as J'onn.

Arch-Enemy: He and his race are this to J'onn J'onzz since they killed the latter's entire race including his family.
Defiant to the End: Even while captured, he doesn't stop taunting Kara.
Disguised Hostage Gambit: Literally. He disguised himself as Senator Crane (the person he kidnaps) so he will be put under DEO custody and find J'onn.
The Dreaded: Even Non is afraid of his chaotic nature.
Fantastic Racism: Looks down on Green Martians and humans.
Fingore: He loses a finger during his escape from the DEO.
Gone Horribly Wrong: After being captured, he swears that more will be coming to rescue him. The following season, more White Martians do appear, but not to rescue him. They came for M'gann, and they both ended up dead. And those who came with M'gann in the Season Two finale are sympathetic to the Green Martians, which means they will likely not let him out.
Light Is Not Good: A White Martian. Suffice to say, he's not a very pleasant being.
Lightning Bruiser: He's big, fast and strong.
A Nazi by Any Other Name: He and his kind kill the ones they deem "inferior" to their race.
No Name Given: His real name is never revealed.
No One Gets Left Behind: After being captured, he swears that more will be coming to rescue him. So far, though, he's been proved wrong.
Obviously Evil: Despite the white skin, he's sports a hideous design that wouldn't be out of place in a horror film.
Sweet Polly Oliver: His chosen disguise is that of female Senator Crane.
Voluntary Shapeshifting: He can change forms.
Wounded Gazelle Gambit: After his disguise is blown, he goes back to his lair and pretends to be Miranda Crane again, kept alive by the White Martian. It isn't until Hank finds the real one that they realize they've been played, and by then it's too late to stop the White Martian from taking Alex.

M'gann M'orzz

M'gann M'orzz / Miss Martian

https://static.tvtropes.org/pmwiki/pub/images/miss1.jpg

In her human disguise.

https://static.tvtropes.org/pmwiki/pub/images/miss2.jpg

In her Green Martian form.

https://static.tvtropes.org/pmwiki/pub/images/whitemartian.jpg

In her true form as a White Martian.

Species: White Martian

Known Aliases: Ms. Martian, The Last Daughter of Mars, "Megan", "Supergirl"

Portrayed By: Sharon Leal, Melissa Benoist (as Supergirl)

Voiced By: Azul Valadez (Latin-American Spanish dub)

First Appearance: "Welcome to Earth" (Supergirl 2x3)

Appearances: Supergirl

A survivor of Mars who is a bartender at an alien dive bar.

see the Smallville: Clark's Allies page for the Earth-167 character who bears her name and background

Action Girl: She frequents Roulette's Fight Clubbing. Judging from Roulette's comments and the crowd's reaction, she has a fierce reputation there.
Adaptational Ugliness: In the comics and most adaptations, Miss Martian's Green Martian form is depicted with much more human appearance compared to J'onn's, notable since she has hair. Here, her Green Martian form is a straight-out Gender Flip of the male ones which lacks the hair.
Age Lift: She's usually depicted as a teenager (at least in appearance) compared to J'onn. Here, she's played by an actress only a few years younger than the actor playing the latter.
Alliterative Name: As both M'gann M'orzz aka Miss Martian.
Aloof Dark-Haired Girl: She is very distant and her human form has dark hair.
…And That Little Girl Was Me: M'gann tells J'onn she was a Green Martian aided by a female White Martian who "broke ranks" to help her escape to Earth 300 years ago from the horrors of the worst internment camp. Actually, she is that White Martian, who fled because she couldn't stand for the atrocities her kind committed.
Arranged Marriage: With Armek, whom she bonded with life as mates as per White Martian custom, though it was not her choice, and she outright despises him.
The Atoner: When she turned against the other White Martians, she tried to free every Green Martian she could and get them to safety, only to get found out and barely escape alone. She's been beating herself up for it ever since, and J'onn's arrival in her life starts her down the path to making up for it with acts of kindness.
Awful Wedded Life: She was stuck in an Arranged Marriage with Armek, whom she despises.
Beware the Nice Ones: She is genuinely a kind and loving individual, who took part in Roulette's alien death fights to earn a more stable living than just bar tending.
Composite Character: M'gann and J'onn in the comics have always possessed an uncle-niece dynamic, while this version is a romantic couple; this gives M'gann many similarities to Cha'rissa, a White Saturnian with whom J'onn shared a brief relationship. M'gann is a White Martian who entered a romantic relationship with J'onn, Cha'riss is a White Saturnian, a genetic offshoot of the White Martians. Both of their relationships with J'onn were put on hold in the pursuit of ending their people's civil wars: Cha'rissa is a princess and entered an Arranged Marriage with Jemm, Son of Saturn in order to end the Red/White Saturnian Civil War and M'Gann returned to Mars to finally end the Martian Civil War.
Decoy Backstory: When she first appears, M'gann M'orzz claims that she's a Green Martian refugee who escaped from a White Martian prison camp. It's later revealed that she's a White Martian who fled after developing sympathy for the Greens.
Fight Clubbing: M'gann moonlights in one as "Miss Martian".
Green-Skinned Space Babe: Subverted in that she's pretending to be one. As a White Martian, she's... not so cute.
Guilt Complex: It is heavily implied that her self-loathing stems from her own kind's oppression (and possibly her part on it).
Hero of Another Story: Her resistance against the White Martians mostly happens off-screen.
Iconic Sequel Character: Doesn't show up until Season Two.
I Have Many Names: M'gann also goes by "Megan" (a human derivation of her name) and Miss Martian.
Lady of War: She's still graceful while fighting.
Light Is Good: Is a White Martian, and unlike most of her race, she is a good person who tries to atone for the base atrocities of her species.
Movie Superheroes Wear Black: Is wearing a black costume similar to her Young Justice (2010) incarnation's stealth outfit.
My Species Doth Protest Too Much:
- M'gann does not display the fascism and genocidal tendencies exhibited by White Martians; in fact, she is disgusted by it.
- She ends up leaving Earth to try to find other White Martians who feel the same way.
Promotion to Love Interest: In the comics, J'onn had a paternal relationship with M'gann. In this series, it becomes romantic.
Race Lift: As with J'onn, her human guise is black instead of white.
Red Herring: J'onn thinks she didn't want to Mind Meld with him because of her side job Fight Clubbing. Actually, she didn't want him to know about her being a White Martian.
Related in the Adaptation: Miss Martian and Armek were never married in the comicbooks.
Secret-Identity Identity: She's actually a White Martian who chooses to appear as a Green Martian.
Screw the Rules, I'm Doing What's Right!: It is heavily implied that the reason she left Mars is because she couldn't stand her own kind's oppressiveness.
Sixth Ranger: Has allied with the DEO from time to time.
Spirit Advisor: Appears to J'onn in his coma, urging him that his friends need his help in the midst of the Daxamite invasion.
Token Good Teammate: To the White Martians. Since they are universally an Always Chaotic Evil race, she's branded as a pariah. Later she is able to find others like her, and forms something of a rebellion.
Token Heroic Orc: She did not approve of her own kind's cruelty back when she was on Mars.
Wham Line: "My name is M'gann M'orzz. I'm the Last Daughter of Mars."
Wham Shot: At the conclusion of "Survivors", M'gann morphs into her true form as a White Martian.
You Are Better Than You Think You Are: On the receiving end of this from J'onn in "Survivors".

Appearances: Supergirl

M'gann's former husband sent to Earth to capture to take her back to Mars. M'gann regarded him as the worst of their kind.

Lightning Bruiser: He's big, fast and strong.
Marital Rape License: Not directly stated, but more than subtlety implied by M'gann in regards to their Arranged Marriage. When he approaches M'gann in the bar, he leers that "the nest has been cold" since she left, to which M'gann retorts that it always was.
A Nazi by Any Other Name: He and his kind kill the ones they deem "inferior" to their race.
Obviously Evil: Despite the white skin, he sports a hideous design that wouldn't be out of place in a horror film.
Odd Name Out: Uniquely among named Martians, his name is both only a single word and doesn't use an apostrophe.
Only One Name: Which makes him stand out among his fellow (Green and White alike) Martians.

Portrayed By: Chyler Leigh (as Alex Danvers)

First Appearance: "The Martian Chronicles" (Supergirl 2x11)

Appearances: Supergirl

A Martian sent to Earth along with Armek to look for M'gann.

Alone with the Psycho: After the D.E.O. finds out that Armek was impersonating Winn, everyone in the building splits off into teams to find the real Winn. J'onn and M'gann pair up to search one area while Agents Vasquez and Demos search the north wing, leaving Kara and Alex to search the basement. Unfortunately for Kara, J'onn and M'gann found the real Alex. Cue this character's Trash Talk.
Ambiguous Gender: Other than disguising as Alex, this White Martian's gender is never revealed.

There Is Another: When the D.E.O. is fighting Armek, they think he's alone. Cue The Reveal when the real Alex is found unconscious.
Trash Talk: This White Martian really gets a kick out of insulting Kara while fighting her disguised as Alex.
White Martian!Alex: What's wrong, Supergirl? Too afraid to put up a fight? To tell you the truth, I'm glad they found your sister. It's so exhausting pretending to care about your silly little feelings.
Kara: If you hurt her—-
White Martian!Alex: You'll what? Whine at me?
Voluntary Shapeshifting: Can change forms.

Till'all

Species: White Martian

Portrayed By: Dewshane Williams

First Appearance: "Far From the Tree" (Supergirl 3x3)

Appearances: Supergirl

A member of the White Martian Resistance.

Anti-Hero: Willing to use Mind Rape on J'onn's father in order to get to the Staff of K'lar, and has quite the hostile temperament in general. He mellows out a bit later, however.
Token Heroic Orc: He is part of the White Martian Resistance, a small group that fights against the genocidal majority of his people.

Unnamed White Martian (Season Five)

Species: White Martian

Portrayed By: Unknown

Appearances: Supergirl

A White Martian that came to Earth alongside Malefic J'onzz.

Villainous Friendship: With Malefic, who seems quite affected by his sudden demise.
We Hardly Knew Ye: He only appears in two scenes and is unceremonously shot in the second one.

M'yrnn J'onzz

https://static.tvtropes.org/pmwiki/pub/images/spg315a_0144b.jpg

^{Click here for his Martian form.}

Species: Green Martian

Portrayed By: Carl Lumbly

First Appearance: "Far From the Tree" (Supergirl 3x3)

Appearances: Supergirl

J'onn's father and the former spiritual leader of the Green Martians. He survived two hundred years of torture by the White Martians before being found by M'gann's rebel army.

Authority Sounds Deep: His voice is even deeper than his son's, especially in his native form, and it only adds to his air of authority.
Dies Differently in Adaptation: He dies in a Heroic Sacrifice to save Earth instead of being slaughtered in Mars as part of a Death by Origin Story for J'onn.
Disabled in the Adaptation: The Fictional Disability mentioned below is original to the show.
Fantastic Racism: He hates the White Martians for what they did to his family and planet; at first, he dismisses M'gann's resistance as nothing more than an Enemy Civil War, before he realizes they are sincere in wanting to atone for their kind's atrocities.
Fate Worse than Death: Being kept alive while his family and species were slaughtered, then being tortured for nearly 200 years afterwards.
Fictional Disability: He is suffering from an alien degenerative illness that is effectively the Martian version of Alzheimer's disease.
Fish out of Water: Has some problems adjusting to life on Earth, for understandable reasons.
Funny Foreigner: Of the Alien variety. His Fish out of Water charactization sometimes makes him unfamilar with common phrases which he tends to take literally much like many common examples of this trope. When Alex suggest he and his son have a housewarming party he thinks it has to do with the apartment’s temperature.
Heroic Sacrifice: Sacrifices himself in the Season 3 finale to stop Reign from destroying the planet.
High Priest: Before the massacre of the Green Martians, M'yrnn was their spiritual leader, and still devoutly follows H'ronmeer.
It's All My Fault: Blames himself completely for Malefic's betrayal after Malefic is sentenced to the Phantom Zone, near to the point of suicide.
"He was my boy.. my child! He could not control his illness! The test was mine, and I failed!"
I Have No Son!: Subverted — he initially believes J'onn to be a White Martian in disguise even after J'onn brings him to their old home, and slaps J'onn once out of heartbreak and rage over it. He does eventually open his mind to see the truth, though.
Not Quite Dead: For the longest time, J'onn thought he was the last Green Martian left until he's reunited with his father, and likewise with M'yrnn.
Real Men Love Jesus: As a (or the) high priest, he's very devoted to his god, H'ronmeer — which is why the White Martians kept him alive, as they seem to worship the same god.
Remake Cameo: His actor voiced J'onn J'onzz in the DC Animated Universe.
Spared by the Adaptation: Usually a Posthumous Character in most Martian Manhunter stories, this version is revealed to be Not Quite Dead. Subverted when it is eventually revealed that he is dying due to deteriorating health, and ultimately dies via Heroic Sacrifice.
Your Days Are Numbered: His illness is fatal, and he knows it. Cruelly enough, he becomes a lot more lucid than before in it's final stages.

Malefic J'onzz

https://static.tvtropes.org/pmwiki/pub/images/the_boy_9.png

https://static.tvtropes.org/pmwiki/pub/images/malefic2.png

Species: Green Martian

Portrayed By: Phil LaMarr, Ellexis Wejr (as Mallory), Azie Tesfai (as Kelly Olsen), Chyler Leigh (as Alex Danvers), Sean Astin (as Pete Andrews)

First Appearance: "The Quest for Peace" (Supergirl 4x22)

Appearances: Supergirl

J'onn's long-forgotten brother, who was imprisoned in the Phantom Zone centuries ago for selling out his race to the White Martians.

Adaptational Heroism: In the comics, Malefic was born with the Green Martian telepathy and weakness to fire but when he abused his telepathic powers by mentally attacking his brother’s wife, he was stripped of this ability and his memory of it, thus being led to believe that he was born without telepathy. Here, he was born without the ability to link to the Green Martian Hive Mind, was picked on by the other kids for it, and after retaliating with his ability to take control of the minds of kids, his father unwittingly made matters worse by isolating him, and when this led to Malefic allying with the White Martians, J’onn wiped Malefic’s existence from his father’s mind because the father was contemplating suicide! Thus, Malefic is far more sympathetic here and eventually, makes a Heel–Face Turn.
Adaptational Name Change: In the comics, his given name was Ma'alefa'ak, and Malefic was a moniker he took when he arrived on Earth.
Age Lift: In a fashion. In the comics, he was J'onn's Evil Twin brother; in the show he's J'onn's younger brother.
Arc Villain: He's the main antagonist for the first 4 episodes of Supergirl's 5th Season after which he is seemingly sent to the Phantom Zone, but secretly retrieved by Lena Luthor who uses him as a means to an end for forcing peace on the world.
Badass Cape: He has a long and flowing black cape made out of some sort of shiny, silky material that billows easily, making him look extremely intimidating. As if he isn't already intimidating enough with his ability to control people against their will.
Bad Powers, Bad People: Has the power to "Incept" where he can take control of a persons mind.
Cain and Abel: With J'onn. J'onn was M'yrnn's perfect son, the older of the two and a noted Manhunter. Malefic had to be locked away in a room because it was too dangerous for him to interact with society. Understandably, their dynamic ended up damaged.
Celebrity Paradox: Brainy makes a Shout-Out to Avatar: The Last Airbender in a Season 5 episode by mentioning "Earth- bending". Malefic's actor voiced the Earth King in that series.
Les Collaborateurs: He betrayed the Green Martians to the White Martians because of the way he was treated for his inability to connect to the Martian hive mind, as well as his inception ability.
Creepy Child: Posed as an unsettling young girl in his debut episode.
Dark Is Evil: Dresses completely in black with a billowing black cape, and constantly associated with dim, dark surroundings when in his true form. He skulks in the dark when he introduces himself to J'onn, and is the Arc Villain of the first quarter of Season 5.
Evil Sounds Deep: Like the other J'onzz men, his voice is very deep, although a bit more nasally and throaty than his brother.
Freudian Excuse: He was bullied as a child by other kids for being unable to properly use the Martian hive mind, which caused him to lash out with his 'inception' ability, hurting them. M'yrnn locked him in a room by himself until early adulthood, and Malefic allied himself with the White Martians because he was desperate to belong somewhere and felt betrayed by his family and culture. And then J'onn completely erased all memory of him from the Martian hive mind.
Heel–Face Turn: After J'onn lets him into his mind, opening his heart and soul to him at the risk of being killed, Malefic realizes that his brother really does love him and forgives him.
Imposter Forgot One Detail: He can perfectly shapeshift and imitate voices, but he can't imitate a person's true self, which is why people see right through him when he poses as somebody close to them.
Names to Run Away from Really Fast: "Malefic" means capable of causing great harm or destruction.
Odd Name Out: The first letter of his name isn't followed by an apostrophe unlike his father and brother.
Put on a Bus: After reconciling with his brother, he leaves for Mars so he can't help the heroes with all of their future threats.
Remake Cameo: His actor previously played numerous other DC Comics characters in other adaptations, most notably the Green Lantern John Stewart in the DC Animated Universe.
Remember the New Guy?: Explained as J'onn had erased all memory of Malefic from the Martian hive mind and from himself as well, after their father was heartbroken to the point of wanting to kill himself over Malefic's betrayal.
Un-person: J'onn erased all memory of him from the Martian hive mind after his betrayal.
Villainous Friendship: With an unnamed White Martian that came with him to Earth. He is pretty distraught when they get killed.

Daxam

Prince Mon-El

see The Legion

Queen Rhea

Rhea

Species: Daxamite

Portrayed By: Teri Hatcher

First Appearance: "Medusa" (Supergirl 2x8)

Appearances: Supergirl

The Queen of Daxam, and Mon-El's mother.

see Smallville: Lanes for Ella Lane, the Earth-167 character who bears her physical likeness

0% Approval Rating: Apparently, as her fleeing troops don't bother to transmat her back to her mothership when every Daxamite on Earth is beginning to feel the effects of lead poisoning even though all the soldiers were picked up.
Abusive Parents: Has her son locked in a brig to force him over to her side.
Action Mom: She's willing to kick ass just to get her son back. Too bad she's absolutely horrible to said son.
Aerith and Bob: Like Kara, her name doesn't sound out of place on Earth.
Aloof Dark-Haired Girl: She is very regal, poised and quite insufferable.
And Starring: Credited with "Special Guest Star" citation.
Arc Villain: For the second half of Season Two, she wants revenge on Earth and Kara for "poisoning" her son.
Ascended Extra: In the comics, Mon-El's mother is barely even a character. Here, she becomes the main villain of the second season.
Asshole Victim: After all the suffering she's caused to everyone around her, no one sheds a tear for her after she is killed via lead poisoning. Not even her own son.
Big Bad: She ultimately surpasses Lillian Luthor as the true nemesis of Season Two.
Brutal Honesty: She really hates sugarcoating the way she sees things.
Canon Foreigner: Downplayed, as Mon-El's mother named Marisa did exist in the comics. However, she was barely existent, and Rhea has so many stark differences she's essentially an original character.
Card-Carrying Villain: She's very proud of being a villain.
Celebrity Paradox: Zig-Zagged. The James Bond film series is explicitly mentioned in the Earth-1 shows, and her actress plays one of the Bond Girls in Tomorrow Never Dies. However, the film series is yet to be mentioned on Earth-38 and an Earth-1 Rhea is yet to appear.
Dirty Coward: She has the temerity to beg Mon-El to save her life as they are both dying from lead poisoning, not wanting to face her gods' judgment on her for all the pain she's caused to everyone around her.
Dual Wielding: She wields a pair of Kryptonite-coated sais when fighting Kara.
Emperor Scientist: In addition to being the Queen of Daxam she is a brilliant physicist and inventor, and using Lena and L-Corp's resources she's able to engineer a device that brings stranded Daxamite ships from throughout the galaxy to Earth.
Entitled Bastard: She pathetically expects Mon-El, whom she constantly abused with zero remorse, to save her life when suffering from lead poisoning in the season finale. It doesn't work.
Evil Is Petty: Her response to Mon-El wanting to stay on Earth with Kara? Plot to conquer the planet to turn it into New Daxam and blame Kara for it because she "poisoned" her son's mind.
Evil Matriarch: Judging by Mon-El's reaction, Rhea's idea of bringing back Daxam to its former glory means bad things. Later she makes it clear she doesn't give a damn about her son's personal happiness, even putting a bounty on Kara's head just to get him to leave Earth, and then murders her husband when he abides by Mon-El's decision to remain on Earth.
Evil Wears Black: Wears a black royal gown and is the more cruel of Mon-El's parents.
Fantastic Racism:
- She really hates Kryptonians — especially after Krypton exploding left Daxam a wasteland. It takes a lot of Kara's willpower to be civil to her.
- It doesn't take her very long to start despising Terrans as well.
Faux Affably Evil: She can be quite charming when she needs to be.
Final Boss: She's the ultimate threat that Kara must defeat in Season Two.
God Save Us from the Queen!: While they both want what, they consider, is best for their family and kingdom, Lar Gand is a Reasonable Authority Figure; Rhea, on the other hand, doesn't take 'No' for an answer, not even from her son or husband.
Hate Sink: A vile scumbag to the core. Everything she does, from sending a bounty hunter after Kara, to not keeping her end of the bargain when she duels to the death with Kara, is done with absolutely despicable and remorseless intent.
Hot Consort: Is heavily implied to have married into the royal family, and may have used her beauty to attract Lar Gand's eye.
Hypocrite: Shown in "Alex". While briefly posing as a human, she tells Lena she's been the victim of lies and betrayal, both things she indulges in herself, for which Lena calls her out on when she learns Rhea is an alien. Furthermore, Rhea love-bombs Lena to trick her into bringing Daxamite ships.
Instant Expert: She adjusts to Earth, learning most of its culture and recent events in a very short time.
"It" Is Dehumanizing: She only addresses Kara as "the Kryptonian girl".
I Lied: When Kara challenges her to the duel, she agrees to the terms: if Kara loses, Rhea will lay waste to Earth while Kara is forced to watch, but if Rhea loses, she will leave and never return. She loses the fight and, surprise surprise, doesn't keep her end of the bargain.
It's All About Me: She wants familial love on her terms, and murders her husband for daring to let Mon-El stay on Earth.
Jerk with a Heart of Jerk: Is a downright horrible person who will do anything to get what she wants, and any kindness she displays is nothing but an act.
Kicking Ass in All Her Finery: She fights wearing her royal gown.
The Kingslayer: Kills her husband for allowing their son to live on Earth.
Klingon Promotion: Her intention for killing her husband is not for the throne^note but due to him going soft on their son, although she ascended as the ruler of Daxam nonetheless.
Lady Macbeth: She is much more assertive than her husband.
Literally Shattered Lives: In the Season Two finale, she turns into stone due to overexposure to lead, then crumbles.
Love Makes You Crazy: If killing her husband just because he was a little more open-minded about their son living on Earth is any indication, then yeah.
Love Makes You Evil: She will cross lines that shouldn't be crossed if it means she can have her son back.
Manipulative Bastard: She's somehow aware of Lillian Luthor and how horribly she treated Lena, and thus is able to use Lena's desire for a caring mother figure to sway her to her side.
Man of Kryptonite: Her blood was laced with kryptonite after Krypton exploded. This comes in handy during her Final Battle with Kara.
My Beloved Smother: She steps over her son's boundaries quite a few times.
Never My Fault: She's incapable of taking responsibility for anything she's done. Everything is because someone else made her do it, and she'll bend over backwards to make herself the victim.
One Head Taller: She's 5'6 while her husband is 6'3.
Red Oni, Blue Oni: She's quite confrontational compared to her more benevolent husband.
Remake Cameo: Her actress previously played Lois Lane on Lois & Clark.
Sanity Slippage: Killing your husband just because he thinks your son may be better off living on Earth for now is not a good sign that a person is mentally healthy.
Screw You, Elves!: Her opinion of Kryptonians, considering them a pretentious, patronizing race.
She Is the King: She becomes Daxam's main ruler after she kills her husband.
Slavery Is a Special Kind of Evil: She doesn't seem to consider slavery evil, however. She views it as making their lives better in service to the royal family.
The Sociopath: She's superficially charming, manipulative, self-centered, and has no empathy for anyone, not even her own son and husband.
Taken for Granite: She turns into stone in the Season Two finale due to overexposure to lead.
Villains Want Mercy: She still has the gall to beg her son to save her when she's dying. Of course, he's having none of it.
Why Are You Not My Son?: She develops a massive respect for Lena Luthor and treats her like she’s her offspring more than she does Mon-El. She even goes as far as to openly voice her affection for her and how much she wants her as a daughter even when her true colours are revealed.

King Lar Gand

Lar Gand

Species: Daxamite

Portrayed By: Kevin Sorbo

First Appearance: "Medusa" (Supergirl 2x8)

Appearances: Supergirl

The King of Daxam, and Mon-El's father.

Age Lift: Due to being a Decomposite Character (see below), he is now old enough to be Superman's father (whom Lar Gand considers as his big brother in the comics).
And Starring: Gets this citation in the guest stars lineup.
Decomposite Character: Lar Gand is actually Mon-El's real name in the comics. Here, he is Mon-El's father.
- Composite Character: King Lar Gand is also mashed-up with Kel Gand, Mon-El's father from the comics.
Even Evil Has Loved Ones: While Lar Gand may not be the poster boy for most benevolent king in existence, when it comes down to it he really wants his son to be happy, in contrast to his wife.
Even Evil Has Standards: His shocked reaction to finding out that Rhea put a bounty on Kara's head shows that he at least has a sense of morality.
Heel–Face Door-Slam: Just after he has stopped in his quest to forcibly bring their son with them and also stopped Rhea from hurting Kara more, he gets stabbed to death by his wife herself.
Informed Attribute: Lar Gand is described by Mon-El as "not a very good man", someone Mon-El would run away from if he ever showed up. On screen, however, Lar Gand is a Reasonable Authority Figure and it's actually his wife that turns out to really deserve that description. (However, he was right along with Rhea for much of his screentime.)
One Head Taller: He's 6'3 while his wife is 5'6.
Reasonable Authority Figure: Zig-zagged. On the one hand he lets his son stay on Earth as he knows that what he really wants; on the other hand he scoffs at Mon-El's suggestion that Daxam become a democracy. Unfortunately for him letting his son stay on Earth is enough of a slight for his wife to murder him.
Red Oni, Blue Oni: He's more benevolent husband compared to his wife who is quite confrontational.
Tall, Dark, and Handsome: He's 6'3 and looks great.
You Have Failed Me: His wife kills him for being more open minded about their son living on Earth.

Colu

Querl Dox

Indigo

Indigo / Brainiac 8

https://static.tvtropes.org/pmwiki/pub/images/snapshot_001.bmp

Species: Coluan

Portrayed By: Laura Vandervoort

First Appearance: "Solitude" (Supergirl 1x15)

Appearances: Supergirl

An alien android from the planet Colu, of the Brainiac clan, who was an inmate at Fort Rozz and Non's ex.

see Smallville: Kryptonians for Kara Zor-El, the Earth-167 character who bears her physical likeness

Adaptational Origin Connection: In this version, she's the reason why Kara and the Fort Rozz inmates came to Earth.
Ax-Crazy: She's a complete psychopath that enjoys one thing and one thing only when it comes to life: ending it.
Adaptational Villainy: In the comics, Indigo is a sub-personality of the villainous Brainiac 8, but wholeheartedly good, which made for one tragic story line; here, Indigo is simply the name Brainiac 8 chose for herself.
A God Am I: Definitely likens herself as this.
And I Must Scream: Non saves her from Winn's virus, but keeps her in pieces to force her into line.
Big Bad Duumvirate: Becomes this with Non after Astra's death.
Composite Character: With elements of Gender Flip. This version of Indigo was involved in the backstory of Krypton like the original Brainiac from the comics, instead of being from the future, and is pure evil like he.
Dark Action Girl: She can put up one brutal fight.
Dragon with an Agenda: While Non is technically in charge, Indigo is perfectly willing to manipulate him into just killing humanity.
The Dreaded: She was considered the single most dangerous inmate in Fort Rozz.
Evil Redhead: Her real form has scarlet hair.
Expy: Visually, this incarnation of Indigo takes inspiration from Mystique's appearance in the X-Men Film Series.
Facial Markings: There's a Brainiac symbol on her forehead.
Femme Fatalons: She has a clawed glove on one hand.
A Form You Are Comfortable With: Before revealing her true nature, she presents herself through television and computer screens as Laura Vandervoort sans makeup.
For the Evulz: Her only motive, she wants to kill entire planets' worth of beings for no reason other because she likes it.
Green-Skinned Space Babe: She's a Human Alien whose skin color is indigo.
Half the Man He Used to Be: Was torn in half by J'onn in the Season One finale.
Interspecies Romance: She was in a relationship with Non, a Kryptonian.
Lady Macbeth: Once she sees Myriad's mind control technology deployed, she starts trying to convince Non to use it to become a Galactic Conqueror.
Large Ham: Indigo has a flair for theatrics even by the standards of this show, and Laura Vandervoort is clearly having a blast chewing the scenery every second she's on screen.
Meaningful Name: Three guesses what the color of her skin is.
Nice Job Fixing It, Villain: She is revealed to have been the one who remotely activated Kara's pod so that it could leave the Phantom Zone as well as linking Fort Rozz's systems to the pod so that the fortress could follow it out. So in essence she is responsible for all the events of the show, and her own downfall.
Omnicidal Maniac: She was imprisoned in Fort Rozz for trying to destroy all life on Krypton, and later tries to exterminate all life on Earth.
Remake Cameo: Her actress was the previous live-action Supergirl.
Robot Girl: Essentially, since she can be repaired and is dependent on technologies.
Rogues' Gallery Transplant: Usually a villain/ally of the Titans.
Rubber Man: She can stretch both of her arms.
The Social Darwinist: She believes that the weak and the inferior should be exterminated so the strong can live unencumbered by them.
- Ultimately a Subverted Trope in that, be it strong or weak races, she just loves kickstarting mass genocides. All for the sake of cruel fits and giggles.
Technopath: She can use any computer as a portal.
Villainous Cheekbones: Indigo's cheekbones are so prominent they could cut glass.
We Can Rebuild Him: After her debut appearance she is left broken apart, but Non is able to reconstruct her. She's ripped in half in the end, but this time, Non's not around to do so; it remains to be seen if she will return.

Brainiac

Vril Dox

Species: Coluan

Portrayed By: TBA

The progenitor of Indigo and Brainy's "clan". Originally dead by the time of the Legion of Superheroes, but after averting the Blight in the past, and saving millions of lives in the future, his, unfortunately was one of those saved. Now all A.I.s in the future are threatened by Brainiac with extinction, preventing Brainy from returning home, and sending Winn in his place to stop him.

see Smallville: Kryptonians for the Earth-167 character who bears his name and background

The Ghost: Never appears on screen, just referred to.
Omnicidal Maniac: Now that Brainiac is alive in the future, he has made it his mission to completely eradicate all artificial life in the universe, using a computer virus he created that specifically targets AI's.
Nice Job Breaking It, Hero: The Legion meant to save lives by stopping Pestilence from evolving into Blight, but never intended Brainiac being one of those saved. Now Brainy can never return home, unless Winn and the Legion can stop his ancestor's AI destroying virus.
Villain of Another Story: He isn't directly seen in the series, but his actions have a profound effect on the future and the actions of the Legion.

Dominion home planet

Dominators (Earth-1)

Dominators

Species: Dominator

First Appearance: "Invasion!" (The Flash 3x8)

Appearances: Invasion! ^note

An Alien Invasion force that engages all of the heroes of the Arrowverse.

Adaptational Badass: In the comics their main threat was being a race of genetic engineers with advanced technology that Earth couldn't directly confront. In the Arrowverse they're also given a range of formidable telepathic abilities and strength enough to stand up to Kryptonians.
Adaptation Deviation: Of a Race Lift sort: post-Crisis, they were normally yellow, not green, with giant red spots on their heads. (The original pre-Crisis Domninators were blue.)
Always Lawful Evil: As with their comic counterparts.
Androcles' Lion: Subverted. The Dominator who was saved from human experimentation by Cisco, Felicity, and Nate is grateful, but not enough to want to spare the metahumans on Earth.
Arc Villain: Of the Invasion! crossover.
Contrasting Sequel Antagonist: They are a full species rather than a villain who operated alone at the time. The Dominators are hardly interested in any star-crossed couple, but on metahumans, especially Barry. Another difference is that Vandal Savage was a human mutant while the Dominators are aliens.
Even Evil Has Loved Ones: The adult Dominator that attacks the Legends in the 1980s is only there to rescue her child. Once the Legends rescue the baby Dominator from the human government agents that have captured it and reunite it with its mother, she is grateful to them and immediately leaves Earth without causing any further trouble.
Exposed Extraterrestrials: Unlike in the comics where they wore robes, here they are nude, in part because CGI of flowing robes would be difficult.
Fantastic Racism: Having seen meta-people run rampant on other worlds, they've made it their mission to purge other planets of them ASAP.
Little Green Men: Their minions, though the Dominion leaders share that trope.
Mind-Control Device: Their devices are capable of controlling anyone, including Supergirl.
More Teeth than the Osmond Family: The Dominator leaders' mouths are filled with absurdly long, dagger-like teeth.
Mythology Gag: The other name of their homeworld, Swan Moon, is a reference to the artists of their comic debut, Curt Swan and Jim Mooney.
Names to Run Away from Really Fast: The Dominators. Lampshaded by Wally:
Wally: Okay, that is not the name of a species that comes in peace.
Obviously Evil: Between their appearance and their name, it's pretty obvious that they fit the stereotype of evil, invader aliens. However, it's also played with in that they're Well Intentioned Extremists who genuinely believe they're doing the heroic thing for the universe.
Out Of Context Villain: Aliens are something completely out of Barry and Team Flash's expertise (or for Earth-1 in general), leading Barry to consult Kara, who is a friendly alien.
Scary Dogmatic Aliens: Their dogma being "any potential threat to our world has to be eliminated".
Slavery Is a Special Kind of Evil: Their Earth-38 counterparts had no qualms buying slaves, so it's likely the Earth-1 Dominators do, too.
Well-Intentioned Extremist: Their ultimate goal is to deal with perceived threats to their world, including Metahumans (which they've seen happen to other words) after Barry created Flashpoint. That includes killing millions if needed.

The Commander

Species: Unidentified alien

Portrayed By: Faran Tahir

First Appearance: "Pilot" (Supergirl 1x1)

Appearances: Supergirl

An alien military expert leading the forces aligned against Supergirl.

Bald of Evil: Has no hair.
Celebrity Paradox: 24 was mentioned by Winn in Season Two. His actor played the Starter Villain of the series' fourth season.
Dropped After the Pilot: Seemingly, since he has not been seen or heard of since.
Even Evil Has Standards: Is vocally uncomfortable when Astra announces her intentions to kill her own niece.
Human Alien: Like Kryptonians and many of his forces, though his race is yet unknown.
The Man Behind the Man: He's Vartox's superior.
No Name Given: As of the pilot, he's just referred to by his title.
The Unfought: Mainly because he's Dropped After the Pilot.
What Happened to the Mouse?: Has not been seen since The Stinger of the pilot.

Vartox

Species: Valeronian

Portrayed By: Owain Yeoman

First Appearance: "Pilot" (Supergirl 1x1)

Appearances: Supergirl

An alien convict who fights Supergirl to test her strength.

Adaptational Hairstyle Change: This version of Vartox doesn't have hair, unlike his comic books counterpart.
Adaptational Ugliness: Downplayed, but comics-Vartox look no different from a normal human despite being an alien, whereas the show's version has ridges on his head that make it clear he's not human.
Adaptational Villainy: His namesake is a superhero and friend of Superman in the comics.
Adaptational Wimp: While still strong enough to go toe-to-toe with Kryptonians, he lacks most of the powers of his comics counterpart such as Psychic Powers, Flight and energy manipulation.
Atomic Superpower? Not him, but his axe is powered by a self-generating atomic charge. Supergirl takes advantage of its explosive properties to defeat him.
Bald of Evil: He doesn't have head hair and is the Starter Villain.
Beard of Evil: He has no head hair, but he has a small beard and is a violent thug who works for Astra.
Better to Die than Be Killed: After being defeated by Kara, Vartox chooses to stab himself to death with a shard of his axe rather than be imprisoned by the DEO.
Blood Knight: He's a brutal warrior who's always eager for a good fight and even expresses an interest in battling Superman.
Brutish Character, Brutish Weapon: He's a member of a warrior race who wields a super-heated alien axe that can cut Kara's skin.
Choke Holds: His first fight with Supergirl ends with him slamming the superheroine down and choking her with both hands. The only reason he doesn't strangle her to death on the spot is because the DEO shows up in time to stop him.
Composite Character: Descriptions of the character are similar to early descriptions for another character named the Lumberjack (a one-shot Wonder Woman villain), suggesting that the two were combined into a single character or that Lumberjack was just an early codename for Vartox. He doesn't much resemble Comics!Vartox, who is a full-on homage to Sean Connery as he appeared in Zardoz.
Cowardice Callout: He accuses Supergirl of being a coward and dares her to prove him wrong by coming to fight him at the power plant.
Vartox: How many innocent people are going to die until you prove that you are not a coward?
Death by Adaptation: Vartox is still living and kicking in the comics, whereas his Arrowverse counterpart dies at the end of his sole episode by stabbing himself in the heart.
Did You Actually Believe...?: During their fight ar the power plant, Vartox mocks Supergirl for believing that she'd be strong enough to defeat him or the rest of the Fort Rozz inmates.
Vartox: You actually think that you could stop me? That you'd be able to stop any of us?
Driven to Suicide: Prefers death over incarceration.
Eye Scream: His right eye gets damaged after he's hit by the explosion of his axe.
Hoist by His Own Petard: Supergirl ultimately manages to defeat him by causing his nuclear axe to explode in his hands.
In a Single Bound: He cannot fly, but he can jump over very long distances.
Institutional Apparel: In a flashback, Vartox is shown wearing a gray prison outfit when he escaped from Fort Rozz. He's notably the only Fort Rozz prisoner ever seen wearing this kind of outfit.
Kneel Before Zod: He claims that women bow to men on his planet, and he expects Kara to do the same to him.
Lizard Folk: Winslow describes him as this, though his only reptilian features are the ridges on his skull.
Mythology Gag: At one point, Vartox contacts Kara by broadcasting on a frequency outside of human hearing, just like Lex Luthor did in Superman: The Movie.
Overclocking Attack: Kara defeats him by using her heat vision on his already super-heated axe, causing it to explode.
Politically Incorrect Villain: Tells Kara that, on his planet, women are supposed to bow before men. Presumably, another reason he killed himself is because he doesn't want to live with the shame of being beaten by a female.
Proud Warrior Race Guy: Says it would be an honor to fight Superman, and later kills himself rather than be captured. The General says this is typical of his race.
Punch Catch: At the start of their second fight, Supergirl manages to hit Vartox several times until he catches her fist and punches her away.
Revenge by Proxy: Vartox is the first of the many Fort Rozz who try to kill Kara in revenge for having been sent to prison by her mother Alura Zor-El.
Rubber-Forehead Alien: Looks human except for ridges on his head, which he hides with a hat. Blends in as a trucker.
Starter Villain: He is Kara's very first major antagonist.
Super-Strength: Enough to challenge a Kryptonian.
Villains Out Shopping: The first time we see Vartox, he's just sitting at a diner ordering coffee, and then leaves without hurting anyone.
Villain Respect: He seems to have a high opinion of Superman and considers that fighting against him would be a great honor, unlike his cousin.
Why Don't You Just Shoot Him?: Despite wielding a special axe that could easily kill Kara, Vartox abstains from using it as much as possible, instead preferring to just hit her with the handle.
Would Hit a Girl: He is absolutely brutal with Supergirl during both of their fights.
You Remind Me of X: When he first meets Kara, he tells her that she looks a lot like her mother Alura Zor-El.

Species: Hellgramite

Portrayed By: Justice Leak

First Appearance: "Stronger Together" (Supergirl 1x2)

Appearances: Supergirl

Another alien prisoner who escaped Fort Rozz after it crashed on Earth.

Adaptational Attractiveness: Hellgramite in the comics is much more obviously insectoid, with bug eyes, green skin and antennae. Here, the Hellgramites can camouflage themselves better, revealing part of their true form when they open their real mouths.
Adaptation Deviation: In the comics, "Hellgrammite" is the the surpervillain name of Roderick Rose, an enemy of Superman. In the Arrowverse, it's the name of an alien species.
Adaptation Species Change: The Hellgrammite in the comics is a human turned mutant named Roderick Rose. Here, it's an alien race.
Bad Guys Do the Dirty Work: He is the one who ends up killing Mercy and Otis Graves at the end of "Ahimsa".
Bizarre Alien Biology: Hellgrammites consume DDT as their primary form of sustenance.
Glasgow Grin: Played with; the "scars" on its cheeks actually open up to reveal its Nested Mouth.
Groin Attack: He gets hit in the groin by Alex during their fight at the end of "Stronger Together". She even Lampshades that this is a common weakness for most species.
Hoist by His Own Petard: Stabbed with his own spike.
Human Alien: Subverted; the Hellgrammite camouflages itself to look humanoid on the outside but is really an Insectoid Alien.
Irony: The DDT it feeds upon was once commonly used as a pesticide for killing Earth insects.
I Work Alone: He initially tells the Kryptonians that he doesn't want to work with them, and only changes his mind when they make it clear that they aren't giving him a choice this time.
Hellgrammite: Tell [General Astra] I prefer to go it alone.
Mook Carryover: In Season 1, the Hellgrammite is forcibly recruited as a minion by General Astra. When he returns in Season 4, he is brainwashed into serving the Children of Liberty.
The Nose Knows: The Hellgrammites have a highly developed sense of smell, allowing him to sense DDT over long distances.
Nothing Personal: He says this to Alex as he prepares to kill her at the end of "Stronger Together".
Hellgrammite: It's nothing personal. Just every species has a will to survive.
Race-Name Basis: No name given otherwise.
Rogues' Gallery Transplant: He is based on the supervillain Roderick Rose A.K.A. Hellgrammite from the comics, who is an enemy of Superman.
Silicon-Based Life: After analyzing his blood, the DEO discovers that his DNA is not carbon-based, but has a chlorine foundation.
Spike Shooter: Has the ability to shoot spikes from its palms with enough strength to pierce metal.
Unexplained Recovery: He was seemingly killed at the end of "Stronger Together" when Alex stabs him in the chest with his own spike. However, he is mentioned as being alive in the DEO prison during an episode of Season 3, and he eventually makes a full-fledged return in the Season 4 episode "Ahimsa"
Use Their Own Weapon Against Them: Is victim of this in both of his appearances.
- Alex impales him on one of his own spikes at the end of his first episode.
- A more minor example in his second appearance. He picks up two mallets to fight Supergirl, but she grabs one and throws it back at him.

Unnamed Alien Prisoner

Species: Unidentified alien

First Appearance: "Livewire" (Supergirl 1x5)

Appearances: 'Supergirl

An alien prisoner who breaks loose while being taken to the D.E.O. base and has to be subdued by Supergirl.

Annoying Arrows: A D.E.O. agent shoots a dart at her chest during her escape attempt, but she barely treats it as an inconvenience and pulls it out without any issue.
Beastess: She's a scaly alien who is very large and muscular, so much so that Kara (and the audience) believed her to be a male at first. Kara even calls her a "big, havoc-wreaking, lady-beast thing".
Breaking the Bonds: As she's taken to the D.E.O. base, she manages to break her bonds with her bare hands and tries to escape.
Defiant Captive: After being arrested by the D.E.O., she is brought to the base to be imprisoned but she manages to break free and starts beating up the agents around her before being finally subdued by Supergirl.
Female Monster Surprise: Supergirl initially assumes she is a male due to her masculine appearance, but J'onn reveals that she is actually a female.
Immune to Bullets: When a D.E.O. agent tries to shoot her to stop her escaping, she hardly seems to feel anything.
Killer Bear Hug: She tries to do this to Supergirl during their fight. It doesn't really work.
No Name Given: Her name is not known, nor is that of her species.
No-Sell: When she breaks free, a D.E.O. agent fires a stun dart at her. She doesn't even react and promptly pulls the dart out, much to the agent's confusion.
Rubber-Forehead Alien: She has scales and claws, but overall she mostly looks like a fairly tall human being.
Super-Strength: She's strong enough to break out of her bonds without much trouble, send D.E.O. agents flying with her blows and even hold her own against Supergirl herself.
The Voiceless: She grunts a lot, but she doesn't say anything resembling actual words.

Jemm

Species: Saturnian

Portrayed By: Charles Halford

First Appearance: "Human For a Day" (Supergirl 1x7)

Appearances: Supergirl

A psychic alien criminal from Fort Rozz.

Adaptation Relationship Overhaul: From a close ally of J'onn J'onzz in the comics to a hated enemy in the show.
Adaptational Villainy: In the comics, he is an ally of J'onn J'onzz, the Martian Manhunter. Granted, he was once a member of the Injustice Gang, albeit brainwashed.
And Your Little Dog, Too!: During his rant to J'onn from his cell, Jemm threatens to kill all the people he loves. However, J'onn sadly points out that most of them are already dead.
Jemm: I will grind your loved ones to dust!
J'onn: There are none left to grind.
Attack Its Weak Point: During their final confrontation, Alex manages to shoot Jemm's crystal out of his forehead. It's not enough to defeat him, but it makes him unable to fire energy beams.
Bait-and-Switch Comment: A minor example, but when "Hank Henshaw" comes to inspect his cell, Jemm threatens to "expose his true identity", giving the impression that he knows he's secretly a Green Martian... only to then clarify that he meant "as a coward".
Brought Down to Badass: Alex manages to destroy his crystal, but even without it he is too powerful and would have killed her without J'onn's intervention.
Composite Character: The powers and origin are Jemm, but the personality, appearance, and rivalry with Martian Manhunter are closer to Despero minus his head fin.
Defiant Captive: During his imprisonment at the DEO base, Jemm keeps using his energy blasts to try to break through his cell, and makes an escape at the first opportunity. J'onn even refers to him as an "unruly guest".
The Dreaded: Even Alura considers Jemm one of the worst criminals she ever imprisoned in the Phantom Zone. When he manages to escape from his cell, the Alura hologram tells the DEO agents that they are in serious trouble and need Kara's help to have a chance to survive.
Evil Sounds Deep: And is very fond of cruel, melodramatic speeches.
Head Blast: Jemm can fire energy blasts from the crystal on his forehead.
Immune to Bullets: Gets shot with full-auto from a rifle, multiple shotgun rounds, and Guns Akimbo from Alex's pistol, none of which hurt him.
My Name Is Inigo Montoya: Apparently, he's been bringing up his name and titles over and over ever since his arrest in an effort to intimidate the DEO agents, to the point that J'onn is getting tired of hearing it.
Jemm: I am Jemm! Master of the Faceless Hunters! Conqueror of...
J'onn: Twelve worlds. Yeah, I heard you the first 10 times. It's not getting any more impressive.
Neck Snap: He's taken out by one courtesy of J'onn J'onzz.
Offstage Villainy: Jemm claims to have conquered twelve planets and the Alura hologram describes him as a particularly ruthless individual, but we don't actually get to see any of the crimes that got him imprisoned in the Phantom Zone and later at the DEO base.
Perpetual Frowner: He is always seen with an angry scowl on his face.
Pointy Ears: His ears are slightly pointed.
Power Crystal: The gem on his forehead allows him to shoot beams. Shooting it out, as Alex does, pisses him off more than actually hurts him.
Psychic Powers: Telepathy and mind control.
Super-Strength: He has greater than human strength, at least enough to lay out Alex with one swing.
Tailor-Made Prison: As J'onn explains, Jemm's cell in the DEO base has neural shielding that prevents him from using his telepathic powers.
Whoosh in Front of the Camera: He does this quite a few times when he ambushes the three DEO agents sent after him.
Would Hit a Girl: He smacks Alex around and tries to kill her during their final confrontation.

Unnamed Psychic Alien

Species: Unidentified alien

Portrayed By: Ric Sarabia

First Appearance: "Blood Bonds" (Supergirl 1x9)

A ten-eyed alien with psychic powers who works as an interrogator for Non.

Bald of Evil: He doesn't have a single hair on his head and serves as a henchman for Non.
Black Eyes of Evil: All ten of his eyes are black, and he's part of the Fort Rozz Alliance.
Canon Foreigner: He doesn't seem to be based on any character in the comics.
Chrome Dome Psi: He's a telepathic alien with a bald head.
Evil Minion: He works for Non as an interrogator for the prisoners, but doesn't get involved in combat.
Extra Eyes: He has two eyes in the right place and eight additional smaller eyes all over his forehead, similar to a spider.
Neck Snap: Non kills him by breaking his neck with one hand.
Non-Action Guy: He doesn't seem to have any fighting skills whatsoever, considering he didn't participate in the assault on the Lord Technologies building and doesn't even try to defend himself when Non kills him.
No Name Given: Neither his name nor that of his species is revealed.
Psychic Powers: He's a member of an alien race famous for its telepathic abilities, though he's not powerful enough to read the mind of the Green Martian J'onn J'onzz.
Psychotic Smirk: He has a sadistic little grin on his face when Non threatens a captured J'onn J'onzz to snap his neck.
Rubber-Forehead Alien: He could almost pass off as a normal human if it weren't for those eight black eyes on his forehead.
Squishy Wizard: He's apparently a powerful telepath, but he's so physically weak that Non is able to kill him with a slight touch.
Wrong Assumption: When he fails to probe the mind of a captured "Hank Henshaw", he assumes that humans must have developed some kind of psychic-blocking technology, not realizing that "Hank Henshaw" is actually the Green Martian J'onn J'onzz and is using his own Psychic Powers to protect himself.
You Have Failed Me: Non is not happy to learn that he's unable to scan J'onn's mind and snaps his neck as punishment.
We Hardly Knew Ye: Only appears during one scene before Non breaks his neck.

Portrayed By: Blake Berris

First Appearance: "Truth, Justice, and the American Way" (Supergirl 1x14)

A former alien convict imprisoned on Fort Rozz marked as "Prisoner #2444. He is found and killed by the Master Jailer.

Asshole Victim: He's said to be guilty of committing armed theft and murdering people to feed on their rotten flesh, so he receives little sympathy from the audience when he gets executed by Master Jailer.
Canon Foreigner: There is no character called "Gabriel Phillips" in the comics.
Facial Markings: In his true form, he has several vertical lines on his face, though this could simply be an attribute of his species.
Face of an Angel, Mind of a Demon: During the briefing, J'onn describes him as someone who looks pretty good but is actually extremely dangerous.
J'onn: Don't be fooled by the pretty face. This thing is nasty.
Human Disguise: After Fort Rozz crashed on Earth, he used his Shapeshifting powers to masquerade as a human named "Gabriel Phillips". However, the Master Jailer is still able to find him and points out that his disguise isn't enough to fool him before executing him.
Master Jailer: Disguising yourself in human skin will not keep you from facing justice.
I'm a Humanitarian: According to J'onn, he tends to kill people to feed on their rotten flesh. Thankfully, we don't actually see him do that.
Informed Ability: J'onn warns the DEO agents to be careful when apprehending him because he's a particularly vicious and dangerous foe with a harmful bite. However, none of this is shown during his short screen time, as he gets captured without any trouble by the Master Jailer and overall comes across as a pitiable victim.
No Name Given: He was masquerading as a human named "Gabriel Phillips", but his real name is unknown. And neither is the name of his species for that matter.
Offstage Villainy: We don't actually see him doing anything evil on-screen, but he's said to have committed armed robberies, murders, and to have eaten some people's rotten flesh in the past.
Off with His Head!: He ends up being decapitated by the guillotine of the Master Jailer.
Rubber-Forehead Alien: In his true appearance, he doesn't look that different from a normal human aside from his skin color, his eyes and his Facial Markings.
Sacrificial Lamb: His only role is to be guillotined by the Master Jailer in an early scene to show what happens to his victims.
Scream Discretion Shot: We don't get to see his head being chopped off, but we do see the guillotine coming down as he's screaming in terror.
Shapeshifter: He can modify his appearance by vibrating his body to make himself look like a normal human.
Villains Want Mercy: He asks the DEO agents for help when he's about to be captured by the Master Jailer at the warehouse, and later he tries to convince Master Jailer to let him go rather than execute him.
We Hardly Knew Ye: He only appears in two scenes before getting killed by the Master Jailer.
You Are Number 6: He was Fort Rozz "Prisoner #2444".

Kara: "Water".
Luzano: Yes, of course. "Water".
Cool Teacher: Currently works as a college professor.
Exotic Extended Marriage: He casually mentions to Supergirl that he had several wives on his planet before his imprisonment.
Face Death with Dignity: Zig-Zagged. He does admit that he's afraid of dying when he's about to be executed by the Master Jailer, but he still puts a brave face and tries to plead for Kara to be spared rather than beg for his own life.
Going Native: He now considers himself an Earthling after living there for so long.
Human Aliens: His human looks would contradict other Starhavenites that would later appear in the series (though said Starhavenites are from the Valerian tribe).
Interspecies Romance: He's Happily Married to a human woman.
Justified Criminal: The only reason he became a drug smuggler is because he needed money to pay for the care of his sick wife.

Unnamed K'hund

Species: K'hund

Portrayed By: Gary Kasper

First Appearance: "Falling" (Supergirl 1x16)

Appearances: Supergirl

An alien criminal who escaped Fort Rozz and went on a gold robbery spree.

Adaptational Ugliness: He is much less human-looking than the Khunds from the comics.
Adaptation Name Change: A minor example, but his alien species is known as "Khund" without apostrophe in the comics.
Bank Robbery: He has robbed two armored trucks carrying money and is in the middle of robbing a third one when the DEO shows up to arrest him.
Barrier-Busting Blow: During his attack on the armored truck, he punches through the back door to hit one of the security guards behind.
The Cameo: He makes a brief appearance among the alien prisoners of the DEO who are eagerly waiting to be released by the brainwashed Lucy Lane in "Myriad".
Cassandra Truth: The K'hund claims Supergirl didn't even bother trying to capture him, only to be incarcerated by the DEO for his troubles.
Curb-Stomp Battle: He tries to go against a Red Kryptonite-influenced Supergirl, only to get his ass handed to him in less than 30 seconds, without even landing a single blow on her.
Electronic Eyes: The K'hund has a cybernetic eye in place of his left eye to enhance his vision.
Evil Wears Black: In both of his appearances, he is wearing a black jacket.
Immune to Bullets: One of the security guards fires several bullets at him during his attack on the armored truck, but it has little to no effect on him.
In a Single Bound: He is able to jump pretty long distances, as shown when a team of DEO agents surround him and he escapes from them by jumping to another alley.
Informed Ability: J'onn describes him as a particularly strong opponent, even compared to the other Fort Rozz Escapees. However, he gets overpowered with ridiculous ease by a Red Kryptonite-influenced Kara, who wasnt even taking the fight seriously, and he ends up being captured offscreen by Alex, of all people.
Not Worth Killing: After effortlessly defeating the K'hund, the Red Kryptonite-influenced Supergirl doesn't bother arresting him and allows him to leave just because she believes that he isn't worth her time.
"Open!" Says Me: When he attacks the armored truck, the K'hund thrusts his arm through the back door and forcefully rips it off.
Punch Catch: He tries to throw a series of punches at Kara during their fight, only for her to easily catch his fist and twist his wrist.
Punctuation Shaker: He's a member of an alien species that has an apostrophe in the name.
Put on a Prison Bus: He gets arrested by Alex not even halfway through the episode "Failling" and is taken to the DEO desert base. He is later shown to still be imprisoned there in the episode "Myriad".
Race-Name Basis: He only gets called "K'hund" by the other characters. For his part, he also refers to Alex Danvers as "Human" at one point.
Rogues' Gallery Transplant: Played With: In the comics, the Khunds were introduced as enemies of the Legion of Superheroes, though they went one to face many other DC heroes afterwards, including Supergirl.
Small Role, Big Impact: He's a minor villain who only appears in two or three scenes, but the video of Supergirl letting him escape is the reason Siobhan Smythe gets fired from CatCo and ends up on the path of supervillainy.
Super-Strength: He is strong enough to lift an armored truck and rip off its door without much effort, as well as punch through cinderblocks with his bare hands. J'onn even says he's stronger than most Fort Rozz prisoners.
That Liar Lies: When J'onn mentions that Supergirl told them that he got away from her after their fight, the K'hund angrily says that she was lying and that she actually let him go.
K'hund: She's a liar! She said she didn't want to waste her time with me.
Villain Reveals the Secret: After defeating him, the Red Kryptonite-influenced Supergirl allows the K'hund to leave and claims to the DEO that he managed to escape her. However, the K'hund is later arrested by Alex and reveals to her and J'onn what Supergirl did, making them realize that there is something wrong with her.
Would Hit a Girl: He is quite eager to fight Supergirl since her mother had sentenced him to be imprisoned on Fort Rozz.

Appearance: Supergirl

An alien criminal who became an art fence after escaping Fort Rozz.

Briefcase Full of Money: He has one of his henchmen bring a case filled with money for the deal with the painting of Van Gogh.
Choke Holds: Right after escaping from his cell in "In Search of Lost Time", he immediately starts strangling some guards to death with his bare hands.
Is This a Joke?: Asks this after examining the painting given to him by Lyra and realizing that it's not the real one.
Mandrax: Is this a joke? This is a fake!
Looks Like Orlok: Pretty much Count Orlok with two vertical forehead ridges.
No-Sell: When Guardian shows up and tries to give him a strong Shield Bash, Mandrax barely reacts, much to James' surprise.
Guardian: That usually works...
Not Worth Killing: He considers humans to be so weak that killing them is beneath him. When Winn tries to stand up to him to protect Lyra, he scoffs at the idea of fighting such a weak being. That said, he is willing to make an exception for Guardian, as he feels that he fought well enough.
Mandrax: [To Winn] I don't deal with human criminals. You break too easily.
Paper Destruction of Anger: When he finds out that the Van Gogh painting Lyra brought him is a fake, he angrily tears it up.
Puny Earthlings: He has a very low opinion of humans, viewing them as weak.
Put on a Prison Bus: He is handcuffed and taken into custody by Alex at the end of "Star-Crossed", and is shown to still be imprisoned in the DEO headquarter by the time of Season 3. He briefly manages to escape from his cell during "In Search of Lost Time", but he gets recaptured before going very far.
Super Mob Boss: He is a super-strong alien who serves as the boss of a dangerous gang of art dealers.
Super-Strength: He is far stronger than any normal human being, throwing Guardian around like a ragdoll during their fight. After his escape from the DEO prison in Season 3, he manages to give Mon-El some trouble, and seems confident enough to take on Supergirl herself.
Villain Respect: Despite his usual disdain for humans, he admits that Guardian put up a good fight after defeating him.
Mandrax: Congratulation, you fared better than most. You can at least take that to your grave.
Would Hit a Girl: He is more than willing to hurt women, as seen when he threatens to kill Lyra in "Star-Crossed". He also tries to attack Kara from behind in "In Search of Lost Time".

Wild Card: She spends the season at various points either helping or hindering the heroes depending on the exact situation at hand, though ends the season firmly on the side of good after seeing the way Mick and the rest of the Legends are caring for her offspring.

Mick and Kayla's children

Half-Human Hybrid: They were birthed from the a combination of Kayla's Necrian DNA and Mick's human DNA.
Ridiculously Cute Critter: They may look like monstrous aliens, but that doesn't change how cute they are.

Bishop's Samples

Giant Air Feeder

Species: Giant Air Feeder

First Appearance: "Meat The Legends" (Legends of Tomorrow 6x02)

Appearances: Legends of Tomorrow

One of the aliens collected by Kayla for Bishop's experiments. It ends up in California in 1955.

Meaningful Name: It's giant, it flies, and it has a double meaning with the feeder part: not only does it feed on people but it feeds people, albeit only thanks to the help of a desperate burger joint.
Monster Organ Trafficking: The slime from its chrysalis is harvested for a burger joint's secret sauce, which lasts until it hatches and eats the person doing the mainlining.
Non-Malicious Monster: It's aggressive and eats people, but all appearances point to it being a wild animal rather than a malevolent being.

Lord Knoxicrillion

Species: Archai

First Appearance: "The Ex-Factor" (Legends of Tomorrow 6x03)

Appearances: Legends of Tomorrow

One of the aliens collected by Kayla for Bishop's experiments. He ends up in 2045, where he seeks to challenge Earth's ruler to a death duel.

Defeat Means Friendship: After losing a singing competition to Zari he swears loyalty to her. Shame Rory didn't watch where he stepped.
Invincible Villain: His technology is superior, easily overpowering the Legends' attempts to restrain him and capable of withstanding a nuclear assault. And should all that fail, he has an invasion armada to call upon if his challenge isn't met. The Legends' only option is to meet his terms and try to defeat him in a fair challenge.
Mobile-Suit Human: His true form is a tiny alien smaller than a soda can.
Mundane Utility: Uses his hyperadvanced technology to synthesize a perfect singing voice from thousands of human performers and compete in a singing competition.
Non-Human Non-Binary: Referred to by he/him pronouns, but mentions that his species doesn't use a human binary and all bear children.
Skeletons in the Coat Closet: He wears a necklace of assorted bones, presumably trophies from past conquests.

Other Aliens

Despero

"Bear witness to a coming Armageddon that you create 10 years from now, one that destroys your own planet. It's already happened Flash, that's why I, Despero, have to kill you. It's how I save our world."

Species: Kalanorian

Portrayed By: Tony Curran

First Appearance: "Armageddon Part 1" (The Flash 8x1)

Appearances: The Flash

An alien from the future who seeks to kill The Flash to prevent an Armageddon that he believes the Flash will cause.

Achilles' Heel: He draws his power from the Flame of Py'tar. Chester manages to build a pair of boots that can absorb energy, allowing Barry to kick the Flame out and render Despero vulnerable.
Adaptational Modesty: He is usually a Walking Shirtless Scene with only pants and a cape for clothing. Here he has a more standard attire that covers his torso.
Adaptational Nice Guy: Comics Despero was a thorough monster. In this show, it seems at first as if Despero had Adaptational Heroism going for him, being willing to give innocents and other heroes a chance to flee from his rampage against Flash and telling the story about how he was a rebel against a dictator on his planet. Later it's revealed he was Evil All Along and that he was willing to destroy Central City just to stop Armageddon. In spite of this, he's still better than his comics self, being more of a misguided Well-Intentioned Extremist than a power-hungry mass murderer.
Bad Future: He comes from one and goes back in time to prevent it from occurring.
Big Bad: Of the Armageddon arc of Season 8 of The Flash. Later turns into a Big Bad Ensemble with Eobard Thawne, who manipulates the timestream to become the Flash and gaslights Barry.
Celebrity Paradox:
- Doctor Who has been referenced quite a few times in the Arrowverse. Tony Curran played Vincent van Gogh on that show, which was one of his Star Making Roles.
- The Marvel Cinematic Universe has been alluded to in the Arrowverse. His actor was on both Thor: The Dark World and Daredevil as separate characters.
Composite Character: Comics Despero had no relation to the Armageddon arc. Here he takes the place of Waverider^note as the time traveler trying to prevent a dystopic future from a superhero who turns evil. Later it's revealed, he also takes the place of Monarch, a tyrant who oppressed the Earth in the future.
Evil All Along: He is the tyrant he was talking about in his backstory, and intends to take over the Earth once Armageddon is prevented.
Evil Is Bigger: In his natural form he towers over the humans, being a similar height to Thanos.
Faux Affably Evil: Despite being an Adaptational Nice Guy who's at least a somewhat better person than his comic book counterpart and other media portrayals of his character, Despero is implied to be this at the end of the day. He has moments where he gives Flash's allies and civilians a chance to leave the scene, coming across as a Noble Demon. But in the third act of Armageddon, he casually uses his telepathy to make a bunch of radiation workers just doing their jobs fight each other to the death, with the heavy implication that his public displays of magnamity in front of an audience could very well have been just an act. And then there's the fact that he's ultimately revealed to be the dictator of his homeworld that he lied about rebelling against.
A Form You Are Comfortable With: Most likely the reason why he takes a human form on Earth.
Immigrant Patriotism: After being banished from his own world, he took on Earth as his adopted new home world. Stopping the destruction of it is his main motivation.
Invincible Villain: He is described as having power on par with a Kryptonian and No Sells everything Barry throws at him. The heroes have no way of defeating him and instead have to convince him to stop. In Part 5 of "Armageddon", they finally come up with a method to defeat him, taking this title away from him.
Knight Templar: He wishes to kill the Flash to prevent him from ending the world. Though he does give Barry a chance to change his fate.
Mind Rape: He can subject his victims to traumatizing psychic hallucinations which he typically uses for interrogation. The most severe one is given to Team Flash where he tries to dilvuge the location of the Flash and upon giving no answer it results in all of their deaths.
No-Sell: The Flash and Atom's most powerful attacks don't even phase him. It takes Atom scrambling Despero's own teleporter to momentarily send him away and even that's a temporary solution. Once Team Flash figures out a way to negate the Flame of Py'tar, he loses this invulnerability.
Pragmatic Villainy: When the truth of his backstory is revealed, it becomes apparent that he doesn't want to save Earth for its own sake, but because if the Earth is ruined he won't have anything to rule over.
Third Eye: Sports one in his natural form that he can use to channel his psionic powers like reading minds or projecting illusions.
Well-Intentioned Extremist: He believes the Flash is responsible for an apocalypse and seeks to kill him before he turns villainous, and has little problem with killing Team Flash, too, if they get in the way. His ruthlessness stems from his backstory, in which he overthrew the dictator of his world but let him live, which proved to be a mistake. Later this gets muddied with the reveal Despero himself was the dictator, but his intentions to save the world still seem to be true.

Thanagarians

Appearances: Legends of Tomorrow

An alien species that will conquer Earth in the very distant future.

Aborted Arc: They were never mentioned again after Season 1. And after multiple changes to the timeline, the Crisis itself, and Legends of Tomorrow ultimately coming to an end, it's unclear if they'll ever come into play again.
Alien Invasion: They are seemingly fated to conquer Earth, which is why the Time Masters manipulated events to put Vandal Savage in charge. They believe a united Earth, even under Savage, is the only way to stop them.
The Ghost: Their earth-1 versions only made an appearance via holographic recordings.
Greater-Scope Villain: To Season One of Legends of Tomorrow, as they provided Vandal Savage with his powers to begin with (along with Hawkman and Hawkgirl) and are also the reason the Time Masters helped him rise to power, but do not actually make an appearance in the season.
Unobtainium: They are renowned for their Nth Metal, regarded as the highest quality metal in the universe.
Precursors: They were the ones responsible for the meteor shower in Ancient Egypt that granted Vandal Savage immortality and Kendra and Carter their powers.
Winged Humanoid: Kind of their trademark, as their Nth metal creates these.

Master Jailer

Carl Draper, aka Master Jailer

"What I have done is protect this city. This world. Humans understand little about justice. Justice must be absolute. I'd hoped that you'd see justice the same way your mother did. The way I do."

Species: Trombusan

Known Aliases: Master Jailer, Carl Draper

Portrayed By: Jeff Branson

First Appearance: "Truth, Justice, and the American Way" (Supergirl 1x14)

Appearances: Supergirl

An alien who was a third-generation prison guard at Fort Rozz until the prison ship landed on Earth, where he became a vigilante and went after Fort Rozz escapees. On Earth, he poses as Detective Draper of the National City Police Department.

Adaptational Species Change: He's a human in the comics. Here, he's an alien.
All Crimes Are Equal: He executes the escapees regardless of their crimes, and ignores the fact that they were living peacefully on Earth until he started hunting them.
Arm Cannon: The Master Jailer armor can fire blue-white energy blasts from its forearms.
Badass Boast: Says a pretty cool one just before executing his targets.
Master Jailer: No one escapes the Master Jailer!
The Bad Guys Are Cops: As it turns out, the police detective who was questioned by J'onn and Alex about the recent series of alien murders.was actually the killer all along.
Bitch in Sheep's Clothing: He pretends to be a reasonable cop to Alex and Hank.
Black-and-White Insanity: If you break the law in any way, you forfeit your right to exist. This provides a handy lesson for Kara when she's starting down the same thought process at the time he shows up.
Collapsible Helmet: He can retract the helmet of his Master Jailer armor at will, as shown when a captured Supergirl urges him to show his face.
Cop Killer: He shoots his partner, Detective Jim Warren, right after revealing himself as the Master Jailer to Supergirl.
The Dreaded: The Fort Rozz escapees are terrified of him and for good reason, to the point that one of them would rather ask for help from the DEO agents who came to arrest him than fall into his hands.
Fair Cop: He disguises himself as a cop.
Flying Firepower: His armor allows him to fly and to shoot energy blasts, though he never uses both of these abilities at the same time. In fact, he's never seen flying again after his first scene.
Heavily Armored Mook: He wears a very bulky armor.
Henshin Hero: Yes and no. He can summon his whole armor seemingly at will, without even the need to say a catchy command phrase. He himself is pretty much the only one who'd call him a hero, though.
Human Alien: Without his armor, he looks so much like a human that he managed to pass himself off as a normal police detective for some time.
Hypocrite: He seeks to execute all criminals, but he kills various DEO members and an innocent police officer, and tries to kill Alex and Supergirl.
Immune to Bullets: The DEO agents' bullets bounce off his armor without doing any damage.
Instant Armor: When he's posing as "Detective Draper", he can instantly make his armor appear around him out of nowhere.
In the Blood: His father and grandfather were also prison guards. J'onn even Lampshades it.
Alex: His father was a guard. And his grandfather before him.
J'onn: This job is in his blood.
"It" Is Dehumanizing: A variant. He always addresses the Fort Rozz criminals by their prisoner number, showing his contempt for them.
Judge, Jury, and Executioner: His modus operandi.
Knight Templar: He will stop at nothing to execute the Fort Rozz inmates in the name of justice.
Lawman Baton: He uses a police baton to incapacitate Alphonso Luzano. By analyzing it, the DEO realizes that the Master Jailer must be posing as a policeman.
Loophole Abuse: When the alien criminal "Gabriel Phillips" tries to protest against his execution by saying that capital punishment is not allowed on Krypton, the Master Jailer coldly points out that they're not on Krypton right now and executes him anyway.
Malevolent Masked Man: His face is always covered by a menacing helmet.
The Master: Close enough. He's a supervillain who calls himself "The Master Jailer".
Off with His Head!: He beheads the inmates he captures.
Rogues' Gallery Transplant: He's a Superman villain in the comics.
Serial-Killer Killer: He's a serial killer whose targets are escaped criminals from Fort Rozz, who tend to be murderers, thieves, or drug smugglers.
Sole Survivor: He is apparently the only guard of Fort Rozz who didn't get killed by the prisoners after the crash of the prison.
Tall, Dark, and Snarky: He stands 6'1 1/2 and definitely starts snarking after his cover was blown.
Wardens Are Evil: He was one of the wardens at the Fort Rozz prison and is merciless with the prisoners.
Would Hit a Girl: Not only does he have no qualms about fighting Kara, he also attempts to shoot and later guillotine Alex. Some of the Fort Rozz criminals he killed were women as well.

A carnivorous plant that restrains its victims with visions of their greatest desire.

Accidental Pervert: It strongly clings to Kara's chest, though without sexual malice on its part. The fact that it has tentacles also does not help.

Appearances: Supergirl

A powerful entity from an unknown planet who was imprisoned in the Phantom Zone for assisting the White Martian's genocide of the Green Martians.

Aborted Arc: In her sole appearance, she was fairly blatantly set up to appear again, but such a thing never happened and the mystery surrounding what she is gets dropped entirely.
