Species: Human

Portrayed By: Scott Michael Campbell

First Appearance: "How Does She Do It?" (Supergirl 1x4)

Appearances: Supergirl

A former employee of Lord Technologies. He was paid by Maxwell Lord to plant bombs all over National City in order to test Supergirl.

Alas, Poor Villain: Kara is upset when he dies, as she realized he wasn't really evil.
Beard of Evil: He's a Mad Bomber with a beard. Subverted, as he turns out not to be that bad of a guy.
Canon Foreigner: There are no characters named "Ethan Knox" in the comics.
Dead Man's Switch: A variation. His explosive jacket is rigged with an altimeter so that if Supergirl moves him out of the train, it goes off.
Driven to Suicide: He ends up blowing himself up after making sure Supergirl has saved the rest of the people on the train.
Even Mooks Have Loved Ones: The only reason he agreed to set up some bombs on behalf of Maxwell Lord is because he needs money to pay for the care of his sick daughter.
Forced into Evil: Ethan Knox has no desire to harm anyone, it was Maxwell Lord who made him plant bombs all over the city in exchange for paying for the care of his sick daughter.
Mad Bomber: Subverted. He is initially assumed to be this, with Kara even calling him "a literal mad bomber," but it eventually turns out that his motives are a little more complex than they appear.
Papa Wolf: He's willing to become a bomb-throwing terrorist in order to save his daughter.
Tragic Villain: Poor guy. After he got fired from his job, his wife divorced him and his daughter contracted a serious illness. Lacking the financial means to pay for her treatment, he ends up becoming a bomber for his former boss Maxwell Lord in exchange for the money he needs. However, he is deeply ashamed of what he's being forced to do and ultimately commit suicide by blowing himself up, as he feels he can no longer look his daughter in the eye anymore.

Species: Human^note

Known Aliases: Toyman I

Portrayed By: Henry Czerny

First Appearance: "Childish Things" (Supergirl 1x10)

Appearances: Supergirl

Winn's father, a genius toymaker who snapped after his designs were stolen and became obsessed with revenge at any cost.

see the Smallville: Other Major Villains page for the Earth-167 character who bears his name and background

see the Arrowverse: Other Earths page for his counterpart in an undesignated Earth

Abusive Parents: When Winn was a child he drove Winn and his wife off the road when they tried to get away from him, and he threatened to kill Winn if she ever tried to take Winn away again. By the time of the series, he tried to force Winn to kill Chester Dunholtz to ride him into villainy.
Action Dad: He is Winn's estranged father and a scary man with harmful weapons disguised as toys.
Adaptational Relationship Overhaul: In the show, Winslow mentored Jacqueline Nimball so that she could succeed him as Toyman and continue his work after his death. In the comics, Jack Nimball never met Winslow Schott before becoming a supervillain and actually assumed the identity of the second Toyman without his consent, with Winslow considering him a disgrace to the name of Toyman and eventually killing him.
Adaptational Seriousness: He is much less of a Manchild than most other versions of Toyman, and is portrayed as a very serious and threatening villain.
Adaptation Dye-Job: He's an Evil Redhead in the comics. Here, he has gray hair and his actor has brown hair in his youth.
Archnemesis Dad: He is Winn's father, and the one villain he fears and despises the most by a long margin.
Asshole Victim: His company and his toys being stolen causes less sympathy now that it was revealed that he was very abusive to his wife and he was willing to kill his own son all along.
Ax-Crazy: The FBI agent Chase describes Winslow Sr as unhinged and dangerous, which is something his son Winn doesn't deny. Considering the number of people he kills without remorse, it's fair to say he more than live up to that description.
Badass Normal: He has no powers, but he's a genius inventor who's able to pose a threat to Kara.
Beware the Quiet Ones: Winn describes him as having been a rather quiet person before he snapped and became a murderous supervillain.
Bus Crash: After last being seen being arrested by Supergirl in Season 1, Winslow Schott Sr. is revealed by a newscast to have died in prison during Season 3.
Car Fu: As Mary reveals to Winn in Season 3, she tried to take him to a domestic abuse shelter when he was 9, but Winslow found out about it and stole a car to ram them off the road, giving Winn a concussion.
Celebrity Paradox: Quantico is mentioned on Season Two. His actor plays a Recurring Character there.
Cop Killer: He kills several prison guards during his breakout. Agent Chase also mentions that he killed one of her fellow FBI agents during his apprehension.
Crazy-Prepared: The main reason he's able to be a threat to Supergirl despite being a normal human.
Deadly Gas: When the FBI raids the old toy store in "Childish Things", Winslow releases lethal gas from the stuffed animals to poison them. Fortunately, Supergirl arrives and manages to inhale all the gas before exhaling it into the sky.
Death by Adaptation: The comic version of Winslow Schott/Toyman is still alive in the comics. In the show, he dies of an unknown disease in Season 3. While an episode of season 5 treveals hat he uploaded his consciousness to the digital space, he still gets deleted by the end of the episode.
Domestic Abuse: It turns out he was abusive to his wife and forced her to stay away from Winn.
The Dreaded: Not only have Winn and his mother spent a large part of their lives terrified of him, but even the guards at his prison are disturbed by him and mention having nightmares every time they interact with him.
Dropped a Bridge on Him: For such a dangerous villain who caused so much issue to Winn, he ends up dying of a simple illness entirely off-screen during Season 3. Subverted as he eventually returns in Season 5 due to having uploaded his consciousness to the digital space, and he gets a much more significant death in helping his son defeat Toyman II.
Even Evil Has Loved Ones: Deconstructed. He calls Winn his greatest creation and is obsessed with being together with him, even if they're both in prison. He even says that he wants Winn to become even eviler than he is.
Evil Counterpart: He's this for his son Winn, who is very much aware of it and is deeply concerned about it. Both of them were brilliant engineers with a passion for toys, both of them started out as timid and reserved people with a tendency to repress their feelings, both of them did thankless jobs where they were constantly looked down upon and pushed around by their bosses. While Winslow Sr. eventually snapped and became a ruthless murderer, Winn remained a good-hearted person, but is still worried that he may end up like his father one day. Ultimately, both of them took on the identity of "Toyman", but Winslow Sr. used it to be a supervillain and Winn to be a superhero.
Evil Old Folks: Assuming he's the same age as his actor, Winslow is in his late 50s/early 60s and has graying hair, but that doesn't stop him from being a formidable villain.
Four Eyes, Zero Soul: He wears glasses with very thick lenses.
Gadgeteer Genius: He makes all of his weapons.
Heroic Sacrifice: In his last appearance, Winslow claims that he's willing to help Winn delete Toyman II, even though he knows full well that this will cause his own death. Against all odds, he actually proves he was sincere by spending his last moments holding Toyman II back so that Winn can delete them both.
I Have No Son!: Inverted. Winn was the one who (rightfully) disowned him.
Improvised Weapon: All of his weapons are modeled like toys.
Killer Yo-Yo: Uses one when he escaped.
Know When to Fold 'Em: After Supergirl manages to stop his bombs at the toy convention in "Childish Things", Winslow tries to run away, but he doesn't get far before being caught by the superheroine.
Mad Bomber: He is a psychopathic killer who has an affinity for using explosives. His first victims were killed by a bomb he hid in a teddy bear, and he also hides ten bombs at the toy convention attended by his former boss.
Murder by Mistake: According to Winn, he started his villainous career by attempting to kill his boss with a package bomb, but his secretary opened it instead and died in the explosion along with five other innocent people, whereas his boss survived.
Not His Sled: As noted with Winn, it's the inverse of the "Winslow Schott Sr./Jr." situation on Superman: The Animated Series: It's Senior who's Toyman, not Junior.
Playing Possum: In his first scene, Winslow fakes being dead in his cell so a prison guard will open the door, then he uses his Killer Yo-Yo to kill him.
Quicksand Sucks: In his first appearance, he manages to trap Supergirl in a box full of thermite-laced quicksand, intending to drown her since she still needs air. She freezes it and breaks free.
Redemption Equals Death: After surviving his initial death via Brain Uploading, he gets deleted for good when he helps Winn stop his Evil Doppelgänger Toyman.
Rogues' Gallery Transplant: He's a Superman villain in the comics, but here he is a Supergirl villain.
Sadistic Choice: In his first episode, Winslow gives one to his son. Either he kills Chester Dunholtz with a special plastic weapon, or Winslow activates the remote-controlled bombs hidden in the toy convention, killing dozens of people.
Sanity Slippage: He snapped after his company was stolen from him, and being imprisoned for almost two decades just made him worse. Except he was always evil, since he was always a domineering man.
They Look Just Like Everyone Else!: Winn said his dad was a very happy toymaker. But it turns out Winslow was always secretly angry deep down, but never said anything.
Unseen No More: Winn first mentioned his criminal father in "Livewire", but he doesn't actually appear on-screen until five episodes later in "Childish Things".
The Villain Knows Where You Live: He somehow knows where Kara lives, and waits for Winn to get out of her apartment in "Childish Things" to chloroform him and kidnap him.
You're Insane!: He calls Toyman II a "psycho" in "Back from The Future - Part 2". Coming from him, that really means something.
Winslow Sr: That's because you're a psycho!

Adaptational Wimp: Her comics counterpart was a competent fighter in her own right. Here she doesn't have any need to fight.

Celebrity Paradox: Winn explicitly mentions Doctor Who during the battle with Indigo. Her actress guest-starred on the Spin-Off Torchwood: Miracle Day.
Dragon Lady: Complete with dragon tattoos all around her body.
Fantastic Racism: Roulette's schemes are often at the cost of aliens. As aliens have no rights, she is willing to exploit them to make a quick buck.
Fight Clubbing: She's the main promoter of a string of illegal fight clubs. The latest one uses aliens for fighters. Not all of them willingly.
Foil: She and Lillian Luthor. Both have Fantastic Racism, abuse aliens in shadowy organizations and utilize Screw the Rules, I Have Connections!. However, Veronica is a society Grand Dame with no reason to hide while Lillian is an Evil Matriarch who prefers to work behind closed doors.
For the Evulz: She hosts her fight clubs not for the money, but because she enjoys the blood sport.
Fur and Loathing: Will occasionally wear a black fur coat when she goes out.
Karma Houdini:
- She's able to weasel out of trouble in her debut appearance due to having the right friends in the right places. However Alex and Maggie make it clear that they're both keeping a close eye on her activities.
- In her second appearance she's apparently left stranded on an alien planet where some buyers had been expecting to get human slaves, though nothing's made clear.

Large Ham: But only in the ring. Outside she's more soft-spoken and chilling.
Limited Wardrobe: Wears the same red Qiapo and black fur coat every night.
Loophole Abuse: At the time of the episode, aliens weren't protected by the law, which is why Sinclair escaped custody so quickly.

Off on a Technicality: It's hard to keep her incarcerated.
Race Lift: In the comics she's a white girl who wants to be a Dragon Lady and so dresses the part. Here she's of Asian descent, like she was in Smallville.

First Appearance: "The Darkest Place" (Supergirl 2x7)

Comic-Book Movies Don't Use Codenames: The show doesn't designate Phillip by his "Barrage" name from the comics.
Crusading Widower: He becomes a Vigilante Man after his wife's murder.
Expy: Basically the show's version of The Punisher.
Evil Counterpart: To Guardian, obviously. Winn even calls him James's "Evil Twin". Like James Olsen, Phillip Karnowsky is a normal human who has no power but is a good fighter, puts on armor to fight criminals in order to make the city safer, and is motivated by the death of a family member. However, the difference between the two is that Phillip is consumed by his thirst for revenge and therefore has much more brutal and ruthless methods, whereas Guardian never kills criminals.
Frame-Up: Phillip intentionally kills his targets after Guardian has fought them, putting the blame on Guardian.
Freudian Excuse Is No Excuse: Guardian tells him that he understands his pain over losing the woman he loved, but that doesn't excuse him killing criminals because of it.

Judge, Jury, and Executioner: Chiefly because he thinks the legal system has failed.
Malevolent Masked Man: His armor has a thick helmet.

Roaring Rampage of Revenge: For the acquittal of his wife's murderer.
Rogues' Gallery Transplant: Variation - is actually a D-list Superman villain from the comics, yet his primary feud are against James Olsen and Maggie Sawyer.
Sociopathic Soldier: Being consumed by vengeance has nullified his regards to others.
We Can Rule Together: When he finally encounters Guardian, he tells him that he would have liked them to be allies. However, James's Thou Shall Not Kill principle makes such a thing impossible.
Well-Intentioned Extremist: He believes that he is making the city a safer place by killing criminals who escaped justice.
You Fool!: Calls Guardian a fool for saying that killing people is not the right way to honor a deceased loved one.

Portrayed By: Chad Lowe

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

Appearances: Supergirl

A former lawyer who turned to alcoholism before he found a new purpose in his life after being rescued by Supergirl.

Affably Evil: He's easily one of Supergirl's nicest human enemies. When Kara visits him in prison, he claims he already forgot the name of her civilian identity, but he calls her business number when he wants to warn her about Reign, meaning he lied to ease her mind.
The Bus Came Back: Warns Kara about Reign in the mid-season finale of Season 3. And later joins Reign.]]
Cult: The leader of one who hails Supergirl as a Messiah and a God.
The Cynic: Before being saved by Supergirl, he was at a low-point due to being recently divorced after discovering that his wife was cheating on him with her personal trainer.
Desperately Looking for a Purpose in Life: The reason why he founded the Cult. Whether by outside influences or his own design, he has nothing left in his life outside of worshiping Supergirl.
The Dragon: To Reign, after his Face–Heel Turn. And later briefly to Selena, before she disposes of him.
From Nobody to Nightmare: From an alcoholic ex-lawyer to a dangerous Cult leader.
The Fundamentalist: Takes his beliefs to dangerous extremes, encouraging people to purposely endanger their lives to experience being saved by Supergirl, and even planning to blow up a stadium in order to make her save hundreds at once. He later turns on Supergirl and allies himself with Reign, believing Reign's rule over Earth is preordained.
My God, What Have I Done?: After seeing Kara bleed under the effects of kryptonite, he realizes how he screwed up and helps Kara and Alex dispose of the bomb. His faith isn't entirely shattered, however; now he sees it as his mission to guide Kara toward her destiny, even offering her information on Reign that Kara herself couldn't find with Krypton's vast library at her disposal.
Not Quite Dead: In the finale, he is shown to have survived being blasted by Heat Vision, drags himself into the Kryptonian Ship and sends a distress call. Its not shown whether he ultimately survives his injuries or not.
Obliviously Evil: He's a nice and compassionate man who genuinely does not understand why encouraging his flock to endanger themselves and others for their belief is wrong.

Secret-Keeper: He knows Kara is Supergirl at a glance, but promises to respect her desire for privacy.
Well-Intentioned Extremist: He is not actually Kara's enemy. However, ever since Kara saved his life, he started to worship her as a god and offers her his help because he sees that she is in conflict with her civilian life and her life as a superhero. In his attempt to make more people believe in Supergirl, he endangers a lot of other innocent people and the members of his cult, though, and Kara almost dies when he intends to detonate a bomb laced with kryptonite.
You Have Outlived Your Usefulness: On the receiving end by Selena. After fulfilling his part in resurrecting Reign, she seemingly kills him with her Heat Vision.

Jacqueline Nimball

Species: Human

Portrayed By: Brooke Smith

First Appearance: "Schott Through the Heart" (Supergirl 3x14)

Appearances: Supergirl

A former maintenance worker at Van Kull Maximum Security Prison who became the apprentice of Winslow Schott Sr. and promised him to continue his work after his death.

Actor Allusion: Mary calls Jacqueline "Buffalo Bill" at one point. Her actress Brooke Smith previously played a victim of someone by that name.
Adaptational Job Change: In the comics, Jack Nimball was a petty crook before becoming the second Toyman. The show version was a maintenance worker at the National City penitentiary.
Adaptation Name Change: Due to the Gender Flip, the character's first name is "Jacqueline" instead of "Jack".
Adaptation Relationship Overhaul: In the show, Jacqueline Nimball was taken on as an apprentice by the first Toyman Winslow Schott Sr. so that she could succeed him and continue his work after his death. In the comics, Jack Nimball never met Winslow Schott before becoming a supervillain and actually assumed the identity of the second Toyman without his consent, with Winslow considering him a disgrace to the name of Toyman and eventually killing him.
All There in the Script: Her name is never spoken out loud during the episode and is only revealed in the credits.
Comic-Book Movies Don't Use Codenames: Despite being Toyman's apprentice and successor, she is never directly referred to as "Toyman" herself, unlike her comic book counterpart.
Deadly Remote Control Toy: Once the Superfriends arrive at the factory, Jacqueline sends all kinds of weaponized remote-controlled toys after them, such as planes that explode on contact and cars that shoot fire and missiles at them.
Did You Actually Believe...?: When Mary laments what she and her son are enduring because of her, Jacqueline mocks her for believing that she could have compassion for them despite the way they treated Winslow Sr.
Jacqueline: You really think you're a pair worthy of sympathy? Or mercy?
Do Not Adjust Your Set: After trapping Mary, Jacqueline takes control of the DEO screens to show Winn a video of his captured mother and demand that he surrender himself in exchange for her life.
Even Evil Has Loved Ones: She holds her mentor Winslow Schott Sr. in high regard, calling him a "once-in-a-lifetime mind". She's willing to carry out his wishes even after his death, and expresses her contempt towards Mary and Winn for treating him so poorly.
Fire-Breathing Weapon: One of the deadly toys she sends after Winn and James is a remote-controlled car that shoots flames.
Forced to Watch: She plans to kill Winn in front of his mother, as his father had intended should she come near him.
Jacqueline: [To Mary] I'm gonna kill your son. I'm gonna make you watch, just like Winslow wanted.
From Nobody to Nightmare: She was a mere maintenance worker before Winslow took her under his wing and turned her into a dangerous supervillainess.
Gender Flip: In the comics, the second Toyman is Jack Nimball, a man.
I Have Your Wife: She captures Mary and uses her as a hostage to force her son Winn to go to her lair where she plans to kill him.
Killer Yo-Yo: Like Winslow Sr, she uses a yo-yo as a weapon against Winn at the end of the episode. However, it turns out that Winslow did not teach her about the hidden blades inside.
Mad Bomber: Like her predecessor, she's a lunatic who often uses explosives. In fact, her very first crime was to detonate a bomb hidden inside Winslow's coffin in an attempt to kill the people attending his funeral.
Moral Myopia: According to her, Winn and Mary are awful people who don't deserve any sympathy because they wanted to stay away from Winslow Sr. Never mind that he was a ruthless murderer who abused them and threatened to kill them more than once.
Nerves of Steel: She remains unfazed when Mary arrives in the factory and points a gun at her, probably because she knows that she's about to get caught by the trap set for her.
Not Wearing Tights: She never wears anything resembling the yellow and black jester costume from the comics.
Rogues' Gallery Transplant: Like his predecessor, Jack Nimball was an enemy of Superman in the comics rather than Supergirl.
Spared by the Adaptation: The comics version of Jack Nimball was assassinated by Winslow Schott after a few appearances. In the show, Jacqueline Nimball survives her sole episode and actually outlives Winslow Schott Sr.
Undying Loyalty: She appears to be very loyal to her mentor Winslow Schott Sr. and is even willing to carry out his wishes after his demise.
Why Don't You Just Shoot Him?: Jacqueline opts to simply shoot Winn and Mary once Winn frees Mary from the claw. Winn mocks her for her lack of showmanship as a stalling technique so he can summon the repaired robot monkey to grab her gun.

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

Appearances: Supergirl

An ex-employee of the law firm "Vang & Morales" with mental issues. He was fired due to his outbursts, and plans to use D.E.O.-based weapons to take revenge on his former employers.

Canon Foreigner: There are no characters named "Arthur Willis" in the comics.
Cop Killer: Downplayed. He tries to shoot a policeman with his rifle in his first scene, but Guardian manages to pushes him to safety. Still, Arthur is aware that doing this means his life is over.
Going Postal: He's a former member of a law firm who snapped due to his wife leaving him for being a workaholic and the firm keeps passing him over for promotion, so he obtained some weapons to go kill his former employers. Fortunately, J'onn manages to talk him out of it.
It's the Only Way: He claims to J'onn that using his guns against his former employers is the only way to gain respect. J'onn tries to convince him otherwise.
Arthur Willis: This is the only way for me to be heard!
J'onn: Arthur, if you pull that trigger, no one's gonna listen to a thing you have to say.
I've Come Too Far: When J'onn tries to convince him to surrender, Arthur initially refuses by pointing out that he tried to shoot a cop earlier, so his life is already over no matter what.
Motive Misidentification: At the beginning of the episode, Arthur Willis is spotted near a bank and is assumed to have been attempting a robbery. When his identity is tracked down later, the DEO realize that he was actually planning to attack his former office, which is in the same business plaza as the bank.

First Appearance: "Reality Bytes" (Supergirl 5x15)

A confrontational radio Shock Jock that gets powers after being zapped by lightning while being saved by Kara.

see the Smallville: Meteor Freaks page for the Earth-167 character who bears her name and background

Adaptational Attractiveness: Livewire usually has a more Ghoulish appearance in the canon comic line. Here, she retains her feminine appearance after her transformation which is a lot like her cartoon look, though less blue.
Adaptational Modesty: After becoming Livewire, she doesn't wear her Navel-Deep Neckline showing Leotard of Power of a costume. Instead, she goes full-on Civvie Spandex.
Adaptation Dye-Job: Before and after becoming Livewire. As Leslie, her hair was black when she was first introduced in Superman: The Animated Series and as Livewire it's (fittingly) electric blue, while here Leslie is blond and Livewire has bluish white hair.
Arch-Enemy: Kara considers her to be her nemesis. Certainly she's Kara's most recurring non-Arc Villain enemy.
Attack on the Heart: She often attempts to use her electricity powers to stop people's hearts from beating.
- After overpowering Supergirl during their second fight in "Livewire", she expresses an interest in making her heart stop beating.
  Livewire: I wonder if I have enough power to stop your heart.

  Livewire: You see, Cat, I'm still 50-50 if your heart's actually beat, but I'm gonna stop it anyway.
Berserk Button: Ever since the accident that gave her powers, Livewire has a particular hatred for helicopters, so much so that she tries to attack one without any provocation in "Worlds Finest".
Livewire: I hate helicopters!
Boring Insult: She calls Supergirl "boring" among other insults during their confrontation at the end of "Livewire".
Livewire: Your 15 minutes are up, you boring, weak…
Supergirl: Oh, shut up, you mean girl!
Breakout Villain: The most popular of Kara's nemesis. Said popularity is the reason why she was made Kara's most recurring foe.
Card-Carrying Villain: She makes no bone about the fact that she's a supervillainess. She even says that her team-up with Silver Banshee is like "an evil Taylor Swift squad" in "Worlds Finest".
Civvie Spandex: She's still wearing her casual clothes even as a supervillain.
Create Your Own Villain: She gave a Take That! to Supergirl on live radio which results to Cat demoting her to traffic report duties. During one of those duties, she was zapped by lightning along with Supergirl while the latter is rescuing her from the chopper she was riding. Said incident gave her powers. After realizing she now has powers, she vowed revenge on both Cat and Supergirl, making their lives hell if she gets the chance.
Dramatic Irony: Spent most of her time trying to kill Cat Grant and Supergirl, then she dies saving Supergirl.
Drinking on Duty: During the time she worked as a waitress in a diner to keep off Reign's radar in Season 3, Livewire would often take breaks at any time to go drink beers. Supergirl even calls her out on it when she comes to ask her for help and finds her with a bottle in her hand.
Supergirl: What, are you drinking on the job, Livewire?
Energy Beings: She can exist as pure energy, though she has to take physical form to do more than mess with electronics.
Enemy Mine:
- In "World's Finest", she agrees to join forces with Silver Banshee due to their common hatred of Cat Grant.
- She teams up with Supergirl and Psi to fight against Reign in Season 3.
Establishing Character Moment: As Leslie Willis, we are shown her radio show as the entire cast reacts in varying levels of anger as she callously rips on Supergirl.
Even Evil Has Standards: She intends on killing Cat Grant again in "World's Finest", but when Cat pleads for her life because she doesn't want her sons to be left alone without a mother, Livewire is visibly affected and starts to reconsider, unlike Siobhan.
Evil Feels Good: She clearly gets a rush from using her powers to get revenge on Cat.
Evil Is Hammy: Brit Morgan is clearly having a blast with the role.
Foil: To Kara Danvers. Both of them are protegees of Cat Grant, who tries to "push" them to greatness. Leslie has become cruel and vindictive in her attempt to "push" back, while Kara remains patient and friendly.
Forced to Watch: When she comes to confront Cat Grant at the end of "Livewire", she asks where Supergirl is as she was hoping to kill one of the two while forcing the other to watch.
Livewire: Where's your bodyguard?
Cat Grant: I didn't think she was necessary.
Livewire: Sucks, I really wanted one of you to watch the other one die.
Freudian Excuse: As a shock jock, Leslie has always been rewarded for being mean and nasty, leading Cat to feel she is to blame for Livewire's actions as the one who has been rewarding her for years.
A God Am I: By the time of Season 2, she has come to believe that her electricity powers make her a goddess, as she states to her therapist Dr. Haminton at the prison.
Livewire: [To Dr. Haminton] You know what that power makes me? A bad guy? Evil? It makes me a god!
Heroic Sacrifice: She does this to save Supergirl and is fatally injured by Reign's eyebeams. Supergirl even mourns her after her death.
Immaturity Insult: In "We Can Be Heroes", she calls Guardian and Mon-El a bunch of pathetic little boys after they get defeated and captured while trying to rescue her.
Livewire: You know what I love? Little boys who think they can do a better job than the woman who's an actual superhero. It's pathetic!
Instant Expert: She gains control of her powers remarkably quickly.
Jerkass: She starts the episode by going on a long rant about all the reasons she thinks Supergirl is awful and from her conversation with Cat, this seems to be her standard M.O.
Kryptonite Factor: Water really doesn't play well with Livewire.
Lightning Can Do Anything: From manipulating electronics to forming whips. This is given a justification in that she got zapped by lightning that was filtered through Kryptonian biology.
Lightning Lash: One of her favorite ways to use her powers is to create electric whips to restrain her opponents, which is what she does to Supergirl in Season 1, to the unnamed scientist who captured her in Season 2, and to the Fort Rozz prisoner Tormock in Season 3.
Living Battery: In "We Can Be Heroes", Livewire is captured by a Mad Scientist who uses her energy to empower both his Super Soldiers and himself.
Locked into Strangeness: Getting struck by lightning through Supergirl gave her white hair and electricity powers.
Mugging the Monster: Immediately after discovering her ability to move through wires, she finds herself in an alleyway. A lowlife attempts this trope on her, even commenting on the stupidity of someone as good looking as she was coming to that part of town. It doesn't end well for him.
Mystical White Hair: She has white/very light blue-ish hair and is a Psycho Electro.
Mythology Gag:
- Leslie's rebirth as Livewire is the same as in her first appearance, being struck by lightning through a Kryptonian just like in the similarly named debut episode for her character in Superman: The Animated Series. She was also introduced in that episode insulting Superman on her show.
- Her defeat in Livewire is also identical to her defeat in the same episode.
- She also gives a remarkably similar speech about her rebirth.
  Livewire: Leslie Willis is dead. Meet Leslie 2.0. ''
Never My Fault: Leslie blames Cat Grant entirely for her helicopter accident and wants to get revenge on her for it, even though she was the one who refused to listen to the pilot's cautionary advice which led to them being struck by lightning.
Nice Job Fixing It, Villain: After Kara spends two episodes struggling to restore her reputation after her Red Kryptonite-induced rampage, Livewire impulsively tries to shoot down a police helicopter. Kara takes the hit herself in front of a huge crowd, who start seeing her as a hero again.
Not Me This Time: Lucy blames the early stages of Myriad on her. She really has nothing to do with it, as she was obviously imprisoned at the time.
Not Worth Killing: After threatening to kill her prison therapist in "We Can Be Heroes", Livewire laughs and says she isn't really going to do it because it wouldn't be worth it.
Livewire: Freud, please, I'm not gonna kill you. Come on. It'd be so... pointless.
One-Steve Limit: Averted. She has the same last name as Arthur Willis, a minor villain from Season 3.
Politically Incorrect Villain:
- In her first scene, Leslie makes some homophobic comments towards Supergirl during her radio show.
  Leslie: I mean, she does kind of give off a Sapphic vibe, with that big ol' butch "S" chest plate.
- During her appearance in Season 3, Livewire makes some pretty distasteful remarks towards the male inmates of Fort Rozz who were killed by the blue star.
Psycho Electro: She's got a few screws loose after she gets her powers.
A Pupil of Mine Until She Turned to Evil: She is Cat Grant's first protegee gone bad, the second being Siobhan Smythe aka Silver Banshee. Cat later lampshades this.
Redemption Rejection: During their first fight, Kara offers to help her. She says she's "good as is."
Redemption Equals Death: She jumps in front of Supergirl to save her from Reigns eye beams, she dies moments after Reign flees from the battle after Psi uses her abilities on her.
Ride the Lightning: Is able to travel by wire, or even hijack television screens to plaster her face over it.
Rogues' Gallery Transplant: Livewire is usually a Superman villain, at least until her Heel–Face Turn in the comics, who originated in Superman: The Animated Series, before popularity made her a canon comic character. Her creation in this show is almost exactly like it was in the cartoon, except the lightning passed through Kara instead of Superman.
Shock and Awe: She's got electricity powers.
Shock Jock: Of course, crossing Cat Grant by going after Supergirl had gotten her transferred to traffic helicopter.
Shout-Out: In her first episode, she uses her electricity whips in a way that resemble the villain Ivan Vanko a.k.a. Whiplash from Iron Man 2.
Slasher Smile: She can't help herself but enjoy being a Psycho Electro.
Spoiled Brat: Cat Grant sees her like a daughter who wasn't put limits.
Statuesque Stunner: She stands 5'8 1/2 and one guy even comments on how hot she is.
Taking the Bullet: She jumps in front of Reign's eye beams to save Supergirl.
Tall, Dark, and Snarky: On paper, she's a sure-in Statuesque Stunner given her height (she's 5'8 1/2, a little taller than Kara herself) and beauty. However, her Jerkass behavior pretty much overwhelm every attractive traits she has.
That Man Is Dead: Livewire claims that Leslie Willis died on the helicopter and thinks of herself as "Leslie 2.0".
This Is Gonna Suck: Has this kind of reaction when Guardian is the one who comes to her rescue instead of Supergirl in "We Can Be Heroes".
Livewire: Great. I'm screwed.
Thrown Out the Airlock: In the episode "Fort Rozz", Livewire gets briefly ejected into space while fighting a Kryptonian demon on the titular prison, but she turns into electricity and manages to get back on board.
Transhuman Treachery: Describes her transformation as "ascendance" while attacking Cat Grant.
True Blue Femininity: All her outfits has blue in it in one form or another. However, she does not have both the fairness and gentleness usually associated with the trope.
Ungrateful Bastard:
- She probably would have died in the helicopter accident without Supergirl's intervention, and yet that doesn't stop her from trying to kill her in most of her appearances.
- Siobhan Smythe accuses her of being this in "World's Finest" when Leslie threatens to electrocute her right after she releases her from her DEO cell.
  Siobhan: I need your help.
  Leslie: I can help you catch on fire!
  Siobhan: You should be a little more grateful since I'm the one who broke you out of your hamster wheel.
Villainous Friendship:
- While the two occasionally bicker, Livewire does refer to her partner-in-crime Silver Banshee as a friend in "Worlds Finest".
- In Season 3, she mentions that some of the criminals who were killed by Reign were friends of hers.
Virgin-Shaming: During her roast of Supergirl in her first appearance, Leslie mocks the superheroine for her "lack of sexuality". Cat Grant doesn't take it well.
Villain Team-Up: With Silver Banshee.
Weaksauce Weakness: Can be incapacitated by little more than a garden hose.
White Hair, Black Heart: She's a Psycho Electro with a Mystical White Hair.
Who Are You?:
- After Siobhan Smythe breaks her out of her DEO cell with her sonic screams in "Worlds Finest", Livewire is understandably curious to know who she is.
  Livewire: Who the hell are you?
  Siobhan: Siobhan Smythe.
  Livewire: It's like your parents knew you'd grow up to be a big snob.
- She naturally asks this to Guardian when he comes to rescue her from the scientist in "We Can Be Heroes", as she was in jail when he started his superhero career.
  Livewire: Who are you? Where is Supergirl?
  Guardian: She's busy. I'm Guardian.
- When Mon-El shows up shortly after, she asks him the same thing.
  Livewire: The hell are you supposed to be?
  Mon-El: I'm the other Superman... in training.
With Great Power Comes Great Insanity: Step 1) Realize you have superpowers. Step 2) Try to murder your boss. Apparently, Evil Feels Good. Really good.

Bizarro

Species: Metahuman

Known Aliases: Bizarro, Jane Doe, "Supergirl"

Portrayed By: Hope Lauren (original form), Melissa Benoist (as "Supergirl")

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

Appearances: Supergirl

A clone of Supergirl created by Maxwell Lord to discredit her.

Black Eyes of Evil: Once she's corrupted by green kryptonite, her eyes turn completely black.
Clone by Conversion: She was made through a combination of gene splicing and plastic surgery.
Composite Character: Slightly. The original Superman-based Bizarro apparently doesn't exist here, leaving her to simply have that name instead of the comics' Bizarro-Girl.
Evil Knockoff: Lord created her to ruin Supergirl's reputation and ultimately kill her. She has Supergirl's basic powers, but her Eye Beams freeze and she breathes fire.
Facial Horror: Getting shot with kryptonite causes her skin to turn grey, and her face starts cracking off, which is a reference to the original Bizarro's look.
Hulk Speak: On account of being comatose and brain-dead when Max picked her up. Getting her to understand language was impressive in itself.
Nature Versus Nurture: Despite Lord's best attempts to condition her into a killing machine, she is not an evil person at heart and only ever attempts to kill Supergirl. She even stops fighting Supergirl in their first encounter because Supergirl is trying to rescue some civilians. James tries to appeal to this side of her when she kidnaps him.
Psychopathic Manchild: As always the case with any Bizarro.
Tragic Monster: Kara is quick to point out that she's a pure victim of the situation, as a severely brain-damaged woman who's been manipulated into being a soldier in Maxwell Lord's war. After she's defeated, the DEO returns her to her comatose state hoping they can find a way to reverse what was done to her.
You No Take Candle: Veers between this and a childlike patois.

Silver Banshee

Siobhan Smythe / Silver Banshee

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

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

"All my life, I thought I was cursed. But now I see I was cursed for the better."

Species: Metahuman

Known Aliases: Silver Banshee, "Shrieky"

Portrayed By: Italia Ricci

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

Appearances: Supergirl

A new hire at CatCo Worldwide Media who clashes with Kara and later Supergirl.

Adaptation Dye-Job: In her 'civilian' guise comicbook Siobhan has white hair and blue eyes while TV Siobhan has brown hair and brown eyes. Justified Trope as this version could be one of the so-called "black Irish."
Adaptation Personality Change: In the New52 version of Supergirl, Siobhan Smythe is one of Kara's first friends after she arrives on Earth. Here, she hates Kara and eventually becomes Silver Banshee.
Adaptational Nationality: The New52 version of the character is an Irish girl who emigrated to America in her late teens. Here she is American of Irish descent.
Adaptational Villainy: As part of her Composite Character nature. She shares her name with the New52 Siobhan who is a Nice Girl and Kara's friend. In every other aspect she more closely resembles the villainous Siobhan MacDougal of the older comics.
Alcohol-Induced Idiocy: After her attempt to frame Kara for bad-mouthing Cat is foiled by Winn in "Manhunter", Siobhan gets drunk and goes up to the roof of her building to yell at Supergirl as she flies by. Unfortunately, she gets dangerously close to the edge and ends up stumbling and falling off the roof. She's certainly lucky that her powers activated for the first time at that very moment, otherwise her drunkenness would have led to her death.
Alliterative Name: Siobhan Smythe.
Aloof Dark-Haired Girl: She doesn't give a shit about other people unless they can benefit her.
Ambition Is Evil: She dreams of becoming a powerful figure.
Birds of a Feather: She ends up in a relationship with Winn due to the two of them having messed-up family lives.
Celebrity Paradox: Cat mentions The X-Files early in Season One despite the fact that her actress' Real Life husband is part of that show's Sequel Series^note.
Commonality Connection:
- She and Winn grow closer as they realize they both have issues with their fathers.
- She bonds with Livewire over their shared enmity with Cat Grant and Supergirl in "World's Finest".
Composite Character: She's named Siobhan Smythe, who was Kara's friend in the New52 comics. However, she is Kara's enemy here, making her more similar to Siobhan MacDougal, the Silver Banshee of the original comics.
Cursed with Awesome: Her Silver Banshee powers come from an Irish ancestor pissing off a real banshee; now the women of her family are cursed to be unpleasant, and when they feel they have been wronged, the Banshee power develops until the one who wronged them is dead.
Cynicism Catalyst: When she was 17, Siobhan caught her dad cheating with his personal assistant. This convinced her that everyone is selfish and any kindness is a cheap façade.
Dark Action Girl: Once she becomes a supervillainess, she is able to put up a decent fight against Supergirl herself.
Deceptive Disciple: She seemed a reliable assistant, but she is willing to sell a story to Perry White, a rival to CatCo. She gets fired and Perry White assures Cat that he would not hire Siobhan.
Enemy Mine: She convinces Livewire to team up with her due to their common hatred for Cat Grant. She even Lampshades this trope just before she goes to break her out of the DEO prison.
Siobhan: The enemy of my enemy… is my new partner.
Even Evil Has Standards: When bystanders come between Supergirl and the villains in "World's Finest", Livewire has no problems trying to kill them, but Silver Banshee hesitates and doesn't attack, suggesting that she's not as evil as her partner
Evil Cannot Comprehend Good: As Siobhan is so selfish and her opinion of humanity so low, she finds the concept of people acting with altruism and honour laughable, no matter how many times they prove her otherwise.
Evil Counterpart: To Kara Danvers, of course. Both of them work as Cat Grant's assistant, both of them have been the objects of Winn's affections, and both secretly have superpowers from their lineage. The difference is that while Kara is a Nice Girl who uses her powers to help others, Siobhan is a selfish Alpha Bitch who wants to use her powers to kill people.
Evil Makeover: Gets one from Livewire after they team up.
Freudian Excuse: She walked in on her father having an affair with his assistant. Afterwards, her father promised Siobhan that he loved her and her mother, and would end the affair, but their relationship was never the same again. To make matters worse, Siobhan finds out in "Solitude" that her father was a platinum member of an infidelity website anyway, meaning he lied to her for years.
Fighting Irish: She has Irish heritage and her power comes from an old Irish curse.
From Nobody to Nightmare: Cat had no idea whom she had hired to be her assistant.
Go-Getter Girl: She is a very driven person.
Height Insult: She makes a crack about Winn's short stature the first time they interact in "Solitude".
Winn: How's it going, Siobhan?
Siobhan: I'm sorry. I have difficulty making conversation with men under six feet tall.
Hereditary Curse: Her powers originate from one, due to an ancestor who got on the wrong side of a banshee. Whenever a woman in the Smythe family is wronged (which is often due to the fact that they are also cursed to have unlikable personalities), they are granted banshee powers until the one who wronged them is dead. Refuse to take their revenge, and the banshee spirit drives them insane.
Humiliation Conga: Circumstances surrounding her firing, and her actions in an attempt to win her job back, blew up on her face big time.
Hypocrite: She labels Kara as a "mean girl," despite the fact that she had been treating Kara like dirt since the day they met.
I'm Not Here to Make Friends: Said word-per-word towards Kara, and it shows.
Inferiority Superiority Complex: She loves acting smug, but she's easily demoralized when faced with failure.
In Name Only: Literally the case with her New52 counterpart given she has a different nationality, personality, morality, job, family history and even hair colour from the comic Siobhan. She has a bit more in common with Siobhan MacDougal (being evil for instance) but is still quite radically altered.
It's All About Me: She exhibits this in a conversation with Kara about how she intends to become the next Cat Grant, and dismissively says that Kara will be her underling.
Jerkass: She firmly establishes herself as this when, after Cat fires her, she tries to get back at Kara by impersonating her in a nasty email.
Jerkass to One: During her time at CatCo, she acts like a total suck-up to both Cat Grant and James Olsen, and while she starts out rather dismissive of Winn she eventually grows closer to him and even dates him. On the other hand, she seems pretty much incapable of talking to Kara without being obnoxious to her.
Man of Kryptonite: Her powers are of magical nature, which Kryptonians are vulnerable to. This allows her to make Supergirl's ears bleed with her sonic screams and to send her flying with a punch.
Make Me Wanna Shout: She finally reveals her powers at the end of "Manhunter", using her screams to break what would have otherwise been a rather nasty fall.
Maybe Magic, Maybe Mundane: Her Silver Banshee look. We don't know if she actually transformed or if it's just costume and makeup.
Mistaken for Aliens: After seeing her survive a fall from the top of a building without a scratch, Winn assumes Siobhan may be a Kryptonian or some other type of alien and takes her to the DEO base for some tests, which confirm that she is fully human.
Mistaken for Suicidal: At the end of "Manhunter", Winn sees a drunk Siobhan on the roof of her building and assumes she intends to jump to her death due to losing her job. He tries to talk her out of it, but she reveals that this wasn't her plan at all.
Winn: Siobhan, no, no, no! Stop. Stop.
Siobhan: Seriously? I have too much self-esteem to kill myself.
Moral Myopia: She considers Kara exposing her attempt to send her "evil Supergirl" story to the Daily Planet to be the act of a "mean girl," but shortly after tries to forge an insulting e-mail to Cat so Kara will be fired.
Never My Fault: She refuses to take any responsibility for the duplicitous actions that got her fired and nearly arrested, instead blaming everything on Kara and wanting revenge.
No Pronunciation Guide: Kara has no idea how to pronounce her name when she first reads it, and is surprised that Cat is able to pronounce it correctly.
Outside-Genre Foe: Mildly. She's the first villain in the show whose powers have a magical rather than a scientific explanation. However, Supergirl and the Flash have no problem defeating her like any other metahuman criminal.
Persona Non Grata: After intending to sell a scoop to a rival company and impersonate Kara Danvers, Siobhan Smythe is no longer well-received in CatCo.
Primal Scene: She tells Winn that she caught her father literally in the act with his personal assistant.
Professional Butt-Kisser: She knows how to suck up to the higher-ups at CatCo.
A Pupil of Mine Until He Turned to Evil: She is the second of Cat Grant's protegees to turn evil, with Leslie Willis aka Livewire being the first. Cat even Lampshades this at one point.
Put on a Prison Bus: After her defeat in "World's Finest", Kara mentions that Silver Banshee was taken to the National City Prison where they found a way to lock up superpowered individuals thanks to Barry Allen's help. She never reappears afterwards.
Redemption Rejection: As Silver Banshee, she shuts down any attempt to help her.
Rewarded as a Traitor Deserves: A non-fatal example. After Cat discovers that Siobhan planning to betray her, she got herself immediately fired.
The Rival: For Kara in CatCo.
Rival Turned Evil: She goes from a competing assistant to the supervillain Silver Banshee, which was announced weeks before she even appears.
Role-Ending Misdemeanor: In-universe, intending to sell information on Supergirl to a rival news outlet and being disgracefully fired from CatCo and made many media employers wary of hiring her.
Romantic False Lead: For Winn. The two have a brief relationship, which is promptly followed by her becoming a villain.
Sassy Secretary: She gets the secretary job done much more efficiently than Kara, and she won't hesitate to rub it in her nose. However, this only lasts until the job moves beyond butt-kissing, at which point her weaknesses start to show.
Second Love: She's the first girl that interests Winn after he lets go of Kara. Unfortunately for him, she goes to the dark side.
Sexy Secretary: She's easy on the eyes.
Skilled, but Naive: She's a good PA and a great Professional Butt-Kisser, but she can't match Kara's years of experience at learning Cat's every quirk and pet peeve.
Small Name, Big Ego: Despite acting and talking big, she doesn't really live up to her boasts.
Smug Snake: She always displays an aura of overconfidence when around Kara, despite not being nearly as cunning as she thinks she is; her Wrong Genre Savvy acts quickly come back to bite her in the ass.
Super-Strength: She's able to send Kara flying with a punch.
Traumatic Superpower Awakening: Her power awakens and saves her at the last minute from what would have otherwise been a rather nasty fall.
Ungrateful Bastard: As Winn points out, she doesn't even bother to thank him after he helped her with a copy machine problem in "Solitude". In her defense, she was feeling particularly upset that day due to finding out that her father cheated on her mother again.
Winn: "Thank you" would be nice...
Villain Team-Up: With Livewire.
Woman Scorned: She is pretty mad at Winn for choosing to help his friend (and former crush) Kara rather than her when she tries to frame her up in "Manhunter", and threatens to kill him over it. Once she becomes a supervillainess in the following episode, she lashes out violently at Winn both times she storms into the CatCo building.
Wrong Genre Savvy: The cause of her downfall as she assumes being an Alpha Bitch and Professional Butt-Kisser will make her "the next Cat Grant" in no time, not grasping she doesn't have the smarts, talent or dedication to be anywhere near Cat's level.
- When Cat is uncertain about publishing a story of Supergirl gone rogue, Siobhan tries to sell it to the Daily Planet, thinking they'll love a scoop on a rival. She doesn't expect Perry White to have the integrity to call Cat and tell her about the deal.
- Cat openly lampshades how Siobhan thinks she's the "plucky heroine" who will make a big splash with the story and Cat will be so impressed by her gumption that she'll hire Siobhan as a full-on reporter. Instead, Cat calls Siobhan a "backstabbing imp" and fires her.

Parasite

Rudy Jones / Parasite

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

"The organism seems to be absorbing my red blood cells, rewriting my DNA into something new. We're not two distinct beings any longer. We've become one. One greater than the sum of its parts."

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

"We are Parasite."

Species: Metahuman

Portrayed By: William Mapother

First Appearance: "Changing" (Supergirl 2x6)

Appearances: Supergirl

A climate change expert who is infected with an alien parasite.

see the Arrowverse: Mystics page for Jacob Shaw, the Earth-1 character who bears his physical appearance

see the Smallville: Meteor Freaks page for the Earth-167 character who bears his name and background

Adaptation Deviation: In the comics, Rudy was a STAR Labs janitor who became a mutant when exposed to radioactive waste. The Supergirl version is infected with a literal symbiotic parasite akin to the facehuggers from Alien.
Adaptational Nice Guy: He has good intentions when stopping climate change deniers, since for him they are harming the planet.
Back for the Finale: He is one of the villains summoned by Lex Luthor to fight the Superfriends in the final battle of the last episode of Supergirl.
Car Cushion: After being sent flying by Guardian's shield, Parasite lands on a nearby car.
Celebrity Paradox: Lost was mentioned during the Arrow series premiere, even though his actor plays a major antagonist there. However, Arrow is on an Alternate Universe, so the paradox might be a subversion.
Comic-Book Movies Don't Use Codenames: He's only referred to as Parasite once, by himself, when fully transformed and trying to kill Mon-El.
Defeat Equals Explosion: His body explodes when Supergirl makes him absorb too much plutonium.
Evil Makes You Monstrous: Absorbing innocent people's life energy ends up turning him into some kind of gigantic purple monstrosity.
Identical Stranger: His actor also portrayed Jacob Shaw in Constantine (2014).
Immune to Bullets:
- When Alex tries to shoot him after he absorbed Kara's powers, the bullets bounce off him like it's nothing.
- After his resurrection by Mr. Mxyzptlk, he starts another rampage and gets shot by several cops, which has absolutely no effect.
In a Single Bound: When Guardian joins the fight and throws an explosive at him, Parasite makes an impressive jump to get to him, though he gets pushed back by his shield.
More Teeth than the Osmond Family: For each of his Nested Mouths, no less.
Nested Mouths: His Parasite form has several of them.
No, You: His answer when Supergirl tells him that he is supposed to be dead during his second appearance.
Supergirl: Hey! I thought you were dead.
Parasite: You're the one who's dead!
Power High: It's clear that he very much enjoys absorbing the powers of a Kryptonian.
Rudy Jones: Such power... We like it!
Power Parasite: He has the ability to drain energy from his victims.
Punch Catch: Once it's made clear that Rudy Jones has been infected and is killing people, Supergirl tries to punch him, but he grabs her fist and proceeds to absorb her strength.
Purple Is Powerful: As with most versions of Parasite, he has a purple color scheme.
Rogues' Gallery Transplant: Parasite is usually a Superman villain. He also fought the Linda Danvers version of Supergirl, but never the Kara Zor-El version of Supergirl.
Royal "We": After realizing that he and the parasite are merging to become a single entity, he starts referring to himself as "We".
Rudy Jones: No. No, we don't accept that.
Jones's boss: "We"? You and who else?
Rudy Jones: We.
Shout-Out: Both to Alien and The Thing — an extra-terrestrial found frozen in an icy environment in the guise of a dog that kills most of the scientists working there, and when its true monstrous form is revealed, it opens its maw hiding even tinier mouths.
Small Role, Big Impact: While he is only the villain for one episode of Season 2, it was because he had absorbed J'onn's life force that M'gann was forced to transfuse her blood into him, which has major repercussions on the rest of the season as it almost turns J'onn into a White Martian and consequently reveal M'gann's true nature.
Starter Villain: He is the first enemy faced by both Mon-El and Guardian once they decide to become superheroes.
Super-Strength: After absorbing Kara's powers, he becomes strong enough to crush Alex's gun with his bare hands. He becomes even stronger when he absorbs Kara and J'onn's powers at the same time and turns into a hulking monster, throwing cars around with ease.
Was Once a Man: Once an ordinary human, until he became infected with an alien parasite.
Well-Intentioned Extremist: Most versions of Rudy were apathetic citizens or petty criminals at worst. Rudy here is a fanatical climate change scientist who believes he is saving the world, and eliminates anyone who might impede his scientific work.
Would Hurt a Child: During his rampage at the end of his first episode, he picks up a car and throws it at a young girl. Thankfully, Mon-El manages to catch it before impact and tells the girl to run away.

Psi

Gayle Marsh / Psi

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

Species: Metahuman

Portrayed By: Yael Grobglas

First Appearance: "Triggers" (Supergirl 3x2)

Appearances: Supergirl

A bank robber who has the ability to instill fear in others. Born in Skokie, Illinois, the same as her comic counterpart.

Adaptation Dye-Job: All comic versions of Gayle have black hair. Here she has light blonde hair.
Adaptational Villainy: In the comics, Gayle uses to play the role of misunderstood antagonist or naive girl who has been deceived into doing bad things. In the show she's an outright criminal.
Big Damn Heroes: Saves Supergirl from Reign by causing her fears to manifest, which causes her to flee.
Enemy Mine: Is recruited alongside Livewire by Kara and Imra to assist them during their mission to Fort Rozz.
Mind over Matter: She even uses the phrase on Kara. Becomes an Ironic Echo when Kara overcomes her powers and then knocks her out.
Pet the Dog: Actually saves Kara instead of just running away and offers her condolences after Leslie's death.
Person of Mass Destruction: During the climax, she assaults an entire street, including a construction worker operating a wrecking ball, which wreaks some serious havok.
Psychopathic Womanchild: Her behaviour is very off, citing child stories and acting like a little girl playing with her toys.
Supernatural Fear Inducer: Her powers. Her fear waves are sometimes so strong that they can physically knock back a person, even a superpowered one like Kara.
Suspiciously Similar Substitute: After Livewire's death Psi seems to be taking up the mantle of Kara's slightly mentally ill nemesis with the potential for future redemption. Their physical resemblance additionally contributes to that.

Villain Has a Point: Supergirl concedes that Amy's manifesto has a lot of good points in it.
