The Original Rogues
A group of criminals armed with special weaponry, who time and again would clash with Team Flash.
- Aborted Arc: Their formation has been cut short, since Cold and Heat Wave have been shunted off to Legends of Tomorrow.
- Appropriated Appelation: When Barry offhandedly calls Snart's little gang a "Rogues Gallery", Snart remarks that it's "cute" and actually calls his gang that in Rogue Air
- Badass Normal: The three members (so far) aren't even metahumans; just career criminals whose powerful weaponry makes them a threat to the Flash. In Rogue Air Snart frees the meta-humans so they can repay the favor by joining his gang. Rainbow Raider and Weather Wizard consider the offer, with Weather Wizard later breaking Snart out of prison in "Running to a Stand Still" to pay him back.
- Chromatic Arrangement: Leonard is associated with blue, Mick is to red, and Lisa is to gold which is a shade of yellow.
- Debut Queue: Each appearance of the group has seen a new member joining (though not strictly debuting in the series - Mick and Lisa both showed up in The Stinger of a previous Rogues episode first).
- Gadgeteer Genius: Zig-zagged. Most of their weapons were stolen from STAR Labs. But they are smart enough to become familiar with them and repair them, not just build any from scratch themselves. So after the police confiscated their weapons, Cold arranges to have Cisco kidnapped so he can build them new ones.
- Guest-Star Party Member: Snart offers membership to Weather Wizard and Rainbow Raider when he frees them in "Rogue Air". Weather Wizard returns the favor by breaking Snart out in "Running to Stand Still" along with the Trickster offering to team up. Although at that point Snart had turned over a new leaf and declines.
- Idiosyncratic Episode Naming: So far each episode they show up in has the word "Rogue" in the title.
- Put on a Bus: Lisa was last seen riding out of town on a motorcycle at the end of "Family of Rogues", while Rory and Snart were transplanted over to "Legends of Tomorrow''.
- Recurring Character: Unlike the most of the meta-humans who tend to be one off villains of the week, the Rogues are recurring and persistent foes.
- Two Guys and a Girl: Leonard and Mick are the guys, while Lisa is the girl.
- Villain Team-Up: Even though he beat the Flash in his first appearance all by himself, Snart is smart to recognise strength in numbers so he slowly begins to form his own gang. He first starts with Mick and then brings his sister Lisa along for the ride.
- Villainous Legacy: Ever since their disbandment / Heel–Face Turn various other super criminals have been trying to take their place in Central City but none so far have quite the skill to pull it off.
Lisa Snart / Golden Glider
Known Aliases: Golden Glider
Played By: Peyton List
First Appearance: "Rogue Time" (The Flash 1x16)
Appearances: The Flash
The younger sister of Leonard Snart, who busts her brother and Heat Wave out of a prison transport. Later she enlists the help of Team Flash to rescue her brother from their cruel father.
- see Smallville: Lanes for Lucy Lane, the Earth-167 character who bears her physical likeness
- Abusive Parents: Her father emotionally and physically abused her just as much as he did her older brother.
- Adaptation Dye-Job: In the comics she is blonde, which together with her yellow/orange costume and ice-skater theme led to her alias Golden Glider (later shortened to Glider). Here she is a brunette, but briefly wears a blonde wig.
- Affably Evil: Snarkiness aside, she's genuinely fond of Cisco, and is sincerely grateful to him and the team for saving her life in season 2.
- Alliterative Name: As Golden Glider.
- Aloof Dark-Haired Girl: Once she no longer needed her facade, she never stopped snarking at people.
- Appropriated Appellation: She asks Cisco to give her a nickname after her gun's powers Golden Glider.
- Dark Action Girl: By the sounds of it, she was able to handle all the security surrounding the prison transport without breaking a sweat — and with a lot of bullets. This is confirmed in "Rogue Time", where she shows herself to be about as good at fighting and using guns and gadgets as her brother.
- The Driver: She has a commercial operator's license and knows how to drive big trucks.
- Drives Like Crazy: While Lisa actually is good at driving, she just enjoys driving recklessly more.
- Even Evil Has Loved Ones: She cares about her brother and gets Barry's help in saving him from their father.
- The Faceless: In her debut appearance.
- Foe Romance Subtext: With Cisco.
- The Ghost: In Legends of Tomorrow she's constantly mentioned but never makes an appearance. Even when Pilgrim targets the Legends' loved ones she fails to appear in person.
- Gold Makes Everything Shiny: Gets Cisco to build her a gun that encases her targets in a gold-like substance.
- Hell-Bent for Leather: Wears a heavily leather-y outfit in her official appearance.
- Honey Trap: Does this to Cisco to get Cold and Heatwave's guns back. Later she develops genuine feelings for him.
- In Name Only: Aside from her codename and being Captain Cold's younger sister, she pretty much has no resemblance to her comics counterpart who utilized a pair of high-tech skates where her Glider name came from along with an assortment of other gadgets, none of which included a gun that coated its target in gold.
- Letter Motif: With her big brother, Leonard. Their father is named Lewis.
- Long Bus Trip: She hasn't returned to scene after being helped by Team Flash in "Family of Rogues".
- Morality Pet: Despite being a villain herself, Lisa serves as this to Cold. She is literally the one person in the world he genuinely cares about.
- Mythology Gag:
- Lisa's first appearance, involving her easily busting Captain Cold and Heat Wave out of a prison transport, is just like her New 52 debut as The Glider.
- Unlike most other villains in the show, her gimmick is significantly different (she doesn't "glide", either through skating or astral projection) so her gold gun is more of a nod to the "Golden" part of her alias.
- Never Got to Say Goodbye: Leonard dies performing a Heroic Sacrifice in the penultimate episode of Legends of Tomorrow Season 1. What's worse is it is unclear if Mick told her about it when he briefly returns to 2016 or she's completely Locked Out of the Loop.
- Odd Name Out:
- Sibling Team: With Captain Cold.
- The Stinger: She first appears at the very end of Episode Ten, though mostly off-screen.
- Villainous Crush: On Cisco.
- Was It All a Lie?: Originally her interest in Cisco was just part of one of her brother's evil schemes. Later she reveals the feelings become real...and mutual.
- Whatever Happened to the Mouse?: Since Family of Rogues, she hasn't appeared onscreen. Since Last Refuge, she seems to have fallen off the map entirely.
The New Rogues
- Aborted Arc: They were meant to be major recurring antagonists in Season 3 just like Cold's Rogues were in Season One, but the audience didn't warm to them so they've only had two appearances, unlike the old Rogues who had enough appearances that they were Barry's nemeses after Thawne.
- Big Bad Wannabe: They want to replace Cold's gang but are too smug to be successful at it even with their powers.
- A lot of their dialogue is similar to Snart's and Mick's exchanges from "Revenge of the Rogues".
- Also, the flashbacks of them trying to leave Snart's gang mirrors what Snart did in "Going Rogue", where he says "if you're out, you're out" before trying to kill the pair of them.
- Contrasting Sequel Antagonist: Unlike the old Rogues they have powers.
- Legacy Character: For the old Rogues since they've all left town.
- Remember the New Guy?: They never get any mention of being in Snart's gang prior to Season Three, despite being very prominent members that Snart had history with.
- Replacement Flat Character: Neither Scudder nor Dillion have much of a personality beyond being evil and wanting to steal stuff.
- Unholy Matrimony: A pair of metahuman criminals who are dating.
- Villain Team-Up: Unlike most metas they see the benefits in working together.
- What Happened to the Mouse?: They've been locked up in Iron Heights since Season 3 and haven't been seen since.
Sam Scudder / Mirror Master
Known Aliases: Mirror Master
Played By: Grey Damon
First Appearance: "The New Rogues" (The Flash 3x4)
Appearances: The Flash
A thief who used to work with Leonard Snart. They had a falling out just as the Particle Accelerator exploded. As a result he was trapped in mirror before he was finally released by some workmen. He has the powers to travel though any reflective surface.
- Adaptational Species Change: In the comics he wasn't a metahuman, he was just a thief who created technology to travel through mirrors.
- Adaptation Name Change: Played With. He and Evan McCullough both exist in the Arrowverse as the Mirror Master of their respective universes, but with their abilities swapped.
- Alliterative Name: His real name, Sam Scudder and nickname, Mirror Master.
- Always Someone Better: Despite what he thinks he's nowhere Snart's league.
- And I Must Scream: He was trapped in a mirror for three years before he was released.
- Back for the Dead: He returns in Season 7 where he is not only killed by Eva McCulloch, but she reveals that she was the first Mirror Clone she ever created. It's uncertain if the real Sam is even still alive or not, if he even existed post-Crisis.
- Badass in a Nice Suit: He's wearing a tux in his debut appearance.
- Beard of Evil: He's a villain sporting a beard.
- Beauty Is Bad: Caitlin calls him "good-looking for a criminal".
- Big Bad Wannabe: He wants to replace Snart as Central City's premiere super villain. However despite his abilities, he lacks Snart's tactical genius.
- Civvie Spandex: He wears a suit, rather than his trademark orange and green costume from the comics. Although it is mirror themed with certain reflective parts on the suit.
- Composite Character: He has the name of Sam Scudder, the first Mirror Master, but is a metahuman like the New 52 version of the character.
- Establishing Character Moment: His first minutes on screen show him spending his cut from a job on a fancy suit instead of waiting for the heat to die down, in direct contrast to the more methodical and coolheaded Snart.
- Evil Sounds Deep: He's a criminal with a fairly deep voice.
- Evil Versus Evil: He and Snart share a mutual dislike that morphed into hatred. Scudder tries to fight Snart once he gets out of the mirror, but he gives up when he finds out Snart left town.
- Flat Character: He doesn't have much characterization besides wanting revenge on Snart and robbing banks with Rosa.
- Narcissist: In the flashbacks, he spends his cut on a fancy new suit and spends ages admiring himself in the mirror.
- Make Way for the New Villains: In the first episode of season 7 the new Mirror Master reveals he was simply the first mirror clone she created and promptly kills him.
- Outlaw Couple: With the Top.
- Promoted to Love Interest: He's the Top's boyfriend where as in the comics the (male) Top was Golden Glider's lover.
- Reflective Teleportation: Scudder can teleport through reflective surface and trap people in reflective objects.
- Retcon: Season 7 retcons him into being another Mirror Clone created by Eva McCulloch. The fate of the real Scudder is unknown.
- Revenge: His original plan is to get revenge on Snart, but after learning that Snart is no longer around, he drops it rather easily.
- Sharp-Dressed Man: Mirror Master looks dapper in a dark suit.
- Small Name, Big Ego: He thinks without him and Rosa, Snart would be stuck robbing liquor stores.
- Smug Snake: Power or no powers, he's still not nearly as good as he think he is.
- Squishy Wizard: He can travel through and bring anything with him through any reflective surface, but take that away from him and there's not much he can do.
- Tall, Dark, and Snarky: He stands 6'2 and is definitely fond of shit-talking his adversaries.
- Weaponized Teleportation: He can send people through reflective surfaces that could end up with them plunging from a great height. He can also trap people in reflective surfaces.
Rosalind "Rosa" Dillion / The Top
Known Aliases: The Top
Played By: Ashley Rickards
Voiced By: María Fernanda Morales (Latin-American Spanish)
First Appearance: "The New Rogues" (The Flash 3x4)
Appearances: The Flash
Scudder's girlfriend and also a former associate of Snart's. The Particle Accelerator gave her the power to induce vertigo in people.
- Adaptation Dye-Job: The Top is brunette in the comics and most media. Here, she's blonde. Ironically, her actress is naturally a brunette.
- Appropriated Appellation: She takes a liking to being called "Top".
- Adaptational Name Change: Along with a Gender Flip, the Top goes from being named as Roscoe Dillon to Rosa Dillon.
- Adaptational Superpower Change: In the comics, the Top normally spins around in superhuman speeds, hence the namesakes. Here the Top can induce vertigo into anyone, causing them to disorientate and lose their balance. Played with as the comics' Top would go on to gain vertigo powers in later issues.
- Astonishingly Appropriate Appearance: She wears a yellow and green striped skirt which looks like a top when she's twirling around.
- Composite Character: This version of the Top's powers are more in line with Count Vertigo, who had a severe case of Adaptational Wimp over on Arrow and was reduced to a Non-Action Badass Normal.
- Eye Colour Change: Whenever she uses her powers, they glow green.
- Gender Flip: The Top is usually a male Roscoe Dillon, but here she is a woman.
- Girly Bruiser: She has no problem fighting in dresses.
- Hidden Depths: She was revealed to be the brains between her and Sam. Plus, since her time as a Meta (or perhaps just simply Post-Crisis), she has increased the potential of her powers to the point of mentally attacking other people.
- In Name Only: The only things she shares with her namesake are the last name, the alias, and being a member of the Rogues (well, New Rogues in this case).
- Kicking Ass in All Her Finery: In her debut episode, she's shown doing submission holds on her opponents while wearing formal gowns.
- Outlaw Couple: With Mirror Master.
- Obfuscating Stupidity: Revealed to be the case all along in Season 7. She blamed her crimes on Scudder while she was the brains the entire time.
- Pragmatic Adaptation: She doesn't spin, she just induces vertigo in people.
- Remember the New Guy?: Barry puts her on prison in the past, but it wasn't shown in the first two seasons. Justified as it happened as an effect of Barry "fixing" Flashpoint.
- Shadow Archetype: In season 7 it's revealed she originally had the same power set as Cecile but she figured out how to use them to hurt people.
- Squishy Wizard: She can induce vertigo in anyone, but she goes down as easy as any normal person.
- Took a Level in Badass: By season 7, her Meta powers are strong enough to deal psychic attacks to another person.
The Young Rogues
A duo of female criminals with meta-tech who decide to make their mark on Central City. Later they become a larger team led by Nora West-Allen and composed of even more criminals.
- Freudian Excuse: Just like the old Rogues:
- Joslyn grew up without her dad, because all he cared about was being criminal. And then her mom blamed her for Mark being deadbeat so she ran away when she turned 13 and her mom didn't care enough to find her.
- Peter grew up with an emotionally distant mother, which left him broken inside.
- Legacy Character: The second pair of criminals trying to take the old Rogues' place, they think if they can oust the Flash's identity they can become "legitimate Rogues".
Joslyn "Joss" Jackam / Weather Witch
Species: Human (Empowered via Metatech)
Played by: Reina Hardesty
First Appearance: "O Come, All Ye Thankful" (The Flash 5x7)
Appearances: The Flash | Crisis on Infinite Earthsnote
The estranged daughter of Mark Mardon.
- Age Lift: Her counterpart in the comics died as a very young child, and for that matter was born later in Mark Mardon's life.
- Adaptational Species Change: A metahuman in the comics, uses a meta-tech staff in the show. Which is an inverse of what happened with her father.
- Ambiguously Gay: It's not stated but she showed signs of attraction to both Silver Ghost and Nora, while showing contempt at best towards the men she's interacted with
- Antagonistic Offspring: One of her primary goals is to commit Patricide on Mark Mardon. This antagonism later almost became positive as she didn't want to continue down her father's criminal path, then enter Nora West-Allen and Raya Van Zandt and she later decides she's rather satisfied being a criminal.
- Bastard Bastard: She was conceived out of wedlock and abandoned by her father in favor of his criminal activities.
- Beam-O-War: Goes into one with the Flash, both using lightnings. She loses.
- Chronic Backstabbing Disorder: Towards Nora and Raya despite not seeming to get much out of at least the former betrayal.
- Composite Character: She's an amalgam of Joshua "Josh" Jackam and the Weather Witch, a minor copycat villain.
- Evil Is Hammy: Much like her dad, she is really overdramatic.
- Evil Versus Evil: She is trying to go after her father, who is an unrepentant criminal.
- Eviler than Thou: To Silver Ghost. She left her behind in Bolivia and possibly killed her.
- Foil: Presented as one to Nora West-Allen. Both have dads that disappeared and who their abilities are based after. Nora was temporarily upset at Barry like she was upset at Mark. Not to mention, both Nora and Joss were upset because their fathers chose their jobs over them. They also both have a past of running away, have resented their mothers, and have both been manipulated by an implied female love interest.
- To Axel Walker. Axel has a criminal Disappeared Dad he idolized regardless and became a criminal to impress him and break him out of prison. Joslyn became a criminal despite hating her criminal Disappeared Dad, looking like she wanted to break him out of prison at first but she really wanted to kill him.
- Gender Flip: In the comics, Mark Mardon had a son.
- Heel–Face Door-Slam: She is initially remorseful, but Nora adamantly refuses to believe her. When she is released against her will by Raya, Nora arrests her and makes it look like she deliberately escaped. This leads her to willingly join Raya.
- Heel Realization: A few weeks in prison made her realize she was just as bad as the dad she hated
- Like Parent, Like Child: Even though she hates her dad, she too is willing to destroy an entire city all just to kill one person. It was also implied that Mark was a victim of the same kind of negligence that he would later thrust upon Joss.
- Mythology Gag: She uses a large wand to channel her powers much like the comic version of the Weather Wizard (who is a metahuman here).
- Parental Abandonment: A victim of this by Mark Mardon, the reason she hates him so much.
- Pet the Dog: She saves Nora from being run over by Raya after the former tries to reach out for her, hinting at a later chance of redemption.
- Race Lift: Josh Jackam was Caucasian and the comics' Weather Witch was a dark-skinned blonde of unspecified ethnicity; Joslyn is portrayed by an Asian-American actress.
- Redemption Rejection: Despite hints in her second appearance that she wasn't beyond redemption she eventually abandons the idea. She eventually leaves Silver Ghost in Bolivia for being "all talk" and wants to be a "legitimate Rogue".
- Reformed, but Rejected: She feels horrible about her actions after being stopped and tries to atone for them, but Nora's unwillingness to believe her eventually drives her into Raya Van Zandt's arms.
- Roaring Rampage of Revenge: Against her father for being a shitty parent, to the point where she is willing to destroy all of Central City.
- Rogues' Gallery Transplant: In-Universe. Her appearance in National City is the first sign that things are very different after Crisis.
- The Runaway: Ran away from her mom at 13, because she blamed her for Mark walking out on her.
- Teen Pregnancy: Stated to be the result of one, hence her surname.
- Took a Level in Jerkass: Seemed like she could've reformed when Cecile read her mind and she felt guilty about where her path was heading, then later in the episode she saves Nora's life. In her next appearance she betrays Nora when their plan is going smoothly and is revealed to have also betrayed Van Zandt who recruited and corrupted her into further villiany in the first place after she got out of prison.
- To the Pain: When the Flash refuses to let her kill her father, she goes out of her way to attack Central City specifically because in her words, it's the best way to hurt heroes like him.
Species: Human (Empowered via Metatech)
Played by: Gabrielle Walsh
First Appearance: "The Flash & The Furious" (The Flash 5x10)
Appearances: The Flash
A former member of the Air Force that was wrongly dishonourably discharged, with meta tech that can control any vehicle.
- Adaptational Name Change: From Raphael Van Zandt to Raya Van Zandt, to accomdate the Gender Flip.
- Alternate Self: Has one on Earth-666 who accidentally killed her boyfriend.
- Composite Character: Silver Ghost from the comics and Rush/Diego Zhao as the driver of the S.A.M. automobile.
- Evil Mentor: Towards Joss, manipulating her into embracing being a criminal.
- From Camouflage to Criminal: A tragic example. She was a proud member of the USAF until her officers there used her as a scapegoat to save their reputation. Her undeserved discharge tarnished Raya's own reputation, eventually causing her to snap.
- Gender Flip: The comics Silver Ghost was male.
- Put on a Bus to Hell: Weather Witch ditched her in the middle of nowhere sometime prior to "Gone Rogue".
- Role-Ending Misdemeanor: She was dishonorably discharged as a scapegoat despite being innocent. This leads to actually become evil.
- Rogues' Gallery Transplant: The original Silver Ghost was a Freedom Fighters villain pre-Crisis and a minor Justice League villain post-Crisis.
- Technopath: Can control any vehicle with her meta tech.
- Then Let Me Be Evil: Had a spotless military record until she was scapegoated to preserve their reputation and dishonorably discharged. Now she decides she might as well be the criminal they made her out to be.
- Uncertain Doom: It's not entirely clear under what circumstances Weather Witch left her behind in Bolivia or even if she's still alive.
Brie Larvan / The Bug-Eyed Bandit / Queen Bee
Known Aliases: The Bug-Eyed Bandit, Queen Bee
Played By: Emily Kinney
First Appearance: "All Star Team Up" (The Flash 1x18)
A former Mercury Labs scientist who also happens to be a "narcissistic tech wizard" and hacker who strikes Central City during Felicity and Ray's visit at S.T.A.R. Labs during The Flash Season 1. She later attacks Palmer tech at Star City.
- Adaptation Dye-Job: Changed from black-haired into blonde, among other things.
- Adaptation Name Change: To accommodate her Gender Flip.
- And Starring: While not given a "Special Guest Star" citation, she gets the "And" billing in the regular guest star lineup in The Flash (2014).
- Animal Motif: Insects. Bees to be more specific.
- Arch-Enemy: Felicity dubs her as her personal nemesis as she gave her a run for her money in hacking.
- Atrocious Alias: She understandably doesn't care for the moniker, "Bug-Eyed Bandit", which Cisco and Ray gave to her. She instead changes her codename to be "Queen Bee".
- Attack Drone: Her robotic bees.
- Bee Afraid: Killer Robot bees are her weapons.
- Bee-Bee Gun: Not a literal one, but the humanoid form of her robot bees can "shoot" parts of itself in a manner resembling this trope. She later does use a wrist-mounted version when she teams up with the Young Rogues that shoots robotic bees.
- Beehive Hairdo: Her hairstyle when she was introduced, to match her Animal Motif.
- The Bus Came Back: After Team Arrow sent her into a coma, she comes back to Central City three years later joining the Young Rogues.
- Brain/Computer Interface: When she reappears on Arrow, she's upgraded her robot bees to control them via neural implants, allowing her to no longer be confined to a Hacker Cave.
- Celebrity Paradox: Caitlin discusses watching The Walking Dead with Cisco. Her actress was a major character on that show for three and a half seasons.
- Combining Mecha: As of her second appearance, her robotic bees can now combine into a humanoid Killer Robot.
- Composite Character: She is mostly a Gender Flipped version of the comic Bug-Eyed Bandit, Bertram Larvan. However, she eventually starts taking more aspects from Queen Bee and eventually adopts said name.
- Cute Is Evil: She's a morally lacking scientist.
- Dueling Hackers: With Felicity in the climax of her debut episode.
- Evil Counterpart: Supposed to be this to Felicity Smoak. This even extends to meta with their actresses both being named Emily. note
- Evil Genius: Has a brilliant mind, but is a notorious criminal willing to murder.
- Evil Is Petty: Takes the time to mock Felicity about breaking off her much-publicized engagement to Oliver.
- Gender Flip: The male Bertram Larvan is changed into the female Brie Larvan.
- Heart Is an Awesome Power: You might think a swarm of robotic bees would be no match for the fastest man alive with accelerated healing. You'd be wrong.
- Hell-Bent for Leather: Her dress is done in a seductive black leather.
- Hidden Depths: Is apparently a fan of My Girl and threatens to reenact her favorite scene on Thea.
- Hoist by Her Own Petard: Is stung into a coma by her own robot bees in "Beacon of Hope" after Curtis reprograms them.
- Letter Motif: Notice how her name(s) and many tropes associated with her starts with the letter B? Explanation
- Letting Her Hair Down: She no longer sports the Beehive Hairdo that she has on her first appearance.
- Mad Scientist: Her robotic bees were originally supposed to be used for agricultural purposes. She decided to modify them as weapons.
- Meaningful Name: "Larvan" being a reference to insect larva.
- Mighty Glacier: Not her, but the humanoid combat form of her robotic bee swarm. It's not particularly agile, but impervious to Team Arrow's conventional weaponry and overpowers Oliver through sheer brute force. Then again, it gets taken out quite easily by Felicity shorting it out with a lamp.
- Mind-Control Device: She upgrades her bees by connecting them to Spencer Young's phone, which allows her to channel its Mind Manipulation through them and do things like put Cisco in a trance. This lines up with Queen Bee's mental powers in some continuities.
- Nanomachines: Upgrades her bees on Arrow to not only sting with lethal venom, but also burrow inside targets and release microscopic copies to replicate inside a person's body, as Oliver found out the hard way.
- Not-So-Harmless Villain: Proves to be a much more formidable foe to Team Arrow than Team Flash, having upgraded the capabilities and lethality of her robotic bees, using guns, and shedding her silly hairdo.
- Pungeon Master: Loves bee-based puns, and her appearance on the scene usually has everyone else doing it.
- Release Date Change: In-Universe, this is how Brie Larvan escapes imprisonment: by hacking prison records and commuting her sentence.
- She wants to kill the Mercury Labs scientists who were responsible for her being terminated: the scientists who blew the whistle on her and Dr. McGee who actually fired her and destroyed her research.
- After getting the schematics for Felicity's bio-chip, she chose to stay and try to kill Felicity, having recognized Felicity's code as the same kind used to defeat her in Central City, and was determined to get her back for sending her to prison.
- Robot Master: She builds and commands a highly advanced swarm of robotic bees.
- Role-Ending Misdemeanor: In-universe. She was fired from Mercury Labs after she participated in an unauthorized military application of her mechanical bee research program.
- Rogues' Gallery Transplant:
- Both In-Universe and out. In-Universe, she was a Villain of the Week on The Flash before showing up on Arrow. In the comics, she's originally an enemy of the Atom, though she did fight him when Ray crossed over last season.
- Even in her first appearance on The Flash, though, she was set up as an enemy of Felicity in particular, who happened to be visiting Central City at the time. So it was no real surprise when her next appearance was on Arrow.
- Squishy Wizard: She only has her robotic bees as Attack Drones to rely on in combat. Destroy them and she'll be easy to beat.
- Super-Powered Robot Meter Maids: The subject of her Start of Darkness. Her robot bees were originally meant for agriculture, but for whatever reason, she outfitted them with lethal doses of bee venom so they could be used as weapons.
- Supervillain Lair: Has one on The Flash, an abandoned greenhouse with a honeycombed style Hacker Cave.
- Synchronized Swarming: Can control her robotic bee swarm to unite into a single bee-themed humanoid robot, able to go toe-in-toe with Oliver Queen. Alternatively, the bees can morph together into an impassable barrier, or the image of their creator's face for communication purposes.
- Took a Level in Badass: She now goes out on the field unlike in her first appearance, and has also upgraded her robotic bees.
- Unexplained Recovery: Shows up three years after being sent into a coma in "Gone Rogue" having apparently woken up for her coma and her tumor problems resolved.
- You See, I'm Dying: She really needs Felicity's bio-chip because she has a tumor on her spine.
Red Death's Rogues
- Legacy Character: Several members took up the codenames of a previous villain mantle.
Ryan Wayne / Red Death
Known Aliases: Red Death
Played By: Javicia Leslie
First Appearance: "Wednesday Ever After" (The Flash 9x1)
Appearances: The Flash
The adopted daughter of Thomas and Martha Wayne from Earth-4125. When her adoptive parents were killed, Ryan became obsessed with stopping crime before it happened, and thus created a suit that allowed her to replicate the powers of her universe's Flash, using her artificial speed powers to kill criminals before they could go too far. This naturally brought her into conflict with the Flash, sparking a growing war between them that got out of hand, causing her to become stranded on Earth-Prime.
- Adaptation Deviation: The Red Death's origin differs greatly from her comic counterpart, who is a Batman who forcibly fused with his universe's Flash. Ryan however gains her powers via a suit capable of creating an artificial Speed Force and it is implied that the Flash of her universe is still alive.
- Adaptational Distillation: The complex Dark Multiverse storyline with Red Death being one of many versions of evil Batmen is dropped for the show. Instead, this gets simplified to an alternate member of the Batfamily who happened to gain Super-Speed.
- Adaptational Wimp: The Red Death is a universal level threat in the comics and had helped the Dark God Barbatos in destroying several universes. Here, Red Death, while still dangerous, is easily defeated by Batwoman and Flash. She is also missing a few abilities from the comics such as creating energy contracts and aging people with her corrupted Speed Force.
- Arc Villain: The main antagonist for the first five episodes of season 9.
- Arch-Enemy: According to Red Death, her goal is to stop her timeline's version of Barry Allen from devastating her world. In reality, they are enemies because he's trying to stop her murderous rampage of killing criminals before they can commit crimes.
- Clothes Make the Superman: Rather than subject herself to the corrupting influence of the Negative Speed Force, she instead used it to power her armor.
- Composite Character: The Red Death of the comics was a version of Bruce Wayne from the Dark Multiverse who gained Flash's powers after fusing with him in the Speed Force. The Arrowverse version combines the characters of Red Death with Batwoman, due to being the resident Batman stand-in, where she is a version of Batwoman who manages to become a speedster.
- Empowered Badass Normal: She's as skilled and experienced as her counterpart, even before copying her Flash's speed. Also deconstructed as, during her Motive Rant, she claims she became a speedster because she came to realize that a "mere" Badass Normal was ultimately pointless in a world with metahumans and an endless supply of supervillains.
- Evil Cannot Comprehend Good: The Red Death is unable to comprehend how monstrous her murderous plans are to others, and believes that the Flash and his allies are too weak to do what she believes needs to be done rather than realize how immoral blatant murder is (especially if it is done to someone who hasn't even thought of doing a crime yet).
- Evil Doppelgänger: She's Ryan Wilder but from an "alternate timeline" (though from the way she describes it sounds more like another Earth).
- Evil Plan: Her initial plan was to force Barry to power a Cosmic Treadmill she created in order to return to her home, as it could only be powered by natural Speed Force energy instead of her artificial Speed Force. Following this plan's failure, she instead sought to cover the world with psychic projections of herself that are just as real and lethal as she is in order to eliminate all crime before it can even begin.
- Gender Flip: The Red Death of the comics was a Fusion Dance between two males. This version is a female.
- Genius Bruiser: In contrast to the Ryan Wilder of Earth-Prime, this version is not just a costumed vigilante but a Gadgeteer Genius whose skills possibly even surpass Luke Fox, being able to design her own artificial speed force as well as a remote controlled armor, among many other inventions.
- Hard Light: Like most speedsters, she is capable of creating solid lightning constructs, including ones shaped like batarangs and a grappling hook for her to swing on.
- Just Think of the Potential!: She claims that when being a Badass Normal wasn't enough, she copied her Flash's speed to turn Gotham City into a crime-free haven under the belief that he was not doing enough with his powers.
- Knight Templar: A very ruthless, villainous one who believes criminals should be hunted down and killed, before they even commit any crimes.
- Large Ham: She is quite theatrical with her villainy, prone to monologuing and pronouncements.
- Never My Fault: As far as she is concerned, the fault in her plans to pre-emptively kill criminals was that she didn't kill her world's Flash first.
- Nice Job Fixing It, Villain: If she hadn't changed her deal with Mark and simply given him what he wanted, he wouldn't have stuck around long enough to have a Heel–Face Turn and free Barry from the Cosmic Treadmill, thus ruining her plans.
- Pre Crime Arrest: A more lethal take on this trope, as her turn to villainy was marked by her willingness to kill criminals before they could even think about committing a crime. She intended to do the same in the present via lethal psychic projections of herself.
- Psychopathic Womanchild: She looks intimidating and scary at first, but when things don't go her way, she starts acting like a child throwing a tantrum.
- Red Is Violent: The moniker "Red Death" pretty much says it all—she wears red-coloured armor, and is a psychotic Knight Templar whose bloodthirsty personality matches her bloodthirsty plans.
- Remote Body: Red Death can control her suit remotely to act as a stand-in.
- Samus Is a Girl: In-Universe. When Barry first meets her, he assumes Red Death to be male due to the masculine build of her suit and her distorted voice.
- Secret Identity Vocal Shift: Her suit has a voice modulator inside the mask that alters her voice to sound deep and menacing.
- Shock and Awe: As a speedster, Red Death has control over lightning.
- Super-Speed: The newest speedster to menace the heroes.
- Well-Intentioned Extremist: A very deluded one, but she genuinely believes her actions are justice and to make the world better.
- We Used to Be Friends: Before going off the deep end, she was best friends with her world's Iris West. Unfortunately, she accidentally killed her world's Iris during one of her fights with the Flash.
- Villainous Breakdown: After her Cosmic Treadmill gets destroyed, she starts to lose her shit at the realization that she has lost her only means of returning home. Then in the episode following this, as her plans are utterly ruined, she becomes a screaming madwoman as the Flash and his team of Rogues, along with Batwoman, manage to defeat her, causing her to scream her head off in rage before being knocked unconscious.
Owen Mercer / Captain Boomerang II
Known Aliases: Captain Boomerang
Played By: Richard Harmon
First Appearance: "Wednesday Ever After" (The Flash 9x1)
Appearances: The Flash
A supervillain who makes use of high-tech boomerangs to commit crimes. He is revealed to be working with Red Death.
- Adaptational Wimp: Lacks the super-speed his comic self had.
- Ambiguously Related: It's never clear if he's still the son of Digger Harkness or not.
- Battle Boomerang: Makes use of these much like the original Captain Boomerang. Unlike Digger Harkness, he utilizes high-tech boomerangs that allow him to go up against the Flash.
- Big, Stupid Doodoo-Head: He tends to call everyone "dumbass", like he does to the Flash.
- Composite Character: His costume and gear are based off Harkness's comic outfit rather than Owen Mercer's comic costume.
- Legacy Character: To Digger Harkness, the original Captain Boomerang.
- The One Guy: Prior to Chillblaine allying with them, he was the only male member of Red Death's Rogues.
- Punch-Clock Villain: Owen has a very laid-back attitude and seems to not really care whether or not Red Death actually succeeds in her plans.
- Superior Successor: Downplayed. The original Captain Boomerang was an extremely skilled Badass Normal who used traditional boomerangs and was a One-Man Army who gave Team Arrow a lot of trouble, but ultimately was no match for the Flash. This one makes use of high-tech boomerangs and can fight someone of the Flash's caliber.
- The Team Normal: The only member of Red Death's Rogues without any superpowers, instead being a Badass Normal who relies on his high-tech boomerangs.
- Trick Arrow: Or rather Trick Boomerangs, which all have various functions including: exploding, force field generation, and even teleportation.
- Truer to the Text: Compared to Digger Harkness, this Captain Boomerang is a lot more faithful to the comics by donning the comics outfit, being an enemy of the Flash instead of Green Arrow, and using trick boomerangs instead of normal ones.
- Unrelated in the Adaptation: Comics Owen Mercer is the son of Digger Harkness and Meloni Thawne, making him half-brothers with Bart Allen. However, as Meloni Thawne does not exist and Bart is simply Barry and Iris's kid, Owen is not a Thawne in this universe.
- Villain Respect: Compliments Goldface for being able to deflect all of his boomerangs using only a gold chain.

Michelle Amar / Murmur II
Known Aliases: Murmur
Played by: Alexandria Wailes
First Appearance: "Rogues of War" (The Flash 9x3)
Appearances: The Flash
A deaf former EMT turned serial killer.
- Adaptational Job Change: She was a medical student rather than a full doctor.
- Ambiguously Related: It's unclear if she's related to Arrow's Murmer, Michael Amar.

- Malevolent Masked Woman: Wears a creepy mask as part of her supervillain identity.
- No-Sell: She is completely immune to Pied Piper’s sonic blast, seemingly absorbing it into herself.
- The Stoic: In contrast to her associates, she does not talk much, and with her face covered in a creepy mask, she does not show much emotion.
- Truer to the Text: As a former medical associate turned masked serial killer, she bears a closer resemblance to the comics than the previous version.
- The Voiceless: She does not speak due to being deaf, instead communicating via sign language.
- We Can Rule Together: Invites Pied Piper to join their side, but when he declines she goes right back to trying to kill him.
- Color Motif: Each of them follow a color motif based on their powers. Pied Piper is green, Goldface is gold, Hotness is red, Chillblaine is blue.
- Elemental Powers: Hotness is fire due to his Playing with Fire powers, Chillblaine is ice due to his Freeze Ray gauntlets, Goldface is earth due to his Extra-ore-dinary power over gold, and Pied Piper is air due to his sonic gauntlets firing vibrations.
- Enemy Mine: All of them were enemies of Barry/The Flash at one point, but now they have allied with him against a greater evil.
- Good Counterpart: To Red Death's Rogues, being assembled by Barry to go up against a common enemy.
- Noble Demon: Barry specifically selects the most moral members of his Rogues to be recruited.

Known Aliases: Pied Piper
Played By: Andy Mientus
First Appearance: "The Sound and the Fury" (The Flash 1x11)
Appearances: The Flash
The disowned son of a wealthy industrial family, former scientist at S.T.A.R. Labs and protégé of Eobard Thawne until he was fired and lost his hearing due to the Particle Accelerator explosion.
- Adaptation Dye-Job: Comic Hartley is either a blonde or a redhead Depending on the Artist, but here he's a brunette.
- Adaptation Personality Change: In the comics, Piper was, at worst, a Well-Intentioned Extremist, often shown to give most of his share of the takings from the Rogues' crimes away to various charities. He was also a passionate socialist and detested the sort of snobbery this version displayed towards Cisco, having rebelled against it for most of his life. Most striking, though, is that this version of Piper suffers from Lack of Empathy where the original was, if anything, often too nice for his own good. After Barry time-travels, he becomes one of Team Flash's friends, similar to him helping the Flash out in the comics. Post-Crisis first undoes this but then reverts back after they help him.
- Adaptational Superpower Change: In the comics he was a capable of creating Magic Music that hypnotises people. Here he fires off sonic blasts and has Super-Senses.
- Adaptational Villainy:
- His original counterpart was the Token Good Teammate in his villainous time. Here, he is outright evil and just becomes good because of Barry's time travel.
- Subverted Post-Crisis where while he has redemption undone, he (at least mostly) reforms and assists Barry as an ally to his team.
- Adaptation Relationship Overhaul: His comics counterpart is one of Wally West's best friends. They haven't even met yet in the Arrowverse.
- Alliterative Name: Starts calling himself the Pied Piper.
- Aloof Ally: Before the Particle Accelerator exploded, none of his colleagues like him. After Barry's third Cosmic Retcon, however, he was steered into the right path. Still, he becomes the external member of the team, which limits his physical interactions with them.
- Batman Gambit: A favorite of his. Out-gambits pretty much the entire Team Flash in his debut episode. And in the following one, he plays Cisco and manages to escape... but not before he helps lead Cisco to learn the truth about Ronnie Raymond.
- Black Cloak: Part of his supervillain outfit.
- Blessed with Suck: The particle accelerator explosion gave him superhuman hearing, but this made him extremely sensitive to sounds which caused him excruciating pain. However, he still manages to use his powers in just the right moments to help either himself or Team Flash.
- Brains and Bondage: He alludes to being into bondage, mostly as a form of sarcasm at least.
- Broken Ace: A brilliant mind, but he's had little in the way of emotional security for a long time: his wealthy parents disowned him for his sexuality, then he was essentially the protege of Eobard Thawne who booted him out when he discovered the high probability of the Particle Accelerator malfunctioning, and to top it all off his hearing was damaged by the explosion. Anti-social jerk that he is, it's hard not to pity him given his potential that he's now channeling for destructive purposes.
- The Bus Came Back: He returns from a four season long absence in "Grodd Friended Me", robbing a jewelry store and one of the Flash's regular enemies.
- Chekhov's Gunman: He's mentioned in "Revenge of the Rogues" but first appears in "The Sound and the Fury."
- Chess Motifs: He used to play chess against Thawne. After becoming a villain he continues using chess metaphors, such as calling Thawne's press conference about the Particle Accelerator "a pathetic bishop sacrifice".
- The Chessmaster: In his debut episode he's several steps ahead, engineering his capture in order to gain information on how to kill Barry, and nearly succeeding in doing so.
- Cosmic Retcon:
- Cunning Linguist: In addition to his native English, he speaks fluent Spanish, Japanese, French and Latin. According to Cisco, he knows at least one more language.
- Deal with the Devil: Offers one to Cisco at the end of "The Sound and The Fury": if freed, he will reveal where Ronnie is and help turn him back to normal. He succeeds.
- Decomposite Character: In the comics Hartley, not Cisco, is the Flash's tech-savvy best friend, and a Canon Foreigner supplants him as the lover of Barry's superior officer.
- Demoted to Extra: He was one of the main characters of the modern age pre-Flashpoint Flash comics, but he's only appeared in two episodes as of halfway through Season 4. He becomes a reoccurring character after his return in Season 6, but is still far from being a main cast member.
- Emerald Power: The lights on his stunners glow green.
- Empowered Badass Normal: Initially he Fights Like a Normal as his metahuman power (superhuman hearing) doesn't really help him in combat. What makes him dangerous is that he's a chessmaster with killer sonic technology who was almost able to kill Barry. As of Post-Crisis, he can now produce sonic blasts on his own with his sonic gloves merely being his Emergency Weapon.
- Everyone Has Standards: While being a major dick back in the day, he drew the line at letting the particle accelerator run when there was a great risk it could explode and kill innocent people.
- Expy: With the change of his weapon to gloves, he actually bears quite a resemblance to Shriek from Batman Beyond; especially because, just like Shriek, Rathaway gets severe auditory problems because of an accident, unlike the comics where he's deaf since birth.
- Face–Heel Turn: In his backstory. Sure, he was a jerk, but he still tried to warn Thawne that the Particle Accelerator had a severe chance of blowing up. Of course, Thawne already knew and fired him. Then his hearing became too sensitive after the explosion and went off the deep end.
- The Friend Nobody Likes: Was once this to everyone at S.T.A.R Labs because, as Cisco puts it, "mostly, he was a jerk. But sometimes... he could be a dick".
- The Glasses Gotta Go: He no longer uses glasses as of 2020 in the post-Crisis timeline.
- Good Is Not Nice: He was a major dick back in the day, but he was determined to stop the accelerator because he had figured out it could blow and he was entirely unwilling to let that happen. "Wells" fired him and coerced him into staying silent. Of course, he also provided information on Ronnie Raymond and Firestorm.
- Guest-Star Party Member: All his times aiding Team Flash tend to be one-offs every other season.
- Handicapped Badass: Suffered major damage to his ears and requires special hearing aid, but is still a genius and a competent fighter.
- Happy Ending Override: His reconciliation with Team Flash and his family is undone after the multiverse is recreated in Crisis.
- Heel–Face Return: From Barry's point of view at the end of Flash Back and the viewers, his alteration to the timeline has a now good and friendly Hartley save him from the Speed Wraith.
- Heel–Face Revolving Door: Initially just an unfriendly member of the S.T.A.R. Labs team, he turns into a villain after the particle accelerator explosion. Barry changing the timeline causes him to reconcile with the team, but Crisis undoes that, but then he reconciles with the team again after they save his boyfriend.
- Heel–Face Turn: Due to Barry's messing with the past, he has become a friend to Team Flash, or at least since Thawne is gone.
- He Knows Too Much: Thawne fired Hartley because he found out about "a chance" that the accelerator would explode, and threatened to ruin his credibility if he exposed this fact for good measure.
- Ignored Expert: Knowledge on the particle accelerator's failure that led to his getting sacked by "Wells".
- I Have No Son!: His estranged father's reaction when Hartley tries to contact him. Turns out he was disowned for being gay (as Caitlin puts it "old money, old values"). Something he was not happy about. After Barry changed the past during his debut, they've started reconnecting with him.
- In the Hood: As part of his supervillain outfit.
- Insufferable Genius: He makes Eobard Thawne look humble in comparison.
- I Surrender, Suckers: Twice. The first time he gets captured on purpose in order to steal all of S.T.A.R Labs' data regarding Barry. The second time, he allows Barry to disarm him, so that the failsafe in his gauntlets would activate and melt Barry's brain. (He even calls Barry out on falling for it twice)
- Jerkass: Comes off at this at his worst, ESPECIALLY during his debut episode. As Cisco explains, "Mostly, he was a jerk, but sometimes... he could be a dick."
- Jerk with a Heart of Gold: As much of a Jerkass as Hartley may be, he still cared enough to try and fix the Particle Accelerator and was unwilling to risk the lives of everyone in the building and possibly the city and was perfectly willing to admit to the public that there was a mistake. Unfortunately, he got worse after the accident... On the other hand, he also led Cisco to learn of Ronnie Raymond's whereabouts.
- Lack of Empathy: Subverted. As aloof and rude as he is, Hartley does have a conscience. When he overhears Barry's With Great Power Comes Great Responsibility speech before taking on Godspeed, Hartley gets overcome with guilt and finally decides to assist his former foe.
- Leatherman: He tells Barry that being captured by a guy wearing leather is a long time fantasy of his. This is partly him messing around and trying to make the others feel uncomfortable.
- Manipulative Bastard: He's pretty good at this, as proven by how he convinced Cisco to let him out of his cell.
- Movie Superheroes Wear Black: His attire is fully black with the only green found on his weaponized gloves (which are also mainly black). In the comics, at least the cloak is usually green.
- My Greatest Failure: He caused his boyfriend Roderick Smith to enter in a critical situation by putting him in a life of crime.
- Nerd Glasses: Wears a pair. Not that it makes him any less of a badass.
- No Social Skills: Thawne states that, in exchange for being brilliant, he has no skills with people.
- Not So Above It All: Mocks Cisco for liking Star Wars, but in Flash Back he makes a Harry Potter reference.
- Number Two: He was Eobard's deputy and protégé prior to him being fired after discovering that the Particle Accelerator was flawed.
- Pragmatic Adaptation: Playing a pipe like in the comics would have been nifty, but it's not a practical thing to convey so the change in his manner of weaponry does make sense in that regard.
- Punny Name: Rathaway sounds so suspicious for a guy whose Code Name is the Pied Piper.
- A Pupil of Mine Until He Turned to Evil: A former colleague of Thawne until Thawne fired and threatened him to keep him from telling the press about the Particle Accelerator. Barry messing with the timeline causes him to pull a Heel–Face Turn by the time of Season 2. Thawne on the other hand, is acknowledged to have suffered the same fate.
- Reformed Criminal:
- One of the positive effects of Barry messing with the timeline. Since Barry arrived during his and Hartley's first encounter (which has the latter attacking his parents' company), his criminal past sticks. Still, Hartley has pulled a Heel–Face Turn by the time Barry returns.
- Post-Crisis had him being bitter at Barry for putting his boyfriend in a coma, but he pulls a Heel–Face Turn after assisting the Flash and later makes amends when they restore his partner.
- Revenge: Hartley's goal is to make "Wells" pay for betraying him and ruining his career to conceal that the particle accelerator had a "flaw".
- Rival Turned Evil: He and Cisco started as a typical Sitcom Arch-Nemesis, but him becoming a criminal just made their already sour relationship much worse.
- Sensory Overload: He has the metahuman power of superhuman hearing, but his sensitivity to sounds causes him pain and facilitates the need of hearing aids to reduce the auditory input.
- Sixth Ranger: Barry messing with the timeline has made him into an ally of Team Flash by Season Two. History repeats with his post-Crisis self coming around in season 6.
- Slobs vs. Snobs: His conflict with Cisco. Hartley couldn't believe someone like Cisco could be a mechanical genius. This is, notably, a complete divergence from his comics portrayal.
- Smart People Know Latin: He and "Wells" would often converse in Latin.
- Sonic Stunner: His weapon of choice.
- Spanner in the Works: Surprisingly, gets incredibly close to being one to Thawne. He tries to fix the Particle Accelerator. Had he succeeded, Thawne's plan to create the Flash would've failed. His failed attack on Thawne's also reignited Joe's suspicions about the man, as Thawne's claims and the evidence didn't quite match up.
- Straight Gay: Aside from a brief moment where he taunts Barry, he comes off as this.
- Sudden Sequel Heel Syndrome: Post-Crisis, he's remained a villain which Flash was unaware of until confronting him.
- Super-Senses: Possesses superhuman hearing as the result of the particle accelerator explosion.
- Technobabble: Even more prone to this than Cisco or Wells.
- Took a Level in Badass: His meta powers post-Crisis are far more potent than before, even allowing him to fly with sound.
- Took a Level in Jerkass: Goes from obnoxious (yet considerate enough to try to fix the Accelerator) genius to terrorist and would-be murderer.
- Took a Level in Kindness:
- After the past was altered and he helped Team Flash with the Speed Wraith, he is friendly with them all...except for the deceased Thawne.
- Post-Crisis after his first redemption was undone, he manages to pull another Heel–Face Turn and once again becomes an ally for Team Flash.
- Tricked-Out Gloves: His gauntlets allow him to fire sonic blasts as dangerous attacks.
- Troll: When being captured by the Flash, he takes the opportunity to troll the Flash about his costume and Caitlin about losing her fiance to the accident.
- Villain Has a Point: His motive is to get revenge on Thawne due to being betrayed by him, but Thawne makes everyone think that it was due to his obstinate personality. In truth, Hartley was callously fired by his father figure for even knowing about the chance that the accelerator would explode, also threatening him to ruin his credibility so that he would never get any other job.
- Villains Never Lie: He did keep his end of the bargain with Cisco, before kicking him to the ground.
- We Used to Be Friends: In Pre-Crisis timeline, he was an ally to Team Flash, but his reconciliation with the team was undone after the multiverse was recreated in Crisis. They reconcile later.
- "Well Done, Son" Guy: Since he was disowned from his parents, Thawne became a father figure to him.
- What Happened to the Mouse?: He disappears after assisting to deal with the Time Wraith. A season 3 episode reveals he's still difficult to work with, suggesting his coming to help was a one-time thing. He eventually returns post-crisis, their relationship initially undone.
- Would Hit a Girl: Slaps Caitlin so hard he knocks her out.
Played By: Max Adler

- The Bus Came Back: A one-shot character from Season Four, who returned in Season Eight with a Heel–Face Turn.

- Evil Is Hammy: He's much more flamboyant than his predecessor Eric Frye.
- From Nobody to Nightmare: From a victim during Eric Frye's heist to a empowered bank robber himself.

- Heel–Face Turn: His love for his son convinces him to turn over a new leaf.
- Noble Demon: Has transitioned to this after Season 8, with Barry trusting him enough to recruit him for his services.

- Suspiciously Similar Substitute: He's basically an evil poor man's Firestorm, even propelling himself into the air using fire streams from his hands.
- With Great Power Comes Great Insanity: He was just a normal citizen prior to gaining powers, but afterwards he's a cackling maniac who's hellbent on causing chaos and robbing banks.
