- Adaptation Origin Connection:
- The Accelerator explosion that granted them their powers, when most of them have origins completely unrelated to each other (or the Flash). "Power Outage" sees Thawne namedrop other victims of the explosion that are established characters in the comics that, again, are completely unrelated otherwise.
- Later seasons follow with new means of gaining powers, but otherwise are still linked such as the Philosopher's Stone or the Dark Matter Bus Metas.
- All There in the Manual: More information about metahumans is divulged in two spinoff media:
- The Chronicles of Cisco, a blog which is basically a budding encyclopedia filled with details about criminal metahumans (and even the ones who don't have super powers, like Cold and the Bug-Eyed Bandit). Several entries also include some misadventures Cisco (and sometimes Caitlin) would have just taking care of them.
- The Flash: Season Zero, a digital tie-in comic which introduces a few new metahumans which have yet to appear on the show.
- Go-Karting with Bowser: The Chronicles of Cisco details Cisco partaking in "Movie Night" with the Pipeline's denizens.
- Informed Ability: According to Cisco and Julian, all metahumans (or at least those affected by the Particle Accelerator explosion) have a Healing Factor. This even becomes a plot point in The Flash Season 3 when Caitlin is gravely injured. In order to save Caitlin's life, her Power Nullifier was removed which directly results to her full transform as Killer Frost. However, only speedsters have demonstrated this ability until that moment.
- Informed Attribute: In Season 2, according to the Earth-2 Wells, there are far more metahumans than what we've seen so or that's been implied thanks to the Flash being a deterrent against the more malicious ones acting out in the open. We've yet to see this come to fruition as the following seasons see Team Flash dealing with metahumans unrelated to the Particle Accelerator Explosion.
- Inhumanable Alien Rights:
- In Season One, the criminal ones didn't get a trial, they were just sent to the Pipeline when Barry caught them; it's somewhat justified since Iron Heights (or any normal prison) isn't exactly equipped to handle them and they are all guilty of numerous crimes — mainly violent ones. At least until the Particle Accelerator goes back online and they all escape during a botched transfer to Lian Yu.
- Averted in Season Two, now that Iron Heights has been modified to contain them.
- In-Series Nickname: Everyone except Clyde Mardon and Griffin Grey got one courtesy of Cisco.
- Karmic Transformation: They get their superpowers related to something that they are in contact with (or close to, anyway) during the Accelerator explosion. Like the Mardon brothers flying their plane during a storm, Black conducting his stem cell research, Nimbus is in a gas chamber, etc. That said, we still have no idea how some of them (Bivolo, Baez, Bates, Simmons) got their respective powers.
- Mass Super-Empowering Event: There have been several events that have given rise to multiple metahumans.
- The first and largest event was the Particle Accelerator Explosion during December 2013. The majority of the Season One metas and a few from later seasons got their powers from this source.
- There was also a similar Particle Accelerator Explosion on Earth-2, which Zoom's metahumans originate from.
- Season Three has metahumans being created through the Philosopher's Stone thanks to the work of Alchemy/Savitar, which was capable of restoring powers to those who had them in the Flashpoint timeline.
- Season Four had DeVoe orchestrating one of these. Manipulating Barry to be released from the Speed Force, opening a portal that released dark matter onto a bus of people.
- Monster of the Week: The majority of the evil ones are villains that are faced once or twice in the series. The most notable exceptions are The Reverse-Flash and Firestorm.
- Mutant: The metahumans have all been altered on a genetic level and the Arrowverse makes it a clear distinction that the metahumans are a different category from other people with powers.
- Pragmatic Adaptation: Since metahumans are a relatively new concept in this show, the Pipeline is placed underneath S.T.A.R. Labs instead of in Iron Heights. In Season Two, the prison is properly equipped with a Pipeline, although the first Pipeline is still functional.
- Rogues-Gallery Transplant: Quite a few of them aren't/weren't enemies of The Flash in the comics.
- Tailor-Made Prison: The Particle Accelerator, the one root of all their powers, is outfitted to become their prison. To avoid charges of illegal imprisonment, Cisco designed a power-dampening section in Iron Heights.
- Touched by Vorlons: Those empowered by the Thanagarean meteorite, particularly Vandal Savage, as well as both Hawkman and Hawkgirl and their Reincarnations.
- Trapped in Another World: Most of the metahumans from Earth-2 (Zoom was taken to the Speed Force by Time Wraiths, Black Siren and King Shark were incarcerated by A.R.G.U.S., and Dr. Light is currently a Fugitive).
- With Great Power Comes Great Insanity: With a handful of exceptions, most of the meta-humans went Ax-Crazy with their powers, causing chaos and destruction. A good chunk of them were criminals before they got their powers, though.
Particle Accelerator Explosion
Species: Enhanced Humannote
A "man on fire" who is rumored to be hiding under a bridge somewhere in the city. The military has some interest in him, he is startling similar to Ronnie Raymond, Caitlin's supposedly dead fiancé and he is in some way connected to Professor Martin Stein's research.
It is then revealed that he is in fact Ronnie, but also Professor Stein, as the two were fused thanks to the Particle Accelerator explosion. With Team Flash's help, Ronnie and Stein have both been separated and learned to re-fuse at will.
After the battle against the Reverse-Flash, a wormhole opens in the sky of Central City. While Barry is attempting to close it, a strong energy similar to the one they produce when Ronnie and Stein fuse and defuse is needed to complete the process. Because of this, they decided to perform a Heroic Sacrifice. Barry was ultimately able to save Stein but not Ronnie, who apparently dies.
- Adaptational Attractiveness: In the comics and other adaptations, Firestorm has a straight out Flaming Hair. Here, it only happens when he activates his powers, and even then, the Tall, Dark, and Handsome appearance of his host body remains visible.
- Adaptational Intelligence: Both of his components qualify. In the comics, Ronnie is Book Dumb, while here he's a world-class engineer. The already intelligent Prof. Stein has also been given knowledge on Time Travel in addition to physics and nuclear energy, both of which are his only expertise in the comics.
- Adaptational Wimp: In a way, since he wasn't able to even learn the molecular transmutation skill that his comic counterpart has.
- Adaptation Expansion: Not him/them, but rather his/their Chest Insignia. In the comics, it's simply just part of the costume. Here, it functions as a stabilizer for him/them during the Fusion Dance.
- Alphabetical Theme Naming: Ronnie and Prof. Stein's respective Love Interests are Caitlin Snow and Clarissa Stein.
- Big Damn Heroes:
- He shows up just in time to save the Flash from the Reverse-Flash in "The Man in the Yellow Suit".
- He performs another one by tag teaming with The Arrow to take down the Reverse-Flash in "Rogue Air".
- Performs their biggest one by stopping the Singularity, though a sacrifice had to be made with Ronnie having been presumed deceased as only Dr. Stein came back out.
- Civvie Spandex: This version of Firestorm is not wearing a proper costume, and instead wears whatever clothes his host body is wearing.
- Comic-Book Movies Don't Use Codenames: Zigzagged. Though he at first identifies himself as "Firestorm", he was eventually revealed to have been referring to the F.I.R.E.S.T.O.R.M. project by Professor Stein. Once General Eiling starts pursuing him he's consistently referred to as Firestorm by Eiling and his people. Though they are actually talking about the matrix that caused Firestorm's powers, the man and the matrix are one and the same so in practice he does have a codename.
- Deus Exit Machina: Flash finally gets a metahuman on his side (that lasts longer than an episode, at least), but unfortunately, Firestorm has to go into hiding in another city.
- Double Consciousness: A literal example of this with two minds sharing the same body and taken to extremes when Stein and Ronnie were initially fighting each other for control, unable to separate their memories and desires.
- Fire-Forged Friends: Both literally and figuratively. The Flash himself counts as a figurative example.
- Flying Firepower: He can also fly.
- Fusion Dance: An unintentional one the night of the explosion. His components are Ronnie Raymond and Martin Stein. As of "Fallout", they can do this (as well as the reverse) willingly.
- Fun with Acronyms: Fusion Ignition Research Experiment and Science of Transmutation Originating RNA and Molecular structures. You really have to wonder how long it took him (and, by proxy, the show's writers) to come up with something that spelled out "Firestorm".
- Hand Blast: His primary means of attack and how he enables flight, aiming his hands downward enough force to defy gravity and allow for stable propulsion and gliding.
- Heroic Sacrifice: Performs one to close the wormhole atop Central City. Prof. Stein made it, but Ronnie apparently didn't.
- Heroic Suicide: Attempted when they hear Team Flash talking about him going nuclear and potentially destroying Central City. To be more specific, Stein thought of it while Ronnie protested given they're sharingbhis body, and the latter resented the former for a while because of this.
- Living MacGuffin: Team Flash want to help Ronnie, but Eiling's got his eyes on the Firestorm Matrix.
- Older Than They Look: While they're still Sharing a Body, Martin Stein tried introducing himself to an old colleague, who mistook "Ronnie" for a student in the college where he worked when Stein said "they went to school together".
- Playing with Fire: He's gained fire abilities since the explosion. He doesn't have much control over them, however. By the time his two components learned to fuse and defuse at will, they had the time to work on it.
- Prophet Eyes: Using his abilities makes his eyes turn completely white.
- Power Perversion Potential: When separated from their initial fusion, they can feel what the other is feeling. Now imagine if one or both of them are having an intimate time with their respective lady loves...
- Psychic Link: Due to being fused together in the Firestorm matrix, Ronnie and Stein both feel when the other is in great distress or pain.
- Together in Death: When they performed a Heroic Sacrifice to close the wormhole that is about to engulf Central City, though only Ronnie (apparently) dies. Invoked during Stein's death, as Caitlin told him during his funeral to say hi to Ronnie for her.
- Trademark Favorite Food: Pizza. Ronnie always liked it, and once they became psychically linked, Professor Stein grew to love it too when he originally despised it.
- Walking Spoiler: Thanks to his identity not being revealed until the ninth episode (and The Stinger of the eighth episode), when he's introduced.
- Wreathed in Flames: When he first uses his powers on-screen. In fact, in general whenever he uses his powers.
Species: Enhanced Human
A criminal and bank-robber who gained the power to control the weather from the particle accelerator explosion.
- Adaptation Dye-Job: Blond hair instead of dark brown as in the comics.
- Adaptational Badass: Clyde Mardon doesn't have share his brother Mark's weather powers in the comics.
- Adaptational Villainy: Clyde isn't even a criminal in the comics (most of the time, anyway), let alone a budding supervillain.
- Ascended Extra: Not only does Clyde not have any powers whatsoever in the comics, he is always a victim of Death by Origin Story for his brother, the Weather Wizard. In this continuity, Clyde himself has weather powers and is the first villain to be faced by the Flash. While he does die at the end of his attempted attack on Central City and serve as the motivation for his brother's vengeance as the true Weather Wizard later on, it's undeniable that he had a rather larger role before that in this incarnation.
- Arch-Enemy: He and his brother are this to Joe.
- Bank Robbery: How he uses his powers. At first anyway, until Detective West accidentally convinces him to think big.
- Comic-Book Movies Don't Use Codenames: Unlike the other metahuman villains, Cisco never got to call him Weather Wizard. Just as well, considering that his brother Mark is the Weather Wizard in the comics and takes that name on the show.
- Composite Character: Took his brother Mark's role as the first Weather Wizard in all but name. Turns out this was just a Continuity Nod to the idea that originally he invented the wand; his brother was always the true Weather Wizard.
- Drunk on the Dark Side: All that power drives Clyde nuts.
- Due to the Dead: Cisco once visited Clyde's grave as a request from Mark.
- Evil Is Hammy: As he gets increasingly Drunk on the Dark Side, Clyde becomes progressively hammier.
- Foolish Sibling, Responsible Sibling: Clyde is the Foolish Sibling to Mark's Responsible Sibling. Clyde is reckless while Mark is more level-headed. This is even reflected in their powers; while Clyde was more uncontrolled and wild with his powers, Mark is more precise, being able to generate a ball of hail and single bolts of lightning while indoors.
- Glass Cannon: His offensive power with the weather is phenomenal but as soon as Barry cancels out his powers Detective West takes him out with two shots.
- A God Am I: He genuinely believes he's God. Though given the circumstances, you can't really blame him, since he survived a plane crash that destroyed his plane in an explosion, and subsequently developed Weather Manipulation, along with, until he meets the Flash, being the only metahuman he knows about. According to his talk of how he thought of the Flash as "like him", he seems to believe that metahumans in general are gods, having no other real explanation for them himself.
- Moveset Clone: He and his brother share the same Weather Manipulation powers.
- Mundane Utility: Of a sort. His Weather Manipulation powers are potentially godlike, and he admits as much himself, but he uses them to help him with a Bank Robbery. Detective West notes just how stupid this is.
- No One Could Survive That!: He is presumed dead when his plane is caught in the blast radius of the particle accelerator's explosion. No one believes Barry when he's the only one to claim Clyde is not only not dead, but can now control the weather.
- Peek-a-Bangs: His fringe sometimes covers the left side of his face.
- Siblings in Crime: With Mark.
- Smoke Out: His favorite way of escape; conjuring a thick fog that conceals the entire area.
- Starter Villain: He's the Flash's very first antagonist. And he's killed by Detective West.
- Tempting Fate: Bellows to the cops, "DO YOU THINK YOUR GUNS CAN STOP GOD?" Later gets shot and killed.
- Tornado Move: Able to stir up violent hurricanes around himself.
- Weather Manipulation: His main ability. He uses it for fogs to allow his escape, hurricanes to cover a bank robbery, and in his final move, Tornado Move.
- We Hardly Knew Ye: Gone after his first episode.
Species: Enhanced Human
A scientist who was studying stem cell cloning who gains the power to duplicate himself.
- Dark Is Evil: His costume is pure black.
- Defiant to the End: He rejects the Flash's Take My Hand gesture, and thus falls to his death.
- Demoted to Extra: Multiplex in the comics was the Arch-Enemy of Firestorm for a long time, whereas here he (apparently) dies in his first appearance.
- Disney Villain Death: Purposely falls to his death after his defeat.
- Expy: His backstory brings to mind Mr Freeze, of Batman fame. He was a scientist looking to cure his dying wife, but was stopped by his Corrupt Corporate Executive boss and given superpowers related to his field.
- Hive Mind: His clones operate with the Prime's control but if the Prime is incapacitated all of them are.
- Me's a Crowd: He can duplicate himself.
- One-Man Army: Literally.
- Revenge: His motivation to kill Simon Stagg is to avenge his wife's death because his research was stolen by Stagg and he couldn't clone the needed body parts to save her.
- Rogues-Gallery Transplant: His comic counterpart is normally a Firestorm villain.
- "Shaggy Dog" Story: Not only does he fail to get revenge and seemingly dies in the attempt, Stagg is later killed anyway by Wells.
- Tragic Villain: Given his motivation it's hard not to argue this point.
- We Hardly Knew Ye: Gone after his first episode.
Kyle Nimbus/The Mist
Species: Enhanced Human
A criminal who was supposed to be executed during the night of particle accelerator explosion. The explosion saved his life and because he was in a gas chamber, and gave him the power to change into a poisonous mist.
- And I Must Scream: Imprisoned - presumably forever - in a containment unit at S.T.A.R. Labs to prevent him from killing again.
- Bald of Evil: He's got zero hair on his head. He doesn't even have eyebrows. Also, he's evil. Many people to be executed have their face and body hair shaved off, though that's only if they're sentenced to the electric chair (to keep the electric current from catching their hair on fire.)
- Elemental Shapeshifter: Can transform into a poisonous gas.
- Evil vs. Evil: He doesn't seem to get along well with Mark Mardon/Weather Wizard.
- Even Evil Has Standards: Not him, but about him. Apparently Nimbus, formerly a hitman working for an Armenian crime family in Central City, was bad enough that his employers were willing to turn him over to the police. The family heads are among his first victims.
- Evil Is Petty: After being captured, he has trouble being fed because he keeps trying to kill Cisco, his jailer. This is why Cisco tries to feed him with a repurposed bug drone he got from Brie "Bug-Eyed Bandit" Larvan's stores to give him food, nicknamed "The Destroyer". The Mist destroys it, first by damaging it critically with his mist, then by stomping on it when Cisco comes over to repair it. All of this basically for no reason. See here.
- Evil Sounds Deep: With an odd manner of speech to boot.
- Intangible Man: He's able to easily transform into smoke in order to avoid hits.
- Jerkass: Even apart from him being an assassin, Nimbus is a just plain unpleasant person.
- Logical Weakness: Since gas is the least stable form of matter, Kyle can't stay a gas long.
- Mythology Gag: His civilian name comes from the original Mist's son's name and one of Mist's alternate aliases.
- No Brows: He doesn't have eyebrows, ehich makes him creepier.
- Obviously Evil: If you saw this guy◊ walking at you, would "Villain" not scream in your head?
- Professional Killer: His old job.
- Punny Name: The guy whose Code Name is The Mist has Nimbus as his real surname.
- Revenge: His motivation is to kill everyone who put him in the gas chamber: the crime family who turned on him, the judge who sentenced him, and Joe the cop who arrested him.
- Rogues-Gallery Transplant: His comic counterpart is normally a Starman villain.
- Screw This, I'm Out of Here!: In "Rogue Air", he fights Barry for the second time and is quickly defeated due to Barry having learned how to create tornadoes by spinning his arms rapidly. Nimbus bails from the fight afterwards.
- Sealed Evil in a Can: At the end of his debut episode, he's put into a cell made up of the modified particle accelerator.
- Steven Ulysses Perhero: A nimbus is a type of cloud, his ability is... to turn into a mist cloud.
- Secret Keeper: Implied to be the only metahuman who knows that "Harrison Wells" is the Reverse-Flash.
- Super Smoke: Has the power to willingly turn into a cloud of poisonous gas and retain movement control.
- Villain Decay: Barry manages to fend him off easily in "Rogue Air." This is justified, though, as Barry had learned some new tricks since their last meeting (namely, the ability to create wind funnels).
- What Happened to the Mouse?: He hasn't been seen since he escaped in "Rogue Air".
Sergeant Bette Sans Souci/Plastique
Species: Enhanced Human
A former war veteran who was exposed to large amounts of shrapnel while she was trying to defuse a bomb. As she was being deported to Central City, the particle accelerator explosion instilled her with the ability to make things explode by touching them.
- Action Girl: She is a soldier, so that's a given.
- Adaptational Heroism: In the comics, Plastique was a villain of Captain Atom and a convicted terrorist before making a Heel–Face Turn. Bette here is portrayed as, at worst, an Anti-Villain who fears her powers and wants to get rid of them. The worst thing she does is attempt to kill General Eiling, a Knight Templar who would come after any and all meta-humans to turn them into weapons for the Army, and had to be convinced into doing so by Thawne.
- Astonishingly Appropriate Appearance: Kelly Frye really looks like the comic character◊.
- Bad Powers, Good People: She is a good person, but has very deadly powers.
- Blessed with Suck: Bette causes whatever she touches to blow up. Just so we're clear, she can't take the risk of touching anyone for the rest of her life.
- Career-Ending Injury: Her military career came into a scratching halt after a bombing accident in Afghanistan.
- Can't Have Sex, Ever: Bette can't even do slightly romantic things with any person, so it's safe to assume this.
- Continuity Cameo: Bette's only contact is listed as Cameron Scott, who is only mentioned by name. In the comics, Cameron Scott was Captain Atom, Plastique's husband.
- Decomposite Character: Her role as the Suicide Squad's Demolitions Expert is given to Shrapnel over on Arrow.
- Fiery Redhead: Literally speaking, anyway. Her temperament is more melancholic and phlegmatic.
- Good-Looking Privates: Her rank is actually (Army) Sergeant, but she is good-looking nonetheless and a Statuesque Stunner to boot.
- Having a Blast: Able to turn objects into explosive devices with a touch.
- Ironic Name: Her last name is a French phrase meaning 'without worry'. If anyone had reason to worry, it would be Bette!
- I Just Want to Be Normal: With her powers, it's not hard to see why.
- Military Superhero: Subverted. She's a former Army Sergeant and is the first good metahuman introduced after Barry (Cisco's powers are still sleeping when Team Flash meets her) but was killed before she even had a chance to become a hero like Barry.
- Mythology Gag: This wasn't the first time Plastique was killed by a former ally.
- No Body Left Behind: Her body exploded after her death.
- Purple Is Powerful: She wears a violet tanktop underneath her jacket, alluding to her comic counterpart's costume. Anything she touches also glows purple as a sign its about to explode.
- Race Lift: More of an ethnicity/nationality lift, but in the comics, Bette is a Francophone Quebecoise, whereas here she is an Anglophone American. Her last name is the same, though, strongly implying she is still of French ancestry.
- Rogues-Gallery Transplant: Plastique is normally a foe/love interest of Captain Atom.
- Statuesque Stunner: She's 5'8 and a very good looking woman. Cisco stops being angry with her for accidentally destroying Barry's suit when he sees her appearance.
- We Hardly Knew Ye: Probably the most high-profile minor character to get this so far, since viewers may remember her from Justice League Unlimited and Smallville. Gets shot by Eiling and her body blows up in her debut episode.
- Why Am I Ticking?: Though she wouldn't know, since she died beforehand. Her entire body turned explosive after she was killed and Barry had to take her out of the city and into the lake/ocean to contain the massive explosion.
Species: Enhanced Human note
Barry's childhood bully. After falling in a vat of molten metal, the particle accelerator gave him the power to turn his body into steel.
- Actor Allusion: Greg Finley playing a character who is in love with the female lead, and gets turned into a zombie seems awfully familiar.
- Age Lift: Traditionally, the Girder looks middle-aged. Here, he's in his mid-twenties. Also, he is a Wally West villain in most stories.
- Adaptational Attractiveness: Granted, Girder has a bulky figure, but he isn't particularly portrayed as handsome. The show's version of him is a Mr. Fanservice through and through.
- Alas, Poor Villain: He comes to such a pitiful end, used as a distraction by "Wells" and ending up slowly electrocuted until even his powers can't save him, that even his old victim Barry feels remorse for him and calls "Wells" out on it.
- Artificial Zombie: In Season 2, he is revived as a zombie through Speed Force lightning.
- Attention Whore: He attempts to cow Iris into writing a new blog all about him.
- Blood Knight: He was psyched upon realizing he'd actually get to fight the Flash, and when released by Wells, keeps his word and makes a bee-line for Blackout. He even says "I've never run from a fight." This gets him killed.
- The Bully: He was one to Barry when they were young, and he has not matured in the present day.
- Came Back Wrong: In his third appearance he's accidentally reanimated as a zombie. Barry decides to put him out of his misery so he can finally rest for good.
- Celebrity Paradox: Cisco directly calls him "iZombie". His actor played The Hero's Love Interest there during its second season.
- Chrome Champion: He can turn his body into steel.
- Comic-Book Movies Don't Use Codenames: Zig-zagged. Cisco builds a metal training dummy which he calls "Girder" so Barry can train to fight Woodward, who Cisco refers to as "your [Barry's] Girder". Unlike previous episodes he doesn't name the person directly. After his death, he is called Girder.
- Death Equals Redemption: He gives Barry one last warning to run before succumbing to his wounds from Blackout's attack.
- Hate Sink: He's a bully with no redeeming features. Averted in his second appearance.
- Jerk Jock: His whole personality. He does show one redeeming quality in his second appearance, when he tells Barry to run so he won't get killed by Blackout.
- Logical Weakness: His metallic body protects him from bullets, from punches, but not from electricity.
- Made of Diamond: The only way Barry was able to hurt him at all was by breaking the sound barrier.
- Nigh-Invulnerability: Thanks to his metallic body.
- Pet the Dog: After being gravely injured by Farooq/Blackout, he tells Barry to run for his life, when just a few days ago he was willing to kill Barry.
- Psychopathic Manchild: Downplayed, but present. He's a violent, selfish Jerkass who is not immune to temper tantrums.
- Rogues-Gallery Transplant: Played with. He is a Flash villain, but he's traditionally part of Wally West's Rogues Gallery in his tenure as The Flash. No longer the case in the reboot continuity where he becomes a Barry Allen villain.
- Schoolyard Bully All Grown Up: From what we see in Barry's flashback, Tony was every bit as nasty as a kid.
- She Is All Grown Up: Iris notes that he became attractive when he became an adult.
- Sleeves Are for Wimps: His shirt doesn't have any sleeves on it, typical of his Jerk Jock personality, and ideal to show off his shoulder tattoo and his powers.
- Super Strength: One of the powers he has.
- Villainous Crush: On Iris.
- Villainous Valor: Refuses to run from a fight. This gets him killed by Blackout.
Species: Enhanced Human
An adventurous young man who went to see the particle accelerator with his friends. Was sitting on the top of a power line the night of the particle accelerator, giving him the power to siphon electricity.
- Adaptational Villainy: In the comics, Farooq existed as a hero in the New Earth universe as part of Cyborg's team. Here he is portrayed as a Tragic Villain.
- Bald of Evil: Well, it really looks more as if his hair is shaved, but it gets the image and meaning across.
- Creepy Blue Eyes: Has a set of these.
- Excessive Evil Eyeshadow: Has black rings around his eyes that give this effect.
- Horror Hunger: Has to absorb electricity to "feed".
- Man of Kryptonite: His electricity absorption ability rendered Barry powerless for a while. And Thawne takes a sample out of Farooq's corpse to try to figure out why.
- Mana Drain: Basically what Blackout did to the Flash, completely draining off his power.
- Obviously Evil: Not to the extent of Kyle Nimbus, but Farooq has visible veins in his face, glowing eyes, and generally looks very creepy.
- Plasma Cannon: His electricity powers are high-end enough that his maximum lightning bolts can generate burning-hot plasma (which is what flash-fried his first victim). This is what allowed him to kill Girder when his earlier weaker bolts had no effect.
- Psycho Electro: The events that gave him his powers left him visibly mentally unstable, and with his electric-siphoning powers.
- Revenge: Obsessed with getting revenge on Thawne for the particle accelerator accident.
- Shock and Awe: He has the power to absorb and shoot electricity.
- Too Spicy for Yog-Sothoth: Dies from trying to drain too much of Barry's powers.
- Tragic Villain: Pre-explosion, he was just some happy-go-lucky guy who made the mistake of climbing an electric tower to see it. After being hit by lightning, he kills two of his friends via electrocution after they try to resuscitate him with CPR.
- We Hardly Knew Ye: Gone after his first episode.
Roy G. Bivolo/Rainbow Raider
Species: Enhanced Human
An artist turned bank robber, Roy has the power to induce a violent rage in people when he makes eye contact with them.
- Adaptation Name Change: Ultimately subverted. He initially goes by Prism instead of Chroma or Rainbow Raider, though Caitlin does suggest the latter name. It does eventually stick, even he says he likes it. In the comics, Prism is the alias of a different character.
- Alliterative Name: .As Rainbow Raider.
- Atrocious Alias: Turns out Bivolo actually prefers Rainbow Raider rather than Prism.
- Characters as Device: While he's the main threat of "Flash Vs. Arrow", ultimately his purpose was to give a reason for Flash and Arrow to fight, which was the real thing that sold the episode.
- Deadpan Snarker: He shows himself to be one in his second appearance in "Rogue Air".
Bivolo: Funny. I didn't get an itinerary.
- When Mardon asks him where they (the metahuman criminals) were being moved to.
- Later when Leonard Snart declares he freed them and waits for a "thank you", Bivolo halfheartedly thanks him with the same sarcastic tone.
- Dirty Coward: "Rogue Air" shows him to be one. While the other metahumans were engaging Team Flash, Bivolo is seen cowering in the truck avoiding the gun fire and lucks out when he sees Caitlin and whammies her. He later submits to Lisa Snart when she has her Gold Gun aimed at his head.
- Evil Is Hammy: Complete with the usual hammy theatrics that many supervillains hold. Cisco even lampshades how he's heard it all before.
- For the Evulz: He appears to get a kick out of filling victims with a Hate Plague, even when he it's not necessary for his goals to be carried out.
- Generic Doomsday Villain: No backstory or explanation of his motivation to being a villain is given. He just wants to rob banks and he happens to be a metahuman who likes causing havoc.
- Hate Plague: His main power. Bivolo uses color (by affecting a person's retinas) to mess with the part of the brain that governs executive functioning and cognitive processes such as impulse control. This induces a temporary psychosis in people which causes them to start acting wild and violently.
- In-Name-Only: His power is a fair bit different from his comics counterpart, whose main power was Hard Light constructs and using a variety of different light spectrums to induce varying emotions. His codename doesn't make much sense for the show's version given he only uses the red color.
- Meaningful Name: Roy G. Bivolo. Like the acronym for the rainbow?
- Mythology Gag: One name Caitlin suggests is the Rainbow Raider, like his first codename in the comics. Cisco immediately decrees that she is not allowed to choose the names ever again.
- No Eye in Magic: Requires eye contact for his powers to work.
- Non-Action Guy: He can't engage in combat himself, so he uses his Hate Plague powers to turn would-be enemies on each other.
- Offscreen Moment of Awesome: We never actually see him get taken down, and he just shows up in a cell in the pipeline.
- Red Eyes, Take Warning: When he's using his powers.
- Smug Snake: Just look at the confident smirk he wears when using his powers, then compare it to his ranting and raving when he's been locked away in the prison. He doesn't even get the dignity of being beaten on-screen.
- Amusingly, his pride is so strong that he even seems reluctant to thank Captain Cold for freeing him in "Rouge Air"
- Squishy Wizard: Bivolo's powers are the only thing that makes him a threat. Otherwise, he's a normal human, easily subdued when Barry and Oliver keep their heads about them.
- Strange Minds Think Alike: After hearing Snart's reasoning for why he shot Deathbolt in the face-"He owed me money"-Bivolo's expression suggests that he thinks that's pretty reasonable.
Species: Enhanced Human
A woman who can teleport anywhere she sees. She breaks her boyfriend out of prison and the two of them start robbing money trucks to pay off his debts to a local mobster.
- Adaptation Name Change: Is named Lashawn Baez in the comics.
- Adaptational Villainy: In the comics, she's a med student who only resorts to crime in order to steal a replacement heart for her father who was too far down the wait list. Otherwise, she's a good person, and even outright saved Linda Park's life. Here, she was already into crime before getting powers, and seems to outright enjoy beating up the Flash. That said, her motives are still somewhat sympathetic.
- Age Lift: She's about the same age as her comics counterpart, who is considerably younger than Barry, as she was a Wally West-era villain.
- And I Must Scream: How she describes her stint in the Pipeline:Do you have any idea what it's like to be stuck in that box!?
- The Bus Came Back: She returns two and a half years later as the Starter Villain of The Flash Season 4 after last appearing in the penultimate episode of the very first season.
- Dark Action Girl: She's able to give Barry a run for his money with a combination of her powers and some single stick-esque moves.
- Driven to Villainy: The crimes she committed are to help the love of her life (spiriting him away from prison, and then stealing money so that he can pay the mob boss off his back). When the mob boss sees her with her powers, he immediately seizes an opportunity to keep using her to do his dirty work. In the end, she willingly surrenders to the Flash not just because of her Kryptonite Factor, but because her lover ditched her when he knew she's going to lose.
- Food as Bribe: According to Cisco's tie-in blog, he got her to look out for him while he installed viewing screens in the cells of the more dangerous metahumans by agreeing to mix peanut M&M's into her popcorn.
- Go Mad from the Isolation: She's very furious for being kept at the pipeline for months.
- Had to Come to Prison to Be a Crook: Previous to acquiring her powers, Shawna was just a petty thief, and in her introductory episode she came out as sympathetic; however, after spending several months in the metahuman prison, she had become considerably bitter and more aggressive.
- Improbable Weapon User: She uses a pocket spyglass in order to increase the effectiveness of her teleportation, and also to beat people around with.
- Logical Weakness: She can teleport to anywhere she can see, which means her powers are useless if there isn't any light around.
- Love Makes You Evil: Shawna despite starting as a petty crook, just wants to leave Central City. Her lover keeps convincing her to commit crimes - first to pay a debt and later just to become rich. When he abandons her, she gives up.
- Rogues-Gallery Transplant: Like Girder, is an enemy of the third Flash, Wally West, not Barry Allen.
- Screw This, I'm Out of Here!: Opts to not fight the heroes with the escaping Metahumans and instead teleports out of their while she has a chance.
- The Smurfette Principle: The only female villainous metahuman as of the first season.
- Teleporters and Transporters: Can teleport as far as she can see. Also, unlike her comic book's counterpart, her power doesn't produce unwanted explosions when using it, making her a lot stealthier.
- Teleporter Accident: However she can still produce explosions, but only if she teleports incorrectly. Cisco developed a gun teleporter gun on the principle.
- Teleport Spam: Sometimes uses these in battle or in Season 4 to travel distances.
- Took a Level in Jerkass: She was easily one of the most sympathetic villains in the show, as she was just a thief that broke her boyfriend out of jail and seemed to have no interest in actually harming, much less killing people. When she escapes in episode 22, she flat-out tries to murder Caitlin for keeping her in a box for months, which is fair enough.
- Undying Loyalty: Shawna still loves her boyfriend even after he leaves her at the last minute.
- What Happened to the Mouse?: Hasn't been seen since she escaped "Rogue Air". She does come back in "Chronicles of Cisco" where she reveals she's no longer interested in normal humans and only dates metas, and returns properly in season 4.
Mark Mardon/Weather Wizard
Species: Enhanced Human
Clyde Mardon's older brother. He holds a grudge against Joe for shooting his brother.
- Adaptational Attractiveness: He is usually depicted as Lean and Mean, but here he's portrayed by the Tall, Dark, and Handsome Liam McIntyre, who previously headlined a show about gladiators note . Read: Gladiators.
- Adaptational Badass: Instead of his brother inventing a "weather wand", which is the source of his powers in the comics, in the show he's depicted as a metahuman. The weather wand makes it in, but is instead used to counteract his powers.
- Adaptation Dye-Job: His comic counterpart has black hair, but the show keeps his actor's dark brown hair.
- Alliterative Name: Mark Mardon. His Code Name, Weather Wizard, also counts.
- And Starring: Promoted to this citation in the Guest Stars lineup starting Season Two.
- Arch-Enemy: He and his brother are this to Joe. It gets more personal after Joe kills Clyde.
- Avenging the Villain: Came back to Central City to avenge Clyde's death.
- Awesome by Analysis: He's studied and tested his abilities rather than simply just taking them as is, and has been studying the Flash. If Captain Cold analyzed his cold gun to the tiniest detail, Mardon's done this with his powers.
- Badass Beard: Unlike his brother, he sports this.
- Battle in the Rain: He invokes this by bringing rainfalls most of the time he shows up. Doubles as Actor Allusion since his actor famously played a role whose Red Baron is "The Bringer of Rain".
- Beard of Evil: As a supervillain, he counts.
- Beauty Is Bad: Tall, dark and handsome, but a dangerous supervillain.
- Blow You Away: Unlike Clyde who prefers Tornado Move, Mark loves generating strong gusts of wind.
- Bond Villain Stupidity: Could have easily and quickly killed Barry when he held a large number of children captive by placing bombs in their Christmas presents and threatening to detonate them if Barry tried to escape or fight back, but instead toyed with Barry by using extremely painful but non-lethal attacks. This gave Team Flash enough time to find and neutralize the bombs. Once Barry learned this, Clyde got his ass thoroughly kicked.
- Chekhov M.I.A.: He went missing after the plane he and Clyde were hi-jacking during the Mass Super-Empowering Event crashed.
- Civvie Spandex: Wears a dark green jacket with lighter pockets and an upturned collar, echoing his comic version's second costume.
- Debt Detester: He broke Snart out of Iron Heights, just because he owed him and wanted to get it out of the way.
- Decomposite Character: In the comics, he is the sole Weather Wizard. However, his brother Clyde also filled that role as this series' Starter Villain.
- Evil Sounds Deep: Is evil and has a deep voice.
- Evil vs. Evil: He doesn't seem to get along well with Kyle Nimbus/Mist.
- Flight: By season two, he's worked out how to use his powers to fly.
- Foolish Sibling, Responsible Sibling: Mark is the Responsible Sibling to Clyde's Foolish Sibling. Clyde is reckless while Mark is the more level-headed sibling. This is even reflected in their powers; while Clyde was more uncontrolled and wild with his powers Mark is more precise, being able to generate a ball of hail and single bolts of lightning while indoors.
- Glass Cannon: Like his brother, his powers don't make him immune to bullets, but he's more clever about using his powers to take out anyone that may take a shot. When Barry travels back in time, he is caught off guard and captured with near comical ease.
- A God Am I: Much like his brother, though he's more subtle.
- Jerkass: Not counting his brother, Mardon is aggressive and confrontational with everyone he meets. In "Rogue Air", he tries to pick a fight with Nimbus just because, and just glares at Snart rather than thanking him for freeing him.
- Knight Templar Big Brother: He responds at Joe shooting his brother via Roaring Rampage of Revenge.
- Last-Name Basis: Team Flash mentions him as "Mardon", his nickname.
- Leitmotif: Epic as hell, extremely catchy, and a fan favorite.
- Moveset Clone: He and his brother share the same Weather Manipulation powers.
- Near Villain Victory: He nearly annihilated the entirety of Central City in his first attack had Barry not Time Travelled and reset the timeline.
- Never Found the Body: Clyde mentioned that he couldn't find him after their plane crashed during the Particle Accelerator incident.
- Not So Invincible After All: While dangerous, he's only a threat to Barry if he can take him completely by surprise, if he has other metahumans backing him up, or if he can force Barry to not go on the attack by threatening hostages. Without one of these to stack the deck in his favor, Barry takes him down easily every time.
- Person of Mass Destruction: The first metahuman to have the entire Central City at his mercy and is only stopped because Barry pushes the Reset Button via accidental Time Travel.
- Pragmatic Adaptation: In the comics, the Weather Wizard's powers came from a technological "wand" his brother Clyde invented, enabling weather manipulation. In the show, he's a metahuman.
- Promotion to Parent: Clyde mentioned (in a flashback) that Mark raised him since he was 10 years old.
- Real Men Wear Pink: He likes Mean Girls.
- Revenge Before Reason: He concedes that Clyde "was no saint," but still feels driven to avenge him.
- Roaring Rampage of Revenge: He's really, really upset at Joe for killing Clyde.
- Rogues-Gallery Transplant: In-universe. After the events of Season 1, he shows up on Vixen where he fights said titular hero, as well as the Flash and Firestorm.
- Shock and Awe: He loves striking his opponents with lightning bolts.
- Siblings in Crime: With Clyde.
- Tall, Dark, and Handsome: Lampshaded word-per-word by Shawna Baez.
- Tall, Dark, and Snarky: Stands 6'2 and is a very chilly person.
- Underestimating Badassery: Seems prone to this when it comes to anyone other than the Flash. He's fully aware that he needs to stack the deck in order to have a chance against Barry, but is pretty dismissive of both Captain Cold and the Trickster. He clearly doesn't like Snart, but also doesn't seem to realize that Snart's strategic planning abilities, tactical skills, cold gun, and ability to out-think his opponents would pretty much negate his weather powers. Hasn't bit him in the ass yet, but time will tell.
- Unexplained Recovery: While he did say that he received grave injuries, he didn't specified how he was nursed back to health.
- Weather Manipulation: His metahuman power. His methods of using it are different though, instead making localized storm clouds to attempt to strike his subjects with lightning, shooting water at them with his hands, creating hail to kill people, or a tidal wave.
- Would Hurt a Child: He allies with The Trickster to give children explosives disguised as Christmas' gifts.
- You Killed My Father: Joe killing his brother is his main reason for the Roaring Rampage of Revenge.
Species: Enhanced Human
A meta-human who has the ability to shape shift into any person he touches.
- Alas, Poor Villain: When asked who he really was, Hannibal transformed back into what appeared to be his Shapeshifter Default Form with a Bald of Evil and Eyeless Face along with pale skin and a distorted voice. When he did this, he embarrassingly replied, "I, uh, can't remember." However, his grin turns into a frown when he repeats saying it, in a "wait a second, I really can't" sort of tone. Not only that, he's later used as yet another of Thawne's pawns, posing as him as a patsy for the real Eobard.
- Appropriated Appellation: As Barry, he hears Caitlin's name for him. He likes it.
- Bald of Evil: Since he can't remember what he used to look like, his "true form"'s head is bare.
- Becoming the Mask: He's shape shifted into so many people he's forgotten his real identity.
- Body Double: For Thawne. It ends up getting Bates killed.
- Chekhov's Gunman: His name is included in Oliver Queen's hit-list.
- Curbstomp Battle: Everyman was the first time Barry really went to town on someone who wasn't a good guy. At first Hannibal landed some good ones by distracting Barry with some morphing into his friends. But eventually Everyman's taunting pissed Barry off and he found out that a low-end shapeshifter can't compare to a high-end speedster in a fistfight.
- Early-Bird Cameo: His name is seen on Oliver's List in season 1.
- Eyeless Face: His attempt to take on his original appearance results in one, as he can't remember it anymore.
- Facial Horror: The result of his forgetting his original appearance is not pretty.
- Frame-Up: His criminal M.O., by taking on the appearance of someone else to get through security and subsequently committing thefts.
- Minored in Ass-Kicking: For a guy whose schtick is changing faces, he's a really good fighter. He was able to escape Thawne, an accomplished boxer by kicking his ass. He also put up a decent fight against the Flash until Barry started using his superspeed.
- Noodle Incident: How Hannibal earned a place in Robert Queen's list is never elaborated on, and neither is how he ended up in Central City during the events of the Pilot.
- Power Copying: Averted. At first Team Flash were afraid he could do this as a side-effect of his shape-changing and so they recommended that Barry not go melee on him, handicapping Barry for the investigation in the process. Once they get some genetic material from Everyman, they find out that he can't copy Barry's power so it's okay for Barry to go for a dust-up.
- Rogues-Gallery Transplant:
- Played with In-Universe. His name can be seen in Oliver's hit-list during the pilot episode of Arrow, but Barry and his team are the ones who eventually fight him.
- Furthermore, Everyman has been an enemy to a lot of heroes, including Green Arrow and Black Canary, but has never been an enemy of the Flash.
- Sex Shifter: He can transform himself into a woman, a fact that he demonstrated in his debut episode.
- A Sinister Clue: His left-handedness was how Iris and Team Flash were able to tell he wasn't Barry, or that Eddie was framed for shooting two police officers.
- Shapeshifter Guilt Trip: He tries doing this to Barry in their fight. But by the time he takes the form of Eddie, the guy he framed for murder, Barry hits his Rage Breaking Point and punches him across the room.
- Shapeshifter Identity Crisis: After being captured, he changes back into his real form, but he has no idea who he was. Worse still, he doesn't want to because whoever he was is traumatic for some unknown reason. When Cisco attempted to show him pictures of himself from his grandmother's house he refused to look and asked for them to be taken away.
- Shapeshifting: His primary ability.
- Shapeshifting Seducer: He kisses Caitlin while disguised as Barry.
- Shout-Out: A killer named Bates who impersonates his mother and lies to the authorities, where has anyone heard this before?
- Shout-Out Theme Naming: His name comes from two iconic cinematic Serial Killers; Hannibal Lecter (The Silence of the Lambs) and Norman Bates (Psycho). Barry Lampshades why anyone would name their kid Hannibal in this day and age.
- This Was His True Form: He returns to his initial appearance after being killed.
- The Unreveal: Why exactly is he on Oliver Queen's hit-list was not brought-up in his debut episode, which ironically also featured an important Crossover to Starling City. Considering he dies in his second appearance we're unlikely to find out too.
- Weak, but Skilled: His powers aren't as offensively or defensively powerful as the other metahumans we've seen but his clever use of them, psychological warfare and skills in hand to hand combat make him a big threat to Barry and his friends.
- What Did You Expect When You Named It ____?: Honestly, naming your kid "Hannibal" is practically begging for him to become a criminal.
- White Shirt of Death: Played with. He was shot while impersonating Eobard Thawne, who was wearing an all black outfit. Once he dies, though, he reverts to his original form who was wearing a white polo.
- Win Your Freedom: Everyman gets his freedom after Thawne releases him to deal with Cisco. Hannibal doesn't get to enjoy his freedom for long, he ends up getting gunned down by Joe.
- Would Hit a Girl: Not him specifically. But he invokes this trope when he takes the form of women in Barry's life, only for the Flash to continue attacking him/her. He mockingly ask the Flash if this was how he treated all the women he knew.
- Wrong Genre Savvy: After disguising himself as Barry and learning that he and Caitlin are part of a crime fighting team, he assumes they're the eventual Official Couple who are currently in the UST stage.
Jeremy Tell/Double Down
Species: Enhanced Human
A meta-human who gained his ability due to being tattooed at the time of the particle accelerator explosion in Central City. His ability allows him to peel the card tattoos off of his skin and use them as lethal weapons.
- Alliterative Name: Double Down.
- Death Dealer: His cards are generated by his body and they are lethal.
- Glass Cannon: He can generate a seemingly endless supply of cards, and has great aim, but beyond that, he's just an ordinary human. A Groin Attack from Felicity stalls him, punches from Diggle knock him out, and a bullet to the shoulder hurts him like it would anyone else.
- Just for Pun: Indulges in one or two game-based puns. He avoids being a Pungeon Master by not doing it that often, and avoiding card-based puns (he says "draw" instead of the more poker-appropriate "push," for instance).
- Only in It for the Money: He's a killer for hire, not a HIVE true believer or crazy madman like Anarky. When things get too weird/dangerous he pulls his Screw This, I'm Out of Here!.
- Power Tattoo: His powers are based on his tattoos because he was getting one with the explosion hit.
- Rogues-Gallery Transplant: Double Down is a Flash villain in the comics. Though he ends up in Iron Heights afterwards.
- Screw This, I'm Out of Here!: When he sees that Damien is a sorcerer, he tries to nope out of the city. Though he is stopped by Diggle and Green Arrow.
- Small Role, Big Impact: Appears as a typical Villain of the Week, but completely compromised the second Team Arrow base in his debut episode.
- Tattooed Crook
Russell Glosson/The Turtle
A thief who has the ability to absorb the kinetic energy of everyone around him, thus making everyone move slower than him.
- Action Survivor: He mainly uses his powers and guns to defend himself. Without them, he's helpless.
- Adaptational Attractiveness: Downplayed. While he didn't get a dramatic makeover, he still appears a lot more pleasant compared to his comic counterpart.
- Adaptational Badass: Played with, the original comics' Turtle was an unpowered criminal mastermind with no physical ability, and his successor Turtle Man was more of a gag villain for the Flash to take on in his very first issue. This one's superpowers are actually very effective against the Flash, and are thought to be key against Zoom, but the character himself is just a petty thief who got lucky with his powers.
- Adaptational Villainy: The comic book version of the Turtle, while a villain, was basically just a petty thief who would rob banks. This one is a Yandere psychopath who murdered his own ex-wife and steals what is most precious to other people out of spite.
- Asshole Victim: What he did to his ex-wife and tried to do to Patty mean that few tears were shed over his death. The only reason anyone feels bad about is because Harry is a good person who's torn up by taking a life at all, and because Jesse is horrified to learn that her father killed someone.
- Collector of the Strange: He steals rare artifacts and brings them back to his hideout to decorate it. He also has his ex-wife's corpse on display.
- Composite Character: Of the Golden Age Turtle, with the powers of the Silver Age character Turtle Man.
- Dead Guy on Display: He has his ex-wife's body in a display case at his hideout and intended to do the same to Patty before the Flash interfered.
- Early-Bird Cameo: Inverted. In the comics, he is the Starter Villain for Barry. Here, he's introduced a year and a half after Barry first became The Flash.
- Fat Bastard: He's slightly overweight and is a psychopath.
- Foil: He is the Antithesis to Barry and Zoom in that both of them are Speedsters while he slows everything down, in fact Earth 2 Dr. Wells forcibly and lethally extracted his DNA in an effort to stop and kill Zoom
- Freudian Excuse: He was upset because his wife tried to leave him. After he was affected by the particle accelerator explosion, he used his new powers to force her to stay. Then he started stealing things people valued the most, and keep them as trophies in his wife's old workplace.
- If I Can't Have You...: Killed his ex-wife and keeps her on display when she refused to go back with him.
- In the Hood: He wears a green hood that symbolizes a turtle's color.
- Killed Off for Real: Harry kills him at the end of the episode.
- Laser-Guided Karma: Keeps his dead ex-wife on a museum display stand and plans on doing it to Patty as well. He ends up imprisoned in the Pipeline, which more or less looks like one. The Irony is lampshaded by Team Flash.
- Playing with Syringes: How he dies. Dr. Wells requires Turtle's slowing time abilities, so the good doctor jams a syringe up his nose to extract the power, resulting in Turtle's death.
- Remember the New Guy?: Played for Laughs, Cisco and nearly everyone on Team Flash treat him like Cisco's Arch-Enemy and a threat they all know about and have discussed, while Barry doesn't even know about him.
- Small Role, Big Impact: He dies at the end of his introduction episode after Harry fatally takes parts of him to study on how steal The Flash's speed, which he successfully managed to.
- The Social Darwinist: Downplayed. In his conversation with Patty, he says it's a waste of time to save people since they'll only take life for granted in the end. Which is why he views the Flash's heroics as pathetic.
- Squishy Wizard: He's only untouchable because of his power. Without it, he's easy to beat by any opponent with proper skills or/and powers.
- Stalker with a Crush: It is heavily implied that he was this to his ex-wife.
- The Stoic: He doesn't show much emotion.
- Time Stands Still: Gives off this impression to people around him when he uses his powers, although all he does is slowing them down by absorbing their kinetic energy.
- Unknown Rival: Comes in both ways, both also Played for Laughs. Cisco and the rest of Team Flash sans Barry himself is dead set on capturing him. As stated before, both Barry and Glosson themselves are unaware of each other until they start crossing paths.
- Wax Museum Morgue: He keeps his dead ex-wife's corpse in a museum display stand and plans on doing the same to Patty had Barry not intervened.
- Yandere: He couldn't bear the idea of leaving his wife, so he killed her and kept her corpse in a display case to admire forever.
Species: Enhanced Human
A man thrown into a tar pit during the night the particle accelerator exploded. He returns after two years to exact revenge on the people who nearly killed him.
- Adaptational Angst Upgrade: The comics Tar Pit was a lazy criminal who liked his new form; here, he suffers from a case of Being Tortured Makes You Evil.
- Age Lift: He's traditionally a Wally West villain. Here, he's in the same age range as Barry and instead got his powers during the latter's tenure as the Flash.
- And I Must Scream: He was stuck in the pit for two years before the Central City government got around to cleaning up the plant and broke through the hardened asphalt that kept him trapped.
- Being Tortured Makes You Evil: The Body Horror below and the following two years he spends to recover are what drives his Unstoppable Rage.
- Blob Monster: He turns into tar.
- Body Horror: He describes in excruciating detail how his flesh was burning when he was thrown into the tar pit.
- Clipped-Wing Angel: His golem mode is impressive but is easily taken out with Cisco's tech.
- Humanoid Abomination: Even when he's in his human form, you can tell that there's something wrong with him. The Undeathly Pallor, the Black Eyes of Evil, and the tar seeping from his very being are hints that he's trying to look human, but only enough to vaguely pass through a crowd.
- Magma Man: Well, tar, but the principle is the same.
- Mighty Glacier: He has a "golem mode" where he becomes stronger and more durable, but at the expense of his mobility.
- Not Quite Dead: He should've died when he was thrown into the tar pit, but the particle accelerator explosion mutated him.
- Roaring Rampage of Revenge: His only goal is to hunt the people who threw him into the pit, collateral damage be damned.
- Rogues-Gallery Transplant: He is a Wally West villain.
- The Unfettered: He doesn't care about the people who will get caught in his Revenge.
Species: Enhanced Human
A metahuman with Super Strength, but also accelerated aging, who mistakes "Harry" Wells as his false earth-1 counterpart.
- Adaptational Early Appearance: In the comics, he is an acquaintance of Bart Allen aka Impulse aka Kid Flash II aka The Flash IV, who is Barry's grandson.
- Adapted Out: His energy manipulation powers, which is his power in the comics, is not present.
- Age Lift: Played with. He is currently 18 years old but got his powers at 16, which is part of the age group he belongs to in the comics. However, he's around that age during a much earlier point in time of his existence in the comics (see Adaptational Early Appearance above).
- Alas, Poor Villain: All he desired was a cure for his mutation, but he dies from his own powers.
- Alliterative Name: Griffin Grey.
- Anti-Villain: One of the least malicious metahumans seen on The Flash thus far. While he does kidnap Harry, it's only because he mistakes him for Earth-1's Harrison Wells and wants him to cure his Rapid Aging. And while he does eventually decide to murder Harry, it's only after it becomes clear that his mutation can't be undone and he crosses the Despair Event Horizon.
- Bald of Evil: When he's aged into an old man, he loses his hair at the same rate he loses his mind.
- Blessed with Suck: His powers in a nutshell - his cells have mutated to the point that he has Super Strength but due to oxidative stress his proteins are being destroyed causing Rapid Aging the longer he uses his powers.
- Car Fu: Throws a car at Joe.
- Despair Event Horizon: When Wells is unable to give him a cure, Griffin loses all hope and takes his anger out on the Flash.
- Diabolus ex Machina: Shows up and kidnaps Harry at a time when Barry has lost his speed and Caitlin is in Zoom's hands.
- Driven to Villainy: He abducts Dr. Wells in the hopes of finding a cure for his condition, but when the doctor is unable to comply he passes the Despair Event Horizon.
- Dying as Yourself: He reverts back to his true form after death.
- Emo Teen: He is an 18 year old young man stricken with Rapid Aging. He is taking it in a way that you expect.
- Hidden Depths: He had studied a lot on chemistry in attempt to reverse his condition, thus he knew Harry was stalling for time when his cure was simply diluting a chemical over and over.
- I Just Want to Be Normal: His main goal is to be cured of his powers.
- Pedestrian Crushes Car: Stops Harry's van in a Hancock/Luke Cage-esqueway.
- Rapid Aging: A side effect of The Particle Accelerator explosion is that when he uses his enhanced strength his bodies proteins and DNA get oxidated causing him to age rapidly, the more strength he uses the faster it happens.
- "The Reason You Suck" Speech: He gives a very poinent one to Harry (whom he mistakes for "Harrison Wells") accusing him of not caring about the damage his particle accelerator has done or the lives he's ruined thanks to turning so many people into metahumans. While it was aimed for Earth-1 Wells it works in making Harry realise all the damage he's done on Earth-2 and resolve to atone for it.
- Right for the Wrong Reasons: Griffin's speech to Harry is quite accurate. He's just delivering it to the wrong Harrison Wells (who, ironically, actually is Harrison Wells, unlike the one that Griffin had a grievance with).
- Rogues-Gallery Transplant: In the comics, he is Bart Allen's Evil Former Friend.
- Self-Disposing Villain: Actually a plot point. Since Barry can't take Griffin down as he's lost his speed the plan is to use his own Rapid Aging against him and have him overexert himself so he becomes frail and weak.
- Smarter Than You Look: He quickly figures out that Wells was playing him while pretending to manufacture a cure for him.
- Super Reflexes: Dodges an energy blast from Harry's energy rifle when it was fired by Barry. Later blocks a bullet fired by Joe by lifting a nearby car.
- Super Strength: His power. Sadly it has a fatal drawback.
- This Was His True Form: In death he reverts back to his true age.
- Throw a Barrel at It: He chucks an Ace Chemicals barrel at Barry. Ups this with a car later
- Tragic Villain: He doesn't want to be the bad guy, but he'll do anything to gain a cure for his mutation.
- Two First Names: Per the DC Comics norm.
- Villain Has a Point: His "The Reason You Suck" Speech towards Wells is nearly true.
- Woobie, Destroyer of Worlds: All he desires is to prevent his rapid aging in order to resume his normal life, but he's Driven to Villainy.
- Younger Than They Look: Thanks to his Rapid Aging.
- Your Days Are Numbered: His powers end up shortening his lifespan until he dies.
Sam Scudder/Mirror Master
Species: Enhanced Human
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.
- Badass in a Nice Suit: He's wearing a tux in his debut appearance.
- Beard of Evil: He's a villain sporting a Badass 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 vs. 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.
- 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.
- 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
Species: Enhanced Human
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 Guy and a 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.
- 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.
- 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.
- Squishy Wizard: She can induce vertigo in anyone, but she goes down as easy as any normal person.
Species: Enhanced Human
- Achilles' Heel: A sonic dampener can negate his vertigo powers.
- Adaptational Species Change: In the comics, Discord was a Badass Normal who used sonic-tech, while here he's a metahuman.
- The Aggressive Drug Dealer: A drug dealer who is more than happy to get violent.
- Alliterative Name: Sean Sonus.
- And Your Little Dog, Too!: Kills Vincent Sobel, Dinah's partner and lover, just to spite Dinah.
- Arch-Enemy: To Dinah Drake, having killed her partner and lover, she dedicated the next three years to hunting him down.
- Character Death: Dinah kills him with a gunshot.
- Composite Character: He's closer to the comics Count Vertigo than Arrow's Count Vertigo himself, being a metahuman crime boss with the ability to induce Vertigo, as well as being an enemy of Black Canary and Green Arrow.
- Comic-Book Movies Don't Use Codenames: He's never referred to as "Discord", though Wild Dog does dub him "Dirtbag".
- Establishing Character Moment: His introduction shows just how much of a bastard he is, having Dinah tied to a chair all bloodied up from torture, before bringing in her partner Vincent and executed him in front of her.
- Evil Counterpart: To Dinah Drake. The night of the Particle Accelerator explosion, both he and Dinah were granted sonic based metahuman powers, only Dinah's used hers to fight crime while Sonus used his to further his own crime spree. In addition, both of their powers can be halted by a sonic dampener.
- Kick the Son of a Bitch: Dinah executes him with a gunshot. Considering what a horrible person Sonus is, who can blame her?
- Meaningful Name: Sonus sounds quite similar to sonar, which fits his sonic based powers.
- Not So Different: Yet another metahuman who can induce vertigo, after The Flash already had the Top.
- Would Hit a Girl: Has Dinah bound to a chair and quite evidently given her a beating. He very nearly tried to execute her too had he not been interrupted.
Species: Enhanced Human
A nefarious crime lord, with the ability to control and manipulate metal, who once had connection with Caitlin/Killer Frost.
- '90s Hair: Vibe / Cisco certainly thinks so.Vibe: Are you a time traveller? 'Cause those white-girl-dreads came straight from the Nineties!
- Adaptational Wimp: Carries around a bucket full of scrap metal and bolts to focus her powers. In contrast, her comics counterpart throws bridges at people, and eventually is made of iron.
- Affectionate Nickname: Dispenses these to her Mooks, colleagues and foes alike.
- Bad Guys Do the Dirty Work: In "Harry and the Harrisons" where she is recruited by Team Flash, they keep trying to stop her from killing any of the metas they go up against, including Norvok. She agrees, but for her trouble she still cuts out Norvok's eye tentacle.
- Big Bad Ensemble: While DeVoe is the Big Bad, Amunet constantly causes trouble Team Flash throughout the season and forcing them to detour from their main goal to deal with her.
- Card-Carrying Villain: Proudly admits she has no heart.
- Comic-Book Movies Don't Use Codenames: Her comics title of "Blacksmith" goes unused here.
- Drunk On The Darkside: She was once a stewardess in what she describes as an hard and abusive position. Once she gained powers she embraced them and gleefully turned to a life of crime.
- Early-Bird Cameo: Is mentioned a few times to Caitlin, before finally appearing in person.
- Elemental Baggage: She carries around a bucket of metal shillings to use her powers on.
- Enemy Mine: Team Flash are forced to recruit her in "Harry and the Harrisons" upon realizing she's the only one immune to DeVoe's powers.
- Evil Brit: Katee Sackhoff uses a British accent for the character.
- Faux Affably Evil: Plays up her charming personality, dishing out an Affectionate Nickname to everyone around her, but when cornered, drops the facade and reveals the demon underneath.
- From Nobody to Nightmare: Used to be a stewardess, and her first victims after gaining her powers were colleagues who sexually harassed her.
- A God Am I: Believes she and Killer Frost could be this if they joined forces.
- Hunter of His Own Kind: She traffics metahumans, and is a metahuman herself.
- Jerk with a Heart of Jerk: It at first seems that at the very least, Amunet follows all her deals through. In the case of Caitlin, however, she gave her a placebo and lied about it being a cure for her powers.
- Lesser of Two Evils: Alongside DeVoe, which is why Team Flash are forced to recruit her once they find out she's immune to his powers.
- Magnetism Manipulation: Has the ability to manipulate and weaponize metal.
- Ms. Fanservice: Wears tight dresses that reveal her cleavage. Being played by Katee Sackhoff certainly doesn't hurt.
- Nominal Hero: Recruited by Team Flash to fight DeVoe, the greater evil, but her hero qualities end there.
- Obviously Evil: It's quite easy to pick up she's not a nice person early on, with her style of clothes, her Creepy Shadowed Undereyes, and her pale complexion.
- Pet the Dog: She gives Caitlin a genuine motivational You Are Better Than You Think You Are speech so that she can operate on Dominic Lance.
- Power Fist: Her preferred use of her powers is to craft a makeshift giant metallic glove.
- Remember the New Guy?: She had no mention at all prior to Season Four, but Caitlin/Killer Frost was already well acquainted with her by the time of her debut.
- Selective Magnetism: As powerful as her abilities are, they can be negated in the face of an even stronger magnet. She also seems limited to a specific kind of alnico alloy.
- Slavery Is a Special Kind of Evil: Her treatment of the Weeper, chaining him up, leaving him emaciated and having him regularly beaten to produce his drug tears slightly unnerves even Killer Frost.
- Spanner in the Works: She and Warden Wolfe's scheme to sell off Barry and all the Bus Metas in True Colors turns out to be a major disruption in DeVoe's carefully laid plans.
- Unexplained Accent: Seems to have a Trans-Atlantic accent, which is (fittingly) entirely artificial. That, or it's either Sackhoff best attempt at British.
- Villainous Breakdown: Quickly drops her smugness when things don't go her way.
- We Will Meet Again: Threatens Caitlin/Killer Frost she will have her vengeance the next time they meet.
Species: Human note

- Brought Down to Normal: After Matthew Kim touches him and unwillingly transfers his powers to Jaco Birch.
- Evil Brit: Has a heavy british accent.
- Evil Is Burning Hot: A bank robber with fire based powers.
- Flat Character: Only has a very short amount of screentime, with the below mentioned Jaco Birch becoming a much greater threat with his powers.
- Playing with Fire: A methuman with pyrokinesis.
- Prophetic Names: A man named Eric Frye who has fire powers.
Philosopher's Stone Husks
Edward Clariss/The Rival
Species: Enhanced Human
An evil speedster in the Flashpoint timeline and Wally West's rival.
- Adaptation Distillation: His backstory from the comics is never brought up in the show. He's a Generic Doomsday Villain straight from the get-go, with no explanation on how he got his powers in the Flashpoint timeline.
- Adaptational Heroism: While he's still a violent criminal, most of his more heinous acts, such as killing 80 people to prove a point to Jay and prolonging Joan Garrick's cancer, are omitted.
- Adaptational Wimp: In the comics he was a dark mirror to Jay Garrick, and enough of a threat to be considered his Arch-Enemy. Here he's a goofy Villain of the Week who gets taken down by Barry in less than an episode at a time.
- Age Lift: In the comics, he is a contemporary of Jay Garrick. Here, he is instead part of Barry and Wally's generation.
- Asshole Victim: He's killed by Savitar for failing to kill the Flash. Would anyone really miss him?
- Ax-Crazy: He's obsessed with being a rival to Kid Flash and proving himself to be the best, all while having obvious emotional issues and a penchant for violence. Waking up in the post-Flashpoint timeline just makes it worse.
- Badass Boast: Half his dialogue is bragging about his abilities.
- Blood Knight: His defining trait is wishing to find someone worthy to be his rival.
- Bullying a Dragon: He refers to Alchemy as his "sidekick" despite it being painfully clear that the latter is the superior in their relationship.
- Catch-Phrase: "I have no rival."
- Chewing the Scenery: One of the most theatrical villains who indulges in comicbook levels of hamminess.
- Composite Character: His costume takes after the Black Racer and the Daniel West version of the Reverse-Flash.
- Dark Is Evil: Wears all black and is an Ax-Crazy Smug Super.
- Deal with the Devil: He teams up with Dr. Alchemy to kill the Flash in exchange for ultimate power.
- Death by Adaptation: The comic incarnation of the character eventually became an Energy Being after being trapped in the Speed Force. The Flashpoint timeline version doesn't live long enough to get that far, but Barry neutralizes that timeline, allowing Clariss a second chance at life. However, he's soon killed by Savitar for his incompetence.
- Decomposite Character: His initial role in the comics as an impostor of Jay Garrick's Flash was given to Hunter Zolomon/Zoom here.
- Demoted to Extra: In the comics, he is Jay Garrick's Reverse-Flash. In the Arrowverse, he is nothing more than a Villain of the Week and doesn't get the same Big Bad treatment that Eobard Thawne and Hunter Zolomon got.
- The Dragon: To Dr. Alchemy for a grand total of one episode.
- Evil Counterpart: Both he and Wally are young, untested speedsters mentored by an incarnation of the Flash (Prime Barry Allen for Wally and Dr. Alchemy/Savitar for Clariss). While Wally is an aspiring superhero, Clariss is a villain For the Evulz.
- Evil Is Hammy: He's not the least bit restrained in his actions or his dialogue, probably due to being Drunk on the Dark Side.
- Generic Doomsday Villain: He doesn't have much of a personality outside of being a self-absorbed psychopath who wants to kill every speedster.
- In-Name-Only: In the comics, Rival is supposed to be an imposter Jay Garrick, as well as said Flash's Arch-Enemy. Here he resembles the Black Racer, is an enemy for Wally West, and is a generic Villain of the Week.
- In Spite of a Nail: The post-Flashpoint version still ends up being a speedster wearing the exact same costume, justified due to the visions he receives of his other life.
- Killed Offscreen: He is murdered by Savitar in the closing minutes of "Paradox", but we don't see the full footage of his death until the end of the next episode.
- Not-So-Harmless Villain: He's probably one of the goofiest-looking villains to appear on the show yet, what with his goblin-esque mask and constant babbling about being a rival to Kid Flash. He's so non-threatening when compared to the likes of Zoom that it's almost laughable...until he manages to stab Kid Flash clean through the chest with a piece of rebar and create not one, but TWO cyclones that threaten to destroy Central City. Suddenly he's not so harmless anymore.
- Plot-Irrelevant Villain: In "Flashpoint" Clariss is not the main menace in contrast to another villains of the week. The real danger is in the time aberration created by Barry.
- Red and Black and Evil All Over: His costume is a ridiculous version of Zoom's costume with reddish-orange streaks and a goblin-shaped mask.
- The Rival: Literally to Wally, though he is "dissatisfied" with him. He considers Barry more of a Worthy Opponent.
- Took a Level in Badass: As another negative effect of Barry's Cosmic Retcon, Clariss not only remembers his life in "Flashpoint", but thanks to Dr. Alchemy's method of restoring his powers, he is able to truly rival Barry as a speedster.
- Rogues-Gallery Transplant: A villain for Wally West and Barry Allen instead of Jay Garrick, a change seemingly made to compensate for Hunter Zolomon becoming a Barry Allen and Jay Garrick villain.
- Secret Identity: Averted. He wears a mask but doesn't bother trying to keep his identity secret, in fact sometimes he'll tell people who didn't even ask.The Rival: I think rivals should know each other's names.
- Small Name, Big Ego: After getting his powers in the new timeline, Clariss sees himself as the next Reverse-Flash or Zoom, an evil speedster who can outpace the Flash. Barry takes him down without much trouble, and Clariss ends up being killed by Savitar. His condescension to Alchemy is another sign of his disproportionate ego.
- Smug Snake: He's so arrogant that he even calls Dr. Alchemy his "sidekick" in his rematch with Barry in the post-Flashpoint timeline, despite the fact that Alchemy was the one to give him back his powers in the first place.
- Smug Super: He doesn't hesitate to show off his speed and call himself the greatest speedster ever.
- Starter Villain: For The Flash Season Three.
- Suddenly SHOUTING!: Tends to do this when talking about how much of a "rival" he is to Kid Flash.Kid Flash: What have you got against my city?
The Rival: The city's just fine. It's the people in it that need to be educated... THAT I HAVE NO RIVAL!
- Super Speed: His powers are functionally identical to Barry's and Flashpoint Wally's, though he seems to be slightly faster than the latter.
- Tornado Move: He can produce tornadoes as a ranged attack using his Super Speed.
- Voice of the Legion: Like all speedsters, he can vibrate his vocal chords to disguise his voice. He does it even around people who've seen him unmasked.
- You Have Failed Me: Savitar doesn't let him live long after he fails to kill the Flash, brutally killing him in his prison cell.
Species: Enhanced Human
An abused foster child. She has a second, more aggressive personality named Magenta who can control metal.
- Abusive Parents: Well, foster parents. Frankie's foster father is physically and emotionally abusive.
- Age Lift: In the comics, she's Wally West's Psycho Ex-Girlfriend. Here, she's only a teen while Wally is a young-adult.
- Allergic to Evil: One of Magenta's goals. Even when she's in control, Frankie's presence is still under the surface subconsciously restraining her, and she wants Frankie gone as much as their foster father. Dr. Alchemy convinces her that the best way to do this is to do something so shockingly terrible that Frankie can't handle it and ceases to exist. Magenta opts to obliterate the hospital her foster father is in, and very nearly succeeds.
- Ax-Crazy: Magenta's number one solution to any problem is to kill it with as much overkill as possible. This is such a contrast to Nice Girl Frankie that none of the cast have any trouble buying the Jekyll & Hyde angle.
- Color Motif: As if it's not obvious enough with her name, her entire outfit contains different shades of violet.
- Extra-ore-dinary: She can control anything with a trace of metal in it, from a lamppost to a freaking tanker.
- Fighting from the Inside: Unconsciously. While Frankie has no idea what Magenta is doing, her presence still keeps Magenta from being as unrestrained as she wants to be. It becomes more literal during her confrontation with Barry in the episode's climax, as the two personalities furiously battle for control. Thanks to Barry's help, Frankie wins, seemingly banishing Magenta for good.
- Happily Adopted: Thanks to Team Flash, Frankie is headed to a home that is presumably this, with a Heel–Face Turn that will hopefully stick.
- Jekyll & Hyde: Frankie is submissive and afraid, but Magenta is all her anger given a mind of it's own.
- Laser-Guided Amnesia: Frankie has no idea what happens when Magenta took over, or even that Magenta exists, though she apparently had an idea something was off. Even when the danger passes and everything ends well, she can't remember any of it.
- Mood Ring Eyes: When Magenta takes control, her eyes turn neon violet. They seem to be related to her powers, as Frankie still has them when she finally takes control and undoes Magenta's actions in the end.
- Pint-Sized Powerhouse: Just a teenage girl, but a very powerful metahuman with magnetic powers who can cause immense destruction.
- Purple Is Powerful: Has a Purple Color Motif and can control metal.
- Roaring Rampage of Revenge: Her asshole foster dad may be overdue for some comeuppance, but dumping a ship on the hospital he's in is overkill. Alchemy's visions imply that in Flashpoint Magenta went on to continue this rampage throughout Central City.
- Split-Personality Takeover: What Magenta is trying to do to Frankie.
- Superpowered Evil Side: Played with a bit. Frankie is unaware she even has powers, but it appears that - like the comics - while Magenta is more associated with her powers both personalities do have access to them.
- Tragic Monster: Even without mentioning that Frankie has no control over her actions, Magenta herself is the product of what's implied to be a lifetime of traumatic experiences. Alchemy notes that in Flashpoint, where Magenta had free rein, she inflicted pain because that's all she knew.
- Two First Names: Per the DC Comics norm.
Species: Enhanced Human
A metahuman with the ability to become a huge living shadow.
- Adaptational Wimp: From an incredibly powerful immortal to a mere Villain of the Week.
- Casting a Shadow: His powers revolve around shadow.
- Evil Is Bigger: His shadow form rivals Atom Smasher in sheer size.
- Generic Doomsday Villain: He's not given any backstory, motive, or even a real name here, he's just around to be the antagonist for the first half of his self-titled episode, 3x06.
- Humanoid Abomination: Can take the form of a giant, human-shaped, living shadow.
- Living Shadow: He can become one.
- No Name Given: We never learn his real name.
- Weakened by the Light: As a shadow, he can naturally be hurt by enough bright light to the point where he'll revert to being human.
A criminal who had meta-human powers in the Flashpoint timeline. Upon regaining his powers and memories in the current timeline, he went on a killing spree, determined to kill all the police officers who arrested him in Flashpoint, regardless of their now non-existent history with him.
- Adaptational Superpower Change: Slightly different from in the comics, where he has the power to drain life force rather than decaying everything he touched.
- Brought Down to Normal: Wally is able to negate his powers by phasing his blood into him.
- Cop Killer: Zig-Zagged. He is out to kill the CCPD officers who arrested him in the Flashpoint timeline. However, in the current one, only Joe remains in the force while the rest took different paths due to the Cosmic Retcon (though one is retired and now works as a private investigator).
- Evil Is Petty: The people who arrested Yorkin in Flashpoint no longer have any idea who he is and have never done anything to him. He kills them in a horrifying manner anyway.
- Gotta Kill Them All: He seems to be after people who are law enforcers in the Flashpoint timeline.
- Immune to Bullets: Thanks to his degeneration powers, bullets disintegrate the moment they hit him.
- In Spite of a Nail: He's also a criminal in the Flashpoint timeline.
- Last-Name Basis: He was often called Yorkin.
- Logical Weakness: His blood has degenerative cells, so his powers can be negated with blood with regenerative cells.
- Make Them Rot: His main power is to decompose anything he touches.
- Moment Killer: Confronts Joe while the latter is in the middle of an important family dinner.
- Revenge by Proxy: He's out for revenge on all of the cops in the Flashpoint timeline who arrested him, even if their non-Flashpoint counterparts had no memories of the incident, or in some cases weren't even cops.
- Rogues-Gallery Transplant: Played With. In the comics, he is a Barry Allen villain. Here, most of his fights are with Wally and his feud is more personal with the biological West family.
- Touch of Death: His touch causes rapid cellular degeneration.
- Would Hit a Girl: He attacks Iris as Revenge by Proxy for Joe. His final intended victim is also a retired female CCPD officer.
Dark Matter Bus Metas
Ramsey Deacon / Kilg%re
Species: Enhanced Human
A wronged tech entrepreneur who gains the abilities of a living computer virus, using his powers to get revenge on his former colleagues.
- Adaptational Species Change: Comics Kilg%re is some kind of organic robotic being, while in the show he's a metahuman.
- Adaptational Superpower Change: Comics Kilg%re was electrokinetic and as a side effect could manipulate technology, while the show's version of Kilg%re can directly tap into and interface with technology.
- Ascended Fanboy: He claims he's a huge fan of the Flash and being able to control Barry's new suit is like him having a life-size action figure.
- Ax-Crazy: Kilg%re doesn't just want to get back at the people who wronged him. He wants them, and anyone who gets in his way, reduced to a greasy, red stain.
- Beard of Evil: He has a messy beard and a messy personality.
- Catch-Phrase: "Call me Kilg%re."
- The Cracker: Even without his powers, he's a skilled hacker who writes complex programs and can break through electronic locks.
- Heel–Face Turn: He claims to have been reformed after his stay in prison, and only delves in "legal crimes" such as the stock market.
- Glowing Eyes of Doom: His eyes glow with the same color as his encryption code whenever he uses his powers.
- Killed Off for Real: He dies after DeVoe drains him of his powers.
- Logical Weakness: Ramsey Deacon can only control electronic devices, which makes him unable to fight against devices without electronics.
- Named by the Adaptation: In the comics, Kilg%re wasn't human so never had a civilian name.
- Names to Run Away from Really Fast: His name sounds like "kill gore".
- Person as Verb: "Kilg%re" gets used by Team Flash for the act of metahuman technopathy, specifically once DeVoe acquires the power.
- Purple Is Powerful: His eyes turn purple whenever he uses his powers and his Calling Card encryption code that he leaves behind on machines is also purple.
- Soft-Spoken Sadist: He seems calm when speaking, but is a ruthless murderer. He speaks in a tranquil way when attempting to kill The Flash.
- Revenge: Deacon and three others developed the Kilg%re app together, but his colleagues sold it for billions behind his back, leaving Deacon with squat. After becoming a meta, Decon wants to use his powers to make them pay.
- Technopath: He has the ability to interface with technology via a techno-organic virus.
Rebecca "Becky" Sharpe / Hazard
Species: Enhanced Human
A down-on-her luck woman who gains the ability to manipulate her fortune, at the expense of jinxing the people around her.
- Adaptational Superpower Change: Comics Hazard used psionic powers in conjunction with mystical dice to influence probability. In the show she can create a quantum field that gives herself good luck and others bad luck.
- Affably Evil: Even when she's robbing a bank, she doesn't act with any malicious intent and more like she just so happened to be there to take money that wasn't attended. No matter what she does, she always carried a cheerful smile, and a sweet disposition. When defeated, she politely surrenders herself to Barry's custody. She pulls a full Heel–Face Turn when she expresses regret over her actions and allies with Barry during the prison break.Becky: (to Barry in a threatening tone) Do you really want to test your luck? Bad things happen to people who get in my way [...] (sweetly) Anyways there is nothing you can do to stop me! Toodles.
- Born Unlucky: Before getting her powers she had remarkably unfortunate luck. She lost her job on the same day she caught her boyfriend cheating, then broke a heel attempting to catch a bus after her car got booted.
- Cosmic Plaything: She was this before getting her powers, being Born Unlucky her entire life.
- Drunk with Power: Becky's not a bad person. Heck, she doesn't even believe she's a meta. She just sees her new-found powers as a way to make up for her life of bad luck, and the bad luck she's spreading to the rest of the world getting a "harmless" taste of what it's like to be her.
- Extreme Doormat: Before getting her powers she was extremely passive, refusing to so much as complain about getting a wrong order at the coffee shop that makes her sick.
- Freudian Excuse: Her entire life has been a series of bad luck, then everything inexplicably starts going her way. It's not surprising that she was so eager to take advantage.
- Go Through Me: She shields Barry from the other metas when they turn on him.
- Graceful Loser: After she asks The Flash if he could not arrest her and The Flash declines, she takes her arrest with stride.
- Grand Theft Me: In "True Colors", Becky has her body stolen by DeVoe.
- Heel Realization: After some reflection in prison, she realizes she was wrong to use her powers at the risk of the city like she did and wants to turn over a new leaf once Barry helps her escape.
- Hidden Depths: For a ditzy airheaded girl, she has a lot of anatomical knowledge as shown by when she bandages Barry's fractured hand. It's because she falls down a lot so has had he fair share of dealing with injuries.
- Hoist by His Own Petard: Her powers get canceled out by the same Particle Accelerator it accidentally turned on.
- Karma Houdini Warranty: Not her, but rather everyone else. Given her lifelong bad luck she sees her streak of good luck being compensation for everything she has been through, not realizing it's actually a meta-human power.
- Killed Off for Real: She dies after DeVoe takes over her body.
- Ms. Fanservice: She's easy on the eyes and wears clothes that shows-off her nice figure. Her casino uniform in particular gloriously flaunts her legs.
- Obliviously Evil: Becky merely desires to exploit her new lucky streak to the fullest, and while she does recognize other people are put out by the bad luck she spreads, she believes it to be harmless and seems none the wiser to just how deadly it grows. She constantly maintains her cheery personality and perky demeanor. Had she not been robbing banks and threatening Barry, Team Flash might have let her off with a warning.
- Redemption Equals Death: Once she reforms and helps Barry, DeVoe hijacks her body for him to use as part of his master plan, much to Barry's anguish.
- Token Good Teammate: In the team-up situation with the other Bus Metas, she was genuinely nice to Barry and the only one to be remorseful of her acts, which were less grave than the others'. She was with Barry even after Wolfe reveals Barry as The Flash.
- Unwitting Instigator of Doom: Her desires to exploit her good luck nearly caused a crisis throughout Central City, including the Particle Accelerator exploding and an airplane crash.
- Winds of Destiny, Change: She can alter probability, giving herself insanely good luck and everyone else an equal amount of bad luck.
Species: Enhanced Human
A meta with the ability to shed tears that can produce a euphoria like high in those who ingest them.
- Adaptational Heroism: Unlike the Weeper of the comics, he's never seen doing anything villainous.
- Bad Powers, Good People: Gaining his addictive high inducing teardrops has made, what can be assumed, his once normal life into complete hell.
- Blessed with Suck: His ability makes him a commodity on the black market, and as a result he is constantly beaten to produce his tears.
- Chekhov's Gunman: Despite being captured early on in the season no mention is made by either Marlize or DeVoe about jumping into his body when his current host is slowly dying. As revealed in Null and Annoyed the reason is that DeVoe never intended to take The Weeper's body; he made him because he knew that Marlize's empathy would eventually lead to her questioning him and wanted to use his tears to alter her memories and make her complaint.
- Distressed Dude: He's put through some of the worst hell possible thanks to his powers.
- Fantastic Drug: His tears are these producing a "love drug" that gives people an euphoric high. By combining his tears with Dominic's powers DeVoe is able to create a chemical compound that can alter memories which he uses on Marlize.
- From Bad to Worse: After spending weeks enslaved by Amunet's drug cartel, is finally freed and promptly abducted by DeVoe for some nefarious purpose.
- In-Name-Only: In the comics, the Weeper was a Golden Age gimmick villain with no powers and no connection to any version of the Flash.
- Killed Offscreen: [[spoiler:Maybe. DeVoe might have killed him at some point without his wife's knowledge since he uses his tears to mind control her. However it's not made clear if he absorbed The Weepers powers or just drained him of his tears so his fate is unknown.
- No Name Given: Is currently only known by his code name.
- Rogues-Gallery Transplant: Depending on the version, the Weeper is either an enemy for Bulletman and Bulletgirl, or a Marvel family villain. though he is a victim in this version, not a villain.
- Screw This, I'm Outta Here!: Bolts off after Iris frees him and offers Team Flash's assistance to him.
- Shirtless Captives: Was captured and left shirtless by Amunet to be tortured.
- Slavery Is a Special Kind of Evil: Is subjected to horrible conditions by Amunet and treated more like an object than a human being.
- Ungrateful Bastard: A downplayed example: Team Flash risked their lives to save him, and offered to help him get somewhere safe. Rather than take them up on this offer, he tells them to get away from him, and runs off into the night. Considering what he went through, it's hard to blame him for not trusting them...
- What Happened to the Mouse?: The Weeper is the only one of the Bus Meta's whose status by the end of season 4 is unknown since DeVoe didn't need his powers and was only keeping him around to use his tears to alter Marlize's mind and make her more compliant. Since we never see him again it's unknown whether DeVoe killed him or not.
- We Hardly Knew Ye: He was seen a few seconds before Iris rescues him and he runs away. Then DeVoe captures him and nothing is heard about him ever since.
Mina Chaytan / Black Bison
Species: Enhanced Human
A meta with the ability to bring inanimate objects to life.
- Adaptational Badass: In the comics Black Bison's powers come from magical artifacts. This version is a metahuman.
- Animate Inanimate Object: She can bring inanimate objects to life, such as a suit of armor or a stone jaguar.
- Badass Native: She is a Sioux who can control inanimate objects.
- Gender Flip: Black Bison is a man in the comics.
- Killed Off for Real: She dies after DeVoe drains her of her powers.
- Knight Templar: Taking Sioux artifacts back to her people is a very noble quest, but a willingness to hurt or even kill anyone she thinks has misused them, or who even gets in her way, renders her unsympathetic.
- Magical Incantation: She probably doesn't need it, but Mina recites a Sioux mantra while activating her powers.
- Would Hurt a Child: Mina has no problem endangering children.
Dominic Lanse / Brainstorm
Species: Enhanced Human
A meta with telepathic abilities.
- Adaptation Name Change: His codename was Brain Storm in the comics, while here it's Brainstorm.
- Adaptational Heroism: This version is a Tragic Villain who was forced into villainy rather than a petty supervillian.
- Distressed Dude: Gets captured and injured by Amunet and has to be saved by Caitlin and then her friends. Later Amunet captures the poor guy again and succeeds in selling him out to DeVoe, who promptly takes over his body.
- Grand Theft Me: Ends up on the receiving end from DeVoe.
- Killed Off for Real: He dies when DeVoe takes over his body.
- Rogues-Gallery Transplant: The Dominic Lanse Brain Storm was an enemy of Mr. Terrific rather than the Flash.
- Telepathy: Has the ability to read minds and give people a mental knockout, though he has to have visual contact for it.
Neil Borman / Fallout
Species: Enhanced Human
A man who unwillingly emits huge amounts of radiation.
- Adaptational Attractiveness: His comic counterpart looks like a skeletal corpse.
- Anti-Villain: He is not evil at all. He has absolutely no control over his powers and is freaked out by them just as much as the public.
- Bad Powers, Good People: His powers are harmful, but he just wants to lead a normal life.
- Blessed with Suck: Radiation powers should be cool right? Nope, it's a living nightmare as he has no control over his powers and they always end up harming everyone around him. It eventually kills him.
- Living Battery: DeVoe created him to be a power source for his satellite during the Enlightenment.
- Person of Mass Destruction: Eventually, his radiation levels reach such a high concentration that he is short of blowing up, with the same force of a nuclear bomb.
- Power Incontinence: He has no control whatsoever of his powers and has accidentally hurt people. He was sent to Tracy Brand and then A.R.G.U.S..
- Sickly Green Glow: Gives off a green glow when he's releasing radiation.
- Sole Survivor: The only bus meta who does not get killed by DeVoe hijacking his body or draining his powers, though he ends up being killed anyway to power a satellite for DeVoe's Enlightenment.
- Tragic Villain: He's not a villain period, his meta physiology just makes him dangerous to others and he has no control over it.
- Walking Wasteland: His mere presence causes people to faint because of the radiation.
- Yank the Dog's Chain: After Team Flash successfully brought him to a secure A.R.G.U.S. facility, DeVoe kidnaps him and forces him to serve as a Living Battery for his satellites.
Sylbert Rundine / Dwarfstar
Species: Enhanced Human
A thief who became a metahuman with the power to shrink anything he desires.
- Adaptational Superpower Change: His powers are subtly different in their application. His comics counterpart was basically an Evil Counterpart of Atom who was a Sizeshifter, while this Dwarfstar's powers are used more offensively as a biological Shrink Ray.
- Adaptational Nice Guy: He's still a villain but nowhere near as bad as his comics counterpart who was a rapist and a Serial Killer, with one of his many victims being the Atom. This version is a thief who steals whatever he desires, although he has no problems with killing a security guard and framing the innocent Big Sir for it, as well as callously shrinking people and throwing dangerous objects at them.
- Bald of Evil: Not a single hair on his head, and he is a very immoral thief.
- Celebrity Paradox: Cisco is seen wearing a Jason Voorhees T-shirt during the middle of The Flash Season 4. His actor played the character in the 2009 remake.
- Frame-Up: Frames Big Sir for a murder he himself committed.
- Improvised Weapon: Throws shrunken down objects like cars or even helicopters at his enemies who turn back to normal size mid-flight.
- Jerkass: He let Big Sir take the fall for a murder he committed, laughed about it when confronted with the crime, and refused to confess to the truth out of pure spite.
- Killed Off for Real: He dies after DeVoe drains him of his powers.
- Mythology Gag: While he underwent a Rogues-Gallery Transplant from The Atom to The Flash, he's still connected to the Atom by virtue of gaining powers from dwarfstar alloy, the same material that Ray Palmer's shrinking abilities come from.
- No Brows: He lacks eyebrows like Kyle Nimbus. While he is not as creepy as the latter, it still makes him scary.
- Rogues-Gallery Transplant: Dwarfstar is an Atom villain, specifically he's the Arch-Enemy of Ryan Choi the third Atom.
- Shrink Ray: He has the metahuman power to shrink anything he desires.
- Sticky Fingers: A notorious thief who can't help stealing just for the sake of it. Only his power to shrink things allow him to steal things like cars, military vehicles, and even a Kord Industries building.
Izzy Bowin / Fiddler
Species: Enhanced Human
An up-and-coming country musician with the power to create sound waves.
- Adaptation Name Change: Goes from Isaac Bowen in the comics to Izzy Bowin in the show, to accomodate the Gender Flip.
- Adaptational Heroism: Isaac Bowen was a supervillain, while Izzy Bowin just tries to lead a normal life.
- Composite Character: Has the surname and nickname of Isaac Bowen/Fiddler, but is female like his successor, Virtuoso.
- Deep South: Izzy speaks with a thick country accent.
- Gender Flip: Along with Age Lift. The Fiddler has traditionally been an old man in the comics.
- Instrument of Murder: Izzy can turn any sound waves into a powerful blast, but creating them from her fiddle playing helps her concentrate and control them.
- Kill the Cutie: Probably the most innocent of all the bus metas and she still loses her life.
- Make Me Wanna Shout: She can generate powerful focused sound waves.
- Personality Powers: What could be more fitting for a musician than sonic powers?
- Ship Tease: Izzy has quite a bit of teasing with Ralph in her debut episode and the guy is clearly smitten with her. Her death also ends up wrecking Ralph who decides to take the fight against DeVoe seriously and get justice for the bus metas.
- Too Dumb to Live: Because she was able to hurt DeVoe during their first encounter, she thought she could easily do so again. This directly lead to her death.
- We Hardly Knew Ye: She is killed and her body gets stolen by DeVoe in her debut episode.
Janet Petty / Null
Species: Enhanced Human
A career criminal who gained gravity-manipulating abilities.
- Card-Carrying Villain: Takes great joy in her robberies and has absolutely no problems with endangering the lives of civilians.
- Escape Artist: Even without her powers, she can easily escape cuffs.
- Flat Character: Has easily the least amount of character development of all the Bus Meta's.
- Gender Flip: The Null character in the comics was male.
- Gravity Master: Can make objects and even people fly by simply touching them. DeVoe also demonstrates they can be used in reverse too.
- Killed Offscreen: DeVoe takes her powers and kills her offscreen.
- No-Nonsense Nemesis: She does not fool around, immediately trying to kill Flash and taking civilian lives as leverage to escape.
- We Hardly Knew Ye: Killed by DeVoe during her second appearance.
Edwin Gauss / Folded Man
Species: Enhanced Human
- Adaptational Heroism: He is not a supervillain unlike his comic books counterpart.
- Extra Dimensional Shortcut: He has the power to enter his very own pocket dimension and exiting at various points, similar to DeVoe.
- Minor Major Character: One of the twelve bus metas created by DeVoe and supplies him with portal powers, but he barely had any screen time before DeVoe kills him.
- Totally Radical: He is a pretty textbook hippie.
- We Hardly Knew Ye: In his very first appearance, DeVoe steals his body.
Serums (Mirakuru, Velocity, Stardust, etc)
Species: Enhanced Human
A scientist at Mercury Labs who gained the ability of Super Speed by reverse-engineering the Velocity 9 formula initially created by Caitlin Snow and Harry Wells.
- Adaptational Curves: Her comic counterpart is more or less modestly endowed, which is justified since she's a teenager there. Here, she's well-endowed, though it wasn't explicitly shown outside of Freeze-Frame Bonus.
- Adaptational Villainy: Trajectory is a hero in the comics. Here, she's a villain who does things For the Evulz.
- Age Lift: In the comics, Trajectory is a teenager. Here, she's an adult working as a scientist.
- Aloof Dark-Haired Girl: As Trajectory, she loses her lass but gains so much sass.
- Boobs of Steel: She's a well-endowed, hard-hitting speedster.
- Brainy Brunette: She's a brilliant scientist who was able to reproduce the Velocity-9 despite her lack of knowledge on the formula.
- Chaos Is Evil: The Trajectory personality loves mad, devastating discord, the antithesis to orderly scientist Eliza.
- Chewing the Scenery: She speaks very theatrically.
- Composite Character: Her characterization and role in the plot is more in line with the comic version of Edward Clariss/The Rival, seeing as how she is also a Mad Scientist who artificially gives herself Super Speed and whose body distengrates from running too fast.
- Dark Action Girl: One of the most cutthroat opponents that Barry has faced in the series.
- Domino Mask: Part of her costume.
- Drugs Are Bad: She's deeply addicted to Velocity-9, and the acts of villainy are her riding the latest high.
- Drunk on the Dark Side: Causing chaos and abusing her powers gives her a deep thrill.
- Evil Former Friend: Eventually becomes this to Caitlin. It's implied that she's a False Friend from the get go.
- For the Evulz: She just wants to cause chaos for the hell of it.
- Hoist By Her Own Petard: Her addiction to Velocity-9 is what ultimately kills her.
- Hot Scientist: She's not at all bad-looking.
- Jerkass: She robs, maims and destroys purely For the Evulz.
- Jekyll & Hyde: Her normal personality often clashes with the Trajectory one.
- Karmic Death: While it's sad what happened to her, she caused a lot of chaos and had no regard for the lives she threatened or endangered. There was ultimately no one to blame for her death other than herself.
- Monster of the Aesop: She is used to teach Barry that he shouldn't take Velocity drugs.
- Never My Fault: Her Trajectory personality rationalizes that what's happening to them is Caitlin's fault for asking her help on Velocity-9.
- No Body Left Behind: Her body disintegrates as she dies.
- Race Lift: The character is black in the comics, but white here. For some reason, though, this interpretation of the character wears cornrows, a traditionally black hairstyle.
- Reality Ensues: Taking an experimental drug winds up having unexpected, and ultimately fatal side-effects. The fact that the drug was intended for use on a metahuman (which Eliza was not) can't have helped.
- The Scapegoat: She always makes it look like The Flash is the one who is doing her shenanigans.
- Self-Disposing Villain: After she takes even more Velocity-9 in the climax, she runs so fast that her body seemingly disintegrates.
- Small Role, Big Impact: She's a Monster of the Week who seemingly dies in her debut episode, but her death scene is what clues Barry in to the fact that Zoom is "Jay Garrick". Additionally, her costume was eventually used by Jesse once she herself becomes a speedster.
- Split Personality: Implied to be the cause of her addiction to Velocity-9.
- Superpowered Evil Side: The Trajectory personality is more dominant and in control of her Super Speed.
- Super Speed: Though she gains it through artificial means.
- Tempting Fate: Claims she'll see Flash again after taking her last dose of V-9... only to literally run herself to death.
- Villain of the Week: She is the first evil speedster who is this rather than a season-long Big Bad, until the Rival showed up.
- With Great Power Comes Great Insanity: She reverse engineers V-9, then gets hooked on it and develops a split personality.
Species: Enhanced Human
A drug-dealer who specializes in a drug called "Stardust", until after being thrown into a vat of Stardust, he emerges without feeling any sense of pain and gains advanced healing properties and body strength.
- Annoying Arrows: Justified due to his Healing Factor and his lack of pain.
- The Brute: Serves as this to Prometheus in Sampson's second appearance.
- Canon Foreigner: Derek Sampson has no counterpart in the comics; rather, the character mostly exists to give Stephen Amell's WWE rival Stardust a role on the show, after Amell himself participated in the 2015 SummerSlam against him.
- Create Your Own Villain: It's thanks to Rene's reckless actions and disregard for Oliver's orders that led to Sampson falling into a vat of Stardust and gaining superpowers.
- The Bus Came Back: After his Uncertain Doom at the end of "A Matter of Trust", he returns in "Honor Thy Fathers" having been released due to Adrian Chase's prosecutions being discredited. He then allies with Prometheus to help cause havoc in Star City.
- Feel No Pain: Played with - while his body doesn't register pain, his anatomy and its weaknesses are still the same as a human being. Lampshaded when the Green Arrow slices his tendons, making him unable to move.
- Freak Lab Accident: How Sampson gains his superpowers, courtesy of Rene.
- Healing Factor: Despite being shot by arrows and deliberately burning himself to prove his pain immunity to his goons, Sampson's body can regenerate small wounds.
- Nigh Invulnerable: Subverted. While his Healing Factor and immunity to pain allow him to shrug off relatively minor injuries, he's not invincible.
- Super Serum: Turns out coolant fluid mixed with Stardust is a formula for superpowers. Derek Sampson falls into a vat of the stuff.
- Super Strength: He seems to gain this as well as his inability to feel pain, likely by using Uninhibited Muscle Power.
- Tainted Veins: After being exposed to the Stardust mixture, the veins throughout his body can be visibly seen.
Species: Enhanced Humannote
After Ronnie sacrificed himself to save Central City, Professor Stein began to die without having another partner to fuse with. Luckily a young mechanic proved to be the ideal match.
- Attack Its Weak Point: The quantum splicer is what enables Stein's and Jax's Fusion Dance and when a brainwashed Rip Hunter disables it with an EMP, they de-fuse and unable to merge until it's fully functional again.
- Brought Down to Normal: A fatally wounded Stein gives Jax a serum to remove their Psychic Link and Fusion Dance capabilities in order to prevent the latter from also dying.
- Civvie Spandex: He is wearing Jax's casual clothes in his first outing as he is in a hurry due to Tokamak wrecking havoc at the time. Starting with his second appearance, however, he's been wearing the red and yellow comics costume every time his two components fuse together.
- Composite Character: Puns aside, the second version of Firestorm in the comics is Jason Rusch (who already appeared in the first season). Jefferson Jackson is merely Ronnie's Black Best Friend there. This version of Firestorm is clearly inspired by Rusch's tenure.
- Double Consciousness: A literal example like with Ronnie, with two conscious minds sharing the same body.
- Energy Absorption: Absorbs the blast from Vandal Savage's nuclear warhead, containing the fallout to a safe levels.
- Fire-Forged Friends: Literally and figuratively, though their initial relationship wasn't as nearly rough as it was with Ronnie.
- Flaming Hair: Same deal as the first one.
- Flying Firepower: He can also fly.
- Fusion Dance: Much like the first one. On a meta-level, Franz Drameh and Victor Garber even did the actual Dragon Ball Z Fusion Dance pose.
- Glass Cannon: Easily the most powerful of the Legends in terms of raw power, but goes down in one hit from Barry's lightning attack in "Invasion!" and a single arrow from Merlyn in "Aruba," the latter even causing him to de-fuse.
- Hand Blast: His primary means of attack and flight, aiming his hands downward enough force to defy gravity and allow for stable propulsion and gliding.
- How Do I Shot Web?: Originally until Stein gave him some pointers.
- Iconic Sequel Character: Does not appear until The Flash (2014) Season Two.
- Legacy Character: Succeeded Ronnie as the host body for Firestorm.
- Matter Replicator: In the Season One finale of Legends , he discovered a new power. Just as in the comics, Firestorm can now transmute elements and he turned a Thanagarian meteor into a large puddle of water.
- Playing with Fire: Same deal as his predecessor.
- Prophet Eyes: Using his abilities makes his eyes turn completely white.
- Psychic Link: Due to being fused together in the Firestorm matrix, Jax and Stein both feel when the other is in great distress or pain.
- Salt and Pepper: He's a combination of a Caucasian man (Stein) and an African-American man (Jax).
- Story-Breaker Power: Being the most powerful Legend who could single-handedly handle most of the threats the team encounters, Jax and Stein often find themselves physically separated from each other when the plot demands it.
- Superior Successor: If only because he's able to at least learn about his molecular transmutation skill that the Ronnie/Stein version didn't.
- Walking Spoiler: It's hard to talk about him without discussing the aftermath of the first season.
- Wreathed in Flames: In general whenever he uses his powers.
Species: Enhanced Human[
A scientist who incessantly wants to become the meta-human Firestorm after he was offered the chance. He does not take it well when he and Stein turns out to be incompatible.
- Angry Black Man: Turns out Hewitt is this, and has had run-ins with the law. Getting imbued with tachyon particles does not help matters.
- Age Lift: In the comics, Hewitt is an elderly multimillionaire who turns himself into Tokamak to restore his youth.
- Alliterative Name: Henry Hewitt.
- Bitch in Sheep's Clothing: Comes off initially as a well-meaning young man who shows deference to Stein as an accomplished colleague, who simply seemed particularly confident about his "destiny" to aspire to greater things. But as soon as things didn't follow his expectations, he quickly shows his true colors; hot-headed and temperamental.
- Black and Nerdy: He's a brilliant scientist and recognizes a nerdy reference from Cisco.
- Energy Absorption: Gains this after his failed merger with Stein, draining power from nearby sources.
- Entitled Bastard: He really thinks that he deserves to be Firestorm, which is why he's incompatible with Dr. Stein.
- Evil Counterpart: To Jax. Both were candidates to become Ronnie's successor as the host body for Firestorm, but while Jax is reluctant about the matter, Hewitt is entitled to the point of delusion. They have parallel backgrounds, too; Hewitt couldn't find a stable job due to his smug attitude, while Jax compromised his promising football career by doing something noble. Having the same race as well as having Alliterative Names is probably another bonus.
- Hair-Trigger Temper: Another big reason Hewitt isn't the right partner for Stein. Unfortunately, this comes up after he gets powers from trying to merge with Stein.
- Hand Blast: Can generate the energy he absorbs and release it as powerful blasts from his hands
- Insufferable Genius: Hewitt is brilliant, he knows it, and he thinks this instantly makes him better than anyone else; this attitude was already causing him some job issues before he gained powers.
- It's All About Me: As if him being an Entitled Bastard indicates, he cares only for himself and his goals.
- Jerkass: Insults Caitlin for getting his hopes up on becoming Firestorm, berates and threatens his boss who rightly grills Hewitt for his tardiness and poor work ethic, and openly slanders Jefferson for replacing him.
- One Steve Limit: Averted. He shares his first name with Barry's father.
- Power Glows: Has a reddish orange aura after his powers are triggered.
- Race Lift: He's Caucasian in the comics.
- Smug Snake: The moment it's clear that he can't be Firestorm, he flips out.
- You Wouldn't Like Me When I'm Angry: Hewitt's attempt to merge with Stein results in his gaining fire powers fueled by rage. Fortunately, Firestorm and the Flash are able to make him burn himself out before he can do too much damage.
Species: Enhanced Humannote
After witnessing Firestorm II in action during 1975, Vandal Savage hired Soviet scientist Valentina Vostok sometime between that year and 1986. They began creating their very own version of Firestorm, having had 10 years to research his abilities before Rip Hunter reappeared. The project to create Firestorm was dubbed "Operation Svarog", in honor of an ancient Slavic god of fire.
- Adaptational Villainy: Vostok is usually a hero in the comics.
- Aloof Dark-Haired Girl: Her host body is very rigid even before her forced Fusion Dance with Stein.
- Composite Character: Puns aside, the Soviet Firestorm in the comics is Mikhail Arkadin (who already appears as her ally), while Valentina Vostok is the Negative Woman.
- Does This Remind You of Anything?: The forced Fusion Dance between her two components is literally forcing someone to be inside of you.
- Double Standard: Rape, Female on Male: Averted Trope. The way she talks about merging with Stein, and how she forces him to do it, brings to mind a form of rape, and it is most definitely not okay.
- Evil Is Burning Hot: A fire based supervillain.
- Evil Knockoff: Her host body is ordered to create a version of Firestorm after her boss witness Jax and Stein in action.
- Flaming Hair: Same deal as the first two.
- Flying Firepower: She can also fly.
- Fusion Dance: Unlike the first two, Stein is forced into merging with this one.
- Gender Flip: The Soviet Firestorm in the comics is male. Said male character appears, though.
- Hand Blast: Her primary means of attack and flight, aiming her hands downward enough force to defy gravity and allow for stable propulsion and gliding.
- Hoist by Their Own Petard: Forces Stein into a Fusion Dance despite his warning of the dangers of doing it without wearing a Quantum Splicer (as was the case during Stein and Ronnie's initial merge). The move literally blew up on her face (along the rest of her body) when Jax pulls out Prof. Stein out of her.
- How Do I Shot Web?: She has little control of her powers, and Stein certainly doesn't want to give her some pointers.
- "I Know You Are in There Somewhere" Fight: A literal example. Jax calls out to Prof. Stein repeatedly during The Legends' fight with her, which succeeds.
- Playing with Fire: Same deal as her predecessors.
- Prophet Eyes: Using her abilities makes her eyes turn completely white.
- Sensual Slavs: A literally and figuratively hot Russian.
- Tall, Dark, and Snarky: She's very smug and hostile and also the tallest (5'11) woman on Earth-1 to date.
- Unskilled, but Strong: She is able to produce fire much stronger than both the Ronnie and Jax versions, but has little control of her powers.
- Wreathed in Flames: In general whenever she uses his powers.
Species: Enhanced Human
A meta-human who has the ability to harness and weaponize plasma though his eyes and absorb electricity. He's already a notorious bank robber before gaining his powers.
- Aborted Arc: When getting incarcerated, it seemed like the next time he would appear the mystery about how he got his powers before the Particle Accelerator accident would be revealed. Instead, he was unceremoniously killed off by Captain Cold and nothing about his origin has been revealed up to date.
- Apologetic Attacker: Apologizes to Felicity before telling her he's going to kill her.
- Boom, Headshot!: From Captain Cold's Cold Gun, no less.
- Energy Absorption: His main defensive power.
- Enhanced Punch: Can channel his energy into his fists, allowing him go toe to toe with Ray in the A.T.O.M. suit..
- Evil Vegetarian: A deleted scene from "Grodd Lives" reveals that he will only eat vegan food.
- Eye Beams: One of the ways he uses his offensive power.
- Facial Horror: Getting blasted point blank with Cold's Freeze Ray causes his face and neck to become severely frost bitten.
- Killed Off for Real: Gets lethally blasted in the face by Colds Freeze Ray in Rogue Air.
- Lean and Mean: He is skinny and quite an ass.
- One Of These Is Not Like The Others: Unlike the rest of the pipeline's inmates, he didn't get his powers from the Particle Accelerator explosion.
- Only Sane Man: In "Rogue Air", he's the more reasonable metahuman prisoner, trying to breakup a fight between Mardon and Nimbus, to no avail.
- Outside-Context Problem: Zig-Zagged. He is certainly not the first metahuman villain in the Arrowverse, but he is one for Team Arrow who usually deal with Badass Normals with the exception of Slade, and even then he didn't have the same powers like other metahumans. He is, however, the first metahuman who did not receive his powers from the Particle Accelerator and how he got his powers is still a mystery.
- Plasma Cannon: His main offensive power.
- Power Glows: His eyes and fists glow red when he charges up for fighting.
- Red Eyes, Take Warning: His eyes becomes red before shooting his Eye Beams.
- Remember the New Guy?: If you don't watch Arrow or missed that show's episode where he showed up, chances are you have no idea who the hell he is.
- Rogues-Gallery Transplant: Deathbolt is an All-Star Squadron villain in the comics. Counts as In-Universe too, as he was transplanted from Star(ling) City upon being defeated by Ray Palmer/The Atom.
- Small Role, Big Impact: He dies after being in two episodes (one of which was on Arrow), but his existence has massive implications for the Arrow/Flash universe.
- Starter Villain: For Ray Palmer, being the first true threat he faces solo as the Atom, not counting Oliver.
- Super Strength: He's got more physical strength than the Atom's Power Armour.
- Unskilled, but Strong: The Atom (remote-controlled by Green Arrow) took him down using nothing more than boxing jabs.
- We Hardly Knew Ye: If you only watch The Flash or didn't see his debut in Arrow, then he gets very little in the way of personality traits before his untimely demise.
- Would Hit a Girl: Tried to choke Felicity to death.
Species: Enhanced Human
A metahuman with the ability to create earthquakes who arrives in Central City while Barry, Cisco, and Wells are out of town.
- Blood Knight: He desperately wants to fight the Flash.
- Chewing the Scenery: He speaks very theatrically.
- Dishing Out Dirt: His power is to create earthquakes.
- Evil Is Hammy: He's Chewing the Scenery everytime he speaks.
- Hero Killer: At least aspires to be one, as he claims that he loves seeing heroes fall and never get up again.
- Generic Doomsday Villain: Lacks any real personality aside from wanting to cause destruction and fight the Flash.
- Glory Seeker: The only real motive given for his actions.
- Goggles Do Nothing: He has goggles as part of his attire.
- Movie Superheroes Wear Black: His outfit is almost completely black, with some red under the armor; it's a fair bit more colorful in the comics.
- Rogues-Gallery Transplant: Geomancer is usually an enemy of the Justice Society of America, including Jay Garrick. As a possible nod to this, in Geomancer's appearance here, he fights a man posing as Jay Garrick.
Norvok / Snake Eye / Medusa Man
Species: Enhanced Human note
Amunet's third-favorite henchman who is a meta with a tentacle in place of one of his eyes.
- An Arm and a Leg: Or tentacle in this case. Rather than killing him, Amunet resorts to cutting out his tentacle.
- Awesome, but Impractical: A tentacle eye sure sounds useful and menacing, but he can't fight for shit and gets beaten up by girls with no powers. But then his powers got an upgrade.
- Chekhov's Gunman: He's seen passing by Caitlin in "The Flash Reborn" without any indication he would be a significant character, however by the end of the episode he's revealed to work for Killer Frost's former boss Amunet, and tries to stop her from leaving... with little success.
- The Dragon: Used to be a Co-Dragon with Caitlin before the latter quit. Later becomes The Starscream.
- Et Tu, Brute?: Amunet does not take to kindly of Norvok's betrayal.
- Eye Scream: There's a tentacle in his eye socket which Amunet later cuts out.
- Lovecraftian Superpower: His power is a super-strong tentacle that comes out of his eye socket. Eeew.
- Not-So-Harmless Villain: He was initially so pathetic in battle he might as well have been a Joke Character, but then he Took a Level in Badass and he proves to be quite dangerous on his own.
- Took a Level in Badass: After taking over Amunet's organization, he developed a weapon to counter his former employer's powers and his own powers evolved into being able to produce a venom strong enough to incapacitate the Flash.
Matthew Kim Metahumans
Species: Enhanced Human
- Chewing the Scenery: His speaking patterns play everything up to the most dramatic effect.
- Evil Is Burning Hot: Yet another fire based supervillain. He's stated to be as hot as lava.
- 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.
- Playing with Fire: Was accidentally given fire powers when Matthew Kim swapped them from another evil meta.
- Required Secondary Powers: His powers come with an extreme resistance to heat. In addition to producing fire, he can be at the center of his fiery vortex and remain completely unharmed.
- 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.
