Main Characters

     Barry Allen/The Flash 

Bartholomew "Barry" Allen

"To understand what I'm about to tell you, you need to do something first: you need to believe the impossible."
Known Aliases: The Flash, "Red Streak", The Fastest Man Alive, The Scarlet Speedster
Played By: Grant Gustin

An assistant crime scene investigator in Central City with a habit of ducking work to investigate strange phenomena. He first appears in-universe in the mid-season 2 two-parter in Arrow investigating a break-in by a thief who apparently has Super Strength. After being struck by lightning, he falls into a coma and awakens as a "metahuman" with Super Speed.
  • Adaptation Dye-Job: Barry Allen has light blond hair in the comics, but is portrayed with dark brown hair on the show.
  • Adorkable: Portrayed this way ever since his first appearances on Arrow.
  • All Love Is Unrequited: Downplayed. Felicity Smoak is genuinely fond of him, but he's more interested in Iris West, who considers herself and Barry Like Brother and Sister.
  • Agent Mulder: Perfectly willing to accept that one guy with super-strength was behind the break-in at the Queen Consolidated warehouse, and actively seeks out weird cases.
  • All of the Other Reindeer: Henry wanted him to change his surname so people would stop giving him grief about being related to a (albeit innocent) murderer.
  • Awesomeness by Analysis: Displays this ability in the pilot, knowing a car's exact make and model based off of faint tire tracks left at a crime scene.
  • Badass: Fastest man alive and all that.
  • Badass Adorable: Barry is nerdy, loveable and incredibly endearing but DO NOT underestimate him as he can kick ass like no other.
  • Badass Bookworm: Police forensic scientist person gets superpowers and fights crime.
  • Bad Liar: Joe and Iris seem to think so.
  • Beauty Is Never Tarnished: His face doesn't typically suffer anything severe, save for a few nicks and dings. Justified, as he heals at a much faster rate than your regular human.
  • Because Destiny Says So: Oliver thinks that lighting bolt wasn't random:
    Oliver: I don't think that bolt of lighting struck you, Barry; I think it chose you.
  • Berserk Button: He is put-off everytime he hears that he's being referred to as "The Streak".
  • Beware the Nice Ones: Barry is generally a nice guy but if you cross him or hurt anyone that he cares about, he won't hesitate to kick your ass.
  • Big Damn Kiss: Finally kisses Iris before going to save her father, but with his discovery of time travel at the end of the episode this is erased.
  • Big Eater: It turns out that his Super Speed speeds up his metabolism too, and if he doesn't eat heavily, he collapses from hypoglycemia. He also can't get buzzed by alcohol unless he drinks ultra-high concentrated alcohol, and even then, it only lasts briefly.
  • Birds of a Feather: With Felicity Smoak.
  • Boy Next Door: He is considerate and selfless. In the case of Iris, literally next door, as he lived with her growing up.
  • Broken Pedestal: Barry idolized the Arrow but upon actually meeting him he is seriously off put by who much of a jerk Oliver can be. Similar things happen in subsequent crossovers with Barry's initial enthusiasm getting derailed by Oliver's more brutal methods. Ultimately subverted when Barry learns to see Oliver / The Arrow as an ally with his own strengths and flaws rather than an idol.
    • The Flash becomes a Broken Pedestal to Iris when he brutally attacks Eddie while under a Hate Plague.
    • As of "Rouge Time" Wells seems to have finally become on to Barry after he murders Mason Bridge to keep his identity secret prompting Barry to reconsider what Mason and Joe said regarding Wells' true nature.
  • Bully Hunter: He's aggressively anti-bully, especially since he had to deal with them a lot as a kid. Best shown in "The Flash Is Born" when he goes after one of his childhood bullies and now metallic metahuman, Tony Woodward.
  • Butt Monkey: In the first episode alone he gets battered by a mugger, struck by lightning & goes into a coma for 9 months, all in the space of an evening, then wakes up to find that the woman he's in love with has begun a relationship with another man during said coma. But hey, he gets Super Speed.
  • The Cape: Barry is basically the counterpart to Oliver Queen's The Cowl. The two-part crossover of "Flash vs. Arrow" on The Flash and "The Brave and the Bold" on Arrow is an extended look at how Barry's city is clean and nice and had to be bombarded with metahumans before it needed a hero, one like Barry, who's sweet and kind, contrasting them with Oliver and his city. Once he's revealed to the public, he fully embraces being a symbol of hope for Central City.
  • Cassandra Truth: The only people who truly believed Barry's story about his mother's murder were... Barry & his father, who were the only people to witness it. Many flashbacks show a tearful ten year old Barry trying to convince people to let his dad go. Present-day Barry is still very bitter over this fact.
  • The Cast Showoff: Grant Gustin gets to show his amazing singing voice in "Crazy for You".
  • Character Development: Barry has become more forceful and driven than he was during his first appearance on Arrow; stammering a lot less and interacting with more ease, which he might owe to his powers. According to the creators, it won't stop there...
    Andy Kreisberg: It's Barry Allen coming to terms both physically and emotionally with what's happened to him. He's not really The Flash yet because he's still in the early days. By the end of the year, he will come to resemble The Flash that we know from the comic books. That's really the arc for the first year.
  • Chick Magnet: He's been involved, or at least had a Ship Tease, with four women in the first season alone, namely; Iris, Felicity, Caitlin and Linda.
  • Clark Kenting: Cleverly averted, as most of the people who get a clear look at him in action already know about him. When he has to appear in front of people not in the know who might recognize him, he vibrates his face so it becomes a blur, and also his vocal chords.
  • Clear Their Name: Knows his father is innocent and won't rest until everyone else knows it too.
  • Cloudcuckoolander: Has a vested interest in weird crimes which can't be explained with pure fact and logic, due to his mother's death being such a case. Detective West repeatedly tells Barry to stop looking into such cases & accept that his father killed his mother, not a "ball of lightning with a man inside."
  • The Cloudcuckoolander Was Right: Considering Barry himself becomes the fastest man alive and Clyde Mardon can control the weather, Detective West realises that Barry was right about everything upon seeing it for themselves.
  • The Coroner: He works for the CSI unit of the CCPD.
  • Deadpan Snarker: Barry can thrown in a snide comment when the moment calls for it.
  • Determinator: He'll flip cars to catch local Central City baddies.
  • Dogged Nice Guy: To Iris West.
  • Dork Knight: He's a bit awkward and is prone to geek-outs, but he's brave and has a big heart.
  • Dude, Where's My Respect?: Not as the Flash, but in his day job most of the CCPD (sans Joe and Eddie) seems to take him and his forensic work for granted.
  • The Everyman: Of a sort. Barry is a lot geekier than the average Everyman character, but that fits with the show's target audience of comic book/sci-fi fans.
  • Fish out of Temporal Water: Due to being in a coma for 9 months, he's a little out of it.
  • Foreshadowing: When he messes about with the chemicals in the lab, making comments about how it's dangerous to have them so close together, Felicity responds that maybe he shouldn't be touching them. Cue a lightning strike and Barry looking out at it for a few seconds. This is a nod to the most well-known of Barry's origin stories: getting doused in chemicals after a lightning bolt knocks him into it. At the end of "Three Ghosts" in Arrow, this is indeed how Barry gets his powers, with the lightning bolt being generated by Star Labs' overloaded particle accelerator.
  • Fragile Speedster: Comparatively - despite being more resistant to harm than the average person thanks to his super speed, Barry will still injure himself if he runs into something at said speed. Plus, at least at first, he can't fight at all.
  • Freak Lab Accident: See above: he warns Felicity about how to avoid them. Then, as you may have guessed, Irony kicks in and he is the victim of one.
  • Freudian Excuse: He couldn't help his dad get acquitted of his mother's murder, so he when he gets his powers he jumps at the chance to help people over the city.
  • Friendly Rivalry: With Oliver Queen.
  • Future Badass: If Wells' 2024 news article is any indication.
  • A God I Am Not: Executed beautifully in one line.
    Mardon: I didn't think there was anyone else like me.
    Barry: I'm not like you. You're a murderer.
  • Good Feels Good: He loves helping people.
  • Good Is Dumb: Not usually, but Barry has a blind spot when it comes to Dr. Wells. Until he sees the headline that Mason Bridge, the reporter who's been going after Wells is missing. Then he finally sees the painfully obvious.
  • Green Eyes: They're blue in the comics, but green here.
  • Happily Adopted: While adopted at an older age under distressing circumstances, Barry did end up being a true part of the West family. Reciprocated by Joe, who admits that Barry brought a lot of joy and warmth to the West household.
  • Healing Factor: A side-effect of Barry's power, which speeds up his healing process.
    • Comes in incredible handy in "Revenge of the Rogues". In order to defeat the Rogues, he needs them to fire their guns at each other. Ultimately, the only way to do this is to briefly endure their fire and ice blasts coming at him from each side before running out of the way. Given that the guns were absolute zero and absolute heat, this would have easily killed any normal human.
  • The Hero: Of the show, considering that the series revolves around Barry and his journey as a superhero.
  • Hope Bringer: To the people of Central City. When he fully reveals his existence to the whole city, he embraces this.
  • Hot Scientist: Genius-level intellect and a day job as a forensic scientist? Check. Clear skin, styled hair, and abs? Double check.
  • Hyper Awareness: His brain can work at Super Speed, which allows him to perceive things more slowly than they really are. It automatically activates when he's running, though he can willingly use this ability outside of Super Speed if he needs to.
  • In a Single Bound: By building up enough momentum, Barry can leap really high. He utilizes this in the first episode to save Joe and Eddie from falling debris.
  • I Want My Beloved to Be Happy: Confesses to Iris, but is acting like this for the time being.
  • The Knights Who Say Squee: Even after he develops his powers, he still thinks Oliver Queen's grappling arrow is cool and relies on him for support.
  • Jumped at the Call: Very eager to use his powers to help people.
  • The Lab Rat: His day job at the Central City PD.
  • Late for School: Or perhaps Late For Absolutely Everything. At first, though he likely won't have to deal with that for too long.
    • Even with super speed he's still late to crime scenes, mainly because of other heroics.
  • Let's You and Him Fight: In Arrow vs Flash, Barry has been hit with the Hate Plague and they get into a fight. Ends in a draw, as the fight is interrupted before either can secure victory.
  • Love Hurts: He's flat-out told by Oliver that it won't end well in with Iris and at the end Flash vs Arrow she never wants to see The Flash again, but she changes her mind after the Big Damn Hero moment he pulls against Captain Cold and Heatwave
  • The Masquerade Will Kill Your Dating Life: He's learning this the hard way during his dates with Linda.
  • Morality Pet: To Oliver Queen. One of many Oliver has.
  • Motor Mouth: It's hard to get him to stop once he starts talking.
  • Mr. Fanservice: He doesn't have a shirt on much of the time whenever Star Labs is running tests on him. Lightning gave him abs!
    • In "Plastique" he strips naked in an alley. Yeah, "The Flash" indeed.
  • Nerds Are Sexy: Considering that he is a scientist who is a combination of Adorkable and Mr. Fanservice, Barry definitely qualifies as a very attractive nerd.
  • Nice Guy: Goes along with his being so Adorkable; he's very friendly and empathetic, and he'll put his life on the line for strangers and friends alike. But, as always, Beware the Nice Ones.
  • Nice Shoes: Barry seems to have a thing for Converse All-Stars.
  • Odd Friendship: With Oliver Queen, AKA The Arrow. They're not far apart in age (Oliver is about 4 years older), but Oliver's experience and experiences make him the older, gruff, almost unwilling mentor to Barry's eager kid. In their first crossover (not the backdoor pilot), they both feel out of place in one another's series, as Oliver is the brutal cowl and Barry the idealistic cape. They're the DC Television Universe equivalent of Bruce Wayne and Clark Kent.
  • Oh, Crap: When he travels back in time to the previous night in "Out of Time", he is visually perplexed and frightened.
  • Older Than They Look: Earning him the nickname "Babyface". He's 25.
  • Omnidisciplinary Scientist: Barry seems to be the only crime scene/forensics tech CCPD has. In "The Man in the Yellow Suit" he mentions that he had a double major in physics and chemistry in college.
  • Parental Abandonment: Barry's mom was murdered when he was eleven, and his father was convicted for the murder.
  • Pop-Cultured Badass: The fastest man alive likes "Pokerface" by Lady Gaga. He's got a blog according to Eddie and a Facebook account according to Cisco.
    • He also has a zombie movie scale and even rates one film at a 4.
      Iris: There's a zombie movie scale?
  • Power Perversion Potential: The fact that he can vibrate an isolated part of his body such as his face has some rather exciting implications for any significant other he may have.
  • The Power of Friendship/The Power of Love: The STAR Labs gang realizes that his devotion to his loved ones are what give him greater strength.
  • Red Baron: Appropriately, the Scarlet Speedster/Knight.
  • Red Is Heroic: Barry's entire Flash costume is red.
  • The Runaway: After his dad was convicted, and he was given to Joe he would runaway a lot trying to see his dad.
  • Sad Clown: According to a comment from executive producer Greg Berlanti.
    Berlanti: Barry lost his mother at a very young age, his father was sent to prison for murdering his mom, he went through a lot of stuff - on the surface he's bubbly and upbeat and seems like an optimist, but deep down maybe there's no hope left.
  • Science Hero: Barry works in a science lab and he saves innocent people on the side.
  • Secret Identity: According to Grant Gustin, Barry will try to keep his activities as the Flash secret from certain people but most of the people in his social circle will know the truth.
  • Secret Keeper: Mutually with Oliver Queen/The Arrow.
  • Self-Deprecation: Mocks the name "Leonard", saying it's nearly as bad as "Bartholomew", which is his given name.
  • Sensitive Guy and Manly Man: Everytime he and Oliver are together, he's usually depicted as the sensitive one.
  • Sherlock Scan: Barry is able to discern exactly what type of car the Mardon brothers used in their getaway from a robbery from analyzing a tire track, and figure out a vague location from a piece of excrement mixed with the track; all within a minute and without the use of any equipment.
  • Socially-Awkward Hero: He has trouble relating to other people.
  • Ship Tease: With Felicity Smoak in Arrow. Also a few times with Caitlin.
  • Smug Super: Occasionally displays traces of it.
    (Regarding the salmon ladder) Honestly, I don't know what's so hard about this.
  • Spear Counterpart: To Felicity Smoak. Both are Adorkable, have a tendency to babble, and are brilliant in their respective scientific fields.
  • Spiky Hair: It's like it's always in clay dough.
  • Superhero Origin: His is told in the Arrow episodes "The Scientist" and "Three Ghosts", and is expanded upon in the pilot episode.
  • Super Speed: His primary ability.
  • Super Speed Reading: Uses it to help Caitlin look for clues on the "F. I. R*. E. S. T. O. R. M." project.
  • 10-Minute Retirement: Very briefly quit being the Flash due to getting his ass kicked in his first fight with Multiplex and Joe chewing him out. Fortunately, he gets the motivation back quickly.
  • Thou Shalt Not Kill: He prefers saving lives to taking them. It doesn't matter if a person is some innocent bystander or the Villain of the Week; he'll try to save them.
  • Took a Level in Badass:
    • Does this during his fight with Clyde Mardon.
    • Goes even further after losing his powers to Blackout and regaining them to new heights. Before then, he had to make a massive running start to break the sound barrier. Afterwards, he is able to Flash Step to avoid lightning. Even Caitlin notes that his cells are generating more energy than they were before.
    • In "Out Of Time", he needs to protect the city from a tidal wave headed its way. The solution, according to Caitlin? Run back and forth on the beach to generate a second tidal wave in the opposite direction to cancel the first one out. However, this requires going faster than he's ever had to before, to the point where he unintentionally goes back in time. Barry can now travel back in time.
  • Twinkle in the Eye: It is quickly becoming a trademark that whenever the Flash is about to do something utterly ridiculous with his speed, lightning bolts are seen sparking in his eyes.
  • Two First Names: Being a DC Comics based character, he has a last name that is traditionally used as a first name.
  • Unlucky Childhood Friend: Other than his father being framed-up, being this is his personal dilemma. He seems to be working this out as of episode 12.
  • Unskilled, but Strong: Barry has his superspeed, but he doesn't have a lot tactical or martial arts training. This tends to let him get hit by surprise attacks a lot.
  • Voice of the Legion: Can vibrate his vocal cords to get this effect when talking to Iris and others not in on it, as his own version of the Arrow's voice modulator.
  • Weirdness Magnet: Well, not so much a "magnet" since he readily goes looking for the weirdness. To be fair, he never thought he'd actually become the weirdness in the process.
  • What the Hell, Hero?: Delivers this to Wells, calling him out on his Manipulative Bastard tendencies and general selfishness.
  • Willfully Weak: It's indicated several times that he holds himself back due to combination of self-doubt and the bad memories of his mother's death.
  • You Are Better Than You Think You Are: Even after he gets his powers, he still has doubts as to his capabilities in part because of Joe's dissaproval of his heroics.
    • In a conversation with Caitlin he admits that he thinks that best part of him is the Flash, and not his civilian idenity.
    Caitlin: With or without your speed, you're still you Barry.
    Barry: No I'm not. I'm not the best version of me.
    • Gives one of these to Oliver when he feels that what he does as the Arrow is consuming him. Barry assures Oliver that he can inspire people not as the Arrow, but as Oliver Queen.
  • You're Not My Father: After Joe comes down hard on Barry for risking his life by fighting other metahumans and engaging in dangerous superheroics, Barry fires back by saying he is not Joe's kid and that his father is still sitting in prison for a crime he didn't commit.

     Harrison Wells 

Dr. Harrison Wells

"The man in the red mask, the fastest man alive. He must be"
Played By: Tom Cavanagh

A scientist searching for metahumans who helps Barry understand his powers. There is a lot more to him than meets the eye, however.
  • Ambiguously Evil: He's actually either from the future (at least the year 2024, a point in time where the Flash disappears and the sky turns red), or has somehow acquired information and technology from at least as far into the future as 2024. In the second episode, he kills Simon Stagg who wants to capture Barry for experimentation, saying "he must be kept safe". We don't know if he wants to make sure that future happens, or if he wants to prevent it. It gets muddled further when we see a flashback during the explosion where we see him in his secret room, watching Barry getting struck by the bolt. He wanted the explosion to happen. Complicating things further is that both he and the Reverse-Flash like using knives to kill people.
    • It turns out he actually is the Reverse-Flash, or at least one of them, if multiple versions are being used.
    • We actually see him running (and leaving a trail of red lightning) in "The Sound and the Fury", proving he is indeed the Reverse-Flash.
    • Another twist shows up in "The Nuclear Man" when bloodstains found at Barry's old house are found from the night of Nora's murder and seemingly neither of them match Wells, implying that there is more than one Reverse-Flash.
    • "Fallout" shows him unmasking while in the Reverse-Flash costume, finally putting any doubts to rest. Also, he's perfectly aware that Grodd is living in the sewers and they seem to have some sort of alliance.
    • "Out of Time" throws out the ambiguity for good. He reveals himself to be Eobard Thawne; he's stuck in the past, he was actually attempting to murder Barry as a child the night Barry's mom died, and the only thing that can help him to return to the future is Barry's speed. Then he puts a vibrating hand clean through Cisco, though this is undone by Barry accidentally traveling back in time.
  • Apologetic Attacker: One of the last things he tends to say to people he kills is "forgive me". Whether or not he really means it is up to interpretation.
  • Badass Boast: He delivers one without even raising his voice, giving a chilling tone to his words.
    Wells: Threaten me again, and I will end you. And I am not talking about your career.
  • Bad Guys Do the Dirty Work: It's almost as if he personally chose to be Ambiguously Evil as a way to protect Barry by killing anyone who could be a true threat.
  • Berserk Button: Do not harm Barry, even indirectly. He is enraged when he finds out that, behind his back, Cisco made a freeze gun to counter Barry if he ever went rogue, and left said weapon carelessly in a locker. This turns to be a case of Pragmatic Villainy, as Barry's speed is the only thing that can send him back home.
    • Incidentally, any weapon designed to counter Barry would also counter him, which makes Cisco's experiments rather personal for him.
  • Big Fancy House: He owns a luxurious pad, much to Team Flash's surprise.
  • Character Development: As his bond and affection for Team Flash grows he becomes less ruthless. Except not, it's all an act. He won't hesitate to kill anyone who could possibly ruin his plans - and that includes anyone who could expose his secret identity like a certain reporter.
  • Character Tic: He has a habit of rubbing the back of his neck everytime he's talking to Gideon.
  • The Chessmaster: Barry compares him to one, accusing him of using people as pawns.
    • Later episodes show him playing chess. Hartley even compares the battle between him and Wells crew as a chess game.
  • The Corrupter: He convinces Plastique to kill General Eiling, since he'll never stop hunting her or others like her to use them as weapons.
  • Composite Character: He is a combo of the Eobard Thawne and Hunter Zolomon Reverse-Flashes. He has Zolomon's wheelchair-gimmick (though Zolomon really was crippled), plus he is a friend that Barry works with and he is clearly faster than Barry. Like Eobard Thawne, he has the knowledge of the future, scientific-ability and may very well come from the future. Both had obsessions with the Flash; Thawne was a fanboy, while Zolomon was obsessed with 'making The Flash a better hero'.
    • We later learn that he is Eobard Thawne, and he's from the future. But he's not obessed with making Barry a better hero. He's obessesed with making Barry go faster
  • Dark Is Evil: He wears an all-black outfit and is usually seen lurking from the shadows.
  • Deadpan Snarker: He occasionally throws in a snide remark. "Spoken like a true philanthropist. Or is it humanitarian? Oh, I'm sorry. I can never remember which one you're pretending to be, Simon." He can be sarcastic even about himself, as in:
    Barry: Dr. Wells, I doubt restraint is how you got to be the man you are today.
    Wells: In a wheelchair and a pariah? Lack of restraint is what made me these things.
  • Dissonant Serenity: Notice how eerily calm he is during Barry's first test run; while Cisco and Caitlin are astonished, Wells is cool and collected.
  • Does Not Like Guns: He insists that STAR Labs not make weapons and refuses to work with General Eiling.
  • Due to the Dead: He's able to recall the name of everyone who died because of the Particle Accelerator explosion.
  • Easily Forgiven: Although they call him out on it, the rest of Team Flash are pretty quick to forgive him for the things he's done (well what they know about anyway)
  • Even Evil Has Loved Ones: Subverted. He does genuinely care about Cisco (and presumably the rest of Team Flash) but he's still willing to kill them if it supports his goals.
  • Even Evil Has Standards: He's The Flash's Evil Counterpart, Reverse-Flash, but he appears to be genuinely interested in making sure that The Flash stops whatever "crisis" happens in 2024. He loses it when Barry's powers go away in "Power Outage" and his records of the future change to show that the crisis is still going on and there's no mention of The Flash anywhere. Clearly, whatever this is something so bad that even he doesn't want it to happen. Given the reveal that Wells wants to use Barry's speed to return home it may mean he was worried about being stuck in the past forever.
    • Whatever his plans may be, he considers saving Central City from an impending nuclear explosion more important.
    • He's a bit morally ambiguous or a Well-Intentioned Extremist at best, but even he's disgusted with the things General Eiling has done.
  • Evil All Along: He's the Reverse-Flash. However, it seems he's not the one who murdered Barry's first.
    • In "Out Of Time," he tells Cisco that not only did he kill Nora, he was actually gunning for Barry.
  • Evil Mentor: He's Barry's mentor; he's also the Reverse-Flash.
  • Eviler Than Thou: Leaves Wade Eiling to a vengeful Grodd once he's no longer useful.
  • Failed a Spot Check: When the Pied Piper breaks all of the glass in his house, he makes the mistake of saying he was in the middle of it, and there's not a scratch on him. Joe and Eddie then launch their own private investigation into him.
  • False Friend: To Barry since he's the Reverse-Flash. While Wells is genuinely fond of Cisco and Caitlin (although he wouldn't hesitate to kill them if they found out his secret) he wants to kill Barry. Becoming his mentor was just so he could train Barry to become fast enough that he could achieve time travel (something Wells is incapable of doing) and take Wells back to the future, then he can kill Barry.
  • Faux Affably Evil: He can be a pretty nice and chummy guy, who at first seems to be willing to give his life for his staff and Barry. Its all but an act. Best seen in "Out of Time" as Wells is shown to be deep down, one sadistic person who is willing to kill someone to uphold his secrets of being the Reverse Flash and also knowing his true of Eobard Thawne.
  • Fish out of Temporal Water: He's from several centuries in the future, and got trapped in our time after failing to kill Barry as a child.
  • For Science!: He claims his protectiveness for Barry and devotion to his cause are due to the unlimited potential for scientific advancement, especially in the field of medicine, that would come from studying him and his condition. However, when pressed he admits that it's more due to the guilt he feels over the destruction his failures wrought, and that he aids Barry to make up for what he's done. These are all lies: he's protecting Barry in order to prepare him for some kind of Crisis that will happen in the year 2024, though "Power Outage" shows that he does in fact still privately treat Barry's condition like a project, and very scientifically.
  • Genius Cripple: A brilliant scientist in a wheelchair. Except he's not really crippled.
  • Given Name Reveal: The Eobard Thawne.
  • Green-Eyed Monster: Not only is he jealous of people who are smarter than him, but he's also jealous of Barry's speed because he can't time travel and return home while Barry's speed is unlimited.
  • I Did What I Had to Do: His justification for using Tony as a distraction to Farooq.
  • Insufferable Genius: Hartley warned him there was a chance the Particle Accelerator could blow up, but he chose to ignore it. Of course he already knew that.
  • It's All About Me: He claims to want to study Barry's powers to help people, but the argument could be made that he is doing it all solely for himself, something Barry is quick to call him out on. He wants to use Barry's speed to return to the future
  • Irony: He tried to kill Barry, yet he was the one responsible for giving him his powers.
    • In "Rogue Time" he gets pissed at Barry after he uses his knowledge gained from Time Travel to undo the events of the previous episode however doing so allowed Harrison to keep his identity secret and prevented him from murdering Cisco.
  • Kick the Dog: Kills Cisco because He Knows Too Much and says that he's dead to him now.
  • Kid from the Future: He is Eddie Thawne's future relative.
  • Knife Nut: He uses a knife to murder Simon Stagg. It happens to be the signature killing style of the Reverse-Flash as well.
  • Knight Templar: It appears (as of the fourth episode), that he is absolutely determined to keep Barry Allen safe, and has no qualms about how he does so.
  • Lack of Empathy: Openly admits that he doesn't care for others after Barry accuses him of this. Iris's mentor even calls him "a sociopath."
  • Like a Son to Me: Considers Cisco this, and even tells him so, right before telefragging him.
  • Limited Wardrobe: He wears black sweatshirt, pants and sneakers every single episode.
  • Long Game: His entire scientific career was all for a purpose: become the head of S.T.A.R. Labs so he could build a Particle Accelerator that would intentionally fail so it would give Barry his super speed. And if he did murder Nora Allen, then he's been playing a very long game indeed.
  • The Lost Lenore: The sixth episode reveals Wells was once married to a fellow scientist named Tess Morgan, who died in a car accident 14 years ago (the same year Barry's mom died). Wells built the Particle Accelerator to fulfill her dreams as much as his own.
  • Love Is a Weakness:
    • Initially believes that Barry's attachment to people hold him back but then realizes, it's the opposite.
    • He does have affection for the STAR Labs Team, but he'll put aside if any of them may become a threat to his plans.
  • Manipulative Bastard: As Barry points out, Wells has no problem with controlling people and very carefully phrases everything to get the responses he desires from others.
    • As of "Out Of Time," he seems to have plunged straight into "bastard" territory, with his finally showing his hand to Cisco.
  • Meaningful Name: Harrison Wells, H. Wells, H. G. Wells. Given the revelations in "Out of Time," Eobard Thawne may well have picked this pseudonym intentionally as some sort of private joke.
  • Mind Screw: There are apparently two different Reverse-Flashes. The one on the football field is thinner than the bulky and muscular one at S.T.A.R. Labs. See for yourself. This was apparently confirmed when blood DNA indicated Wells was not the one who killed Nora.
    • This may be subverted at the end of Out of Time however when its revealed that Wells can create afterimages of himself by vibrating fast enough which he used to give himself an alibi when the Reverse-Flash was captured. He also says that he was the one who murdered Nora though whether he is telling the truth or not is debatable considering that his DNA wasn't at the house.
  • Morality Pet: Varies considerably depending on the situation. On the one hand, he does legitimately care about his S.T.A.R. Labs crew, especially Cisco, and their influence has encouraged him to act virtuously for the sake of others where he would otherwise be more ruthless and calculating. On the other hand, while he's willing to delay on their behalf to an extent, he ultimately doesn't care about them enough to let them seriously jeopardize his plans, and once Cisco discovers who he really is he murders him in cold blood.
  • Murder Is the Best Solution: His solution to any problem is always to kill. It backfires when he kills the wrong person- the reporter Mason Bridge who'd been doing a story about how Wells killed Simon Stagg. By doing so Wells inadvertently clued Barry in to his true nature.
  • My Greatest Failure: The particle accelerator quickly went from being the crowning achievement of his career to this. It's very strongly implied the whole thing was set up from the beginning to give Barry powers (with the others either being a side effect or also intentional).
  • Mysterious Past: Not much about him is known, except that he lost his wife before he moved to Central City. Given he's from the future he could either be lying or telling the truth.
  • Nothing Personal: Says this when he murders Simon Stagg to protect Barry, and even asks Stagg to forgive him. Takes this a step further with Cisco, saying that he was like a son to him and again asking his victim to forgive him.
  • Not So Above It All: A world famous scientist who eats at the Big Belly Burger at the local mall, and engages in a friendly chess game to test Barry's mind and having great fun at it. He's also a Ghostbusters fan and quotes Back to the Future.
  • Not So Stoic: Keeps a cool demeanor even when ranting but a few select phrases have a lot more emotional emphasis on them foreshadowing his true motives.
  • Obfuscating Disability: The end of the pilot shows that he lied about not being able to walk. Even his glasses appear to be unnecessary.
  • Oh, Crap: When he realizes that Barry has discovered time travel too.
  • Pet the Dog: For all his faults, he does seem to be genuinely fond of Caitlin, Cisco, and Barry. But that won't stop him from killing any of them if they stumble on to his secret
    • In "The Nuclear Man" he willingly delays his own timetable in order to save Ronnie's life.
  • Poisonous Friend: He's willing to kill Simon Stagg to keep Barry safe. Up to Eleven, in fact, as he's actually the Reverse-Flash, and has been violently preserving the Flash's future from when he was just a little kid.
  • The Sociopath: He's very manipulative, stoic, and not very empathetic. It's unclear if the affection he shows towards Caitlin, Barry, and Cisco is genuine or not.
  • Stable Time Loop: He's from the future, or has gained information from the future, where the Flash disappears. So he makes sure Barry gets his powers after engineering his entire life so that he would be in a position to get them in the first place.
  • Secret Keeper: As one of the Flash's inner circle.
  • Smart People Wear Glasses: The only one in STAR Labs with a pair, though they're all scientists or engineers.
  • Stalker Without a Crush: He's obsessed with Barry.
  • Team Dad: For the STAR Labs team.
  • The Unfettered: He will do anything to keep Barry safe, anything. He'll also do anything to keep his idenity as the Reverse-Flash a secret including nearly beating himself to death. If that was really him. Which it may not have been.
  • Token Evil Teammate: For Team Flash, Wells tends to be the one who performs, or is in support of preforming, the most morally dubious actions in order to stop the super villain of the week (such as murdering Simon Stagg in order to protect Barry's secret or telling Team Flash to kill Ronnie to prevent a nuclear meltdown) which he gets called out on a lot. Oh yeah, and he's also the Reverse-Flash.
  • Toxic Friend Influence: Sometimes he'll encourage Barry to "prioritize" and focus on enhancing his speed instead of heroics, something which Joe is highly suspicious of.
  • Trapped in the Past: He's actually from centuries in the future, and is willing to do anything to get home.
  • Walking Spoiler: As the season progresses the more that is revealed about himself the harder it becomes to talk about him without spoiling some pretty big plot twists.
  • Well-Intentioned Extremist: He sees himself this way, though it's unclear if he actually is one. He is trying to harness Barry's speed so he can go home to his time. However, the Red Sky Crisis (which will happen with or without the Flash) has yet to be fully explained; and WordOfGod has stated that Wells "is not an "evil man," and that he even has reason to see "himself as a hero." We later learn he shows disdain for Barry's time travel abilities in part because he's concerned how the time line chould change if Barry insists from deviating from established events.
  • Wild Card: On the one hand, he's done incredibly dodgy things (like murder) all in the name of protecting Barry, even though he's the Reverse-Flash. On the other hand, he seems to be genuinely fond of Barry, Cisco, and Caitlin and he's able to remember every name of all the people who died because of the Particle Accelerator and when Barry temporarily loses his powers and there are no future records of the Flash, he seriously freaks out. He's also willing to drop his wheelchair masquereade to save Barry (during a training exercise with drones it looked as Barry was about to be hit). At this point it's hard to say, what his goals are. We later learn his speed powers are in flux, and he's trying to stabilize them. He's also in some sort of alliance with Grodd. We then learn he wants to go back to the future and that Barry's speed is the key to returning.
  • Worf Had the Flu: He can use his super speed if he needs to, but it's currently in a state of flux. He's using the tachyon device stolen from Mercury Labs to fix it.

     Caitlin Snow 

Dr. Caitlin Snow

"You of all people should know that, in science, we share. We do not keep secrets.
Played By: Danielle Panabaker

A bioengineering expert who helps the Flash. Lost her fiancé in the STAR Labs particle accelerator explosion. In-universe, she first appears in an episode of Arrow set before Barry wakes up from his coma.
  • Action Survivor: Even before the show started, she and Cisco encountered Deathstroke on Arrow and survived.
  • Adaptation Dye-Job: She has brown hair in the series, instead of platinum blonde as in the comics.
  • Adaptational Heroism: In the comics, Caitlin Snow is the supervillain Killer Frost.
  • Adorkable: She complains that Operation is not anatomically correct, while playing with Barry, and then gets childishly frustrated when she touches the sides. Also, any time she talks about something scientific, she sounds like she's on a sugar high. This trope gets Turned Up to Eleven when she's drunk. She also seems to be the one to come up with the more cutesy nicknames for the metahumans they go up agaist (Rainbow Raider, Peekaboo.)
  • Aloof Dark-Haired Girl: She has a rigid demeanor since the aftermath of the Particle Accelerator accident, though it gradually disappeared since the second episode.
  • Alphabetical Theme Naming: She and Mrs. Clarissa Stein are the Love Interests of the two people that composes Firestorm.
  • Anger Born of Worry: She initially seemed constantly furious at Barry for putting himself at danger for what she saw as no good reason, but it's stated the only other person to have made her that angry was her late fiancee, suggesting she cares about him more than she lets on. As they grow closer, she starts displaying less anger and more genuine concern.
  • Brainy Brunette: She's a brilliant bioengineer who, unlike the comics, has brown hair.
  • Brutal Honesty: She doesn't bother lying to Barry about how the needle she's going to jam in his chest will hurt a lot.
  • Composite Character: She's a S.T.A.R. Labs scientist like the third Killer Frost, from whom she also takes her name, but her romantic backstory with a character who becomes Firestorm is incorporated from Crystal Frost, the first Killer Frost.
  • Defrosting Ice Queen: Barry notes in the Pilot that she doesn't smile much. Justified, in that the particle accelerator accident killed her fiance and destroyed her career. However helping Barry with his heroics is bringing her out of her shell, she's actually enjoying herself by the end of the second episode.
  • Heterosexual Life-Partners: With Felicity Smoak.
  • Hospital Hottie: A very attractive young woman who acts as Barry's physician after the lightning bolt changes his physiology.
  • Hot Scientist: As noted in the above trope, an attractive woman who's studying the explosion's effects on the metahumans, especially Barry.
  • Hypocritical Heartwarming: She tells Barry that "she won't patch him up every time he breaks something." Then she does.
  • The Medic: To the Flash.
  • Married to the Job: Everyone notices she has very little life outside of her job. It's partly because she's naturally a workaholic (her fiancee was the one who got her to relax) and partly because she's working to forget about Ronnie.
  • Morality Chain: For Ronnie when he was still unwillingly fused with Prof. Stein, much like how his wife Clarissa was for the latter during the ordeal.
  • Mythology Gag: She mentions Ronnie used to say they were "fire and ice", a nod to her alter-ego in the comics, ice-based villain Killer Frost. In "Flash vs Arrow" she also wears a necklace with the cold front weather symbol.
  • Not So Stoic: When she sees what Barry can do, she just gapes in amazement. She's also worried about Barry during his first major fight as the Flash.
  • Oh, Crap: When she realizes that Wells is the Reverse-Flash. However, she forgets when Barry hits the Reset Button.
  • Platonic Life Partners: With Cisco. When Ronnie appears to her he is the first person, not Barry, nor Doctor Wells, she tells about it.
  • Red Oni, Blue Oni: With her stern and introverted demeanor, she's blue to Cisco's red.
  • Refusal of the Call: At first, she doesn't approve of Barry using his powers to help ordinary citizens, instead thinking they should be used exclusively to contain rogue meta-humans. She changes her tune by the end of the second episode though.
  • She Cleans Up Nicely: Barry was quite surprised that she showed up to their Not a Date in a Little Black Dress. Caitlyn mentions that she doesn't dress up like a school principal every day.
  • Secret Keeper: Another one of the Flash's inner circle.
  • Ship Tease:
    • With Barry, considering the only person to make her as angry as Barry does was her late fiancee. He also gets her to smile.
    • In Things You Can't Outrun, they spend a good deal of time together, and he helps her with panic attacks provoked by the thought of the Particle Accelerator. The comic tie-in implies that she's attracted to him.
    • In Power Outage, she specifically compares him to Ronnie, saying she doesn't want to lose anyone else she cares about.
    • In Crazy for You, a large part of the episode is devoted to Barry & Caitlin's relationship; most of it serves to make sure the audience knows there's some sort of attraction. Or, at least that Caitlin is attracted to Barry. Barry, apparently, is completely oblivious.
  • The Stoic: Ever since the explosion killed her fiancé and ruined her career, she's been very detached. Until she meets Barry, at least.
  • Undying Loyalty: Even though the explosion ruined her career and killed her fiance, she's still working for Dr. Wells and STAR Labs.
  • When She Smiles: Despite her rigid demeanor, she smiles ear to ear when Barry defeats Clyde Mardon and comes out okay. By the time of Episode Two, she is smiling whenever she knows she's helping the Flash in general.

     Cisco Ramon 

Cisco Ramon

"This just keeps getting cooler!"
Played By: Carlos Valdes

A mechanical engineering genius who helps the Flash. In-universe, he first appears in an episode of Arrow set before Barry wakes up from his coma.
  • Action Survivor: Even before the show started, he and Caitlin encountered Deathstroke on Arrow and survived.
  • Adaptational Wimp: Ultimately subverted. At first he is presented as the show's Plucky Comic Relief despite being a superhero in the comics. It is later revealed that he has combat training as shown in his fight with Hartley.
  • Adorkable: He's not unlike Barry in this aspect.
  • Audience Surrogate: For the fanboys in the audience, certainly. He is the one who's the most excited by Barry's powers, and came up with the idea of Barry wearing a special suit. The lightning bolt logo was also his idea. He also gives the metahuman criminals their super-villain names.
  • Berserk Button: Destroying his tech. He was downright furious when he heard Bette had blown up (accidentally) Barry's suit, or at least until he saw how attractive Bette was.
  • Break the Cutie: Besides his death at the hands of Wells he is captured by the Rogues and forced to build weapons for them or else Captain Cold would kill his brother.
  • Crazy-Prepared: After the explosion at STAR Labs, he's become this by nature and necessity. Once he developed a perfect suit to handle Barry's capabilities, he made three. Regardless of how much sense his over-preparedness makes sense, it's gotten him in trouble with Dr. Wells, who is angered that Cisco created a weapon to counter Barry's capabilities out of worry that Barry may turn against them one day.
    • Zigzagged all around. Cisco is great about building things he needs - a Flash suit, an anti-Flash gun (that they actually could have used when Barry got hit with a Hate Plague), a sonic device to control Hartley, he even came up with the idea to hold metahumans in the reactor. But he's extremely careless with his tech meaning that it often gets used against him.
  • Distracted by the Sexy: Although he's initially enraged by Plastique destroying Barry's suit he drops it immediately when he gets a look at her.
  • Everyone Has Standards: Draws the line at Caitlin's suggestion of "Rainbow Raider".
  • Face Death with Dignity: He manages to stand his ground calmly as Wells prepares to scramble his insides, despite still reeling from learning the truth.
  • Gadgeteer Genius: Designs the Flash's suit, and outright admits his job at STAR Labs is to "make the toys", which includes anti-Flash weaponry as "Going Rogue" shows.
  • Fun T-Shirt: He wears a lot of these.
  • He Knows Too Much: Why Wells kills him.
  • Idiot Ball: He built a freeze ray to counter Barry's speed if he ever went rogue, which is not an unreasonable suspicion considering what the other meta-humans are like. The only problem is he didn't tell anyone else about it, and carelessly put it in a cheap locker, which was easy to break in to. It then gets stolen by Captain Cold's paid-off janitor at S.T.A.R. Labs.
    • Cisco gets handed the ball a lot. He also let Hartley out of his cell, letting him escape.
  • Jumped at the Call: The first of the S.T.A.R. Labs team to help Barry with his heroics, including the ones not involving meta-humans.
  • Keet: Even Barry is calm and collected by comparison.
  • Killed to Uphold the Masquerade: Poor Cisco gets impaled by Wells after he discovers the good doctors true identity. Though considering the fact that this is a comic book show and Barry can travel though time now its probably not going to stick.
  • Minored in Asskicking: Mostly works as the team's Gadgeteer Genius but, as his fight with Hartley Rathaway shows, he can put up a fight if he needs to.
  • Motor Mouth: When he is talking about something he likes, he tends to go into vivid or so detail.
  • The Movie Buff/TV Genius: If a Shout-Out to a movie or/and a TV show is going to be made, it's usually him who does it.
  • Mythology Gag: Cisco Ramon is the name of the superhero Vibe. He later tells Hartley "You're not the only one who understands vibrations", while using a sound-based weapon against him.
  • Nice Guy: Out of all the S.T.A.R. Lab team, he's the one who's more interested in helping Barry adjust to his new life instead of treating him as walking lab experiment.
  • Nice Job Breaking It, Hero: He was the one who designed Leonard Snart's cold gun, and kept it in a rinkydink little locker where it inevitably got stolen.
  • The Nicknamer: He comes up with the names for the meta-human Flash fights, and is very territorial about it.
    Hartley: I was thinking of calling myself Pied Piper.
    Cisco: Hey, I assign the nicknames around here! ...Although that one's not bad.
  • No One Gets Left Behind: Shows this attitude, and was very reluctant to leave Ronnie behind in the particle accelerator as well as leaving Wells to deal with Farooq.
  • Person as Verb: A specially modified treadmill is "Ciscoed", coined by himself.
  • Precision F-Strike: Not literally, but his tendency to frequently call Hartley Rathaway "a dick" is still the saltiest language the show uses.
  • Platonic Life Partners: With Caitlin. When Ronnie first appears to her he is the first person she tells about it. He is immediately supportive despite not being completely sure she actually saw him.
  • Red Oni, Blue Oni: With his cheery and enthusiastic demeanor, he's red to Caitlin's blue.
  • Secret Keeper: As one of the Flash's inner circle. However, he tells Captain Cold when presented with a Sadistic Choice.
    • Even though he had a falling out with Joe since the latter accused Dr. Wells of having been involved in Nora Allen's murder, Cisco still runs the blood tests and calls Joe about the results, making sure Wells is out of earshot first.
  • Slobs Vs Snobs: His conflict with Hartley. Hartley couldn't believe someone like Cisco could be a mechanical genius.
  • Stepford Smiler:
    • He may act cheerful and goofy, but he harbors deep feelings of guilt for locking Ronnie in the particle accelerator (at Ronnie's own insistence, to channel the impending explosion and protect as many people as possible).
    • He's also enstranged from his family, which is why he relies on the rest of Team Flash for emotional support.
  • Survivors Guilt: Dude has some serious issues and insecurities left from locking Ronnie in the particle accelerator. Which is why, when Ronnie comes back, Cisco is so adamant on finding him.
  • Sweet Tooth: He's constantly snacking on candy and other sugary foods.
  • Totally Radical: Likes to talk jive. Caitlin lampshades this in Arrow.
    Cisco: I hereby christen this building the bomb.
    Caitlin: Nobody says that anymore.
  • Two First Names: Being a DC Comics based character, he has a last name that is traditionally used as a first name.
  • Undying Loyalty: He's still working for STAR Labs and Dr. Wells after the explosion. He even originally built the Flash suit for firefighters, in the hopes the city would stop hating Dr. Wells.
  • The Unfavorite: Despite his genius, his parents treat his older brother with more love and attention.
  • "Well Done, Son!" Guy: Less of a father-son way and more of a hero-employee way. Cisco craves Wells' approval, as pointed out by Pied Piper. Ironically enough Wells says he considers Cisco to be the son he never had... before killing him.

     Iris West 

Iris West

"We grew up one bedroom down from each other, do you honestly think I don't know when you're happy, or sad, or depressed, or lost?"
Played By: Candice Patton

A grad student who's friends with Barry.
  • Adaptation Dye-Job: Her comic counterpart is a classic example of Heroes Want Redheads. Became a brunette for the show to accommodate her Race Lift.
  • Action Girl: In The Flash is Born, she's the one that lays out the Villain of the Week when he tries to get up after the Flash hits him with a Supersonic Punch. In Power Outage, she rescues herself after being taken hostage by Clock King by surprise-shooting him with Eddie's gun.
  • Big Damn Kiss: Finally kisses Barry when they try to rescue Joe, but Barry's discovery of time travel at the end of the episode erases this.
  • Brainy Brunette: She's a graduate student studying criminal psychology.
  • Childhood Friends: With Barry. They have been friends since they were kids.
  • Damsel out of Distress: Twice now, a bad guy tried to take her hostage. Twice now, it didn't turn out quite as they expected.
  • Dating What Daddy Hates: Initially she wanted to be a cop; her cop father said no, on the grounds that a life in the police force would be too dangerous. She's currently dating Detective Thawne in secret. It's no longer secret as of "Things You Can't Outrun".
  • Fun Personified: Iris is very upbeat and affirming of others, she doesn't like journalism until she finds a story she cares about, at which point she dives in headfirst.
  • Genki Girl: Iris comes off as a bit on the bubbly, enthusiastic and hyper side.
  • Hot Scoop/Intrepid Reporter: Well, Iris is a journalist student and blogger.
    • When she gets a proper job at newspapers, she agrees to look into the going ons of her friends at STAR Labs.
  • Like Brother and Sister: How she views Barry, since her father took him in after his father was convicted of murdering his mother.
  • Locked Out of the Loop: Joe made Barry promise that he wouldn't tell Iris about his powers, something he's not very happy about.
  • Missing Mom: We have yet to see any sign of her mother, which is significant because her father is a major character. Flashbacks show that this was the case back when she was eleven.
  • Motor Mouth: Has her moments.
    Wells: She [Iris] came to see you [Barry] quite often.
    Caitlin: She talks a lot.
  • Nice Girl: For the most part, she's pretty sweet.
  • Oblivious to Love: Until he point-blank tells her about it, she has no idea that Barry's feelings for her have developed beyond the above even though Barry isn't very good at hiding it. It's also interesting that she keeps talking about how no other woman else seems to be able to see how amazing he is, which means she might be oblivious to her own feelings.
  • Platonic Life Partners: With Barry since they were kids. However, the feelings on Barry's side have become more than platonic.
  • Race Lift: She's white in the comics, but black in the show.
  • Shipper on Deck: For Barry and Felicity.
  • The Smart Girl: Iris is a Brainy Brunette who has shown that she has brains and intelligence.

     Joe West 

Detective Joe West

"I've always had a simple set of beliefs. Until a few weeks ago, I believed the fastest man could run a mile in four minutes — not four seconds."
Played By: Jesse L. Martin

A detective in the Central City PD and Iris' father.
  • Adaptational Heroism: The New 52 version of the West patriarch was an Abusive Parent, enough that his own son Daniel crippled him in an attempt to end his life. Joe West however is a good man and a great father (and father-figure) to both his daughter and his foster son... Of course, the pre-Flashpoint version was also a likeable person, so it's subverted on that count.
  • Adaptation Name Change: Was named Ira (New Earth) or William (Prime Earth) in the comics.
  • Agent Scully: Doesn't take much stock in Barry's more "creative" theories. Until he sees Barry and Mardon fight, that is. Even after that he's still sceptical about the Man In Yellow until he actually sees him.
  • Arch-Enemy: He's been chasing the Mardon brothers for a long time, and it just got personal when his partner was killed.
  • Badass Normal: A veteran detective, he is still skilled enough to go against metahuman threats like if they were normal everyday crooks. Notably he's the first one to guess that there's more to Dr. Wells than meets the eye.
  • Composite Character: He is actually much more similar to the New 52 version of Darryl Frye than to any version of the West father (who originally was a scientist who designed his special suit, much like the S.T.A.R. Labs crew in the show).
    • His adopting of Barry after his mother's murder and father's arrest is taken from New Earth's Ira West, who is the adoptive father of Iris (who in that version of the story was born in the 30th century).
  • Deadpan Snarker: As evidenced by his Shut Up, Hannibal! moment with Clyde Mardon.
    Joe: Why in the hell would God need to rob banks?!
  • Fantasy-Forbidding Father: He tries to get Barry to stop his extra-curricular heroics, but he eventually relents when he realizes how much the city needs Barry.
  • Friend on the Force: To S.T.A.R. Labs
  • Good Parents: Really, we shouldn't have to explain this one. Just look at this page and check how many Joe moments are on there.
  • Hidden Depths: He was able to name each of the people that coined the quotes Clock King was reciting.
  • Horrible Judge of Character: Notably one of the few characters to avert this as he is the first to suspect Wells. It's due to him being an experienced detective able to notice small details and be Properly Paranoid while the rest of the characters are Naive Newcomers who trust a bit too easily.
  • Lawyer-Friendly Cameo: Not that dissimilar from Law & Order's Ed Green, even down to the same actor. Which is interesting, since Green and his partner Joe Fontana had a cameo in a Batman comic.
  • Like a Son to Me: He raised Barry like his own son, and he considers him as such, casually referring to him as "my kid" a couple of times.
  • Not So Above It All: He's usually stern and the Only Sane Man, but when Barry shows him he can vibrate his vocal chords to throw his voice, he can't help but geek out.
  • Overprotective Dad: He tends to treat Iris and Barry like the're still a couple of ten year olds, instead of young adults. He scolds Iris and Barry, after the two of them were nearly caught up in a robbery and refused to let Iris follow in his footstep as a cop.
    Joe: You're just a kid. You're my kid.
  • Parental Substitute: Took Barry in after his dad went to jail, and will occasionally refer to him as "son" or "my kid" without even thinking about it.
  • Parents as People: Joe genuinely loves Iris and Barry and does his best to help them and keep them safe but this is offset by flaws in his own character such as being stubborn in the face problems where he has to relent, Because I Said So tendencies that are invalidated by his lack of ability to enforce his statements, and some Innocently Insensitive moments that show with Barry.
  • Police Are Useless: Joe utterly subverts this, which is borderline unheard-of in superhero media. Even meta-human threats, which you could excuse normal police from being able to handle, are all but another day on the job for Joe West.
  • Race Lift: He's white in the comics, but black in the show.
  • Secret Keeper: The only one outside STAR Labs and Team Arrow who knows about Barry's powers.
  • Shipper on Deck: For Barry and Iris as revealed in "Plastique."
  • Skeptic No Longer: He doesn't believe Barry until he sees that Clyde Mardon is alive and can control the weather, and that Barry can run fast enough to unravel a potential F-5 class tornado.
  • That One Case:
    • Nora Allen's murder. A murder that ruined the lives of his friends, resulting in him effectively adopting their child? Yes.
    • Also, the Mardon brothers' case.

     Eddie Thawne 

Detective Eddie Thawne

"Freeze, police! Or do you want to find out the hard way you're not faster than a bullet?"
Played By: Rick Cosnett

A police officer in the Central City PD, recently transferred from Keystone City, who becomes Joe's partner and Iris's boyfriend.
  • The Ace: He's great at his job to the point of having started to keep scores of his arrests.
  • Adorkable: Mostly when it comes to talking to his partner about the fact that he's dating his daughter.
  • Always Someone Better: To Barry (whenever he's in civvies anyway). Most obvious when he catches a bag-snatcher that had, just a few moments ago, knocked Barry flat on his rear. Then he starts dating Iris.
  • Big Damn Heroes: He leaps into action to save the Flash in a crucial moment during his fight against Captain Cold and Heat Wave.
  • Can't Kill You, Still Need You: The only reason he was spared by the Reverse-Flash is because he is Thawne's distant relative.
  • Cop Boyfriend: To Iris.
  • Fair Cop: We will be mentioning his nickname "Detective Pretty Boy" several times.
  • Formerly Fat: He used to be a short, fat kid, who was teased a lot.
  • Green-Eyed Monster: Admitted to Barry that he was a bit jealous of his relationship to Iris, but he gets over it and bonds with him over the Tony Woodward case. It does briefly pop up again when Barry gives Iris a replica of her mom's wedding ring
    • He initially did not like the Flash at all, and considered him a threat on little or no evidence mainly because Iris liked him. However, he got better after the Flash helped the police against Reverse-Flash, and is a full-on Flash supporter by Revenge of the Rogues.
  • In-Series Nickname: Detective Pretty Boy.
  • Mysterious Past: His past is described as a mystery and harbors a dark secret according to Word of God.
    • He's mentioned a little bit to Barry in "The Flash is Born." He said he was a short, fat kid who's dad was a local politician who shut down the factory in his school district, meaning he got his ass kicked. A lot.
  • Mythology Gag: His name is a reference to the comics character Eobard Thawne, known to be Professor Zoom/Reverse-Flash in the comics. However, he proves to be a Red Herring for Harrison Wells, the true Eobard Thawne/Reverse-Flash. Wells, however, calls Eddie a "distant relative," which may mean that Eddie is his direct ancestor.
  • Nice Guy: So far, he has been seen to be very affable and friendly to Joe and Barry, always showing concern and empathy for Barry.
  • Not So Different: As he points out to Barry, they're much more similar than he thinks: both had rough childhoolds, were tormented by bullies, frequently got their asses handed to them, and eventually grew up to help people in the CCPD.
  • Open Mouth, Insert Foot: He's this around Joe on matters about him being Iris's boyfriend.
  • Pop-Culture Isolation: An in-universe example. During a pub quiz, Eddie apparently didn't know the name of Han Solo's ship.
  • Pretty Boy: To the point of being nicknamed Detective Pretty Boy in-universe. Even Caitlin thinks he's hot.
  • Red Herring: Despite sharing a surname with comics character Eobard Thawne and having being suspiciously spared by the Reverse-Flash, he is not Reverse-Flash; Wells is. This is turned Up to Eleven in Out of Time, when Wells is revealed to be Eobard Thawne himself.
  • Secret Keeper: Let in on the meta-human secret, though Joe still keeps Eddie in the dark in regards to Flash's secret identity.
    • He's also the only one on the police force that knows that Joe is investigating Harrison Wells.
  • Stop or I Will Shoot!: "You're not faster than a bullet." (Said to a crook, not the Flash.)
  • Sympathetic Inspector Antagonist: Created a task force to catch Flash (who had violently assaulted him earlier) before becoming his loyal supporter.
  • Took a Level in Kindness: In the first episodes, he seemed to be a little more of a cocky jerk (keeping count of his arrests, being overly proud of catching a mugger, etc.) However, a few episodes in, that phases out and he starts to become friendlier and nicer. Compare and contrast both times Barry compliments him for "saving the day" when the Flash was present — the first time, in Fastest Man Alive, he brushes it off with faux humbleness, but gives credit to no one else; the second time, in Revenge of the Rogues, he gratefully thanks the Flash for everything.
  • What the Hell, Hero?: Punches Barry for trying to steal his girlfriend. However, he later apologizes to him when Caitlin explains that it was part of his medical condition.

Supporting Characters



  • 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".
  • 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 Fiirestorm 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.
  • Flying Firepower: He can also fly.
  • Fire-Forged Friends: Both literally and figuratively. The Flash himself count as a figurative example.
  • Fusion Dance: An unintentional one the night of the explosion. 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".
  • MacGuffin Girl: 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.
  • 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, they both feel when other is in great distress or pain.
  • Wreathed in Flames: When he first uses his powers on-screen. In fact, in general whenever he uses his powers.

Ronald "Ronnie" Raymond

Played By: Robbie Amell

Caitlin's deceased fiancé, and the head engineer for the particle accelerator. He died the night it malfunctioned, giving his life in order to prevent the entire building from being destroyed. Or so it seemed.
  • Age Lift: Ronnie is traditionally a teenager when he becomes the superhero Firestorm; here, he's roughly in his mid-to-late twenties.
  • Alliterative Name: Ronnie Raymond.
  • And I Must Scream: how he describes his initial situation with Stein. Cisco asks him what it's like to have those powers, except Ronnie complains that he'd be enjoying every minute of it, if he were actually in control.
  • Came Back Wrong: Seems so at first, though it's eventually revealed it's actually Martin Stein in Ronnie's body.
  • Cynicism Catalyst: For Caitlin.
  • Do Not Call Me Paul: Does not like being called Ronald.
  • Heroic Sacrifice: He went inside the accelerator in order to manually redirect the explosion, and made Cisco close the blast doors in two minutes in case he didn't get back in time. He didn't make it back in time.
  • Hot Scientist: He's smart enough at engineering to help design the accelerator. He's also extremely attractive. Not so much immediately after coming back, but He Cleans Up Nicely again by "The Nuclear Man".
  • Looks Like Jesus: After he Came Back Wrong.
  • Never Found the Body: A given, since he was vaporized by the particle accelerator explosion. Except he wasn't; The Stinger for "Flash vs. Arrow" reveals that he's still alive, and acquired the abilities of his comics counterpart.
  • Opposites Attract: He was warm and jolly, she was cool and logical. They brought out each other's best, and he even referred to the two of them as "fire and ice".
  • Posthumous Character: Killed in the accelerator explosion. Psych — he actually survived and has become a metahuman.
  • Secret Keeper: Upon being calmed down shortly before his and Prof. Stein's initial separation, he/they becomes aware of Barry's identity as The Flash.
  • Tall, Dark and Handsome: He's 5'11.
  • Trademark Favorite Food: More than a few jokes are made about his love for pizza.
  • Two First Names: Being a DC Comics based character, he has a last name that is traditionally used as a first name.
  • Walking Spoiler: Thanks to his reappearance in the ninth episode (and The Stinger of the eighth episode).

Professor Martin Stein

Played By: Victor Garber, Robbie Amell

The creator of Project F.I.R.E.S.T.O.R.M., who has something to do with what happened to Ronnie.
  • Adorkable: Just watch him excitedly ramble on about time travel.
  • Chekhov M.I.A.: He's first introduced having already gone missing, after heading off to confront the person who shut down his work. Whoever it was must have worked at S.T.A.R. Labs, as he was there the night of the explosion and was fused with Ronnie.
  • Cool Old Guy: Gives Barry advice about his love life.
  • Deadpan Snarker: Quite a bit, mostly about the crew discussing things loudly.
  • Heroic Suicide: He tries to kill himself in Ronnie's body so it will not go nuclear and kill everyone.
  • Hippie Teacher: Though we've yet to see him teach a class, he is a professor and he did protest the Vietnam War in college.
  • Intergenerational Friendship: Hits it off pretty fast with most of Team Flash, especially Barry.
  • Married to the Job: Before the reactor explosion, he was more interested in his research than his wife, to his regret.
  • Mad Scientist: He was messing around with molecular transmutation, on a project whose name Ronnie gives Caitlin as the only clue for what made him a meta-human.
    • Subverts this in that he realizes the potential for his research to be misused.
  • Trademark Favorite Food: Has learned to love pizza due to being fused with Ronnie for 14 months. He hated it before.

     David Singh 

Captain David Singh

Played By: Patrick Sabongui

The captain of the police precinct where Joe and Barry work at.
  • A Father to His Men: Despite all of his bluster at the end of the day its revealed that Singh genuinely cares for his men, he's still torn up over Detective Chyre's death in the pilot, he willingly jumps in the way of a lightning bolt to save Joe's life and, according to his fiancé genuinely praises Barry's skills.
  • Badass Gay: He is Da Chief of the CCPD, after all.
  • Career-Ending Injury: After Taking the Bullet for Joe, his doctor claims that he may never go back to active service again. Thankfully negated by Barry's Time Travel.
  • Da Chief: Repeatedly annoyed by Barry's habitual lateness to crime scenes and Joe's attempts to cover for him.
  • Good Is Not Nice: He's on the side of the good guys, but he's not exactly the nicest of supervisors.
  • Heroic Sacrifice: He jumps in the way of an incoming lightning bolt send by Mark Mardon to kill Joe and saves the latter's life. While the bolt doesn't kill him it did do significant internal damage to his body, giving him possible brain damage and possibly crippling him as well - before Barry's time-travelling at the end of the episode prevented the event, that is.
  • Jerk with a Heart of Gold: Despite acting like a bit of a Jerkass throughout the majority of his initial appearances, "Out of Time" reveals that when it gets down to it he genuinely does care about his men. When Mark Mardon appears, and threatens to murder Joe for the death of his brother, Singh tells Joe in no uncertain terms that he will not allow him to die like his partner did. And later when Mardon attacks the police station he jumps in the way of a lightning bolt aimed for Joe. His fiancée even mentions that he's all bark.
  • Reasonable Authority Figure: Although he's exasperated by Barry's perpetual tardiness, he's also aware that he's very good at his job.
  • Straight Gay: Revealed to be one in Episode 8. He references his boyfriend in passing. As of Out of Time its been revealed that he is now Singh's fiancé and we actually get to meet him.

     Henry Allen 

Dr. Henry Allen

Played By: John Wesley Shipp

Barry Allen's father, a physician who is doing a life sentence in Iron Heights Prison for the murder of Barry's mother Nora.
  • Clear My Name: Barry is determined to do this for Henry, though Henry would rather he not and just live his own life.
  • Deadpan Snarker: Has an amusingly droll sense of humor, being content with his current situation.
  • Disappeared Dad: In prison since Barry's childhood.
  • Good Parents: Even though he's not in Barry's life for obvious reasons, it's quite clear he's a loving and caring father. To the point he doesn't want his son to sacrifice his own life and opportunities in trying to clear his name; he even (initially) told Joe to prevent Barry seeing him for his son's sake, a questionable action but done out of love.
  • Mistaken for Murderer: The very reason why he is locked up, as well as his son's motivation/drive to clear his name.
  • Not Helping Your Case: He picked up the knife that was used to kill Nora, so he could try to stabilize her heart. Unfortunately, leaving his fingerprints on the murder weapon gave the cops other ideas.....
  • Remake Cameo: John Wesley Shipp played Barry Allen in the previous Flash TV series.
  • The Scapegoat: He was essentially framed by the Reverse-Flash for the murder of his wife.
  • Secret Secret Keeper: He figured out Barry was the Flash after seeing him save Joe and after he broke out a mob henchman (who stabbed him) to be interrogated, but doesn't stated it directly.
  • So Proud of You: In Crazy For You Henry makes it clear he knows Barry is the Flash, and he's damn proud of the hero his son has become.
  • Two First Names: Being a DC Comics based character, he has a last name that is traditionally used as a first name.

     Linda Park 

Linda Park

Played By: Malese Jow

A sports journalist for Central City Picture News, formerly reporting for KSFZ Channel 8. First seen reporting at S.T.A.R. Labs the night the particle reactor was being turned on, she become acquainted with Barry Allen a year later when he and Caitlin were drunkly singing karaoke at a bar.
  • Adaptation Distillation: In the comics she's a love interest to Wally West, not Barry.
  • Age Lift: In the comics she's of a similar age to Iris's nephew Wally, while in the show she's the same age as Barry and Iris.
  • Early-Bird Cameo: She first appears (played by a different actress) in "Three Ghosts" over at Arrow, reporting as the particle accelerator malfunctioned. This footage of her was reused for the pilot.
  • Hot Scoop: Enough to get Barry interested at her.
  • I Want My Beloved to Be Happy: Upon realizing Barry's feelings for Iris, she tells him to go for it without any kind of drama.
  • The Lad-ette: During their first date, she and Barry have a contest to see who can handle spicy foods the best. She wins.
  • Locked Out of the Loop: She doesn't know Barry is the Flash, so it causes some friction when his duties with the Flash interfere with their time together.
  • Promoted to Love Interest: Played with. She is a Flash Love Interest, but for Wally West not Barry Allen.
  • Romantic False Lead: Unsurprisingly, she was this for Barry.
  • Second Love: Barry is mesmerized by her after spending so many years pining for Iris.

     Mason Bridge 

Mason Bridge

Played By: Roger Howarth

A Pulitzer Prize winning journalist who is mentoring Iris. He is suspicious of Wells and has been investigating him


     The Reverse-Flash 

The Reverse-Flash

"We've been at this a long time, you and I. But I'm always one step ahead." (Click to see him unmasked - SPOILERS!) 

A mysterious man wearing a yellow version of the Flash's suit and apparently having the same super speed abilities. He murdered Nora Allen for unknown reasons. He's also been dubbed "the Man in a Ball of Lightning" and "the Man in the Yellow Suit". His true identity remains unknown. After Barry got his powers, he and Joe reopened Nora's case, hoping to bring her killer to justice and free Henry. But unknown to Barry, he's still in Central City and keeping a close eye on Barry's loved ones.
  • Affably Evil: Even when he is secretly manipulating Barry, Caitlin, and Cisco to serve his ultimate goals, he admits to Cisco (in a previous timeline), that he does care for them somewhat right before he kills him.
  • Ambiguously Human: Gives off this vibe. He certainly looks like a man, but he's also constantly vibrating in an unstable manner, has glowing red eyes, claims to have goals beyond the understanding of normal humans, and in general gives off a feeling unnaturalness. invoked
  • Arch-Enemy: He claims that he and Barry have already been at this for a long time, and given his actions so far, not to mention his Evil Counterpart nature, he does seem meant to be this for the poor guy.
  • Badass: Hey if you're going to be the Flash's Arch-Enemy you have to be. In both fight's he's been in with Barry he effortlessly manages to kick the crap out of him without even trying and the only reason he doesn't kill him right there and then is because of Firestorm's intervention.
  • The Bad Guy Wins: In The Man In The Yellow Suit the Reverse-Flash manages to steal the Tachyon Device and brutally beat up Barry before he leaves.
  • Because Destiny Says So: During his first fight with Barry, he taunts the poor guy with lines like this, claiming that Barry is destined to lose and that Nora was destined to die by his hand. It's unknown if he actually believes this or if he was just using the idea to Kick the Dog.
  • Bigger Bad: He killed Barry's mother, which kick-started the events of the entire series. But so far he doesn't show himself much. That's because Wells' powers are in a state of flux.
  • Clark Kenting: Averted big-time; he vibrates his face and vocal chords just like Barry, and the blazing red eyes don't hurt, either.
  • Composite Character: Though it may be too early to tell, this character seems to share the look and background of Eobard Thawne/Professor Zoom (murdered Barry's mother, most definitely has Super Speed) but the motives of Hunter Zolomon/Zoom (he makes several statements that makes it seem as if his ultimate goal is to perfect the Flash, and if his identity as Harrison is any indicator, he's willing to go VERY far to help the Flash). Plus, he possesses Zoom's red eyes instead of Professor Zoom's golden ones.
  • Curb-Stomp Battle: Both of his first two fights with the Flash go very heavily in his own favor and leave Barry badly shaken.
  • Evil Counterpart: To the Flash. While Barry uses his power to help others and save lives, the Reverse-Flash uses his powers to scare the hell out of people and kill them.
    Dr. Wells: ...Your powers are almost exactly like those of the Flash!
    Reverse-Flash: Oh, I'm not like the Flash at all. Some would say I'm the reverse.
  • Evil Sounds Deep/Voice of the Legion: He vibrates his vocal cords in order to distort his true voice, just like Barry. Unlike Barry, however, he sounds like a demon straight out of Hell when speaking.
  • Evil Plan: He wants to get back to his own time, but his powers just aren't fast or stable enough, so he plans to use Barry's speed instead.
  • Glowing Eyes of Doom: Those eyes are scary.
  • Good Colors, Evil Colors: His suit is literally an inverse of the Flash costume, and he leaves a trail of red lightning rather than gold when he super-speeds.
  • Hell Is That Noise: Twice he's sounded off a bloodcurdling screech when present.
  • Hidden Villain: Nobody knows who he is or what he's truly up to, and he wants it to stay that way. When he somehow finds out that Joe is reinvestigating Nora's murder and is actively looking for him, he wrecks his living room like he did the night of Nora's murder, steals the case file and puts a knife through a picture of Iris as a warning to drop the case. When he finally shows up in the flesh, he keeps not just his face but his whole body blurred and disguises his voice to prevent anyone from deducing his true identity.
  • Kick the Son of a Bitch: Leaving Eiling at the mercy of Grodd.
  • Kill the Cutie: And then he had to go and kill Cisco.
  • Knife Nut: He murdered Nora Allen with a knife to her heart, and puts one through a picture of Iris as a threat to Joe to drop the case.
  • Knightof Cerebus: The Flash is generally a show with a light tone. However, things get darker when the Reverse-Flash shows up.
  • Know When to Fold 'Em: After already getting what he came to steal, he has no problem staying to kick the Flash's ass, but as soon as Firestorm shows up, he bails out at full speed.
  • Leitmotif: Fittingly for an Evil Counterpart, he has one that's basically a Darker and Edgier version of the Flash's theme, punctuated by a helicopter-like percussion pounding.
  • Light Is Not Good: As is tradition with the character, he wears a yellow suit (though with more black on it than the comic book version) and is the Flash's archenemy.
  • Lightning Bruiser: Puns aside, he is faster and notably a lot stronger than Barry. Barry himself even mentions this after his first fight with him.
    Barry: I'm not the fastest man alive anymore, he is!
  • Meaningful Name: Aside from being his Evil Counterpart, his costume is an inverse of Barry's Flash costume.
  • Mysterious Past: We have no idea if he got his powers during the Particle Accelerator explosion or before. But we do know that he's still in Central City and is keeping an eye on the Flash and those close to him.
  • Nightmare Fuel: In-Universe, he's this for Barry. With good reason, as he killed Barry's mom. To add to this, he's an unrepentant murderer who can move at the speed of sound. As Barry pointed out, he could kill everyone in the police station in seconds. He also knows who Barry is and who his loved ones are.
  • Power Incontinence: Wells' powers are in a constant state of flux they come and go. The reason he stole the tachyon was to help get his powers to stabilize, and even then he knew it would only be patch job fix.
  • The Reveal: He's Harrison Wells. It is, however, worth noting that the two were face-to-face with each other in one scene and acts very different from one scene to another, implying that there might be more than one Reverse-Flash.
    • "The Nuclear Man" confirmed there were two speedsters at Nora's murder. Additionally, they found blood spatter from both of them and thanks to DNA typing: One was an adult Barry. The other was unidentified, but since Cisco specifically checked against known samples, it was initially believed to not be Wells, but...
    • "Out of Time" is a real Wham Episode. His real name is Eobard Thawne (he describes Eddie as a distant relative). Wells really was at Barry's house that night, except that he wasn't there to kill Nora, he was there to kill Barry. Reverse-Flash beating up Wells? A speed mirage to keep his cover.
  • Vibro Weapon: He can vibrate his arm through people in order to kill them. He offs Cisco in a previous timeline and Mason Bridge in the current one this way.
  • Would Hurt a Child: Why was he at the Allen house that night? He was there to kill eight-year-old Barry; Nora evidently just got in the way.

     Clyde Mardon 

Clyde Mardon

Played By: Chad Rook

A criminal who gains powers 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 weather powers in the comics; Mark, his brother, does.
  • 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 is the Weather Wizard and the first villain to be faced by the Flash. While he does die at the end of his attempted attack on Central City, it's undeniable that he had a rather larger role before that in this incarnation.
  • 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.
  • 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.
  • Blond Guys Are Evil: The first supervillain to hit Central City, sporting blond hair.
  • Comic Book Movies Don't Use Codenames: Unlike the other metahuman villains, Cisco never got to call him Weather Wizard.
  • Composite Character: Took his brother's role as the first Weather Wizard.
    • 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.
  • Foolish Sibling, Responsible Sibling/Red Oni, Blue Oni: Clyde is the Red Oni and Foolish Sibling to Mark's Blue and Responsible Sibling. Clyde is reckless while Mark is the more level-head
  • 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.
  • 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.
  • Pragmatic Adaptation: In the comics, the Weather Wizard's powers came from a technological "wand" he invented that enabled weather manipulation. In the show, he's a metahuman.
  • 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.
  • Stuffed In A Fridge: His death causes his big brother to go on a Roaring Rampage of Revenge.
  • 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.

     Danton Black/Multiplex 

Danton Black/Multiplex

Played By: Michael Christopher Smith

A scientist who was studying stem cell cloning who gains the power to duplicate himself.

     Kyle Nimbus/The Mist 

Kyle Nimbus/The Mist

Played By: Anthony Carrigan

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, gave him the power to change into a poisonous mist.
  • And I Must Scream/Fate Worse Than Death: He trapped - 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 to 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.)
  • Brick Joke: While Nimbus has yet to be seen since his debut, his poisonous gas form was briefly seen in The Stinger of Power Outage, and in Fallout Cisco mentions his continuing status to Ronnie.
  • Elemental Shapeshifter: Can transform into a poisonous gas.
  • 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 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.
  • 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.
  • Obviously Evil: If you saw this guy walking at you, would "Villain" not scream in your head?
  • 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.
  • Sealed Evil in a Can: At the end of his 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.
  • Super Smoke: Has the power to willingly turn into a cloud of poisonous gas and retain movement control.

     Bette Sans Souci/Plastique 

Sergeant Bette Sans Souci/Plastique

Played By: Kelly Frye

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 Bomb: An involuntary choice. After she was shot and killed by General Eiling, her own corpse turns explosive. Barry had to take her beyond the city limits so no-one else would be caught in the blast.
  • 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 Dr. Wells.
  • 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.
  • 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.
  • Good-Looking Privates: She's an Army Sergeant.
  • 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.
  • Mythology Gag: Once again she is prominently featured in one episode and killed off in her debut.
  • 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.
  • 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.

     Tony Woodward/Girder 

Tony Woodward

"Looks like you were born to take a beating."
Played By: Greg Finley

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.
  • 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.
  • 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, even no-selling (somewhat) his first attack. 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.
  • 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.
  • Death Equals Redemption: He gives Barry one last warning to run before succumbing to his wounds from Blackout's attack.
  • Elemental Shapeshifter: He can turn his body into steel.
  • 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.
  • 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.
  • Schoolyard Bully All Grown Up: From what we see in Barry's flashback, Tony was every bit as nasty as a kid.
  • 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.

     Farooq Jabron/Blackout 

Farooq Jabron/Blackout

Played By: Michael Reventar

An adventurous young man who went to see the particle accelerator with his friends. Was stuck in the middle of a storm 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/Glowing Eyes of Doom: 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 Wells takes a sample out of Farooq's corpse to try to figure out why.
  • Obviously Evil: Not to the extent of Kyle Nimbus, but Farooq has visible veins in his face, glowing eyes, and generally looks very creepy.
  • 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 Wells 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/Prism 

Roy G. Bivolo/Prism

Played By: Paul Anthony

A former artist turned metahuman bank robber, Roy has the power to induce a violent rage in people when he makes eye contact with them.
  • Adaptation Name Change: Prism instead of Chroma or Rainbow Raider, though Caitlin does suggest the latter name. In the comics, Prism is the alias of a different character.
  • Atrocious Alias: Turns out Bivolo actually prefers Rainbow Raider rather than Prism.
  • Hate Plague: His main power. Roy 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. This differs from his comic book counterpart, whose main power was Hard Light constructs.
  • Meaningful Name/Punny 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.
  • 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.

    Shawna Baez/Peek-A-Boo 

Shawna Baez/Peek-A-Boo

Played By: Britne Oldford

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.
  • 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.
  • 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.
  • 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.
  • Improbable Weapon User: She uses a pocket spyglass in order to increase the effectiveness of her teleportation, and also to beat people around with.
  • Kryptonite Factor: 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.
  • 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.
  • Undying Loyalty: Shawna still loves her boyfriend even after he leaves her at the last minute.

Leonard Snart/Captain Cold

"Thank you. You forced me to up my game; not only with this gun, but with how I think about the job. It's been educational."
Played By: Wentworth Miller

A world-class thief who gets a hold of a high powered, experimental cold gun.
  • Abusive Parents: His father was a bad cop who took his anger out on him and his sister.
  • Adaptational Attractiveness: He's perhaps the most handsome take on any versions of the character to date.
  • Adaptational Villainy: Captain Cold of the comics is a very strict anti-villain, who detests the idea of killing people unless he has to, especially innocents, would actively work to avoid civilian casualties, and was a Friendly Enemy with Barry. In the show, he's far more willing to endanger innocents (though, while he does mention not liking the idea of killing police officers, he specifies it's due to Pragmatic Villainy, not morals), even outright killing a man in cold blood (pun intended) to distract the Flash, and repeatedly kills other criminals he does deal with to avoid them spilling any information about him. He still seems to respect the Flash, but not to the same extent.
    • As the leader of the Rogues, in the comics he's more interested in petty theft (and even calls out those who harm women and children or at least try to); here, his main goal is to defeat the Flash.
    • He starts to gravitate more towards his comic book version in "Rogue Time", where he agrees to keep Barry's identity a secret — even if he does want to stay free in return and, when the Flash hurts his pride by saying he wouldn't need to kill anyone if he was as good at his job as he thinks he is, Cold takes up the challenge.
  • Affectionate Nickname: Cold is sometimes called "Lenny" by Lisa.
  • Alliterative Family: With his younger sister, Lisa.
  • Appropriated Appellation: The look on his face when Cisco calls him "Captain Cold" just screams this. He officially adopts the nickname as of Revenge of the Rogues.
  • Arch-Enemy: Second to the Reverse Flash. Wells actually goes on to call him Barry's "nemesis".
  • Awesomeness by Analysis: It's mentioned he studies potential targets for months before making his move, and describes police deployment and response time with extreme precision when the Flash foils the robbery in Going Rogue.
  • The Bad Guy Wins: The outcome of his first episode. He gets everything he wants, defeats the Flash, leaves him alive out of his own volition and walks away scot-free.
    • Kind of wins again when he returns in Revenge of the Rogues. While he wasn't able to get rid of the Flash, he accomplishes his other goal to at least expose the Flash to the public and still escapes prison at the end, as he prepared a Prison (Transport) Break in case he gets arrested. However, as of right now he and Mick lost their high-tech guns; still, this might be just a minor issue for him, since he and Mick are now familiar enough with the weapons' technology so they now might be able to make their own.
      • And again in "Rogue Time", he finds out Barry's secret identity and forces him into a Cooperation Gambit, escaping arrest once more, plus recovering his and Rory's weapons, and getting a new one for his sister.
  • Badass Normal: He's not a meta-human. He's just a criminal who got his hands on extremely powerful weapon that made him dangerous. And even without it he shows his most dangerous weapon is his brain.
    • He's also the first villain to score a clear victory over Barry.
  • Because I'm Good at It: Uses this as a justification on why he's a criminal.
  • Berserk Button: Someone working with him leaving a job (or "wanting out") before it's finished: he callously kills one of his men the moment he says he wants out and makes it clear enough to the other two what will happen if they try that they have to threaten to kill him so that he'll let them go. It's worth noting that none of his men had anything against him (and the ones who put a gun to his head didn't even seem to want to pull the trigger) and weren't actually betraying him, they just didn't think he was appreciating the risks The Flash created - yet Snart treated every case as bad enough to warrant murder.
  • Big Bad: Although they're still forming, Cold is the de facto leader of the Rogues.
  • Big Brother Instinct: He's protective of Lisa.
  • Blood Knight: In "Rogue Time" he states outright that his only motivation is the thrill of breaking the law, and knowing how good he is at it.
  • Book Dumb: As Caitlin is quick to point out, he never finished high school, but what he may lack in academic learning he makes up by genre savviness and careful observation.
  • Brother-Sister Team/Siblings in Crime: Is this with Lisa.
  • Card-Carrying Villain: The first of Barry's rogues to really embrace the villain nickname given to him by Cisco.
  • Civvie Spandex: He wears a longcoat and goggles, as opposed to the white and blue costume he wears in the comics.
  • Clock King: He carefully studies police response times down to the second.
  • Crazy-Prepared: Snart has a plan for everything. When he and Rory are being transported to Iron Heights, he's calm and collected. Why? Because in case that happened he already arranged to have his sister break them out as part of a contingency plan.
  • Dangerously Genre Savvy: He picks up on the fact that the Flash cares more about saving lives than stopping criminals, and he uses this to his advantage. He also had a backup plan if they lost, and had his sister on stand-by to break them out.
    • He also makes sure that Rory knows how to fix his Heat gun.
  • Determinator: In his introductory episode, Joe notes that while Snart has faced setbacks in the past, once he sets his sights on a prize, he never gives up until he gets it. In the same episode, we see what happens to members of his crew who don't share his persistence.
  • Didn't See That Coming: Didn't think that Flash would let himself get hit by both guns to force the streams to cross. But he was aware of the possibility of losing, and had a backup plan.
  • Even Evil Has Loved Ones: "You would do anything to protect your family, just like me."
  • Evil Is Hammy: In his first appearance, he was cold and professional at all times. By Revenge of the Rogues, he is clearly having a blast being a supervillain. There's a notable shift between his calm and cool attitude when not in costume, and his over the top mannerisms when in costume.
  • Evil Sounds Deep: He has a rather low, silky voice.
  • Faux Affably Evil: Acts very polite, if stern, most of the time, which just makes the more ruthless acts he commits even more unexpected.
  • Freeze Ray: His Weapon of Choice, which is said to be a miniature cold generator that shoots "flames" that achieve absolute zero.
  • From Nobody to Nightmare: From ordinary street thug to Central City's first true supervillain in a matter of days.
  • Gadgeteer Genius: While not as smart as Cisco - he's not able to create a new cold gun by himself - he is smart enough to disassemble, then reassemble it, and is familiar enough with its mechanics to know when Cisco tries to sabotage the second one Cold is forcing him to make.
  • Glass Cannon: He's not a metahuman, so he's just as vulnerable as a typical human being. However, his extremely high offensive powers thanks to his cold gun more than make up for this.
  • Goggles Do Something Unusual: Not really unusual; they protect his eyes from the glare that comes from the Cold Gun. Also counts as Stylish Protection Gear.
  • Graceful Loser: Takes his loss to Flash well. Probably because he had a backup plan
  • An Ice Person: Captain Cold isn't a metahuman like other villains so far, instead he uses a "cold gun" that can slow atoms down to absolute zero. Even before that, he used liquid nitrogen to freeze and break open an armored truck. He also offers a boy some cool mint gum.
  • An Ice Suit: Once he settles into his supervillain role, he dons a dark blue parka.
  • In the Hood: Wears a hooded dark blue parka as Captain Cold.
  • Jumped at the Call: Just check out the way his face lights up when he first hears his supervillain name. When he comes back in Revenge of the Rogues, it's obvious that he revels in the opportunity to be a bona fide supervillain.
  • Man of Kryptonite: His Freeze Ray was specifically built by Cisco to counter the Flash in case he ever went rogue. It was stolen by a janitor working at S.T.A.R labs who tried to sell it to Leonard who promptly used it on him. It turns Leonard from a skilled, yet petty thief to an dangerous threat. That said, Snart doesn't consider it to be the Flash's real weakness, but rather his need to help others.
  • Manipulative Bastard: Clearly enjoys manipulating events to benefit himself.
  • Movie Superheroes Wear Black: While he stills wears a blue parka, it's now a dark navy color rather than the bright shade seen in the comics.
  • My Sister Is Off-Limits!: Discussed, he's more shocked that his sister kissed Cisco as part of her Honey Trap, but he's not actually mad about it.
  • Nerves of Steel: Even though its only the fourth episode, by the time Snart's on the scene, people are aware of the Streak, and after his first robbery is foiled, his crew decides Central City is too hot for them. Snart, on the other hand, never shows fear, neither of Barry, the police, or even when his own crew draw down on him. He just makes a plan, and is able to hand the Flash a solid defeat.
  • Not So Stoic: He has the happiest smirk on his face when he hears Cisco dub him "Captain Cold". Also when Barry calls them the Rogues.
  • Personality Powers: Well, it's a gun rather than his own power, but he's still a stoic, calm professional that gets a cold gun. Justified since he specifically chooses the cold gun, even rejecting the heat gun he's offered before. Even before that, however, he used a liquid nitrogen projector in heists.
  • Pet the Dog: Offers a kid a stick of gum and banters with him while casing a museum.
  • The Plan: He begins forming one, once he gains his freeze ray and after his first battle with the Flash.
  • Pragmatic Villainy: Snart is willing to steal, kill, and endanger the lives of civilians to achieve his goals. However, he doesn't act without reason, and he chooses not to shoot cops or murder bystanders if he can help it, because it's not worth the time or the attention from the cops.
  • Pungeon Master: Passively pummels people with a plethora of ice puns.
  • Red Oni, Blue Oni: He's methodical and calculating and cool under pressure, compared to Heat Wave's hot-headed excitability.
    • Their costumes demonstrate the difference as well. Cold's outfit and goggles are quite a bit more stylish than Heatwave's, Cold's clean-shaven-crew-cut look is professional compared to Mick's 5-o'clock shadow, and even Cold's weapon is a front heavy sleek design compared to Heatwave's industrial bullpup flamethrower.
  • Shadow Archetype: Snart and Barry were both raised by cops, at one point saw their fathers going to prison, developed Awesomeness by Analysis and eventually got powers from STAR Labs — either permanently or through gadgets — but, in terms of personality, simply became powered-up versions of who they already were.
    Barry: Snart's dad is in prison, too? We should start a club.
  • Sinister Shades: They're goggles, but they're clearly meant to invoke this.
  • The Stoic: He almost never raises his voice and maintains a deadpan expression.
  • Thou Shalt Not Kill: Originally he has no problem with it if it gets the job done, but after he kidnaps Cisco, Barry challenges his pride by saying if he were as good as he claims he could do the whole supervillain thing without killing anyone, which Cold agrees to.
  • Unfortunate Names: "Leonard Snart" isn't going to be winning him any coolest names awards any time soon. Both Barry and Joe think it's lame.
  • Victory Is Boring: According to Miller, he's been pulling off flawless thefts with no consequences for so long it's grown boring, and he welcomes the challenge that the Flash presents.
  • Villainous Breakdown: May be in the early stages, as Mick claimed he was obsessed with the Flash to the point of forgoing his usual planning and pragmatism. Except not, it's all part of the plan.
  • Villainous Friendship: With Mick Rory.
  • Villain Team-Up: Despite encountering and battling the Flash a couple of times, Snart's Genre Savvy enough to go and recruit allies in battling against the Flash.
  • Virtue Is Weakness: He consider's the Flash's real weakness not to be his Freeze Ray, but the fact that he helps people. He takes advantage of this by derailing a train and forcing him to save all the passengers.
  • White Hair, Black Heart: His hair has a distinct silver shade.
  • With Friends Like These...: With Mick Rory. They seem to be friends but they're perfectly willing to point guns at each other if one of them screws up a job.
  • Worthy Opponent: Seems to see the Flash as this, going as far as thanking him for keeping him on his toes.

     Mick Rory/Heat Wave 

Mick Rory/Heat Wave

"The fire revealed my true self, showed me who I really am. I wonder what the Flash will reveal when I burn his suit and skin off."
Played By: Dominic Purcell

An old friend of Leonard Snart's, whom he recruits after running into the Flash.
  • Adaptational Villainy: Rory dabbled in the Heel-Face Revolving Door, and his mental issues are portrayed sympathetically.
  • Ax-Crazy: He's way too fond of playing with fire for even his own good and threatens to use it on Caitlin when she's in his and Snart's captivity.
  • Badass Bookworm: Though he had to be told to learn it by Snart, Mick has taken to learning exactly how his gun works so that he can repair it if necessary.
  • Bald of Evil: Similar to Snart's crew cut, but he has stubble as well, making him look rougher.
  • Casting Gag: Dominic Purcell and Wentworth Miller are teamed up. Again.
  • Composite Character: He's heavily burned like his Prime Earth Metahuman incarnation, but still uses a flamethrower ala pre-Flashpoint.
  • Evil Sounds Deep/Guttural Growler: As part of the contrast to Snart, Mick has a very rough, gravelly deep voice in comparison to Snart's smoother baritone.
  • Evil Is Hammy/Large Ham: Purcell is clearly having a ball with the role, and it makes him stand out compared to Miller's stoic performance.
  • Fire-Breathing Weapon: Snart gives him a high-tech flamethrower stolen from S.T.A.R. Labs. It superheats the air (hence Cisco calling him "Heat Wave"), and can do the inverse of Snart's Freeze Ray, instead heating up objects to Planck temperature, or as Cisco calls it, "absolute hot".
  • First Name Basis: Snart calls him Mick.
  • From Nobody to Nightmare: From a burnt criminal to a super-villain.
  • Gadgeteer Genius: He's smart enough to repair his flamethrower after it gets damaged in a shootout.
  • Glass Cannon: He's not a metahuman, so he's just as vulnerable as a typical human being. However, his extremely high offensive powers thanks to his heat gun more than make up for this.
  • Goggles Do Something Unusual: Less unusual than Snart's, as they are meant to protect him from the glare of actual fire, rather than an absolute zero gun.
  • Good Scars, Evil Scars: He has severe burn scars all over his arms, and possibly the rest of his body.
  • Handicapped Badass: Subverted. He suffered third-degree burns that left him with disfiguring scars, but there's been no indication as yet that the damage is anything more than cosmetic.
  • Hot-Blooded: This should be obvious.
  • Know When to Fold 'Em: He wants to quit after he and Snart get the painting, but he is convinced otherwise.
  • Laughing Mad: At one point, he's shooting flames all over the place and cackling like a witch.
  • Locked Out of the Loop: Snart kept his sister a secret so she could break them out of jail. He stops being upset with Snart after that.
  • Mood-Swinger: Swings pretty violently between somewhat jovial and mean as all hell.
  • Odd Friendship: With Snart. Mick's hot blooded nature and pyromania is often a Spanner in the Works for Snart's carefully planned heists. Snart in turn, often keeps him Locked Out of the Loop and there's not a lot of respect on both sides. It's surprising that they work together and haven't killed each other for one reason or another. The one thing that they seem to share in common is that (after just a little convincing from Snart) they both seem to agree that being supervillains is in itself worth more than the money they can make from pulling heists.
  • Playing with Fire: His flamethrower.
  • Pyromaniac: Snart implies Rory enjoyed "playing with fire" even before being given his new weapon. "Revenge of the Rogues" confirms this.
  • Red Oni, Blue Oni: He's hot-headed and excitable compared to Cold's methodical, calculating, and cool-under-pressure personality.
    • Their costumes demonstrate the difference as well. Cold's outfit and goggles are quite a bit more stylish than Heatwave's, Cold's clean-shaven-crew-cut look is professional compared to Mick's 5-o'clock shadow, and even Cold's weapon is a front heavy sleek design compared to Heatwave's industrial bullpup flamethrower.
  • Refusal of the Call: He's reluctant to stick with the supervillain shtick until Cold convinces him that it's their true calling.
  • Two First Names: Being a DC Comics based character, he has a last name that is traditionally used as a first name.
  • Villainous Friendship/Villain Team-Up: With Captain Cold.
  • With Friends Like These...: With Leonard Snart. They seem to be friends but they're perfectly willing to point guns at each other if one of them screws up a job.

     Lisa Snart 

Lisa Snart

Played By: Peyton List

The younger sister of Leonard Snart, who busts her brother and Heat Wave out of a prison transport.
  • Abusive Parents: Same deal as her brother.
  • Adaptation Dye-Job: In the comics she is blonde, which together with her yellow/orange costume and ice-skater theme led to her alias Golden Glider (later shortened to Glider). Here she is a brunette, but briefly wears a blonde wig.
  • Alliterative Family: With her big brother, Leonard.
  • Aloof Dark-Haired Girl: Once she no longer needed her facade, she never stopped snarking at people.
  • Brother-Sister Team/Siblings in Crime: Is this with Captain Cold.
  • Dark Action Girl: By the sounds of it, she was able to handle all the security surrounding the prison transport without breaking a sweat — and with a lot of bullets. This is confirmed in "Rogue Time", where she shows herself to be about as good at fighting and using guns and gadgets as her brother.
  • Drives Like Crazy: She's not the best at driving.
  • The Faceless: In her debut appearance.
  • Gold Makes Everything Shiny: Gets Cisco to build her a gun that encases her targets in a gold-like substance.
  • Hell-Bent for Leather: Wears a heavily leather-y outfit in her official appearance.
  • Honey Trap: Does this to Cisco to get Cold and Heatwave's guns back.
  • Mythology Gag:
    • Lisa's first appearance, involving her easily busting Captain Cold and Heat Wave out of a prison transport, is just like her New 52 debut as The Glider.
    • Unlike most other villains in the show, her gimmick is significantly different (she doesn't "glide", either through skating or astral projection) so her gold gun is more of a nod to the "Golden" part of her alias.
  • Sibling Team: With Captain Cold.
  • The Stinger: She first appears at the very end of Episode Ten, though mostly off-screen.
  • Woman in Black: She's clad in black from head to toe in her official appearance.

Other Non-Metahuman Criminals

    Hartley Rathaway/Pied Piper 

Hartley Rathaway/Pied Piper

Played By: Andy Mientus

The disowned son of a wealthy industrial family, former scientist at STAR labs and protégé of Dr. Wells until he was fired and lost his hearing due to the particle accelerator explosion.
  • Alliterative Name: Starts calling himself the Pied Piper.
  • Arch-Enemy: He is Cisco's Rival Turned Evil.
  • Badass Gay: He's gay and a genius able to almost kill Barry.
  • Badass Normal: Not a metahuman, just a super smart dude with killer sonic technology who was almost able to kill Barry.
  • Batman Gambit: A favorite of his. Out-gambits pretty much the entire Team Flash in his debut episode. And in the following one, he plays Cisco and manages to escape.
  • Black Cloak: Part of his supervillain outfit.
  • Brains and Bondage: The brains are well-documented. The bondage is Downplayed, as the show is on CW rather than HBO - twice now, Hartley has directly mentioned kink (his fantasy about a man in head-to-toe leather to Barry and mentioning rough trade when Cisco handcuffs him) in what primarily seems to be an attempt to make them uncomfortable, but his casual language also has BDSM allusions (referring to Wells as Cisco's "master" and Barry as Wells's "pet").
  • Chekhov's Gunman: He's mentioned in "Revenge of the Rogues" but first appears in "The Sound and the Fury."
  • The Chessmaster: Makes a lot of chess references and used to play with Wells. More importantly, in his debut episode he's several steps ahead, engineering his capture in order to gain information on how to kill Barry, and nearly succeeding in doing so.
  • Cunning Linguist: In addition to his native English, he speaks fluent Spanish, French and Latin.
  • Deal with the Devil: Offers one to Cisco at the end of "The Sound and The Fury": if freed, he will reveal where Ronnie is and help turn him back to normal. He succeeds.
  • Decomposite Character: In the comics Hartley, not Cisco, is the Flash's tech-savvy best friend, and a Canon Foreigner supplants him as the lover of Barry's superior officer.
  • Emerald Power: The lights on his stunners glow green.
  • Expy: With the change of his weapon to gloves, he actually bears quite a resemblance to Shriek from Batman Beyond; especially because, just like Shriek, Rathaway gets severe auditory problems because of an accident, unlike the comics where he's deaf since birth.
  • Face-Heel Turn: In his backstory. Sure, he was a jerk, but he still tried to warn Wells that the Particle Accelerator had a severe chance of blowing up. Of course, Wells already knew and fired him. Then he lost his hearing after the explosion and went off the deep end.
  • The Friend Nobody Likes: Was once this to everyone at STAR Labs because, as Cisco puts it, "mostly, he was a jerk. But sometimes... he could be a dick".
  • Good Is Not Nice: He was a major dick back in the day, but he was determined to stop the accelerator because he had figured out it could blow and he was entirely unwilling to let that happen. Wells fired him and coerced him into staying silent. Still. Major dick.
  • Handicapped Badass: Suffered major damage to his ears and requires special hearing aid, but is still a genius and a competent fighter.
  • He Knows Too Much: Wells fired Hartley because he found out about "a chance" that the accelerator would explode, and threatened to ruin his credibility if he exposed this fact for good measure.
  • Ignored Expert: Knowledge on the particle accelerator's failure that led to his getting sacked by Wells.
  • I Have No Son: His estranged father's reaction when Hartley tries to contact him. Turns out he was disowned for being gay (as Caitlin puts it "old money, old values"). Something he was not happy about.
  • In the Hood: As part of his supervillain outfit.
  • Insufferable Genius: He makes Wells look humble in comparison.
  • I Surrender, Suckers: Twice. The first time he gets captured on purpose in order to steal all STAR Labs' data regarding Barry. The second time, he allows Barry to disarm him, so that the failsafe in his gauntlets would activate and melt Barry's brain. (He even calls Barry out on falling for it twice)
  • It's All About Me: His main reason for fighting the Flash is because he replaced him as Wells' favorite. The fact Wells had him fired for threatening the Particle Accelerator project was in the end less about being concerned for the city's welfare and more about being betrayed by his father figure.
  • Jerkass: Comes with the above. Everyone hates him, and for a good reason.
  • Jerk with a Heart of Gold: As much of a Jerkass as Hatley may be, he still cared enough to try and fix the Particle Accelerator and was unwilling to risk the lives of everyone in the building and possibly the city and was perfectly willing to admit to the public that there was a mistake. Unfortunately, he got worse after the accident...
  • Jerk with a Heart of Jerk: Comes off at this at his worst, ESPECIALLY during his debut episode. As Cisco explains, "Mostly, he was a jerk, but sometimes... he could be a dick."
  • Kick the Dog: After being captured by Barry, he tells Caitlin he didn't get his wedding invite. Also tends to attack people when they can't fight back such as sucker punching Caitlin or kicking Cisco when he is disabled by a sonic device, even though not doing so would be more pragmatic.
  • Lack of Empathy: Cited as a major reason for his fall from grace. He and Cisco are intellectual equals, but he doesn't give two shits about anyone. Subverted when he told Wells about the particle accelerator and the possibility of it blowing a hole in Central City.
  • Leatherman: He tells Barry that being captured by a guy wearing leather is a long time fantasy of his.
  • Manipulative Bastard: He's pretty good at this, as proven by how he convinced Cisco to let him out of his cell. Honestly, if he weren't such a Smug Snake, he'd probably qualify as a Magnificent Bastard.
  • Movie Superheroes Wear Black: His attire is fully black. In the comics, at least the cloak is usually green.
  • Nerd Glasses: Wears a pair. Not that it makes him any less of a Badass.
  • No Social Skills: Wells states that, in exchange for being brilliant, he has no skills with people.
  • Obnoxious Snarker: As already stated, Hartley's an ass and constantly states his opinion on everyone else with sharp one-liners.
  • Pragmatic Adaptation: Playing a pipe like in the comics would have been nifty, but it's not a practical thing to convey so the change in his manner of weaponry does make sense in that regard.
  • Punny Name: Rathaway sounds so suspicious for a guy whose Code Name is the Pied Piper.
  • A Pupil of Mine Until He Turned to Evil: A former colleague of Wells until Wells fired and threatened him to keep him from telling the press about the Particle Accelerator.
  • Revenge: His goal against Wells.
  • Rival Turned Evil: For Cisco. They already have a rocky relationship, but his Face-Heel Turn cemented him being his Arch-Enemy.
  • Slobs Vs Snobs: His conflict with Cisco. Hartley couldn't believe someone like Cisco could be a mechanical genius.
  • Smart People Know Latin: He and Wells would often converse in Latin.
  • Smug Snake: For all of his cunning plans, he's so arrogant and obnoxious and petty that he just doesn't manage to be a Magnificent Bastard, especially not compared to Harrison Wells.
  • Sonic Stunner: His weapon of choice.
  • Spanner in the Works: Surprisingly, gets incredibly close to being one to Wells. He tries to fix the Particle Accelerator. Had he succeeded, Wells' plan to create the Flash would've failed.
  • Straight Gay: Aside from a brief moment where he taunts Barry, he comes off as this.
  • Too Soon: Deliberately invoked to hurt Caitlin.
    Hartley: Caitlin. Didn't get that wedding invite.
  • Took a Level in Jerkass: Goes from obnoxious (yet considerate enough to try to fix the Accelerator) genius to sociopathic terrorist and would-be murderer.
  • Troll: When being captured by the Flash, he takes the opportunity to troll the Flash about his costume and Caitlin about losing her fiance to the accident.
  • Villain Has a Point: His motive is to get revenge on Wells due to being betrayed by him, but Wells makes everyone think that it was due to his obstinate personality. In truth, Hartley was callously fired by his father figure for even knowing about the chance that the accelerator would explode, also threatening him to ruin his credibility so that he would never get any other job.
  • Villains Never Lie: He did keep his end of the bargain with Cisco, before kicking him to the ground.
  • "Well Done, Son!" Guy: Since he was disowned from his parents, Wells became a father figure to him.
  • Would Hit a Girl: Slaps Caitlin so hard he knocks her out.

     Clay Parker 

Clay Parker

Played By: Micah Parker

The boyfriend of Shawna Baez, who breaks him out of prison.
  • Beard of Evil: He is sporting a goatee.
  • Dirty Coward: Abandons Shawna to the Flash after he finds a way to shut off her powers.
  • Outlaw Couple: With Shawna, until he abandons her.
  • Ungrateful Bastard: Leaves Shawna when Barry is about to catch them despite her doing everything to free him from prison.

Starling City Citizens

     Oliver Queen/The Arrow 

Oliver Jonas Queen/The Arrow

Played By: Stephen Amell

The main and eponymous character of Arrow, a vigilante in Starling City. See Arrow Main Characters.
  • Awesomeness by Analysis: His appearance in "Flash vs Arrow" involves him attributing his being still alive to this and trying to teach Barry how much being in their line of work requires it. He points out that Barry has the potential to be even better at it than he is, because his superspeed gives him all the time in the world to case out and analyze any given situation.
  • Badass Normal: No powers. Just training. Still 100% badass.
  • The Cameo: He appears in the pilot to further encourage Barry to become a superhero.
    Barry: I'm just not sure I'm like you, Oliver. I don't know if I can be some vigilante.
    Oliver: You can be better, because you can inspire people in a way that I never could. Watching over your city like a guardian angel, making a difference, saving a flash.
  • Cannot Convey Sarcasm: The reason why Felicity didn't know he was literally going to shoot Barry with an arrow is that she couldn't tell if he was joking or not.
  • Did Not Get the Girl: Tries to invoke this word-per-word to Barry to help him stop him from torturing himself from his unrequited love.
  • Experienced Protagonist: This is highlighted numerous times during the crossovers. When Barry was struck by Bivolo's Hate Plague and was required to be stopped by Oliver, their respective team members except Felicity (who is close to both and thus more concerned about the situation happening than the possible outcome) had an argument with Diggle invoking this very trope in the discussion.
    Caitlin: I just hope they (Wells and Joe) can turn Barry back before he kills Oliver.
    Diggle: Me, I'll be more worried with what Oliver might have to do to Barry.
    Caitlin: Barry has super powers. Oliver has a bow and arrow.
    Diggle: Do you have any idea how many people Oliver killed with that bow and arrow?
    Cisco: Recurve bow arrows can travel up to 300 feet-per-second, so, like, 200mph? Barry can run three times that fast.
    Diggle: Whatever. Oliver's been doing this a lot longer; my money's on experience.
    Cisco: My money's on speed.
    Felicity: Please tell me you're not actually having this conversation right now?!
  • Hero of Another Story: Obviously.
  • Let's You and Him Fight: In "Flash vs Arrow", Barry has been hit with the Hate Plague and they get into a fight. It ends in a draw.
  • Long-Lost Relative: A variant. During his visit, he meets the woman he impregnated whom his late mother "exiled". After he leaves, the woman talks to her and Oliver's implied child over the phone.
  • Mr. Fanservice: Iris, in particular, notices, and says that his arms are twice the size of Barry's.
  • Secret Keeper: Mutually with Barry/The Flash.
  • Sensitive Guy and Manly Man: Everytime he and Barry are together, his "tough-as-nails" demeanor/personality is often highlighted.
  • Sink-or-Swim Mentor: Much to Barry's initial resentment. Comes with it being how he was taught, too.
  • “Stop Having Fun” Guy: Scolds Barry for nicknaming his criminals, not casing the scene before rushing in and in general, treating crime fighting as a game.

     Felicity Smoak 

Felicity Megan Smoak

Played By: Emily Bett Rickards

Oliver Queen's right-hand woman. See Arrow Main Characters.

     John Diggle 

John Diggle

Played By: David Ramsey

Oliver Queen's right-hand man. See Arrow Main Characters.
  • Aloof Ally: He doesn't interact with Team Flash as much as Felicity and Oliver does.
  • Heroic BSOD: A comedic one happens to him when he sees Barry's powers for the first time. Needless to say...
    Diggle: I had a cousin who got struck by lighting once. He just developed a stutter.
  • Unusually Uninteresting Sight: Inverted. Unlike Ollie and Felicity, it took him a while to adjust to Barry having super powers. Ollie says that powers or not, this is still the same Barry they befriended back in "The Scientist"/"Three Ghosts".

     William Tockman/Clock King 

William Tockman/Clock King

Played By: Robert Knepper

One of the Arrow's old foes who gets transferred to Central City Prison. See Arrow Villains for his other tropes.
  • Evil Vegetarian: Demands a vegetarian take-out meal from the police.
  • Four Eyes, Zero Soul: Wears a very distinctive pair of glasses.
  • Happy Ending Override: He wasn't able to save his sister, as we were left with the possibility of on Arrow.
  • Incurable Cough of Death: More like a wheeze and general trouble breathing, but it's very noticeable that his disease is taking its toll.
  • Motive Decay: On Arrow he wanted to get enough money to save his sister. After he failed and wasn't even allowed to say goodbye, now he only cares about getting out of jail for his little remaining time before his own death.
  • Pet the Dog: He shot Eddie, but gives Iris a chance to say goodbye...since he didn't get to say goodbye to his sister.
  • Worf Had the Flu: He wouldn't have lasted a second against the Flash, except that Barry happened to have lost his powers at the time.

     The Royal Flush Gang 

The Royal Flush Gang

A family of bank robbers originating in Starling City, they make the move to Central City and are soon after captured by the Flash after pulling a heist. See Arrow Villains for their other tropes.
  • Cool Bike: The three use BMX bikes to make their escape, and they almost would have made it were they not facing a hero with Super Speed.
  • Legacy Character: The previous King of Spades, Derek, was killed during a heist in Starling City. Since the Gang appear with a King but without an Ace, it's clear that the previous Ace (Kyle) took on the position.
  • Rogues-Gallery Transplant: They were already moved from the Justice League to the Arrow, and now again onto the Flash.
  • Wrong Genre Savvy: They may have been able to fool the Arrow if they had tried their tactics on him, but they clearly weren't prepared for a speedster who could chase them all even when they split up.
    • What an Idiot: That being said, they did try to rob banks in a city that had officially confirmed the presence of an impossibly fast superhero stopping criminals only a week prior to their heist.


     Nora Allen 

Nora Allen

Played By: Michelle Harrison

Barry Allen's mother and Henry Allen's wife.



Voiced By: Morena Baccarin

An AI that assists Harrison Wells.
  • Artificial Intelligence: One that works for Wells.
  • Casting Gag: Morena Baccarin is a DC Comics "go-to actress" for many of its adaptations.
  • Gender-Blender Name: Though it technically has no gender since it's an AI, it has a traditionally male name but a female voice.
  • Secret Keeper: The only other character who knows that Harrison is from the future and is the Reverse-Flash.
  • The Voice: The only thing that we know from it/her.

     Simon Stagg 

Simon Stagg

Played By: William Sadler

A possibly corrupt businessman set to receive a reward for his research in organ cloning.

     Wade Eiling 

General Wade Eiling

Played By: Clancy Brown

A US Army General who's collaborated with Harrison Wells in the past. He returns to Central City after Bette San Souci reveals herself.
  • Arc Villain: for the Firestorm storyline. While he doesn't appear until near the end, his confiscation of Stein's research is an indirect catalyst for Stein going to STAR Labs and getting into the accident with Ronnie.
  • Asshole Victim: He was such a smug, power-hungry dick that it's hard to feel sad when Wells sics Grodd on him.
  • Badass Baritone/Evil Sounds Deep: As only Clancy Brown can pull off.
  • Big Bad Wannabe: Played With. He is a genuine threat and someone to be concerned about, but is relatively minor in the grand scheme of things compared to Wells, the Reverse-Flash. After having enough of Eiling's crusade to turn the meta-humans into living weapons he has him dragged off by Grodd at the end of "Fallout".
  • Casting Gag: One of Brown's best known roles is Lex Luthor in the DCAU (where Eiling was voiced by the similar-sounding J. K. Simmons).
  • Crazy-Prepared: He's quick to get to work making weapons for specific use against each metahuman.
  • Dangerously Genre Savvy:
    • He's the first to figure out that the Particle Accelerator Explosion gave the meta-humans their powers, and he threatens Wells with that knowledge in order to try to blackmail him to use the meta-humans as living weapons. Wells has none of it, and points out he knows things about Eiling's past that could easily get him disgraced.
    • In his second appearance when find out that he had weapons made to counteract the Flash.
  • The Determinator: Wells notes that once he has a target in sight, he doesn't let up.
  • Evil Old Folks: He wants to use meta-humans as living weapons, throwing the ethics and morality of such things to the wind.
  • General Ripper: It is Wade Eiling we're talking about.
  • Jack Bauer Interrogation Technique: Uses this to try to get information on Project Firestorm from Professor Stein.
  • Jerkass: He's rude to everyone, though a little less to Wells, mostly due to being wary of him.
  • Laser-Guided Karma: He use to torture Grodd with a cattle prodd back when he was at STAR Labs. Grodd remembers all too well. When Wells reunites the two, Grodd is very eager for vengeance.
  • Mysterious Past: It has yet to be fully expanded on, but Wells claims that Eiling has a history of doing less than ethical things that involve science experiments for the purpose of human super soldiers.
  • Screw the Rules, I Make Them!: He's a powerful army general who's willing to bend and outright break rules and laws to get what he wants.
  • Unwitting Pawn: It is implied Wells gave him Martin Stein to force Ronnie and Stein to re-merge, for an as-of-yet unknown reason. Wells kills Eiling once this is done.
  • Visionary Villain: How he justifies using meta-humans as super soldiers.
  • You Have Out Lived Your Usefulness: Pulls this on Bette San Souci and tries to on Firestorm - twice. Thus it's pretty karmic that Wells disposes of him once he is no longer useful to his plans.



Played By: Simon Burnett
Voiced By: Frank Welker

A gorilla who lived in Star Labs under Wells' care prior to the accelerator malfunction. General Eiling wanted to use him in mind control experiments, but Wells was adamant that any such test were to cease as long as Grodd was under his care. He disappeared following the night of the accident. Later some maintenance workers go down to a sewer tunnel in a section of the city where the power keeps going off, and are in for nasty surprise.

    Tina McGee 

Dr. Christina "Tina" McGee

Played By: Amanda Pays

The head scientist of Mercury Labs, a rival to S.T.A.R. Labs which developed tachyon technology that the Reverse-Flash tries to steal.
  • Adaptational Villainy: While she isn't truly a villain, she is portrayed in a much darker light than her original counterpart and the previous adaptation. This version of Dr. McGee is described as an "egomaniac" and behaves as antagonistically as possible towards Barry and S.T.A.R. Labs.
  • Age Lift: As a result of the same actress who portrayed her in the 90s series reprising her role, this incarnation of Tina is notably older than prior versions, as well as Barry.
  • Remake Cameo/Role Reprisal: Pays first played Dr. Tina McGee in the 1990s Flash show, where she was the confidant and teased love interest of Barry Allen.
  • The Rival: To Wells and S.T.A.R. Labs. The two don't have a high opinion of each other.

     Jason Rusch 

Jason Rusch

Played By: Luc Roderique

A grad student who worked with Professor Stein on the F.I.R.E.S.T.O.R.M. project, and informed Caitlin of his disappearance.
  • Age Lift: He's normally depicted as college aged. Here, he's a grad student, thus making him at least around in his mid-twenties.
  • Properly Paranoid: He explains to Caitlin that after the military seized everything from the project and Stein disappeared, he's been looking over his shoulder ever since.
    Jason: Am I being too paranoid? Or not paranoid enough?
  • The Rival: To S.T.A.R. Labs, somewhat. He applied for a job there before the reactor explosion, but afterwards ended up working with Tina McGee at Mercury Labs instead.
