The Flash is an American television series developed by Greg Berlanti, Andrew Kreisberg, and Geoff Johns, based on the DC Comics character the Flash. The series premiered on The CW television network in the United States on October 7, 2014, and has concluded its seventh season. The series is a spin-off from Arrow, and set in the same fictional universe.
The first season follows police forensic investigator Barry Allen (Grant Gustin), who develops super-speed after he is struck by lightning. He is assisted by S.T.A.R. Labs' Dr. Caitlin Snow (Danielle Panabaker), Cisco Ramon (Carlos Valdes), and Dr. Harrison Wells (Tom Cavanagh) in his attempts to use his powers for good and solve the murder of his mother by a superhuman attacker. The murder investigation unjustly imprisoned his father (John Wesley Shipp), leaving detective Joe West (Jesse L. Martin), father of his best friend, Iris (Candice Patton), to take in the young Barry. The memory of his mother's murder and his father's framing later motivates Barry to put his personal needs aside and use his powers to fight against those who hurt the innocent, thus, shaping him into the very well known and loved Flash.
The second season sees Barry and his allies dealing with the ramifications of their battle with the Reverse-Flash when a villainous speedster called Zoom (Tony Todd) arrives from the parallel universe, Earth-2, to kill all speedsters in the multiverse. To stop him, they will have to join forces with the Flash of Earth-2, Jay Garrick (Teddy Sears). In the third season, Barry creates another timeline dubbed "Flashpoint" after going back in time to save his mother. When he undoes it, he inadvertently changes the timeline and gives rise to the villain Savitar (Tobin Bell), who seeks to kill him and everyone he loves. With help from Joe's estranged son, Wally West (Keiynan Lonsdale), who becomes the heroic speedster Kid Flash, Barry must find a way to defeat a god-like being.
In the fourth season, after Barry disappears into the Speed Force to stop Savitar, super-genius Clifford DeVoe (Neil Sandilands) lures him back out; creating 12 metahumans as part of a mysterious plot in the process. Though Wally departs to find his own way, Team Flash gain new allies in private detective turned superhero Ralph Dibny / Elongated Man (Hartley Sawyer), district attorney Cecile Horton (Danielle Nicolet), and a mysterious girl who later introduces herself as Barry and Iris' daughter, Nora West-Allen (Jessica Parker Kennedy). In the fifth season, due to Nora coming back in time to help Barry defeat DeVoe, the serial killer Cicada (Chris Klein) was brought into existence years before he was supposed to. Now she must operate alongside her father and his allies as the superhero XS to undo her mistake while also combatting individuals armed with meta-tech created by DeVoe's defeat.
In the sixth season, just after Team Flash loses Nora, they learn from a multiversal being called the Monitor (LaMonica Garrett) that Barry must die in an impending Crisis so billions can live. While making preparations for this, they must also deal with threats from bloodthirsty doctor Ramsey Rosso (Sendhil Ramamurthy), the criminal organization Black Hole, and quantum engineer Eva McCulloch (Efrat Dor). To help them, the team gain allies in scientist Chester P. Runk (Brandon McKnight) and former metahuman criminal Allegra Garcia (Kayla Compton). In the seventh season, following the team defeating Eva, Team Flash deals with new threats from when they recreated the Speed Force, the Strength Force, the Sage Force, and the Still Force. Afterwards Team Flash must deal with a war caused by the speedster Godspeed.

After the particle accelerator explosion on Earth-2, she develops the powers of cryokinesis as Killer Frost. Her powers turned her hair white and her lips and eyes blue; she is unable to touch anyone without exposing them to absolute sub-zero temperatures and killing them. The only person immune to this is Deathstorm. Initially betraying Zoom's Earth-1 enemies, Caitlin helps them escape from Earth-2. After Zoom murders Deathstorm, Caitlin tries to murder her doppelgänger out of revenge; Zoom kills her for this.

Cosnett was originally slated to portray Jay Garrick in the pilot before the character was changed to Eddie Thawne.[4] Fans thought that he was playing the Reverse-Flash in disguise, due to his last name and appearance.[5]
Cisco Ramon / Vibe / Mecha-Vibe
Francisco Baracus "Cisco" Ramon (portrayed by Carlos Valdes; seasons 1–7) is a mechanical engineering genius who works at S.T.A.R. Labs, also known by the superhero codename Vibe. He is based on the DC Comics character of the same name.
- Valdes also portrays his character's Earth-2 doppelgänger, the metahuman villain Reverb, an enforcer for Zoom and wrangler of Killer Frost and Deathstorm. Reverb has more experience and control of his powers than his Earth-1 self; he has been aware of Vibe's existence and powers even before Vibe appears on Earth-2. He can manipulate sonic vibrations to create powerful shock waves of considerable strength, and it is implied that Reverb's power level surpasses both Killer Frost and Deathstorm, because they are intimidated by him. He is killed by Zoom.[3] Reverb's visor technology is obtained by his Earth-1 counterpart following his death, and Harry later uses its components to modify Vibe's own visor.
- Valdes also portrays his character's Earth-19 doppelgänger Echo, a hacker who is responsible for murdering Gypsy. Breacher and his fellow Collectors thought that Cisco was responsible as he and Echo share the same face, but Cisco's able to distract Echo long enough for the Collectors to find out who the real culprit is and trap his villainous doppelgänger so they can arrest him and send him to prison on Earth-19.

 | This section needs to be updated. (November 2021) |
Joseph "Joe" West (portrayed by Jesse L. Martin; main: seasons 1–8;[7] recurring: season 9) is a CCPD detective, father of Iris, Wally and Jenna West, and legal guardian to Barry Allen following Nora Allen's death and Henry Allen's incarceration.[8]
- Martin also portrays the Earth-2 Joseph West, a lounge singer who does not share a father-son bond with Barry and actually blames him for Iris becoming a police officer. Earth-2 Joseph is killed by Deathstorm.[3][9]
Wally West / Kid Flash
Wallace "Wally" West (portrayed by Keiynan Lonsdale; main: seasons 2–4; guest: seasons 5–6) is Iris' previously unknown brother and Joe's son,[10][11] described as "a bit of a wayward kid who has some attitude problems and some authority issues and is quick with a sassy remark".[12] Based on the DC Comics character of the same name, the character later inspired another character of the same name following DC's New 52 relaunch.[citation needed]
Lonsdale decides that he will not be returning full-time on season five, due to wanting to seek other acting opportunities.[13] It was always intended for Wally to be the son of Joe and brother of Iris, which differs from the character's comic history, as the producers felt it "weird" for second seasons of television series to introduce previously unmentioned cousins of established characters.[11] Keiynan Lonsdale originally auditioned for Legends of Tomorrow to portray Jefferson "Jax" Jackson.[14]
Clifford DeVoe / Thinker
Clifford DeVoe (portrayed by Neil Sandilands; season 4) is a metahuman with superhuman intelligence, who seeks to fix all that he deems wrong with humanity as the Thinker and the main antagonist of season four.[15][16][17] with Kendrick Sampson,[18] Sugar Lyn Beard,[19] Miranda MacDougall, Arturo Del Puerto, and Hartley Sawyer also portraying the character in different host bodies. His character was foreshadowed by Abra Kadabra and Savitar in the third season as a future nemesis of Team Flash's equal to Eobard Thawne / Reverse-Flash and Hunter Zolomon / Zoom in enmity. This version of DeVoe was originally a mild-mannered professor who believed humanity's emotions and technology had corrupted it and sought to change the way others think. This leads to him and his wife Marlize DeVoe to develop the "Thinking Cap" and exploit Thawne's particle accelerator to power it in order to increase his intelligence. While it was a success and he became the smartest man alive, DeVoe learned that the dark matter he absorbed into his mind was draining energy from his body, afflicting it with an advanced form of amyotrophic lateral sclerosis. Using his intelligence and Marlize's engineering skills, they build a hover-chair and cybernetically enhance him to delay his affliction, which leads to him developing a god complex and becoming apathetic and emotionless. Following this, DeVoe orchestrates Barry Allen's release from the Speed Force to create 12 specific metahumans for his plan to regress humanity's intelligence as part of his "Enlightenment" to the world. For the first phase, he captures the metahuman Weeper to keep Marlize under his control, orchestrates Barry's suspension from the Central City Police Department, and reveals his knowledge of Barry's secret identity to him, after which DeVoe takes the name "The Thinker". Following Barry's wedding,[p] DeVoe enlists Amunet Black to frame Barry for his "death" and transfer his mind into the bodies of metahumans Brainstorm, Hazard, Fiddler, and Folded Man to acquire their powers, as well as those of Kilg%re, Dwarfstar, Black Bison, Melting Point, and Null. Along the way, DeVoe also manipulates Harry Wells into creating his own "thinking cap" in order to test the Enlightenment's effects on a smaller scale, with Wells' cap temporarily augmenting his intellect before eventually reducing him to below-average intelligence. By the time DeVoe takes Elongated Man's body to stabilize the consolidated dark matter from his transferences, Team Flash discovers DeVoe arranged the 12 metahumans' creations to possess a healthy body and numerous powers to counter them and their allies. Even in spite of Marlize discovering what he had done to her and leaving him, DeVoe moves forward with his endgame by hijacking five satellites, including that of S.T.A.R. Labs', and using the last metahuman, Fallout, as a sacrificial power source. After Team Flash and Marlize use Cecile Horton's prenatal telepathic powers to project Barry into the Thinker's mind, they discover he metaphysically killed his former self and intended to take the Flash's body so he could become omniscient. However, Barry finds Elongated Man's consciousness and gives him back control of his body, forcing DeVoe to transfer his consciousness into his chair and become a virtual construct to survive. Though Marlize rips out his chair's power core to defeat him, she inadvertently triggers a fail-safe which shuts down S.T.A.R. Labs' satellite and sends it on a collision course with Central City. Barry and XS successfully destroy it, but in season five, Team Flash discover the debris created new metahumans such as Rag Doll and Cicada, as well as meta-technology that empowered individuals such as Spencer Young, Weather Witch, and Silver Ghost.
Cecile Horton
Cecile Horton (portrayed by Danielle Nicolet; main: seasons 5–9; guest: season 1; recurring: seasons 3–4) is the Central City district attorney and a close friend of Joe West. She would give occasional legal advice to Joe in season one.
In season five, Nicolet is promoted to series regular.[20] She and Singh later discover that Officer Jones sold out some metahumans to Cicada and have him fired and arrested.
Cecile is loosely based upon the comic book character of the same name, the attorney that defended the Silver Age Flash during his trial for the murder of Professor Zoom. She first appeared in The Flash #332 (Apr 1984).[21]
- Nicolet also portrays the Reverse-Flashpoint version of Cecile.
Ralph Dibny / Elongated Man
Ralph Dibny (portrayed by Hartley Sawyer; main: seasons 5–6;[22] recurring: season 4) is a metahuman with the ability to stretch his body to superhuman lengths and sizes.[23][24] This version was a police detective for the Central City Police Department until Barry Allen discovered that he had committed perjury by planting evidence. After Dibny was ousted from the police force, he became a private investigator specializing in infidelity cases. He acquires his elastic powers after the Thinker manipulates Team Flash into opening a breach, which exposed Dibny to dark matter. After discovering Dibny's powers, Allen takes him to S.T.A.R. Labs to stabilize. Deciding to give him a second chance after hearing he only planted the evidence because he was certain that the suspect was guilty but was unable to prove it, Allen adds Dibny to the S.T.A.R. Labs team and helps him become a superhero. Over the course of the season, Dibny substitutes for Allen while the latter serves time in prison, but the media sees him as a joke and initially dubs him the "Stretchy Man" before calling him Elongated Man due to a misunderstanding. Dibny also develops the ability to morph into other people, which he uses to free Allen from prison. In season five, Dibny launches an investigation into Caitlin Snow's childhood and helps Team Flash combat the serial killer Cicada. In season six, Dibny is hired to find Sue Dearbon and eventually finds Dearbon, only to learn she is a thief. Due to this, he becomes inspired to reform her, which he eventually succeeds in. Prior to and during the beginning of season seven, Dibny and Dearbon went "way off" the grid in light of Eva McCulloch framing the latter for murder. They return to assist Team Flash in their final confrontation with McCulloch, but Dibny suffered serious burns while raiding a Black Hole facility off-screen and is forced to wear a mask to protect himself. Once Dearbon is exonerated following McCulloch's defeat, she and Dibny leave to travel the world and stop criminal organizations.

Orlin Dwyer gets his abilities after being struck by a fragment of the Thinker's satellite, with the same incident leaving his niece Grace in a coma. Dwyer turns the fragment into a dagger that is capable of nullifying metahuman powers and which he has telekinetic control of. Having lost his sister (Grace's mother) in an earlier metahuman incident, combined with the Thinker's worldwide assault, leads to Dwyer developing anti-metahuman sentiment and he vows to exterminate all metahumans, including himself once he is finished. Dwyer appears throughout the fifth season, attacking and killing metahumans, with Team Flash dubbing him "Cicada". Secretly, Dwyer is aided by Dr. Ambres, who looks after not only him, but also Grace.

Allegra Garcia (portrayed by Kayla Compton; main: seasons 7–9; recurring: season 6) is a young metahuman with abilities based on the electromagnetic spectrum who wants to become a reporter ever since she saw Iris' article on the "Streak" (the latter's original name for the Flash). Despite coming from a criminal background and having been previously incarcerated in Iron Heights, Cecile was able to help Allegra turn her life around. After an attack by her metahuman cousin, Esperanza, whose attacks Allegra had been framed for, she got a job interning at the Central City Citizen. Allegra would later go on to investigate the mysterious organization that turned Esperanza into a killer and help Team Flash stop Bloodwork from turning Central City into his zombie-like minions.

While getting a scan of her, Mark improved his cryo-bracelets by the time Frost showed up. Both of them engaged in an ice battle before Frost took advantage of her ice healing to wound Chillblaine with an icicle. Flash and Allegra arrive where Flash quickly patches him up and has him cuffed. It was mentioned that Chillblaine was incarcerated at Iron Heights. During the storm caused by Nora, Chillblaine is among the inmates that escape and is defeated by Frost. When Frost encounters Chillblaine again in an alley, he shows her a news article that states that he got out upon handing over certain information to the authorities. After he was wounded by some thugs, Chillblaine was taken to S.T.A.R. Labs by Frost who healed his injury. Upon receiving his cryo-bracelets back, Chillblaine assisted in the fight against the Godspeed clones. Following the battle, Chillblaine snuck away.

Executive producer Andrew Kreisberg said, in season one "with the Reverse-Flash, we just modulated Tom Cavanagh's voice, and this year we wanted to do something a little bit different [for Zoom]. Part of the mystery of the season is who or what is underneath the Zoom outfit, and so we wanted to do something like James Earl Jones as Darth Vader — this iconic voice coming out of this mask."[61] Hunter was a traumatized child (portrayed by Octavian Kaul[62]) that witnessed his mother's murder at his father's hands which triggered his bloodlust as a serial killer before he gained his powers from the particle-accelerator explosion on Earth-2. Dissatisfied, he sought to increase his speed with the Velocity serum but soon discovered it carried a fatal illness. Searching for a cure, he traveled the multiverse and captured Jay Garrick. Unsuccessful in stealing Jay's speed to cure himself, Hunter kept Jay imprisoned with a speed-dampening mask. Inspired to be both hero and villain, he used Jay's name as the fraudulent Flash of Earth-2 to instill false hope which he would take away as Zoom. Discovering Earth-1, he plotted to increase Barry's speed and then steal it, sending various metahumans from Earth-2 to fight the Flash while also infiltrating the team as Jay. Zoom extorts Harry Wells into physically stealing Barry's speed by kidnapping Jesse Wells. He also becomes Caitlin Snow's love interest. After succeeding in stealing Barry's speed, Zoom brings his army of Earth-2 metahumans to conquer Earth-1 and construct a device capable of destroying the other Earths in the multiverse, to ensure he remains the only speedster. Hunter seeks to corrupt Caitlin's mind into being like Earth-2 Killer Frost and then Barry's by killing Henry in the same spot Eobard killed Nora, convinced that they are similar because of their childhood traumas. However, Barry ultimately bests Hunter in their final fight before two Time Wraiths arrive to punish him for his crimes against the timeline; they transform him into the corpse-like Black Flash enslaved to the Speed Force. Subjugated to the Time Wraiths, the Black Flash made occasional appearances in season three, such as to hurt Savitar before being killed by Earth-1 Killer Frost.

Hunter Zolomon held Jay captive in a failed attempt to harness his speed before becoming inspired to take up his persona and falsely operate as the Flash of Earth-2; even going so far as to use Jay's name. To keep him from escaping, Zolomon forced Jay to wear a mask that suppressed his speed and prevented him from talking. After Zoom's defeat, Barry rescues Jay, who soon returns to his Earth. Jay adopts Hunter's Flash helmet as a symbol of hope, taking satisfaction in taking something from Zoom as the villainous speedster had done to him.[65] Jay later learned from Harry Wells that Henry Allen is his doppelgänger and Barry is Henry's son. Knowing this, Jay watches over Barry as a sympathetic yet stern mentor, and a friendship develops. After undoing Flashpoint and trying to fix the mistakes left in its wake, he explains to Barry that time travel can have adverse consequences and that Barry must live with these mistakes. Jay also helps Barry come to terms with Henry's death and in battling Savitar. While they do banish Savitar to the Speed Force, Savitar later escapes, with Jay taking Savitar's place. After being freed, Jay joins Team Flash in the final battle to defeat Savitar. Jay later returns to help Barry use Flashtime, and reveals that he plans to retire and is training a protégée to become his successor as the Flash.
By season six, Jay has retired and settled down with his wife Joan. Barry does talk to him about the upcoming Crisis that is occurring in the Multiverse.
In season seven sometime after the Crisis, Jay is now living on Earth-Prime in Keystone City and regains his speed powers with the help of Joan. Before he can join the fight against the Godspeed Drones in Central City, he ends up taken captive by them to draw Bart out. It is revealed that the future of 2040 Jay Garrick helps mentor Bart Allen, and he gets killed by Godspeed, which makes Bart swear revenge to kill Godspeed/August Heart, not realizing that the real August Heart is comatose and that the people who killed Jay were actually Godspeed drones. Flash and Nora were able to rescue Jay and Bart with help from Mecha-Vibe. Jay later helped out in fighting the Godspeed Drones. Following Godspeed's defeat and Eobard Thawne getting away, Jay and Joan were present when Barry and Iris renew their vows.
In season eight, Jay's death in 2040 was erased upon Godspeed's death. Unfortunately, an event has erased Joan as Jay is married to a woman named Rose causing Nora and Bart to find the time anomaly responsible on December 31, 2013. After Nora and Bart fixed the timeline, Jay's marriage to Joan is restored as Jay mentions to Bart and Nora about his own time-travel adventures like one where he fought Nazis in World War II. Before departing, he mentions his upcoming meeting with President Lex Luthor. Jay and Joan from 2040 help Joe find Iris in the time stone that Darhk gave Joe. He later helps Barry in his fight with Thawne.
Based on the DC Comics character of the same name.
- Regarding the difference in his portrayal of Garrick over Allen, Shipp "figured Jay is my version of Barry" from the 1990 series, adding, "I went back and I watched a couple of episodes of the 1990–91 version to kind of remind myself what I did. [Jay] is much more reminiscent of my Barry Allen from 25 years ago than my Henry Allen. I went back and I was amazed how much attitude my Barry Allen had in some situations. I went back and I picked up that thread and I brought it forward 25 years, and tried to weave it in."[66]
- Shipp later reprises his role of Barry Allen from the 1990 television series in the crossover "Elseworlds". It is also revealed that the series is situated on Earth-90 and therefore like Garrick, this Flash is also Henry Allen's doppelgänger.

She believes that having superhuman power brings out the best or the worst in people, and acknowledges the Flash's heroism. Her hatred for Mark stems from survivor's guilt; when she was a teenager, she was supposed to make the deposit at the bank where her father died. When Patty gets her chance at revenge on Mark, the Flash persuades her to choose justice over vengeance. She leaves Central City to pursue her studies in the Forensic Science program at Midway City University. She also deduces Barry's secret identity and offers to stay if Barry confirms his feelings for her, but Barry admits nothing, not wanting to stop Patty from pursuing her studies.
