List of The Flash characters
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 is currently in its sixth season. The series is a spin-off from Arrow, a show 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 Flash.
The second season sees Barry and his allies dealing with the ramifications of their fight 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).

Main characters
Barry Allen / Flash
Bartholomew Henry "Barry" Allen (portrayed by Grant Gustin; season 1–present) is the main protagonist of the series. He is an awkward assistant crime-scene investigator (CSI) for the Central City Police Department (CCPD) who moonlights as the Flash. Barry is traumatized as a child (portrayed by Logan Williams) when his mother, Nora, is murdered by the Reverse-Flash. His father, Henry, is framed for the crime. Joe West becomes Barry's adopted father, and Barry tries to discover what happened that night. He first appears in Arrow, personally investigating a superhuman-related crime in Starling City. Barry is a fan of the Arrow's exploits and learns Oliver Queen is the vigilante; they become good friends. Sometime after Barry returns to Central City, he is struck in his laboratory by lightning which was affected by dark matter from the explosion of the S.T.A.R. Lab's particle accelerator.
In season one, Barry awakens from a nine-month coma and finds himself with superhuman speed. He uses his new powers to fight crime and hunt other metahumans in Central City as a masked superhero known as the Flash while he tries to identify his mother's murderer. He reveals his feelings for his childhood friend Iris West, complicating a friendship with Eddie Thawne. Barry learns from a 2024 newspaper in the Time Vault at S.T.A.R. Labs that he may eventually marry Iris. He becomes good friends with Cisco Ramon, Caitlin Snow, and his idol and mentor Dr. Harrison Wells on missions. Although Wells advises Barry on how to adapt and increase his powers, Barry becomes suspicious of Wells, especially his knowledge on speed is much greater than the scientist should know, and eventually learns his mentor is Eobard Thawne (a.k.a. Reverse-Flash) in disguise. After Wells is unmasked, Barry is told about Thawne's plan to use the Flash's speed and the particle accelerator to generate a portal to the future (allowing Barry to return to the night of Nora's murder to prevent). Barry travels back in time, but is warned by his older self not to interfere. As a result, he lets time run its natural course but uses his time-traveling to say a final goodbye to Nora before passing away. Barry returns to the present and fights with the Reverse-Flash, stopping him from returning to the future. Although Barry is almost killed, Eddie sacrifices himself to destroy Thawne. This creates a miniature black hole, which Ronnie Raymond stops with his own life.
In season two, Barry is reclusive after Eddie and Ronnie's deaths, until a near-death experience convinces him to work with his friends again. He discovers his former mentor's recorded confession of Nora's murder that clears Henry of all charges, with Barry inheriting S.T.A.R. Labs' fortune and resources. Though rich, Barry chooses to continue working for CCPD while using Wells' money to fund his and his allies' activities. Barry and his team soon learn of the multiverse when metahumans from Earth-2 target him under orders from Zoom, receiving aid from Dr. Harrison "Harry" Wells of Earth-2. Barry struggles with his choice to not save Nora and his hatred of Eobard, gradually accepting Harry as a friend upon learning that Harry is trying to save Jesse Wells. The group are aided by Jay Garrick before they learn that the Flash of Earth-2 is actually a time remnant clone of Hunter Zolomon (a.k.a. Zoom) stealing Barry's Speed Force to cure a terminal illness. After sacrificing his powers to save Wally West from Zoom, Harry helps Barry recreate the events which gave him his speed, but Barry disappears into the Speed Force as it helps him move on from Nora's death. After returning and defeating Zoom's army, Barry is forced to watch Henry's death at Zolomon's hands in his childhood home. He avenges his father by luring the Time Wraiths to Zolomon to be dragged into the Speed Force while being transformed into the Black Flash. After freeing the real Jay Garrick (Henry's Earth-3 counterpart), Barry goes back in time to avert Nora's death without considering the consequences.
In season three, Barry creates the new "Flashpoint" timeline in which he is no longer the Flash. In this timeline, Barry is a CSI without any connection to the West family. Barry's memories are overwritten by the new timeline along with losing his powers, forcing Barry to release the Reverse-Flash in order to restore the timeline. Barry learns his actions have made vast differences to the timeline and he goes back in time again in an attempt to further restore the original timeline. Garrick stops Barry and convinces him to live with his mistakes from creating the "Flashpoint" timeline. As Barry accepts Wally's transition into Kid Flash, Barry struggles with the temptation to use his powers for personal gain. His struggles worsen upon learning Savitar's identity is a time remnant clone of a future version of himself. After his rogue time remnant is killed, Barry takes Savitar's place in the Speed Force prison to atone for causing the events to have occurred. He appoints Wally as the new Flash before taking his leave.
In season four, Barry stranded in the Speed Force for six months until being freed after Cisco builds a device mimicking his essence so that it can take his place there. Initially, he apparently lost his sanity due to his time spent in the Speed Force. But after Iris is kidnapped by a Samuroid sent by a mysterious party, Barry rescues Iris and his health is restored. He claims that has no memories of his initial madness. Barry and the team later realize that the party who sent the Samuroid is stalking them and had strategically manipulated events surrounding Barry's return, creating twelve new metahumans in order to challenge them for a yet-to-be-known purpose. Barry discovers the culprit is Clifford DeVoe aka the Thinker. After defeating the invaders from Earth-X, Barry and Iris are married by John Diggle. However, DeVoe frames Barry for murder shortly afterwards; not wanting to risk compromising his loved ones and allies by revealing his secrets, Barry allows himself to be sentenced to life imprisonment at Iron Height Penitentiary by Judge Hankerson, staying in his late-father's cell. A month later, Ralph Dibny uses shapeshifting power to impersonate DeVoe and help clear Barry of all charges. Through his imprisonment, Barry learns that DeVoe needs to steal the bus metahumans' powers for his scheme. Barry is forced to take a leave of absence from the CCPD because of lingering suspicions and becomes a private investigator under Ralph. Barry also discovers he could lend his speed to people in near proximity, therefore letting them to enter his Flashtime.
In season five, Barry returns to the CCPD after Team Flash is able to prove the Thinker's existence, but is left dealing with a new unexpected problem when his daughter Nora West-Allen arrives from the future, wanting to change the events that lead to Barry's disappearance in the future. But because of his Flashpoint experience, Barry fears that Nora is making the same mistake as he did. Barry also facing the threat of metahuman serial killer Cicada inadvertently created by Nora's time traveling actions, therefore proves that his future daughter could potentially be a danger to everyone owing to the irresponsibility despite Nora's intentions; this fear is validated when Barry and Iris learn Nora's allegiance with Eobard Thawne. After briefly imprisoned Nora in the pipeline, Barry sends his daughter back home out of distrust. He later forgives her following a talk with Iris. After Cicada is defeated, Barry and Iris are devastated to find out that the new timeline has erased Nora. The two of them view a video that she left in her book thanking her for allowing her to experience being a superhero. The Time Vault newspaper about the upcoming crisis changes from 2024 to 2019. Following the Crisis, Barry finds that the Spectre's abilities that enabled him to enter the Speed Force have infected it. He works with Cisco and Nash to find a way to create a new Speed Force before he runs out of his super-speed.
- Gustin also plays his character's Earth-2 non-metahuman doppelgänger (a CSI at the CCPD and Ph.D. graduate who is married to Iris),[3] and a version of the Flash from an alternate 2024 who was broken from his battles against Savitar.
Savitar
Gustin also portrays Savitar (voiced by Tobin Bell in his exosuit and Andre Tricoteux in the character's initial portrayal), a temporal duplicate of Barry from a possible future (created due to a bootstrap paradox) and season three's main antagonist.[4] The time remnant, shunned by Team Flash, would name himself after the Hindu god of motion while establishing himself as the first metahuman in recorded history by using a powered exoskeleton and the Philosopher's Stone to enhance his abilities. As he is a clone of Barry's possible future self, Savitar is essentially what Barry would be if he gave into his dark impulses. Following his imprisonment in the Speed Force after a battle with the Flash in the 2020s, Savitar takes advantage of Barry's post-Flashpoint paradox to regain his freedom and cement his existence by killing Iris so that Barry would be in the right state of mind to ensure his creation. After H.R. Wells of Earth-19 averts Iris's death, Savitar makes two final attempts to preserve his existence, but is defeated by Team Flash and killed by Iris. His body fades from existence.

She accepts Eddie's death after seeing his video message (recorded by Barry when he is time-traveling) in which he tells her how happy she makes him. Iris reconsiders a relationship with Barry after he breaks up with Patty, and professes her love to him near the end of the season.
In season three, during the Flashpoint timeline, Iris assists Wally who fights crime as the Flash and no idea who Barry is. In the reset timeline, Iris reconciles with Joe after Barry reveals the changes. Iris and Barry begin their romantic relationship, but she wonders if she really is needed. Barry reassures her, saying that there would be no Flash without her. Iris and Barry become engaged after an encounter with Music Meister. An alternate future Iris is killed by Savitar, but Barry tries to prevent her murder. Ultimately, H.R. takes her place for Savitar to kill which changes the future.

However, the DeVoes frame Barry for murder shortly after, leading Barry's friends to try to prove his innocence.
In season five, Iris and Barry meet their future daughter Nora. Iris learns that her future self implanted a power dampener into Nora since infancy to hide her powers. She also discovers her future self, despite being a good mother, hid the fact that Nora's father was the Flash from her.

Iris wants to have a relationship with Nora and to avoid becoming the woman that the latter knew in the future. Following the defeat of Cicada, Iris and Barry are devastated to find out that the new timeline has erased Nora. The two of them view a video that she left in her book thanking her for allowing her to experience being a superhero.

After learning of Eva's plot as she made her way back to the real world, Iris is told that the real Kamilla and David Singh are in the Mirrorverse. Iris manages to find Kamilla as the neuro dissonance starts to worsen on her. She states that they need to find the real Singh. When she does find where Singh is, Iris suddenly disappears in front of Kamilla.
- Patton also portrays her character's Earth-2 doppelgänger, a detective for the CCPD who is married to Barry.[3] Mourning her father, Iris is comforted after she helps Team Flash deal with Zoom.
Caitlin Snow / Killer Frost / Frost
Dr. Caitlin Snow (portrayed by Danielle Panabaker; season 1–present) is a bioengineer who works at S.T.A.R. Labs and is the daughter of scientists Thomas Snow and Carla Tannhauser. She is based on the DC Comics character of the same name.
In season one, she provides the medical support for Barry Allen's team. Caitlin grieves her fiancé Ronnie Raymond,[5] who she lost in the particle accelerator explosion. After embracing her loss, she becomes more compassionate and kind. She discovers that Ronnie survived and merged with Professor Martin Stein into the metahuman Firestorm. Caitlin convinces Stein to let her team help separate the two, which is successful. Ronnie and Stein leave Central City following an encounter with General Wade Eiling. After Dr. Harrison Wells is exposed as the Reverse-Flash, Caitlin is skeptical until Cisco and Joe find the real Harrison's corpse and discover their mentor's true identity. Ronnie and Caitlin marry when her fiancé returns to help Barry and Oliver Queen against the Reverse-Flash.
In season two, Caitlin is widowed following Ronnie's sacrifice to stop the singularity. She works at Mercury Labs before returning to S.T.A.R. Labs to aid Barry against Zoom. She is not skeptical of Dr. Harrison "Harry" Wells of Earth-2 and begins a romantic relationship with Jay Garrick, the Flash of Earth-2. Caitlin and Harry develop "Velocity-6" to grant temporary speed, once she learns Jay is dying. It is perfected to Velocity-9, which repairs Jay's damaged cells and restores her love interest's speed. Caitlin is devastated when the team discovers Jay is actually Hunter Zolomon a.k.a. Zoom. Hunter abducts Caitlin to bring her to Earth-2. After meeting her doppelgänger Killer Frost and almost getting murdered, Hunter brings Caitlin to Earth-1 to watch Zoom conquer it. Hunter tries to manipulate her into turning evil, believing Caitlin has darkness inside her. Caitlin returns to S.T.A.R. Labs unharmed to aid Team Flash, though afterward she suffers acute stress disorder, seeing visions of Zoom.
In season three, she is a pediatric ophthalmologist in the Flashpoint timeline. In the reset timeline, Caitlin has developed cryokinetic abilities, which she has very little control over. Her lips turn blue and her hair becomes white, which prompts Caitlin to use power cuffs to dampen her powers. Cisco vibes her future as Killer Frost, and Caitlin reveals her powers to the team in which Barry blames himself for her condition afterward. Caitlin uses her powers to rescue Barry from Savitar, which worsens her condition. Her developing powers have psychological effects, which cause her to develop a form of dissociative identity disorder. Despite Julian Albert's efforts, Killer Frost's personality takes over and aligns herself with Savitar after unmasking himself as a time remnant of Barry. Savitar has Killer Frost kill the Black Flash with her powers. However, Caitlin regains control over herself and helps Team Flash against Savitar. Despite Julian and her mother developing a cure for her condition, Caitlin leaves to 'find herself'. In an alternate 2024, Killer Frost is a metahuman prisoner.
In season four, Caitlin helped Cisco bring Barry back from the Speed Force. She has better control of her powers which she can suppress at will. She struggles for control with her Killer Frost personality as a result of taking the cure, which partially worked. Caitlin also has problems with the city's criminal element after working for metahuman criminal Amunet Black when Barry was in the Speed Force. Iris helps both of Caitlin's personalities accept each other. However, Caitlin loses her powers after a fight with Clifford DeVoe who tells her to thaw. Following a fight with Siren-X, Caitlin sees in an analysis that Killer Frost is still in her and works to find a way to bring her out again. In the meantime, she makes use of a cryonic weaponry from Cisco which simulates the use of her lost powers. Amunet theorizes that Caitlin was unable to access Killer Frost due to the placebo effect. Following the defeat of Norvak, Caitlin tells Joe West of this theory and plans to test it out. Later on, Caitlin gets Cisco to help with a memory where it recapped to her that she first turned into Killer Frost at a young age, therefore she has been already a metahuman long before the particle accelerator explosion and Barry's time traveling actions are possibly not responsible for her condition as previously believed.
In season five, as Caitlin works to restore her Killer Frost persona, she discovers that Thomas may still be alive. In addition, Caitlin suspects that her parents secretly are aware of the developments of her cryokinetic powers. Caitlin becomes Killer Frost again during the fight with her father's Icicle form, therefore Caitlin inherited her powers from Thomas; she would be Killer Frost anyway even if Barry resisted temptation of manipulating the timeline. Caitlin received her powers after her father tries to cure her ALS with cryogenic treatments, and his alter-ego named her metahuman persona 'Khione', after a nymph from Greek mythology. After Icicle escapes, Caitlin is shown an analysis where it was revealed that DeVoe used Brain Storm's power and not Melting Pot's power to suppress Killer Frost. She also discovers that, despite being a metahuman, her powers are not originated from the dark matter, and this gives her immunity to Cicada's power dampening dagger due to it can only nullify dark matter-powered metahumans' powers. Using a mental device on her forehead, Caitlin hears Killer Frost's voice as she states that they got a lot of catching up to do. Killer Frost later assists in the fight against the different Cicadas with the second one killing her father.
During the sixth season, Caitlin works to give Killer Frost a chance to explore her own life rather than just bringing her out during moments of crisis, letting Frost control their shared body so that she can explore her own interests. Caitlin is also troubled by her colleague, Ramsey Russo, whose attempts to cure himself of a rare disease causes him to mutate into a dark-matter-empowered monster who nearly takes control of Central City before Barry manages to defeat him. After the Crisis concludes with Barry surviving despite predictions of his death, Caitlin assists him in attempts to find a way to sustain his speed after it is revealed that the events of the Crisis essentially infected the Speed Force with Spectre's energies. Cisco and Ralph find Caitlin suffering from a hypothermic reaction while recuperating from a battle with Sunshine. Once she counters it, Caitlin decides to visit her mother. Frost was unable to go along with this plan, by Ralph was able to persuade her to visit Caitlin's mother. Carla shows up to run a short test on Frost before they leave for the arctic.
- Panabaker also portrays her character's Earth-2 metahuman villainess, known as Killer Frost, the wife of Deathstorm (Ronnie Raymond of Earth-2) and works for Zoom along with Reverb.[3] She did not finish medical school and became a criminal. 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.
Eddie Thawne
Edward "Eddie" Thawne (portrayed by Rick Cosnett; main season 1; guest seasons 2–3) is a CCPD detective who transferred from Keystone City.
In season one, Eddie is Joe West's partner and Iris West's boyfriend. He is initially jealous because of Barry Allen's childhood bond with Iris. Eddie is suspicious of Barry's true feelings for Iris despite denials, though Barry and Eddie do eventually end up good friends. Eddie teaches Barry how to box, which (in addition to Oliver Queen's trainings) helps Barry be a capable combatant. Eddie initially sees the Flash as a menace and is head of a task force dedicated to the Flash's capture. He changes his perception of the Flash after a near-death experience with the Reverse-Flash. He later learns of Barry's secret identity and helps in an investigation of Harrison Wells as the Reverse-Flash. Eddie also discovers that he's a forefather of Eobard Thawne and that Iris may eventually marry Barry. But after a conversation with Martin Stein, Eddie realizes that the future is not set and chooses to stop the Reverse-Flash by killing himself, dying in Iris's arms while erasing his sociopathic descendant from existence. His body is sucked into a wormhole caused by Eobard's manipulations.
In season two, Eddie briefly appears in a vision as a result of Barry's guilt towards his death, and a memorial is set up in the precinct in his honor. Eddie later appears again when Barry travels back in time to season one's time. Barry makes a video message with Eddie so that Iris can have closure from his death and move on.
In season three, the Speed Force uses Eddie's form to help Barry realize the true meaning of sacrifice.[6]
The character's name is referred on Earth-2 from a list of contacts on a phone at Barry's and Iris's home, implying his Earth-2 doppelgänger's existence.[3]
Cosnett was originally slated to portray Jay Garrick in the pilot before the character was changed to Eddie Thawne.[7]
Cisco Ramon / Vibe
Francisco Baracus "Cisco" Ramon (portrayed by Carlos Valdes; season 1–present) 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.
In season one, Cisco is a scientist at S.T.A.R. Labs who has a very relaxed comedic wit as he regularly quotes or alludes to science fiction films and thrillers. He likes to nickname the metahuman villains they face and comes to consider this his own personal privilege. He develops equipment and an arsenal for Barry and his vigilante allies. Cisco forms a friendly bond with Ray Palmer (the Atom) because of their genius intellects, and is an admirer of Dinah Laurel Lance (Black Canary). Cisco is on bad terms with his brother Dante. Despite his close friendship with Barry, Cisco is afraid of the metahumans and fears that his friend may go rogue like his enemies. He develops various measures, including cryonic and heat guns, to counter the Flash's powers, but they are stolen by criminals Leonard Snart and Mick Rory for that very purpose. Although Wells considers him a surrogate son, Wells kills Cisco for discovering Wells' true identity. Barry later resets the timeline. but Cisco retains the memory of his murder and the knowledge of the Reverse-Flash's true identity within his subconscious. Cisco later learns that this is because he was also affected by the particle accelerator's explosion, becoming a metahuman with the ability to see into alternate timelines and realities.
In season two, Cisco is a technical advisor and metahuman task force armorer for the CCPD, building means to counter super-criminals. He frequently works with Joe West. Cisco's metahuman abilities develop further, allowing him to see visions (or vibes) including precognition. He uses his abilities to locate Earth-2 metahumans through touch, though he is not yet in full control of them. Martin Stein is the first to discover his secret. Cisco is forced to reveal his powers to the team because of Harry Wells of Earth-2. Cisco adopts the codename "Vibe" and receives a retrofitted visor that can help him control his powers. He initially struggles to trust Harry due to his experience with Eobard, but he realizes that Harry is not like Eobard. He still cannot get along with Harry due to contrasting personalities, and admits that Eobard was a nicer guy. He briefly dates Kendra Saunders. After encountering his Earth-2 doppelgänger, Reverb, Cisco fears that he, too, is on the path to becoming a villain. However, Cisco works to harness his powers for heroic purposes. Cisco also meets his brother's Earth-2 doppelgänger, Rupture, after Zoom frames him for Reverb's death. After this, Cisco and Dante reconcile. During an encounter with the Black Canary's Earth-2 doppelgänger, Black Siren, Cisco briefly uses a powerful sonic attack against her. He also develops the ability to open portals to parallel universes.
In season three, Cisco is a billionaire tech magnate in the Flashpoint timeline, profiting by his inventions but also secretly helping Flash (Wally West) and Iris. In the reset timeline, Cisco is coming to terms with his brother's death, but his grief worsens when Cisco learns that Barry was inadvertently responsible for Dante's death: Their friendship is strained for a while. However, Cisco and Barry reconcile after Cisco inadvertently alters history for the worse during the Dominators invasion. Cisco starts to use his powers more, but he refuses to utilize their destructive potential as Reverb did. He gains confidence that he is not on the same path as his Earth-2 doppelgänger and builds a prototype suit prior to Dante's death. Cisco's refusal to fully use his powers against Killer Frost gives her a psychological advantage over him. His rejection of his dark side eventually inspires Caitlin to do the same. Cisco shares a budding romance with Cynthia Reynolds (Gypsy), a metahuman bounty hunter from Earth-19. Cisco also struggles to build a friendship with Harrison "H.R." Wells from Earth-19, not because of his experience with Eobard Thawne but because both he and Harry see him as a nuisance. In an alternative version of 2024, Cisco lost his hands, and thus the use of his powers, after the fight with Killer Frost. He replaced them with cybernetic prostheses and became dejected after Savitar's attacks leave Central City without a sense of hope.
In season four, Cisco succeeds in bringing Barry back from the Speed Force, after six months of building a device that mirrors Barry's essence—with help from Felicity, Harry, Caitlin, Tracy, Christina "Tina" McGee, and Curtis Holt. After Barry is sentenced to prison because the DeVoes framed him for murder, Cisco works with Ralph Dibny, who substitutes for the Flash as the Elongated Man. Cisco and Gypsy break up when they realize their careers and lives are keeping them apart.
In season five, Cisco fakes his superhero alter-ego's death after Cicada's attack. He is forced to take a leave from heroics and is temporarily unable to use his powers because traces of energy from Cicada's dagger have nullified them. In time, before his powers are restored, Cisco enjoys being an ordinary individual who relies on his intellect. With Ralph's help, Cisco begins to move on from his break up with Gypsy and sees other people. At the end of the season, Cisco takes the metahuman cure he developed to get rid of his powers so he can have a normal relationship with his new girlfriend Kamilla.
In season six, Cisco has adjusted to civilian life and continues working as a tech expert for S.T.A.R. Labs and Central City Police Department. When Barry looks into the future, he sees Cisco as Vibe; which would later come true during the Crisis, when the Monitor restores his powers so he can help avert it. Following the universe undergoing significant changes as a result of the Crisis, Cisco's depowered state is restored and temporarily leaves Team Flash to catalogue said changes. He was able to find that some of the people they knew are alive and Atlantis is on Earth-Prime. Cisco works with Barry and Nash to find a way to create a new Speed Force. When it comes to finding a component for a perpetual motion machine that can free Iris, Kamilla, and Singh from the Mirrorverse, Cisco states that he saw one like it in Atlantis and departs to obtain it.
- 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.
Harrison Wells
Harrison Wells (portrayed by Tom Cavanagh; season 1–present) is, on most earths in the Multiverse, the mind and money behind the S.T.A.R. Labs particle accelerator in Central City.
In season one, Eobard Thawne kills Harrison Wells and assumes his identity. He then creates a particle accelerator that releases dark matter energy in Central City, killing several civilians and granting various individuals metahuman abilities, including Barry Allen. Nine months later, Wells, along with Cisco Ramon and Caitlin Snow, helps develop Barry's powers as the Flash and mentors him in pushing his speed to the limit to come up with novel solutions to take down metahuman criminals. Eventually, Thawne is exposed and his plans are foiled when he is erased from existence after his ancestor Eddie Thawne commits suicide, though the Reverse-Flash's existence lingers to preserve the timeline. In season two, Eobard's last will as Harrison Wells contains a recorded confession for Barry that clears Henry of all charges. Thawne reappears in later seasons, still wearing Wells' face.
Season two features the Earth-2 version of Dr. Harrison "Harry" Wells, the father of Jesse Wells. He, like Eobard, used an exploding particle accelerator to create metahumans, including the psychopathic serial killer Hunter Zolomon as the rogue speedster Zoom. Harry refused to take responsibility while making a profit by developing metahuman detector technology. But when Zoom kidnaps Jesse, Harry travels to Earth-1 to assist Barry in the fight against Zoom's metahumans and to locate Jesse. Team Flash, specifically Cisco and Joe, distrust him because of the prior betrayal by Eobard, and Harry himself is mistaken by people, unaware that Eobard's actions ruined his Earth-1 doppelgänger's name and legacy. Harry meets the Reverse-Flash's younger self, suspecting that the encounter between them is what caused Eobard's future actions towards his Earth-1 self and lead Harry to hate Thawne. Harry is extorted by Zoom into developing a device to steal the Flash's speed for Zoom in exchange for his daughter's life, a feat that even the Reverse-Flash had failed to achieve. But Harry confesses to his collaboration with Zoom and gains Barry and Cisco's help rescuing Jesse from Earth-2; Harry and Jesse then seek refuge on Earth-1. After Barry's speed is sacrificed to Zoom to save Wally West, Harry recreates a miniature particle accelerator to help Barry regain these powers. Although the accelerator explosion causes Barry to disappear, and its dark matter affects both Wally and Jesse, Harry eventually locates Barry at the Speed Force; with Cisco and Iris' help, Harry brings Barry back and Barry wakes Jesse from the coma. After Zoom's defeat, Harry and Jesse return to Earth-2 with Jay Garrick, promising to help the Flash of Earth-3 return to his own Earth. Harry returns early in season three after Jesse is revealed to have developed super-speed as a result of the accelerator, but Harry asks the team talk his daughter out of pursuing heroics. After Barry and Jesse are forced to team up, Harry becomes more supportive of it. Harry helps Joe protect Iris after they arrive on Earth-2 to hide from Savitar, but they fail to stop her kidnapping. Harry despises his Earth-19 doppelgänger, H.R. Wells, who he considers a moron, but comes to respect H.R. after learning of his sacrifice for Iris. In season four's season premiere, it is revealed that Harry was one of the scientists who helped Cisco develop a device to take Barry's place in the Speed Force. Harry visits Earth-1 again after an argument with Jesse, and helps the team fight Clifford DeVoe, augmenting his intelligence with dark matter to oppose DeVoe before it is revealed that the use of dark matter damaged his brain. He returns to Earth-2 after DeVoe's defeat, his intelligence restored to a normal human level after further exposure to dark matter.
Season three introduces his Earth-19 counterpart, Harrison "H.R." Wells. H.R. is one of several versions of Harrison Wells that finds the cryptogram sent by Harry through the multiverse and expresses interest in aiding Team Flash. Cisco determines that H.R. is not a scientist; H.R.'s scientist partner at S.T.A.R. Labs, Randolph Morgan, was the one who solved Harry's cryptogram for him. Barry suggests letting H.R. stay a few weeks and he proves his worth by helping form plans and locating super-criminals; like Harry and Eobard, H.R. is a skilled organizer, businessman, and entrepreneur. He trains Wally to be a hero and, after discovering how many criminals breached the facility, strives to transform S.T.A.R. Labs into a museum to maintain Team Flash's cover. Gypsy, an enforcer from Earth-19, arrives to retrieve H.R. on charges of crossing dimensions, but is defeated by Cisco. In the battle against Savitar, H.R. sacrifices himself by disguising himself as Iris and taking her place to be killed by Savitar. In the alternate 2024, H.R. was a successful novelist.
Season five introduces the Earth-221 version in the form of Harrison Sherloque Wells, a detective who has solved cases across the multiverse. He is 'hired' by Team Flash to investigate the mystery of the metahuman serial killer, Cicada, staying on Earth-1 after his initial deductions prove incorrect as Earth-1 Cicada has a different secret identity compared to the other versions Sherloque had previously captured. During his stay, he becomes suspicious of Nora West-Allen, and secretly investigates the young speedster; discovering her allegiance with his Earth-1 doppelgänger's impostor and killer Eobard Thawne in the process. Sherloque has married the Renee Adlers of various Earths in the multiverse and eventually starts dating the Earth-1 version of her. He sends the Earth-1 Renee to his Earth to keep her safe from Cicada. After Cicada is defeated, Sherloque returns to his Earth to seek out Renee.
Season six introduces Harrison Nash Wells, a tech-wielding adventurer and "myth buster" from an unspecified Earth who's come to Earth-1 to find a substance called "eternium" as well as track the Monitor so he can expose him as a false god. He doesn't seem to enjoy company as he sees the Council of Wells as "jerks", initially refused to work with Team Flash, and believes putting faith in others is too dangerous. Despite this, he was willing to offer his services to them in exchange for a device he claims only Cisco can build before quickly going off on his own once more. He would later begrudgingly work with Team Flash after they offer to help him, and claim he can save Barry from his prophesied death in the upcoming Crisis. Through their help, he's uncovered a wall that he says protects a portal the Monitor uses to hide out that Barry can't phase through due to it being laced with traces of eternium. Moments before Crisis takes place, Nash uncovers a wall covered in symbols before a voice offers him unlimited knowledge and power in exchange for worshiping it. Though he initially refuses, Nash ultimately relents after the voice appears to save him and is pulled into the second wall. When the Crisis begins, Nash reveals he was manipulated by the Anti-Monitor, who used him in his plot to destroy the multiverse. As a result of freeing the malevolent being, Nash was enslaved by him and transformed into a "Pariah"; cursed to bear witness to the multiverse's destruction as penance. Despite this, he was able to ensure the safety of seven heroes capable of stopping the Anti-Monitor before the god-like being succeeded. Once the Anti-Monitor is defeated and the multiverse is restored, Nash is restored to his pre-Crisis self, though he is later given his memories as Pariah so he'll never forget what he did.
Other versions of Wells appear in the episode "The New Rogues": a gunslinger variant named "Hell's Wells", a steampunk-styled scientist from Earth-17, and a French mime.
During the fourth-season episode, "When Harry Met Harry...", Harry creates the "Council of Wells", which consists of the smartest versions of himself from across the multiverse: Harrison Wolfgang Wells, a German author and scientist from Earth-12; H. Lothario Wells, a billionaire playboy from Earth-47; and Wells 2.0., a cyborg from Earth-22. Also shown is a wizard variant named "Wells the Grey" from Earth-13.
During a later fourth-season episode, "Harry and the Harrisons", Cisco creates the "Council of Harrisons" (consisting of the most empathetic versions of Wells from across the multiverse) to comfort Harry while he was losing his intelligence: Lothario Wells (who had been expelled from the Council of Wells), the Italian Sonny Wells of Earth-24, and the French poet H.P. Wells of Earth-25.
Harrison Wells is an original character created for the series while Eobard Thawne is based on the DC Comics character of the same name.[8]

Wally West / Kid Flash
Wallace "Wally" West (portrayed by Keiynan Lonsdale; main seasons 2–4; guest season 5–present) is Iris' unknown brother and Joe's son,[13][14] described as "a bit of a wayward kid who has some attitude problems and some authority issues and is quick with a sassy remark".[15] Based on the DC Comics character of the same name, the character is an amalgamation of his original interpretation and the interpretation that was introduced during DC's The New 52 relaunch.
Wally was born after his mother's abandonment of her family, leading Joe and Iris to be unaware of his existence for eighteen years. Wally first meets his father and sister during a Christmas party shortly before his mother dies, and he struggles to bond with Joe and Iris. He also forms a brotherly bond with Barry Allen, although he is suspicious of Barry's weird behavior. Formerly a drag racer, Wally is enrolled at the same university Iris attended, majoring in mechanical engineering. After repeatedly being rescued by the Flash, Wally becomes fascinated with the superhero and discovers that his father has a connection with him, but is unaware that he is Barry. He is inspired by both his father and the Flash to help people, and as a result becomes closer to Joe. Later, when Wally and Jesse Wells are locked in the Time Vault at S.T.A.R. Labs, they work together to escape but are accidentally affected by the dark matter released from the attempt to restore Barry's powers; his father and Barry suspect that Wally is turning into a metahuman after the incident. Eventually Wally discovers Barry's secrets when Zoom abducts and kills Barry's father, and fully accepts Barry after he rescues Joe from Zoom.
In the Flashpoint timeline, Wally is the Flash,[16] until he is badly injured by the rogue speedster Rival and Barry and Eobard Thawne reset the timeline. In the post-Flashpoint timeline, Wally struggles to become a speedster after witnessing Jesse becoming one. After Alchemy seeks Wally out, Wally learns of his alternate life and uses the villain's device to gain his speed. Wally then becomes a speedster after Caitlin stabilizes his metamorphosis, and he is eager to join Barry as his partner, Kid Flash, to both his father and sister's concerns.

In season six, Wally is revealed to have joined the peace corps, he also warns Barry about the Speed Force dying.
Lonsdale decides that he will not be returning full-time on season five, due to his desire to seek other acting opportunities.[18]
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.[14] Keiynan Lonsdale originally auditioned for Legends of Tomorrow to portray Jefferson "Jax" Jackson.[19]
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 season four's main antagonist.[20] Prior to his appearance, he was alluded to in season three by Abra Kadabra and Savitar as a powerful future adversary. Originally a mild-mannered professor who dreamed of expanding the way people think, Clifford DeVoe used the "thinking cap" his engineer wife Marlize DeVoe built on his specifications and powered it with the dark matter wave from the S.T.A.R. Labs explosion to boost his intelligence. It eventually rendered him paraplegic and with an advanced form of amyotrophic lateral sclerosis, Marlize developing a hoverchair to delay the affliction as he developed a god complex. Having deduced Barry's imprisonment in the Speed Force, the Thinker orchestrated events that to force the Flash's return while arranging the creation of twelve new metahumans on the bus directly exposed to the resulting dark matter wave. He then hunted them to acquire their powers for his own, being steps ahead of Team Flash as he used them to capture Kilg%re and Becky Sharpe and induct Ralph Dibny into their group while he personally captures the Weeper. Barry soon learns of DeVoe's existence, the villain accepting the "Thinker" moniker Vibe invented while continuing to be steps ahead of the group.
Using Amunet Black to acquire Dominic Lanse, DeVoe transfers his consciousness into the metahuman's body (Kendrick Sampson) to acquire his telepathy while using his lifeless original body to frame Barry for murder. This ultimately plays to his plan in causing an Iron Heights Prison breakout, acquiring Becky's body (Sugar Lyn Beard) and luck manipulation along with the powers of Kilg%re, Black Bison, and Dwarfstar while killing Warden Wolfe to Marlize's horror. This is the start of his personality changing for the worst as, showing indifference upon learning that Barry is exonerated, DeVoe places an extract of Weeper's tears in his wife's drink to make her more obedient. He later transfers his mind into the body of Izzy Bowin (Miranda MacDougall) to acquire her powers, leaving only Ralph and four more metahumans to capture. After proceeding to take the powers of Edwin Gauss (Arturo Del Puerto) as well as Melting Point and Null, DeVoe manipulates events that lead to him taking Elongated Man's body and thawing Caitlin Snow's Killer Frost form. He then uses Elongated Man's powers to shape his body into his own so that his wife can now love all of him. After raiding an A.R.G.U.S. facility, DeVoe begins to put his Enlightenment Satellite plan into action. With help from Marlize, his plot is thwarted while his host regains control of his body when Barry's conscience enters the Thinker's mind to help fight off, during which DeVoe's good side manifests as a corpse, showing that he was truly beyond redemption. With his original body dead and Marlize having destroyed every known means he has to sustain his survival, DeVoe no longer exists.
However, the Thinker's Enlightenment satellite plays a part in the origin of Cicada and the Meta-Tech which causes any item to grant anyone metahuman abilities.

In season one, Ralph's name was referred by Eobard Thawne of him being one of the victims killed by the particle accelerator explosion prior to the timeline change in season three. Dibny was a CCPD detective until Barry testified against him for tampering with evidence.
It is later revealed in season four that Dibny committed perjury out of a misguided sense of justice rather than a desire for personal gain: he feared a suspect would get away with murder, and thus planted fake evidence. Dibny then became a shady private detective specializing in infidelity cases. He was on the bus that was exposed to dark matter energy and became a metahuman and ally to Team Flash. After Barry is framed by Clifford DeVoe for murder and sentenced to life at Iron Heights without possibility of parole, Ralph substitutes Barry as Central City's new superhero Elongated Man, to continue Team Flash's fight against DeVoe and other criminals while working to free Barry. Posing as Clifford DeVoe, he appears before Judge Hankerson during Cecile and Iris' appeal, claiming that someone knocked him out and made him look dead. This statement convinces Judge Hankerson to exonerate Barry. Elongated Man's body is later taken over by the Thinker who stretches it into his own image. During the final battle with the Thinker, Elongated Man regains control of his body and helps defeat him.
In season five, Ralph begins an investigation into Caitlin's childhood past, and helps Team Flash against the serial killer Cicada. Ralph is the first to figure out Eobard Thawne's master plan, which earns him the praise of detective Sherloque Wells, who dubs him Team Flash's new master detective upon leaving Earth-1.
In season six, Ralph is hired to find a woman named Susan Dearbon by her parents, resulting in him traveling around the world to find her. In his encounters with her, Ralph learned from her that Black Hole is extoring her parents as she gives him a diamond that contains the information that he needs.

Ralph later visits Sue at where she's been hiding out and shows her an article where Eva pinned the blame of Carver's death on her.
Nora West-Allen / XS
Nora West-Allen (portrayed by Jessica Parker Kennedy; main season 5; recurring season 4) is introduced as a mysterious girl with super-speed.[26] She is first seen at the wedding of Barry Allen and Iris West and later interacts with each member of Team Flash throughout the fourth season, secretly helping Barry stop the Thinker's falling satellite at the end of the season. Afterwards, she appears at the party welcoming the daughter of Joe West and Cecile Horton, revealing herself as Barry and Iris' daughter from the future and stating that she has made a big mistake. While using her super-speed, she initially has both yellow lightning similar to Barry and purple lightning similar to Iris when she was briefly a speedster.[27]
Nora grew up without her father, while also not knowing that he was the Flash. She eventually begins working as a CSI like her father. After being struck by the villain Godspeed's lightning, Nora discovers she had a power dampening chip implanted into her in her infancy, which hid her speedster powers. This revelation, combined with Nora finding out the truth about her father, drives a wedge between her and her mother with Nora believing that she robbed her of the choice to pursue heroics. Nora seeks out Eobard Thawne at Iron Heights' death row, not knowing that he killed her paternal grandmother, and he eventually agrees to begin training her in her newfound powers. Becoming a superhero, she chooses the codename XS from her mother's nickname for her, owing to her tendency to do things in excess, and takes her mother's old purple jacket from Iris's short tenure as a speedster as a part of her costume. Thawne teaches Nora how to travel back in time so she could meet her father before his disappearance. In the present, Nora begins working alongside her parents, hunting Cicada as part of Team Flash. She bonds with both of her parents, while also secretly reporting back to Thawne at regular intervals. When she finds out the truth about Thawne, she briefly questions her partnership with him but chooses to continue. Though Nora spends months in the past, all of her interactions with Thawne take place within the same day in 2049.
Eventually, Sherloque Wells, who has been suspicious about Nora from the start, uncovers the truth about Nora and Thawne and forces her to come clean to her parents. Barry is particularly hurt by the revelation and sends Nora back to her time, warning her not to time travel again. However, Nora wants to finish the hunt for Cicada and asks Thawne to teach her how to tap into the Negative Speed Force to time travel without being detected by her father. Nora succeeds in tapping into the Negative Speed Force, which turns her lightning red, and returns to 2019. She teams up with the criminals Brie Larvan, Rag Doll and Weather Witch to steal a gun capable of destroying Cicada's dagger. After the others turn on Nora, she is saved by Barry, Iris, and Joe. Nora makes amends with her parents with Barry agreeing to use her and Thawne's plan to destroy the dagger, especially with Iris since remaining angry with her would be hypocritical as she also kept secrets. After the dagger is destroyed, Team Flash fights the released Thawne. Nora, corrupted by the Negative Speed Force, is about to kill Thawne but is stopped by her parents. A new timeline begins to push itself through, threatening to erase Nora. She refuses to return to the Negative Speed Force to save herself as it would corrupt her even further and is erased from existence. They find a video in Nora's diary where she thanks them for helping her see what it is like to be a superhero.
Later, in season six, Nora's message to her parents is destroyed by the Monitor in an attempt to dissuade Barry from fighting his predestined fate. Her parents, while anticipating that a version of her would be born one day, have difficulty coping with the realization that it would not be the same Nora. The two honor their daughter by recovering her speedster jacket.

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.
When it is discovered that Grace has also become a metahuman, Dwyer agrees to take the metahuman cure developed by S.T.A.R. Labs as it could also be used to cure Grace. After Dwyer has lost his powers, a new Cicada attacks S.T.A.R. Labs and abducts him; later revealing herself as an adult Grace, who has traveled back in time to finish her uncle's mission. Having had a change of heart, Dwyer tries to get Grace to abandon her plan, which leads to her killing him. While dying in Flash's arms, Dwyer tells him to save Grace. When Nora West-Allen enters Grace's mind in the season finale to convince her to take the metahuman cure, she is met by two Orlins; one that tries to kill her and another who supports her.

Eobard Thawne / Reverse-Flash
Eobard Thawne / Reverse-Flash (portrayed by Matt Letscher; Tom Cavanagh in Harrison Wells's form) is the time-traveling archenemy of Barry Allen and a future descendant of Eddie Thawne, based on the DC Comics character of the same name and is the main antagonist of season one.[43] In the 22nd century, Eobard was an amoral scientist obsessed with the Flash and desired to "become" his idol. Eobard duplicated the reaction and be a speedster, only to learn that he was destined to become the Flash's greatest enemy and grew to despise his idol. Eobard became the "reverse" of everything the Flash was and the two enemies encountered each other over years, neither strong enough to defeat the other. At one point, Reverse-Flash (who had traveled to 2024) vanishes with the Flash in the midst of a "crisis". Discovering the Flash's identity, Eobard murders Nora Allen after a failed attempt to kill Barry as a child, but loses his connection to the Speed Force and gets stranded in the past.
Flashbacks from season one reveal he takes on Dr. Harrison Wells's appearance and manipulates events in an attempt to return to his time period; Eddie sacrifices himself in the first-season finale, causing Eobard to be erased from existence. However, Eobard's existence survives this erasure. Eobard's first chronological appearance occurs during season two; the Reverse-Flash travels back in time to 2016, encountering the Flash for the first time (from Eobard's perspective). In the midst of using Tina McGee's "speed machine" construction to return to his time period, he suffers a severe beating from the Flash. While being briefly imprisoned at S.T.A.R. Labs, he comes to know about some of his own future actions after interactions with the Flash, Cisco Ramon and Harry Wells, but is sent back home to prevent a time paradox. In the second-season finale, the Flash travels back to prevent the Reverse-Flash from murdering Nora, altering significant events.
In season three's premiere, Eobard is imprisoned by Barry while they're both in the Flashpoint timeline. Trying to convince his nemesis to restore the reality they both know, Barry gives in after realizing the new timeline's dangers. The Reverse-Flash is released to murder Nora, which supposedly "fixes" the timeline. Eobard then brings Barry back to a slightly different timeline and leaves but not before taunting his nemesis, implying his awareness that the timeline is not reset exactly. It is later revealed that this iteration is a temporal duplicate of the original (who subsequently appears on Legends of Tomorrow to rewrite reality to stabilize his existence but is erased from existence again by the Black Flash).
In season four, Eobard miraculously returns during the "Crisis on Earth-X" crossover, once again wearing Wells' face. Having allied himself with Nazi-ruled Earth-X's Dark Arrow (Oliver Queen's doppelgänger) and Overgirl (Kara Danvers' doppelgänger), he returns to Earth-1 in an attempt to take it over, but disappears after his accomplices are killed.
In season five, it's revealed Eobard's powers are from his own version of the Speed Force (the Negative Speed Force) which Barry cannot detect when he time travels and is immune to timeline changes, thus how he survived his erasures. Now on death row at Iron Heights in 2049 where he has been for 15 years, he is the secret mentor of Nora West-Allen / XS with their relationship having begun when he helped defeat Godspeed. He guides Nora throughout XS' and Team Flash's struggle against the two Cicadas, eventually teaching Nora how to tap into the Negative Speed Force. After learning of Eobard's involvement and returning Nora to 2049, Barry confronts Eobard at his cell, stating that he is about to get what he deserves. Throughout their interactions, Eobard seems to have developed some feelings for Nora and Iris West-Allen comes to believe that he is trying to redeem himself with Barry eventually accepting his plan of how to destroy Cicada's power-dampening dagger. It is then revealed that the same dagger is being used in 2049 to dampen Eobard's powers. When Cicada's dagger is destroyed, Eobard is released. He is subdued by Team Flash, but manages to escape after the group is preoccupied trying to save Nora from being erased by a new timeline.
In season six, due to the Crisis however, he was fused with Nash Wells. In the months following the event, he slowly asserted control over Nash's body and regained his connection to the Negative Speed Force. However, Team Flash caught on to him before the latter, and built a device to "exorcise" him from Nash. Despite his best efforts, Thawne was defeated once more and left without a body to possess.
He is based on the DC Comics character of the same name.

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."[60] Hunter was a traumatized child (portrayed by Octavian Kaul[61]) 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 and summons two Time Wraiths 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.
Jay Garrick / Flash
Jay Garrick (portrayed by John Wesley Shipp) is the Earth-3 version of Barry's father Henry Allen. 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.[64] 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. 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."[65]
- 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. Later, in the crossover "Crisis on Infinite Earths", he sacrificed himself destroying the Anti-Monitor's anti-matter cannon; taking Earth-1 Barry's place after the Monitor specified a Flash must die during Crisis.
Patty Spivot

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. Patty surreptitiously does get Barry to reveal the Flash persona to her as she departs Central City, thus ending their relationship on good terms.
