Barry Allen / Flash	Grant Gustin	1–present	–	–
Grant Gustin Bartholomew Henry "Barry" Allen is a socially awkward Assistant Crime Scene Investigator for the Central City Police Department that also moonlights as the superhero Flash. In season one, Barry was a traumatized child (portrayed by Logan Williams) when his mother (Nora Allen) was murdered by the Reverse-Flash, with his father, Henry Allen, being framed for the crime. Barry was subsequently adopted by Joe West and spent his whole life trying to discover what really happened that night. Moments after an explosion at the S.T.A.R. Labs particle accelerator, Barry is struck by lightning in his laboratory and doused by chemicals affected by the accident. When he recovers from a nine-month coma he has superhuman speed. He uses his new powers to fight crimes and hunt other metahumans, other humans with powers, in Central City as the masked superhero known as the Flash, while trying to unravel the mystery of his mother's murderer's identity for his father's sake. Barry has long harbored feelings for Iris West since childhood and kept them to himself. He eventually reveals his feelings, leading to complications regarding Iris' relationship with Eddie; however, he learns from a 2024 newspaper in the Time Vault at S.T.A.R. Labs that he may eventually marry Iris. He also shares a close father-son bond with Joe and often asks for advice regarding his feelings for Iris and also what course of action to take as a hero. Initially however, Barry resented Joe's refusing to believe in the circumstances of Nora's murder and Henry's innocence. As a result of this, Barry was hesitant to accept Joe as his surrogate father. Although Joe had come to have this view toward Barry years before. Barry also becomes good friends with Cisco, Caitlin and his idol Dr. Wells who acts as his mentor while on missions. Dr. Wells gave Barry advice on how to adapt and increase his range of powers. However, he later becomes suspicious of Dr. Wells, and eventually learns his mentor is actually Eobard Thawne / Reverse-Flash in disguise, leading him to develop a deep resentment toward the imposter. At last, Barry discovers Eobard's plot to use the Flash's speed and the particle accelerator to generate a portal to his own time, while at the same time Barry can travel back to the night of his mother's murder and prevent it. Barry agrees but is warned by his older counterpart not to interfere and instead chooses to fight the Reverse-Flash and stop him from returning to the future. He is almost killed during the fight until Eddie sacrifices himself to erase Eobard from existence which causes a wormhole to emerge that Ronnie also stops but at the cost of his own life. In season two, Barry becomes reclusive following the deaths of Eddie and Ronnie, but a near-death experience convinces him to work with his friends again. He also discovers a recording left containing Eobard's confession to Nora's murder which allows Henry's freedom. Barry later becomes the target of various metahumans working for the enigmatic speedster Zoom and is confronted by Jay Garrick, a speedster from Earth-2 who also operated as the Flash and informs him that Zoom seeks to kill Barry in order to be the only speedster in the multiverse. He also struggles with his choice not to save his mother and struggles to move on, from her death and his hatred towards Eobard, and is left uneasy when Eobard claims on his confession recording that Barry will never be happy which Barry believes may be true as Eobard knew his future self. Eventually Barry realizes that hating Eobard won't let him move on with his life and chooses to forgive his nemesis, and opts to prove him wrong by finding happiness. Having moved on from Iris on good terms, Barry sparks up romance with partner Detective Patty Spivot; they later decide to separate after Patty learns of Barry's secret identity before leaving Central City, as they think that doing so will keep her safe. Barry also grudgingly works with Dr. Harrison "Harry" Wells of Earth-2 due to his role in creating Zoom, and eventually accepts him as an ally after Barry learns that Zoom kidnaps Harry's daughter. Barry later encounters a younger Eobard, who has yet to murder his mother, but also learns that any attempts to alter events he has caused will alter the timeline too significantly and is forced to let him go, accepting he will keep facing Eobard again until he catches up to his older self. After befriending Harry's daughter and escaping Earth-2 with her, Harry, and Cisco, Barry is grief-stricken following Jay's apparent murder by Zoom. However, Barry and the team later discover that Zoom is Jay himself and subsequently learn of his true identity, Hunter Zolomon, needing Barry's speed to cure himself of a terminal illness caused by his usage of the Velocity drugs. In order to get himself faster to stop Hunter, Barry travels back in time, so that he can ask Eobard — who disguises as Harrison Wells then — for help, feeling that his long-time archenemy will be willing to do so; in the process, Barry slightly alters time resulting in Hartley Rathaway's reformation and becoming his ally. After sacrificing his powers to save Joe's son Wally from Zoom, Harry offers to help Barry recreate the events that gave him his speed, but he disappears as the particle accelerator explodes. Finding himself trapped in the Speed Force, its sentience reveals its origins to Barry and works to help him move on from his mother's death before he returns home. After saving the city from Hunter's army, despite having finally accepted his mother's death, Barry suffers yet another tragedy after Hunter kills his father at his childhood home where his mother was killed. Barry then avenges his father by luring the Time Wraiths to his enemy, transforming Zoom into a corpse-like creature before they drag him into the time stream. Barry is further grief-stricken for his father when he discovers that Hunter's masked prisoner, the real Jay Garrick, is also the Earth-3 counterpart of Henry. Barry, unwilling to suffer the loss of another parent, travels back to the past and saves his mother from Eobard, altering his past in hopes that his parents would live. The Earth-2 version of the character (also portrayed by Gustin) is a non-metahuman who works as a CSI at Central City Police Department in addition to a PhD graduate. He is married to Iris but is despised by Joe. He is insecure and more awkward than his Earth-1 counterpart, but after learning that his counterpart is a hero, he is inspirited to try to help those in need; he helped rescue his doppelgänger and Harrison Wells' daughter from Zoom. In season three, Barry saves his mother from Reverse Flash, but then he opens a new timeline which makes him no longer the Flash. In the new timeline, Barry is just an ordinary person working for CSI without any connection to Iris' family and the new timeline's memory is overwriting Barry's memory while he is using his speed force. Ultimately he has to release Eobard to restore the timeline. However, something has been changed even after he restores the timeline, namely, Iris and Joe's not talking to each other for years and may even rewritten his own destiny with Iris. This provokes Barry to time travel again to make things right, only to be intercepted by Earth-3's Flash (Jay Garrick) who advise him to live with his mistake from creating the 'Flashpoint' timeline. Barry is troubled when Wally has dreams of being a speedster 'Kid Flash'. This is the hero Wally was in Flashpoint.

Caitlin Snow / Killer Frost	Danielle Panabaker	1–present	–	-
Danielle Panabaker Dr. Caitlin Snow is a bioengineer who works at S.T.A.R. Labs. In season one, she provides the medical support for Barry's team. Caitlin is initially the most temperamental and uptight person on the team, mainly out of grief for her fiancé Ronnie Raymond, believing Ronnie was killed in S.T.A.R. Labs' particle accelerator explosion. However, she later discovers that her fiancé survived and is ultimately the metahuman Firestorm. Subsequently after embracing the loss of Ronnie, before learning that the latter is alive, she becomes much more compassionate and kinder. When she discovers that Ronnie is actually Professor Martin Stein, merged with Ronnie's body and Ronnie's mind locked away, Caitlin convinces Stein to let her team help. Eventually, she succeeds in separating Ronnie and Stein but, after an encounter with General Wade Eiling, Ronnie and Stein are forced to leave to keep her safe but Caitlin is understanding and hopes that they will be reunited again one day. When Dr. Wells is implicated to be the Reverse-Flash, Caitlin is the most skeptical but is convinced when Cisco and Joe find the real Dr. Wells' corpse and discover their mentor's true identity. In the finale when Ronnie returns to help Barry and Oliver Queen against Reverse-Flash, Caitlin and Ronnie marry. In season two, Caitlin is widowed following Ronnie's sacrifice in saving the Flash and Central City from the singularity. She initially works at Mercury Labs but eventually goes back to S.T.A.R. Labs to aid in Barry's fight against Zoom, a speedster from the parallel Earth-2. Unlike when most of the team encounters Dr. Harrison "Harry" Wells of Earth-2, Caitlin isn't skeptical to trust Harry. Caitlin also develops romance with Jay Garrick, the Earth-2 Flash and Zoom's archenemy, but discovers that Jay is dying due to Zoom stealing his speed and attempts to help. Caitlin and Harry later develop a speed drug called "Velocity-6" which grants temporary speed but causes cellular degeneration. When Barry is on Earth-2 and the city is endangered by Geomancer, Caitlin is able to perfect it to Velocity-9 to grant Jay's speed back and repair his damaged cells. Following Jay's apparent murder by Zoom, she tries to cope by hiding her emotions, which some fear could lead her to be like her Earth-2 counterpart, Killer Frost. Caitlin is devastated and hateful toward Jay when the team discovers that Jay faked his death and is actually Zoom himself, whose real name is Hunter Zolomon, a serial killer on Earth-2. Hunter forces Barry to give up his speed and abducts Caitlin, having genuinely fallen in love with her, and brings her to Earth-2. After meeting her doppelgänger and almost being murdered by her, Zoom takes Caitlin back to Earth-1 so she can watch as he conquers it just like he did Earth-2. Hunter tries to manipulate her into turning evil like Killer Frost, believing Caitlin has a darkness inside her. Despite Zoom's ultimatum, Caitlin returns to S.T.A.R Labs unharmed to aid the Team Flash during the metapocolypse. However Caitlin has become emotionally unstable and suffers acute stress disorder seeing visions of Zoom and struggles to hold her grip on reality. The Earth-2 version of the character (also portrayed by Panabaker) is the metahuman villainess Killer Frost, who is married to Deathstorm (Ronnie Raymond of Earth-2) and is later grief-stricken following his murder by Zoom. The two work for Zoom along with Reverb. Unlike her Earth-1 self, Caitlin did not finish medical school and becomes a criminal afterward, and she had a brother named Charlie until his death. After she and Ronnie are exposed to the particle accelerator explosion on her Earth, Caitlin develops the powers of cryokinesis and becomes Killer Frost while Ronnie merges with Martin Stein and becomes a pyrokinetic entity like his doppelgänger. Caitlin's cryokinesis also caused her skin to turn pale, her hair white and her lips and eyes blue, rendering her unable to so much as touch anyone without exposing them to absolute sub-zero temperatures and killing them. The only person immune to this is Ronnie due to having almost supernova level pyrokinetic heat. Initially betraying Zoom's Earth-1 enemies, Caitlin decently helps them escape from Earth-2. Though Zoom initially spares Caitlin's life as the result of his affection for her Earth-1 counterpart, he eventually kills her when she tries to murder her doppelgänger out of revenge upon Zoom for killing Ronnie. In season three, she is a pediatric ophthalmologist in the Flashpoint timeline. In the resets timeline with some changed events, Caitlin is revealed to have developed cryokinetic abilities. However she has very little control over it and her physical appearance has begun to resemble that of her Earth-2 doppelgänger with her lips turning blue and her hair turning white. While highly distressed at this, Caitlin steals power cuffs of Cisco which dampen her power. When she reveals to Cisco that she stole them, he asks her why she needed them. Cisco vibes Caitlin as Killer Frost and reveals her secret to the team. When Barry comes under attack from Savitar she uses her powers to rescue the former, but this has worsen her condition and her friends are struggling to help her.

He briefly appears in a vision as a result of Barry's guiltiness 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, and Barry offers to make Eddie a video message to Iris so that Iris can let Eddie go and move on from him peacefully. Cosnett was originally slated to portray Jay Garrick in the pilot before the character was changed to Eddie Thawne. First appearance: "Pilot"
Cisco Ramon / Vibe	Carlos Valdes	1–present	–	–
Carlos Valdes Francisco "Cisco" Ramon is a mechanical engineering genius who works at S.T.A.R. Labs. He is also a metahuman superhero codenamed Vibe. In season one, Cisco is the youngest member of the team of scientists at S.T.A.R. Labs who has a very relaxed and comedic wit. Cisco also has a tendency to nickname the metahuman villains they face, some of whom actually do adopt these names for themselves, and develops equipment and arsenal for Barry Allen and his vigilante allies. He especially forms a friendly bond with Ray Palmer (the Atom) because of their genius intellects and shared tendency to nickname enemies, and is an admirer of Dinah Laurel Lance (Black Canary). Cisco is on bad terms with his brother Dante Ramon, the family's favorite despite the most emotionally insecure. Despite his close friendship with Barry, Cisco is also 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 eventually stolen by criminals Leonard Snart and Mick Rory as means for them to against the Flash. Although he is considered a surrogate son of "Harrison Wells"/Eobard Thawne, he is initially the first person to discover Wells' true identity for which he is killed until Barry resets the timeline; yet Cisco retains the memories of the events that led to his murder. Cisco learns from Eobard that this is because he was also affected by the particle accelerator's explosion and thus is now a metahuman, having the ability to see into alternate timelines and realities and other powers, but is afraid of what may happen because of them. In season two, Cisco is hired by Central City Police Department as its technical advisor and metahuman task force's armorer, building various means for the police to counter super-criminals. He frequently works with Joe West in combating them. Cisco also develops metahuman abilities that allow him to see visions (or vibes). He uses this ability to locate Earth-2 metahumans through touching something of their possession; he is not yet in full control of his new powers. Martin Stein is the first to discover his secret and later Cisco is forced to reveal his powers to the rest of the team, because of Harry Wells of Earth-2. Cisco adopts the codename "Vibe", and receives a retrofitting visor from S.T.A.R. Labs that can help him control his powers. He initially struggles to trust Harry due to his experience with Eobard, but after discovering Harry needs help rescuing his own daughter, realizes Harry is not like Eobard. Despite it, he still cannot get along with Harry due to contrasting personalities, even admitting that Eobard was a nicer guy. However, both Cisco and Harry are film enthusiasts and they occasionally quote their favorite movies when having conversations. He dates a local barista, Kendra Saunders, until separating following the discovery of Kendra's heroic destiny as Hawkgirl. After encountering his corrupt Earth-2 doppelgänger, Reverb, Cisco fears that he is on the path to becoming as villainous as his counterpart. However, because of the escalating threats from Zoom, Cisco tries 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 villainous Earth-2 doppelgänger, Black Siren, Cisco briefly displays a powerful sonic attack against her, but with little control over it. Cisco also develops the ability to open portals to parallel universes that he is familiar with. The Earth-2 version of the character (also portrayed by Valdes) is the metahuman villain Reverb, who works for Zoom along with Killer Frost and Deathstorm before he — along with Deathstorm — is killed by Zoom. Cisco has more experience and control of his powers than his Earth-1 self, which has been proven when he has even been aware of Vibe's existence and powers before the latter appears on Earth-2; in addition to having the same sensory ability, he can manipulate sonic vibrations to create powerful shock waves of considerable strength, thus implying Vibe's own progressing abilities. It is implied that Cisco's power level surpasses both Killer Frost and Deathstorm, as they are intimidated by him. His visor technology is obtained by his Earth-1 counterpart following his death, and Harry later uses its components to modify Vibe's own visor. In Season 3, Cisco is getting to grips with his brother's death (which is a result of Flashpoint), but his grief is worsen when Cisco learned that Barry is inadvertently responsible for Dante's death; their friendship was strained for a while. But he and Barry make up when he changes time during the Dominators Invasion. He is starting to use his powers better and gains a new precognitive ability . He is based on the DC Comics character of the same name. First appearances: "Pilot" (Earth-1) "Welcome to Earth-2" (Earth-2)
Harrison Wells	Tom Cavanagh	1–present	–	-
Tom Cavanagh Dr. Harrison Wells is the mind and money behind the S.T.A.R. Labs Particle Accelerator in Central City. In season one, he activates a particle accelerator that malfunctions, releasing dark matter energy that kills several people and grants various individuals metahuman abilities, including Barry Allen. Six months later, Wells is a recluse and a pariah, confined to a wheelchair. Along with Cisco Ramon and Caitlin Snow, he helps develop Barry's powers as the Flash and mentors the youth in pushing speed to the limit to come up with novel solutions to take down metahuman criminals. However, Wells is revealed to have many secrets: he is faking paralysis, possesses the computer Gideon with futuristic information, and is willing to kill to protect his protégé and cover his own tracks. He turns to be the Reverse-Flash, a mysterious tachyon-powered speedster that occasionally terrorizing the Flash and the S.T.A.R. Labs team despite being close to all of them, especially Barry and Cisco. Despite being a father figure alongside Joe West and Henry Allen to Barry, Wells is eventually revealed to be Eobard Thawne, the Flash's archenemy from the future and Eddie Thawne's descendent. He transmuted the appearance of the real Harrison Wells, killing the scientist and his wife Tess Morgan (Harrison's partner in scientific research) whilst doing so; the investigation into Tess' death by Joe and Cisco leads to the discovery of Harrison's corpse and Eobard's façade. Although his tachyon equipment restored most of his former abilities, Eobard orchestrated the events that would turn Barry into the Flash himself in order to use Barry's connection to the Speed Force to create a wormhole and return to his own time period. However, the Flash foils the Reverse-Flash's plan to return to the future, resulting in the two speedsters engaging each other again. As the Reverse-Flash attempts to kill the Flash, Eddie sacrifices himself, which causes Eobard to cease to exist. Eobard has sporadic appearances as Wells in season two. He had a will that left S.T.A.R. Labs to Barry along with a recorded confession that would clear Henry of all charges in the event of his death. Barry later has a time travel trip to ask him to help him get faster; Eobard refuses at first, but agrees to help after Barry convinces him that his plan is successful in the future. Season two features the Earth-2 version of Harrison "Harry" Wells, the father of Jesse Wells. Like Eobard, he was responsible for the creation of metahumans on Earth-2 using a particle accelerator which also exploded, including the psychopathic serial killer Hunter Zolomon as the rogue speedster Zoom. However, he refused to take responsibility for the metahumans, while making a profit with developing metahuman detector technology. But when Zoom kidnaps Jesse, Harry travels to Earth-1 to assist Barry in the fight against Zoom's extorted metahumans and 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 doppleganger's name and legacy. Harry also 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. 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 so Barry and Cisco decide to travel to Earth-2 with Harry to rescue Jesse. After their mission is complete, Harry and Jesse seek refuge on Earth-1 from Zoom's pursuit. After Barry's speed is sacrificed to Zoom to save Wally West, Harry recreates a miniature particle accelerator to help Barry regain these powers based on Eobard's plans. 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; he is able to bring Barry back with Cisco and Iris West's help, and Barry wakes Jesse from the coma. After Zoom's defeat, Harry and Jesse return home 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 tries to have the team talk his daughter out of pursuing heroics. After Barry and Jesse are forced to team up, Harry becomes more supporting of it. Harry and Jesse return to Earth-2 a few days later so Jesse can protect Earth-2 Central City but before leaving Harry helps the team locate his alternate counterpart from Earth-19 to substitute in his absence. Season three introduces the Earth-19 version of Harrison "H.R." Wells. H.R. is one of 16 other versions of the man that cracks the cryptogram sent by Harry through the Multiverse and expresses interest in aiding Team Flash, and is brought to Earth-1 by Cisco to substitute for Harry's absence. Additionally other versions of Wells, including one from Earth-17, are also featured. When dealing with the criminal corperating with H.R., Cisco figures out that H.R. is not a scientist even though he works at S.T.A.R. Labs in Earth-19 too. Barry suggests letting H.R. stay for a few more weeks see if they could still work together or otherwise they will send him back to Earth-19. In each episode, H.R. proves his worth despite not being a scientist, that he is generally intelligent and intuitive, helps forming plans and locating super-criminals. He also agrees to train Wally to be a hero after seeing the youth's potentials as a speedster. Harrison Wells is an original character created for the series while Eobard Thawne is based on the DC Comics character of the same name. First appearances: "Pilot" (Eobard Thawne) "Tricksters" (Earth-1) "Flash of Two Worlds" (Earth-2) "The New Rogues" (Earth-17, Earth-19, and two unnamed Earths)

Jesse L. Martin Joseph "Joe" West is a police detective, father of Iris and Wally West, and a foster father to Barry Allen following Nora Allen's death and Henry Allen's incarceration. Introduced in season one, he is one of the few who knows Barry's secrets; he becomes his reluctant partner against metahuman criminals, and offers Barry supports in both crimefighting and life issues, mainly revolving Barry's feelings for Iris which he has been aware of since they were children. He also helps Barry in the attempts to prove Henry's innocence. Suspicious of Harrison Wells' intentions, Joe secretly investigates Wells and he and the team ultimately discover Wells' true identity. In season two, Joe is in charge of the department's new metahuman taskforce, in which no one except Cisco and Patty Spivot yet joined due to the officers' fears of the metahumans, leading him to rely on Cisco's inventions when dealing with super criminals and becomes Patty's mentor in police work. He also gradually becomes a father figure to Cisco and Patty. In addition, Joe struggles with the relationship with his estranged wife, Francine. Unbeknownst to Joe, he also fathered a son, Wally, with Francine prior to her leaving her family. He learns of his wife's attempt at entrusting their son to him and Iris before she dies a few weeks after Iris finds out. Distraught after learning Wally's existence, Joe nonetheless seeks to build a relationship with him, and finally meets Wally after his son arrives to spend Christmas time with him and Iris. Though both Joe and Iris see Wally as a rebellious and reckless youth because of his past as a drag racer, and Joe later acknowledging that he was like Wally during his youth, they also see that Wally is a decent person taking care of his terminally-ill mother. Initially, Joe is not sure of how to be a father to Wally, but he gradually learns how to treat him the same way as he treats Iris and Barry, and becomes proud of Wally's aptitude in mechanical engineering and ultimately discovers his love for his son after Zoom kidnaps Wally and become close to him since. Although Joe is proud that Wally feels a need to help people in needs, he forbids his son from dropping out of college to follow his footsteps as a police officer as he did Iris, preferring that his children being safe and happy rather than dealing with the dangers and burdens associated with law enforcement. After Wally is exposed to the dark matter with Jesse Wells during the attempt to restore Barry's powers, Joe suspects that his son is turning into a metahuman due to his own knowledge on the particle accelerator explosion. The Earth-2 version of the character, Joseph West (also portrayed by Martin), is a musician who, unlike his Earth-1 counterpart, does not share the same father-son bond with Barry and actually blames Barry for Iris's becoming a police officer.

Wally West / Kid Flash	Keiynan Lonsdale	2–present	–	–
Keiynan Lonsdale Wallace "Wally" West is the unknown son of Joe and Iris's brother, described as "a bit of a wayward kid who has some attitude problems and some authority issues and is quick with a sassy remark". Wally was born after his mother's abandonment of her family (who later finds herself pregnant), leading Joe and Iris unaware of his existence for eighteen years until the latter finds out. Wally finally meets his father and sister during a Christmas party shortly before his mother dies; he has since struggled to bond with Joe and Iris. He also forms a brotherly bond with Barry Allen, who is fostered by Joe (despite his jealousy due to this fact), although he is suspicious of Barry's weird behavior as well. Formerly a drag racer, Wally is now enrolled in the same university Iris was in, majoring in mechanical engineering. After repeatedly being rescued by the Flash, Wally becomes fascinated with the superhero and eventually discovers that his father has a connection with him, but is unaware that he is Barry due to Wally's respect for his father's wishes to keep the Flash's secrets. He is also inspired by both his father and the Flash to help people, resulting in him ultimately becoming close to the former. Later, when Wally and Jesse Wells are locked in the Time Vault at S.T.A.R. Labs by their fathers for protection against Zoom, they work together to escape but are accidentally affected by the dark matter released from Jesse's father's attempt to restore Barry's powers; his father and later Barry, suspect that Wally is turning into a metahuman after the incident. Eventually, Wally discovers Barry's secrets when Zoom abducts and kills the latter's father, and fully accepts Barry after he rescues Wally's father from Zoom. 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 disliked second seasons of television series that would introduce cousins of characters that were never previously mentioned, feeling it was "weird". Keiynan Lonsdale originally auditioned for Legends of Tomorrow to portray Jefferson "Jax" Jackson. Though an alternate timeline version of Wally became the Flash in the third season premiere, it remains to be seen whether Wally will exhibit the same powers as his counterpart. In the post-Flashpoint timeline, Wally struggles to become a speedster after witnessing Jesse became one. After Alchemy seeking Wally out, the latter learns of his alternate life, and uses the villain's device to gain his speed against his father and Barry's wishes. Wally then becomes a speedster after Caitlin stabilizes his metamorphosis, and he eagers to join Barry as his partner. He is based on the DC Comics character of the same name. First appearance: "Running to Stand Still"

Recurring characters

This is a list of recurring actors and the characters they portrayed in multiple episodes, which were significant roles, sometimes across multiple seasons. The characters are listed, in alphabetical order by actor, by the season in which they first appeared.

Season One

• Robbie Amell portrays Ronnie Raymond / Firestorm, an engineer at S.T.A.R. Labs and Caitlin Snow’s fiancé, based on the DC Comics character of the same name who is half of the character Firestorm. He is thought to be dead in the particle accelerator explosion, saving the lives of his co-workers, including Cisco Ramon. It is later revealed that he survived the accident, which merged him with Martin Stein and the F.I.R.E.S.T.O.R.M. transmutation matrix, transforming both of them into one pyrokinetic entity. Though Firestorm is Ronnie's body, it is Stein who remains in control for most of their existence, yet Ronnie occasionally takes control for brief moments. They eventually learn to control their shared powers, including an ability to separate themselves at will. Like Caitlin, Cisco and Stein, Ronnie also becomes good friends with Barry Allen; he and Barry ultimately join forces with Oliver Queen to subdue the Reverse-Flash. Though Ronnie eventually marries Caitlin, he disappears and is presumed dead when he sacrifices himself to stop the singularity above Central City, giving a final goodbye to Caitlin.
  • Amell also portrays the Earth-2 version of the character, Ronnie Raymond / Deathstorm, who is Killer Frost's husband. He works for Zoom alongside Killer Frost and Reverb. Along with Reverb, Ronnie is killed by Zoom for harming the Flash.
• Stephen Amell portrays Oliver Queen / Green Arrow, a former billionaire playboy who operates as a vigilante in Star City and is a friend of Barry's. Amell stars as the character on Arrow.
  • In opposition to what happened on Earth-1, it is revealed that the Earth-2 version of the Arrow is Robert Queen and Oliver died instead.
• Clancy Brown portrays General Wade Eiling, a U.S. military general with an interest in metahumans, who wants to use them for the army, and has a history with S.T.A.R. Labs. When Eiling is revealed to have learned of Barry Allen's identity as the Flash, Eobard Thawne gives the general to Grodd to be placed under the gorilla's control. After being freed by the Flash, he and Barry form a grudging respect despite their enmity.
• Victor Garber portrays Professor Martin Stein / Firestorm, a nuclear physicist focused on transmutation, based on the DC Comics character of the same name and is also half of the character Firestorm. During their initial merging, Stein remains in control of Firestorm, though Ronnie Raymond occasionally takes control for brief moments. They eventually learn to control their shared powers, including an ability to separate themselves at will. Professor Stein also subsequently gives Barry Allen and Eddie Thawne some insight on the possibility of time travel and their respective destinies. Stein also discovers Cisco Ramon's secret as a metahuman and encourages him to accept the status. After Ronnie's presumed death, Stein becomes a member of Team Flash and the group's scientific advisor following Eobard Thawne's demise. However, when it turns out that his body is unstable as a consequence of the combination of the dark matter with Stein's own matrix, his fusion with Ronnie stabilizing him, Stein gains a new partner in Jefferson "Jax" Jackson. In season 3, Stein discovers that due to both Barry's and his own respective time-traveling actions, he now has a daughter with his wife in the post-Flashpoint timeline; he never had a child prior to the timeline's reset.
  • The Earth-2 version of the character is also one half of the conjoined metahuman criminal Deathstorm. However, Ronnie doesn't release Stein or even listen to him and he eventually stops talking altogether. He is unwillingly killed by Zoom.
• Michelle Harrison portrays Nora Allen, Barry Allen's mother. Although the Reverse-Flash was actually trying to kill the young Barry during the fight with the Flash's future self, Nora was instead Reverse-Flash's target after Flash took the younger Barry to safety, figuring that such a tragedy would prevent Barry from becoming Flash.
  • Harrison also voices the Earth-2 version of the character. On this Earth, she remains happily married to Henry Allen.
• Roger Howarth portrays Mason Bridge, a reporter at the Central City Picture News who mentors Iris West and who has become suspicious of Eobard Thawne and has even found evidence of Simon Stagg's murder when everyone believes Stagg is a recluse. Eventually, Mason is killed by the Reverse-Flash, erasing all evidence to keep secrets. However, Mason's disappearance causes a chain of events that lead Barry Allen and Joe West to discover that the reporter is murdered for getting close to the truth about Thawne. When Iris is worried and begins looking into Mason's disappearance, Eddie Thawne covers with the story that Mason ran away for a girl, but Iris eventually learns the truth for herself.
• Malese Jow portrays Linda Park, a journalist for the Central City Picture News who befriends Iris West and Barry Allen, and briefly dated Barry. The character was originally portrayed by Olivia Cheng in the series Arrow.
  • Jow also portrays the Earth-2 version of the character, Linda Park / Doctor Light, based on the Kimiyo Hoshi version of the character. Unlike her Earth-1 counterpart, this Linda is a thief who is very easily startled and paranoid and willing to do anything to stay out of Zoom's sights.
• Matt Letscher portrays Professor Eobard Thawne / Reverse-Flash, the time-travelling archenemy of Barry Allen / Flash from the future and a descendant of Eddie Thawne, based on the DC Comics character of the same name. Hailing from the 22nd century, Eobard was obsessed with the Flash, and desired to "become" his idol. Having spent years figuring out how the Flash came to be, he managed to successfully duplicate the reaction and become a speedster - only for Eobard to subsequently discover, through time travel, that he was destined to become his idol's greatest enemy, that he would never become his hero, and grew to despise him. Hell-bent on proving himself superior, Eobard would become the "reverse" of everything the Flash was, making it his life's mission to "take" as much as he can from the man he once looked up to, as the Reverse-Flash. Enemies, rivals and opposites for the many years since their initial encounter, neither one of the two speedsters was strong enough to defeat the other. After finally discovering his nemesis' identity, Eobard murdered Nora Allen after a failed attempt to kill Barry as a child, but in the process, lost his connection to the Speed Force and became stranded in the past. He transmutes the likeness of Dr. Harrison Wells as his own appearance, and serves as season one's main antagonist, orchestrating and manipulating various events in hopes of returning to his time period, until Eddie sacrifices himself in the first season finale, causing Eobard's existence to cease. Eobard's first chronological appearance occurs in season two; the Reverse-Flash travels back in time, encountering the Flash for the first time (in Eobard's point of view). In the midst of using Tina McGee's "speed machine" construction to return to his time period via tachyons, he suffers a severe beating at the Flash's hands. While being briefly imprisoned at S.T.A.R. Labs, he came to know about some of his own future actions after interactions with Cisco Ramon and Harry Wells. Eobard is sent bent back home in order to prevent a time paradox, but not before vowing to return and learn the Flash's name. In the second season finale, the Flash travels back to prevent the Reverse-Flash from murdering Nora, effectively altering future events related to Eobard's actions. In season three's premiere, Eobard is imprisoned by Barry while both are in the Flashpoint timeline, and tries to convince his foe to let him kill Nora so he can restore the reality they both know, which Barry is initially against. But when Barry starts to lose memories and realizes this new timeline's dangers, Eobard is reluctantly released. The Reverse-Flash then travels back and murders Nora which supposedly "fixes" the timeline. Eobard then brings Barry back to the different timeline and leaves, but not before taunting his nemesis.
• Peyton List portrays Lisa Snart / Golden Glider, an aspiring criminal and Leonard Snart's younger sister. She shares a mutual attraction with Cisco Ramon who she initially kidnapped for her brother and coerced into creating a gun that turns things into gold, but becomes genuinely fond of later on. Although she helped her brother free the metahuman criminals in the Pipeline, Lisa sought Team Flash's help when her brother was found to be working for their abusive father Lewis Snart (later revealed to be due to her father threatening her life).
• Liam McIntyre portrays Mark Mardon / Weather Wizard, a criminal with the ability to control the weather of his surroundings. Having similar powers to his sibling, Mark returns to Central City seeking revenge on Joe West for killing his brother. He was being held in the S.T.A.R. Labs prison before being set free by Leonard Snart and being offered a place in his crew the "Rogues". Mark is also revealed to have murdered Patty Spivot's father during a bank robbery with his brother months prior to the particle accelerator's explosion. He remains nursing his grudge against both Detective West and the Flash whom he hates for his numerous defeats by the latter.
• Wentworth Miller portrays Leonard Snart / Captain Cold, the son of a police officer who turns to crime and uses a stolen cryonic technology weapon. Snart is a cunning and intelligent bank robber who seeks to eliminate the Flash, seeing as a threat to his world, and steals a gun from S.T.A.R. Labs, created by Cisco Ramon, that is able to freeze objects and people on contact; Cisco originally created the weapon to stop the Flash if something went wrong. Snart teams up with Mick Rory in an attempt to kill The Flash but fails and yet gets The Flash to reveal to the world that he exists. He is also the brother of Lisa Snart. He also learns from Cisco, after threatening to kill Dante Ramon, that Barry Allen is the Flash. He eventually becomes leader of his crew that Barry dubs the "Rogues". Barry later asks Snart to assist him in transporting metahumans out of Central City to Lian Yu. Snart accepts, in exchange for Barry erasing Snart's criminal record. He double-crosses Barry by sabotaging the truck containing Mark Mardon/Weather Wizard, Kyle Nimbus/The Mist, Roy Bivolo/Rainbow Raider, Jake Simmons/Death Bolt and Shawna Baez/Peek-a-Boo. Snart kills Simmons with his cold gun, claiming Simmons owed him money. Mark and Bivolo now owe Leonard, but Shawna and Nimbus escape. Leonard is later extorted into working for Lewis Snart when his own father plants a bomb inside Lisa's head, but after Team Flash successfully removes it, Leonard kills Lewis out of spite and is arrested for his father's murder, which he doesn't try to resist. He is later broken out by Mardon to aid in getting revenge on Barry but declines and yet warns Barry of Mark's plans.
  • The Earth-2 version of the character is the mayor of Central City.
• Amanda Pays portrays Tina McGee, a role she also played on the 1990 television series. A friend of Harrison Wells (Earth-1 version), she is the director of Mercury Labs and the designer of the tachyon device, which allows any object to move at the speed of light, stolen by the Reverse-Flash once during season one and again in season two. It is later revealed that Dr. McGee is aware of Barry's secret for some time but keeps this knowledge to herself.
• Dominic Purcell portrays Mick Rory / Heat Wave, an arsonist and accomplice of Leonard Snart who, in contrast to his partner, uses a heat gun developed by Cisco Ramon capable of burning almost anything.

• David Ramsey portrays John Diggle / Spartan, a member of Oliver Queen's team and best friend to Oliver. Ramsey stars as the character on Arrow.
• Ciara Renée portrays Kendra Saunders / Chay-Ara / Hawkgirl, a young woman who is just beginning to learn that she has been repeatedly reincarnated over the centuries.

• Emily Bett Rickards portrays Felicity Smoak, a friend and love interest of Oliver Queen, and also a one-time love interest of Barry Allen. Rickards stars as the character on Arrow.
• Patrick Sabongui portrays David Singh, the Central City Police Captain, and superior of Barry Allen, Joe West, Eddie Thawne, Patty Spivot and Julian Albert.
  • Sabongui also portrays the Earth-2 version of the character, a criminal.
• John Wesley Shipp portrays Henry Allen, Barry's father. Shipp previously portrayed Barry Allen / Flash in the 1990 television series. Henry was a respectable doctor before he was wrongfully convicted of murdering his wife Nora Allen and incarcerated in Iron Heights Prison after Eobard Thawne / Reverse-Flash framed him. Only his son Barry and later Joe West believe his innocence. Throughout season one, he learns that Barry is the Flash and is proud of his son. Henry serves as Barry's moral conscience in using these powers wisely, thus keeping Barry from being tempted for personal gains, such as altering their damaged past through time travel despite the possibility of bringing Nora back to life. In season two's premiere, Henry is released from prison upon the discovery of Eobard's confession to Nora's murder. However, he tells Barry that he's leaving Central City to seek a reclusive life as he believes that his presence could hold back Barry's duties as the Flash. He returns later to counsel Barry and offer encouragement after his son's disastrous fight with Hunter Zolomon / Zoom before returning to his seclusion. Depowered, Barry visits his father that has been accustomed to solitary and tranquility; Henry then accompanies his son and joins S.T.A.R. Labs to help in Barry's fight to save the world from Zoom. Henry is killed by Hunter when he wants Barry to relive the same tragedy he went through as a child.
  • Despite not appearing, it is implied that the Earth-2 version of the character remains happily married with Nora Allen.
  • Shipp also portrays the Earth-3 version of the character, Jay Garrick / Flash. Zoom held Jay captive in a failed attempt to harness his speed, and was inspired to take up his persona and falsely operate as the Flash of Earth-2, even using Jay's name. To keep him from escaping, Zoom forced Jay to wear a mask that supressed his speed and prevented him from talking. After Zoom's defeat, Barry rescues Jay, who travels with Harry and Jesse Wells back to Earth-2, who promise to help him find a way home. Jay adopts Hunter's Flash helmet as a symbol of hope, taking satisfaction in taking something from Zoom just as Zoom had done to him. Jay reappears in the Season 3 episode "Paradox" as a sympathetic yet stern mentor to Barry, explaining that time travel can have adverse consequences and that Barry must live with his mistakes from creating the "Flashpoint" timeline.

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."

Season Two

• Violett Beane portrays Jesse Chambers Wells / Jesse Quick, based on the DC Comics character of the same name. Jesse is the daughter of Harrison Wells from Earth-2. Jesse is abducted by Zoom to force Harry to obey his demands by threatening her safety. She is later rescued by her father with the help of Barry, Cisco and Earth-2's Barry Allen and Iris West. Jesse and Harry later seek refuge on Earth-1 to escape from Zoom. Jesse is a science prodigy, which her father occasionally acknowledges that she is much smarter than he is. She also claims to have 5 majors in college, one being bio-chemistry, much to the shock of Team Flash. She also develops a crush on Wally West. She later leaves Central City for Opal City after becoming horrified to learn of Harry's actions in ensuring her safety, murdering a man and putting others at risk, but returns after her father is kidnapped by Griffin Grey. Jesse works with the S.T.A.R. Labs team and also provides her own expertise in biology and other fields of science after Caitlin Snow has been taken by Zoom. As Barry disappears by Harry's dark matter attempts to restore the former's speed, Jesse and Wally are affected by it. Barry wakes Jesse from her coma after he returns from the Speed Force. After Zoom's defeat she and her father return to Earth-2. Months later she and Harry return to Earth-1, with Jesse now exhibiting speedster abilities, though Harry tries to discourage Jesse from pursuing her desire to pursue heroics, having been inspired by watching Barry's heroics. After she and Barry stop Magenta together Harry becomes more encouraging of her desires and he then had Cisco to make her a costume similar to Barry's. After training with Barry for several days she and Harry return to Earth-2 to defend the Central City there, essentially Jesse becoming Earth-2's own Flash under the name 'Jesse Quick'. Jesse and Wally also admit their feelings starting a sort of long-distance relationship.
• Teddy Sears portrays Hunter Zolomon / Zoom, based on the DC Comics character of the same name. An individual from Earth-2, he obsessively desired to become the only speedster in the Multiverse as Zoom (voiced by Tony Todd, with Ryan Handley behind the initial portrayal), the main antagonist of the second season. Hunter was a traumatized child (portrayed by Octavian Kaul) that watched 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 he was dying of an illness afflicted from it. Searching for a cure, he traveled throughout the multiverse and captured Jay Garrick. Unsuccessful in stealing Jay's speed to cure himself, Hunter kept the Flash of Earth-3 imprisoned with a speed dampening mask. Inspired to be both the "hero" and the villain, he used Jay's name as the fraudulent Flash of Earth-2 to instill false hope while taking away said hope as Zoom. After discovering Earth-1, he plots to steal Barry Allen's speed for himself. To ensure Barry has enough speed for him to steal, Zoom begins sending various metahumans from Earth-2 to Earth-1 to fight the Flash of Earth-1 to increase his nemesis's speed, while also infiltrating the team as Jay. Zoom also extorts Harry Wells into physically stealing Barry's speed by kidnapping Jesse Wells. He also becomes Caitlin Snow's new love interest, but she remains unaware of his true nature until Zoom kills a time remnant clone of himself in front of Barry and the team. After succeeding in stealing Barry's speed, Zoom brings his army of Earth-2 metahumans to Earth-1 to conquer the planet and construct a device capable of destroying planets. He aims to destroy every other version of Earth in the Multiverse, leaving only Earth-1 in order to ensure he remains the only speedster in the Multiverse. Hunter also seeks to corrupt Caitlin's mind into becoming like that of her Earth-2 double Killer Frost (so they can resume their relationship) and then Barry's by killing Henry in the same spot Eobard killed his mother, convinced that they are similar because of their childhood traumas. However, Barry ultimately bests Hunter in their final fight and foils his plan, summoning two Time Wraiths to abduct him for his crimes against the timeline and transform him into the "Black Flash", a corpse-like creature enslaved to the Speed Force. 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."
  • Sears also briefly portrays the Earth-1 version of the character, a non-metahuman individual.
• Shantel VanSanten portrays Patty Spivot, based on the DC Comics character of the same name. She is Detective Joe West's new protégée and partner and is the only member of the new metahuman task force at CCPD besides Cisco Ramon and a love interest of Barry Allen. Her father was murdered by Mark Mardon during a bank robbery prior to the particle accelerator's explosion, leaving Patty determined to stop metahuman criminals in remembrance of him, and she becomes a detective under Joe. Despite her father's murder, she does not hate metahumans (as the Mardons weren't empowered at the time of her father's death) and she acknowledges the Flash's heroism. However, she believes that having superhuman power brings out the best or the worst in people. It is later revealed that 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 for her loved ones' sakes. She leaves Central City to pursue her studies in the Forensic Science program at Midway City University, which she previously postponed for investigating her father's murder. She also deduces Barry's secret identity and offers to stay if Barry confirms it and the feelings for her. Barry, however, admits nothing, not wanting to stop Patty from pursuing her dream. Patty surreptitiously does get Barry to reveal the Flash persona to her as she departs Central City, thus ending their relationship on good terms.
  • Though not seen, it's revealed that the character's Earth-2 version is a CSI, showing that she did pursue Forensic Science.
• Vanessa A. Williams portrays Francine West, Iris and Wally West's mother and Joe West's estranged wife. Francine abandoned her family four years prior to Joe taking Barry in, out of guilt of endangering Iris when her daughter was a child during her drug abuse. Following Wally's birth, Francine becomes sober from her addiction and a good mother to her son after her failure with her daughter. After being diagnosed with MacGregor's syndrome (a terminal illness resulted by her past substance abuses), she tries to reconcile with her family and to entrust Wally to them before she dies. Ultimately, Joe and Iris forgive Francine on her deathbed, and accept Wally as part of the family.

Season Three

• Tom Felton portrays Julian Albert / Doctor Alchemy, a fellow crime-scene investigator at the Central City Police Department who is suspicious of Barry Allen.
