The Flash is an American television series developed by writer-producers Greg Berlanti, Andrew Kreisberg and Geoff Johns and is based on the DC Comics character, the Flash. The series premiered on The CW television network in the United States on October 7, 2014. The series is a spin-off from Arrow, a show in the same universe. The first season follows police forensic investigator Barry Allen (Grant Gustin), who develops super-speed after he is struck by lightning. In his attempt to learn about his powers and how to use them for good, he is assisted by S.T.A.R. Labs' Dr. Caitlin Snow (Danielle Panabaker), Cisco Ramon (Carlos Valdes) and Dr. Harrison Wells (Tom Cavanagh). Barry tries to solve the murder of his mother (Michelle Harrison) by a superhuman attacker (Matt Letscher). 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.

Main characters

Barry Allen / Flash

Further information: Flash (Barry Allen)

Grant Gustin

Bartholomew Henry "Barry" Allen (portrayed by Grant Gustin) is an awkward assistant crime-scene investigator for the Central City Police Department, who moonlights as the Flash. As a child, Barry (Logan Williams) is traumatized when his mother, Nora, is murdered by the Reverse-Flash. His father, Henry, is framed for the crime. Joe West becomes Barry's legal guardian, and Barry spends his life trying to discover what happened that night. He first appears in the second season of Arrow, personally investigating a superhuman-related crime in Starling City, and learns of Oliver Queen's identity as the Arrow. They become good friends. Sometime after Barry returns to Central City, he is struck in his laboratory by lightning that 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 the masked superhero, Flash, while he tries to identify his mother's murderer. Although Barry has loved Iris West since childhood, he has kept his feelings to himself. He reveals his feelings, complicating Iris' relationship with Eddie. 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, Caitlin and Dr. Wells, his idol and mentor on missions. Although Dr. Wells advises Barry about how to adapt and increase his powers, Barry becomes suspicious and learns that he is Eobard Thawne (Reverse-Flash) in disguise. After Eobard is unmasked, he tells Barry about his plan to use the Flash's speed and the particle accelerator to generate a portal to his own time (allowing Barry to return to the night of his mother's murder and prevent it). Barry travels back in time, but is warned by his older self not to interfere. He returns to the present and fights with Eobard, stopping him from returning to the future. Although Barry is almost killed, Eddie sacrifices himself to destroy Eobard. This creates a miniature black hole, which Ronnie stops with his own life.

In season two, Barry becomes reclusive after Eddie and Ronnie's deaths, until a near-death experience convinces him to work with his friends again. He discovers a recording of Eobard's confession to Nora's murder that clear his father of all charges, with Barry inheriting Harrison Wells' fortune and resources from Eobard. Though rich, Barry chooses to remain 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 the Earth-2's Dr. Harrison "Harry" Wells. Barry struggles with his choice to not save his mother and his hatred of Eobard, gradually accepting Harry as a friend upon learning that he trying to save his daughter Jesse. The group are aided by Earth-2's Flash Jay Garrick before they learn that he is actually a time remnant clone of Hunter Zolomon, who is Zoom, and he steals Barry's Speed Force to cure his terminal illness. After sacrificing his powers to save Wally 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 his mother's death. After returning and defeating Zoom's army, Barry is forced to watch his father's death in his childhood home. He avenges his father by luring the Time Wraiths to Zoom, who is 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 his mother's death without considering the consequences.

In season three, Barry saves his mother from Reverse-Flash and creates a new timeline (called "Flashpoint" by Eobard) in which he is no longer the Flash. In the new timeline, Barry is a CSI without any connection to Iris' family. Barry's memories of the new timeline overwrites his memories of the original timeline, forcing Barry to release Eobard in order to restore the timeline. Barry learns his actions made vast differences to the restored timeline and goes back in time again in an attempt to 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 and trains him, Barry struggles with the temptation to use his powers for personal gain. His struggles worsen upon learning the identity of Savitar, a clone of a future version of himself. After the rogue time remnant is killed, Barry takes Savitar's place in the Speed Force prison to atone for causing the events of third season to occur. He appoints Wally as the new Flash before taking his leave.

Gustin also portrays Savitar (voiced by Tobin Bell in his exosuit and Andre Tricoteux behind the initial portrayal), who is a temporal duplicate of a future version Barry as a bootstrap paradox against Savitar's future self. 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 Savitar is a clone of Barry's possible future self, he is essentially what Barry would become if he gave into his dark impulses. Following his imprisonment in the Speed Force after a battle with the Flash in 2021, Savitar takes advantage of Barry's post-Flashpoint paradox to regain his freedom and cement his existence by killing Iris West so that Barry would be in the right state of mind to ensure his creation. After H.R. Wells 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.

Gustin also plays the Earth-2 non-metahuman Barry, a CSI at the Central City Police Department and a Ph.D. graduate who is married to Iris, and a version of the Flash from an alternate 2024 who was broken from his battles against Savitar and told his younger self of physicist Doctor Tracy Brand.

Iris West

Further information: Iris West

Candice Patton

Iris West (portrayed by Candice Patton), daughter of detective Joe West, is the girlfriend of Barry Allen and based on the DC Comics character of the same name.

In season one, Iris is a barista for a local espresso while she studies journalism. After graduating, she becomes an investigative reporter for the Central City Picture News. Iris, fascinated by the Flash, wants to learn more about him. She begins dating her father's partner, Eddie Thawne, while Barry is in a coma. When Barry admits his feelings about her, she is conflicted. Iris learns that Barry is the Flash after he saves her from Reverse-Flash. She feels betrayed by Barry for keeping secrets and further upset at her father for conspiring with him. Iris chooses Eddie, and she and Barry decide to let things proceed between them naturally.

In season two, Iris becomes more involved with the S.T.A.R. Labs team. She encourages Barry to pursue a relationship with Patty Spivot. Iris learns that her mother is terminally ill and gave birth to a son, Wally, after abandoning her family. She tells her father about Wally, and they meet him when he arrives at Christmas. Iris forgives her mother on her deathbed and bonds with Wally after she saves his life. 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.

Season three, in the Flashpoint timeline, Iris assists Wally in fighting crime as the Flash. 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. 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.

Patton also portrays the Earth-2 Iris, a detective for the Central City Police Department who is married to Barry. Mourning her father, Iris is comforted after she helps Team Flash deal with Zoom.

Caitlin Snow / Killer Frost

Further information: Killer Frost

Danielle Panabaker

Dr. Caitlin "Cait" Snow (portrayed by Danielle Panabaker) is a bioengineer who works at S.T.A.R. Labs. She is based on the DC Comics character of the same name.

In season one, she provides the medical support for Barry's team. Caitlin is the most uptight person on the team, still grieving for her fiancé Ronnie Raymond, whom she lost in the particle accelerator explosion. After embracing her loss, she becomes more compassionate and kinder. She discovers that Ronnie survived and is the metahuman Firestorm, merged with Professor Martin Stein. Caitlin convinces Stein to let her team help separate the two, which is successful. Ronnie leaves with Stein after an encounter with General Wade Eiling, and Caitlin hopes they will be reunited one day. When Dr. Wells is exposed as the Reverse-Flash, Caitlin is initially skeptical but is convinced when Cisco and Joe find the real Dr. Wells' corpse and discover their mentor's true identity. 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 to stop the singularity. She works at Mercury labs before returning to S.T.A.R. Labs to aid Barry's fight against Zoom. She is not skeptical of Dr. Harrison "Harry" Wells of Earth-2, unlike most of the team. She begins a romantic relationship with Jay Garrick, the Earth-2 Flash. After discovering Jay is dying, Caitlin, along with Harry, develops "Velocity-6" to grant temporary speed. She perfects it to Velocity-9 to get Jay's speed back and repair his damaged cells. She is devastated when the team discovers Jay faked his death and is actually Zoom himself, whose real name is Hunter Zolomon. Hunter abducts Caitlin, having genuinely fallen in love with her, to bring her to Earth-2. After meeting her doppelgänger and almost getting murdered, Zoom takes Caitlin back to Earth-1 so she can watch as he conquers it. 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 Team Flash. Afterward, however, Caitlin 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. 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 turns her skin pale, her hair white and her lips and eyes blue, rendering her unable to 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 helps them escape from Earth-2. Though Zoom initially spares Caitlin's life, he 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 reset timeline, Caitlin is revealed to have developed cryokinetic abilities. She has very little control over them, and her physical appearance becomes more like Earth-2 Killer Frost, with blue lips and white hair. Highly distressed at this, Caitlin uses power cuffs built by Cisco to dampen her power. She later has Cisco vibe her, seeing her future as Killer Frost, and reveals her secret to the team. When Barry is under attack from Savitar she uses her powers to rescue him, but this worsens her condition. Her developing powers have psychological effects, in conjunction with her own struggle to retain her sanity, which cause her to develop a form of dissociative identity disorder. Eventually, Caitlin's dark side completely takes over, and she aligns herself with Savitar after he unmasked himself as a time remnant variant of Barry. Unlike her Earth-2 counterpart, the fully turned Killer Frost has more control over her powers; she is able to touch anyone without killing them. Savitar uses Caitlin's powers against the Black Flash (Hunter Zolomon), and she is able to kill him. However, a chain of events leads to Caitlin regaining control over herself and helping her friends against Savitar. Despite Julian and her mother successfully developing a cure for her condition, Caitlin leaves Central City to find herself. In an alternate 2024, Caitlin is a metahuman villainess like her Earth-2 doppelgänger.

Eddie Thawne

Rick Cosnett

Edward "Eddie" Thawne (portrayed by Rick Cosnett) is a recent transfer to the Central City Police Department from Keystone City.

In season one, Eddie is Joe West's detective partner and Iris West's boyfriend. He is initially jealous of Barry because of his childhood bond with Iris. Eddie is suspicious of Barry's true feelings for Iris despite denials, though Barry and Eddie do eventually become good friends. For a time, Eddie sees the Flash as a menace and is head of a task force dedicated to capturing the hero. He changes his perception of the Flash after a near-death experience with the Reverse-Flash. He learns of Barry's secret identity and helps in the investigation of Harrison Wells as the Reverse-Flash. Eddie later discovers that he is a forefather of Eobard Thawne and that Iris may eventually marry Barry. However, after a conversation with Martin Stein, Eddie realizes that the future is not set and that he is in control of his own destiny. Eddie chooses to stop his sociopathic descendant from killing Barry by killing himself, dying in Iris' arms while causing Eobard to vanish. 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 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 go and move on from him peacefully.

In season three, the Speed Force takes the form of Eddie to help teach Barry to realize the true meaning of sacrifice and that he must be the one to save Iris from Savitar.

Cosnett was originally slated to portray Jay Garrick in the pilot before the character was changed to Eddie Thawne.

Cisco Ramon / Vibe

Further information: Vibe (comics)

Carlos Valdes

Francisco "Cisco" Ramon (portrayed by Carlos Valdes) is a mechanical engineering genius who works at S.T.A.R. Labs. He is also a metahuman superhero codenamed 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, with a tendency to nickname the metahuman villains they face. He develops equipment and arsenal for Barry Allen 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 Ramon. 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 stolen by criminals Leonard Snart and Mick Rory as means for them to fight against the Flash. Although Wells/Thawne considers him a surrogate son, he is killed for being the first person to discover Wells' true identity, until Barry resets the timeline; Cisco retains the memories of his murder and the knowledge of the Reverse-Flash's true identity. Cisco learns from Eobard that this is because he was also affected by the particle accelerator's explosion, having the ability to see into alternate timelines and realities and other powers.

In season two, Cisco is a technical advisor and metahuman task force armorer for the Central City Police Department; he builds various 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 retrofitting 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. Despite it, he still cannot get along with Harry due to contrasting personalities, even admitting that Eobard was a nicer guy. He briefly dates Kendra Saunders. After encountering his Earth-2 doppelgänger, Reverb, Cisco fears that he is on the path to becoming as villainous as him. However, 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 Earth-2 doppelgänger, Black Siren, Cisco briefly displays a powerful sonic attack against her. He also develops the ability to open portals to parallel universes.

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 is killed by Zoom. Cisco 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 Earth-1 Cisco appears on Earth-2. He can manipulate sonic vibrations to create powerful shock waves of considerable strength, and 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 three, Cisco is a billionaire tech magnate in the Flashpoint timeline, profiting with 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 is inadvertently responsible for Dante's death; their friendship is strained for a while. However, Cisco and Barry reconcile after Cisco inadvertently alters history to the worse during the Dominators invasion. Cisco starts to use his powers more, but he refuses to utilize their destructive potential. He gains confidence that he is not on the same path as Reverb 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 also shares a budding romance with Cindy Reynolds (Gypsy), a metahuman bounty hunter from Earth-19. In the alternate 2024, Cisco lost his hands after the fight with Killer Frost, and thus the use of his powers. He replaced them with cybernetic prostheses and is dejected after Savitar's attacks has left Central City without a sense of hope.

Harrison Wells

Tom Cavanagh

Dr. Harrison Wells (portrayed by Tom Cavanagh) 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 releases dark matter energy in Central City, killing several civilians and granting 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 him in pushing his speed to the limit to come up with novel solutions to take down metahuman criminals. However, Wells has many secrets: he is faking paralysis, possesses the artificial intelligence Gideon with futuristic information, and is willing to kill to protect his protégé and cover his own tracks. Wells is revealed to be the Reverse-Flash, the mysterious speedster in a yellow suit who killed Barry's mother in the year 2000. It is also revealed that Eobard Thawne killed the real Harrison Wells, along with his wife Tess Morgan, and assumed his identity; he orchestrated the events that would turn Barry into the Flash for agenda. Eobard's plans are foiled and he is erased from existence when his ancestor Eddie Thawne commits suicide, though the Reverse-Flash's existence would linger to preserve the timeline. In season two, Eobard's last will as Harrison contains a recorded confession for Barry that clears Henry of all charges as Wells.

Season two features the Earth-2 version of Dr. 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. But Harry refused to take responsibility 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 doppelgänger'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 and also leading 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 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 supportive 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. Harry later despises his Earth-19 doppelgänger after discovering that he is not as intelligent as both him and their deceased Earth-1 counterpart, considering H.R. Wells as a moron. Harry helps Joe in protecting Iris after they arrive to Earth-2 to hide from Savitar, but they fail to stop him from kidnapping her. Harry respects H.R. after learning his sacrifice for Iris.

Season three introduces the Earth-19 version of Harrison "H.R." Wells. H.R. is one of several other versions of Harrison Wells that finds the cryptogram sent by Harry through the Multiverse and expresses interest in aiding Team Flash. Subsequently, Cisco figures out 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 more weeks to see if they could still work together, or otherwise H.R. will go back to Earth-19. H.R. 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 strives to transform S.T.A.R. Labs into a museum to maintain Team Flash's cover, after discovering how many criminals previously breached the facility. Gypsy, an enforcer from Earth-19, arrives to collect H.R. and bring him back to Earth-19, wanted for crossing dimensions. However, Gypsy is defeated by Cisco. In the battle against Savitar, H.R. disguises himself as Iris and is killed by Savitar in her place. In the alternate 2024, H.R. was a successful novelist.

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 miming version who communicates only in gestures.

Harrison Wells is an original character created for the series while Eobard Thawne is based on the DC Comics character of the same name.

Joe West

Jesse L. Martin

Joseph "Joe" West (portrayed by Jesse L. Martin) is a police detective, father of Iris and Wally West, and legal guardian to Barry Allen following Nora Allen's death and Henry Allen's incarceration.

In season one, he is one of the few who knows Barry's secret; he reluctantly becomes Barry's partner against metahuman criminals by offering him support in crime fighting. Joe also gives Barry advice on his feelings for Iris. He assists Barry's attempts to prove Henry innocent and secretly investigates Wells, suspicious of his intentions. Joe and the team ultimately discover Wells' true identity.

Season two, Joe is head of the metahuman task-force, only joined by Cisco and Patty Spivot. He relies on Cisco's inventions to deal with the super criminals and becomes a father figure to them both. Joe also struggles with his relationship with his estranged wife, Francine, who, unbeknownst to Joe, gave birth to their son Wally after she left the family. He is initially distraught after learning of Wally's existence and finally meets him at Christmas. Initially, Joe is not sure of how to be a father to Wally, but after Zoom kidnaps Wally, they become close. Joe is proud of Wally's aptitude in mechanical engineering and his need to help people. After Wally is exposed to the dark matter, Joe suspects that his son will become a metahuman.

Season three, in the Flashpoint timeline Joe is an alcoholic who is not fully committed to his job and is estranged from his children. He is unaware that Wally is the Flash. In the reset timeline, Joe and Iris are not speaking because Joe never told her that her mother was alive; however, they reconcile after Barry reveals the timeline changes. Joe fears for Wally's life after discovering Wally has dreams of being Kid Flash. After Wally becomes a speedster, however, Joe eventually accepts his son's destiny. He begins to move on from his widowhood by dating district attorney Cecile Horton. In an alternate 2024, Joe grieves over Iris' death and Wally's paralysis and catatonia.

Martin also portrays the Earth-2 Joseph West, a singer who does not share a father-son bond with Barry and actually blames him for Iris becoming a police officer. Joseph is killed by Deathstorm and Killer Frost.

Wally West / Kid Flash

Further information: Wally West and Wally West II

Keiynan Lonsdale

Wallace "Wally" West (portrayed by Keiynan Lonsdale) is Iris's unknown brother and Joe's son, described as "a bit of a wayward kid who has some attitude problems and some authority issues and is quick with a sassy remark". 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 until Iris finds out. Wally finally meets his father and sister during a Christmas party shortly before his mother dies, and he has since struggled 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, resulting in him ultimately becoming close 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 later 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, 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, much to both his father and sister's concerns. Wally also assists Cisco due to his background in mechanical engineering. Barry gradually appreciates Wally's supports and asking Wally's help to save Iris from Savitar. Though H.R. saves Iris instead after he sacrifices himself, Wally and Jay Garrick join Barry in the final battle to defeat Savitar. After Barry chooses to take Savitar's place in the Speed Force to stabilize it, he appoints Wally to be his successor as the Flash. In the alternate 2024, Wally sought revenge against Savitar shortly after Iris's murder but was rendered paraplegic and catatonic after the fight.

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.

• Robbie Amell portrays Ronnie Raymond / Firestorm, an engineer at S.T.A.R. Labs and Caitlin Snow’s fiance', 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. 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, with Ronnie occasionally taking 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. Ronnie marries Caitlin, though he 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. Ronnie is killed by Zoom for harming the Flash.
• Stephen Amell portrays Oliver Queen / Green Arrow, a former billionaire playboy and politician 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, 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. 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 three, Stein discovers that due to both Barry's and his own respective time-traveling actions, he now has a daughter, Lily, with his wife in the post-Flashpoint timeline; he never had a child due to his fear of being as neglectful as his father and his past commitments to his work prior to the timeline's reset. Martin eventually discovers that he is actually a good father to Lily in the new timeline and loves his daughter.
  • The Earth-2 version of the character is also one half of the conjoined metahuman criminal Deathstorm. This version of 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. Nora also appears as one of the Speed Force manifestations that helps Barry get to terms with her death.
  • Harrison 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 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. The two enemies, rivals and opposites would then have subsequent encounters for years, neither one of the two speedsters strong enough to defeat the other. At one point in his life, the Reverse-Flash, who had traveled to 2024, vanishes with the Flash in the midst of a "crisis". After finally discovering his nemesis' identity, Eobard murders Nora Allen after a failed attempt to kill Barry as a child, but loses his connection to the Speed Force in the process and became stranded in the past. He then transmutes the likeness of Dr. Harrison Wells as his own appearance, serving as season one's main antagonist by 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 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 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 the Flash, Cisco Ramon and Harry Wells. In order to prevent a time paradox, Eobard is sent bent back home, 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, altering some 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, which Barry is initially against. But when Barry starts losing 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 also 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 Joe West and the Flash.
• Wentworth Miller portrays Leonard Snart / Captain Cold, the son of a police officer and Lisa Snart's brother 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 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 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. Leonard is later extorted into working for his father, Lewis Snart, when he plants a bomb inside Lisa's head. 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 warns Barry of Mark's plans. Snart was in the process of a robbery the night of the particle accelerator explosion, causing the creation of Sam Scudder and Rosa Dillon into meta-humans. Scudder and Dillon seek revenge against Snart, and Barry reveals that Oliver mentioned he is traveling with some friends of theirs, called the Legends. During the alien attack, the Legends appear, prompting Barry to ask Ray Palmer Snart's whereabouts, with Ray informing him that Snart sacrificed himself to save the team, proving to be a hero. Months later, Barry recruits Snart from a point in time where he was traveling with the Legends in an attempt to steal Dominator technology from ARGUS. The two succeed, and Snart is returned to the Legends.

• Danielle Nicolet portrays Cecile Horton, the Central City district attorney and a close friend of Joe West. In season three, she and Joe begin a romantic relationship.
• 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. 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.

• 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. In season two, Henry is released from prison upon the discovery of Eobard's confession to Nora's murder. However, he leaves 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. De-powered, Barry visits his father and 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 suppressed 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. 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 learned from Harry that Henry Allen, who was murdered by Zoom, is his doppelgänger and Barry is Henry's son. Knowing this, Jay watches over Barry, and acts as a sympathetic yet stern mentor. He explains Barry that time travel can have adverse consequences and that Barry must live with his mistakes. Barry later seeks Jay's help with battling Savitar; they initially succeed in banishing Savitar to the Speed Force, he later escapes, with Jay taking his place. After being freed, Jay joins Team Flash in the final battle to defeat Savitar.
    • 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."
• David Sobolov voices Grodd, a hyper-intelligent gorilla with telepathic powers as a result of being experimented on by General Eiling under the watch of Eobard Thawne. He is sent to the Gorilla City on Earth-2 by Flash and later plans an attack to Central City with an army of the gorillas like him. However, he is defeated by Flash, Kid Flash, Jesse Quick, and Solovar, and imprisoned at A.R.G.U.S.

Introduced 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. Like her father Jesse is a science prodigy, claiming to have five majors in college, one being biochemistry. Jesse is abducted by Zoom to force Harry to obey his demands. 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 seek refuge on Earth-1 to escape from Zoom. 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, 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 is taken by Zoom. When Barry disappears due to the attempts to restore his speed, Jesse and Wally are affected by the dark matter. 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. Having been inspired by Barry, Jesse aspires to help people. After she and Barry stop Magenta together Harry is more encouraging, as he'd previously tried to discourage her, and has Cisco make her a suit similar to Barry's. After training with Barry, she and Harry return to Earth-2 to defend the Central City there, Jesse becoming Earth-2's 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, a speedster from Earth-2, who obsessively desires to become the only speedster in the Multiverse as Zoom (voiced by Tony Todd, with Ryan Handley behind the initial portrayal) and the main antagonist of season two. Hunter was a traumatized child (portrayed by Octavian Kaul) 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 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 him 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 fight the Flash of Earth-1 in order 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 seeks to corrupt Caitlin's mind into becoming like Earth-2 Killer Frost 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 summons 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." The Black Flash, who is now subjugated to the Time Wraiths, made some occasional appearances to hunt time remnants such as Savitar, and is apparently killed by the Earth-1 Killer Frost.
  • 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 Joe West's new protégée and partner, a member of the new metahuman task force at CCPD along with Cisco, 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 and acknowledges the Flash's heroism. However, she believes that having superhuman power brings out the best or the worst in people. 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, 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 is revealed that the Earth-2 version is a CSI.
• 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. After settling in Keystone City and following Wally's birth, Francine becomes sober from her addiction and a good mother to her son. 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.
