He first appears in Arrow, personally investigating a superhuman-related crime in Starling City. Barry is a fan of the Arrow's exploits and learns Oliver Queen is the vigilante; they become good friends. Sometime after Barry returns to Central City, he is struck in his laboratory by lightning which was affected by dark matter from the explosion of the S.T.A.R. Labs' particle accelerator.

Caitlin Snow

Dr. Caitlin Snow is a bioengineer who works at S.T.A.R. Labs, the daughter of scientists Thomas Snow and Carla Tannhauser, and the wife of Ronnie Raymond. She temporarily shares her body with an alter-ego named Killer Frost, and is later temporarily "replaced" with a new personality named Khione.
  • In the Reverse-Flashpoint timeline, Caitlin dates Marcus Ficus.

    Killer Frost / Frost

Killer Frost is Caitlin's violent metahuman alter-ego who was inadvertently created by Thomas during his experiments to treat Caitlin's ALS gene. In later seasons, she works alongside Team Flash as just "Frost". After being hit by Mirror Monarch's mirror gun, she and Caitlin split into two bodies. Frost briefly transforms into Hellfrost and gives her life in the fight against Deathstorm.
  • Panabaker also portrays Caitlin's and Killer Frost's Earth-2 doppelgänger, a metahuman villainess who Deathstorm's wife and works for Zoom. She did not finish medical school and became a criminal. After Earth-2's particle accelerator explosion, she developed cryokinesis and became unable to touch anyone without killing them. Her hair turned white and her lips and eyes blue.
  • In the Reverse-Flashpoint timeline, Frost is dating Mark.

    Khione

Khione is a new personality and a "third Snow sister" in Caitlin's body who emerges from the Consciousness Resurrection Chamber after its malfunction. She initially uses the alias Snow. She has only one biometric signature, making her neither human nor metahuman, and is later described as a goddess. Her powers connect her to the natural world, allowing her to reconstruct organisms, purge unnatural cells, and detect life. At the end of the series, she ascends to become the protector of the natural order and returns her body to Caitlin.

Eddie Thawne / Malcolm Gilmore / Cobalt Blue

Edward "Eddie" Thawne is a CCPD detective who is a romantic interest for Iris, a colleague of Barry and Joe, and an ancestor of Eobard.
In season one, Eddie transferred from Keystone City. He is initially jealous because of Barry's childhood bond with Iris and suspicious despite denials, though Barry and Eddie do eventually end up good friends. Eddie teaches Barry how to box which helps Barry be a capable combatant. Eddie initially sees the Flash as a menace and heads a task force dedicated to the Flash's capture, but he changes his perception due a near-death experience with the Reverse-Flash and even assisted the Flash. He later learns of Barry's secret identity and helps in an investigation of Wells as the Reverse-Flash who turns out to be his descendant. Eddie is disillusioned that Iris may eventually marry Barry until a conversation with Martin Stein when he realizes the future is not set and chooses to stop the Reverse-Flash by sacrificing himself to erase Eobard from the timeline, and his body is sucked into a wormhole. Eddie's likeness is later used by the Speed Force and Deathstorm in seasons three and eight respectively.
In season nine, Eddie is resurrected as "Dr. Malcolm Gilmore" in 2049 by the Negative Speed Force. After regaining his memories, Eddie gets manipulated into believing that he lost his chance for a family with Iris and is tempted as a new avatar for the Negative Speed Force, calling himself Cobalt Blue. However, he agrees to co-exist with Barry. With Eddie being alive, he will fulfill his destiny to his family bloodline that would ultimately conceive Eobard.
Cosnett was originally slated to portray Jay Garrick in the pilot before the character was changed to Eddie Thawne. Many speculated his character to be the Reverse-Flash in disguise due to his name and appearance.

Cisco Ramon / Vibe / Mecha-Vibe

Francisco Baracus "Cisco" Ramon is a mechanical engineering genius who works at S.T.A.R. Labs. Since season two, he operates as the superhero Vibe using metahuman visions and the ability to create breaches to other places until season five but his abilities are temporarily restored during season six for the Crisis. In season seven, he uses technology to mimic his former abilities as Mecha-Vibe and leaves Central City for a job at A.R.G.U.S. with his girlfriend Kamilla Hwang.
  • Valdes also portrays Cisco's Earth-2 doppelgänger Reverb, a metahuman villain, enforcer for Zoom and intimidating wrangler of Killer Frost and Deathstorm. He has more experience and control of his powers than his Earth-1 self, and can manipulate sonic vibrations to create powerful shock waves of considerable strength. His visor technology is used to modify Vibe's own visor.
  • Valdes also portrays Cisco's Earth-19 doppelgänger Echo, a hacker who murdered Gypsy. Breacher and his fellow Collectors thought that Cisco was responsible, but they eventually discover the true culprit and arrest him.

    Harrison Wells

Dr. Harrison Wells is, on most Earths in the multiverse, the mind and money behind S.T.A.R. Labs in Central City. He is an original character created for the series.

Eobard Thawne / Reverse-Flash

Professor Eobard Thawne is a time-traveling criminal, a future descendant of Eddie Thawne, and the archenemy of Barry Allen.

Joe West

Joseph "Joe" West is a detective for the CCPD, father to Iris, Wally and Jenna, legal guardian of Barry, and boyfriend of Cecile.
  • Martin also portrays Joe's Earth-2 doppelgänger Joseph West, a lounge singer who does not share a father-son bond with Barry and blames him for Iris becoming a police officer.

    Wally West / Kid Flash

Wallace "Wally" West is Iris's previously 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". He develops speedster abilities through Doctor Alchemy and begins assisting Barry as Kid Flash.
Lonsdale also stars as the character on Legends of Tomorrow and originally auditioned to portray Jefferson "Jax" Jackson. He did not return full-time for season five due to wanting to seek other acting opportunities; he later made guest appearances in seasons six and nine. It was always intended for Wally to be the son of Joe and brother of Iris, which differs from the character's comic history, as the producers felt it "weird" for second seasons of television series to introduce previously unmentioned cousins of established characters. The character inspired another character of the same name following DC's New 52 relaunch.

Clifford DeVoe / Thinker

Clifford DeVoe / Thinker was a mild-mannered professor turned egomaniac metahuman with super intelligence, who seeks to fix all that he deems wrong with humanity. He was foreshadowed by Abra Kadabra and Savitar as Team Flash's future adversary. He and his wife Marlize create the "Thinking Cap" and exploit the particle accelerator to power it, but its dark matter drains energy from his body and leaves him with ALS. They build a hoverchair to enhance him, but he develops a god complex, becoming apathetic and emotionless. He orchestrates Barry's release from the Speed Force to create 12 specific metahumans, who he then steals the bodies of to gain their powers. He serves as season four's big bad.
Cecile Horton is the Central City district attorney who would occasionally offer Joe legal advice. She and Joe begin dating and eventually get engaged. While pregnant with his daughter Jenna, she becomes a metahuman and develops empathic abilities. Because of this, she begins specializing in metahuman cases. While assisting Team Citizen and serving on Team Flash, she develops telekinesis and later adopts the codename Virtue with a costume inspired by Jenna's drawings. She also has an older daughter named Joanie.

Ralph Dibny / Elongated Man

Ralph Dibny is a private investigator specializing in infidelity cases and metahuman with the ability to stretch his body to superhuman lengths and sizes, also allowing him to morph into other people. He was previously a detective for the CCPD until Barry exposed him for planting evidence. He acquires his powers through exposure to dark matter and stabilizes at S.T.A.R. Labs, where Barry decides to give him a second chance. He becomes an asset to Team Flash known as the Elongated Man. He later develops a partnership with Sue Dearbon.
