List of The Flash characters

The Flash is an American television series developed by writer-producers Greg Berlanti, Andrew Kreisberg and Geoff Johns, based on the DC Comics character the Flash. The series premiered in the United States on October 7, 2014 on The CW television network. It 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 also tries to solve the murder of his mother (Michelle Harrison) by a superhuman attacker (Matt Letscher) when he was eleven. 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 motivates Barry to put his personal needs aside and use his powers to fight those who would hurt the innocent, shaping him into the Flash.

The following is a list of characters who have appeared in the television series. Many are named after (or based on) DC Comics characters.

Bartholomew Henry "Barry" Allen is an awkward assistant crime-scene investigator for the Central City Police Department, who moonlights as the Flash. He first appears in "Pilot" (Earth-1) and "Welcome to Earth-2" (Earth-2). In season one, Barry (Logan Williams) is traumatized as a child 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. Moments after an explosion at the S.T.A.R. Labs particle accelerator, he is struck by lightning in his laboratory and doused with chemicals spread by the accident. When Barry awakens from a nine-month coma, he has superhuman speed. He uses his new powers to fight crime and hunt other metahumans in Central City as the masked superhero known as the Flash while he tries to identify his mother's murderer to free his father from prison. 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. Though Barry resented Joe's scepticism about Henry's innocence in the past, he now has a close bond with Joe and asks him for advice about Iris and what to do as a heroic crime-fighter. He becomes good friends with Cisco, Caitlin and his idol, Dr. Wells, his 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 wormhole, which Ronnie stops with his own life.
