Bartholomew Henry "Barry" Allen (portrayed by Grant Gustin; seasons 1–9) is the main protagonist of the series. He is an awkward assistant crime-scene investigator (CSI) for the Central City Police Department (CCPD) who moonlights as the Flash. Barry is traumatized as a child when his mother Nora is murdered by the Reverse-Flash and his father Henry is framed for the crime. Barry tries to discover what happened that night. He first appears in Arrow, personally investigating a superhuman-related crime in Starling City. Barry is a fan of the Arrow's exploits and learns Oliver Queen is the vigilante; they become good friends. Sometime after Barry returns to Central City, he is struck in his laboratory by lightning which was affected by dark matter from the explosion of the S.T.A.R. Labs' particle accelerator. Logan Williams portrays Barry as a child (recurring: season 1; guest: season 2).

Khione (also portrayed by Danielle Panabaker; season 9) 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.[4] 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.

After regaining his memories as Eddie, learning that Eobard survived, and realizing that he lost his chance for a family with Iris, he is tempted into becoming Cobalt Blue, a new avatar for the Negative Speed Force. At the end of the series, he agrees to co-exist with Barry. His likeness is occasionally adopted by the Speed Force.

He and his wife Marlize create a "Thinking Cap" and exploit the particle accelerator to power it, but its dark matter drains energy from his body and leaves him with amyotrophic lateral sclerosis. They build a hover-chair to enhance him, but he develops a god complex and becomes apathetic and emotionless. He orchestrates Barry's release from the Speed Force to create 12 specific metahumans, who he then steals the bodies of in order to gain their powers. He serves as the main antagonist of season four.

She also has an older daughter named Joanie.

He acquires his powers through exposure to dark matter (which was set up by the Thinker) and stabilizes at S.T.A.R. Labs, where Barry decides to give him a second chance.

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."[65] Hunter was a traumatized child (portrayed by Octavian Kaul[66]) that witnessed his mother's murder at his father's hands, which triggered his bloodlust as a serial killer before he gained his speedster abilities from the particle-accelerator explosion on Earth-2. Dissatisfied, he sought to increase his speed with the Velocity serums which he soon discovered carried a fatal illness. He also traveled the multiverse and imprisoned Jay Garrick with a speed-dampening mask after he's unsuccessful in stealing Jay's speed to cure himself. Inspired to be both hero and villain, he uses Jay's name as the fraudulent Flash of Earth-2 to instill false hope, which he then takes away as Zoom. Discovering Earth-1, he plots to increase Barry's speed, sending various metahumans from Earth-2 to fight the Flash of Earth-1 while also infiltrating the team as Caitlin Snow's love interest.

After succeeding in stealing Barry's speed, Zoom brings his army of Earth-2 metahumans to conquer Earth-1 and construct a device capable of destroying the other Earths in the multiverse, to ensure he remains the only speedster. Hunter seeks to corrupt Caitlin's mind into being like Earth-2 Killer Frost and then Barry's by killing Henry in the same spot the Reverse-Flash killed Nora, convinced that they are similar because of their childhood traumas. However, Barry ultimately bests Zoom in their final fight before two Time Wraiths arrive to punish him for his crimes against the time line; they transform him into the corpse-like Black Flash enslaved to the Speed Force.
