The Flash is an American superhero television series developed by Greg Berlanti, Andrew Kreisberg, and Geoff Johns, airing on The CW.

It is based on the Barry Allen incarnation of DC Comics character the Flash, a costumed superhero crime-fighter with the power to move at superhuman speeds.

[1] Barry eventually discovers that his mentor Harrison Wells is actually Eobard Thawne–the Reverse-Flash–his archenemy from the future who traveled back in time to murder his mother, Nora Allen, when he was a child.

After saving Iris and defeating Savitar, Barry takes his place in the Speed Force in order to repent for his creation of Flashpoint.

The fourth season sees the team successfully bring Barry back from the Speed Force, but in the process release dark matter that turns a dozen people on a city bus into metahumans, masterminded by Clifford DeVoe, an adversary with the fastest mind alive.

During the fifth season, the team discover that Nora's presence has altered the timeline and unleashed Cicada, a serial killer bent on killing metahumans, as well as the aftermath of thwarting Thinker's plot causing ordinary items to be imbued with dark matter that turns them into Meta-Tech.

Following Rosso's defeat, Barry surviving Crisis, and the multiverse's destruction and rebirth, the team navigates the world post-Crisis all while the secret organization Black Hole and quantum engineer Eva McCulloch, who is trapped in the Mirror Dimension, move forward with their mysterious plans.

In the seventh season, Team Flash defeats Eva and creates a new Speed Force while Iris, Kamilla, and Singh escape the Mirror Dimension.

With help from Damien Darhk, Barry restores the original timeline, prevents Joe's death, and spares Thawne from his erasure by removing his speed.

The ninth and final season opens with Team Flash joining forces with former enemies in order to defeat the Red Death, who is later revealed to be Ryan Wilder from an alternate Earth.

Later, Rosso returns to infect the newly-recreated multiverse, but Barry stops him with help from Oliver Queen, John Diggle, and Wally West.

After this, Eddie, who had been mysteriously resurrected with false memories, is chosen as the new avatar for the Negative Speed Force, becoming the speedster Cobalt Blue.

Bringing Eobard, Zoom, Savitar, and Godspeed back with him, Eddie fights against Team Flash, but ultimately stands down and forms a truce with Barry.

Johns stated that the character of the Flash in the show would resemble his comic book counterpart, complete with his trademark red costume, and not be a poor imitation.

This allowed the creative team to flesh out Barry's story and his world on a bigger budget, as opposed to a backdoor pilot's constraint of incorporating characters from the parent show.

[60] It features a burgundy color scheme, a masked helmet, and gold accents throughout,[61] and went through multiple adjustments from the moment it was placed in computer renderings to the day of filming the pilot.

According to Atwood "It was all about a costume that could sell speed, Grant [Gustin] was continually moving in the suit, so it had to be designed to make that all happen visually and functionally.

This was cut down to approximately 15 minutes by episode eight, when designers were able to develop a new cowl that easily slid over Gustin's face and locked into place.

[98] Each season release contains additional features, which include: making-of featurettes, episode commentaries, deleted scenes, gag reels, and Comic-Con panels.

The website's consensus reads, "The Flash benefits from its purposefully light atmosphere, making it a superhero show uniquely geared toward genre fans as well as novices.

[135] IGN's Eric Goldman and Joshua Yehl praised the show's premise and cast after viewing a press screening copy of the pilot.

Club gave the season a B+ overall, giving praise to the pacing of the plot, the performances of the cast and the special effects, and also pointing out the series' boldness to embrace its comic book influences, something that conventional superhero shows tend not to do.

Kreisberg stated, "Barry will [already] be the Flash, he will have his team, everyone will be in that world, and we'll [sic] introducing a new set of villains that we won't be seeing on the TV show.

[165] The blog, originally based at Tumblr, features posts written by the fictional character of Cisco Ramon, at first serving as write-ups of the metahuman villains on the show.

The series, which was presented by AT&T, features Valdes and Britne Oldford reprise their role as Cisco Ramon and Shawna Baez / Peek-a-Boo, respectively.

The series, presented by Microsoft Surface, features Hartley Sawyer, Danielle Panabaker, and Candice Patton as Ralph Dibny, Cailtin Snow, and Iris West respectively.

Barry must seek help from Oliver Queen, due to his own abilities beginning to break down, in order to deal with five members of his Rogues Gallery—including Pied Piper, Weather Wizard, and Peek-a-Boo.

The novel takes place in an alternate timeline where the show's "Flashpoint" event never occurred, and The Flash must fight a villain known as Hocus Pocus who can control the minds and actions of people.

The Secret Files of Barry Allen: The Ultimate Guide to the Hit TV Show features the Flash's "top-secret notes", as well as "classified S.T.A.R.

Labs dossiers on everyone in Central City", an episode guide on the first four season of the series, and details on the life of the Flash "in Barry's own words.
