The Flash Season 3 Story

Here’s the official synopsis for the season:

Until recently, 26 year-old Barry Allen (Grant Gustin) lived a normal life as a perpetually tardy C.S.I. in the Central City Police department. He was secretly in love with his best friend, Iris West (Candice Patton), daughter of Barry’s surrogate father, Detective Joe West (Jesse L. Martin). Joe adopted Barry fifteen years ago after Barry’s mother was murdered and Barry’s father, Henry Allen, received a life sentence for the crime – though Barry always maintained that a mysterious “Man in Yellow” was responsible. Then the S.T.A.R. Labs Particle Accelerator exploded, creating a dark matter lightning storm that struck Barry, bestowing him with superspeed and making him the fastest man alive. But Barry wasn’t the only person who was given extraordinary abilities that night. The dark matter also created meta-humans, many of whom have wreaked havoc with their powers on the city. With the help of his scientist friends at S.T.A.R Labs, Caitlin Snow (Danielle Panabaker), Cisco Ramon (Carlos Valdes), and Dr. Harrison Wells (Tom Cavanaugh), Barry began a journey as The Flash to protect the people of Central City from these powerful new threats. With this team, Barry was finally able to defeat the Man in Yellow, aka The Reverse Flash, but in their epic battle, a Singularity was ripped in space and time that threatened to destroy them all.

After successfully closing the Singularity from destroying Central City, Barry thinks he’s seen the worst… but the arrival of Jay Garrick (Teddy Sears) reveals that the Singularity actually opened portals to an alternate Earth, known as Earth-2, which is being terrorized by a formidable evil speedster named Zoom. As Zoom sends an army of Earth-Two meta-humans to Earth-1 to defeat Barry, he receives unexpected assistance from the Earth-Two doppelganger of his former mentor, Harrison Wells. Meanwhile, Cisco discovers that he, too, was affected by the dark matter of the Particle Accelerator and must come to terms with his newfound powers. As Barry struggles to juggle life as a hero, he opens his heart to Patty Spivot (Shantel VanSanten), a spunky detective paired with Joe West, but realizes just how hard it is to find happiness when the lives of everyone you love are at stake. He finds some solace in the companionship of his father, Henry Allen, who was freed from a wrongful life sentence… but when Zoom kills Henry before Barry’s eyes, Barry’s newfound stability is shattered.

Blinded by anger, Barry unwittingly plays into Zoom’s game and uncovers the evil speedster’s true goal: to destroy all Earths in the multiverse. In the race of his life, Barry ultimately gets the upper hand against Zoom and defeats his nemesis. But unable to celebrate victory, Barry makes a world-shaking decision and speeds back in time to the night his mother died to stop Reverse Flash from killing her, irrevocably changing his past and redetermining his future.

Showrunner Andrew Kreisberg confirmed that we will be getting a two-part episode of The Flashset in Gorilla City. (Presumably this is not the two-part The Flash/Supergirlcrossover we are also getting this season, but kind of want that to happen just to find out what Grodd’s singing voice might be like…)

Kreisberg told those gathered at last week’s TCA summer press tour (via Collider): “Yes, we’re going to be doing a two-part episode that takes place in Gorilla City.” (Does this mean we will be back on Earth-Two? Can we hang out with Earth-Two Barry and Iris again? They were fun.)

There’s also the chance that they could adapt a really famous story from the comics for The Flash season 3, but that seems like it might be more at home as a season 4 or 5 thing to me. 

The Flash Season 3 Villains

Todd Lasance (Spartacus: War of the Damned) played The Rival. Hopefully he’ll be back.

In the comics, The Rival — aka Dr. Edward Clariss — is a professor who believes he has recreated Velocity-9, the chemical that enhances Jay Garrick’s super speed. When no ones believes him, he experiments on himself and takes to the streets as a darker version of The Flash to prove it.

We have more details on The Rival right here.

The Flashexecutive producer Todd Helbing talked to IGN about how Savitar — yet another evil speedster to plague Barry Allen — will differ from the villains we’ve seen previously on The Flash.Helbing teased:

Savitar is more of a psychological villain in a weird way. I think the Hindu word for Savitar means God of Speed; he’s all about speed. Everything about this guy is different. I can’t go into super detail, but he’s not like Zoom or Reverse Flash.

We wrote more about Savitar right here.

As for how Dr. Alchemy, the other big bad at play in The Flashseason 3, might come into play, Helbing teased: “I’ll just say that Dr. Alchemy’s plan and Savitar’s plan are not much different.” Could these villains be working together? Personally, I’d like to see a villain team-up after so much solo villain-y in the first two seasons of the superhero show (anarchistic Zoom garage bands, aside).

We wrote about the history of Alchemy right here.

Eagle-eyed comic book fans will have noticed the resemblance between the melty-faced Zoom from the end of The Flash‘s season 2 finale and a comic book character known as The Black Racer (aka The Black Flash). In the comics, this black-suited and facially-disfigured figure is essentially the Grim Reaper of speedsters, and he looms in the Speed Force to signify someone speedy’s death.

Was this nod deliberate? Could Teddy Sears’ Zoom return as The Black Racer? As it turns out, the answer to both of those questions is yes.

“Obviously, we did that on purpose,” executive producer Andrew Kreisberg has told EW. “We love working with Teddy. He’s such an amazing actor and amazing person, and was so much a part of the success of the show last season.”

“There aren’t any immediate plans for that [storyline], but you can’t keep a good Black Flash down, so I’m sure we’ll be seeing him in the future,” Kreisberg added.

The Flash Season 3 Kid Flash Details

Check out the Kid Flash costume, which is somehow even more faithful to the comic book version than Barry’s costume is. This looks really great.

Note the lightning emblem, which looks quite a bit like the version of the emblem Wally/Flash wore on the Justice League Unlimited animated series.

The Flash Season 3 Cast

Tom Felton (yes, that Tom Felton, Draco Malfoy himself) is Julian Albert. An earlier description of the character that surfaced before Felton’s arrival offered some other clues. Dorn is another CSI at Central City PD “who suspects there’s more to Barry than just his good guy reputation.” 

Ad – content continues below

TV Line described the (then unnamed) Julian as “Barry’s slightly older, slightly geekier contemporary, a guy who is as smart as he is intuitive.” He “doesn’t buy Barry’s nice guy routine” and starts doing some investigating “all while concealing some secrets of his own.”

It only took two seasons, but The Flashhas cast Susan Walters (of Vampire Diariesfame) as Dr. Carla Tannhauser. According to Entertainment Weekly, in addition to being Dr. Snow’s doctor mom, Carla is “a world class biomedical engineer and CEO of a major research company.”

As was hinted at when Caitlin had a chat with her Earth Two doppelganger, Killer Frost, in season 2, Caitlin doesn’t have the best relationship with her mom. Caitlin finds her mom cold and distant, while Carla sees her daughter as an ungrateful rebel.

The Flash season 3 has added to new villains to the rogues gallery: Top, who will be played by Ashley Rickards (MTV’s Awkward), according to E! Online, and Magenta, who will be played by Joey King (Fargo), according to

If you’ve never heard of these villains before, that’s because they’re DC deep cuts. Top has the power to spin at a very high speed, and she’ll be “the Bonnie to Mirror Master’s Clyde,” reports E! Online. Magenta boasts magnetic powers and has a split personality. So not your usual rogues. Here’s a first look at Magenta, as revealed by Joey King on Twitter:
