| During Barry Allen’s retirement celebration in 2035, Barry, Bart Allen, and Iris West-Allen are ambushed by Girder, who brutally kills Barry and Iris. Enraged, Bart retaliates and kills Girder, only to be stripped of his speed and arrested by the Central City Police Department (CCPD), now led by an alternate version of Cisco Ramon as captain. Facing a prison sentence, Bart is freed at the urging of Max Mercury, who gained Speed Force abilities from Barry in 2023. However, Bart is released without access to his speed, leaving him powerless. Meanwhile, Owen Mercer, a rising CSI and son of the late Captain Boomerang, investigates the crime scene and is shocked when Girder’s body mysteriously vanishes in a strange purple mist. One year later, Bart dedicates himself to protecting Central City through other means, determined to prevent others from suffering the same loss he endured. Max joins forces with Wally West, who vows to honor Barry’s legacy, while Bart remains determined to reclaim his speed and once again become the hero the city needs. | |||||
| 2 | "Powerful Tools" | Rachel Talalay | Eric Kripke | June 16, 2027 | |
| Struggling with his loss of speed, Bart pleads with Cisco for help in restoring his powers, but Cisco refuses, believing Bart’s actions disqualify him from being a hero. Max supports Cisco’s stance, leading Bart to seek out his cousin, Iris “Irey” West, in Star City. Though she agrees with Cisco’s judgment, she acknowledges that Bart had no other choice in the moment and agrees to help him regain his speed. Meanwhile, Max visits a dying Jay Garrick, who has lost his Speed Force connection and is suffering from terminal cancer. Jay warns that restoring Bart’s powers is possible but highly dangerous, with unpredictable consequences for the timeline. With Wally’s help, Bart convinces a reluctant Jay to attempt the risky procedure. Elsewhere, Mercer stumbles upon a mysterious portal emitting green lightning. Before he can report his findings to Cisco, he is pulled into the portal by an unidentified speedster. | |||||
| 3 | "Future Shock" | Hiro Murai | Tom King | June 23, 2027 | |
| Moments following from when Mercer was pulled into the portal, Thaddeus Thawne appears, a speedster who was previously trapped in the Spectre’s Dimension. He explains to Cisco that when he removed Bart’s powers using the metahuman cure, the destabilization of the Speed Force inadvertently opened a gateway, allowing him to escape. Seeking to gain Cisco’s trust, Thawne claims that he is a hero in his own timeline, and Cisco, believing his story, agrees to work with him, even providing him with a new suit. Meanwhile, a criminal using advanced technology to replicate metahuman abilities, calling himself "Mimic," launches an attack on Central City. Thawne quickly suits up under the new alias "Inertia" and intervenes, successfully neutralizing Mimic’s power-mimicking tech and ensuring his arrest. Elsewhere, Irey, Bart, Wally, and Jay continue investigating a way to undo the effects of the metahuman cure. Bart proposes traveling back in time to prevent Cisco from removing his speed, but Jay strongly opposes the idea, warning of the potential timeline damage. Upon returning to Central City, Bart learns of Thawne’s involvement and is horrified to discover that, in another timeline, Thawne was a mass murderer responsible for a dozen deaths before ultimately being defeated by The Flash. | |||||
| 4 | "Velocity" | Leigh Janiak | Bryan Edward Hill | June 30, 2027 | |
| Bart attempts to expose Thawne’s true nature, but Thawne anticipates his move and destroys all evidence against him. Desperate, Bart informs Cisco, only to be dismissed and threatened with arrest for spreading false accusations and trespassing on private property. Meanwhile, Linda Park-West grows suspicious of Mercer’s sudden disappearance and begins to suspect foul play, believing he was either kidnapped or murdered. As Bart struggles to prove the truth, he starts a relationship with Valerie Perez after the two go on a date. Determined to reclaim his speed, Bart defies Wally’s warnings and takes Velocity-X, temporarily restoring his abilities. Fueled by his regained speed, Bart confronts Thawne and vows to expose him, leading to a high-speed battle across Central City. However, as the Velocity-X in his system begins to wear off, Bart is overpowered and forced to retreat. Meanwhile, Cisco, secretly conducting his own investigation into Thawne, finds all evidence seemingly manipulated to frame Bart. Convinced that Bart is the real threat, Cisco declares his intention to bring him down. | |||||
| 5 | "Fractured Time" | Dan Trachtenberg | Saladin Ahmed | July 7, 2027 | |
| In flashbacks, Bart and Valerie meet in high school, forming a deep bond that eventually develops into a romantic relationship. In the present, Bart continues relying on Velocity-X to maintain his speed and confronts Cisco, revealing his regained abilities and demanding his help to stop Thawne. However, Cisco, convinced that Bart is the real threat, warns that he is coming for him "to end him once and for all." Thawne soon arrives, chasing Bart down and easily overpowering him, taunting him to "respect his superiors." Back at CCPD, Cisco questions Thawne, who dismisses Bart’s claims as baseless rumors. Meanwhile, Bart's excessive use of the speed-enhancing drug begins to take a toll on him, leading to uncontrollable bursts of rage. Valerie intervenes, helping to calm him down, but his instability worsens. When Wally and Jay discover his addiction, they urge him to stop before it destroys him, leading to a heated argument in which Bart, consumed by anger, destroys his suit and nearly demolishes his own home. Meanwhile, Linda presents Cisco with CCTV footage showing a speedster destroying evidence, planting doubt in his mind about Thawne. Elsewhere, Leonard Snart and his crew drive toward Central City, preparing for their next move. | |||||
| 6 | "Rogue’s Run" | Cathy Yan | Brenden Fletcher | July 14, 2027 | |
| As Bart and Valerie grow closer, their bond becomes unbreakable. Meanwhile, Cisco obsessively reviews the CCTV footage, suspecting Bart might be the speedster responsible for tampering with evidence but keeping an open mind. Elsewhere, Snart and the Rogues launch an attack on the Central City Bank, prompting Bart to intervene. Cisco personally attempts to stop the Rogues while also seeking to apprehend Bart, but after a chaotic battle, both parties manage to escape. During his own investigation, Thawne uncovers Bart’s true identity and confronts him, revealing that he traveled back in time to recruit the Rogues to stop the "false heroes" from ruining Central City before vanishing. Meanwhile, Jay confides in Wally that his cancer has worsened, with doctors giving him only weeks to live. Determined to capture Bart, Cisco uses intel on the Rogues' next heist at McCulloch Tech, where they plan to steal a battery device capable of resurrecting deceased metahumans. Bart arrives to stop them, successfully convincing the Rogues not to disrupt the timeline further—until his speed suddenly gives out. Thawne arrives, brutally killing the Rogues before mercilessly beating Bart. As Cisco arrives and demands that Bart be arrested instead, Thawne shocks them both by murdering Valerie, vowing to restore the Reverse-Flash before disappearing. Devastated, Cisco tearfully reconciles with Bart, apologizing for believing Thawne and promising to help restore his speed. A week later, Jay succumbs to his cancer, and at his funeral, Wally vows to find a cure, determined to honor his fallen mentor’s legacy. | |||||

Production[edit | edit source]
Development[edit | edit source]
In September 2023, early development began on a new Flash series intended to serve as a direct sequel to The Flash (2014–2023), shifting focus from Barry Allen to his successor, Bart Allen. The creative team aimed to continue the legacy of the Arrowverse while introducing a fresh perspective by centering the narrative around Bart. Discussions initially revolved around adapting classic Flash comic book storylines, reimagining them with Bart as the lead character rather than Barry or Wally West. The goal was to showcase Bart’s evolution from an impulsive young hero into a seasoned protector of Central City, reflecting his struggles to live up to his grandfather’s legacy while forging his own path. Writers explored the idea of Bart navigating a world without Barry, facing both new threats and familiar villains reintroduced through a modern lens.
By early 2024, the structure of the series took shape, with the first season planned to consist of 22 episodes—mirroring the standard length of its predecessor in its earlier seasons. The extended format was chosen to allow deeper character development, intricate multi-episode arcs, and a balance of both serialized storytelling and standalone episodes reminiscent of classic Flash runs. Showrunners also aimed to build upon The Flash's established world while gradually introducing new characters and concepts unique to Bart’s journey. In March 2024, the team finalized the season’s overarching storyline, cementing Bart’s rise as Central City’s new speedster and setting the stage for a series that would honor the past while propelling the franchise into a bold new era.
Between March and June 2024, the creative direction of the series underwent a significant overhaul, shifting its approach to more faithfully adapt Impulse comic book storylines with Bart Allen as the lead. Initially, the show had been structured as a continuation of The Flash (2014–2023) while loosely incorporating classic Flash narratives. However, following internal discussions, the writers opted to realign the series more closely with Bart’s comic origins, embracing his unique personality, impulsiveness, and growth as a hero. This rewrite meant that instead of simply filling Barry Allen’s shoes, Bart’s journey would follow his own arc from the comics, integrating elements from Impulse, The Flash, and Young Justice storylines. The shift allowed for a more character-driven experience while still maintaining the core essence of The Flash series.
Despite the series’ restructuring, the connection to the original Flash show remained a priority for the creative team. The new series would directly acknowledge the events of the previous show, including Barry Allen’s legacy, the impact of the Speed Force, and the influence of Team Flash. Several returning characters were planned to appear, ensuring continuity between both series. At the same time, Impulse: Fast Forward was chosen as the official title, reflecting Bart Allen’s journey while differentiating it from the previous Flash show. The title emphasized Bart’s nature as an unpredictable and fast-moving hero while symbolizing his struggle to push forward in the absence of Barry and Iris West-Allen.
Alongside these changes, it was announced that the episode count would be reduced from 22 to 10, prioritizing quality over quantity. The decision aimed to avoid filler episodes and ensure a focused, streamlined narrative. Additionally, Flash showrunner Eric Wallace was removed from the project, with Warner Bros. reportedly unsatisfied with his handling of the later seasons of The Flash (2014–2023). Wallace’s tenure had been widely criticized for inconsistent storytelling and controversial creative decisions, leading to the studio’s decision to bring in a new showrunner. The replacement, whose identity was kept under wraps initially, was said to have a strong understanding of Flash lore and a fresh vision for Bart Allen’s story, ensuring that Impulse: Fast Forward would live up to both fan expectations and the legacy of its predecessor.
Writing[edit | edit source]
The writing team for Impulse: Fast Forward brought together an impressive roster of experienced screenwriters and comic book writers to craft the show's ten-episode narrative. The writers’ room featured Legion and Fargo creator Noah Hawley, who also served as the showrunner, alongside The Witcher’s Lauren Schmidt Hissrich, The Boys showrunner Eric Kripke, comic book writer Tom King, Titans writer Bryan Edward Hill, Miles Morales: Spider-Man writer Saladin Ahmed, Batgirl co-writer Brenden Fletcher, Birds of Prey and The Flash screenwriter Christina Hodson, The Flash comic writer Joshua Williamson, and Young Justice creator Greg Weisman. This diverse lineup of talent ensured that Impulse: Fast Forward balanced high-quality television storytelling with authentic comic book adaptations, making Bart Allen’s journey feel both fresh and rooted in DC lore.
As showrunner, Hawley provided meticulous direction for each episode’s script, focusing on distinct storytelling beats and character-driven moments while maintaining the fast-paced energy associated with speedster narratives. He emphasized that dialogue needed to be sharp and character-specific, ensuring that Bart’s impulsive personality, humor, and emotional growth were reflected naturally. Action sequences were also handled with precision, as Hawley instructed writers to think about how speedster fights should differentiate from standard superhero battles—favoring creative uses of speed, physics-defying maneuvers, and fast-paced banter between Bart and his allies or enemies. He worked closely with the writers to ensure each episode had a unique voice while fitting into the larger overarching story, with each writer given the freedom to inject their own style into their respective episodes while maintaining narrative consistency.
Each episode was designed to run between 45 to 55 minutes, allowing for substantial character development and action without unnecessary filler. The scripts carefully incorporated CGI-heavy sequences to elevate the show's scope without relying solely on visual spectacle. Hawley and his team ensured that CGI was written into the story organically, meaning that speed-based action scenes were integrated with character-driven stakes rather than being used purely for visual flair. Writers collaborated closely with the visual effects team to create realistic depictions of speed force abilities, time distortions, and large-scale set pieces, ensuring the show maintained cinematic-quality effects. The structured approach to CGI-driven storytelling helped the series balance high-stakes superhero action with grounded emotional moments, reinforcing Bart Allen’s struggles and triumphs throughout the season.
In multiple interviews, Impulse: Fast Forward, Hawley detailed the challenges and creative decisions behind crafting the series, particularly in how to continue The Flash’s legacy without its titular hero while making Bart Allen the central figure. Hawley admitted that the only "plausible" way to tell the story they envisioned was to begin with a tragedy that would not only remove Barry Allen from the equation but also set Bart on a deeply personal journey of redemption. He described the process as "tricky" because they wanted to honor the legacy of Barry and Iris West-Allen while creating a compelling reason for Bart’s evolution from an impulsive sidekick into a hero capable of leading his own story. Ultimately, this led to the decision to open the series with Barry and Iris’s deaths at the hands of Girder during Barry’s retirement celebration in 2035. The emotional weight of this moment, combined with Bart’s rage-fueled act of vengeance—killing Girder—served as the catalyst for the story, forcing Bart to confront the consequences of his actions when an alternate version of Cisco Ramon, now the captain of the Central City Police Department (CCPD), strips him of his speed and has him arrested.
Hawley further elaborated on the reasoning behind this direction, explaining that Bart Allen’s character has always been defined by his impulsive nature, and placing him in a situation where he acts recklessly in grief was essential for his growth. "Taking away Bart’s speed immediately after he crosses the line forces him to reflect on who he is and what it truly means to be a hero," Hawley stated. "It’s easy to be a speedster when everything comes naturally to you, but without his powers, Bart has to redefine what being a hero actually means."
As for comic book influences, Hawley revealed that while Impulse: Fast Forward wasn’t a direct adaptation of any single storyline, it drew inspiration from multiple sources across DC Comics history. He cited The Trial of The Flash as a key thematic influence, though rather than Barry being on trial for murder, it was Bart who faced the legal consequences of his actions. Additionally, Hawley noted that elements from The Return of Barry Allen played a role, particularly in how Bart grapples with living up to the expectations of his lineage without Barry there to guide him. He also referenced Impulse (1995) and The Flash: Rebirth as inspirations, blending Bart’s classic comic book personality with a modernized coming-of-age arc that would be unique to the GWU.
Despite the serious themes, Hawley reassured fans that Impulse: Fast Forward would not be a dark and gritty take on the character. He emphasized that Bart’s journey, while filled with loss and self-discovery, would also embrace the fun, humor, and high-energy storytelling that makes speedsters so beloved. "Bart is different from Barry," Hawley explained. "He's faster, he's funnier, and he’s a wildcard. This is a story about loss, but it’s also about finding yourself, learning from your mistakes, and figuring out what kind of hero you’re really meant to be."
