The legacy, however, is far from finished.

The series finale, which aired in 2023, delivered a conclusive and emotional ending that brought back fan-favorite characters and resolved a storyline that had been teased since the pilot episode.

The Definitive End of The Flash: Season 9 Finale Explained

The ninth season of The Flash served as the final chapter, a 13-episode run that was designed to provide closure for the beloved characters. The decision to end the show was a mutual one, allowing star Grant Gustin and the creative team to craft a proper, definitive ending, a luxury many long-running superhero shows don't get. The final episode, "A New World: Part 4," was a powerhouse of nostalgia and new beginnings.

Key Entities and Events in the Series Finale

• The Main Villain: Cobalt Blue. The final arc introduced the Arrowverse's version of the classic comic book villain, Cobalt Blue. In a shocking twist, this villain was revealed to be a resurrected version of Eddie Thawne (played by Rick Cosnett), a character who had sacrificed himself back in Season 1 to erase the Reverse-Flash, Eobard Thawne, from existence.
• The Return of Nemeses. The finale saw a major confrontation where Cobalt Blue gathered a legion of Barry Allen's most powerful former foes, including Zoom, Savitar, and Godspeed, for a final battle against Team Flash.
• The Speed Force's New Legacy. The most significant development was Barry's final realization. Instead of hoarding the power of the Speed Force, he chose to share it. In the final moments, he gifted a piece of the Speed Force to three new individuals, ensuring that Central City would always have speedsters to protect it.
• Nora's Birth. The final scene confirmed that Iris West-Allen (Candice Patton) had given birth to their daughter, Nora West-Allen, named after Barry's mother. This fulfilled the prophecy of the future speedster from earlier seasons and provided a perfect emotional capstone to their relationship.

The ending was designed to be a definitive farewell, not a cliffhanger. It paid homage to the show's history, brought back several key players, and established that while Barry's story as the primary Flash was complete, the age of speedsters was not over. The final shot of Barry's narration confirmed his decision to pass the torch, solidifying his status as a legendary hero.

The Shocking Fate of the Arrowverse After The Flash

The conclusion of The Flash on The CW is widely regarded as the official end of the interconnected "Arrowverse." This shared universe, which began with Arrow in 2012, grew to include Supergirl, Legends of Tomorrow, Batwoman, and several others, culminating in the epic "Crisis on Infinite Earths" crossover event. With Barry Allen's story concluded, the sprawling narrative tapestry of the Arrowverse has been rolled up.

What Happened to Other DC Shows?

• Superman & Lois: This show is the last remaining DC series from the original CW slate. However, it was confirmed during its run that Superman & Lois is set on a separate Earth and is not part of the main Arrowverse continuity, making it an independent DC property. The show is also slated to conclude with its fourth and final season, bringing the era of CW's DC shows to a definitive close.
• Canceled Shows: All other Arrowverse shows, including Batwoman and Legends of Tomorrow, had already been canceled prior to The Flash's final season. This left The Flash as the last hero standing, tasked with providing the final curtain call for the entire universe.

The primary reason for the end of the Arrowverse is a shift in ownership and creative direction at The CW network and within DC Studios. With James Gunn and Peter Safran taking over the creative leadership of DC Studios, the focus is now on building the new, unified DC Universe (DCU) across film and television. This new vision simply does not include the previous Arrowverse continuity, making The Flash's ending a necessary, albeit bittersweet, transition point for DC on television.

From Speedster to Stage: Grant Gustin's Next Projects

For nine years, Grant Gustin became synonymous with Barry Allen, earning a reputation as the definitive on-screen version of The Flash for an entire generation of fans. With the TV show over, the actor has quickly moved on to new and exciting projects, proving that his career is far from slowing down.

Grant Gustin's Post-Flash Career Highlights

1. A Return to Broadway. Gustin's first major post-Flash project was a return to his theatrical roots. The actor, who has a background in musical theater, took on a starring role on Broadway, fulfilling what he called his "original dream" before landing the role of The Flash. This move was a deliberate shift away from the superhero genre to explore new creative avenues.
2. Open to Returning as Barry Allen. Despite the definitive ending of the Arrowverse, Gustin has publicly stated that he is open to reprising his role as Barry Allen in the future, should the right opportunity arise. This possibility is particularly intriguing given James Gunn's plans for the DCU, though no official plans have been announced. Fans remain hopeful for a potential cameo or return in a future multiverse-spanning project.
3. New Film and TV Roles. Like many actors who leave a long-running series, Gustin is actively pursuing new roles in film and television, looking to distance himself from the Arrowverse and prove his versatility. Industry speculation has even linked him to other potential superhero roles in the new DCU, such as Adam Strange, though these remain rumors.

The transition from a nine-year superhero commitment to new roles is a significant one, but Gustin's immediate move to the stage underscores his commitment to diverse acting challenges. His willingness to potentially return to the cowl, however, keeps a small flicker of hope alive for the millions of fans who grew up with his version of the character.

The Legacy: Why The Flash TV Show Will Never Be Forgotten

Even though The Flash is over, its impact on the superhero television landscape is undeniable. It was the linchpin of the Arrowverse, a show that successfully balanced high-stakes superhero action with genuine emotional drama, family themes, and a deep love for the source material. The series introduced countless DC characters to a mainstream audience, from Killer Frost and Vibe to Gorilla Grodd and the entire Flash Family.

The Show's Lasting Impact

• The Definitive Barry Allen. For many, Grant Gustin's portrayal is the definitive version of Barry Allen. His blend of earnestness, scientific intelligence, and emotional vulnerability resonated deeply with viewers, setting a high bar for future adaptations.
• The Heart of the Arrowverse. The Flash was the emotional center of the entire shared universe. Its crossovers, especially "Crisis on Infinite Earths," were major television events that successfully united multiple shows and characters in a way never before seen on TV.
• Focus on Family. Unlike many superhero shows that focus solely on the hero, The Flash made "Team Flash" its core. The dynamic between Barry, Iris, Cisco, Caitlin, Joe, and Wells created a sense of family that was crucial to the show's success and longevity.

In the final analysis, the answer to "is The Flash over" is a resounding yes. The series has concluded, the Arrowverse is effectively finished, and the cast has moved on to new endeavors. However, the nine-season journey of Barry Allen, the fastest man alive, remains a towering achievement in superhero television, securing its place in the pantheon of great comic book adaptations.
