The fastest man alive is back—and this time, time itself is the enemy. The Flash 3 (2026) takes Barry Allen on his most dangerous journey yet, where every choice could unravel the very fabric of reality. The stakes have never been higher, and the speed force has a dark secret to reveal.

The trailer opens with a fractured city—cracks forming in the skyline, lightning flashing in unnatural patterns. Barry Allen (Ezra Miller) races through the streets, but it’s not the villains chasing him this time. It’s the timeline itself, bending and breaking with every step. A voiceover echoes: “You can run, Barry, but time will catch you.”
A new threat emerges—a shadowy figure manipulating time to erase key moments from history, rewriting the timeline with devastating consequences. As the world collapses into chaos, Barry is forced to confront the dark side of the speed force. Every twist of fate has a cost, and this time, Barry must decide what—and who—he’s willing to sacrifice.

The action is faster, more chaotic. The trailer showcases stunning speed sequences: Barry racing through crumbling cities, fighting alongside alternate versions of himself, and battling time itself as it warps reality. Quick cuts show Barry colliding with the very fabric of time, leaving trails of destruction behind him.
Supporting characters return, but with a twist. Iris (Kiersey Clemons) fights to hold onto her reality while learning shocking truths about her own past. The return of Batman (Michael Keaton), now more cryptic and weathered, brings new depth to Barry’s struggle. And the mysterious villain—revealed only in shadow—forces Barry to question whether his powers are the solution… or the cause.
Visually, the film dazzles with the multiverse in full force. Time fractures, worlds overlap, and dimensions collide in kaleidoscopic chaos. The timeline itself shifts like an unstable mirage—flashes of doomed futures, broken timelines, and alternate Earths spiraling out of control.

The score is intense, blending thumping beats with eerie, distorted strings that echo the tension between heroism and inevitability. Barry’s iconic theme returns, now layered with a sense of urgency and dread.
The trailer crescendos with Barry facing an impossible decision: to save his world, he must erase his past. With the timeline collapsing around him, Barry screams, “I can’t outrun this… I can’t outrun myself.”
The screen cuts to black. The title crackles across the void: The Flash 3 (2026).
This sequel isn’t just about speed—it’s about fate, choices, and the lengths we go to fix the past. As time unravels, The Flash must learn that some things, once broken, can never be fixed.
