Fan Casting The Flash: Split Speed

Barry Allen, with Ted Kord and Ryan Choi, helps launch a mentorship program for young meta-humans. But when a violent surge of blue lightning erupts downtown, Barry races to the scene, finding Officers Eddie Thawne and Ralph Dibny facing a large storm. As Barry speeds into it, he's hurled into the Speed Force, vanishing. Meanwhile, Wally West trains two new recruits: 16-year-old Jessica Quick, a speedster born from a chemical storm, and 17-year-old Ronnie Raymond, fused with Dr. Martin Stein as Firestorm. They hear of Barry’s disappearance and rushes to investigate. Eddie recalls nothing—just blue lightning. Trapped in the vast emptiness of the Speed Force, Barry meets a mysterious figure: Savitar. He claims to be the Future Flash—an echo of the Barry who once tried to save his mother, then stopped himself. That discarded version of Barry was abandoned, forced to evolve. Now he’s returned. Barry awakens in a cell. Outside, Savitar impersonates him, creating chaos. As Ted, Ryan, Eddie, Jessie, Wally, Ralph, and Ronnie confront him, he warns their world is broken—and he's building a new one. Jessie and Wally attempt to disrupt the storm. In his cell, Barry phases through, racing to help. He finds Wally running at breakneck speed inside the storm. Savitar begins to unravel, destabilized by the paradox. Barry can't match Wally’s speed. He watches as Wally and Savitar vanish in the lightning. The storm fades. Barry falls to his knees, his friend gone, sacrificed to save the world.
