Jefferson "Jax" Jackson appears in media set in the Arrowverse, portrayed by Franz Drameh.
* Introduced in ''The Flash'' episode "The Fury of Firestorm", this version is a former high school football player who was injured when S.T.A.R. Labs' particle accelerator exploded and was forced to become a mechanic instead. Following Ronnie Raymond's death and due to Martin Stein's F.I.R.E.S.T.O.R.M. matrix destabilizing, the Flash and his allies find and recruit Jax to save Stein and become the new Firestorm as all three were similarly affected by the particle accelerator.
* Jax appears in the second-season premiere of '' Vixen''.
* Jax appears in ''Legends of Tomorrow''. In the first season, Rip Hunter recruits him and Stein to join his Legends and help defeat Vandal Savage. Despite Jax refusing and Stein bringing him against his will, the former grows to appreciate being part of a team. In the second and third seasons, Stein inadvertently changes the timeline and gives himself a daughter, who goes on to have a son named Ronnie. In light of this, Jax asks his teammate Ray Palmer for help in developing a formula to separate the F.I.R.E.S.T.O.R.M. matrix so the former can use Firestorm's power on his own and allow Stein to be with his family. In "Crisis on Earth-X", Stein is fatally injured while helping the Legends and Earth-1's heroes combat Nazis from Earth-X, but drinks Palmer's formula to save Jax from suffering his fate, sacrificing himself in the process. A distraught Jax leaves the Legends to heal from his grief, though a future version appears in the third-season finale to help them defeat Mallus.
