Season 2 (DC's Legends of Tomorrow)

"Time travel is real, and all of history is vulnerable to attack. Which is why we must travel through time to stop this spread of these so-called Time Aberrations and to erase their damage to history. We are a team of outcasts and misfits. So please don't call us heroes, we're something else. We're Legends."

- Season 2 opening monologue

Synopsis
After the defeat of the immortal villain Vandal Savage and the corrupt Time Masters who colluded with him, a new threat emerges. Dr. Nate Heywood, an unconventional and charming historian, is thrust into the action upon making a shocking discovery – the Legends are scattered throughout time.

Nate must find a way to rescue season one's beloved team of heroes and rogues, including billionaire inventor Ray Palmer, who has created an exosuit with the power to shrink him to miniscule size, as the Atom; Sara Lance, the White Canary, a trained assassin; Professor Martin Stein and Jefferson "Jax" Jackson, who together form the meta-human Firestorm; and Mick Rory, aka Heat Wave, a career criminal. When the Legends encounter the J.S.A (the Justice Society of America, the precursor to DC's Justice League) in the 1940s, Amaya Jiwe, aka Vixen, joins the team. While the team reunites, a mystery looms – the fate of former captain Rip Hunter.

Once reunited, the Legends continue their new mission to protect the timeline from temporal aberrations – unusual changes to history that spawn potentially catastrophic consequences. When Nate, the grandson of J.S.A. member Commander Steel, unexpectedly finds himself with powers, he must overcome his own insecurities and find the hero within himself. Ultimately, the Legends will clash with foes both past and present, to save the world from a mysterious new threat.
