Season 1 of DC's Legends of Tomorrow premiered on January 21, 2016.

When heroes alone are not enough… The world needs legends. Having seen the future, traveling rogue Rip Hunter assembles a disparate group of both heroes and villains to confront the unstoppable threat of the immortal Vandal Savage- a threat which not only puts the planet at stake, but all of time itself. From the creators of The Flash and Arrow comes this super hero team-up that combines characters from both shows – in addition to new heroes from the DC Comics pantheon. Featuring Arrow’s Brandon Routh as The Atom and Caity Lotz as the resurrected Sara Lance/White Canary; with The Flash’s Victor Garber as Dr. Martin Stein alongside Wentworth Miller as Captain Cold and Dominic Purcell as Heat Wave; plus, the newest heroes Rip Hunter, Jeff Jackson and the reincarnated warrior queen Hawkgirl, this singular super hero spinoff series pits the ragtag team against one of the most powerful villains in the DC Comics universe.

Season 2 of DC's Legends of Tomorrow premiered on October 13, 2016.

Season two amps up the firepower by enlisting both a league and a legion of new characters. Joining Rex Tyler aka Hourman will be other members of the Justice Society of America. And for every force of good, there is an opposing force of darkness. The Legends of Tomorrow will face off against the first ever team of Super-Villains: the Legion of Doom, including Malcolm Merlyn, Damien Darhk, Captain Cold and the Reverse Flash. After saving the world from Vandal Savage, the Legends of Tomorrow are now charged with protecting time (past, present and future) itself, taking them across history and up against a threat unlike any humanity has ever known.

Season 3 of DC's Legends of Tomorrow premiered on October 10, 2017.

In season three, DC’s Legends of Tomorrow face a new existential threat created by their actions at the end of last season. By revisiting a moment in time they’d already participated in, they’ve essentially fractured the timeline and created anachronisms all across time! Our team must find a way to return all the anachronisms to their original timelines before the time stream falls apart. But before our Legends can jump back into action, Rip Hunter and his newly established Time Bureau call their methods into question and disband the team. Challenging the Time Bureau’s authority, they recruit a hacker from the future, Zari Tomaz and continue their time travelling shenanigans, while insisting that however messy their methods may be, some problems are beyond the Bureau’s capabilities. Some problems can only be fixed by Legends.

In season seven, the Waverider gets blown up by a second Waverider…meaning the Legends are now trapped in 1925 Odessa, Texas!

Along the way, they pick up a familiar but shocking new teammate: a real-life, human Gideon, who’s knowledge of the timeline may be the key to solving all of the Legends’ problems.
