Synopsis
When heroes alone are not enough… the world needs legends. Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat – one in which not only is the planet at stake, but all of time itself. Can this ragtag team defeat an immortal threat unlike anything they have ever known?

Introduction
In Season 1, Rip Hunter describes the state of the future and the death of his wife and son, the need to destroy Vandal Savage and the formation of his team. Beginning with Season 2, a new introduction is introduced for each episode featuring a different legend talking about the formation and the team's responsibility of protecting time following the Time Masters' demise. Damien Darhk takes over in the episode "The Legion of Doom" where he along with Eobard Thawne and Malcolm Merlyn plan on changing the world once they get their hands on the Spear of Destiny.

Season 1

 * "In 2166, an immortal tyrant named Vandal Savage conquered the world, and murdered my wife and child. I have assembled an elite team to hunt him throughout time and stop his rise to power. Unfortunately, my plan is opposed by the body I'd sworn my allegiance to: the Time Masters. In the future, my friends may not be heroes. But if we succeed, they will be remembered as legends."

 * "The Time Masters were an organization charged with protecting history from rogue time travelers, but they were destroyed. Under the leadership of Rip Hunter we have taken up their mantle. Sara Lance, former member of the League of Assassins, Dr. Raymond Palmer...The Atom, The Arsonist... Mick Rory, and Firestorm... The merged super form of Jefferson Jackson and myself, Martin Stein. We are the only ones left to protect history. We are The Legends of Tomorrow."

variant (narrated by Sara Lance)

 * "My name is Sara Lance. Last year, a former Time Master named Rip Hunter recruited a team of heroes and villains to save the world, and we did, but in the process we destroyed the Time Masters. Now we've taken up their mantle of protecting the timeline from time criminals. We are no longer saving the world. We are saving history. But don't call us heroes. We are legends."

variant (narrated by Ray Palmer)

 * "Time travel is real. And all of history is vulnerable to the attack of rogue time travelers. But one group travels throughout time to stop the spread of these so-called Time Aberrations and erase their damage to history. A group of outcasts and misfits. These individuals aren't heroes, they're something else. They're legends."

 * "Time travel is real, and all of history is vulnerable to attack, which is why we must travel through time to stop the 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 legends."

We are a team of outcasts and mistfits. So please don't call us heroes, we're something else. We're legends.

variant (narrated by Damien Darhk)

 * "My name is Damien Darhk. In 2016, I was murdered by the Green Arrow. But I was removed from the timeline 31 years before my death by a speedster from the future named Eobard Thawne. Together with Malcolm Merlyn, a former head of the League of Assassins, the three of us are going to locate the Spear of Destiny. A mystical object which can rewrite reality itself. With the Spear in our possession, we will change our past and our future and the world as you know it.

variant (narrated by Mick Rory)

 * "Seriously, you idiots haven't figured this out by now? It all started when we blew up the time pigs, the Time Masters. Now history's all screwed up, but it's up to us to un-screw it up. But half the time we screw things up even worse. So don't call us heroes, we're something else. We're legends. Who writes this crap anyway?
