Legends of Tomorrows first season follows Time Master Rip Hunter (Arthur Darvill) in his mission to stop Vandal Savage (Casper Crump) from killing his wife and child and destroying the world. To help him, he forms a team of Legends consisting of Martin Stein (Victor Garber) and Jefferson Jackson (Franz Drameh) / Firestorm, Ray Palmer / The Atom (Brandon Routh), Sara Lance / White Canary (Caity Lotz), Kendra Saunders / Hawkgirl (Ciara Renée), Carter Hall / Hawkman (Falk Hentschel), Mick Rory / Heat Wave (Dominic Purcell), and Leonard Snart / Captain Cold (Wentworth Miller); with the A.I. Gideon (Amy Pemberton) providing assistance. By the end of the season, Snart sacrifices himself to save the Legends and Kendra and Carter depart following Savage's defeat.

The second season focuses on the remaining Legends fixing "aberrations" in time as well as confronting the Legion of Doom, composed of Eobard Thawne / Reverse-Flash (Matt Letscher), Damien Darhk (Neal McDonough), Malcolm Merlyn (John Barrowman) and a time-displaced Snart. Along the way, they are joined by historian Nate Heywood / Steel (Nick Zano) and Justice Society of America member Amaya Jiwe / Vixen (Maisie Richardson-Sellers). Though the Legends defeat the Legion, they accidentally destroy time and Rip disappears under mysterious circumstances.

The third season sees the Legends repairing anachronisms across the timestream. In addition, they also face opposition from Rip's Time Bureau and a demonic entity called Mallus (John Noble), whose disciple, Nora Darhk (Courtney Ford), has resurrected her father Damien and Amaya's future granddaughter Kuasa (Tracy Ifeachor). During the crossover storyline "Crisis on Earth-X", Stein is killed; as a result, Jefferson loses his powers and chooses to leave the Legends. The team gains new allies in computer hacker Zari Tomaz (Tala Ashe), speedster Wally West / Kid Flash (Keiynan Lonsdale), and Time Bureau agents Ava Sharpe (Jes Macallan) and Gary Green (Adam Tsekhman). In the end, Rip dies fighting Mallus while Amaya and Wally depart following the demon's defeat.

In the fourth season, the Legends must capture a group of mythical creatures that were released when they freed Mallus. Along the way, they must also stop the demon Neron from unleashing Hell on Earth. The team is joined by occult detective John Constantine (Matt Ryan), shapeshifting fugitive Charlie (Maisie Richardson-Sellers), Kaupe Mona Wu (Ramona Young), and a reformed Nora. After changing the timeline while defeating Neron, Zari is erased from the team and replaced by her brother, Behrad Tarazi (Shayan Sobhian).

In the fifth season, the Legends track down and stop evil historical figures called "Encores" after they are resurrected by Astra Logue (Olivia Swann), whom Constantine accidentally sent to Hell. Along the way, they discover Charlie is actually Clotho of the Fates, who is being hunted by her sisters, Lachesis (Sarah Strange) and Atropos (Joanna Vanderham), for destroying the Loom of Fate. Though Mona leaves the Legends to start her writing career and Ray and Nora also leave after getting married, Ava and Gary join the team after the Time Bureau gets shut down, the new Zari from the changed timeline joins them, and Astra ends up joining the team after the Fates betrayed her. The team regains their memories of the old Zari when they learn she has been transported to the World Between Worlds in the Air Totem however she cannot co-exist with her counterpart for too long as her timeline will bleed into the new one, risking Behrad's life. After defeating her sisters, Charlie departs to reunite with her old band.

In the sixth season, the Legends deal with rescuing Sara from the scientist human shapeshifter Bishop (Raffi Barsoumian) while dealing with alien creatures released by Sara in different times. The team is joined by alien hunter Esperanza Cruz (Lisseth Chavez). Zari Tomaz learns she can switch places with her counterpart in the Air Totem, allowing her to rejoin the team on a part-time basis and continue dating Nate. John and Mick depart following Bishop's defeat.

Main characters Martin Stein / Firestorm

Professor Martin Stein (portrayed by Victor Garber as an adult; main: seasons 1–3; guest: season 7) (portrayed by Graeme McComb as a young man; guest: seasons 1–3) is a faculty member from Hudson University and nuclear physicist focused on transmutation, who is also half of the character Firestorm with Jefferson Jackson. Stein is also Ray Palmer's former college professor. Initially time travels for intellectual pursuits and adventures with his wife Clarissa's blessing; however, after accidentally altering his own history resulted in his fatherhood in season two and becoming a grandfather following his daughter's pregnancy in season three, Stein discovers happiness that he and Clarissa had never experienced in the previous timeline and desires to be with his family, ultimately seeks to separate himself from the F.I.R.E.S.T.O.R.M. matrix, with help from Jax, Ray, Harry Wells, Cisco Ramon, and Caitlin Snow.

However, during the events of "Crisis on Earth-X", Stein is badly injured during the team's escape from Earth-X when he is shot by two Nazis and dies separating himself from the F.I.R.E.S.T.O.R.M. matrix. The Legends, Team Arrow, Team Flash, Supergirl, and Alex Danvers avenge Stein by defeating the Earth-X armies that are led by Overgirl and Dark Arrow and killing their leaders, though Eobard Thawne gets away.

Following Stein's death, his younger 1992 self is accidentally displaced in the Norsemen era with a Beebo toy, reveals details of Stein's change to his past during Hanukkah after his last encounter with his younger self in 1987 in the process. After taking his future self's advice, young Stein leads a fulfilling marriage with Clarissa following the couple's daughter Lily's birth, with him being a devoted father, therefore young Stein and his wife are living a much happier lives than what would have been without interfering Stein's destiny. The Legends end up saving him and getting him back to his own time with a replacement Beebo for his daughter. Becoming aware of his fate in 2017, young Stein decides not to learn the details of his impending death and avert it, knowing that he would die in the age of 67 hence a senior; he gathers that he would already lived his life to the fullest by then and even if he alters the event it would only bought himself a little time anyway due to being elderly. He resolves to treasure the life he has as a husband and father, and advises Jefferson to move on from his future self's death.

In season seven, Gideon encounters a memory of Stein at the time she suffers a virus.

The character was first introduced on The Flash. Garber left the series during season three to return to working in theatre; as a result, Stein was killed off in the "Crisis on Earth-X" crossover.

Victor Garber also portrays Henry Stein, an ancestor of Martin living in London, 1895.
