# Legends of Tomorrow season 3

The third season of the American television series Legends of Tomorrow, based on DC Comics characters, premiered on The CW on October 10, 2017, and ran for 18 episodes until April 9, 2018. The season follows the Legends, a dysfunctional team of time-traveling superheroes and anti-heroes, and their mission to correct their unintentional anachronisms. Set in the Arrowverse and sharing continuity with that universe's other TV series, it is a spin-off of Arrow and The Flash. The season was produced by Berlanti Productions, Warner Bros. Television and DC Entertainment, with Phil Klemmer and Chris Fedak its showrunners.
Ordered in January 2017, production began that July and ended in February 2018. Principal cast members Caity Lotz, Brandon Routh, Victor Garber, Franz Drameh, Maisie Richardson-Sellers, Amy Pemberton, Nick Zano, and Dominic Purcell return from previous seasons and are joined by new cast members Tala Ashe and The Flash alumnus Keiynan Lonsdale. Drameh, Garber and Lonsdale left the series during the season. Several of the season's recurring characters became regulars during the following season, including Matt Ryan, Jes Macallan, and Courtney Ford.
The season received positive reviews from critics who praised its lightheartedness and cast, and several felt that it was a great improvement over the previous two seasons. The series was nominated for a Best Superhero Television Series, and the season averaged 2.37 million viewers per episode.

## Overview

Following the season 2 finale where the Legends attempted to time travel with two versions of themselves aboard the Waverider had a larger impact on time than they thought. Due to this blunder, anachronisms (including objects and people) have popped up along the timeline. Rip Hunter's Time Bureau, a replacement for the Time Masters, forces the Legends to disband and resume normal lives. They are forced back into action as deputized members of the Time Bureau, however, unaware that Rip is planning to use their often-destructive tendencies for a threat bigger than the anachronisms.

In Aruba, Mick captures Julius Caesar, informs the other Legends, and returns to the bureau. After delivering the wrong man and being dismissed by Rip, the Legends steal the Waverider and capture the real Caesar. When Rip demands that they deliver Caesar to the bureau and let them fix the anachronism, the Legends return Caesar to 49 BC themselves. During the return, Caesar steals Nate's history book and uses this knowledge to conquer the world. The bureau arrives, seizing control of the operation. Agent Ava Sharpe is captured during an excursion to retrieve the book, forcing Rip to allow the Legends to fix the anachronism; he later tells Sharpe that they could be useful in neutralizing Mallus.

Sara visits Amaya and convinces her to return, to Nate's displeasure. While Nate, Ray, and Jax visit an inn, Amaya and Sara shrink and capture the tiger. Drunk and depressed about his relationship with Amaya, Nate tells Barnum about their powers. Intending to use them for his shows, Barnum captures Ray and Jax. When Nate tells the Legends about his actions, Amaya reveals why she broke up with him in 2017. While Sara engages with Sharpe on the Waverider, the Legends attack the circus and rescue their teammates (removing the anachronism). Nate reconciles with Amaya, who tells the Legends that she has begun to lose control of her animal powers; her behavior has become psychopathic.

They find Zari, who demands help rescuing her brother from prison in exchange for learning about her powers. Stein and Nate seek a solution, and Nate synthesizes a Zambesi hallucinogen. Zari uses it to have a vision of an ancestor who advises her to trust her increasing strength. Jax initiates an unplanned prison break; Zari retrieves her brother's amulet (indicating his murder by A.R.G.U.S.) and abandons the team. Ray pursues her to a campsite where her family is to meet. Kuasa attacks the two while Sharpe pursues the Waverider in the timestream. The Legends arrive and Amaya (now in control of her powers) defeats Kuasa, who vanishes using a mystical item; this implies that she is a descendant of hers.

Zari encounters Nora Darhk, a follower of Mallus who steals her amulet while working with a Victorian occult society. Rip traps the Legends on the Waverider for protection before attending Damien's resurrection, which Nora achieves with the amulet.

Stein meets Hedy Lamarr, and the other male Legends fight over Helen. The female Legends confront Helen privately. After she refuses to return to Troy because men die over her, Helen is captured by the female Legends. Stein learns that Lamarr has become a switchboard operator; because she does not invent frequency-hopping spread spectrum, the Waverider breaks down. The Legends go to Lamarr's workplace, resulting in a confrontation with Damien's forces. Lamarr tells Jax and Stein to merge, which allows them to return to their original bodies. Nora tries to drain Sara's soul but is driven off by Firestorm, leaving Sara comatose. Damien, Nora and Kuasa retreat. A sympathetic Zari brings Helen to Themyscira, instead of Troy. ||||||||

## Production

In January 2017, before the second season's conclusion, Legends of Tomorrow was renewed by The CW. Later that year, the season was given an 18-episode order. Filming began on July 6, 2017, and ended in February 2018. Season three has a genre shift, from science fiction to fantasy, and a change in tone; it is lighter than the previous two seasons. Showrunner Phil Klemmer described the season as "more in the world of the occult and monsters". Co-creator Marc Guggenheim said that he wanted to have the Legends visit new locations, including Golden-Age Hollywood and Victorian London.
The character Mallus serves as the season primary villain. As opposed to the villains of seasons one and two, Mallus was an original character created for the series rather than adapted from DC Comics. The character Gorilla Grodd serves as an secondary antagonist. He was written more sympathetically after his defeat in The Flash (as seen in the "Gorilla City" two-part episode). Damien Darhk again acted as a supporting antagonist.
In an interview with Collider Tala Ashe stated the season would revolve around mystical artifacts called totems.

### Casting
#### Main characters

Returning series regulars from the previous season included Victor Garber, Brandon Routh, Caity Lotz, Franz Drameh, Maisie Richardson-Sellers, Amy Pemberton, Nick Zano and Dominic Purcell as Martin Stein, Ray Palmer, Sara Lance, Jefferson Jackson, Amaya Jiwe, Gideon, Nate Heywood and Mick Rory, respectively. They were joined by Tala Ashe and Keiynan Lonsdale playing Zari Tomaz and Wally West, respectively. Guggenheim explained that part of the motivation for adding the Muslim character, Zari Tomaz, to the series was the "political climate" in the United States after the 2016 elections. For the episode "Here I Go Again", Amy Pemberton appeared as Gideon, unlike most episodes in which she voiced the character. Lonsdale had been a regular on The Flash.
It was the only season in which Lonsdale was a regular; he left after the season finale, citing a desire for other acting opportunities. This was the final season in which Garber and Drameh were regulars; Garber left in "Crisis on Earth X, Part 4", followed by Drameh in the following episode. While Garber wanted to resume his career in Broadway theater; Drameh's exit was a creative decision, and he returned in the season-finale "The Good, the Bad and the Cuddly". Richardson-Sellers's character, Amaya Jiwe, left in the season finale and returned the following season as Charlie.

#### Recurring and guest stars

Arthur Darvill, who played Rip Hunter in the main cast during the first two seasons, was a recurring character this season. Several actors returned in their roles from other Arrowvverse series as recurring characters, such as Neal McDonough as Damien Darhk, David Sobolov as the voice of Grodd, and Christina Brucato as Lily Stein. Tracy Ifeachor was cast as Jiwe's granddaughter Kuasa, replacing Anika Noni Rose (who voiced the character in the animated web series Vixen). Courtney Ford replaced Tuesday Hoffman as Damien's daughter, Nora, and Ford became a regular the following season. Sellers' mother, Joy Richardson, was a recurring character as Jiwe's vision-quest ancestor. Matt Ryan played John Constantine after playing the character in the canceled NBC series Constantine. Ryan became a series regular the following season. Wentworth Miller (who played Leonard Snart as a regular in season one and a recurring character in season two) returned to play the character's Earth-X doppelganger, Leo Snart / Citizen Cold. Jes Macallan, Adam Tsekhman and Hiro Kanagawa recurred as Time Bureau agents Ava Sharpe, Gary Green and Wilbur Bennett, respectively, and Macallan became a regular the following season.
John Noble voiced the season primary antagonist Mallus. The character's true form is not revealed until the penultimate-episode "Guest Starring John Noble". In that episode, Noble also portrayed a fictionalized version of himself.

## Release

The third season of Legends of Tomorrow aired on The CW in the U.S. weekly from October 10 through December 5, 2017, when it took a mid-season break.

Critics praised the season for its lighter tone and overall cast, with several calling it the best one to date.
Vox's Sara Ghaleb wrote, "The corner of The CW's Arrowverse became its best self in season three".

However, he praised the team dynamic and the overall cast. Collider's Adam Virgona praised the season's transition from science fiction to fantasy.
Screen Rant's Kath Leroy listed the season as the seventh-best Arrowverse seasons in a ranking.
