Weirdness is a constant theme on DC's Legends of Tomorrow, but so is change. The Season 3 finale "The Good, The Bad, And The Cuddly" not only wrapped up the season-long quest to use the Zambezi totems to stop the time demon Mallus, but thanks to John Constantine's (Matt Ryan) appearance in the final scene, the Waverider is charting a new direction in Season 4: fighting magical demons.
Legends is the most unique of the four superhero series set in The CW's Arrowverse. Supergirl, The Flash, and Arrow center around their titular heroes protecting their individual fictional cities from threats - with the occasional crossover their shared universe allows. Legends has no such limits of time or destination. Season 3, especially, was an absurd free-for-all across history where our blundering heroes embraced their mission to fix the timeline, which they themselves had broken. As they hunted "time anachronisms", the Legends encountered all manner of historical figures, including Julius Caesar, Leif Eriksson, Helen of Troy, Blackbeard, Elvis Presley, and even a young Barack Obama.
The series remained in a constant state of flux, however, as the heroes rolled with whatever insanity came their way - which they themselves usually caused. Throughout Season 3, a few beloved Legends left the Waverider, some new faces came aboard, and by the end of the season, the core mission of the show shifted again into a new direction.
The Deaths And New Legends In Season 3
The roster of Legends of Tomorrow was designed to be fluid with characters constantly exiting and arriving. Much of the original Season 1 cast like Hawkman and Hawkwoman are gone. Since Season 2, the Legends have soldiered on and the core ensemble led by their captain Sara Lance/White Canary (Caity Lotz), Ray Palmer/The Atom (Brandon Routh), Mick Rory/Heatwave (Dominic Purcell), Nate Heywood/Steel (Nick Zano), and Amaya Jiwe/Vixen (Maisie Sellers-Williams) have gelled as a makeshift family. The newest Legend to board the Waverider early in Season 3 was Zari Tomaz (Tala Ashe). However, many more casting changes came throughout the season.
The desire of actor Victor Garber to return to Broadway to headline Hello, Dolly! meant that Firestorm departed the Legends, when his character Professor Martin Stein heroically died during the Crisis on Earth-X crossover event. The other half of Firestorm, Jefferson Jackson (Franz Drameh), soon followed, though a version of Jax from five years in the future returned to aid his friends in the season finale. Firestorm's replacement on the Waverider was Wally West/Kid Flash (Keiynan Lonsdale), the most underutilized character on The Flash, who quickly fit in with this motley crew. The series also benefited from a few episodes with Leo Snart/Citizen Cold (Wentworth Miller), the heroic Earth-X doppelganger of the deceased Captain Cold. Wally and Snart-X both brought cheerful presences aboard the timeship.
Although they were treated as fugitives and criminals by the Time Bureau, the new organization created by the Legends' founder Rip Hunter (Arthur Darvill), the Legends eventually became steadfast allies of the Bureau. This coincided with the burgeoning romantic relationship between Sara Lance and the Bureau's director, Ava Sharpe (Jes Macallan). Ava, who had to reconcile that she is just one of a legion of AVA clones engineered in 2046, is returning as a series regular in Season 4, along with perhaps the biggest character acquisition of the series: John Constantine. Constantine made several guest appearances in Season 3 and will join the cast full-time next season. This means Matt Ryan has now completed his remarkable leap from the star of a failed NBC series to becoming a weekly player in The CW's Arrowverse - while portraying the same character.
However, the series continued to lose Legends in the season finale. Vixen left the main cast in the season finale - once Mallus was defeated, Amaya had to set her own history on its proper course, which meant sacrificing her romance with Nate - but Rip Hunter also made the ultimate sacrifice for his team; the beleaguered time warrior hasn't been a necessary component of the series since Season 1, but his redemptive sacrifice, giving his own life so that the Legends could flee Mallus, still stung.
But cast changeover is part of the show's fabric. There are bigger shifts coming.
