DC's Legends Of Tomorrow Season 4 Unveils Trailer, Casts Tom Wilson And Ramona Young

More magic, more dragons, same misfits.

Such is life in season 4 of DC's Legends of Tomorrow, a trailer for which was launched at San Diego Comic-Con on Saturday. 

The footage plays out as one would expect, giving viewers a rundown of the biggest moments of season 3 (that Legends-versus-Mallus battle! the Totems of Zambesi coming together! Rip Hunter sacrificing himself, which was really sad so let's move on!) before transitioning into new peeks at season 4.

In the new episodes, the Legends must tackle yet another major problem. Constantine (Matt Ryan, who is a series regular in season 4) rocks up to tell the team that "Fugitives" are running amok. While attempting to take down Mallus (which they eventually did by smothering him to death with the furry turquoise god Beebo), the crew inadvertently blurred the barrier between worlds and guided mythical creatures into Earth's mortal realm. 

One such creature is a real-life unicorn, which Constantine, Sara Lance (Caity Lotz), Mick Rory (Dominic Purcell), Ray Palmer (Brandon Routh), Zari (Tala Ashe), Nate (Nick Zano), and Ava Sharpe (Jes Macallan) discover when they travel back in time to the swinging 1960s. 

In addition to the new animals and new areas of DC's Legends of Tomorrow season 4, the series has added two new faces: Ramona Young (Z Nation, Santa Clarita Diet) and Tom Wilson (the Back to the Future franchise). 

Young will play Alaska Yu, a total bookworm who has been described as "something of an expert in the world of the magical creatures that the Legends encounter in season 4." Could Alaska be the world's leading expert in unicorns? Or will she give Daenerys Targaryen a run for her money with everything she knows about dragons? (We say, "Por qué no los dos?") What we know for certain is that when Alaska partners with the Legends, she finally pulls her head out of the clouds and her nose out of her beloved fantasy novels "to become a kickass superhero" in her own right.

As for Wilson, known for playing Biff in the Back to the Future film series, he's set for the role of Hank Heywood, Nate's father. A former military man who worked for the Department of the Defense, Hank is completely oblivious to the fact that is son is a Legend. That father-son dynamic should make for some wonderfully screwball-y scenarios, which is right on brand for the series. 

Often heralded as the best show in the Arrowverse, DC's Legends of Tomorrow soared to new heights in season 3 by embracing its goofiness and prioritizing silly antics over serious stories. Critics and fans adored it, with Vox's Sara Ghaleb writing that the show "became its best self" in its third season. 

We can only hope DC's Legends of Tomorrow will experience another glow up in season 4, which is set to premiere on the CW on Monday, October 22 at 8 PM ET.
