With both the CW’s “Arrow” and “The Flash” spending a majority of their latest seasons delicately setting up the cast that will appear in the network’s third superhero offshoot, the buildup is almost over. The network has announced the premiere date for DC’s “Legends of Tomorrow” with an exciting trailer that sets up the new team’s mission. 

With both of the original superhero series take a break for Thanksgiving this week ahead of their major crossover event, the network has released the first full-length trailer for the new show highlighting each member of the team and what they’re bringing to the table. The new crop of heroes includes DC Comics and CW TV characters, Atom (Brandon Routh), White Canary (Caity Lotz), Heat Wave (Dominic Purcell), Captain Cold (Wentworth Miller), Firestorm (Victor Garber/Franz Drameh), Hawkman (Falk Hentschel) and Hawkgirl (Ciara Renee). As WIRED notes, the trailer almost immediately sets up their mission in the first season. 

DC Comics baddie Vandal Savage (Casper Crump) eventually grows more powerful than the likes of The Green Arrow (Stephen Amell) and The Flash (Grant Gustin) can handle. In the year 2166, the immortal villain has taken over the entire world. A time-traveler named Rip Hunter (Arthur Darvill) seeks out some of Earth’s greatest power-players to help him travel through time and stop Savage from ever becoming the ruling dictator that he is in Hunter’s current timeline. 

Fortunately, the “Legends of Tomorrow” series won’t be without its crossovers. “Arrow” characters Oliver Queen (Amell) and the White Canary’s sister, Laurel Lance (Katie Cassidy), both appear to give the new team members a pep talk before they travel back in time to the 1970s to take on Savage. While fighting crime in different periods is a fun gimmick for a TV show, the series will also deal with the intricacies of time travel. With a majority of the “Legends” team coming from dark backgrounds it seems one struggle will be resisting the urge to change the past to benefit their own future -- but at what cost?  

Fans can expect Thursday nights on the CW to round out its already hefty schedule of superhero shows. According to TV Line, after “The Flash” on Tuesdays and “Arrow” on Wednesdays, “Legends of Tomorrow will air Thursdays starting Jan. 21 at 8 p.m. EST. The show will air along with Season 3 of “The 100” at 9 p.m. EST. As TV Line reports, the Thursday night slot for “Legends” will displace “Vampire Diaries” and “The Originals” to Fridays starting Jan. 29.
