Last night, DC Comics fans got a special glimpse at the new series DC's Legends of Tomorrow with a half-hour special that debuted just after the midseason premiere of The Flash. While we get ready for the show to debut tomorrow, The CW Network has released two new trailers and a preview for the series premiere, airing Thursday, January 21 at 8 PM ET on The CW. This footage features this unique collections of heroes, villains and misfits joining forces as a team of time-travelling legends, as they go back to the 1970s.

In DC's Legends of Tomorrow, when heroes alone are not enough, the world needs legends. Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat - one in which not only the planet is at stake, but all of time itself. Can this ragtag team defeat an immortal threat unlike anything they have ever known? We see in this preview that this group was brought together to stop Vandal Savage, who is in danger of taking over the whole world in the year 2166, the year Rip Hunter (Arthur Darvill) comes from.
