The CW has well and truly launched its DC Comics shared television universe. With Arrow entering production on its fifth season, The Flash potentially turning its entire universe (and, subsequently, the universes of its fellow series) on its head, Legends of Tomorrow seeing plenty of shake-ups, and Supergirl arriving on the network, The CW’s DC heroes have plenty going on. In terms of Legends of Tomorrow, the show’s first season finale wrapped up their initial mission - the defeat Vandal Savage (Casper Crump) - and introduced a new hero: Rex Tyler a.k.a. Hourman (Patrick J. Adams).
Through completing their mission, Rip Hunter and his crew of the Waverider also destroyed the Time Masters - led by the Time Council that guided the events of past, present, and future through the Oculus. So, with Rex introducing the Justice Society of America to Legends of Tomorrow, and the Time Masters gone, that leaves Rip and his team with an entirely new mission when season 2 kicks off.
While speaking to EW, Legends of Tomorrow executive producer Marc Guggenheim teased their new directive:
“In many ways, the season finale of season 1 set up the new mission statement for season 2. Like Rip says at the end of the season finale, there basically are no more Time Masters. We basically have to be the Time Masters.”
Of course, the season 1 finale of Legends of Tomorrow left Rip and those remaining members of the Waverider team - since Captain Cold (Wentworth Miller) sacrificed himself to destroy the Oculus and Hawkman (Falk Hentschel) and Hawkgirl (Ciara Rneée) decided to live their lives elsewhere - with the task of patrolling time in lieu of the Time Council. While this is likely the mission to which Guggenheim is referring, Rex Tyler threw a wrench in Rip’s plan when he announced that he had been sent back in time by Mick Rory (Dominic Purcell) to prevent their departure.
Still, it’s likely Legends of Tomorrow season 2 will start off with the Waverider team either attempting to maintain order in the time stream or trying to prevent the dangerous event that Rex Tyler foretold. Though we may not know much about this particular mission, we do have some idea of who will be joining Rip on the Waverider since Nick Zano joined the cast as Citizen Steel and Maisie Richardson-Sellers will don the mantle of Vixen.
Additionally, Guggenheim previously teased that season 2 of Legends of Tomorrow will feature a "slow reveal" when it comes to the main villain. So it's likely whatever mission the Waverider crew start off with won't lead them directly to the season's antagonist - not right away, at least. That said, as we get closer to fall premiere season, more details about the show's sophomore outing will undoubtedly surface. In fact, we'll likely learn more during Comic-Con International in San Diego later this month, where Legends of Tomorrow will be featured on a panel.
The Flash season 3 will premiere Tuesday October 4th at 8pm on The CW, Arrow season 5 will premiere in the same timeslot on Wednesday October 5th, Supergirl season 2 on Monday October 10th, and Legends of Tomorrow season 2 on Thursday October 13th.
