As for what kind of shape the show might take? Well, that's another story. The showrunners have made it clear that not everyone will make it out of season one alive. So who knows what the team will look like when Legends of Tomorrow Season 2 comes around...it could be pretty different!
Legends of Tomorrow executive producer Phil Klemmer spoke with IGN, and he told them how they're "determined to make every part of Season 2 feel like its own show. Episode 201 will very much be a new pilot with new good guys, new bad guys, new stakes, new dynamics, new goals. The team will basically have to find a new purpose."
Mr. Klemmer elaborated that the second season will see the team "no longer going to be hunted by Time Masters. They're no longer going to be burdened with having to save the world. It's no longer going to be about saving Miranda and Jonas... it's going to have a much, much different tone because our Legends are going to have a totally different purpose... There will be new faces and new everything."
Legends of Tomorrow Season 2 Cast and New Characters
Any chatter about this becoming an anthology-type show with a totally different roster is probably still premature. But TV Line reports that the May 19th season finale will drop "a beloved superhero from the DC canon" on fans. They say whoever it is has a "mysterious agenda" and that's what will fuel Legends of Tomorrow Season 2.
Who could it be? My first guess is always going to be Booster Gold, but that seems a little less likely considering that there's a movie in development for him. But when they say "beloved" it would seem to indicate that it's someone a little more high profile than some of the folks we're already associating with the Legends name, so...who knows?
