With the third season of Heroes currently in production, creator and producer Tim Kring is dropping a few hints about what fans can expect this fall.

“You’re going to see a lot of bad guys in this one,” Kring said. “The idea, also, is we’re playing off the idea of our characters as heroes or villains. So it’s really the duality of good and evil. … We’re playing off of this duality of good and evil. All of our characters were given these powers and possess these powers, and at some point it becomes sort of free will and human nature as to what you’re going to do with that. And all of us are given the choice to make decisions that lead us down very dark paths or towards heroic ends. And so, literally, every one of our characters gets faced with that dilemma.”

Kring told SciFi Wire that the third season of the show will delve further into the characters and their backgrounds.

“One of the things that this volume is going to do that, I think, is really going to be fun for the audience is that there were very initial sort of primal questions that the show asked,” Kring said. “Who am I? What’s happening to me? How am I connected? Where are these powers coming from? All of those questions get reframed and turned on their head in a very interesting way in this volume.”

The third season will be divided up into volumes in keeping with other seasons. The first volume will focus on the villains of Heroes, including popular bad-guy Sylar.

“Well, we have no plans of saying goodbye to Sylar right now,” Kring assured fans. “I mean, that was yet another silver lining for the strike, was Zach Quinto’s availability to us in the third volume. I mean, that was a huge thing for us to be able to have him back. As you guys know, he would have disappeared for a large chunk of the second half of season two. And so, for us, it was a big, big deal.”

The third season of Heroes hits NBC on September 22.
