Heroes producer Adam Armus has promised that “an epic battle” will take place before a leading character is killed off on the show. Speaking to SciFi Wire, Armus revealed that Adrian Pasdar’s exit from the NBC series follows the climax of the Nathan-Sylar story.

“We all know that Nathan Petrelli last year was killed, and his mind was put into Sylar’s body and shape-shifted into Nathan,” Armus said. “We made some commitments last year, and we’ve committed that there is going to be an epic battle between two characters and who’s going to win and who’s going to lose.

“That’s something we’ve been planning all this year. So we know that someone has to lose.

“This whole Sylar-in-one-body-and-his-mind-in-another with Matt Parkman, all that’s going to come to a head, because ultimately Sylar is going to win. He’s ultimately going to get out of Matt Parkman’s head and get back into his body.”

Discussing the scene, Armus revealed that it will primarily involve the ongoing battle between Nathan and Sylar, but that Peter’s involvement will be crucial.

“Who is going to be in control? And whoever loses is the one that dies,” he said. “It’s the knock-down-drag-out ‘Who’s going to win this body?’, and it’s going to be between Peter and Nathan/Sylar. And Peter’s going to be fighting for his brother.”
