Confirmed: Next week’s Heroes Reborn season finale will be a series finale.

“As far as I know there are no more incarnations of Heroes coming,” NBC entertainment chairman Robert Greenblatt told reporters Wednesday at the Television Critics Assoc. winter press tour in Pasadena, adding that it was “always the plan” to do just one season “unless [series creator] Tim [Kring] woke up one day and said, ‘Oh, I have another chapter to tell.’

“I think we’re coming to the end… of the world, maybe,” Greenblatt added with a smirk. “Stay tuned.”

The revival premiered in September to 6.1 million total viewers and a 2.0 demo rating; it resumed its season on Jan. 7 with 3.7 mil and a 1.0.

Heroes Reborn‘s climax airs Thursday, Jan. 21 at 8/7c.
