'Heroes Reborn' will be a 13-episode spin-off series to air in 2015, but an official cast has yet to be announced, reported Deadline.
NBC's entertainment chairman Robert Greenblatt said at a New York presentation that several of the original characters are expected to return.
"Some familiar faces from the show are bound to drop in," he said.
"We have a big mini-series called Heroes Reborn, based on one of NBC's strongest dramas in recent years. Its original creator Tim Kring will reboot the show. Plus, we'll ramp into the show with an original online series prior to launch," he added.
Panettiere recently said that she has not been contacted to appear in the upcoming reboot.
