Heroes Reborn is set to focus strongly more on new characters, according to creator Tim Kring who revealed his future plans for the 2006 reboot in an interview.
Kring is currently working on USA's Dig, but the showrunner was able to give a few hints on what we can expect on the show.
As for the characters who played big roles on Heroes, Jack Coleman (who played Noah Bennett) is the only returning actor set to reappear on Heroes Reborn.
As Ali Larter and Zachary Quinto are apparently busy working on other projects.
All told, here are some intel you should check out per Tim Kring:
On bringing-in characters, old and new:
The vast, vast majority are brand new characters, brand new ideas. [Bringing back previous characters is] really only to give a sense of continuity and a tether to the original world. If it was all completely brand new, we’d miss certain elements that need to be there to give you that bridge to cross to something new. I approached Coleman because he was a character who had a spine through the series that allowed you to meet new characters. So he’s a character I wanted to make sure had a little part at the beginning of this thing.
On the vision of Heroes Reborn:
It takes place in a post-season 4 universe. So it will tie into some of the ideas that were left dangling.
