Heros: Origins
 

NBC on Monday announced Heroes: Origins, a spin-off series to air next season on the network.

Heroes: Origins will fill in for Heroes during breaks in the season. Six episodes are planned.

Each episode the spin-off will introduce a new character -- one of whom will be chosen by viewers through the Heroes website on NBC.com to become a cast regular the following season.

NBC is planning 30 combined episodes of Heroes and Heroes: Origins.

Heroes is returning to its Monday at 9 p.m. time period for next season.
