Khanna essayed the roles of Shaktimaan and his alter ego Pandit Gangadhar Vidyadhar Mayadhar Omkarnath Shastri on the iconic series.
The actor says the new season will show childhood of the much-loved hero and will give insights about his journey.
"The new season will begin from where the previous ended. But it will also show the childhood of Shaktimaan. How he becomes a superhero through intense training from his seven gurus, and the entire process," Khanna told PTI.
Khanna, who will be reprising the role and has lost nearly eight kgs to get into shape, says most of the popular characters from the show, such as Geeta Vishwas, Tamraj Kilvish and Dr Jaikal, will also be back.
Currently, the 58-year-old actor is in talks with Doordarshan to air the new season.
Khanna feels this is the best time to come back with a show like "Shaktimaan" as the youth are becoming materialistic today.
"'Shaktimaan' was successful because it was made with honesty. Today the youth are interested in the materialistic world and are kind of lost. So this is the perfect time to bring this show," he added.
