After a long wait, one of the most popular shows of all time, "Heroes" is returning with more characters, more complex storyline and even answers to what happened in the last six years since its cancellation. "Heroes Reborn" will reconnect with the basic elements of its parent show, which will centre around a group of ordinary people with extraordinary abilities.

The events of the show depict the events from a year after the terrorist attack in Odessa, Texas and because the government holds those with extraordinary abilities--now known as Evos--responsible for the attack, they now live in hiding. Zachcary Levi and Judith Shekoni play the two vigilantes that are devoted to finding and killing the Evos.

Here is the complete list of returning and new cast members who will be seen in "Heroes Reborn":

Jack Coleman: Although Claire (Hayden Panettiere) was killed in the events after the season 4 finale of "Heroes", her adoptive father Noah Bennet will be returning for "Heroes Reborn", and is looking for answers to his daughter's death. Former employee of The Company, he is returning as a main cast member.

Greg Grunberg: The mind-controlling cop, Matt Parkman, will also return to the series, although he was seen getting hurt in the series finale while attempting to kill Sylar (Zachary Quinto).

Sendhil Ramamurthy: The Indian genetics professor Mohinder Suresh, who took up his father's research into evolved humans, will be seen in a guest role in "Heroes Reborn". Evos will meet this brilliant doctor to try and save the world and mankind.

Jimmy Jean-Louis: RenĂ©, best known as The Haitian, will also return for "Heroes Reborn". He used to be an associate of Noah Bennet in the original series. 

Cristine RoseAngela Petrelli--the last surviving founder of The Company--will be seen in guest role in the upcoming series, hopefully helping the young Evolves humans in saving humanity.

Noah Gray-Cabey: Son of Nicki Sanders and DL Hawkins, Micah Sanders, who was last seen in "Heroes" season 3 will also be seen in the 2015 series. Now all grown up, the child prodigy will be seen in a guest role, at least initially.

Masi Oko: It is confirmed that he will reprise his role as Hiro Nakamura for three episodes in "Heroes Reborn", but it was not easy for him commit to that either. It was the involvement of many interested parties, including the Japanese government that allowed Oko to be in the show. He has revealed that Hiro, although not as hardened as the Future Hiro (from "Heroes" alternate reality), is more mature in the upcoming show that you would remember him.
