In the early to mid-2000s, the first season of Tim Kring's Heroes worked to establish the show as a cult-hit and the series' popularity helped usher in an era of superheroes. However, after a decrease in quality and, subsequently, interest, Heroes was canceled with only four seasons under its belt. Now, Kring is bringing the heroes back to NBC in the form of Heroes Reborn, a 13-episode miniseries.

Fans of Heroes got a first look at the revival earlier this year during the Super Bowl when a short teaser debuted. Then, the first trailer was released a few weeks ago, introducing viewers to new heroes while showing the return of fan-favorites. Now, an extended trailer was unveiled during the Heroes Reborn panel at Comic-Con International 2015.

The extended version (above) features much of the footage that appeared in previously-released promos as well as the first trailer. This second trailer offers a better look at the world viewers will be returning to, which isn’t the same as when we left it. In this world people with powers are more in the public eye - and are persecuted, even hunted, because of it.

The extended trailer also gives us a better look at the return of Noah Bennet a.k.a. Horn-Rimmed Glasses (Jack Coleman) who seemingly separated himself from his life dealing with powered people. Additionally, Zachary Levi's new character, Luke Collins, is confirmed to be someone who hunts (and kills) those who admit to having powers.

In addition to HRG, other Heroes stars returning for the miniseries include Hiro Nakamura (Masi Oka), Matt Parkman (Greg Grunberg), Mohinder Suresh (Sendhil Ramamurthy) Angela Petrelli (Christine Rose) and Micah Sanders (Noah Gray-Cabey), all of whom appear in the extended trailer. As for new heroes, Miko (Kiki Sukezane), Tommy (Robbie Kay) and Carlos (Ryan Guzman) are all featured in the Comic-Con trailer.

Since it was announced, it was clear Heroes Reborn would mix new characters with returning heroes and the extended trailer reinforces that idea. It seems many of those reprising their roles from Heroes will only do so for short periods of time, with Mohinder and Angela Petrelli making brief appearances in the trailer. However, Micah's' reveal of his identity and Hiro's sword-fighting hint that their roles may certainly be worth fans' excitement.

As for the world of Heroes Reborn, it is painted as a bleak future in which those without powers are working to track down the "evolved humans" in an effort to wipe them out. In addition to the political aspect of the series, there seems to be an apocalyptic event on the horizon that only the heroes can fight.

These themes have been explored by superhero media before, both in comics and on the big screen - not to mention next year's Captain America: Civil War will deal with the consequences of organizations tracking people with abilities. That being said, though, Heroes Reborn seems to offer enough of an interesting take on the premise to interest new viewers. As for fans, the extended trailer paints Heroes Reborn as an entertaining opportunity to revisit this world and the characters that they once enjoyed (while watching a new story unfold).
