Netflix has unveiled the second trailer for their upcoming team-up series, The Defenders, during the show's panel at San Diego Comic-Con 2017. The Marvel Cinematic Universe launched with Iron Man in 2008, though it wasn't until a few years later that Marvel Studios expanded its presences onto television, with ABC's Agents of S.H.I.E.L.D. in 2013. In the years since then, Marvel TV has developed several more shows, namely the short-lived Agent Carter series, as well as the upcoming shows Inhumans, Runaways, Cloak & Dagger, and New Warriors.

In addition to expanding the cinematic universe on multiple networks, Marvel TV has allowed Netflix to carve out their own corner of the MCU, beginning with Daredevil in 2015, and continuing with Jessica Jones and Luke Cage in 2016, and Iron Fist and The Punisher in 2017. The reason behind Netflix developing their own pocket universe is so that they can eventually bring all their heroes together for an event series: The Defenders, which is slated to premiere later this summer.

The first trailer for The Defenders debuted earlier this year, with the streaming service having since carried out an impressive social media campaign that involves each of the characters engaging with one another. Today, Netflix debuted the show's second trailer during their panel at SDCC 2017, which provides audiences with more information as to what to expect from the event series. You can watch the trailer in the section above.

The Defenders sees the aforementioned heroes' -- Daredevil (Charlie Cox), Jessica Jones (Krysten Ritter), Luke Cage (Mike Colter), Iron Fist (Finn Jones), and potentially Punisher (Jon Bernthal) -- stories come together as they unite against the Hand (including Élodie Yung's Elektra Natchios) and other villains from each of their standalone shows, in order to protect New York City. They won't be alone, though, as many of their allies from their supporting cast will also be joining the fold, such as Foggy Nelson (Elden Henson), Karen Page (Deborah Ann Woll), Malcolm Ducasse (Eka Darville), Misty Knight (Simone Missick), and Colleen Wing (Jessica Henwick), among others.

It sure seems like The Defenders will be packed with characters from all corners of Netflix's mini-universe, though the one new character that people might be looking forward to the most is Alexandra, played by Sigourney Weaver. Although she's billed as being the head of an ancient organization and an enemy of the Defenders, Weaver has previously said that she doesn't view her character as a traditional villain, and is more of an adversary. Until the show debuts next month, we'll just have to take Weaver's word for it.

NEXT: Iron Fist Season 2 Has Been Confirmed

Marvel’s The Defenders premieres on August 18th, followed by The Punisher season 1 later this fall. Premiere dates for the new seasons of Daredevil, Jessica Jones, Luke Cage and Iron Fist have yet to be announced.
