Marvel has dropped a new teaser for The Defenders just as the maddening weekend of the 2017 Comic Con kick-starts in San Diego on Friday. Marvel has also secretly crafted the first look of Frank Castle aka the Punisher in the brief video. Not only that, the added bonus of the teaser is the beautiful narration by Marvel legend Stan Lee.

The series is already jam-packed with Marvel's street superheroes — Daredevil (Charlie Cox), Jessica Jones (Krysten Ritter), Luke Cage (Mike Colter), and Iron Fist (Finn Jones). But the fans have been pondering over whether the Punisher will appear in The Defenders series or not.

As Entertainment Weekly reports, Jon Bernthal (The Walking Dead) will not appear in the Marvel-Netflix series. In the one-minute-long teaser, the Punisher says, "Looks like I arrived just in time."

"Heroes show us we don't need to be perfect to do what's right," Marvel Comic book legend Stan Lee narrates the Defenders' story beautifully as he explains why they are superheroes. "It's not about living without fear, but facing injustice."

He further says, "It's not about being powerful, but finding your calling when you least expect it.

"They show us it's okay to be vulnerable, no matter how tough you are. Because even though they're heroes, they are still human."
