San Diego's Comic-Con is sure to yield many exciting surprises. The teaser trailer for Netflix exclusive Defenders, which features the immortal voice of Nirvana's Kurt Cobain singing "Come as You Are," shows that Daredevil, Jessica Jones, Luke Cage an Iron Fist are the designated foursome to form the Defenders supergroup being apparently guided by no other than Daredevil's mentor Stick. The show is coming to Netfix in 2017 and should be all sorts of awesome as a darker, grittier take on the superhero team dynamic.
