Marvel Entertainment unveiled a teaser for the much-anticipated Netflix series The Defenders at San Diego Comic-Con Friday. The upcoming show features a team of superheroes—Daredevil, Jessica Jones, Luke Cage, and Iron Fist—who already have their own current or planned Netflix series.

Daredevil is heading into its third season on the streaming network while Jessica Jones is preparing for its second. Luke Cage, which debuted its new trailer at Comic-Con on Thursday, makes its debut Sept. 30. Iron Fist will hit Netflix (NFLX) next year. The video streaming company has not specified a release date for The Defenders beyond 2017.

The series is a small-screen repeat of what Marvel did with The Avengers, the 2012 film that paired Robert Downey Jr.’s Iron Man film franchise with Chris Hemsworth’s Thor, Chris Evans’ Captain America, and Mark Ruffalo’s Hulk.

The first Avengers movie set box office records, leading to the sequel Avengers: Age of Ultron in 2015 and a crossover Captain America: Civil War this year, with at least two more sequels on the way.

Marvel Entertainment is owned by the Walt Disney Co., (DIS) which bought it in 2009 for $4 billion. Skeptics questioned the deal, because they were worried Disney would ruin Marvel’s cast of superheroes, while investors feared Disney had paid too much. But midway through last year, Marvel-related movies and TV shows had generated more than $8 billion in box-office revenue.
