History in the comics
The Defenders are a loose affiliation of heroes. In fact, the core four Defenders, Hulk, Doctor Strange, Namor the Sub-Mariner, and the Silver Surfer are often at odds with one another, and only band together when there is no other option available.
Initially, the Defenders allied themselves to face the menace posed by an interdimensional scientist-sorcerer named Yandroth, and his Omegatron device which threatened to destroy the world.
Thereafter, when met by circumstances in which they required assistance, the individual Defenders would often seek each other out.
Over the years other heroes have joined the Defenders such as Clea, Black Knight, Valkyrie, Namorita, Hawkeye, Nighthawk, Professor X, Son of Satan, Luke Cage, Daredevil, Thing, Yellojacket, and others.
In the Netflix series, Marvel's The Defenders, which is set in the Marvel Cinematic Universe the members of the Defenders are Daredevil, Jessica Jones, Luke Cage, and Iron Fist.
These four heroes were forced to band together to protect New York City from an ancient and evil organization called the Hand, and their leader the mysterious Alexandra.
