Justice League (Earth-9251)

"The League leads. When there is a crisis, the other heroes and the world look to us first to deal with it, to rally others. We set the example."

- - Martian Manhunter

The Justice League is a team comprised of the majority of Earth's costumed vigilantes bent on protecting and defending the world from threats and perils beyond the scope of normal defense forces. As of 2016, the Justice League has been granted official sanctions by the United Nations following the Sokovia Accords. The team is headquartered at the Hall of Justice and formerly the Justice Tower before its destruction by the Thanagarians.

Justice Initiative
The idea of what would be the Justice League came from the Justice Initiative by S.H.I.E.L.D. Director Nick Fury. Fury proposed the idea to the World Security Council with the intention of devising a team of "extraordinary" individuals to battle possible threats beyond human defense capability. The founding members Fury drew in were Captain America, the world's first superhero, the Kryptonian hero of Metropolis Superman, the armored and invincible Iron Man, the masked crime fighter of Gotham City Batman, and the indestructible Hulk. He also designated two of S.H.I.E.L.D.'s most lethal agents, Black Widow and Hawkeye to assist.
