Justice League (DC Extended Universe)

The Justice League is a strike force comprised of Earth's mightiest heroes. They serve as stalwart protectors of life, dedicated to protecting the world as the first line of defense against terrestrial, extra-terrestrial, inter-dimensional and supernatural threats. Founded by Batman and Wonder Woman following the death of Superman, the Justice League was formed when Steppenwolf invaded Earth with his army of Parademons. Having lost the world's greatest protector, Batman and Diana set off to round up a team of powerful metahumans to confront the invaders and save Earth.
