Mid Credits Scene
Earth rejoices over the repulse of the invasion, but several skeptics, including Amanda Waller, states that they got lucky this time; if the aliens or a similar threat return, the Earth has no means of advance warning. Watching the report, Batman ponders this remark...

A short time later, the heroes assemble aboard a large space station orbiting the Earth, built and launched in secret by Wayne Enterprises. The station will provide warning in advance in case of another alien invasion. Superman addresses the assembled heroes, saying that the invasion has proved to him that even he isn't powerful enough to safeguard the Earth by himself. He proposes the formation of the Justice League. Four of the other heroes agree (in his or her own way); Batman, used to operating solo, is reluctant to join a team, but assures them that he'll be on call when they need help. The last holdout is J'onn, who is near the windows by himself, gazing at the stars. When Superman goes to him, J'onn says he is the last surviving member of his race. Superman says that he can relate, and assures J'onn that he doesn't have to be alone anymore
