Batman and Wonder Woman unite the League

It’s been evident since the end of Batman v Superman: Dawn of Justice that if anyone can unite the League against a global threat, it would be Batman. Following the Knightmare, the Caped Crusader realized that Superman and the Kryptonians were just the first aliens to visit Earth.

He sought the help of Wonder Woman to help prevent major invasions.

And he sought the help of Amanda Waller, as seen in Suicide Squad.

And Diana Prince was there to answer the call.

So far, we’ve seen several Justice League synopses. And while the focus changes, the one thing that remains clear is that Batman and Wonder Woman are charged with bringing in all of Earth's metahumans to defend the planet. No matter how the movie ends, and no matter how many additional superheroes are added to the roster, they’ll be the ones to thank.

The trailers revealed that Bruce Wayne recruits Aquaman and Flash. It remains to be seen how Cyborg will enter the fold.
