Prologue

It was a busy day in New York City; the Avengers were taking out a HYRDA base. Suddenly everywhere around the world instead of the sky, they see a giant portal, inside which shows another Earth. On that Earth, a few minutes ago a person by the name of Batman just defeated a bunch of Joker's thugs when the people of that world saw the same thing.

As the two worlds collide, a loud shockwave happens. At that moment everything changed. The two worlds became one. The Justice Initiative consisted of the Avengers, Flash, Superman, Aquaman, Hal Jordan, and Wonder Woman. The Justice Initiative is closely monitored by the government organization known as SHIELD's smaller, even more covert division known as ARGUS.

The Avengers Initiative had taken on threats such as HYDRA, and Darksied. Batman helped, but never joined the team. Now a new threat arises.
