It was supposed to be like any other day......the people doing their jobs as the heroes stopped the crimes of thugs and villains on the streets of their cities.....it was supposed to be a normal day...

But then, something completely strange happens.....portals began to open up and more people came pouring in, some good, some bad, and some unknown. Not only that, but the earth was greeted with more new cities from these portals and caused national confusion and craziness.

It is unknown who was responsible for this chaos and meeting of alternate timelines, but now the heroes now have more threats then they could imagine. They must now rely on each other, along with new heroes, to bring back the balance of the worlds and end the madman who had brought the worlds into one.
