This film occurs during phase four of the DC and Marvel perfect film series. The two multiverses accidentally collide after the anti-monitor and the empty hand are erased from existence. War quickly breaks out, as only one franchise can claim the now all-one multiverse, and DC and Marvel both want it for themselves. It is up to our hero to end the war by separating the two multiverses once again, so that neither one will ever be able to enter the other.
