Complete story — includes the ending
As Supergirl joins a despondent Batgirl on top of a city building on Earth-One, trying to encourage her before she is called to rescue a plane that falls apart approaching the anti-matter wave, Pariah arrives on Earth-6 where he confronts the royal superhero family of Lord Volt, Lady Quark, and Princess Fern as the anti-matter wave destroys their world as well. Lady Quark watches helplessly as both her husband and daughter are consumed in the wave while Pariah transports her safely out of the universe.
Meanwhile, the Monitor prepares to create a new hero to help him in his quest. By firing an ion-based energy ray into an unstable star in the Vegan system in the Earth-One universe, he causes a powerful flare of solar energy to travel to Earth. It reaches the observatory of Dr. Kimiyo Hoshi, who berates her staff as she uses the telescope to observe the destructive phenomenon present. She screams as the flare strikes her and then mysteriously transports her out of the lab, leaving her fellow workers and her father wondering what happened to her.
In the dark place where the Psycho-Pirate is taken prisoner, the shadowy figure watches on the screen the Red Tornado in action and uses his power to teleport him to the same place.
On Earth-Two in the time of Camelot, Firestorm and Killer Frost (still under the love thrall of Psycho Pirate) get help from Shining Knight to protect the cosmic tuning fork planted there in that time period, as Vandal Savage watches from a window. The three heroes engage the Shadow Demons in battle, but it is all for naught as they merge and form a giant Shadow Demon. This also happens in the other time periods that the cosmic tuning forks and the Shadow Demons appear.
In the present time of Earth-One in Metroplis, the superheroes see yet another cosmic tuning fork appear, though this time with a female in a costume similar to that of Dr. Light. She tries to warn the heroes approaching her to stay away from the tower, and blasts them away with a burst of light. Katana, who understands Japanese, realizes that this Dr. Light is not their enemy, but an ally. Superman, who is able to converse in Japanese, tells Dr. Light that he knows the situation they are in and they only want to help.
As the Monitor on board the satellite watches the heroes valiantly but vainly try to protect the cosmic tuning forks, Pariah emerges to find that the Monitor was expecting him. He reveals to Pariah that he was responsible for his survival when he should have died for his deeds, but before he could say anything more, Harbinger appears, obviously not in control of herself. She strikes the Monitor with a powerful blast that sends him hurtling down platforms until he finally lands dead. Pariah mourns as he realizes that with the death of the Monitor came the death of all hope.
At that moment, the heroes of both Earths 1 and 2 can only watch as their worlds, consumed by anti-matter, fade into nothingness.
