Synopsis for "Loneliest Number"
The artificial intelligence Brother Eye continues its initiative to assimilate America's entire defense network grid. After shutting down NORAD, it dispatches dozens of OMAC units into the skies above Blüdhaven. Down below, the Karate Kid and Una try to use their Legion Flight Rings to get out of the bunker they are trapped in. As they continue their work, the OMACs swoop down and literally tear away a section of the city, elevating it into the sky.
In the Bleed, the Challengers from Beyond continue traversing the byways of the Multiverse in search for Ray Palmer. Monitor Bob reminds his colleagues how important Ray Palmer is to the crisis at hand.
On Apokolips, Jimmy Olsen emerges from one of the Fire Pits with green skin and breathing flame. He scours the underbelly of the planet until he finds the Forager, who is locked up in chains. He frees her, but the Forager pounces upon him shouting, "Jimmy Olsen must die!"
In the Quantum Universe, Monarch grows weary over watching the contestants in his Arena. He separates the wounded Batmans of Earth-40 and Earth-43, and places Batman of Earth-40 in a stasis chamber.
Back on Earth, the Pied Piper continues riding a train through Arizona towards the border to Mexico. He talks to the corpse of his dead pal, Trickster, and even begins to play his flute to while away the time. As the train approaches the border into Mexico, Piper pulls Trickster's body through a roof hatch in the car and escapes into the desert.
In deep space, Mary Marvel and Eclipso continue battling one another. Mary has her hands on the Heart of Darkness, but Eclipso quickly snatches it back from her. Repulsing her backward with a purple energy ray, Eclipso takes her leave, reminding Mary that she is now and forever alone.
