Synopsis for "Synchronicity"
Seven weeks ago, the United States military canceled funding for Julian September's quantum mechanics projects; he retaliated by killing the general who informed him and left his laboratory with a plot for revenge.
In Snake River, Idaho, Plastic Man chases some bank robbers and is unexpectedly assisted by Aquaman, who happens to be nearby. They easily capture the criminals and head to a nearby bar where Aquaman disintegrates.
In Gotham City, Bruce Wayne is held hostage in an elevator by a terrorist desperate due to his divorce. Moments before his explosive device can kill anyone, Huntress arrives; she heard about the would-be bomber from overhearing a conversation. As she debriefs with Wayne, she also dematerializes.
Above Newark, New Jersey, Steel, Superman Blue, and Wonder Woman stop seven airplanes from crashing into one another. As the trio land, Steel explains that he heard about the potential disaster by happenstance and he vanishes.
In the Justice League Watchtower, Martian Manhunter hears Batman and Wonder Woman recount their stories, alongside Big Barda who similarly had Orion and Zauriel disappear before her eyes. He tries to get to the bottom of this mystery and contacts Oracle, who mentions that a huge wave of improbable coincidences are occurring globally, including seven supervillains who simultaneously attempted to kidnap the president, independent of one another. Flash and Green Lantern Kyle Rayner attempt to stop them but need League backup.
The JLA arrive and when they enter the White House to secure the president, Barda vanishes. September is in the Oval Office with his Engine of Chance—a device that makes improbable events occur according to his whims, particularly ones involving the number seven. Batman arrives and destroys the device immediately. Once he does, September also disappears and the President of the United States appears behind the League as a young woman.
The League tries to figure out how September's probability-bending chaos has changed events, including the past and changes that September himself never anticipated. Batman deduces that there is a global pandemic of synchronicity spiraling out from September's tampering with probability. Seven Leaguers remain (Batman, Flash, Green Lantern, Martian Manhunter, Plastic Man, Superman Blue, Wonder Woman) and the Dark Knight Detective is convinced that this number will remain stable. As he finishes explaining his theory, he too blinks out of existence—he forgot to count Oracle.
