War For Earth-3

The Teen Titans, the Flash and the Suicide Squad all collide on Earth-3 on the hunt for former Task Force X mastermind Amanda Waller!

As Waller tries to take over the alternate Earth and dethrone evil versions of Superman, Wonder Woman, Batman, and other heroes that rule it, her former partner-Rick Flag-arrives on E-3 bent on making Waller pay for her crimes, while the Titans and Flash hunt for a missing academy student they believe was kidnapped by Waller to form her mysterious Justice Squad.
 
As the War for Earth-3 begins to rage, Rick Flag’s new Squad—including Cheetah, Mirror Master, Peacemaker, and a parademon of Apokolips—confronts Waller with a mission to bring her home and stand trial for her crimes. But Waller didn’t go to Earth-3 alone and now the Squad must face its predecessors, including the deadly Talon, Match—a clone of Superboy—and the Justice Squad’s newest member from Teen Titans Academy. This can’t-miss edition collects the War for Earth-3 stories found in The Flash #780; Suicide Squad #13; Teen Titans Academy#13; and War for Earth-3 #1-2.
