Brainiac, Cheetah, and Scarecrow launch an attack on Batman, Robin, Wonder Woman, and Green Lantern as they guard a Liquid Light manufacturing plant to steal their power devices. The heroes are captured and the Legion place them on trial, while sending four android duplicates out with their devices to fight them. Bizarro and Black Manta then steal the Liquid Light and use it on a defenseless city, and Superman, Black Vulcan, and Flash battle them and try to stop the Liquid Light, which dissolves anything in its path. The Flash uses his speed to redirect the Liquid Light. Meanwhile, the captive Super Friends manage to outsmart their android duplicates, recover their devices, and join back up with the others to beat the Legion, which manages to make a quick escape.
