 Bizarro has a plan to combine three rare elements and create a ray that will turn the Legion into giants. Sinestro and Bizarro travel to the moon for one element while Captain Cold and Toyman travel to Athens for the second. The Superfriends stop them and capture the four without realizing this is exactly what the Legion wanted. They escape and use the Justice League computer to fuse the elements and create the ray. The four become giants and banish the Superfriends from the Earth and begin their plans of world domination.
