The Justice League have never met heroes like these teenagers with attitude before! When a teleporter accident brings the Mighty Morphin Power Rangers from Angel Grove to Gotham City, Batman isn't sure what to make of these masked martial artists and their highly suspicious giant robot dinosaurs. It's time to call in the DC Universe's greatest heroes -- the Justice League! But the League and the Rangers will have to get over their distrust quickly, because the fate of two worlds is on the line! When the Power Rangers crossed between worlds, they weren't alone -- Lord Zedd came with them. And when Zedd meets Brainiac, neither the DC Universe nor the Rangers' home Earth is safe. But when these two mighty teams join forces, they morph into a fighting force like neither world has ever seen!
