Justice League of America #20 (1963)

In Justice League of America #20, our heroes face a perilous crisis on Allamar, where a strange machine has rendered the entire population comatose. Wonder Woman, the Green Arrow, and Aquaman are dispatched to deal with the disaster, but struggle to overcome the hurricane force winds surrounding the device. However, the trio's determination and teamwork prevails as they rescue the device and destroy it.

But the heroes' victory is short-lived, as a new crisis arises on the planet Ullison, where the entire population has been paralyzed by another strange machine. J'onn J'onzz, the Manhunter From Mars, the Green Lantern, and the Flash are dispatched to deal with the situation, but only success comes when the heroes work together as a team to triumph over an enormous dragon protecting the device.

The giant astronaut, who had been causing disasters throughout the story, is revealed to be a robot, and the Justice League of America figure out that it has been absorbing energy from each crisis point to broadcast back to its spaceship. The League members must come together once more to stop the robot from draining them of their powers and then send it on an eternal trip around the universe.
