Synopsis for Superman and Batman: "The UFO That Stole the U.S.A."
When aliens cut an Earth house in half with a ray, Superman, Batman, and Gold of the Metal Men investigate. At first, the heroes suspect a grand scale invasion of Earth, but soon Batman learns the truth from the human couple that witnessed the UFO. Unfortunately, Batman is knocked into a severe coma by the aliens, forcing Superman and Gold to take Batman to the Fortress of Solitude and heal him. Afterwards, Superman goes to space to get rid of the alien threat, but on Earth, the damage done by the aliens is repaired and Batman finally realizes that the Aliens are not enemies. With Superman gone to space, it is up to Gold to stretch his body until he reaches the Man of Steel and tell him the truth about the aliens. Superman finally gets the message and gets in contact with the aliens, who explain that they simply used Earth as a testing ground for their weapons against other alien invaders. Superman helps them and warns them not to play with other planets. In the aftermath, the heroes return to Earth and things return to normal.

Trivia
- Batman sends Superman a telegram over billions of miles into outer space using Gold's body in the form of a molecule-thin wire. This is impossible for several reasons, the first being that the simple galvanic cell Batman creates with crude compounds scraped from the ground would be insufficient to produce a great enough cell potential to transmit a telegram over such a tremendous distance, to the fact that the length and diameter of Gold's elongated body would result in such extreme electrical resistance that all voltage would have dissipated long before the telegram would have reached its intended target. Also is the preposterous fact that Batman and Gold think up this solution as an alternative to contacting Superman via radio-wave transmission, which would take too long to reach him, when a radio-wave transmission would be much, much faster at propagating itself through space than an electrical signal would be at propagating itself through any solid conductive medium. And also the fact that it's inconceivable that Gold, at any diameter, could stretch himself over billions of miles through space faster than either a radio wave or an electrical current.
