United Planets technology picks up an object moving in space at such high speed it appears as a fiery blur. Slowing down the recorded image reveals that the object is wearing an S insignia similar to what certain superheroes from the 20th century who were faster than a speeding bullet and more powerful than a locomotive once wore. The Legion of Super-Heroes go to meet another unknown object blazing through space headed straight for Earth. The giant structure enters Earth's atmosphere and Micro Lad grows to full size and tries to stop it, to no avail. Supergirl arrives and destroys the object with one punch. She tells Cosmic Boy that the Legion of Super-Heroes is just a dream. Her dream.
