Far below the surface of the dying planet Mars, the descendants of a once great race live on. Above them the majestic cities have long since crumbled and the vast canals lie buried beneath a silent sea of rust red sand. With time and water running out, Alpha 7 and the other members of the Martian armada travel the galaxy in search of a suitable planet to make their own. Their frequent reconnaissance missions and landings on our Earth have given rise to what most earth men consider "wild" stories of "flying saucers" and "little green men".
Deep beneath the stormy seas of Neptune, great cities loom majestically in the shimmering twilight of a vast and beautiful water world. Here the mighty Triton people live. Not content to see the sun as but a glimmer and the stars as tiny ripples floating on the surface of the sea above, Astro Nautilus and his band of Triton mariners venture forth to sail and chart that greater ocean, Outer Space. Often visiting our planet they land, secretly, without all human knowledge, in the very depths of Earth's great oceans.
From Olympus, largest of the great cloud cities of Venus, the mighty cloud ship Cumulus sets forth. Like a fiery comet it blazes through the blackness of outer space toward Earth. Its captain, Commander Comet, is a direct descendant of the mighty Zeus, leader of the historic first Venusian expedition to Earth, which landed near the Grecian Isles 3,000 years ago. Commander Comet's present mission is one of routine Earth surveillance, and once within the atmosphere of Earth, his ship will join the great fleet of Venusian craft that float like clouds above our planet night and day, watching undetected over our world.
From the huge red spot near the equator of the giant planet Jupiter, a great ship travels forth. On board is the mighty warrior, Colossus Rex, strongest of the strong. The colossal strength needed merely to survive the crushing pressure of the atmosphere and enormous force of gravity on his native Jupiter make him a veritable superman on other worlds. Invulnerable to attack, invincible in battle, brute strength alone is his only weapon. Yet no power in the galaxy can defeat him. We hope his mission is merely to explore the universe and not to conquer it.
Beyond the stars and star smoke of our Milky Way! Out past the shining citadels of other galaxies as numerous as stars! From a place so vast it cannot have a name, comes CYCLOPS, mighty intergalactic giant! Great Warrior of the Cosmos! In his forehead, the All-Seeing Eye. With it he can witness all that is happening anywhere in the universe. In his belt he carries two additional eyes. One can see the past, the other, the future. Gliding swiftly between the stars, through the darkest reaches of intergalactic space, he travels throughout eternity, forever seeking "more than meets the eye."
The cold and desolate planet Pluto is too far from the sun to derive its heat and, thus, the very atmosphere lies frozen and life as we know it cannot exist. But there, at the very edge of our solar system, the great Intergalactic Winds that blow between the stars carry with them great masses of cosmic energy. In the beginning, this living energy bombarding the frozen planet did itself freeze to become living matter and, thus, a mighty race of beings began. Created of energy, they can become energy at will and Electron +, from his laboratory in Electra City, can transport himself throughout the universe as a beam of light.
Although we cannot see it, the world of the 4th dimension is all around us. Right here and now! But in a different plane and dimension. GAMMA X, by activating his Time and Space Materializer, is able to break through into our 3-dimensional world and make himself visible to us! Like the many 4-dimensional beings who have visited our world before him, he is able to walk through what we regard as solid walls, appear and disappear at will, and seemingly defy the laws of gravity. Throughout history, mankind has tried in vain to explain these visitors from another dimension by falsely attributing to them some supernatural origin, never realizing that the beings we call "ghosts" are really Men of the 4th Dimension.
High above the roof of our world, the twin star ALGOL - in reality, two stars, a massive Red Giant and a Blue-White Dwarf - shines its double light upon its only planet, the tiny world of "MU." Its inhabitants, though small in physical stature, are said to possess the greatest intellect in the universe and many of them have mastered the power of mind over matter. Thus, GEMINI has built great cities by merely "thinking" them to be, and through the power of thought alone, created the Majestic Ship in which he crosses the voids of outer space to visit other worlds.
On Mercury, the planet nearest our Sun, great rivers of molten metal churn and flow past majectic cities, glowing red hot in the blinding radiance of the Sun. Here, in temperatures so great that life as we know it would be consumed in a flash, the mighty Volcan Peoples live - beings of living fire that burn eternally. Protected by suits of thermal alloy, lest the freezing cold of outerspace should snuff them out, INFERNO and The Men of Mercury travel the universe in the great chariots of fire that we call comets.
Able to transform himself at will, METAMORPHO set forth many centuries ago from the third Satellite of the great star, Alpha Centauri, to explore the universe. By taking on the physical characteristics of the inhabitants of the different worlds he visits, he is able to walk unnoticed among them and study their ways. In his travels he has changed himself into so many wild and alien forms that he has long ago forgotten what his own was like. Thus, METAMORPHO has come to know all the strange and wonderful beings in the universe and to understand the "Oneness" of all life everywhere.
Often, men exploring the deepest caves and caverns of the Earth have disappeared, never to be seen again. But freezing Artic temperatures and Magnetic Force Shields have successfully prevented mankind from discovering the really major enterences to Hollow Earth, the giant doorways located directly at the North and South Poles. It is through these giant openings that MYSTRON and The Men of Hollow Earth guide their winged ships whose awkward flapping stirs up vast Artic winds that engulf our world as they struggle to leave the heavy atmosphere of Earth and reach the smooth ether on which to glide to distant stars.
From the barren mountains of Uranus great waves of thought reach out through the blackness of outer space probing the universe. Thus, Orbitron and the men of Uranus search the stars seeking the lost knowledge of the Ancient Ones. On great ships they travel to the farthest reaches of our galaxy and beyond. Able to read the minds of men, they have collected the learning of a thousand worlds, and yet they go on searching in a never ending quest to learn that which it has been ordained no man shall ever know.
Saturn is the most beautiful of all the planets. Its symmetrical rings give it a matchless grace and there is nothing like them anywhere else in the solar system. Constructed and placed in orbit by the Elders, millenniums ago, they give the people of Saturn complete mastery over the forces of gravity on their planet. Thus, all work is done by perpetual motion and men can fly above their world in great machines tuned to the frequency of the rings. Freed from manual labor, the men of Saturn have developed great wisdom and the wisest among them is Xodiac. It is said of him that he can tune his staff to play upon the great rings; the music of the spheres resounding throughout the universe to be heard by wise men everywhere.
