Seven decades ago in the year 208C, or 2108AD for earthlings, a race of highly intelligent beings built the ultimate doomsday device to protect their planet. The device was named Xardion. The artificially intelligent being was built on the planet Fiera, the fire planet of the Alpha-1 solar system. On Fiera science had long since evolved into a state of super theory. The planetery science community discovered that a depletion of the ozone layer would cause a drastic change on the planet in the future and it would end up unlivable in approximately 285 years.
Meanwhile at the other end of the galaxy, a professor, Dr. Sim U. Late was working on his theory of life and surroundings. His goal was to rejuvenate a single planet and built an artificial eco-system. Once his theory and planet were complete, he left one human on the planet to test his project "New Frontier". His goal was to control the eco-system and enable the people of Fiera to relocate on a safe planet when the time came.
Unforutnately the doctor became ill and in anticipation of his death he programmed NGC-1611 super computers to control all functions of the ecologym including its defense. The super computers malfunctioned 12 years later and the sole inhabitant of the planet was left to a survivalistic lifestyle. The guardian devices tried to protect the test human and eco system. The computers misinterpreted their instuctions as "search and destroy". Without the computers control over the guardians they soon became beasts of rage and fury, transforming many times beyond their original design.
During this time the distant Alpha 1 Solar System was locked in a 7 month war. In an act of desperation, the leaders of the three planets quickly resolved their differences to fight the NGC-1611 invaders by utilizing their three most signifigant robotic eliminators. Immediately "Triton:King of the Sea" was commisioned by the oceansphere, Aquata. The Hollowsphere, Zikar sent Panthera the cybernetic leopard and Fiera sent Alcedes the telekinetic Beastybot. Each of these robots must arm themselves with weapons located on the surface of the planets.
The robots are role progressive, or learning mechanisms. The more experience they have, the better their ability to carry out the desired task. You duty as given by the planetary federation is to lead the pilots of Alcedes and Triton and the cybercerebral mind of Panthera to the distand star NGC-1161. Locate Xardion if possible, but any cost you must terminate the invaders power source. Save the Alpha 1 Star System!
