Plot
M.A.R.S.'s real name is Axos, he is from the planet Omnicron and was one of the ten M.A.R.S. soldiers of the planet. For many years the Omnicronians where at war with a race of aliens known as Red Spartans. The Red Spartan males are large beasts who live only to kill while the females are very intelligent but are extremely sadistic. The only member of the males who has some form of intelligence is the king, Phanatos, though he is more or less a barbarian warlord, while the queen, Eridite, is a cold calculating monarch who thinks bathing in the blood of people younger than her will keep her young forever. The Omnicron are usually peaceful, but if they are invaded they do fight back, and because of this the war began. The Omnicron managed to fight off the Spartans, who fled to another planet. The ruler of the Omnicrons sent Axos to chase after the Spartans, to make sure no other planet will have to face their wrath.
