Soma

the long version

The generic trap had condemned Aton-Five to a tortured existence. Half standard human and half mutant descendant of the forbidden Minionettes, to whom hatred and sexual cruelty were the very breath of life, Aton fought against his own instincts to win a place for himself among normal humankind. Yet both more and less than human, he fell easy prey to an unseen foe. Imprisoned on Chthon, the world he mistakenly thought he'd freed permanently from its reign of terror, Aton was forced by his captors into a training program calculated to turn him into the ultimate tool of unreasoning destruction. But even his tyrannical master didn't understand just how deadly a weapon Aton was becoming. For they themselves were enslaved by a higher power, an intelligence sworn to transform Aton into the betrayer of all living things!
