Star Quest
Dean Koontz
 "In a universe that had been ravaged by a thousand years of interplanetary warfare between the star-shattering Romaghins and the equally voracious Setessins, there seemed now but one thing that might bring the destruction to an end. That would be the right catalyst in the hands of the right people. The right catalyst could well be the individualist rebel, Tohm... he who had once been a simple peasant and who had been forcibly changed into a fearfully armored instrument of mechanical warfare—the man-tank Jumbo Ten. But the right people? Could they possibly be the hated driftwood of biological warfare—those monsters of a cosmic no-man's land—the Muties?" ro:Star Quest
