"And crush us all out," conceded Bud dolefully, "like a bad kid stamping out an ant-heap. That's all we are to him. Just so many ants. No, there's only one way left. The Flight Leader has decided we've got to use ourselves as human shells, Rocky. Bullets won't harm him, but if we can smash these ships into some vulnerable spot ... his eyes ... perhaps we can kill him before we ... we...." "_Wait!_" cried Rocky. "_Ants! That's it!_ Not _ants_--but _Antaeus_! Bud, listen carefully! Those craft are equipped with repulsor beams?" "Why--why, yes, but--" "Then contact your Flight Leader immediately. Tell him these are orders. As an S.I.D. agent it is your privilege to take over any command in case of urgency. I want the three ships of your flight to turn on their repulsor beams to maximum strength--and bear down on the Colossus!" "B--but, Rocky--" "Do as I say!" "Y--yeah, sure. But if they don't lift him?" "Don't be an ass! Repulsors are used to move asteroids from trade-lanes, aren't they? Colossus is huge, but no bigger than thousands of asteroids! They'll lift him off the face of this world!" "And--and then?" "Then we shall see," said Rocky grimly, "if I have saved us, or just given us a few minutes' grace. If I'm wrong, he'll fight his way free as soon as the repulsors wear down. But if I'm right--" "Well?" "I've got to be right! And now--get going!" "Y--yessir!" gulped Bud obediently, and disconnected to contact the Flight Commander of the spacevessels. Thus it was that a few moments later, as Rocky and Gunner lay in their pit watching hopefully, as the unceasing throngs continued to block the safeway, casting fearful looks back over their shoulders as they fled from one doomed place to another, that the five ships gathered together momentarily ... then separated ... then converged on the Colossus in a narrow V--their prows invisibly pouring repulsor radiation at the gigantic creature. The reaction of Colossus was the only thing which assured Rocky his plan was being carried out. For the repulsor radiation was colorless. But as the ships neared Colossus, he bent, momentarily, at the middle as if he had suffered a surprise thrust in the belly or groin. Then an expression of anger crossed his features. [Illustration: _Anger filled Colossus' face; he flailed with both arms._] The ships were coming in beneath the protection of a cloud-bank, but Colossus spotted them. He flailed a whiplike arm at them as a pettish child might sweep at bothersome flies ... but to no avail. The speedy craft swirled away, but kept their prows pointed at his midriff. Again Colossus struck at them, and smashed one. Then a new idea struck him. Reaching above his head, by sheer force he tugged from a satellitic course about Titan a rogue rock of tremendous size. A rock which must have been every bit of fifteen hundred feet in diameter, a shard of matter hewn into a perfect sphere by long ages in the Rings of Saturn.
