van Arnam, Dave & Archer, Ron - Lost In Space (1967, Pyramid)

"YOU CANNOT ESCAPE, EARTHMAN" Curiously, Smith tried on the mysterious, silvery helmet he had discovered in the workshops of the deserted planet-then, in horror, he turned to face the charge of a giant, rat-faced alien space raider.
Desperately, Smith cried "Stop"-and, amazed, he saw the alien halt, glaring. "What-why are you standing like that?" he asked.
"You told me to stop. I cannot move," the alien snarled.
Then Smith realized . . . the "helmet" harnessed the incredible mental powers of a forgotten civilization. It had saved his life-and it would do still more for him....
"Power," he whispered. "Power . . . to rule the Universe!"
