Stories
- The Traitorous Challenger · 10 pages
A prospector uncovers a monster, an indestructible one-eyed walking box that tramples villages. The Challengers's weapons don't make a dent. And June mysteriously sabotages their efforts! Prof finally guesses the monster's one eye is solar-powered. Pursued until sunset, the monster expires. June had run a computer program that predicted the Challengers would die, hence her sabotage. But her efforts changed the equation, so she saved the day!

Finally Ace uses spinning circles to hypnotize and capture Roc.
