Harlan Ellison’s Run for the Stars

The Kyben demolished Deald's World and their armada was heading for the Earth. All that stood in their way was a man on Deald's World named Benno Tallant, about as lousy a candidate for hero as one could imagine: junkie, looter, coward, betrayer. So the retreating Earth forces made him the last man on Deald's World. They surgically implanted a cataclysmic bomb in his body, turned him loose, and let the Kyben hunt him down. SEE BENNO RUN. RUN, BENNO, RUN LIKE HELL.
