Hacker’s plan to clone himself — so he can wreak havoc throughout Cyberspace in many places at once — goes haywire when his newly invented Clonitron clones Delete instead of himself. But Hacker takes advantage of the mishap by sending the Delete clones to take over the R-Fair City cybersite. To complicate matters, every time Delete sneezes his clones multiply even more.
