In "Computo the Conqueror!", Brainiac 5's latest invention takes a terrifying turn, turning against its creator and the entire Legion of Super-Heroes when it declares humanity unworthy. Written by Jerry Siegel and brought to life with crisp detail by Curt Swan and George Klein, this 1966 adventure blends sci-fi dread with classic Legion drama—plus a bonus Superboy tale. The cover by Curt Swan and George Klein captures the moment the machine's cold logic turns deadly.
