Zigi and Zagi
A pair of likable , albeit somewhat rambunctious, young brothers, Zigi has honey-blond hair, Zagi's is black, who live with their father, mother, and their lovely dark-haired sister Zyra (Act No. 316, Sep 1964: "Zigi and Zagi's Trap for Superman!") in Centauri City, "on a Planet in the Alpha Centauri System," 23,342,816,000,000 Miles from Earth.
Although the texts describe them as “mischievous imps†(Act No. 315, Aug 1964: “The Juvenile Delinquents from Space!â€) and “conniving scamps†(Act No. 316, Sep 1964: “Zigi and Zagi’s Trap for Super man!â€), they are actually well-meaning, if fun-loving, youngsters who, arriving on Earth from their home planet—which is described as “far more scientifically advanced than Earthâ€â€”in August 1964, unintentionally wreak havoc because of their “weird scientific powers†and lack of familiarity with earthmen’s ways (Act No. 315: “The Juvenile Delinquents from Space!â€). Even Superman, who is driven frantic by their antics, comes to think of them fondly as “two of the nicest kids I’ve ever met!†(Act No. 316, Sep 1964: “Zigi and Zagi’s Trap for Superman!â€). (TGSB)
