In "Justice Society of America" (vol. 3), a new Starman appears wearing a costume identical to that of the Starman from the "Kingdom Come" series. It is soon revealed that this individual is indeed the Starman from "Kingdom Come", and that he is also Thom Kallor, a native of the planet Xanthu and member of the Legion of Super-Heroes in the 30th and 31st centuries. Due to a time-travel error, Starman traveled to Earth 22 before arriving in 21st-century New Earth.
