Kiyotaka and Yaiba were the Messiah and Anti Christ

 * The imagery is laid out in story, and both take the nickname "God" at times. While they're abilities are astonishing, they mostly revolve around Awesomeness By Analysis and Xanatos Roulette. However, their feats could alternatively be driven by divine intervention, and Yaiba at least breaks science by making eugenics, which is disproven in-story, actually work. All of his offspring also go mad at the same age, as did he, which is Lampshaded as being scientifically improbable, and his line is considered 'cursed'.
