Within a short period of time, twin threats personifying the ultimate representation feminine "perfection" became a sore spot in the side of superheroes on twin worlds. On Earth-One, the "Fiend with Five Faces" nearly conquered that planet before the Justice League turned the tides on the ancient adversaries, as did the Justice Society versus the Four Kings from eons ago. And yet, one among the number of Fiends...Mauri... escaped the League and with her enchanting allure enlisted a private army of minions to attack her superheroic adversaries, attempting to eliminate this threat. On Earth-Two, Mauri's cosmic twin Osira similarly awoke from a long slumber and as like that sinister siren Osira used her own allure to enlist armies of males as well. In both cases, the Wonder Women ended up battling these lethal ladies and the Amazing Amazons' own teammates now doing their foes' bidding. Both women were heartsick to lose the ones they most held dear, for Mauri this was her fellow four kings and for Osira it was her mate from centuries past, Hefnakhti. His Earth-One counterpart was another space traveler named Sphinx who later battled them Dial "H" for Heroes kids.
Shortly after Mauri and Osira reappeared among humanity after thousands of years of sleep, these femme fatales had ensnared the Greatest Heroes of their new worlds and sent them out to attack the Wonder Women. On Earth-One, Princess Diana had the aid of her allies Black Canary and Supergirl, though neither existed as yet on Earth-Two to aid their Diana. Nevertheless, but Maidens of Might dealt with the terrible triads of Batman, Elongated Man and Aquaman as well as Mister Terrific, the Atom and Starman. As for Mauri, after she was defeated she was imprisoned alongside the other four fiends from of old, while Osira left her new world behind realizing without the now deceased she could no longer find peace as a ruler.
