AMAZONA the MIGHTY WOMAN - The 9th Wonder of the World!

https://pdsh.fandom.com/wiki/Mighty_Woman

In the vast cold reaches of Hyperborea lives AMAZONA - a woman of surpassing strength and unmatched beauty. She and her people are the last survivors of a super race that perished during the period of the last ice age in an event simply known as The Hyper War - a global and even interplanetary conflict that nearly wiped out humanity and caused the fall of Atlantis as well as Oz's isolationism!

When she meets Blake Manners - a handsome explorer who accidentally stumbled upon their citadel after being the lone survivor of an ill-fated expedition, she becomes infatuated with him and follows him back to America. In America, she's given the name MIGHTY WOMAN - The 9th Wonder of the World! and in the process becomes Vixen's modern day Wonder Woman analogue (despite predating her by over a year-and-a-half in our world), with semi-retired D.O.J. member and diplomat, Princess Clare Lune aka https://pdsh.fandom.com/wiki/Moon_Girl being the Golden Age equivalent!
