EARTH-715
"FEMIZONIA"

HISTORY: 
(Official Handbook of the Marvel Universe I#11: Thundra) - In the alternate reality of Earth-715, by the end of the 20^th century (see comments), chemical and biological warfare broke out, resulting in the sterilization of 95% of Earth's female population.

    The fertile 5% seized political power, and they began a systemized program of oppression against men, whom they saw as having nearly exterminated the species by causing war, poverty, hatred, violence, and pollution.

(Official Handbook of the Marvel Universe A to Z hardcover#13: Thundra) - Women genetically enhanced themselves to become equal to men, and men strengthened themselves via radiation treatments.

    That radiation had the side effect of sterilizing the children they subsequently conceived, and it became impossible for men and women to reproduce sexually.

    By the end of the 22^nd century, society had split formally into two camps, men and women, and cataclysmic wars had occurred between the sides. Each side developed its own methods of reproduction, men drawing on parthogenetic cloning, and women using genetically manipulated sperm samples held in their Temples of Genetics.

(Savage Tales#1/2 (fb) - BTS) - At the end of the 22^nd century (see comments), the Sisterhood took over Earth. Wishing to make certain that man would never rule again, the Sisterhood kept ten percent of the men as slaves to serve the needs of the Sisterhood, as well as to allow the continuation of the human race. 

(Official Handbook of the Marvel Universe I#11: Thundra) - Natural childbirth was totally supplanted by laboratory birthing, and men were bred only as servants, entertainers, and breeding stock. 

(Savage Tales#1/2 (fb) - BTS) - The remaining ninety percent of all the male children were abandoned in the wilderness...where they were left to perish. 

    However, not all of the males died. Most of those who remained grew strong -- and savage -- and more merciless, more brutal, than man had ever been before: The Beast-Men. 

    A smaller number of the male survivors remained civilized.

    The Sisterhood kept a supply of sperm in their Temple of Genetics, guarded by High Priestesses, which they used to maintain the population.

(Official Handbook of the Marvel Universe I#11: Thundra) - The major concerns of the Sisterhood, one of the leading nations of the world, were exterminating the renegade bands of roving free men (aka Beast-Men) and preventing incursions from foreign nations and powers.

(Savage Tales#1/2 (fb) - BTS) - At some point, Vega became Queen of the United Sisterhood Alliance (also known as the Femizons), and her sister, Lyra (born from the same sperm vial) became princess. 

(Savage Tales#1/2 (fb) - BTS) - Roving Beast-Men periodically assaulted the Sisterhood, apparently slaying some and carrying off others into the wilderness. The Sisterhood gradually tracked down the Beast-Men in their lairs and presumably slew those they found. 

(Savage Tales#1/2 (fb) - BTS) - Mogon of the Hills, a member of a civilized tribe of men sworn to restore the balance to society by destroying the Temple of Genetics and its sperm supply (presumably to force women to seek out relationships with men and eliminate the segregated societies), learned of the forbidden history-detailing brain tapes of Princess Lyra. Realizing that Lyra might be sympathetic to his cause, Mogon arranged to become Lyra's slave.

(Savage Tales#1/2) - As a reward for slaying another female warrior in combat as entertainment within Vega's court, Vega granted Lyra a handsome male slave (Mogon). 

(Savage Tales#1/2) - After learning more of the history of their world and of the civilized male society, Princess Lyra fell in love with Mogon and agreed to aid his tribe in order to restore a society where men and women could be togther. This had to be kept secret from the rest of society, which forbade treatment of men as anything other than possessions. 

    Syrani, the head of the Sisterhood's security police, had long suspected Lyra of not being fully loyal to the Sisterhood. She had her agents spy on Lyra, and when she went to meet with Mogon's rebel tribe, Syrani's police ambushed them. Mogon and Lyra slew the police squadron and then split up and fled back to the palace, each to their respective quarters. Lyra was called before Queen Vega, to face charges of highest treason, leveled by Syrani. Lyra contested the charges, but Syrani had her guards bring in Mogon, whom they had captured. Vega challenged Lyra to prove her loyalty by slaying Mogon. 

    Realizing that he was doomed and seeking to save Lyra's life both due to his love for her and the hope that she would find and aid other rebel tribes, Mogon goaded Lyra, taunting her as a weakling, while his eyes pleaded with her to slay him to vindicate herself. Lyra indeed skewered Mogon, killing him and resolving the charges leveled against her. 

    Lyra vowed never to forget Mogon, and she decided to seek out the other members of the tribe to find more men like him.

. (Fantastic Four I#151 (fb) / Official Handbook of the Marvel Universe A to Z hardcover#13: Thundra) - In the middle of Thundra's career, at the dawn of the 24th Century, the Sisterhood faced an invasion from an unexpected quarter. In the alternate timeline of Earth-74101 (aka Machus), contemporary to the Sisterhood's Earth-715, the world was ruled harshly by the male-dominated society of the Machans.     Under unrevealed circumstances, the timelines/dimensions of Machus and Femizonia began to grow closer together. Men of Machus had begun to travel over to Femizonia, and the men of Femizonia had begun to rebel. The Sisterhood was forced to use bloody and violent means in an effort to squelch the rebellion.     Nonetheless, the two worlds continued to move closer together, and the problems continued to worsen.

The Empress of Femizonia chose Thundra, their strongest warrior to travel back in time for two purposes: To humiliate Earth's greatest male, in hopes of altering time and preventing a world like Machus from arising (believing that men would learn their lesson for all time); and to collect genetic material from that male in order to create more powerful children. (Fantastic Four I#151 (fb) - BTS) - Thundra arrived in the modern era/heroic age of Earth-616, although some sort of temporal field surrounding the Baxter Building drew Thundra to the Thing (Ben Grimm), as opposed to the Hulk, Thor or other males stronger than the Thing. (Fantastic Four I#129-130, 133 - BTS) - Thundra battled the Thing, dominating the clashes, although various events prevented a conclusive victory. (Fantastic Four I#151-153 - BTS) - Mahkizmo, the nuclear-powered champion of Machus, was sent back to the modern era and kidnapped Thundra, transporting her to Machus where she was kept subdued by the will-deadening Domina-Ray.      The Fantastic Four (Human Torch/Johnny Storm, Medusa, Mister Fantastic/Reed Richards, Thing/Ben Grimm) traveled forward and across time in an effort to rescue Thundra but were also affected by the Domina-Ray and captured.      Immune to the ray due to her Inhuman nature, Medusa used the time machine to... (Fantastic Four I#153 (fb) - BTS) - ...Travel to Femizonia, and she brought multiple Sisterhood warriors back with her... (Fantastic Four I#153 - BTS) - ...To Machus, where -- despite also being affected by the Domina-Ray -- they distracted Mahkizmo sufficiently that the Human Torch was able to destroy the Domina-Ray. In the ensuing conflict, Mahkizmo summoned his nuclear-power but was smashed by Thundra and the Thing before he could unleash it.

. . The ensuing explosion both seemingly destroyed Mahkizmo and completed the merger of Femizonia and Machus into a new combined reality of Earth-7412, in which the Sisterhood and Machans co-existed.     Not belonging in this new world, the Fantastic Four were returned to the modern era of Earth-616, and Thundra was sent there as well. Medusa reasoned that the "natural forces" probably decided that Thundra belonged on a world where the sexes were equal by choice, not because two world were forced together. . (Marvel Two-In-One#67 - BTS) - Seeking to return to a world where Machus and Femizonia never merged, Thundra traveled to Earth-8009, in which the Sisterhood had conquered Machus.

COMMENTS: Created by Stan "the Man" Lee and "Jazzy" John Romita.
    In fact, Stan Lee owns the Femizons, and Marvel can't even refer to them by that name anymore. They are henceforth the Sisterhood.
    That obviously wasn't the case in Fantastic Four I#151-153, where they were consistently referred to as the Femizons, but the name Femizons most specifically refers to the generation from Savage Tales I#1.

    For the record, in Savage Tales, it is stated that "It was at the end of last century--when women first took over." Since that story took place in the 23rd Century, "last century" should refer to the 22nd century (2100s) or possibly the 21st century (2000s).
The OHotMU I#11 detailed the events that created the world of Femizonia, but named the date as the end of the 20th Century.

    Thundra has her own entry in the OHotMU I#11, Deluxe#13, Master Edition,#13 Alternate Universes 2005, A to Z hardcover#12 (2010). I didn't re-read all of her stories to do this profile, so please let me know if I missed a Femizonia/Earth-715 appearance, or any source issues for Thundra/Femizonia's origin.
    I am currently working on a profile on Thundra, but with all I have going on, it may take me quite a while to get through it.

    In Marvel Two-In-One#67 Thundra invited Hyperion (formerly of the Squadron Sinister) to come with her to Femizonia. He hesitated a second, and then jumped through the portal after her. The moment's hesitation caused him to be lost between the dimensions, until he was found by Master Menace in Squadron Supreme#7.

    A few years ago, I bought 3 issues of Savage Tales#1 for a total of $1.00...not a bad deal.

    This profile was completed 09/05/2025, but its publication was delayed as it was intended for the Appendix 25^th anniversary 's celebratory event.

Profile by Snood.

CLARIFICATIONS:
    So, for the record, here are the associated realities, all of which I plan to cover eventually
    And then we have to detail the variants; it all starts with:

• Earth-715 Femizonia prior to merge with Machus. Savage Tales #1 (1971)
• Earth-74101 Machus prior to merge with Femizonia. FF #151 (1974)
• Earth-7412 Merged Machus & Femizonia; men and women achieved peaceful interaction until Mahkizmo re-formed and brought Earth-616's She-Hulk there, which restored the natives' warrior natures; male/female relationships became violent, but still loving. FF #153 (1974)
• Earth-8009 Sisterhood ruled by Thundra; never merged with but rather conquered Machus; revolting Machans sent android against Sisterhood, android destroyed by Thing-616; warred against Arkon & men of Polemachus before romancing the same. Marvel Two-In-One #67 (1980)
• and then there's the Mahkos and Elysia dimension (Will-Killer, Sondia, Tambi) - alien world, realm to which Spider-Man and Starfox were briefly exiled by P.R.I.D.E., possesses warring factions of men of Mahkos and women of Elysia--Marvel Team-Up I#143
• I suspect there are other variants I haven't detailed yet...
