23rd century (Earth-715)
Toward the end of the twentieth century in one alternate timeline, worldwide chemical and biological warfare broke out, resulting in the sterilization of 95% of the Earth's female population. The fertile 5% seized political power and began a systematized program of oppression against men, who were seen as having nearly exterminated the species. By the early 23rd century, natural childbirth was totally supplanted by laboratory birthing, and men were bred only as servants, entertainers, and breeding stock. The major concerns of the United Sisterhood Republic, one of the leading nations of the new world, were exterminating the renegade bands of roving free men and preventing incursions from foreign nations and powers.
Thundra was born in the Central Birthing Center of Greater Miago (Milwaukee-Chicago), a government-run laboratory where fetuses are brought to term in artificial wombs. Genetically engineered for strength and endurance, Thundra was sent to military school when she was eight years old. By the age of eighteen, she had distinguished herself as the finest warrior in the Midwestern Republic and became an officer in the militia. She led assaults against roving bands of renegades and the armies of the Central American Empire.
In the middle of Thundra's military career, Russia faced an invasion from soldiers from another alternate timeline, a world known as Machus. Men from this alternate Earth had managed to overthrow their female oppressors generations previously, and used their technology for inter-dimensional travel to journey to Thundra's Earth to liberate the men of that world. In an attempt to strike back at the men of Machus, Thundra stole their dimensional apparatus, planning to launch a counter-attack on their world. The machine malfunctioned, however, and displaced her to the twentieth century. Afterafter acclimating herself, she decided to humble the strongest man on Earth, thereby, she believed, preventing the world of Machus from ever coming about.
Modern Era (Earth-616)
Upon her arrival, she was befriended by the criminal The Wizard, of the Frightful Four, whose instruments detected Thundra's time displacement. The Wizard was looking for a replacement for Medusa, and saw Thundra as an ideal choice. Thundra pretended to go along with the Wizard's plans in order to exploit his resources. She determined that the Thing of the Fantastic Four would be the ideal object lesson to vanquish in battle. Alongside the Frightful Four, she engaged the Thing in a battle, besting him fairly on at least one occasion. Recognizing that her actions in the past would have little bearing on the future, she betrayed the Frightful Four to become an ally of the Fantastic Four.
Thundra tried to help the Thing when he was mind switched with the Hulk but was knocked out in the process, however when she awoke she returned the blow that the "Thing" delivered to her earlier before walking off.
Mahkizmo, the greatest warrior of Machus, eventually trailed Thundra to the twentieth century and took her back to her own time to stand trial for her theft of the interdimensional travel equipment. The Fantastic Four followed Thundra (using their own means of travel) and helped Thundra battle against the dimensional invaders of Machus. Before leaving the future for their own time, the Fantastic Four destroyed the mind-domination equipment of Machus and hoped that the two worlds would settle their differences amicably. Thundra returned to the twentieth century with them, believing that her world would be changed unfavorably by the presence of the extradimensional men.
Some time later, Thundra was contacted by the Nth Command, subsidiary of the Roxxon Oil Company devoted to extradimensional research. They told her that a divergent future world existed which was never invaded by Machus. She agreed to carry out a mission for them in exchange for being restored to her world. The mission was leading a band of female Roxxon operatives called the Grapplers into the government energy facility Project: Pegasus in order to sabotage it. She was apprehended in the process but was released so the authorities could track down the party that sent her. She briefly became an ally of Hyperion of the Squadron Sinister, another Roxxon operative.
When she learned of the Nth Command's sinister motives, she stole one of the Nth Projectors, dimensional aperture synthesizers. Creating a portal to her own time, she went through it after bidding a fond farewell to the Thing, the twentieth-century male she had most learned to admire. Hyperion attempted to follow her, but the portal closed while he was halfway through, stranding him in limbo. Thundra arrived in her new reality safely.
United Sisterhood Empire
Thundra became the ruler of the United Sisterhood that existed in this alternate future and eventually found herself at war with the extradimensional kingdom Polemachus and its chauvinistic warrior monarch, Arkon. Towards the end of their long, bitter conflict, Thundra employed the hero teams Avengers and Fantastic Four as pawns in her war with Arkon. However, the heroes helped Thundra and Arkon discover that they shared a strong mutual attraction, an attraction that ended their conflict when they became lovers. Afterwards, Thundra joined Arkon in Polemachus as his consort.
Some months later, Thundra and Arkon sought the Avengers' aid in repairing Polemachus' energy ring and protecting the maiden Astra from becoming a human sacrifice to Polemachus' religious zealots led by the high priest Anskar.
Arkon also had a rival in his Grand Vizier, who, over time, convinced Arkon to return Polemachus to a more barbaric lifestyle rather than rely on its science. The Grand Vizier then abducted the superhero and Avenger Photon along with the super-villains battling her at the time, the Wrecking Crew. The Grand Vizier used the Wrecking Crew to depose of Arkon and Thundra, until the Avengers arrived to rescue their teammate and restore Arkon to the throne. Polemachus returned to its hybrid barbaric/scientific lifestyles.
Dealing with Hulks
Eventually, Thundra returned to the United Sisterhood Empire. However, knowing that she couldn't lead forever, she began devising a plan to have worthy offspring to one day take her spot leading the fight against men. She announced to her warriors that she was going back in time to challenge the incredible Hulk, the strongest man of all time, but, in reality, Thundra was planning to get some DNA samples, so she could have his child. During their fight, she scrapped the inside of Hulk's cheek and took some cell samples that would hopefully be enough for the artificial insemination.
When she tried to get back to the Empire, the time machine malfunctioned and she was stranded in the present. During this time, she joined She-Hulk's Lady Liberators in a fight against Red Hulk. They managed to defeat him, but, while waiting for him to revert to his human form, he regained his strength and broke free, kidnapping Thundra in the process. When he got to a safe location, he revealed he knew of her story and wanted to start a partnership.
The two fought alongside each other on many occasions, before Thundra finally managed to find a working time machine. Before departing to her time, Thundra kissed Red Hulk passionately, leaving him to hope, in vain, that she had actually taken some of his cells too.
Superhuman Condition: Thundra possesses a number of powers that are the result of genetic engineering such as:
- Superhuman Strength: Thundra is superhumanly strong. She possesses sufficient strength to lift approximately 60 tons. Furthermore, this strength also extends to her legs, enabling her to leap 45 feet.
- Superhuman Durability: Thundra's body is more resistant to injury than that of an ordinary human. Her great skin density gives her a hardness of 7.5 on the Mohs hardness scale, enabling her to resist the penetration of small caliber bullets.
- Peak Human Speed: Thundra is capable of running at speeds of 32 miles per hour.
- Peak Human Stamina: Thundra is able to exert herself at peak levels for about 50 minutes before accumulated fatigue-poisons in her bloodstream force her to reduce her activity or rest.
Skilled Combatant: Thundra has been extensively trained in boxing, wrestling, and the military arts of her century. She is experienced in the use of the broadsword. Thundra is a seasoned combat veteran of many anti-renegade raids. She had little experience with fire-arms because of their virtual elimination in her own time.
Thundra commonly uses a chain as a weapon.
