Anahita

Anahita (d. April 15th, 2008), also known as Aredvi Sura Anahita and the Iranian goddess of fertility, health, water, wisdom, and war, is a female theta and the only known female member of the Djinn. Originally from the Djinn Homeworld in the Perseus arm of the Milky Way Galaxy, she and the other eleven members of the Djinn, including her brothers Ahura Mazda and Mithra and nephew (through Ahura Mazda) Atar, crash landed on Earth over six thousand years ago. Stranded, they quickly became infected by the same virus that gave humans their secondary genders/designations. But they were given more side effects from the virus than just the designations, as they all gained powers and experienced extremely slow aging.
Because of how they were infected, most of the Djinn, as they would much later be called, knew and agreed they could never return to their home world. The only one of the group that disagreed was Angra Mainyu, who was killed by the others in order to prevent him from going back to their planet and spreading the virus to the rest of their kind. After that, the remaining members of the Djinn because of their powers and long lives eventually became known as the Iranian deities and, in the case of the others besides Ahura Mazda, various aspects of him in Zoroastrianism. They protected people in regions from Anatolia (modern-day Turkey) and Pakistan.
At some point several centuries ago, after the rest of the Djinn had already died, Anahita was captured by the leader of the real Ten Rings. Held captive by him for centuries using a pair of handcuffs that repressed most of her powers save for a few specifically related to her aspect of fertility, she was eventually taken by another group who also decided to use the Ten Rings moniker. This group would eventually become known as Zadran's Ten Rings.
In 2008, when Tony Stark was captured by Zadran's Ten Rings, she was the one to save him from certain death by putting the electromagnet inside his chest to prevent the bomb shrapnel from entering his heart. Held captive in the same room as him, she helped him with the first Iron Man suit. When Tony went into heat because of her powers that were not repressed by the cuffs, unable to use her powers to stop his heat without him becoming pregnant, she fixed his tubal ligation and other reproductive issues and they shared his heat together, resulting in him becoming pregnant. Because of this, Anahita then gave him her bangle, a piece of jewelry from her and the rest of the Djinns' home world.
Anahita was fatally wounded on April 15th, 2008, when Tony donned the first Iron Man suit in order for them to escape from Zadran's Ten Rings. Before she died, she revealed to Tony that their child together would be the last of the Djinn, due to the others having already died.
