Tony Stark

Tony Stark (legal name: Anthony Edward Stark) (b. May 29th, 1980), otherwise known as Iron Man, is the son of Howard and Maria (née Carbonell) Stark, the husband of Bruce Wayne, the omither of Dick Grayson (adopted), Jason Todd (adopted), Lili Wayne, Harley Stark, Peter Stark, Bea Wayne, twins Edward Wayne and Gemma Wayne, and Kamala Stark, and the stepomither of Damian Wayne. He is currently the CEO of Stark Industries.
Born on May 29th, 1980, Tony was the biological son of an unnamed man and Maria Stark, however he was raised by Howard. Howard is implied to have had had involvement in his conception, though the entire set of circumstances is currently unknown. As a child, instead of his mother and Howard, Tony was closer to Ana and Edwin Jarvis, who he viewed as his honorary parents.
Tony presented as an omega in the fall of 1994 at the age of 14. He was subsequently betrothed to his future husband, Bruce, by Howard in February of 1995. The two would eventually become close and enter a romantic relationship, although this had not been Bruce's intention: intentionally, he had been fine with their marriage being a front for Tony's protection. Tony also quickly discovered that Bruce was Batman during their courtship, although he agreed on the necessity of keeping it a secret.
Bruce and Tony were married on May 29th, 1997, Tony's seventeenth birthday, while Tony was a student at the Massachusetts Institute of Technology. He later received his BA (1999) and PhD (2012) degrees in Physics and Engineering from there. Before December of 2001, the two had four children together: Richard 'Dick' John Grayson (b. March 21st, 1990), who was adopted by them after his biological parents were killed by Red Hood, and biological children Lilibeth 'Lili' Mariane Wayne (b. February 1st, 1998), Harley James Stark (b. July 23rd, 1999), and Peter Benjamin Stark (b. August 11th, 2001).
In December of 2001, Tony's parents and Ana were killed by the Winter Soldier, as was revealed to him and Bruce by Phil Coulson. Bruce then went on a mission to track down the Winter Soldier, which led to him discovering that she was Bucky Barnes, the alpha wife of Steve Rogers, and a captive of HYDRA's alongside Jason Peter Todd (b. August 18th, 1993). During his quest to rescue them, Bruce was killed by HYDRA agents, resulting in his and Tony's bond being severed. But he was soon revived by Bucky using a Lazarus Pit near the HYDRA base, resulting in their bond being restored. Bruce then took Jason and Bucky back with him to the Glass House in Gotham, and Jason was adopted by Tony and Bruce. Bucky was eventually accepted into the family as well, despite what HYDRA had forced her to do.
Because of Howard's death, Tony ascended to the role of CEO as Stark Industries. He and Bruce went on to have three more biological children: Beatrix 'Bea' Katherine Wayne (b. November 12th, 2003) and twins Edward Thomas Wayne and Gemina 'Gemma' Louise Wayne (b. May 9th, 2007). They also adopted a cat, Alfred the Cat, after the events involving the Joker, formerly known as Red Hood, Harvey Dent, and Rachel Dawes, since the cat had previously been hers. His honorary niece, Riri Rhodes, daughter of his best friends Rhodey and Pepper Potts was born around the same time as his twins' as well. And of course, Tony completed the work on his bots, Dum-E, Butterfingers, and U, and his artificial AI, JARVIS.
As CEO, Tony worked closely with his godfather and COO of Stark Industries, Obadiah Stane. Over time, despite Tony's dislike of him, Obadiah was able to earn his trust. In 2007, when both Tony and Pepper were pregnant, he was able to recommend Farzana Zadran to become Tony's internet. It is partially because of her that Tony later visited Afghanistan, as she encouraged him to go, although he had his own motivations as well.
On February 8th, 2008, during his trip to Afghanistan, Tony was captured by Zadran's Ten Rings. While he was in the process of being captured, a Stark Industries missile exploded right next to him, causing the injuries he experienced in canon. He was only saved by his fellow captive, Anahita, who put an electromagnet in his chest to keep the shrapnel that she could not remove from reaching his heart.
While in captivity under the Ten Rings and building the suit that he would become known for, Tony went into heat several months earlier than he was meant to. It was revealed by Anahita that she was the cause, as she was actually Aredvi Sura Anahita, the Iranian goddess of fertility, health, water, wisdom, and war. Out of an agreement to end his heat, since she could not stop it due to the handcuffs that were straining her powers, she fixed Tony's tubal ligation and the other reproductive issues he'd developed. The two then shared his heat, with the result that he became pregnant with her child.
Tony was able to escape the Ten Rings on April 15th, 2008, although Anahita died in the process. Before she did, she told him that their child would now be the last of her kind, the Djinn. After wandering in the desert for two days and nights, Tony was then rescued by Rhodey and the US military on April 17th, 2008, and reunited with Bruce.
From there, the events of Iron Man mostly happened the same as in canon, including the death of Stane, as did the events of Iron Man 2, albeit at a much quicker pace than in canon. Tony witnessed the birth of his and Bruce's first (adoptive) grandchild, Mari Grayson, before he gave birth himself, as Dick had gotten pregnant by Zatanna Zatara before she had left Gotham in the December of 2007. Kamala Aredvi Khan Stark (b. December 23rd, 2008) was born a few months later and was adopted by Bruce at birth. Six days later, Damian Hafid al Ghul Wayne, Tony's stepson, the son of Bruce and Talia al Ghul as the result of her raping him, was born.
Tony resigned as the CEO of Stark Industries in January of 2009 during the same speech in which he revealed himself as Iron Man to the world. His successor as CEO was Pepper.
