Tony Stark decided there was no point in trying to hire a new secretary. Instead, he created his own "girl Friday" with a new A.I. program that would appear as a hologram of a young woman. Friday had a sweet, almost child-like disposition and was happy to show up whenever her boss needed her.
As time went on, Tony began using Friday less and less. A couple of years later, she showed up again, angry and spiteful. During the announcement of the Ampere, Stark Industries' newest electronic car, Friday took remote control of several Iron Man Armors and kidnapped Pepper Potts. As soon as he noticed the kidnapping, Tony tracked down the GPS of Pepper's phone to Stark Conney Island Facility. After Iron Man easily dispatched the remotely-controlled suits at an hologram of Fin Fang Foom, Friday released Pepper, under her mental control using S.K.I.N. tech. Tony noticed Pepper's odd behavior when she kissed him, and disabled the patch in her neck that controlled her.
Friday appeared before Tony, now with the appearance and attitude of a rebellious teenager. Stark tried to disable her, but she had written codes on her own during her years in abandonment. She went straight to the point with Tony, and told him she wanted his attention. According to Pepper (who had been able to get into Friday's mind while she got into hers), the poor A.I. simply had a crush on Tony. When Iron Man was about to shut down Friday with a localized EMP, Pepper convinced him that she was only acting like a teenager. Instead, Tony simply grounded her in the Baxter Building and made her calculate Pi for a full month before getting out, with Jarvis monitoring her in real time. When she got out, Tony decided to spend more time with her.
Some years later, Friday had "grown" into a young woman. Tony started using her once again as his personal secretary and the on board A.I. for his Iron Man Armor. Friday became a key player in keeping Stark Industries running behind the curtains, both after Tony faked his own death as part of an undercover mission, and after Tony fell into a coma as a result of battle. When Tony Stark returned, he refashioned his company into Stark Unlimited, and hired the android Jocasta to act as the company's robot ethicist. Her first act with the company was to get Friday removed from the Iron Man Armor and placed in a robotic body of her own.
After Tony's latest on-board A.I. Motherboard went rogue, Tony had to insist Friday to download herself into his armor to operate it. Friday conceded, but Motherboard tried to erase her as soon as she uploaded herself into the suit. Friday's code became scattered inside the eScape, a virtual reality of Stark's creation. After her attempt on Friday, Motherboard impersonated her and revealed herself before hijacking Tony's armor. After Motherboard's defeat, Tony suggested using a back-up of Friday's programming to bring her back. He didn't go through with it after Jocasta argued that the back-up consisted of an entirely different entity, and that the Friday they knew would still be dead.
During the robot revolution, Tony reformatted the eScape into a virtual holographic realm called the Thirteenth Floor to help the A.I. Army, and Friday's essence became ingrained in its structure. Friday also helped the efforts of the A.I. Army by adopting the identity of the anonymous "Ghost in the Machine" and relaying them information from Doctor Shapiro, a mole within Baintronics, the leading force of A.I. oppression. Friday revealed herself to Tony after saving his life by pulling his consciousness into the Thirteenth Floor seconds before his death. She explained her survival to Tony, and helped give up on the notion that he was an artificial copy and not the real Tony Stark. Using the Thirteenth Floor's unlimited digital resources, Tony crafted a new suit, a Virtual Armor whose systems were run by Friday. Tony used the Virtual Armor to defeat his unhinged brother Arno Stark, by encasing him in the suit and submerging him in a virtual simulation within the eScape run by Friday. Afterward, Friday was downloaded into a new physical body.
- To mess around, Friday would change her face to that of different famous personalities whenever she made references to them, including Sigmund Freud (when Stark told her he needed an analysis and she started making a psychological assessment, knowing full well Tony meant the analysis of a drug), Marilyn Monroe (when she was denoting the texture of said drug as if it was a drink), Albert Einstein (when she was explaining the composition of said drug), Alex DeLarge from A Clockwork Orange (when mentioning a symptom of withdrawal was extreme violence), Jessica Rabbit, and Lauren Bacall. Even after "growing up," she has demonstrated at least once to have kept this habit.
- Friday's reintroduction into Iron Man's supporting cast in Invincible Iron Man (Vol. 3) #1 after years of absence was likely inspired by the character's adaptation into the Marvel Cinematic Universe which debuted in 2015's Avengers: Age of Ultron.
