Y/N is Tony starks daughter, from before he met pepper. She was twenty when he died saving the world from thanos. Y/N took over stark tower along with most of his company. She works in his lab the same way he did, sharing his intellect and sarcasm. She knows all of the avengers and S.H.I.E.L.D. Agents. Often throwing galas and parties. She’s constantly working on a new project, getting little to no sleep. After Tony’s death, she just became him. She tries to be around for Morgan but she’s usually consumed in her work, and the parties and pretending her life didn’t get flipped upside down. She’s now twenty-three and living his legacy.
