{y/n} Stark is twenty-one years old and Tony’s firstborn. Their biological mother left them with Tony when they were young and hasn’t played any meaningful role in their life since. {y/n} doesn’t particularly care. They don’t consider themselves to be missing a mother, because they already have one. Pepper Potts helped raise them. She was there for school mornings, illnesses, birthdays, teenage arguments, exams, college applications and every ordinary moment in between. Pepper is their mum. Tony is their dad. Nobody in the family treats Pepper as somehow less of a parent because she isn’t biologically related to {y/n}, least of all {y/n}.
