Y/n Stark is the 16 year old daughter of Tony and Pepper. She blipped in the fight against Thanos. 5 years later, her and everyone else are back, but the fight isn’t over. Y/n sees an opportunity to save everyone, meaning that she sacrificed herself. At her funeral though, she’s there. She’s not alive, but not entirely dead either. She’s some sort of ghost, and only her dad can see her.
