What could be the possible reasons for Tony Stark to neglect his daughter in the fanfiction?

Maybe he's too caught up in his work. Tony Stark is often depicted as a workaholic, so he could be so focused on his inventions and saving the world that he simply doesn't have time for his son.

Maybe his own self - centered nature plays a role. Tony Stark has always been a bit of a playboy and a genius focused on his own projects. His daughter might seem like an afterthought compared to his latest invention or business deal.

Maybe he doesn't fully understand his powers yet. Tony Stark is a scientific genius, but new powers might be beyond his current understanding. He could be worried that if he reveals them too soon, he won't be able to control them properly and might cause harm. So, he chooses to hide them while he studies and figures them out.

One possible plot could be that the daughter discovers some dark secret about Tony's past, like his involvement in a project that had negative consequences for her mother. This revelation makes her angry and she decides to oppose him. She might team up with other villains who also have a grudge against Tony.

In fanfiction, she might run away because of a misunderstanding. Maybe she overheard something she wasn't supposed to and misinterpreted it. For example, if she heard her father talking about some kind of protection plan for her that she thought was him trying to control her life more. It could also be that she has her own secrets, like developing powers that she's afraid to tell her father about and decides to run away to figure things out on her own.

Guilt. For example, if he fails to save someone he cares about. He'll feel responsible and that could lead to him crying.

In fanfiction, emotional distress can also be a factor. If something really bad happens, like the loss of a loved one or the destruction of his work that he has put so much effort into, the shock and grief could be so overwhelming that he faints. Additionally, he could be suffering from some hidden illness that flares up suddenly and causes him to faint.

One possible reason could be that Shield has been corrupted from within. Maybe Tony discovers some dark secrets or unethical practices within Shield that make him believe it's a threat that needs to be eliminated. For example, if Shield was involved in illegal human experimentation or was secretly working with enemies of the state.

One possible reason could be that Tony Stark is being overly critical of Peter's superhero work. Maybe Peter made a big mistake during a mission, and Tony's harsh words in his attempt to correct Peter made him cry. For example, if Peter accidentally put civilians in danger and Tony scolded him severely.

Well, she might run away because she feels overshadowed by her father's fame. Everyone always talks about Tony Stark, Iron Man, and she may feel like she's just an afterthought. Maybe she wants to find her own identity away from the Stark name.
