Another idea for this fanfiction could be that Tony Stark's daughter starts as a sort of 'Avengers - in - training'. She is constantly trying to prove herself to the established members. There could be a lot of action - packed scenes where she is in dangerous situations but manages to use her wits and any skills she has learned from her father to get out of them.
One popular type of fanfiction could be about Tony Stark's daughter joining the Avengers. Maybe she inherits his genius and creates her own high - tech suit. She might struggle at first to be accepted by the existing Avengers, like Iron Man did. But through her skills and determination, she gradually wins them over and becomes an important part of the team.
Maybe the story could be about her growing up in the shadow of her famous father. She struggles with the expectations of the world and the Avengers. But then she discovers a unique power within herself that has nothing to do with technology. With the help of the remaining Avengers, she learns to control this power and becomes a hero in her own right. For example, she might have a power related to energy manipulation that she initially fears but later embraces.
Well, she could have a mentor - mentee relationship with Bruce Banner. He could help her with the scientific aspects of her father's work. And she might be a bit scared of Hulk at first but then realize that he's just as much a part of the team as the others. With Hawkeye, she could learn about precision and focus in combat. Also, she could bring a new dynamic to the group, being the younger and more inexperienced one, but also having fresh ideas and a different perspective based on her unique upbringing as Tony Stark's daughter.
A plotline could be her trying to live up to her father's legacy. Since Tony Stark was such an iconic figure in the Avengers, his daughter might feel a great deal of pressure. She could start off making mistakes but then learn from them and become a better hero. For instance, she might accidentally set off a new weapon she was developing and then find a way to fix the damage and turn it into an advantage against a villain.
In a Tony Stark Avengers toy fanfiction, imagine the toys are actually miniaturized versions of the real heroes. Tony Stark's toy is the most advanced. It can repair the other toys when they get damaged. A villain tries to steal the Stark toy to reverse - engineer its technology for evil purposes. The other toys, with the leadership of the Stark toy, must fight to protect themselves and the world from this threat.
She could be kidnapped by a villain who wants to use her as leverage against Tony Stark and the Avengers. So the Avengers have to work together to rescue her. During the rescue mission, they discover some new abilities she has that she didn't even know about herself.
In a fanfiction scenario, Tony Stark could be hurt emotionally. For example, if there's a rift in the Avengers team and some of his closest friends turn against him. This could lead to him isolating himself and getting into a downward spiral of self - doubt and pain, which is really interesting to explore in fanfiction.
In a time travel fanfiction involving Morgan Stark, perhaps she travels back in time to a crucial moment in her father's life, like the battle of New York. She uses her knowledge from the future to help him, but also has to be careful not to disrupt the timeline too much. Morgan might end up forging a new bond with her father that was different from the one she had in her own time.
Tony Stark might hide his PTSD in fanfiction because he doesn't want to be a burden. He's always been the one to solve problems, so showing vulnerability is difficult for him.
Tony Stark's injuries in fanfiction can have a huge impact on the story. If he's physically injured, it might force him to rely on other Avengers more, which could change the team dynamics. For instance, he might have to trust Steve Rogers completely when it comes to leading the team in his absence.
