In some fanfictions, their relationship could be a bit rocky at first. Maybe the adopted daughter has a different view on how to use technology for good. But through various events and heart - to - heart conversations, they grow closer and learn from each other, with Tony learning to be more open - minded and the daughter learning the value of his experience.
Loki might interact with her in a rather mischievous way at first. He could play little tricks on her just to see her reaction, but also be secretly impressed by her intelligence, which she got from her father. For example, he might magically move her tools while she's working on a project, and then be amused when she quickly figures out how to get them back using her own smarts.
He would be extremely worried. Tony Stark, despite his tough exterior, loves his daughter deeply. He'd probably start by using all his resources to find her. He has access to advanced technology, so he'd likely use his Stark Industries gadgets to track her down.
Well, it could make her overly independent. Since she's being neglected by Tony Stark, she might learn to rely only on herself. She'll grow up faster, taking care of her own needs and making her own decisions without much guidance from her father.
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.
In fanfiction, their interactions can also be very tense. Tony might try to use his sarcasm and intelligence to taunt Thanos, while Thanos, with his calm and collected demeanor, would simply brush it off. Sometimes, Thanos might even admire Tony's tenacity in the face of such overwhelming power, which could lead to some interesting exchanges between them.
Naruto would probably be very excited to meet Tony Stark. He'd be asking a million questions about all the cool gadgets. Stark, on the other hand, might be a bit put off at first by Naruto's exuberance but would soon warm up to him when he realizes Naruto's skills. They'd likely end up sharing stories about their respective worlds.
Tony might interact with the inmates in a rather cocky way at first. He's used to being in control and having the upper hand. But as he gets to know them, he could start to see them as more than just criminals.
Tony would also likely expose her to the world of science and engineering from a young age. He might take her to his lab and let her play with non - dangerous parts while he works. This would help her develop an interest in those fields.
She might interact with Thor in a humorous way. For example, she could be constantly amazed by his godly powers and ask him all sorts of questions about Asgard. Thor, in turn, would be amused by her inquisitiveness. With Black Widow, she could learn self - defense and spy techniques. They would have a sister - like bond, with the Black Widow protecting her when things get tough. And with Hulk, she might be a bit scared at first, but then learn to calm him down using her gentle nature.
One interesting plotline could be the adopted daughter developing her own unique suit under Tony Stark's guidance. It shows her growth and the bond between them as she learns from the genius.
