One idea could be that Tony Stark goes undercover in a small, struggling tech startup within his own company. He discovers a brilliant but overlooked engineer who has an idea that could revolutionize the whole industry. He then has to decide how to promote this person without revealing his true identity right away.
Pepper Potts could be an interesting addition. She could be in on Tony's undercover plan and be his contact on the outside. She could also provide some comical moments when she has to cover for Tony or when she tries to communicate with him secretly while he's undercover.
One idea could be a story where Tony discovers a hidden diary of Howard's that reveals secrets about his early inventions and the true motives behind some of his actions. This could lead to Tony having a new perspective on his father and his own work.
One plot idea could be that Ziva and Tony are undercover as a married couple at a high - society event. They have to blend in and gather intel on a criminal who is using the event to launder money. Another could be that they are undercover in a dangerous cult to rescue a kidnapped agent, and during their time there, they start to realize new things about each other. A third idea is that they go undercover as rival spies in an international arms deal, but their fake rivalry starts to turn into something more real and they have to deal with their feelings while still completing the mission.
One idea could be that Deadpool gets accidentally teleported into Stark Tower. He then proceeds to annoy Tony Stark with his non - stop chatter and crazy antics. Stark, at first, is irritated but then realizes Deadpool's skills could be useful in a new project he's working on.
A great plot could involve deaged Tony getting involved in the early days of Stark Industries. He might see things from a new perspective and try to change the company's direction towards more ethical practices right from the start. This could lead to all kinds of adventures as he tries to convince the adults around him to listen to him. He could also form unexpected friendships with employees who later become important in the 'grown - up' Tony's life.
Maybe the fanfiction could be about Tony adopting a child with special powers. He has to protect the child from those who would misuse the powers while also helping the child understand and control them. This could involve lots of action scenes and emotional bonding between Tony and the adopted child.
One idea could be that Tony Stark is brainwashed by a powerful enemy. This enemy uses some advanced technology to manipulate his mind, turning him into a villain who starts attacking his former allies. He might use his Iron Man suits in new and devious ways against the Avengers.
A plot idea could be that a deaf hacker tries to break into Stark Industries' systems to prove a point about security flaws. Tony catches them but is intrigued by their skills. They start working together to improve security, with the deaf hacker using their unique observational skills. Another idea is that a deaf artist creates a piece inspired by Tony Stark, and he is so moved that he invites the artist to his tower. There, they face a threat together, and the artist's deafness becomes an unexpected advantage in outwitting the enemy.
Well, perhaps they are undercover in a foreign country. They have to blend in with the local culture, which leads to some humorous situations like Tony trying to learn the local dance or Ziva struggling with the language but still managing to intimidate people. And then there's the danger aspect, where they discover a terrorist cell operating within the city they are in and have to stop them without blowing their cover.
Another plot could involve the reaction of the other Avengers. They might be initially confused or even a bit worried about Tony's new look and abilities. But as he starts using them to their advantage, they come to accept and even rely on this new version of Tony Stark.
