Maybe in the fanfiction, there's a villain who can manipulate technology and is targeting Stark Industries. Deadpool, being his wild self, decides to team up with Tony Stark to take on this villain. Along the way, they have many comical exchanges as Deadpool constantly breaks the fourth wall and Stark tries to keep him in line with his high - tech gadgets.
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.
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 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.
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.
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.
One idea is that the Tony Stark Avengers toy is a prototype for a new type of weapon in the Avengers universe. The bad guys get wind of it and try to steal it. The other Avengers toys, with Tony Stark at the helm, have to protect the prototype. They use their unique toy - like abilities, like the Hulk toy's super strength and Captain America's shield - throwing ability of the toy version, to fend off the attackers.
Another plot could involve Wanda accidentally getting trapped in one of Tony's experimental virtual realities. Tony has to enter the VR world himself to rescue her. Along the way, they learn more about each other's past traumas and form a deeper bond as they fight their way out.
Maybe the twin sister has a different approach to superheroing. While Tony is all about the high - tech gadgets and flashy suits, she focuses on using her intelligence to create solutions for the world's problems on a more grassroots level. She could be involved in projects like improving education in underprivileged areas or finding sustainable ways to provide clean water.
One idea could be that in this other world, Tony Stark is a medieval blacksmith who uses his brilliant mind to create advanced weapons within the limitations of that era. He might discover a new metal ore with properties similar to vibranium and use it to make armor for the local knights.
One plot idea could be that Tony Stark creates a new high - tech suit for Spider - Man. This suit has unique features like enhanced web - shooters and advanced sensors. Another idea is that Spider - Man has to save Tony Stark from a new villain who has a vendetta against Stark Industries. Maybe the villain has some tech that can neutralize Iron Man's suits, and Spider - Man has to use his agility and quick thinking to outwit the foe and rescue Stark.
