One plot idea could be that they discover their 'brotherhood' through some magical or scientific accident. Maybe they have to team up to stop a common enemy, like an ancient, powerful being. They could start off hating each other because of their different personalities (Tony's brashness vs Loki's slyness), but as they face challenges together, they learn to respect and care for each other.
A plot could involve Loki using his magic to get into Tony's head. Tony, in turn, uses his technology to try and understand Loki better. This creates a strange dynamic where they are both trying to outwit each other at first, but then realize they are more alike than they thought. They might then combine their powers, Loki's magic and Tony's tech, to save the world from a threat that neither could face alone.
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.
In fanfiction, Tony Stark and Loki often make for an interesting pairing. Their personalities are quite different. Tony is a genius inventor, a bit of a playboy, and very human in his flaws. Loki, on the other hand, is a complex Asgardian with his own motives and a penchant for mischief. Fanfiction writers might explore how their different worlds collide. Maybe Loki's magic and Tony's technology could either clash or combine in unique ways. For example, they could be forced to work together against a common enemy, leading to a begrudging respect for each other.
Maybe Loki gets stranded on Earth and Tony offers him shelter in Stark Tower. They start to have long conversations about power, responsibility, and their respective places in the universe. Eventually, they team up to fight a common enemy, like a new powerful alien threat that neither of them could face alone.
Maybe in a fanfiction, there is a cursed ballet. Tony Stark and Loki are both drawn to it for different reasons. Tony because of his love for all things unique and Loki because he senses dark magic. They have to team up to break the curse. During this process, Loki has to use his ballet skills (which he has been hiding) and Tony uses his tech to figure out the source of the magic. As they work together, they form an unlikely bond.
Well, one possible plot could be that Loki, being his mischievous self, initially tries to trick Tony Stark. But Tony, with his intelligence, sees through some of Loki's tricks. They might end up in a battle of wits, with Loki trying to outwit Stark's high - tech gadgets and Stark trying to outsmart Loki's magic. Eventually, they could find common ground in their mutual love for power and knowledge and form an unlikely alliance to face a greater threat in the Marvel universe.
One interesting story could be where Loki and Tony Stark are forced to team up against a common enemy from another dimension. They start off hating each other but gradually learn to respect one another's skills as they fight side by side.
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.
