There are fanfictions where Loki uses his magic to help Tony with some of his tech experiments. In these stories, Loki is intrigued by Tony's intelligence and the advanced technology that he has created. Tony, on the other hand, is fascinated by Loki's magic and they exchange knowledge, leading to some amazing inventions and magical - tech hybrids.
Some Tony and Loki fanfictions explore the idea of Loki being stranded on Earth and Tony taking him in, not really believing who he is at first. As time passes, Loki starts to adapt to the human world with Tony's help and guidance. They get into all sorts of comical and also rather deep situations together, like when Loki tries to understand the concept of modern-day friendships through Tony's friends.
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 possible plot could be that Loki, with his mischievous nature, initially tries to deceive Tony for some personal gain. But as they interact more, they discover they have common interests in advanced technology and magic. They start to work together on a project to protect the Earth from a new threat that neither of their individual powers could handle alone. Their relationship evolves from mistrust to a deep friendship and they become mates in the sense of being reliable partners.
In the fanfiction, Loki may have developed a sense of respect or even friendship for Tony. They are both very intelligent characters. Loki might admire Tony's ingenuity and courage. So when he realizes that Tony is in danger in Siberia, his new - found feelings for Tony drive him to save his life. Also, Loki might be bored with his usual villainous ways and wants to do something good for a change, and saving Tony seems like a good start.
At first, it would be rocky. Loki is used to being a trickster and Tony is a bit of a control freak. But over time, they'd start to respect each other. Loki would see Tony's intelligence and resourcefulness, and Tony would see Loki's power and potential for good. Eventually, they'd become like family, looking out for each other.
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.
In fanfiction, Loki and Tony's friendship can be really interesting. They are both complex characters. Loki, with his mischievous nature, and Tony, the brilliant inventor. Their friendship might start from a mutual understanding of being different from the norm. Maybe Loki sees Tony's genius as something worthy of his respect, and Tony might be intrigued by Loki's otherworldly powers.
I really like 'A Meeting of Minds'. In this fanfiction, Loki and Tony start off as adversaries but as the story progresses, they find common ground and a unique bond forms. The author does an excellent job of writing their dialogues, making it feel very real.
Another plot might involve the Avengers trying to figure out how to deal with de - aged Tony and Loki. They could be worried about Loki's intentions since he's usually a villain, but at the same time, they have to take care of a child - like Tony. This creates a lot of comical and tense situations.
One possible plot could be Loki initially trying to use Tony for his own gain but then truly falling for him. Maybe Loki, in his usual sly way, gets close to Tony to access some of Stark's technology, but as time passes, he discovers Tony's charm, intelligence and vulnerability, and his feelings turn sincere.
One great Loki and Tony slash fanfiction is 'The Unlikely Bond'. It delves into how their different personalities, Loki's mischievousness and Tony's cocky charm, create an interesting dynamic. They start off as adversaries but gradually find themselves drawn to each other in ways they didn't expect.
