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.
One great Thor Loki Tony fanfiction is 'The Triumvirate'. It weaves an interesting story where their different powers and personalities collide and cooperate in a unique way. The author does an excellent job of capturing the essence of each character.
Natasha Romanoff would be an interesting character to include. She's very perceptive and could be the one to first notice the change in Loki's behavior towards Tony. And then there's Bruce Banner. His scientific mind could interact with both Loki's magic and Tony's technology, and he could also offer some unique perspectives on their relationship, perhaps warning Tony about the risks of getting involved with Loki.
There are several great authors. One author that stands out is [Author Name 3]. Their writing style is very descriptive, which really brings the story to life. They do an excellent job of portraying Loki and Tony's relationship during the pregnancy. Also, [Author Name 4] is quite popular. Their stories often have unique twists and turns that keep readers hooked, especially when it comes to the Mpreg aspect and how it affects the two characters.
Fanfiction.net also has some good Loki Tony fanfictions. You might need to do a bit more digging compared to AO3, but there are some hidden gems there. Look for stories with a lot of reviews, as those are usually quite good.
There is also 'A Meeting of Minds: Loki and Tony'. This story delves deep into the minds of both characters. It starts with a rather hostile encounter between them but gradually, as they understand each other's motives and capabilities, they form a unique bond. It's a great exploration of their personalities.
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.
