One common theme is the shock and adjustment of the Avengers. They have to get used to the idea of Loki, who was once an enemy in some cases, being pregnant. Another theme is the protection of Loki and his unborn child. The Avengers often come together to safeguard them from potential threats. And there's also the theme of Loki's internal struggle, dealing with his new condition while also having to interact with the Avengers who have a complex history with him.
One great Loki pregnant Avengers fanfiction is 'Loki's Unexpected Miracle'. It delves into how the Avengers react to Loki being pregnant. Another is 'Pregnant Loki and the Avengers' Bond' which focuses on the unique relationships Loki forms with the Avengers during this time. And 'Loki's Pregnant Journey with the Avengers' shows how Loki's pregnancy changes the dynamics within the Avengers group.
Thor would be a likely candidate. Since he is Loki's brother, he already has a connection with him. Thor might be the one to convince the other Avengers to give Loki a chance and be the first to reach out and try to befriend him in this new situation.
Future Loki might interact with the Avengers in a cautious way. He knows their past opinions of him and tries to prove himself. He could start by sharing small bits of useful information. For example, he might tell Iron Man about a weakness in a new enemy's technology.
In this fanfiction, Loki might interact most with Hulk. It would be an interesting dynamic as Loki is a master of manipulation and Hulk is, well, the Hulk. Loki could either try to use Hulk for his own purposes, which would be very dangerous, or he could end up on the wrong side of Hulk's anger. But at the same time, it could also lead to some unexpected moments of understanding or at least a begrudging respect between them.
He would probably interact a lot with Thor. Since they are brothers, there is a pre - existing relationship full of complexity. Also, he might interact with Iron Man quite often. Tony Stark's sarcastic nature and Loki's trickery could lead to some really interesting exchanges, either in the form of verbal sparring or working together on some high - tech and magic - combined projects.
Well, Thor might be a bit shocked at first. He'd probably be amused by some of the wilder interpretations of his brother in the fanfiction. Captain America, on the other hand, would likely be confused by the whole concept as it's so different from the traditional stories he's used to. Iron Man would probably make sarcastic comments about how creative the fans are in coming up with these stories.
In these fanfictions, one characteristic is the use of Loki's shape - shifting abilities for comical purposes. He could transform into different Avengers and act in a way that is completely out of character for that person, causing confusion and laughter. Also, the stories often play with the power dynamics among the Avengers and Loki. Loki might try to outwit them in a humorous way, like in a game or a competition. The humor also comes from how the Avengers, who are used to serious threats, deal with Loki's more light - hearted and silly challenges.
There's a fanfic called 'Loki's Redemption in Thor's World'. This one focuses on Loki trying to find his place in Thor's world after all the chaos he has caused. It shows his struggle to be accepted and how Thor is gradually coming to terms with having Loki back in his life. The writing style is engaging and really makes you feel for both characters.
