Natasha Romanoff could also be one of the first. She is good at understanding people's motives and getting into their heads. She might see the potential in Loki and decide to approach him, using her charm and intelligence to start a friendship.
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.
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.
One plotline could be Loki initially resisting the Avengers' attempts to adopt him. He might be suspicious of their motives, thinking it's a trick. But over time, as they show genuine care, he starts to open up. For example, Thor could be a key factor in getting Loki to trust the Avengers, as he vouches for their good intentions.
Well, Hulk could be involved in a more physical sense of bullying. His uncontrollable rage might be directed at Loki in the fanfictions. Black Widow, with her skills in manipulation, could also play a part in making Loki's life difficult. Hawkeye, being a loyal member of the Avengers, might follow the group's lead and be part of the bullying, perhaps using his archery skills to intimidate Loki.
Obviously, Loki is one of the most popular. His complex personality, with his mischievous and often ambiguous moral compass, makes him a very interesting character to write about. Writers can explore his motives, his past traumas, and his relationships with other characters in many different ways.
Thor is also very popular. His relationship with Loki is a key aspect in many fanfictions. His strong - willed and noble nature contrasts with Loki's more devious ways. Also, his power as the God of Thunder adds an exciting element to the stories. He can be shown as the one trying to bring Loki back to the right path or as a powerful ally in battles against common enemies.
I think it would be Spider - Man. Since he's also relatively young and has a sense of humor. He would be able to relate to Robin on a more personal level compared to the other Avengers. They could start chatting about their cool gadgets and how to use them in different situations.
Some Avengers might find it entertaining. For example, Thor could chuckle at the creative ideas about his brother. Others like Captain America might be a bit bewildered. He comes from a more straightforward world of stories, and fanfiction can be really out - of - the - box.
Obviously, the Avengers like Iron Man, Captain America, Thor etc. would be main characters. And Loki's children, whoever they are in the fanfiction's interpretation. Maybe there would be a new character created specifically for this story as well who becomes important in the interactions between the two groups.
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.
