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 the fanfiction, future Loki's interaction with the Avengers can be really complex. At first, they might see him as a threat, especially those like Captain America who are very cautious about trust. But as time goes on, Loki could show his value. He might use his mischievous nature in a positive way, like tricking the enemy into revealing their plans. And with Thor in the group, there would be a whole family - dynamic thing going on. Loki would have to navigate his relationship with his brother while also trying to earn the trust of the other Avengers.
One possible plotline could be that future Loki comes with a warning about a new threat that the Avengers initially don't believe. For example, he might tell them about a powerful being from another dimension that is slowly making its way to Earth. Another plotline could involve future Loki trying to redeem himself in the eyes of the Avengers by helping them prevent a disaster that he was partly responsible for in his own timeline. He could use his knowledge of magic and trickery to outwit the new enemy.
Loki's character development can also involve him learning about the value of teamwork and friendship. As he interacts with the Avengers more, he starts to see the benefits of working together rather than against them. He might share his knowledge of magic and Asgardian lore with the team, which in turn helps them in their battles. This exchange also helps him grow as a character and become more integrated into the group.
In many Thor Loki Avengers fanfictions, Loki's character development often starts from a place of being the villain. He then gradually realizes the value of his relationships, especially with Thor. For example, in some stories, after seeing the loyalty of the Avengers to each other, he begins to question his own actions. He might start to show remorse for his past deeds like the attack on New York.
In fanfiction, Loki's interaction with the Avengers would be complex. He has a history of being an enemy, but also has moments of reluctant alliance. Sylvie, being a variant of Loki, would bring her own perspective. She might view the Avengers as symbols of the power structures she wants to undermine. Loki could be caught in between, trying to balance his new relationship with Sylvie and his past with the Avengers. The Avengers would be on guard, not fully trusting either of them.
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.
In some fanfictions, Loki might use his magic to outwit the enemies that the Avengers are facing. For example, he could create illusions to deceive the villains and lead them into a trap.
In many such fanfics, the Avengers might find Loki through various means. Sometimes it could be intelligence they gather about the location where he is being tortured. For example, they might intercept a message from Loki's captors or notice some strange energy signatures that lead them to the place.
The Avengers' interaction with Loki's kids in fanfiction would be complex. Thor, being Loki's brother, might have a more nuanced view. He could try to guide the kids towards the right path. Iron Man, on the other hand, would likely use his technology to keep an eye on them. And the female Avengers like Scarlet Witch might try to empathize with the kids if they seem lost or confused. There would be a mix of suspicion, hope, and attempts at understanding in these interactions.
Loki would likely use his vampire - enhanced abilities to his advantage when interacting with the Avengers. He could be more stealthy and use his hypnotic powers on some of the members. For example, he might try to turn them against each other.
