Well, perhaps the Avengers initially suspect Loki's daughter of some mischief like her father. But as they get to know her, they find out she's actually trying to make amends for Loki's wrongdoings. She could have some unique powers that both intrigue and worry the Avengers.
Thor might be conflicted. He'd see his nephew/niece but also remember Loki's treachery. Iron Man would probably be sarcastic at first, making remarks about the family genes. Captain America would be more cautious and diplomatic, wanting to give her a chance but also being on guard. Black Widow would try to read her body language and motives right away.
The idea of the Avengers meeting Loki's wife in fanfiction is exciting. It could start with a tense encounter. The Avengers, being suspicious of Loki's motives, would be on guard around his wife as well. But if she is an intelligent and diplomatic character, she could break the ice. She might share stories about Loki's past that the Avengers didn't know, like how he was once a hero in his own realm before being corrupted. This could humanize Loki in the eyes of the Avengers and lead to a new alliance or at least a truce between them.
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.
Well, in such a fanfiction, there could be a lot of conflict. Maybe Loki's son has some sort of hidden power that the Avengers initially fear. But then they might realize he's not as bad as they thought and try to help him control his powers. Or perhaps Loki's son is on a mission to prove himself and the Avengers see him as a threat at first.
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.
She could fit in as a strategist. Since Loki was known for his cunning, she might inherit that trait and be able to come up with clever battle plans for the Avengers.
Loki's daughter in Avengers fanfiction could bring a whole new dynamic. She could befriend some of the younger Avengers like Spider - Man or Shuri. Together, they could form an unexpected team within the larger Avengers group. Her powers might be a combination of Loki's magic and something new. She could use her abilities to infiltrate enemy strongholds and gather intelligence for the Avengers. Also, she might have a moral conflict, being part Loki and part someone who wants to do good, which would add depth to the story.
Well, in a fanfiction scenario, Loki might initially try to deceive the Avengers again. But Sylvie could be the wild card.

And Iron Man would surely come up with some sarcastic remarks about this new duo.
Well, if the Avengers meet Lady Loki in fanfiction, it could lead to some really interesting character dynamics. Lady Loki, being the mischievous character she is, would likely stir things up. She could play mind games with the Avengers, especially with those who are more trusting like Captain America. On the other hand, characters like Iron Man might be more suspicious of her from the start. And Thor, having a connection to Loki, would have a very complex reaction to Lady Loki's presence.
