Well, initially the Avengers would be on high alert. They've dealt with Loki's mischief before and would assume his children are just as much trouble. But as they interact, they could start to see the differences. Maybe the children are more innocent or have been misled by Loki. This could lead to a change in the Avengers' attitude from hostility to something more like mentorship or protection, especially if the children show a willingness to be good and not follow in Loki's more devious footsteps.
Some of the Avengers, like Thor, might have a more complex reaction. Since he is Loki's brother, he may feel a sense of responsibility towards the children. Others like Captain America would be cautious but fair, trying to assess if they are a threat. Iron Man, on the other hand, would probably be sarcastic and make some snarky remarks while sizing them up.
The Avengers' reaction would depend on their past experiences with Loki. If they have had many bad encounters with Loki, they would be very suspicious of his children. They would likely approach them with weapons drawn. But if they have seen a more redeeming side of Loki, they might be more open - minded. For instance, Hulk might just be confused and growl a bit until he figures out if they are friend or foe. Black Widow would be quietly observing, ready to act at a moment's notice.
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.
When the Avengers meet Lady Loki in fanfiction, their reactions would vary. Iron Man would probably start analyzing her, trying to figure out her weaknesses. Captain America, being the moral compass, would try to give her a chance to prove herself, but also be ready to fight if she betrays them. And Thor, he would have a mix of emotions, part anger from past experiences with Loki and part curiosity about this new form of his 'brother'. The more impulsive members like Hulk might just see her as a threat and react accordingly.
Tony Stark would probably be very intrigued. He'd want to study Loki's Jotun form, maybe even make some snarky comments about his blue skin. Steve Rogers, on the other hand, would be more cautious. He'd be ready for any potential threat that Loki might pose.
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.
They might be cautious. After all, they don't know her and she's from Percy's world which could be full of unknowns for them.
If Loki impersonated Thor, the real Thor would be furious when he found out. The other Avengers, like Iron Man, might initially be confused but then quickly realize something is off. Iron Man would likely use his technology to detect the impostor. Hulk might just smash first and ask questions later when he senses something wrong with 'Thor'.
The Avengers might react in different ways. Steve Rogers would probably be polite but firm in getting to know Peter's boyfriend. He'd want to ensure that he was a good influence on Peter. Thor, on the other hand, might be a bit more boisterous. He could either be really friendly and enthusiastic, or his loud and powerful presence might accidentally scare the boyfriend a bit.
Well, if the Avengers meet Peter's girlfriend, it depends on their own personalities and what they've heard about her. If they've heard good things from Peter, some like Spider - Man himself would be very excited to introduce her. The Avengers might be a bit cautious too, because they don't want any harm to come to Peter or their team because of her. For example, if she has a past that's a bit murky, they'll be on high alert. But if she's just a normal, nice girl, most of them would eventually warm up to her, except maybe those who are more cynical like Loki (if he was somehow part of the Avengers in this fanfiction), who would always be suspicious.
Thor would likely be the most affected. He has a history with Fenrir as it is from Asgardian mythology. He might be cautious at first, but also feel a sense of kinship. Iron Man would probably be all about analyzing Fenrir, trying to figure out its weaknesses and strengths. Captain America would be on guard, ready to defend his team, but also open to the idea of Fenrir not being an enemy if proven so.
The OC might be terrified at first. After all, being kidnapped by Loki is no joke. But they could also quickly gather their courage. Maybe they would try to talk to Loki, to understand his motives. If the OC is smart, they would know that Loki has his own reasons for doing things and might be able to find a way to reason with him.
