How would the Avengers react when they meet Percy's girlfriend in fanfiction?

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.

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.

Well, in some fanfictions, there could be a lot of confusion at first. The Avengers might be really protective and question who Percy's girlfriend is and if she can be trusted. Maybe they'll test her abilities if she has any, thinking she could be a threat. It could also lead to some really interesting team - up scenarios where Percy's girlfriend helps the Avengers with a mission using her unique knowledge or skills.

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 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.

They would probably be shocked. Demigods have extraordinary abilities, like being able to control water or run super fast. Percy's mortal friends, who are used to a normal world, would be taken aback by such powers.

Iron Man would be angry. He'd probably use his technology to try and track Percy down. He might also start to review all the security protocols to make sure no other traitors could do the same. Thor would be more of the 'let's fight him head - on' type, but the other Avengers would have to hold him back until they have a proper strategy.

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.

In a fanfiction, the Avengers' reactions to Percy Jackson's powers would be complex. Natasha Romanoff would immediately start thinking about how to use Percy's powers to their advantage in a mission. Bruce Banner, as the Hulk, might be a bit envious that Percy has such a natural and controlled power, while his own transformation is more of a chaotic force. Steve Rogers would be in awe of Percy's connection to an ancient power source, the Greek gods. And Clint Barton would probably make some jokes about Percy being like a human water hose, but deep down he'd be impressed. Tony Stark would want to incorporate Percy's power - controlling abilities into some new technology, or at least try to understand the science behind it.

Percy would probably be very confused at first. He's used to dealing with threats from the world of Greek mythology, not superheroes like the Avengers. But once he realizes he's been kidnapped, he'd likely be angry. He'd try to find a way to escape using his powers, like controlling water to create distractions or even using it to overpower his captors.
