There are many possibilities. Maybe Paul has already told his family some things about Percabeth, so they are well - prepared and excited to meet them. Or perhaps they are completely in the dark and are shocked at first. But as they get to know Percabeth better, they see their kindness, loyalty, and courage, and start to accept them as part of their extended family in the fanfiction world.
Most likely, the baby would be received with a mix of excitement and caution. The campers would be excited because it's a new addition, but also cautious as they don't want any harm to come to it. Some might be a bit overprotective right away.
They might have an awkward start. For example, Percy could be nervous and say something silly at first. But then, Annabeth's intelligence would shine through as she tries to make good conversation with Paul's family.
She might be received very well. Derek's family could immediately like her because of her kind heart and the fact that she's a good friend to Derek.
In a pregnant fanfiction, their relationship would deepen. There would be a new level of intimacy. They would have to communicate more about their future and their hopes for the baby. Percy might become more domestic, like helping Annabeth with household tasks. And Annabeth would rely on Percy more for emotional support during the hormonal changes of pregnancy.
Some of the Avengers might be really curious. Thor, for example, might be interested in Percy's relation to the sea, as he has his own connection to water with his powers. Iron Man might be a bit skeptical at first, thinking they're just some kids with strange powers. But once he sees what they can do, he'd be impressed.
Well, it could be that Paul's co - workers are somehow magically transported into the world of Percabeth. Maybe they initially don't understand the whole demigod thing and there are a lot of comical misunderstandings. For example, they might mistake Percy's sword for a really strange looking kitchen knife. Then they gradually get to know Percy and Annabeth and start to admire their relationship and their heroic deeds.
Well, at first, Annabeth's dad might be quite hostile. He'd be worried about his daughter getting involved with someone like Percy who is constantly in danger. But if Percy shows his loyalty to Annabeth and his good nature, like by being polite and showing respect for Annabeth's family, her dad could gradually change his attitude. Maybe he'd start to see Percy as a brave young man who can protect Annabeth rather than a threat.
Obviously, Percy and Annabeth from Percabeth are main characters. As for Paul's co - workers, we could have a really chatty one named Mark who is always asking questions about the demigod world. And then there could be a more serious co - worker like Susan who is initially skeptical about the whole situation. These co - workers' different personalities will interact with Percabeth in different ways.
Percy could use his powers over water to his advantage. For example, he could create water barriers to protect them from attacks or use water to wash away any tracks they leave. Annabeth's intelligence would help them make smart decisions about where to go and when to move. They'd also likely rely on each other's strengths, like Percy's physical strength and Annabeth's strategic thinking.
His abilities would be seen as quite extraordinary. The Fairy Tail members would likely be amazed by Naruto's shadow clone jutsu as it allows for multiple tasks to be done simultaneously. His rasengan, being a powerful concentrated attack, would be respected. They might initially be a bit confused about how chakra works compared to their magic, but would soon realize its potential in battles.
