It could be a jealous rival. This rival might have always been envious of Percy's popularity and skills. So, they manipulate Percy's friends into betraying him to get Percy out of the way and take over his position.
One possible plotline could be that Percy discovers his so - called friends have been secretly working against him all along. Maybe they spread false rumors about him, which makes everyone in his world turn against him. He then has to go on a journey alone to clear his name.
One possible reason for Ash getting betrayed in the fanfiction could be misinformation. A villain might spread false rumors about Ash, making his friends believe he has done something wrong. His friends, without verifying the truth, turn against him. It's a sad situation where lack of communication and trust plays a big role.
Most likely not. The concept of 'getting everyone pregnant' is a very adult - like and inappropriate theme in general. Fanfictions should usually adhere to certain moral and ethical standards, and this title gives the impression of something that goes against those norms.
Isolation is a common theme. Percy, being betrayed by everyone, is left all alone. He has to fend for himself and figure out how to deal with the situation without any support. Another theme could be self - discovery. Through this difficult time, Percy may start to learn more about his true self, his strengths, and his limits.
One common theme is the shattering of trust. When Percy gets betrayed, it's all about how that trust he had in someone is completely broken. This often leads to him feeling isolated and alone.
Percy would likely feel a great sense of hurt and confusion. He might question his own judgment in trusting Annabeth. He could become more withdrawn and less trusting of others in general.
Percy might initially feel a great deal of anger. He's been wronged by those he thought were his friends. But then, with Annabeth by his side, he could start to focus on finding out the truth. He might use his skills, like his combat abilities and strategic thinking, to figure out who or what is behind the betrayal.
In a fanfiction like this, it could be that Percy's powers or abilities were starting to make others jealous. His friends might have felt overshadowed and, in a moment of weakness, turned on him. Also, there could be an outside influence, like a dark force that was manipulating people's minds to make them betray Percy.
I'm not sure specifically as I haven't read that particular fanfiction. But it might be a very strange and inappropriate concept if taken literally. It could potentially be a satirical or very out - there take on a story involving a character named Percy, perhaps in a fictional universe where some sort of crazy magic or situation causes unexpected pregnancies. However, this is just speculation.
