What are some interesting plotlines in 'Percy Jackson God of the Unseen' fanfiction?

Grover could be a strong ally. He's always been Percy's friend and would likely stand by him even with this new role. Grover's ability to sense things could be helpful in complementing Percy's unseen powers. Another potential ally could be Chiron. Chiron has a wealth of knowledge and would probably guide Percy in understanding and using his new powers.

In some fanfictions, Percy might be sent back in time to a period when the gods were more actively involved in battles. He then has to navigate the complex politics of the time, deal with the more primitive and violent versions of the gods, and use his modern - day knowledge and skills to change the outcome of some crucial battles. This could also lead to him changing the future in unexpected ways, creating a whole new set of challenges for him.

Another plotline could involve the eldest god having a prophecy related to Percy. This prophecy could force Percy to make difficult choices between his loyalty to his friends and his newfound role in the eldest god's plans. For instance, he might have to sacrifice a chance to save a friend in order to fulfill a greater purpose for the world as dictated by the eldest god.

In many fanfictions, a common plotline involves Percy being framed for a crime he didn't commit. He then has to clear his name while also fighting off the real culprits, which are often powerful monsters or devious demigods. Another plotline could be that a new prophecy emerges that only Percy can fulfill, but it puts him in direct conflict with some of his closest friends. Also, there might be a plot where a group of demigods decide to break away from the traditional Camp Half - Blood and form their own community, and Percy has to decide whether to join them or not.

Another plotline could involve Percy making a deal with the God of Death. In this scenario, he has to fulfill certain tasks in exchange for something he desperately needs, like saving a friend's life. This would put him in a series of dangerous and morally challenging situations as he tries to complete the tasks without sacrificing his own values.

One common plotline is Percy struggling to control his new powers as the God of Chaos. He might accidentally cause chaos in places he doesn't mean to.

Many fanfictions also have a plotline where Percy as the God of Tides has to deal with the consequences of his new power. He might accidentally cause a natural disaster due to his inexperience with his godly abilities. Then, he has to find a way to fix it while also facing the wrath of the other gods who are angry about the disruption he has caused.

Some fanfictions might explore what would happen if Percy had a different parentage. Maybe he was the son of a different god or goddess, like Hecate. This would completely change his powers and the way he interacts with the magical world around him. He could learn new types of magic and have a whole new set of challenges and adventures.

A possible plotline could be that the hermit is actually a forgotten hero from the past. He has been in hiding all this time but now his past is catching up with him. As he tries to keep his identity a secret, events unfold that force him to face his former life and the consequences of his actions long ago.

One interesting plotline could be the Seven facing a new, more powerful enemy that is a combination of different mythological creatures. This would test their teamwork and individual powers in new ways.
