A third plotline could be Percy being raised by the gods in a different era. He might be sent back in time to the age of the Titans and have to grow up among them while still retaining his loyalty to the Olympians. This would create a lot of internal conflict for Percy as he tries to figure out how to survive and still uphold his values.
In some 'Percy Jackson Raised on Olympus' fanfictions, there could be a plotline about Percy uncovering long - hidden secrets of Olympus. For example, he might discover a forgotten prophecy that has implications for the entire pantheon. Also, his interactions with the nymphs and other mythical creatures in the Olympian realm can make for an exciting story. Maybe he has to protect them from a new threat that is emerging within the boundaries of Olympus itself.
Well, it could start with Percy being framed for a crime he didn't commit by the gods. This false accusation makes him feel extremely betrayed. He then has to go on the run while trying to prove his innocence. Along the way, he meets other outcasts and together they form a resistance against the gods. They might try to find a way to hold the gods accountable for their actions and create a new order where demigods are treated more fairly.
A third plotline might be Percy's newfound powers or abilities due to being raised by the Hunt. He could develop enhanced senses, like better vision at night or a keener sense of smell. This would not only help him in hunting but also in facing off against enemies. He could use these powers to protect the Hunt from threats that they haven't encountered before.
One possible plotline could be Percy challenging the gods' unfair rules. For example, he might snap at them for always using demigods as pawns in their games. Another could be Percy standing up for the rights of other minor demigods who are often overlooked by the gods. Maybe he decides to form a sort of demigod union to negotiate with the gods for better treatment.
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.
One interesting plotline could be Aphrodite taking a special interest in Percy for a quest related to love and beauty. Maybe she tasks him with finding a lost artifact that has the power to enhance or destroy love. Another could be Percy falling under a love spell cast by Aphrodite, which causes chaos among his friends as he starts acting out of character. And a third one might be Aphrodite using Percy as a pawn in a love - related game among the gods, where his actions and decisions have far - reaching consequences for the relationships between the deities.
One interesting plotline could be the siblings going on a secret quest together without the knowledge of Chiron or the other campers. They might face a new and unknown monster that tests their combined skills.
In some fanfictions, a centurion discovers a long - lost prophecy that involves Percy. This could lead to a race against time as they try to figure out the meaning of the prophecy and prevent a great disaster. Maybe it involves a new Titan rising and they need Percy's unique connection to the sea gods to stop it.
Maybe in the fanfiction, Percy's player side shows up when he has to navigate the complex social hierarchies of the demigod world. He could be seen charming different groups of demigods, from the children of Athena with his quick - witted remarks to the children of Aphrodite with his newfound 'player' charisma. This could lead to all sorts of adventures and conflicts as he tries to maintain his relationships while also keeping up his player image.
Another plotline could be Percy trying to find a way to clear his name and escape the prison. Along the way, he might make some unexpected allies among the inmates or even some prison staff who are sympathetic to his cause. This could lead to an epic adventure within the prison walls as he tries to gather evidence and outwit his captors.
