Another plotline could involve Percy getting caught in the middle of a power struggle between different factions of the Olympian gods. He would have to choose sides carefully, not just based on loyalty but also on what he believes is right for the future of the Olympian world and the mortals who are affected by their actions.
Maybe there's a plotline where Percy discovers a long - lost relative who has some crucial information about his past or his powers. This could lead to a whole new adventure as he tries to piece together the mystery. For example, this relative could be from a forgotten branch of his family tree that has a special connection to an ancient power source in the Olympian world.
Well, Percy is surely one of the main characters. He is likely to be the central figure around which the story revolves. He has his unique powers and personality that drive the plot forward.
One idea could be Percy having to deal with a new, powerful enemy that even the Olympians are afraid of. He has to use his unique skills and form new alliances.
One possible plotline could be Percy being betrayed by the gods and thus deciding to take on Olympus. Maybe he discovers some dark secrets about the gods' rule that make him believe destruction is the only way to bring true justice.
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.
In this fanfic, it could be that the power of Olympus has become corrupt. Percy, being a hero with a strong sense of justice, decides that the only way to set things right is to destroy it and start anew. He could first target the symbols of the gods' power, like Zeus' lightning bolt. With the help of his friends from Camp Half - Blood, he might stage a full - scale assault on Olympus, using their combined skills and powers to take on the gods and their defenses.
One common plotline is Percy finding out that the Olympians have been using him all along. For example, they might have sent him on dangerous quests not just to save the world but also to gain more power for themselves. Another could be Percy being betrayed by a close friend or ally who is working for the Olympians' self - serving plans. Maybe they set him up to take the fall for something he didn't do.
A young demi - god who looks up to Percy and wants to be his apprentice. This character could bring some new energy and naivete to the story, and Percy would have to take on a mentoring role.
A really cool plot twist could be Percy finding out he has a long - lost sibling who is on the side of the Titans. This would create a huge internal conflict for Percy as he has to decide between his loyalty to his new - found family and his duty to the Olympians. It would also add a lot of drama and tension to the story as he tries to sway his sibling to the right side.
Perhaps a plot twist where Percy discovers that his own powers are somehow linked to the Bane in a way he never expected. Like his ability to control water is actually being manipulated by the Bane to cause chaos in the ocean realm, which would put him in a really difficult position of having to figure out how to break that connection while still using his powers.
One idea could be Percy going on a quest to find a lost artifact that has the power to restore a dying part of the godly realm. This would involve him facing new monsters and making unexpected alliances.
