A powerful new demigod who is jealous of Percy's secret power could be the main antagonist. This demigod might think that Percy doesn't deserve such a power and tries to steal it for himself. He could be a son or daughter of a minor god who feels overlooked and wants to use Percy's power to gain recognition.
A possible plot for a 'Percy Jackson Secret Power' fanfiction could involve Percy having a secret power of teleportation. But this power is not fully under his control at first. He might accidentally teleport to strange and dangerous places. One time he could end up in the middle of a Titan's lair. As he tries to master this power, he discovers that it has a connection to an ancient prophecy. His friends, like Annabeth, help him figure out how to control it and use it for the greater good.
Well, in many fanfictions, if Percy Jackson is made into the God of Power, it often gives the author a chance to explore different power dynamics. He could potentially have the power to influence the fates of other demigods. This would add a whole new layer of complexity to the existing Percy Jackson universe. He may also have new responsibilities that come with this godly status, which could lead to internal conflicts as he tries to balance his old self with this new, all - powerful identity.
In Percy Jackson fanfiction, possession power can be a really cool concept. It could be a power that a character gains or something an enemy uses against the demigods. For example, a new villain might have the ability to possess the minds of the half - bloods at Camp Half - Blood, causing chaos among them. This would add a new level of danger and intrigue to the story.
Another way could be via some sort of magical artifact. For example, he discovers an ancient amulet that has the power to enhance his natural abilities. When he touches it, it starts to merge with his essence, gradually making him stronger and endowing him with new powers like the ability to control different elements related to water, not just manipulate it.
Another possibility is that Percy is recruited by a secret organization that has discovered his demigod powers. They see his potential as a secret agent because of his combat skills, quick thinking, and ability to adapt in dangerous situations. In this fanfiction, he might have to work with other agents who are initially skeptical of his 'weird' powers but soon come to respect and rely on him.
One significance is that it expands the possibilities of his character arc. He goes from a hero to a god - like figure, which is a huge transformation. It allows for different types of challenges and growth. For example, he may face moral dilemmas about how to use his new - found power.
Often, possession power in Percy Jackson fanfiction is shown as a very dark and insidious ability. It can be used to make characters act against their will. For instance, a possessed character might turn on their friends, like if a demigod is possessed and then tries to harm others at Camp Half - Blood.
On the positive side, the power he absorbs might help him save the world more effectively. He could be able to defeat stronger enemies and protect his loved ones better. However, he would also have to learn to control this power, which could be a long and difficult process. If he fails to do so, he might accidentally cause harm to those around him.
He could also face challenges related to the knowledge required to use his power effectively. In fanfiction, there might be ancient texts or prophecies that he needs to decipher in order to fully understand and utilize his new powers. But these texts could be written in a long - lost language or be guarded by powerful entities, making it difficult for him to access the necessary information.
