Well, it could mean a huge power boost for Percy. Hyperion is a powerful Titan, so Percy might gain abilities like enhanced strength, maybe some new control over light or the sun. It could also change his status among the demigods, making him even more of a force to be reckoned with.
When Percy absorbs Hyperion, it might have some psychological implications too. He has to deal with the essence of a Titan, which could be a struggle. Maybe he starts to see things from a more 'Titan - like' perspective in terms of power and control. Also, in terms of his relationships, other demigods might be wary of him now that he has this new Titan - infused power.
He becomes more confident. With Hyperion's power, Percy has a new level of self - assurance. He's not as hesitant in battles or when making decisions.
A common theme is the power struggle. Hyperion being a powerful Titan and Percy Jackson having his own set of powers often leads to stories where they clash over power, territory, or the fate of the world. Another theme is the exploration of Percy's character growth in relation to facing an adversary as formidable as Hyperion. It's about how Percy overcomes his own limitations to stand against such a powerful foe.
One common theme is identity. Percy has to figure out who he is now as the son of Hyperion, different from his previous understanding of himself as Poseidon's son. Another theme is power. Discovering new powers and learning to control them is often explored.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of Percy Jackson and Hyperion fanfictions, with various themes and writing styles. Another option is Fanfiction.net, which also has a significant number of works in this genre. Just use the search function on these sites and type in 'Percy Jackson Hyperion' to find relevant stories.
Another interesting one is 'Hyperion's Heir: Percy Jackson'. In this, Percy not only has to face the challenges of being the son of Hyperion but also has to deal with the reactions of his friends and the wider demigod community. It's a long - form fanfiction that really takes its time to build up the story and develop the relationships between the characters.
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.
Obviously, Percy would be one of the main characters. Since it's Percy son of Hyperion, Hyperion himself might also play a major role, perhaps as a guiding figure or an antagonist. Other characters could include the friends Percy makes within this new context, like other demigods who are related to Hyperion's realm or have some connection to his new identity.
One implication is a change in his abilities. Elves are often associated with things like archery and nature magic, so Percy might gain these skills. His physical appearance would also change, probably getting pointed ears.
One implication could be that his relationships with other characters change. For example, his friends might be initially scared or cautious around him. His lycan abilities would also mean he has new powers to use in fights.
One interesting concept could be exploring Percy's relationships with other characters in a new light. Maybe his interactions with the children of Hyperion could lead to unique alliances or rivalries. Another concept might be delving into Percy's powers and how they could be enhanced or different in this fanfiction setting. For example, his connection to water could have some unexpected twists when combined with the influence of Hyperion.
