Some fanfictions also explore the idea of redemption for Sylar. Peter could play a role in this. He might be the one to show Sylar a different path. Their relationship then becomes about Sylar's journey towards redemption with Peter as a sort of guide or at least an influence. It's interesting how fanfiction can take these two characters and create so many different interpretations of their relationship.
In heroes fanfiction, a frequent storyline involves Peter and Claire exploring the limits of their powers. Since Peter can take on different powers and Claire can't be easily killed, they often put themselves in dangerous situations to test what they can really do. Also, there are storylines where they get separated from their group and have to rely solely on each other. This tests their relationship and their individual strengths. Moreover, there are plots where they encounter other characters with similar or opposing powers, which leads to interesting confrontations and alliances. They also sometimes face moral dilemmas related to their powers, like whether to use them for good or if there are any limits to using them at all.
In heroes fanfiction, Peter and Claire often have a complex relationship. They both have unique powers. Peter can absorb others' powers and Claire has the ability of rapid regeneration. Their relationship can be one of mutual protection. Peter may use his absorbed powers to keep Claire safe, and Claire's resilience can give her the courage to stand by Peter in dangerous situations.
One common theme is power exploration. Since both Peter and Claire have unique powers in the Heroes universe, fanfictions often explore how they can use, control, or combine their powers. Another theme is family. Given their complex family relationships in the original show, fanfictions may expand on how their family ties affect their actions and decisions.
Identity is also a common theme. Both characters have complex identities. Peter has the ability to absorb powers which can make his identity a bit fluid as he takes on different abilities. Sylar's identity is often tied to his search for more powers and his struggle with his own nature. Fanfictions might explore how their identities are shaped by their powers and their relationship with each other. Additionally, the theme of sacrifice could be present. Maybe Peter has to sacrifice something to stop Sylar, or Sylar might have to sacrifice his old ways to become a better person.
One common theme is brotherhood. Their relationship as brothers is often explored deeply, whether it's about loyalty, forgiveness, or protecting each other. For example, in many stories, they will put their lives on the line for one another.
One possible fanfiction could be about Claire and Peter teaming up to face a new, powerful villain. They could use their unique abilities - Claire's regeneration and Peter's power absorption - in creative ways to defeat the bad guy. For example, Peter could absorb the powers of other heroes they meet along the way to gain an edge in the fight, while Claire's ability to keep coming back from any injury would make her a great distraction.
A plotline could be that Peter loses his power - absorption ability. Claire then has to step up and protect him while they search for a way to get his power back. This would put a new dynamic on their relationship as Claire is usually the one being protected. It could also lead to some character growth for Peter as he has to rely on his wits and other non - power skills.
A very popular Peter and Claire heroes fanfiction is 'The Power Bond'. It shows how their powers are more connected than they initially thought. The story is filled with action scenes as they discover the extent of their power bond. There's also 'In the Shadows of Heroes' which is a darker take on their relationship. It explores how they deal with the darker aspects of their powers and the world around them.
Identity is also a big theme. Peter is a regular guy with superpowers in a modern - day city, while the Heroes of Olympus are demigods with a whole different set of responsibilities and backgrounds. The fanfictions often look at how they navigate their identities while being part of this new combined group. It can involve things like Peter dealing with the idea of being among literal gods and goddesses, and the demigods adjusting to a more 'human' superhero like Peter.
