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.
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.
In fanfiction, they often start as adversaries. Sylar being the power - hungry villain and Peter as the hero. But then their interactions can change. They might have intense power battles where they test each other's limits.
Some fandom - specific forums might also have Sylar and Peter fanfiction shared by the members. You could try searching for Heroes (the show they are from) related forums and see if there are any hidden gems there.

It shows a journey of Sylar struggling with his dark side and Peter guiding him towards the light. It's a very character - driven piece that explores their complex relationship in depth.
Some fanfictions might focus on a time - travel scenario. For example, Peter and Sylar are sent back in time and have to deal with their past selves. This could lead to interesting character developments as they see how they used to be and how they can change things for the better.
Another common theme is the exploration of their powers. Writers often create scenarios where their powers combine or conflict in unexpected ways. They might have to use their powers together to defeat a powerful villain or they could be in a situation where their powers are at odds with each other, like in a power - stealing scenario.

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.
