Another theme is power and growth. The OC usually has some unique power or ability. Their interactions with Sasuke lead to both of them growing in terms of power. This could be in combat skills or in understanding the complex nature of the ninja world. For instance, they might face a powerful enemy together and in the process, both Sasuke and the OC become stronger and more well - rounded characters.
One common theme is redemption. The oc often helps Sasuke find a way to redeem himself, either from his past actions or his inner turmoil. For example, in many stories, the oc's presence makes Sasuke question his thirst for revenge.
One common theme is self - discovery. The original characters often have to figure out their place in the Naruto Shippuden world. Another is friendship, as they interact with the known characters. And power - up is also common, like the oc developing a new jutsu or getting stronger in some way.
One great OC could be a female ninja named Aya. She is strong - willed, has amazing combat skills, and is not afraid to stand up to Sasuke. Her determination and loyalty make her an interesting character in the fanfiction. Another could be Kai, a male OC who has a unique ability to control the elements in a different way than the known ninja in the Naruto universe. His different perspective and skills make him stand out when paired with Sasuke.
Love and relationship development is also very common. Many fanfictions focus on how Sasuke and Sakura finally get together. It could start from small glances and shared memories, and then gradually build into a full - fledged relationship. Some might include some jealousy plotlines as other characters are interested in either Sasuke or Sakura.
One great 'naruto shippuden sasuke x oc fanfiction' is 'The Uchiha's New Path' where the OC has a unique connection with Sasuke that changes his journey in interesting ways.
One common plot could be the OC being a powerful ninja from a different village who meets Sasuke during his journey in Shippuden. They start off as rivals but gradually develop feelings for each other as they face common enemies together. Another plot might involve the OC having a special ability that is crucial in helping Sasuke achieve his goals, and through their interactions, a romantic bond forms. Or perhaps the OC is on a mission to redeem Sasuke and in the process, they fall in love.
One common trope is the 'outsider who understands'. The OC is often an outsider in some way, whether it be from a different village or having a unique power, but they seem to understand Sasuke on a deeper level than others. Another is the 'love - against - all - odds' trope. Since Sasuke is a complex and often aloof character, the OC usually has to overcome many obstacles to get close to him.
A prevalent theme is redemption. Sasuke has a complex past, and in these fanfictions, his relationship with the OC can be a part of his journey towards redemption. Also, the theme of acceptance is quite common. They have to accept their feelings for each other, especially considering the nature of yaoi relationships in the Naruto - inspired setting.
Romance is, of course, a big theme. Writers usually explore the relationship between the reader and Suigetsu, whether it's a slow - burn romance or a more immediate attraction. Another theme is self - discovery. As the reader character interacts with Suigetsu, they often learn more about themselves and their own abilities in the Naruto world.
The theme of sacrifice also shows up a lot. Both Naruto and Sasuke are characters who are willing to sacrifice for the other in the original story, and this is often explored further in fanfiction. Writers might create scenarios where one has to make a big sacrifice for the other, which then tests and deepens their relationship.
