Common themes include the idea of changing the course of the Naruto story. With Naruto being related to Tobi in some way in these fanfictions, it can lead to different outcomes for the ninja world. For example, they could team up against a greater threat that wasn't in the original plot. There's also the theme of uncovering secrets, as Tobi has many secrets, and Naruto could be the key to revealing them all.
Another common theme might be the idea of secrecy and forbidden love. Given that yaoi involves same - sex relationships and in the Naruto world, which is more focused on traditional ninja relationships, their relationship could be seen as something that has to be hidden. This can add an element of tension and drama to the fanfiction. There could also be themes related to personal growth for both characters as they navigate their relationship.
One common theme is power exploration. Since Tobi has unique powers, in crossovers, writers often explore how his powers compare and interact with the powers in the other universe. For example, in a crossover with the Dragon Ball universe, his stealth abilities might be pitted against the ki - sensing abilities of the Saiyans.
Love and friendship are also common themes. Some stories explore the budding romance between the reader and Tobi, how they fall in love despite the challenges. Friendship is also there, like when the reader becomes Tobi's closest confidant. Additionally, there can be themes of redemption. If Tobi has done some bad things in the original story, the fanfiction might show how the reader helps him redeem himself.
The theme of redemption is also seen quite a bit. Tobi may have made mistakes in the past, but through love, he is able to redeem himself. It gives the story a positive and hopeful tone, showing that love can be a powerful force for change.
Often, there are themes of self - discovery. Sakura and Tobi may each be on a path to learn more about themselves and their powers or abilities. Also, themes of mystery can be present. For example, there could be a mystery surrounding Tobi's true identity that Sakura helps to uncover. And sometimes, there's a theme of redemption, where one of the characters has made mistakes in the past and is trying to make up for it through their relationship with the other.
One common theme is redemption. Since Obito has a dark past in the Naruto series, in many fanfictions, the OC helps him find a path to redemption. Another theme is love against all odds. Their relationship often has to overcome obstacles like Obito's loyalty to his original goals or differences in their villages.
One possible theme could be the clash of their different personalities. Tobi is often mysterious and has his own agenda, while Naruto is known for her determination and positive attitude. Another theme might be the exploration of power dynamics between them, as they both have different levels and types of power in the Naruto universe.
One common plot point is the revelation of Naruto's true parentage. Usually, there's a big moment where it's disclosed that Tobi is his father, which causes a stir in the ninja world. Another is Naruto inheriting some of Tobi's unique abilities or knowledge. For example, he might gain some special jutsu related to Tobi's powers.
One interesting Naruto and Tobi fanfiction could be where Tobi reveals his true identity to Naruto earlier in the story. This would completely change the course of events and their relationship. Naruto might try to reason with Tobi, believing there is still good in him.
