One interesting plot could be that when they time travel, they end up in a time before the Uchiha massacre. Itachi could then try to change things with Naruto's help, and in the process, their relationship deepens in a yaoi way. Maybe Naruto helps Itachi see a different path for the Uchiha, and they grow closer as they face the challenges together.
One great 'Naruto x Itachi Time Travel Fanfiction' is 'A New Chance'. It offers a unique take on how Naruto and Itachi's relationship could change if they traveled through time. It delves into their past traumas and how they might be able to prevent some of the tragedies that occurred in the original story.
The theme of mutual understanding also prevails. Naruto and Itachi come from different generations and have had very different experiences. In the yaoi fanfiction, they learn to understand each other on a deep level. They share their pain, their dreams, and their fears, which helps in strengthening their bond. This is often shown through long conversations and shared moments of vulnerability.
The contrast between Itachi and Naruto's characters makes it interesting. Itachi is often seen as a complex and mysterious figure, while Naruto is the bright and determined protagonist. Their different personalities and life paths can create a lot of tension and unique storylines in yaoi fanfiction.
One common theme is redemption. Itachi has a lot of guilt in his past, and in these fanfictions, Naruto can often be the one to help him find redemption. For example, Naruto's belief in people's good nature can make Itachi see himself in a new light.
Naruto would likely become more understanding of Itachi's past and the sacrifices he made. His view of the Uchiha clan and the concept of loyalty would be broadened. For Itachi, being with Naruto during the time travel might make him more open about his emotions. He would start to rely on Naruto not just as a comrade but also as someone he has deeper feelings for.
One idea could be that during their time travel, Naruto and Itachi end up in a time when the Uchiha clan was not massacred yet. Itachi has to face his past self and Naruto tries to find a way to prevent the tragedy without changing too much of the future. Another plot could be that they travel to a future where everything is in chaos and they have to use their combined skills and new - found relationship to set things right.
Another theme is redemption. Itachi, in particular, has a lot of room for redemption arcs in these fanfictions. His actions in the original series can be re - examined and re - shaped in the context of his relationship with Naruto and Sasuke. Also, friendship evolving into something deeper is a big theme. Naruto and Sasuke's friendship is a central part of the original Naruto story, and in these yaoi fanfictions, it can take on new dimensions when Itachi is added to the mix. They all support and challenge each other, which is a recurring idea in many such fanfictions.
Time travel might put them in situations where they are forced to depend on each other more than ever. If they end up in a dangerous time period, they'll need to trust each other completely. This can intensify their yaoi relationship. They might have to share their innermost thoughts and feelings to survive, which would bring them closer together on an emotional level.
I'm not sure if there is such specific fanfiction readily available. Fanfiction websites vary greatly in their content, and this type of rather niche and often inappropriate (due to the yaoi lemon aspect which may involve adult content) combination might not be easy to find on mainstream or family - friendly platforms. However, there could be some on less - regulated or more specialized fan - created platforms, but exploring such might expose you to content that violates ethical or community standards.
