One possible title could be 'Itachi Uchiha and the Unseen Bond with the OC'.
There's also 'The OC's Journey with Itachi'. This fanfiction focuses on how the OC's presence changes Itachi's perspective on certain things. The writing style is captivating, and the author does an amazing job of creating a believable relationship between Itachi and the OC. It has some really heart - warming moments.
First, you should focus on Itachi's character traits. His calm and calculating nature, his loyalty to his clan despite the difficult decisions he had to make. For the OC, give her (or him) a unique backstory that can connect with Itachi's world. Maybe the OC has a special power that Itachi notices.
A good Itachi Uchiha x OC fanfiction often has a well - developed OC. The character should have a distinct personality, backstory, and goals. For example, an OC with a strong moral code that clashes or complements Itachi's own values can create interesting dynamics. Also, staying true to Itachi's character from the original Naruto series is crucial. If he's written out of character, it can ruin the story.
One idea could be a story where Itachi and Kushina meet in a parallel universe. In this universe, the events of the original Naruto storyline are altered, and they end up on the same side, fighting against a new common enemy. Their unique abilities, Itachi's Sharingan and Kushina's powerful chakra, would make for an interesting combination in battles.
One common theme is friendship. Since Itachi is such a complex and interesting character, many fanfictions explore how an OC can form a deep and meaningful friendship with him. For example, they might bond over their shared love for the village or a mutual understanding of the sacrifices one has to make in the ninja world.
Another concept could be a story where the magic in the Harry Potter world and Itachi's ninjutsu are somehow combined. Imagine Itachi using his fire - style jutsu along with a spell from the Harry Potter world to create a unique and powerful attack. This could be used against a common enemy that threatens both the ninja world and the wizarding world.
One possible title could be 'Scarecrow and My OC: An Unlikely Bond'.
A simple yet effective title could be 'Percy x OC: A Fan - Created Story'. It clearly states what the fanfiction is about, that it involves Percy and an original character, and that it's a story created by a fan.
Some possible titles could be 'Mitsukuni and My OC: An Unlikely Bond', 'The Encounter of Mitsukuni and My OC', 'Mitsukuni's Adventure with My OC'.
One possible title could be 'Crowley and the Mysterious OC: An Unlikely Bond'.
