One plot point could be that the male OC is a new recruit in Sephiroth's unit. He initially fears Sephiroth but gradually comes to understand him and they form an unlikely friendship.
Perhaps the male OC has a special power that Sephiroth is intrigued by. They start off as adversaries, with Sephiroth trying to either control or eliminate the OC because of his power. But as they interact more, they realize they have more in common than they thought. This change in their relationship from enmity to something more like comradeship or even a deeper bond can be the main focus of the fanfiction, exploring themes of prejudice, understanding, and growth.
How about 'The Encounter of Sephiroth and His Male OC Counterpart: A Fanfiction'. This title gives an idea that the story might be about how Sephiroth meets the male OC and what kind of relationship or interactions they will have. It also clearly states that it is a fanfiction which can attract the right audience who are interested in this particular pairing.
One great sephiroth x oc fanfiction is 'A New Bond'. It beautifully explores the relationship between Sephiroth and the original character. The OC in this story has a unique backstory that makes their interactions with Sephiroth very interesting.
A good plot point could be the student OC having a hidden power. Kakashi discovers this during training and is both curious and worried. He tries to help the OC control this power. This could lead to a series of training sessions where they get closer. Another plot point might be a rival who is jealous of the OC's relationship with Kakashi. This rival tries to create misunderstandings between them, which they have to overcome.
The plot is also crucial. It should not just be a simple love story but rather incorporate the rich lore of Final Fantasy. Maybe the OC is involved in the fight against the greater evil in the Final Fantasy universe, and Sephiroth plays a role in that struggle, either as an ally or an antagonist depending on the story's arc.
When writing a sephiroth x oc fanfiction, it's important to create a believable relationship. You can't just make them fall in love instantly. Build up the tension and the connection gradually. Consider the setting of the story as well. If it's in the world of Final Fantasy, make sure to include elements of that world. And always keep in mind the different arcs of Sephiroth's character. This way, your story will be more engaging and true to the essence of the characters.
In some male oc Vampire Knight fanfiction, a common plot point is the male oc being a new kind of vampire. For example, he might have powers that are different from the traditional vampires in the series. This can lead to him being both feared and desired by other characters. Another plot point could be the male oc getting involved in a love triangle with the main characters from the original story. It adds a new layer of drama and complexity to the relationships already present in the Vampire Knight world.
The most interesting plot point could be the clash of ideologies. Naruto, who stands for hope, friendship and protecting the weak, is a fan of Sephiroth, who represents power, destruction and self - centeredness. As Naruto tries to understand Sephiroth more, he starts to question his own beliefs. Does power always have to be used for good? Can someone as evil as Sephiroth have a redeeming quality? This internal struggle within Naruto, along with the external reactions of his friends and the ninja world, would make for a very engaging fanfiction.
Another aspect is the emotional side. The OC could be written to have a romantic or platonic attraction to Sephiroth. If it's romantic, it would add a whole new layer of complexity to their relationship, with love and conflict intertwined. And if it's platonic, it might be a friendship that challenges Sephiroth's view of the world and his place in it.
One common theme is redemption. Many fanfictions try to explore the possibility of Sephiroth finding redemption through his interactions with the original character. For example, the OC might show him a different way of life or values.
One plot idea could be a story where Cloud and Sephiroth are forced to team up against a new, even greater threat to the world. Maybe a powerful ancient entity awakens and they have to put aside their differences. Another idea is a more psychological exploration where Sephiroth tries to understand Cloud's unwavering will through some sort of shared dream - like scenario. Or perhaps a plot where Cloud has to save Sephiroth from a dark corruption that is taking over him, reversing their typical roles.
