Maybe the Saiyan male OC is an outcast in his own clan. He discovers Kale while she is in her Berserker form. Instead of being afraid, he is intrigued and tries to communicate with her. This leads to a unique bond where he helps her control her power. In the fanfiction, their relationship could be a slow - burn one, with the OC gradually showing Kale the beauty of their Saiyan heritage and how she can use her power for good without losing herself to the Berserker side.
One idea could be that the Saiyan male OC is a warrior from a different part of the Saiyan planet. He meets Kale during a universal tournament. At first, Kale is shy and reserved around him, but as they train together for the next rounds of the tournament, they start to develop feelings. The OC could teach Kale some new Saiyan fighting techniques that she hasn't seen before, which helps her gain more confidence in herself not just as a fighter, but also in her relationship with the OC.
The Saiyan male OC could be a time - traveler. He comes from a future where Kale has already become a great hero. When he travels back in time and meets her, he decides to help her reach her potential faster. Their relationship develops as he trains her and protects her from the threats that come their way. They face challenges together, like dealing with the other Saiyans who might not trust the OC because of his mysterious origin, but they overcome them through their love and determination.
The Saiyan male OC can be developed by giving him a moral code. For instance, he might believe in always fighting fair and never using dirty tricks. This can contrast with Kale who, in her Berserker state, might not be as in control. As for Kale, you can develop her character by showing how she adapts to new situations. When the OC introduces her to new Saiyan traditions or places, how does she react? Does she embrace them or is she hesitant? Their characters can grow as they influence each other. The OC can inspire Kale to be more confident in her normal state, and Kale can teach the OC about the raw power that lies within a Saiyan when pushed to the limit.
One idea could be to create a male OC who is a skilled mechanic. He could start off as an ordinary worker in one of the Gundam 00 facilities. But then, through a series of events, he discovers a hidden ability within himself related to the Gundam technology. Maybe he can communicate with the Gundam on a deeper level than anyone else. This could lead to him being recruited into a special team that deals with high - risk missions. He would have to face challenges not only from the enemies but also from within the team as some might be jealous of his new - found abilities.
There are several common plots. For instance, the Saiyan OC male might be part of a team of warriors. They go on various missions together, and he has to learn to work with others, which is a challenge for the often - proud Saiyans. Another plot could be that he discovers a hidden Saiyan legacy. This could involve finding ancient Saiyan artifacts or learning about a long - lost Saiyan technique that changes his life and the course of the story.
First, focus on his physical traits. A Saiyan male is often strong and muscular. Give him a unique hair style, like the spiky Saiyan hair but with a different color perhaps. Then, think about his personality. He could be proud like most Saiyans, but also have a soft side. For example, he might be kind to his friends but still eager to prove his strength in battles.
One idea could be to have the male OC be a gamer in the real world who gets transported into the Naruto universe. He could use his gaming skills, like strategic thinking and quick reflexes, to adapt to the ninja world. For example, he might be really good at predicting opponents' moves in games, which would help him in battles against ninjas.
One idea could be to have the male OC reincarnated as a powerful shinobi from a forgotten clan. He could have unique abilities that set him apart from the regular Naruto characters. For example, he might be able to control a new type of chakra nature that no one has seen before.
One idea could be to create a male OC who is a fellow soldier in Shang's army. He could start as a bit of a rival to Shang, competing for the best combat skills or leadership positions. For example, he might be from a different region with a unique fighting style. As the story progresses, they could learn from each other and form a strong bond, especially during a difficult battle where they have to rely on each other's strengths.
A more comical fanfiction could be about Kale trying to adapt to the food in the Naruto world. Naruto could introduce her to ramen, and she might have some really funny reactions, while also sharing some Saiyan cuisine with Naruto and his friends.
Another interesting concept is a Saiyan OC who is a hybrid with another alien race. This could lead to some really cool character design and powers. They could struggle with fitting in among both Saiyan and the other alien culture, adding depth to their story.
