The male OC could have a unique backstory that ties him to a part of the Dragon Ball Z universe that hasn't been explored much. Maybe he was raised in a dimension where time moves differently. As a result, his perception of time and space is different from others, and he can use this to his advantage in combat, confusing his opponents with his unorthodox maneuvers.
By having a unique power source. For instance, instead of relying on ki like most characters, he could draw power from the spiritual energy of nature. This would make his power different in appearance and function. He might be able to heal the planet as he battles, using the planet's own energy to boost his attacks.
A male OC can stand out by having a distinct personality. If he is a pacifist at heart but is forced into battles, his internal struggle could be very interesting. He could try to find non - violent solutions to conflicts first and only use his powers when absolutely necessary. This would be a contrast to the more battle - hungry characters in Dragon Ball Z.
An OC can stand out by having a unique power. For example, a power that is not based on ki but on something else like the power of sound. They could use sonic blasts or create illusions with sound waves. This would be different from the typical ki - based attacks in Dragon Ball.
The unique character of Erasa. In fanfiction, she can be developed in ways that the original series didn't fully explore. For example, her relationships with other characters can be expanded upon, like her friendship with the main characters. Also, the fanfiction can give her a more active role in battles or adventures.
A great Frieza fanfiction often has a unique take on his character. Maybe it delves deeper into his backstory, like exploring his upbringing on Planet Frieza. This can add new dimensions to his already complex personality.
To make it stand out, give your OC some distinct abilities. Since they are a gamer, it could be something like being able to analyze an opponent's moves in real - time like reading the code in a game. Also, use detailed descriptions of the battles. Instead of just saying they fought and won, describe how they used their gamer - like reflexes and skills. For instance, they might dodge an attack by predicting it like they would in a fighting game. Incorporate references to different Dragon Ball games, shows, and manga to make it more appealing to fans of the franchise.
First, develop your OC really well. Give them a unique backstory, personality, and powers. For example, if your OC has a power related to emotions, it's something new in the Dragon Ball world. Second, don't just focus on the harem aspect in a clichéd way. Show real relationships developing. Third, add some twists to the Dragon Ball canon. Maybe your OC has a connection to an ancient prophecy that changes the course of events.
Another idea is a male OC who is a master of an ancient martial art that has been lost in the Dragon Ball Z universe. He could use this martial art to defeat enemies in unexpected ways. His fighting style might focus on using the opponent's energy against them, rather than relying solely on his own power.
One way to create a Frieza Race OC for Dragon Ball Z fanfiction is to first think about their physical appearance. They could have the signature purple skin, white horns, and long tails like Frieza. For their personality, maybe they're more cunning and strategic than the average Frieza Race member. They could be an outcast who doesn't agree with the cruel ways of their race and is secretly trying to find a way to change their people's nature. Their power level could start off relatively low but through various adventures in your fanfiction, they grow stronger and learn new techniques.
The harem aspect should be developed in a way that doesn't feel forced. Each relationship in the harem should have its own story arc. In a Naruto x Dragon Ball Z harem fanfic, the different cultures of the two series can play a big role. If the fanfic can explore how a character from the Naruto world would adapt to the more alien - like Dragon Ball Z world when it comes to relationships, it can be really engaging. Also, having unique plotlines that are not just a rehash of the original series plots is key.
First, create a well - developed character. Give your female OC a unique backstory. For example, if she's a Saiyan, explain how she survived the destruction of Planet Vegeta differently from Goku. Then, make her personality distinct. Is she hot - tempered like Vegeta or more laid - back like Goku? Next, integrate her into the existing Dragon Ball Z world. Have her meet the main characters in a believable way. Maybe she crashes on Earth during a fight in space. Also, give her a goal or motivation. It could be something like avenging her family or finding a way to become the strongest in the universe.
First, know the Dragon Ball Z universe well. Understand the powers, the races, and the existing storylines. This knowledge will help you create a believable SI OC. For example, if your OC has a power that's too overpowered without any explanation, it won't fit well.
