One common theme is power struggle. Since Frieza is a powerful villain in DBZ, when a male OC is introduced, there's often a struggle for power or dominance. For example, the OC might have powers that rival Frieza's and they constantly test each other.
One great fanfic could be 'Frieza's New Ally'. In this story, the male OC has unique powers that catch Frieza's attention. The OC starts as a reluctant partner to Frieza but gradually they form a complex relationship. It has some really exciting battle scenes where the OC's powers are put to the test against other DBZ characters.
One good 'DBZ Frieza x OC fanfiction' could be where the OC is a powerful being from a far - off planet and catches Frieza's interest. The OC might have unique powers that Frieza wants to use for his own gain, leading to an interesting power struggle and relationship development. For example, the OC could have the ability to control time, and Frieza tries to force the OC to use it for his galactic conquests.
First, you need to create a well - developed OC. Decide on their appearance, personality, and backstory. For example, if your OC is a warrior, think about what made them become a warrior. Then, consider Frieza's character. He is power - hungry and cruel. Think about how your OC would interact with such a character. You could start with a scenario like the OC being captured by Frieza's forces.
One concept could be an OC Frieza Race character who rebels against the tyrannical ways of Frieza. This character might have grown up seeing the cruelty of Frieza's rule and decides to use their powers for good. They could secretly help the oppressed races in the DBZ universe, like the Namekians or the Earthlings.
Give them a sense of humor. For example, they could have a dry, sarcastic wit that is unexpected for a Frieza Race. This would set them apart from the typical cold and menacing Frieza Race characters. They might make snarky comments during battles or when dealing with other characters.
One good dbz x oc fanfiction could be 'The New Saiyan'. In it, the OC has unique powers that interact in interesting ways with the DBZ characters. It's full of action and adventure.
For Frieza, the news of the pregnancy could make him more protective. He might start to see the OC in a new light, not just as a subordinate or a conquest. His character could shift from being purely evil to having some redeeming qualities as he anticipates fatherhood.
Perhaps the OC was sent to spy on Frieza but instead falls in love with him. The pregnancy then becomes a complication as their respective races have different views on inter - species relationships. This could create a lot of drama and tension in the fanfiction, with both characters having to fight for their love and the future of their unborn child.
Since the term is rather unclear, it's hard to define specific characteristics. But generally in Frieza - related fanfiction, one might expect elements of power struggles as Frieza is a very powerful character in the Dragon Ball universe. If there's an original character (OC), there could be interactions that either challenge or complement Frieza's nature.
