Power and transformation are common themes. Since it involves the Frieza race, there's often a focus on how characters gain new powers or transform into a Frieza - like state. Another theme is survival, as the Frieza race can be quite cruel and characters may need to fight for their survival.
An interesting plot could be that the OC is the last of the Frieza race after a great catastrophe. They are on a mission to rebuild their race but in a more benevolent way. However, other races are suspicious of their intentions, and they have to prove themselves worthy of trust.
A believable Frieza race OC can be created by adding depth to their relationships. They could have a mentor from another race who taught them different values. Their relationships with other Frieza race members can also be explored. Are they an outcast? Do they have friends within the race? By building these relationships and showing how they affect the OC's actions and decisions, the character will become more believable in the context of the fanfiction.
