Well, a great concept is the exploration of new Saiyan planets in 'dbz oc saiyan fanfiction'. Since most Saiyans we know are from Planet Vegeta, an OC Saiyan could be from a different planet that was also part of the Saiyan empire. This would open up the possibility of different Saiyan cultures, power levels, and even different ways of achieving Super Saiyan forms. Also, the relationships these OCs have with their families, whether they are trying to avenge their lost families or build new ones, can be a very rich area to explore.
In 'dbz oc saiyan fanfiction', the idea of Saiyan OCs interacting with the main characters is really engaging. They could form alliances or rivalries. For instance, an OC Saiyan might train with Goku and learn from him, but also bring in their own fighting style which challenges Goku's techniques. It can also explore how these OCs fit into the Saiyan hierarchy and society, which was mostly destroyed but still has some remnants in the series.
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.
Another interesting concept is to cross them over with a fantasy world. Saiyans could be in a world full of magic and mythical creatures. Picture Vegeta having to deal with dragons that can talk and cast spells. Their Saiyan pride might get in the way at first when they realize that their brute strength isn't always enough in this new world.
Strength in the face of adversity is a frequent theme. These female saiyan ocs usually face many challenges, whether it's from other Saiyans, villains from other planets, or just the general difficulties of their situation. Also, the theme of loyalty, either to their Saiyan roots or to new friends and allies they make, is quite common. For example, in some fanfictions, a female saiyan oc has to choose between loyalty to her Saiyan heritage and the new values she has learned on Earth. This creates a lot of internal conflict and makes for an interesting story.
One interesting concept could be the idea of self - inserted characters having unique powers that interact with the existing DBZ power system. For example, a self - inserted character might have a power related to time manipulation in a world where the Saiyans' strength and energy blasts are the norm.
Some fanfictions focus on the idea of training in the Xenoverse. They might come up with unique training regimens for the characters. For example, a fanfic could have Vegeta training under a new master who has a completely different fighting style. This can lead to Vegeta developing new powers and techniques. Also, the concept of a new threat to the universe that is not related to the usual villains in Dragon Ball Z can be exciting. It forces the characters to adapt and find new ways to fight.
In dbz gamer fanfiction, an interesting idea is the introduction of new races or characters inspired by gaming tropes. They could have unique abilities that interact with the existing DBZ powers, creating fresh and unexpected storylines.
Another concept is the interaction between Saiyan and RWBY characters. Maybe a Saiyan could train with the students at Beacon Academy. This would bring in a whole new training regime. The Saiyan's intense training methods like high - gravity training could be introduced to RWBY characters, and in turn, the RWBY characters could teach the Saiyan about Aura and Semblance.
Well, 'Saiyan Heart' is a really interesting dbz female saiyan oc fanfiction. In this story, the female saiyan oc has a special bond with the Earth and its people. She uses her Saiyan strength in new ways to protect the planet. There's also 'The Forgotten Saiyan', which is about a female oc who was lost in space but returns to the Saiyan world with newfound abilities and a different perspective on her heritage.
In 'dark naruto dbz fanfiction', the exploration of dark versions of characters is likely. Like a dark Naruto who has turned to the dark side due to some extreme circumstances. He could have powers that are a twisted version of his normal ones and his goals might be more self - centered and malevolent.
In DBZ and Justice League fanfiction, a common concept is the idea of training together. For instance, the Saiyans could teach the Justice League members how to harness their ki. This could lead to new power - ups for the Justice League characters. Another aspect is the exploration of different moral codes. The Saiyans have a different view on combat and honor compared to the Justice League. Fanfiction can delve into how these two groups might influence each other's perspectives. There could also be a story where the villains from both universes team up, forcing the heroes from DBZ and the Justice League to combine their forces to stop them.
