For a Beerus OC in fanfiction, it could be an OC who was once a normal cat - like creature on a destroyed planet. Beerus, out of pity or some unknown reason, bestowed some of his power on this creature. As a result, the OC gradually evolved into a powerful being with some of Beerus's characteristics. This OC could have a very different personality from Beerus, being more kind - hearted and using their power to help revive planets rather than destroy them.
One idea could be an OC with a unique ki ability that no one in the Dragon Ball Z universe has seen before. For example, the ability to transform into an energy form that can pass through solid objects. Another plot could involve an OC who is from a long - lost race in the Dragon Ball Z lore and has to find their place among the Saiyans, Namekians, etc. A third idea might be an OC who is a time - traveler and has to prevent a major catastrophe in the Dragon Ball Z timeline.
One idea could be an OC with a unique power that can nullify the energy of any attack, which throws off the Saiyans' fighting strategies. Another could be an OC who is a master of a long - forgotten martial art that gives them an edge in battles against the Z - fighters. Maybe an OC who has a connection to an ancient and powerful race that even the Kais don't know much about.
Power is a common theme. Since Beerus is extremely powerful, many fanfictions explore his power, how he got it, and how he uses it. Another theme is his relationship with other characters, like Goku. Some fanfictions also focus on his role as a God of Destruction, the responsibilities and the consequences of his actions.
There are 'Dragon Ball Z OC Fanfiction' where the OC is a non - Saiyan but has a special connection to the Dragon Balls. For example, an OC who is a wizard from a far - off planet. This wizard could use magic in ways that blend with the ki - based combat of Dragon Ball Z. They might be on a quest to protect the Dragon Balls from an evil force that wants to misuse their power for world domination.
One interesting 'Dragon Ball Z OC' fanfiction story could be about an OC who has a unique power that they discover during a battle against a new enemy. For example, an OC might have the power to manipulate time in a very limited way, like slowing down an opponent's attack just enough to dodge. Another could be an OC that is from a different planet but has a connection to the Saiyans. This OC could bring new knowledge about Saiyan history or abilities that were previously unknown.
Well, for 'Ben 10 Dragon Ball Z fanfiction', a cool concept could be that Ben gets caught in a time - space rift that sends him to the Dragon Ball Z universe right when a new and powerful enemy is emerging. Ben has to quickly figure out how to use his Omnitrix in this new world while also trying to get back home. And perhaps some of the Dragon Ball characters are intrigued by the Omnitrix and want to study it, leading to some funny and interesting interactions.
Another interesting concept would be Shallot getting lost in a different dimension within the Dragon Ball Z universe. He would have to find his way back while encountering strange new races and powers, and along the way, he might learn some valuable lessons about himself and his abilities. This could lead to him coming back to his own world as a much stronger and wiser fighter.
Some ideas for Dragon Ball Z Gine fanfiction include a time - travel story. Gine could be brought to the present day by some time - traveling villain or device. Then she has to adapt to the new world while also using her Saiyan knowledge and skills to help the Z - fighters. Another idea is to focus on Gine's family. Write about her relationship with Bardock in more depth, or create a story about her extended family on Planet Vegeta that we haven't seen before. You could also do a story where Gine meets the other Saiyans who were resurrected, like Nappa and Raditz, and how she interacts with them.
One idea could be a fanfiction where Vegeta gets a completely new haircut as a part of a disguise during a mission on a new planet. Maybe he has to blend in with the locals who have a very unique and flamboyant hairstyle. Another could be about Goku getting his hair cut by Chi - Chi because she wants him to look more presentable for a family gathering, but then he discovers that his power level is affected in some strange way. And a third idea might be a story where Trunks experiments with different haircuts to impress a new love interest in his timeline.
A great fanfiction idea could be about the Dragon Balls being accidentally transported to the Naruto universe. This would cause chaos as various ninja clans try to get their hands on them for different reasons. Maybe Naruto himself would be the one to discover them first and he has to figure out how to use them or protect them from those with malicious intent. And of course, there could be some fun interactions between Naruto's friends and the Dragon Ball Z characters who come looking for the balls.
