One idea could be that Bardock, after somehow escaping the destruction of Planet Vegeta, lands on Namek. He then meets a young Namekian who is curious about his Saiyan powers. Bardock could start training this Namekian, passing on some of his combat skills.
In a fanfic of Bardock arriving on Namek, he could land in the middle of a conflict between different Namekian tribes. Bardock, with his warrior skills, might get involved and try to bring peace. He may also find that the energy on Namek is different from what he's used to and has to adapt quickly. His arrival could also set off a chain of events that changes the future of both the Saiyans and the Namekians.
Well, it could be about Bardock arriving on Namek before the Saiyans' destruction. Maybe he teams up with the Namekians against some common enemy. He could use his Saiyan strength and battle instincts to help protect the Namekian villages.
In the fanfic, Bardock arriving on Namek could lead to a change in the power dynamics. He could train with the Namekians and learn their unique techniques. This new knowledge combined with his Saiyan strength would make him an even more formidable opponent. And perhaps, his presence could inspire the Namekians to be more proactive in defending themselves against external threats.
In the fanfic, Bardock might find a connection between the Saiyan and Namekian races that was previously unknown. There could be an ancient prophecy on Namek that mentions the Saiyans, and Bardock's arrival could be seen as the start of the fulfillment of that prophecy. This could lead to a whole new set of adventures and alliances for him.
If Bardock arrives on Namek in the fanfic, it could also change the fate of the Dragon Balls. Instead of being just a tool for Frieza or the Z - fighters to use, Bardock could have a different vision for them. He might see them as a way to not only save Namek but also to restore the Saiyan race. This would open up a whole new set of plotlines and possibilities, as his motives would be different from the other characters who have interacted with the Dragon Balls in the original story.
A possible plot for a Bardock x Fasha fanfic is that they are both chosen for a special training program. During this training, they face various challenges that test not only their physical strength but also their relationship. They might start as rivals in the program but gradually realize their mutual attraction. Or perhaps they are sent on a rescue mission where they discover new things about each other and their Saiyan heritage.
A possible fanfic could involve Towa and Mira trying to manipulate the events of the Cell Games for their own gain. They might see Cell as a powerful weapon or an opportunity to disrupt the timeline further. Bardock, on the other hand, could be the wildcard who tries to stop their evil plans. He might have a moral compass that is different from the other villains and decides to protect the innocent, especially since he has a connection to Goku.
One idea could be to focus on Bardock's perspective before his fateful battle. Maybe explore his thoughts about his son Goku being sent to Earth and his own impending doom. He could have some premonitions about Goku's future role in saving the universe.
One idea could be that Naruto realizes his feelings for Anko during a mission. Maybe they are stuck together in a dangerous situation and he sees a different side of her. This makes him start to think about a future with her.
One possible plot could be Bardock getting trapped in a Xenoverse where the rules of time and space are different. He has to find a way to get back to his own universe while facing off against powerful enemies.
