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.
One popular Goku reader Namek fanfic could be 'Goku's Adventure on Namek'. It might involve Goku exploring the unique landscapes of Namek, interacting with its native species, and facing new challenges. Another could be 'Reader and Goku on Namek', which perhaps focuses on a self - inserted reader character joining Goku in his Namek - related quests, like searching for the Dragon Balls.
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.
You can try websites like FanFiction.net or Archive of Our Own (AO3).

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.
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.
