If Gohan died in the Cell Games in fanfiction, it would be a game-changer. It could trigger new plotlines and character developments. Maybe Vegeta would have a change of heart or new allies would emerge to help the Z Fighters.
The story would likely take a very dark turn. Other characters might step up and try to fill Gohan's role, but it would be a huge challenge. It could also change the outcome of the Cell Games completely.
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.
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.
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 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.
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.
One possible storyline could be that Goku gets Ultra Instinct right when Frieza is about to kill all the Namekians. He then uses his newfound power to completely overpower Frieza and save the day. Another could be that he gets it during a battle with the Ginyu Force and easily defeats them all in one go.
