In the 'bardock sees goku as a god' fanfiction, a plot development could be that Bardock's belief in Goku as a god gives Goku new powers or a new level of confidence. This could lead to Goku taking on more dangerous foes. Or perhaps Bardock tries to build a temple or shrine for Goku. There could also be a conflict where some villains try to use Bardock's blind faith in Goku to their advantage by tricking him into leading them to Goku.
Well, it could make Bardock more in awe of Goku. He might see Goku as an untouchable being now. This could lead to a more distant relationship at first, as Bardock may feel unworthy to be close. But over time, he could also become a very devout follower or protector of Goku in a new way.
At first, it might be tense. Bardock is a hardened Saiyan warrior from a different era, and Goku has grown up on Earth with a very different set of values. But as they start to communicate, they would find common ground in their Saiyan blood. Goku's pure - heartedness could gradually win over Bardock, and Bardock's strength and pride could earn Goku's respect.
At first, it could be a bit rocky. Bardock is used to the harsh Saiyan ways, while Goku has been raised on Earth with different values. But as they spend time together, they start to understand and respect each other. Bardock could become a mentor to Goku, teaching him advanced Saiyan fighting techniques and Goku could teach Bardock about friendship and love.
One possible interaction is that Bardock could spar with Goku and Gohan. He'd test their limits and see how much they've learned about fighting. Another could be Bardock sharing stories of Planet Vegeta with them, which would be really interesting for Goku and Gohan to hear.
He could meet his descendants like Goku or Vegeta. It would be an interesting encounter as they have different upbringings and personalities compared to Bardock.
Well, it could be about a lot of things. Maybe it's a fan - created story where Chilled, Bardock, and Goku are all involved in some sort of adventure or conflict. It might explore their relationships, like perhaps a scenario where Goku has to face off against Chilled while Bardock's legacy or influence somehow plays a part.
It could change it a great deal. Goku might learn more about his Saiyan roots earlier, which could potentially make him more in tune with his Saiyan side. This could lead to him training differently or having different goals. For example, he might be more interested in exploring his Saiyan heritage and what it means for his power - up potential.
Another theme is power transfer or inheritance. Some fanfics might have Bardock passing on some hidden power or knowledge to Goku. This could be related to their Saiyan abilities or some special technique that only their family line can access. There is also the theme of redemption in some cases. If Bardock is brought back in a fanfic, he may seek to atone for his past actions through his relationship with Goku.
