Yes, there are quite a few out there. You can start by looking on fanfic websites like FanFiction.net or Archive of Our Own. Just search for 'DBS Goku x Bulma' and you'll likely find some interesting reads.
One factor is the exploration of their relationship in different scenarios. In the canon, they have a long - standing friendship. Fanfics can take this and expand it, like what if Goku developed romantic feelings for Bulma? Or how would they handle a crisis together in a more intimate way than in the show? Also, seeing how the authors incorporate the Dragon Ball Super elements like the new forms and powers into the story of their relationship adds depth and interest.
A possible plot could involve Goku and Gine meeting in a parallel universe where the normal rules don't quite apply. They start off as strangers but quickly realize they have a lot in common. Their relationship could develop as they train together, learning from each other's fighting styles. Gine might introduce Goku to some unique Saiyan traditions that have been long forgotten, and together they become a powerful duo in this new universe.
Boruto's ninjutsu like the shadow clones could be used in creative ways in combination with Goku's attacks. For example, the shadow clones could distract an enemy while Goku charges up a Kamehameha. Goku's ki - based attacks could also enhance Boruto's Rasengan, perhaps by adding a ki - infused shell around it. Boruto's ability to sense chakra might be affected by Goku's intense ki, and he could learn to use it to his advantage, like sensing enemies from a greater distance.
In a fanfiction scenario where Boruto Uzumaki meets Goku, there could be an exchange of combat techniques. Goku might be intrigued by Boruto's ninja skills like the Rasengan. Boruto, on the other hand, would be in awe of Goku's Super Saiyan forms and godly ki. They could potentially team up against a common enemy, perhaps a new powerful villain created just for this fanfic. Goku's vast experience in fighting powerful foes could teach Boruto a lot about battle strategy and power control.
Sure. There could be a great potential. They could be portrayed as comrades in a fight against a common enemy. Their combined Saiyan powers could be a major factor in the story.
