There might be some out there. However, Goku is mainly associated with his battles and his relationships in the official story are more about friendship and family. But in the world of fanfiction, anything can be re - imagined. You may have to dig deep into the different sections of fanfiction platforms to find such a story.
It could be really strange yet interesting. Maybe Goku, with his pure - hearted nature, somehow forms a deep connection with Oceanus Shenron. It might involve Goku seeing a different side of the dragon, not just as a foe but as a being with emotions.
Well, it's not really a fair comparison. Goku and Vegeta are from a universe where superpowers are the norm. They can destroy planets even. The toughest character in Pulp Fiction might be good with a gun or in a street fight, but against Goku's Kamehameha or Vegeta's Galick Gun, they wouldn't stand a chance. Goku and Vegeta are on a whole different level of power compared to the characters in Pulp Fiction.
Well, if they were brothers in a fanfic, it could change how they interact with the other characters. Maybe they'd have a deeper understanding and fewer power struggles between them. Also, their family background and upbringing could be explored in new and interesting ways.
It's a bit hard to say for sure. Both Vegeta and Goku have their moments of strength. Goku has some unique powers and techniques that give him an edge at times, but Vegeta is no slouch either and constantly works to catch up and surpass Goku.
Generally, Goku still holds the edge over Vegeta. Their power levels fluctuate, but Goku often achieves higher peaks of strength and unlocks more powerful forms first.
