Well, they might start off as rivals. Vegeta could be initially dismissive of young Goku's power. But as the story progresses, they could end up teaming up against a common enemy, like Frieza perhaps. And along the way, Vegeta could learn some valuable lessons about humility from Goku.
In a 'Vegeta meets Chibi Goku' fanfiction, it could be really fun. Chibi Goku might be curious about Vegeta's Saiyan pride and constantly ask him questions. Vegeta would probably get annoyed at first but gradually warm up to the little guy. They could also have some training sessions together, with Vegeta trying to teach Chibi Goku some of his more advanced techniques, and in the process, they become friends who respect each other's abilities.
One interesting plot point could be that Vegeta initially mistakes young Goku for a weakling because of his small stature. But when Goku shows his incredible strength in a fight, Vegeta is forced to re - evaluate his assumptions.
Goku could escape by overpowering Broly. He might tap into his Super Saiyan forms, like going into Super Saiyan Blue or even Ultra Instinct if he's pushed far enough. His sheer power and fighting skills could allow him to break free from whatever restraints Broly has put on him.
Sure. Fanfiction writers have a lot of creative freedom when it comes to Goku and Female Broly. In some fanfictions, they might be in a romantic relationship, which is an interesting take considering their Saiyan heritage and the way they both value strength. However, not all fanfictions take this route. Some might explore a more platonic friendship where they respect each other's power and learn from one another. You can usually find a variety of these stories by using the search function on major fanfiction platforms.
Yes, in the vast world of fanfiction, there are all kinds of creative and out - of - the - box stories. Some fans like to explore unusual relationships and scenarios, so it's possible that there is such a fanfiction out there. However, it goes against the original canon of the Dragon Ball series in many ways.
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.
