In a crossover with the Naruto universe, Naruto himself could be an ally. Naruto has a way of seeing the good in people, and he might try to reach out to Broly and convince him to use his power for good. His ability to befriend and understand others could be key.
One idea could be that Godlike Broly crosses over into the Dragon Ball Super universe and challenges Goku and Vegeta at their peak forms. His overwhelming power could force them to seek new power - ups and training methods.
In a crossover with One Piece, Luffy could be an ally. Luffy is known for his open - mindedness and ability to befriend almost anyone. He would see Broly's power and might try to get him to join his crew or at least fight alongside him against common enemies. They could have some really fun interactions, like Luffy trying to make Broly laugh or share his love for food with him.
One idea could be that Broly somehow ends up in the world of Black Lagoon. He might initially be seen as a huge threat by the Lagoon Company. But as the story progresses, they realize his power can be useful against their common enemies. For example, when facing powerful crime syndicates or military forces that are too much for them to handle alone.
Trunks would also be a great choice. Trunks is from the future and has a different set of skills and experiences. He could introduce Broly to some new technology or fighting techniques from his own timeline. And together, they could face threats that neither could handle alone, like a time - traveling villain.
Vegeta could also be an interesting choice. Vegeta has his own pride and issues with power, much like Broly. In a crossover fanfiction, they could start off as rivals, constantly trying to outdo each other in terms of strength. But as the story progresses, they might find common ground and have to work together against a common enemy. This would be a great way to explore both of their characters in more depth.
A third common theme could be the exploration of different universes. The fanfictions might delve into how the Dragon Ball universe, where Broly comes from, and the RWBY universe coexist or affect each other. This can include things like different laws of physics, magic systems, and cultural differences between the two universes.
A 'godlike Madara' in a crossover fanfiction could be really interesting. It might involve Madara from Naruto being given 'godlike' powers and then being crossed over into another universe, like a different anime or even a fictional world from a game. This could lead to some really epic battles and unique storylines.
Sure. You can try looking on websites like Archive of Our Own (AO3). There are often many crossover fanfictions there. Just search for 'broly rwby crossover' and you'll likely find a good selection.
A Broly crossover with the Naruto universe could be really cool. Picture Broly in the Hidden Leaf Village, his incredible power causing quite a stir. Maybe he could get involved in the fight against the Akatsuki, using his brute strength in a world of ninjas. It would be interesting to see how he adapts to chakra and ninja techniques.
