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.
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.
One idea could be that Broly ends up in an alternate universe where he has to team up with Goku and the Z - fighters to fight a new, even more powerful enemy. This would force Broly to control his anger and work with his former foes.
Goku and Captain America. Goku is all about pure power and his simple - minded pursuit of getting stronger. Captain America, on the other hand, represents honor, leadership, and strategy. The contrast between them would be fascinating. Goku could learn about leadership from Cap, and Cap could be inspired by Goku's unwavering determination to keep getting stronger.
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.
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.
Goku could be a likely ally. Despite their initial conflicts, Goku has a way of seeing the good in people. He might approach Broly and convince him that they can work together to win the Tournament of Power for their universe. Their combined strength would be a formidable force.
Definitely Goku. Their previous encounters in the Dragon Ball series make it a natural choice. Their power levels and different fighting styles would create great tension and action in the story.
One common theme is power and its control. Since Broly is known for her extreme power in the original series, in the fanfictions with a female Broly, a lot of stories focus on how she manages this power, especially in a world dominated by male Saiyans. Another theme is identity. As a female in a male - centric universe, she often has to find her place and prove herself.
Gohan and Robin would be an interesting pairing. Gohan, with his intelligence and powerful fighting skills, could bond with Robin over their shared smarts and desire to protect their respective worlds. They could exchange knowledge about combat strategies and detective work.
Ranma and Goku would be really interesting. Goku's pure love for fighting and his simple - minded yet kind nature would contrast with Ranma's more complex and often flustered personality. They could have some really fun training sessions together. Also, Bulma might be fascinated by Ranma's ability to change gender and try to figure out how it works scientifically.
