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.
DBS Broly is considered stronger. He has more advanced powers and abilities shown in the manga.
Generally, DBS Broly is considered stronger in fan manga. This is because he has more advanced techniques and powers. However, it's not a hard and fast rule. Different fan works might have different takes on their strength levels.
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 the manga, DBS Broly seems to have more refined and powerful abilities compared to DBZ Broly.
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.
In fan manga, the powers of DBS Broly and DBZ Broly can vary a lot. It depends on the creativity of the fan authors.
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.
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.
