A Dragon Ball Broly fanfic often focuses on the character Broly. It might explore his backstory further, like his origin as a Saiyan. Fanfics could also depict his relationship with other characters in new ways, for example, his interactions with Goku and Vegeta. Some fanfics may give him different power - up scenarios or put him in unique battle situations that were not shown in the original series.
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.
If Broly joined the Tournament of Power, it would be an absolute game - changer. His raw power is off the charts. He could easily take on multiple opponents at once. He might start by targeting the strongest foes, like Jiren. His uncontrollable rage could work in his favor, as opponents would be intimidated. However, his lack of teamwork skills could also be a drawback. But with his power, he could probably just brute - force his way through many battles.
A fanfiction might explore Good Broly's relationship with the other Saiyans on Earth. Maybe he starts training with the younger Saiyans like Gohan and Trunks. He could teach them about the raw power of the Saiyans from his own experiences. This would lead to some interesting training sessions and a new bond forming between Broly and the rest of the Z - fighters.
The 'Dragon Ball Super Broly Novel' is an interesting expansion of the Dragon Ball universe. It delves deeper into the character of Broly, his backstory, and his power. It also explores the relationships between the other main characters in the face of this new and extremely powerful adversary. The novel may include more detailed descriptions of the battles, which are always a highlight in the Dragon Ball series.
Power - up is a common theme. Writers often come up with new ways for Broly to increase his power, like some unique training methods or new forms. Another theme is redemption. Since Broly is often portrayed as a villain in the original, some fanfics try to redeem him and turn him into a hero or at least an anti - hero.
The main plot often revolves around Broly, a powerful Saiyan. It might include his backstory, his battles, and his relationship with other characters in the Dragon Ball universe.
