Well, it would be an extremely powerful combination. Naruto has his ninja skills and chakra, while Broly is a Saiyan with insane strength. Maybe they'd create new and unique fighting techniques. Their fused form could have Naruto's determination combined with Broly's raw power, making them a force to be reckoned with in the fanfiction universe.
The story could start with some sort of magical or scientific accident that causes the fusion. Then, they might have to deal with people being afraid of their new, extremely powerful form. Their friends would be confused at first but then try to help them control this new power.
If Broly participated in the Tournament of Power, he would be an absolute powerhouse. His raw strength and uncontrollable rage could either make him a wild card that disrupts the whole tournament or a key player for his team. He might start by randomly attacking opponents without much strategy, but as the fight goes on, his natural fighting instincts could kick in and he could become a real threat to the strongest fighters in the multiverse.
It could lead to a completely different character arc and story development. Maybe she'd have a softer side or face different challenges due to gender expectations in the Dragon Ball universe.
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.
Broly's sad tale is a complex one. He was a Saiyan with incredible potential, but his own people rejected him. The Saiyans were afraid of his power and banished him to a dangerous planet. Growing up in isolation, he developed a violent and angry nature. His only connection to his past was his hatred for Goku, which was kind of misdirected. This hatred drove him to constantly seek revenge, but really it was all because he was so alone and mistreated as a child. He was a victim of his own people's fear and jealousy.
Well, it could be about Broly's experiences in hell. Maybe it shows his struggles, his encounters with other hellish beings, or his journey to either find a way out or gain power within that infernal place.
It's mainly about the story of Broly in the form of a light novel. It might explore his character, his powers, and his place in the Dragon Ball universe in more detail through written narrative.
Since Broly is a character from the Dragon Ball franchise, if there is a 'Broly Love Story', it might involve him finding love among the various races in the Dragon Ball universe. Maybe he meets a female Saiyan or someone from another planet and they form a connection through shared experiences, like fighting together against a common enemy. But again, this is all speculation as it's not a common part of the official story.
