If Naruto absorbs Broly in fanfiction, it could lead to some really interesting character developments. Naruto has always been about hard work and friendship, but with Broly's power, he might face new internal struggles. For example, he could struggle with the newfound brute force that might be at odds with his ninja way. Also, his friends might be a bit wary of him at first due to this sudden and extreme power change. But in the end, Naruto would probably find a way to use it for good, just like he always does.
When Naruto absorbs Broly in fanfiction, the story development would be quite complex. Naruto is from a world where ninjas and chakra exist, and Broly is from a world of Saiyans and ki. So, initially, Naruto would be very confused about the new power within him. He would try to understand how it works. His friends, like Sasuke and Sakura, would be both amazed and a bit worried. As the story progresses, Naruto might use this power to face an even greater threat that neither the ninja world nor his normal power could handle. And in the process, he would learn more about Broly's past and the nature of his power, which could further shape the story.

This doesn't mean Naruto would become a brute, but rather he could find a new balance between his kind - hearted nature and a more aggressive side when necessary. For example, in negotiations or battles, Naruto could be more intimidating. Also, Broly's loyalty to his own beliefs (even if they are sometimes extreme) could inspire Naruto to be more firm in his own ninja way.
