Naruto's story would be completely transformed. He would no longer be just a ninja with chakra powers. The Blacklight virus would introduce a whole new element of biological chaos. His body would start to change, and he'd have to learn to control these changes. His journey would become one of not only protecting the village and his friends but also of self - discovery and survival. He might even have to travel to new places in search of a cure or knowledge about the virus, leaving Konoha behind for a while and facing new enemies and allies along the way.
If Naruto got the Blacklight virus in fanfiction, his story would take a very different turn. His usual sunny and positive attitude might be tested. He could start to doubt himself.

His relationships with his friends and foes would shift. Some enemies might see him as a new threat, while his friends would be worried and try to support him.
Harry might become more of an outcast. His friends may not understand what's happening to him with the virus. This could make him bitter at first, but as he learns to control the virus, he could become more self - reliant and determined. He would also have new powers from the virus, which could make him a bit cocky at times as he figures out how to use them.
His character would likely become more complex. He might initially feel a sense of isolation as he realizes he's different now with the virus. But he could also grow more determined to control the virus and use it for good. For instance, he may see it as a new kind of power he has to master, just like his chakra.
Sasuke would likely be very cautious at first. He would see the virus as a potential threat to his goals and might try to study it from a distance. Naruto, on the other hand, would probably be more impulsive. He might try to directly confront those affected by the virus, thinking he could talk them out of causing harm. Sakura would be more scientific about it. She would want to research the virus and find a medical cure.

And with his other friends like Shikamaru, they might be more cautious around him at first but then rely on his virus - enhanced abilities in battles.
Well, Naruto would likely face a whole new set of challenges. His ninja skills might be put to the test in a different way. He'd have to figure out how to deal with the virus's effects on his body, like maybe it would enhance his physical abilities in some strange ways, but also pose a threat to his chakra control.
