If Naruto becomes a ghoul in a fanfic, he could potentially use his new powers in unique ways. His ninja skills combined with ghoul abilities like kagune would make him a very formidable fighter. Maybe he'd try to find a way to survive without harming innocent people, like finding alternative food sources or using his powers only against bad guys.
He could start by learning to control his new powers. Naruto is used to training hard, so he'd likely focus on mastering his kagune and other ghoul - related abilities. This would help him not accidentally harm anyone.
Another option is to ask in Naruto - related social media groups. Facebook groups, Reddit communities (such as r/Naruto), or Discord servers dedicated to Naruto might have members who are into 'ghoul naruto fanfic'. They could either recommend some they've read or might even be the authors themselves and share their own works with you.
One good 'ghoul naruto fanfic' could be one where Naruto gains ghoul - like powers and has to struggle with the new instincts while still trying to protect the village. For example, he might have a hard time controlling his newfound hunger for chakra, which is similar to how ghouls crave human flesh in the Tokyo Ghoul series.
The most interesting feature is the power combination. Godlike powers mixed with ghoul - like abilities like super strength and fast healing make for exciting battles. For example, in some fics, the character can use their godlike energy to enhance their ghoul powers even further.
Survival is also a big theme. Just like in the original Tokyo Ghoul series, where ghouls have to struggle to survive in a world that fears and hunts them, when combined with Naruto's world, characters from both sides often find themselves in situations where they have to fight for their lives. This can be against new threats created by the combination of the two universes or against the original enemies from each series.
One common theme could be the struggle for identity. Naruto, as a Ghoul, would have to figure out who he is now. Another theme might be acceptance, as he tries to get his friends to accept him despite his new nature.
Most Naruto fanfics tend to focus on his adventures, his relationships in a positive way, like his bond with Sasuke or his training with Kakashi. The idea of Naruto becoming a pervert is quite out of the ordinary for the Naruto - themed fanfic world. It's not something that is typically explored in mainstream Naruto fan creations.
It could be Naruto himself. He has a strong sense of justice and is always ready to face new challenges. His ability to adapt and learn quickly would make him a great protagonist in a world filled with ghouls.
One interesting concept could be the combination of the unique powers. For example, Naruto's ninjutsu combined with the kagune abilities from Tokyo Ghoul. It might create some really cool fight scenes and new power dynamics.
