Naruto would likely keep his shadow clone jutsu. This would be useful for various tasks such as scouting, spying, or even creating a diversion during a fight or a heist in the mafia world of the KHR crossover.
Well, Naruto's strong leadership skills from being a ninja could translate well into being a mafia boss in the KHR world. He might use his rasengan in new and creative ways to intimidate rivals. His loyalty to his comrades would also be a big part of his mafia leadership, much like how he values his friends in the Naruto series.
In a Naruto - mafia boss fanfiction, the story could involve Naruto leading a group of ninjas who have turned to a more underworld - style of living. He would have to deal with rival mafia groups. Naruto's rasengan could be his ultimate weapon against his enemies in this new setting. And his friends from the original series might also be part of his mafia crew. Maybe Sakura could be his medic, but also a tough fighter when needed. The story could explore how Naruto builds his mafia empire while still holding onto some of his original ideals. It could also show how he deals with betrayal within his own ranks, as loyalty is a big part of both the ninja world and the mafia world.
Well, in such a fanfiction, Naruto could have a whole new set of rules and a hierarchy within his 'ninja mafia'. He might be involved in things like smuggling goods or information between villages, but for the greater good. For example, he could be smuggling medicine to a village that is being oppressed by another. His character would be a blend of the original Naruto's determination and a new - found ruthlessness as a mafia boss. He would have to deal with rival mafia groups or ninja clans who oppose his methods. And his friends might be split between supporting him or trying to bring him back to the 'right' path.
Well, in a Naruto as a mafia boss fanfiction, he'd likely use his ninja skills in a new way. He could have his own group of loyal followers, like his ninja friends turned mafia members. Maybe he'd use shadow clones to be in multiple places at once for his 'business' operations.
I think Rock Lee and Gokudera would be a fun pairing. Rock Lee's extreme dedication to training and his unique fighting style would surely amaze Gokudera. Gokudera, in turn, could introduce Rock Lee to the power of the Dying Will Flame and how it can enhance combat abilities. Also, Kakashi and Reborn would be an interesting match. Kakashi's vast experience and intelligence combined with Reborn's shrewdness and unique training methods would make for some great interactions.
Inuyasha's demon blood could interact with Naruto's Nine - Tails chakra. Since both are sources of great power, they might be able to create a unique power - up. Inuyasha could use the Nine - Tails' chakra to boost his speed and strength even further, while Naruto could learn from Inuyasha how to better control his inner 'demon' side. Their combined power could be used to break through powerful barriers or defeat extremely strong foes.
Naruto's chakra and Kaguya's chakra are both very powerful but in different ways. Naruto's chakra is more about positive energy and his willpower, while Kaguya's is ancient and more raw. If they were to interact, Naruto's positive chakra might start to influence Kaguya's, perhaps making her more empathetic. For example, when they fight side by side, Naruto's chakra could boost Kaguya's attacks in a way that gives them a more moral or just - focused energy.
Their powers could combine in some cool ways. For example, Spiderman could use his web - slinging to help Naruto move around in a more aerial way, which would be a new experience for Naruto. Naruto could use his chakra to enhance Spiderman's strength or speed temporarily. Maybe Naruto could even infuse his chakra into Spiderman's web shooters, making the webs stronger or having special effects like being able to trap enemies in a chakra - based prison.
Their powers could combine in some cool ways. Naruto's chakra could enhance Wolverine's healing factor, making him even more resistant to damage. Wolverine's adamantium claws could be used in combination with Naruto's shadow clones. The clones could surround an enemy, and Wolverine could strike from different angles with his claws. Also, Naruto's ability to use different nature chakra like fire or wind could provide cover or additional offensive power while Wolverine gets in close for the kill.
