It would change his abilities a great deal. The different bloodlines would give him a wider range of skills. Say he got the Nara's bloodline, he could use their shadow - manipulation techniques. This would add a whole new dimension to his fighting style. He could use the shadow techniques to immobilize opponents while he prepares his other attacks. Also, with bloodlines from various clans, his chakra control and capacity might increase, enabling him to perform more powerful and complex jutsus without getting exhausted quickly.
A possible storyline is that Naruto becomes a sort of unifying figure among the clans. With his multiple bloodlines, he could bridge the gaps between different clans that have had historical rivalries. For example, the Uchiha and the Senju. He might also discover a hidden prophecy related to his bloodline combination that makes him the key to saving the ninja world from a new, greater threat. Or, he could accidentally unlock a super - powerful technique that is only possible with his unique blend of bloodlines and has to figure out how to control it before it destroys him.
Well, having Shisui's eyes would likely give Naruto enhanced genjutsu abilities. Shisui's eyes are known for their powerful genjutsu. Naruto could use this to deceive his opponents more effectively in battle. He might be able to cast illusions that are much more difficult to break, and it could also potentially give him an edge in stealth operations as he could use the genjutsu to misdirect enemies.
If Naruto has the Raijin Sword in the fanfiction, his combat abilities would be revolutionized. The sword itself is a powerful weapon. Naruto could use it to cut through tough defenses that his normal attacks might not be able to penetrate. For example, some enemies might have barriers made of earth or water - based chakra. With the Raijin Sword, Naruto could slash through them with ease. Moreover, the sword could potentially be combined with his Sage Mode or his Jinchuriki powers. He could infuse the sword with his own chakra, such as the Nine - Tails' chakra, to create even more devastating attacks. This would make him a much more formidable opponent in battles.
Well, if Naruto has multiple kekkei genkai in fanfiction, his abilities could be enhanced in various ways. For example, if he has the Sharingan, he might be able to predict his opponents' moves more accurately like Sasuke. And if he has the Byakugan, his field of vision and perception would be greatly improved. This would make him an even more formidable opponent on the battlefield, as he could combine the powers of different kekkei genkai to create unique and powerful jutsu.
Well, if Naruto has Senju and Uchiha blood in fanfiction, his chakra reserves could be even more massive. Senju are known for their large chakra, and Uchiha have unique and powerful Sharingan - related abilities. So Naruto might be able to use both Wood Style more effectively like the Senju, and also access some form of Sharingan - like power. He could have enhanced perception and the ability to copy jutsu even better than before, and his combat skills would likely be a combination of the two clans' specialties.
First of all, having Madara's eyes would likely give Naruto access to some of the unique abilities associated with the Uchiha bloodline. For instance, he could potentially unlock the Mangekyou Sharingan's special techniques. This could change his combat style significantly. He might be able to use Amaterasu, the black flames, which would add a whole new dimension to his offensive capabilities. Also, the Sharingan could help him better understand and counter genjutsu, which is something that he wasn't as proficient in before. This would make him a more well - rounded shinobi in the fanfiction world.
Well, having the bird summoning contract could enhance Naruto's mobility a great deal. Birds can fly, so he could use them to quickly get to different locations, much like how he used to rely on his own speed. Also, the birds could potentially be used in combat, like swooping down to attack enemies or distract them while Naruto makes his move.
Well, if Naruto gets Shisui's Sharingan in the fanfiction, it could greatly enhance his perception skills. He'd be able to see chakra flow more clearly, which would help him in combat. He might also be able to use some of the Sharingan - specific jutsus like the Genjutsu techniques related to it. This would make him even more formidable against opponents, especially those who rely on stealth or illusions.
Well, Naruto already has his own powerful abilities like the Nine - Tails chakra. But with Shisui's eyes, he'd likely gain the power of the Sharingan. He could probably use the Sharingan's basic abilities such as seeing the flow of chakra and predicting movements better. Maybe he could also use Shisui's special jutsu, like Kotoamatsukami, which could be a game - changer in battles and in influencing others without them even realizing it.
Well, if Naruto gets the Sharingan in fanfiction, his combat abilities would be enhanced significantly. The Sharingan allows for things like predicting opponents' moves. Naruto could use it in combination with his already strong Rasengan attacks. He might be able to better analyze the flow of chakra in his enemies, making his taijutsu more effective too.
