In fanfiction, with complete control of blood, Naruto could have a new form of healing. He could control the blood flow to injured areas more precisely, accelerating the healing process. Also, he might be able to detect the presence of enemies by sensing their blood, like a kind of blood - based radar. This would give him an edge in both offensive and defensive situations.
If Naruto has complete control of blood in fanfiction, it would likely change his relationships as well. His friends might be in awe of this new power, but also a bit wary. Enemies would definitely fear him more. He could use this power to protect his village in ways no one had ever imagined. For instance, he could create blood barriers or use the blood of defeated enemies as a warning to others. His newfound ability would also attract the attention of other powerful characters in the Naruto universe, leading to new alliances or rivalries.
It could be through some kind of ancient training method. Maybe he discovers a hidden scroll that details the art of blood control and spends months or even years mastering it.
In this fanfiction, Naruto might use the Omnitrix to gain various alien forms' powers. He could use those powers to fight stronger enemies in the Naruto universe, like the Akatsuki members. Maybe he would use the powers for stealth or super strength depending on the alien form.
In fanfiction, if Naruto gets sent to Blood Prison, he might face a lot of challenges. He could encounter powerful and dangerous inmates. Naruto would probably try to use his ninja skills and his strong will to survive. Maybe he'd also find some allies among the prisoners who recognize his strength and good heart.
Another feature is the character development centered around the blood control ability. Characters may struggle with the morality of using such a powerful and somewhat gory ability. They might have to overcome their own fears or the prejudice of others. In some fanfictions, characters with blood control abilities are ostracized at first because it's seen as something unnatural. So, it makes for really interesting internal and external conflicts.
If Naruto had Wolverine's power in fanfiction, it would change his fighting style completely. He'd no longer have to rely solely on his chakra. His adamantium - like claws could cut through the toughest defenses in the ninja world. Also, his endurance would be off the charts, allowing him to fight for days without getting tired, just like Wolverine.
Well, Naruto would become extremely powerful. He could use Sinbad's magic powers along with his own ninja skills. Maybe he could fly around the Hidden Leaf Village like Sinbad on his magic carpet and use his powers to protect the village in ways he couldn't before. It would be a really cool combination.
Naruto would likely become even more powerful. With the Sharingan, he could copy jutsus more easily, which would be a huge advantage in battles. He might also gain some of the Uchiha's unique abilities like seeing through illusions better.
In a fanfiction where Naruto secretly has the Rinnegan, he would become an even more formidable force. His combat abilities would skyrocket. He could potentially use the powers of the Rinnegan, like the Six Paths techniques, in addition to his existing Sage Mode and Nine - Tails chakra. This would make him a major threat to any enemy. He might be able to travel between dimensions more easily and have better control over life and death, just like Madara and Sasuke did with their Rinnegan.
In such a fanfiction, Naruto could easily defeat any enemy. He might be able to single - handedly end all the wars in the Naruto world. For example, he could take on the Akatsuki by himself and quickly dismantle their plans without breaking a sweat.
In such a fanfiction, Naruto would be extremely powerful. He could spam his powerful jutsus without getting tired. For example, he could keep using Rasengan continuously in battles, overwhelming his opponents. His Shadow Clone Jutsu would be even more fearsome as he wouldn't have to worry about chakra depletion when creating a large number of clones.
