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.
Often, Orochimaru remains an antagonist even in these fanfictions. His thirst for power and immortality makes him a natural foe for Naruto, especially when Naruto has new super powers to protect. Another common one could be Madara Uchiha, as his grand plans for the world are likely to clash with Naruto's newfound abilities and his desire to protect peace.
In some fanfictions, Naruto might gain the ability to control energy like a laser beam which is an alien - like power. For example, he could shoot beams from his hands to defeat enemies.
If Naruto had avatar powers in fanfiction, the storyline would be turned on its head. His character development would take a new direction. He could use the avatar state not just for fighting, but also for diplomatic purposes. Imagine him using the power to show unity among the villages. His power level would be off the charts, which means the power balance in the Naruto universe would be disrupted. This would lead to a reshuffling of alliances. Some characters might side with Naruto because of his newfound strength, while others might try to undermine him out of fear.
If Naruto had ghoul powers in fanfiction, it would change the story drastically. For one, his combat style would be very different. Ghoul powers involve using kagune, which are like weapons made from the ghoul's body. Naruto's usual ninjutsu and shadow clone jutsu would be combined with these new powers. He might be able to use his chakra to enhance his kagune attacks. Also, his relationship with his friends could change. Some might be afraid of his new, more monstrous side. And his role in the ninja world would shift as he'd have to hide his ghoul nature from those who would hunt him if they knew.
If Naruto had Superman's powers in fanfiction, it would change everything. His village would be almost invincible. With Superman - like powers, Naruto could fly around and keep an eye on all the hidden villages, preventing any surprise attacks. His super strength could be used to rebuild the village in no time after any destruction. Also, his x - ray vision could be used for various things like finding hidden traps or enemies. The power dynamic in the ninja world would shift completely, and Naruto would become an even greater legend.
He could develop the ability to combine his chakra with Superman's powers. For example, he might be able to use his Rasengan while flying at super - speed. Or he could infuse his chakra into his heat vision to make it even more powerful.
The powers could be related to the elements. For example, if Naruto had a Zanpakuto bloodline, his Zanpakuto might be able to control fire in a more refined way than his normal jutsu, like creating intense blue - white flames that can cut through anything.
Well, Naruto could become a more stealthy fighter. With Rogue's powers, he might be able to absorb the chakra or abilities of his opponents, which would give him a huge advantage in battles. He could also use Rogue's power - related to stealth and misdirection - to infiltrate enemy bases more easily.
Maybe Naruto's god powers allow him to travel through different dimensions at will. He could visit the Otsutsuki home planet and learn about the true origin of chakra, and then bring that knowledge back to Konoha to revolutionize ninja training. He might also encounter other god - like beings in these dimensions and have to prove himself.
