Well, his super powers might make him a target at first. People could be either jealous or scared of him. So he might have a hard time making friends. He'd also probably attract the wrong kind of attention from some villains who want to use his powers for their own evil plans.
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.
Some fanfictions have Naruto getting super powers as a result of a divine intervention. Maybe the gods or goddesses of the Naruto universe see his great potential and decide to give him additional powers to help him in his quest to bring peace. This can lead to all sorts of interesting plot developments, like him having to prove himself worthy of these powers to the divine beings or facing the envy of other ninjas who don't have such divine blessings.
One super power often seen in such fanfiction is elemental manipulation. A character could have the power to control all four elements - fire, water, earth, and air - with great precision. They might be able to create huge firestorms to fend off dark wizards or summon tsunamis within the Hogwarts lake. There are also super strength powers where a wizard or witch can lift extremely heavy objects, like the entire Hogwarts castle, which comes in handy during battles against powerful dark forces. And of course, there's the power of invisibility without the need for an invisibility cloak, which gives a character an edge in spying or sneaking around.
If Naruto was born in the Uchiha clan in fanfiction, he would surely have the Sharingan. This powerful eye technique would give him enhanced perception, allowing him to copy other ninja's moves more easily. He could also use Genjutsu more effectively. Along with that, he might still have some connection to the Nine - Tails, but it could be more subdued or combined with his Uchiha powers in a unique way. Maybe he could use the Nine - Tails' chakra to boost his Sharingan abilities, like increasing the power of his Amaterasu if he were to unlock it.
He might have powers like shape - shifting into a more demonic form. Maybe he could have the ability to breathe fire or some other elemental powers related to chaos or destruction. He could also have enhanced strength and speed that are far beyond what a normal ninja has, and his senses could be super - sharp to detect danger or prey.
His powers might adapt to the urban environment. His Shadow Clone Jutsu could be used for distraction during heists or when facing gangs. For instance, he could send clones into different alleys to confuse the criminals. His ability to sense chakra might be tweaked to sense danger or the presence of super - villains in Gotham. Maybe it would work like a sixth sense for him in this new setting.
One possible power could be instant teleportation within a certain range. Some sage - like abilities in Naruto involve quick movement between spaces. Naruto, as a born sage, could use this to surprise his enemies in battle. He could suddenly appear behind an opponent or quickly move to a strategic location, giving him an edge in combat.
Well, Naruto's transformation into a Super Saiyan would likely bring a whole new level of energy manipulation. The Super Saiyan form is known for its intense ki energy, and Naruto's chakra could blend with it in interesting ways. His stamina would probably increase, enabling him to fight for longer periods without getting tired. His ability to sense danger and opponents might also be heightened, similar to how Saiyans can sense ki. And his overall presence on the battlefield would be much more intimidating.
