His personality could be a mix of Saiyan pride and his original Naruto - ness. He may develop a sense of pride in his new power like a Saiyan would, but at the same time, he'd still be the goofy, determined Naruto. He might start to challenge stronger opponents more readily, thinking that his Super Saiyan God power can handle it, while still maintaining his loyalty and love for his comrades.
Naruto could become a bit more serious. Usually, he's quite carefree, but this new power might make him realize the great responsibility that comes with it. However, he wouldn't lose his core of kindness. He'd still be the Naruto who wants to protect his friends and the village, but just with a more solemn approach when it comes to using his new powers.
He might become more confident. With the power of a Super Saiyan God, Naruto would know he has a great strength within him. So, he'd be more self - assured in battles and decision - making.
Naruto might become more confident, bordering on cocky at times. The Super Saiyan 4 transformation comes with a lot of power, and with that power, he could start to believe he's invincible. But deep down, his core values of protecting his friends and the village would still remain. He might also become a bit more impatient, as the power coursing through him could make him eager to jump into battles quickly.
Naruto's personality could change in several ways in this fanfiction. Firstly, he might become more impatient. The Super Saiyan Rose power is extremely powerful, and he may want to use it right away to solve problems. Also, he could become more protective. Since he has this new and powerful form, he would feel a greater responsibility to protect his friends and the village. However, he would still retain his core values of friendship and loyalty. He might just be a bit more headstrong when it comes to defending those he cares about.
His confidence might increase significantly. Naruto has always been confident, but this new power could take it to a whole new level. He might become a bit more brash, thinking he can take on any opponent without hesitation.
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.
Well, if Naruto were a Super Saiyan in a fanfiction, the power dynamics would be completely different. Naruto's already strong ninja abilities would be amped up to a whole new level. His Rasengan could potentially have the destructive force of a Super Saiyan's ki blast. And his speed would be incredible, making him even more of a force to be reckoned with in battles against foes like Sasuke or the Akatsuki. Maybe he'd be able to fly too, which would change the way he approaches combat situations in the Naruto universe.
Naruto's character could develop a sense of pride that he didn't have before. This Super Saiyan 3 form is something extraordinary, and he might start to show it off a bit. But at the same time, he would also have to learn humility. If he becomes too arrogant, his friends might distance themselves from him. So he would be in a constant struggle between showing off his power and being the humble ninja he was raised to be. Also, his leadership skills might improve as he now has a power that others look up to, and he would need to lead by example when it comes to using this power responsibly.
Yes, there are quite a few. You can check out some fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'legendary super saiyan naruto' and you'll find a variety of stories, some might be about Naruto obtaining the power of a legendary super saiyan in some sort of crossover scenario.
One possible plot could be that Naruto discovers a hidden power within himself that is similar to the Super Saiyan God form. He then has to learn to control this new power while facing a powerful new enemy. Maybe this power also gives him new abilities like enhanced speed and strength, as well as the ability to sense ki like a Saiyan.
Their relationship could become more intense. Naruto's Saiyan traits might make him more protective of Hinata. For example, his increased sense of justice from the Saiyan side would make him even more determined to keep her safe from any harm.
He could become more cautious at first. Since it's a new world, he doesn't know what to expect, so he might hold back his usual boldness.
