The popularity of a 'naruto is a super saiyan fanfic' would depend on various factors. If the writer is able to write a good story that stays true to the characters' personalities while also exploring the new power - up concept well, it could be extremely popular. Social media would play a big role in spreading the word. If fanart and discussions start popping up, it could reach a wide audience. However, some purist fans might be against the idea at first, but if the fanfic is well - written, it could still win them over.
It could be about a character in the Naruto universe who somehow gains the power of Super Saiyan Rose. Maybe Naruto himself discovers a new form that is a fusion of his own chakra power and the Saiyan transformation. This new form could give him enhanced strength, speed, and the ability to fight stronger opponents.
A possible storyline could involve Naruto discovering a new form of power that combines his chakra with Saiyan energy, leading to his Super Saiyan - like transformation. He might then face a new and extremely powerful enemy that only his new form can defeat. Along the way, his friends would be both amazed and a little worried about this new side of Naruto.
Well, it could be a really wild and interesting concept. Imagine Naruto with the power of Super Saiyan Blue. He would be incredibly strong, his speed would be off the charts. His rasengan might even take on a blue glow and have the explosive power of a Saiyan attack. Maybe he could also fly around the Hidden Leaf Village like a Saiyan, which would surely shock all his friends and foes alike.
Well, an interesting plot could involve a fusion of the energy systems in both Naruto and Dragon Ball universes. Naruto, as Super Saiyan Blue Naruto, could be tasked with saving both universes from a threat that is causing the boundaries between the two to collapse. He would have to use his newfound powers, which combine chakra and ki, to stop the chaos and restore balance.
A possible plot is that an ancient scroll is discovered in the Hidden Leaf Village. When Naruto reads it, it unlocks a latent power within him that is related to the Super Saiyan 4 transformation. He starts to have visions of a being with great power who looks like a Super Saiyan 4. As he delves deeper into understanding this new power, he has to train in isolation. His enemies, thinking he's weak during this training period, launch an attack on the village. But Naruto emerges in his Super Saiyan 4 form just in time to save everyone and defeat the villains. This form could also give him new abilities like flying without the use of his shadow clones and enhanced sensory perception.
It could also be due to a strange prophecy. In both the Naruto and Dragon Ball worlds, prophecies play a big role. There could be a prophecy that a hero from one world would gain the powers of the other to defeat a common enemy. Naruto, being the hero of his world, is chosen and through some spiritual or magical transformation, he becomes a Super Saiyan.
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 start by looking on fanfiction websites. Some of them might combine the power - up concepts from the Super Saiyan in Dragon Ball with Naruto's ninja world, creating really interesting storylines.
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.
Well, in this kind of fanfiction, it might happen through some sort of cross - dimensional magic. Maybe there's a rift between the Naruto universe and the Dragon Ball universe that allows Naruto to gain the power of a Super Saiyan God. It could also be the result of a powerful wish made by a god - like character who decides to give Naruto this new form for the sake of saving his own universe or something like that.
