How would Naruto's character change if he had Hulk strength in fanfiction?

Naruto might become more cautious. Guns are very different from ninja tools, and one wrong move could be fatal. So he'd have to think twice before acting impulsively, which is a big change from his usual head - first approach.

He would become much more aggressive. Harry is usually a calm and strategic fighter, but as the Hulk, he would rely more on brute force and his first instinct would be to attack rather than think through a plan.

Naruto would become more introspective. The Mangekyou Sharingan often comes with a heavy burden and dark secrets. He'd have to deal with the new powers and the potential corruption they bring. For example, he might start to question his own motives more often.

If reborn as the Hulk, relationships would change drastically. With friends, they might be initially scared or in awe. Some friends could try to use the Hulk's power for their own gain. Family relationships would also be complex. If the character had a family before, they might worry about endangering them. Romantic relationships could be on the rocks. A partner might not be able to handle the new, often - angry and dangerous Hulk - form. But on the other hand, new relationships could form with other superheroes or people who are interested in the Hulk's power for good causes.

If Naruto had Sayian and Kriptonion DNA, his character would change significantly. The Sayian DNA would add a layer of cockiness to his personality. We see in the Dragon Ball series that Sayians can be a bit full of themselves when it comes to their power. Naruto might start to show off his new powers more. The Kriptonion DNA would give him a sense of justice on a larger scale. He would no longer just be focused on the ninja world's justice but would look at the broader picture of the universe. His relationships with his friends might also change as they have to adjust to this new, more powerful and different Naruto.

Naruto would become more powerful, and this might make him a bit more cautious. He's used to his regular ninja abilities, but the gura gura fruit's power is on a different level. He might be more hesitant in battles at first, not wanting to accidentally cause too much destruction with the fruit's earthquake - causing ability.

He might become more powerful. The Storm Release Bloodline could give him new offensive and defensive abilities, making him a more formidable opponent.

He would likely be more isolated at first. The Magu Magu Fruit powers are different from normal ninjutsu. His friends might not understand it fully, and he would need time to master it alone. This would make him more introspective, but as he gets better control, he would start to share his knowledge and use it for the good of the village. Also, his fighting style would change drastically. Instead of relying solely on his shadow clones and Rasengan, he would incorporate the heat - based attacks of the Magu Magu Fruit, making him a more versatile fighter.

If Naruto had 3 siblings, his loneliness as a child would have been much less. He would have had a support system from the start. His siblings could have helped him train, so he might have become stronger faster. For example, they could have sparred with him regularly. Also, in the story, when facing challenges like the Akatsuki, his siblings could have joined forces with him, making the battles more balanced and potentially having different outcomes.

His relationships with his friends might change a bit. His friends would be both amazed and maybe a little bit intimidated by his new powers. For example, Sasuke might see Naruto as an even greater rival now. And his relationship with his sensei, like Kakashi, would also be different as Kakashi would have to help Naruto understand and control these new alien powers.
