His character would likely face an internal struggle. On one hand, he has his values of friendship and protecting the village. On the other, he has this new relation to Lucifer which could bring out a more power - hungry side. For instance, he might be tempted to use Lucifer's powers for personal gain rather than for the good of all. He would have to constantly battle this internal conflict and decide who he really wants to be.
Naruto could also become more powerful but in a different way. His chakra might be tainted with a touch of the demonic, giving him new abilities that are both a blessing and a curse. He has to learn to control these new powers, which might make him seem more withdrawn as he trains in isolation to avoid hurting others accidentally.
Naruto would likely be very confused and hurt. He would grow up with a sense of abandonment that could make him more withdrawn at first. But this could also fuel his determination to prove himself, as he may feel he has to be strong without his parents. He might also be more eager to seek answers about his parents as he gets older.
His character development could also involve him becoming more of a strategic thinker. Guns require a different approach to combat than ninja tools. He'd have to think about ammunition, range, and reload times. This new aspect of fighting could force him to study more about his enemies' weaknesses and develop more elaborate battle plans. As a result, he could grow into a more well - rounded leader and fighter. He may also face challenges from his peers who don't approve of his new weapon choice, which would further shape his character as he defends his decisions.
Naruto's character in such a fanfic would be deeply affected. As a baby, being neglected means not having the love and care that shapes a person's view of the world. He would likely grow up with a sense of abandonment and unworthiness. This could manifest in his relationships. For example, he might have a hard time believing that his friends truly care about him. He may also be more prone to bouts of sadness or anger when he feels rejected, because his early experiences of neglect would make those feelings of rejection even more painful. He would constantly be seeking the love and acceptance that he didn't get as a baby, which could drive his actions and decisions in the fanfic.
In the 'naruto finds a gun' fanfic, Naruto may initially be excited by the novelty of the gun. But as he discovers its power, he could become more serious. His usual carefree and impulsive nature might be tempered. He would have to think twice before using it, as it has the potential to cause great harm. This could lead to a transformation in his character, making him more responsible and less reckless in combat situations.
He could become more somber. 'Bury a Friend' has a rather dark and moody feel to it. Naruto, who is usually so upbeat, might take on a more serious and pensive demeanor. This could change how his friends and villagers perceive him, and also how he approaches future challenges.
Naruto's confidence would likely be boosted. Having black angel wings gives him a unique power and appearance. He might become more self - assured in battles, knowing he has this special ability. However, he could also face some envy from his peers, which might make him feel a bit isolated at times.
If the doujutsu is very powerful, Naruto might become more confident, but also more cautious as he realizes the new responsibilities that come with such power. He would need to learn how to control it properly so as not to harm his friends or allies accidentally.
His core Naruto - like personality of being determined and never - giving - up would still be there. But he might become more refined and elegant like the elves. He would probably have more patience due to the elven influence. His boisterousness might be toned down a bit, but he would still be the energetic Naruto at heart, just with a more elven - like exterior in terms of behavior.
In this fanfiction, Naruto's character would experience significant growth. He'd be forced to confront the idea of family in a whole new light. His concept of good and evil would be challenged. Naruto, who has always been about protecting his friends and the village, now has to think about a much larger scale. He might start to question his own identity and purpose. His development would also involve learning about Darkseid's powers and trying to use them for good. He could become more of an outcast as some in the ninja world fear his connection, but this would only strengthen his resolve to prove himself. His journey would be filled with internal struggles and external battles, all of which would shape him into a more mature and complex character.
