If Naruto becomes a super soldier in fanfiction, he may change in terms of his personality too. With great power often comes a sense of responsibility or in some cases, overconfidence. He could start to view himself as an even greater protector of the Hidden Leaf Village, but also might struggle with the newfound power and how it sets him apart from his friends. Also, the story could explore how the other characters react to this 'super' Naruto, whether they are in awe, jealous or feel more secure with him around.
Well, he'd probably be an even more formidable wizard. He could use his super soldier strength and agility along with his magic. Maybe he could cast spells faster or endure more difficult magical tasks without getting tired so easily. He might also be able to combine his combat skills from being a super soldier with his dueling skills, making him a really tough opponent in any magical battle.
Well, he would probably be an amazing soldier. Given his skills from his demigod adventures, like his combat abilities and quick thinking. He could use his sword - Riptide - to great effect. Maybe he'd be part of a special unit in the fanfiction, using his powers to protect his comrades and take on dangerous missions.
He would probably become extremely powerful. The Super Soldier Serum is known for enhancing physical abilities. Naruto already has his chakra powers. With the serum, his strength, speed, and endurance would likely skyrocket. He might be able to take on much stronger opponents in the DxD universe with ease.
Well, if Naruto becomes the Kyuubi in the fanfiction, he would likely have an overwhelming amount of power. He might be able to defeat his enemies with ease. But he would also face the struggle of controlling such a powerful and wild force inside him. Maybe his friends would be both in awe and a bit scared of him at first.
If Naruto becomes super IQ in the fanfiction, he could potentially become a master of multiple fields. He could be an excellent diplomat, using his intelligence to negotiate treaties and alliances. He would also be a great inventor, creating new tools and weapons for the ninja world. His friends might be a bit in awe of his newfound intelligence at first, but they would soon realize that he's still the same Naruto at heart, just with a much sharper mind.
Well, if Naruto becomes a homunculus in fanfiction, he might gain some unique alchemical powers. He could have enhanced physical abilities like super strength and speed, similar to what homunculi typically possess in the original concept. His ninja skills would probably merge with these new powers in interesting ways.
Well, in such a fanfiction, Naruto would likely lose all his skills and knowledge as a ninja. He'd be completely dependent on others for care, like eating baby food and being diaper - changed. Maybe his friends would have to protect him from the enemies who might see this as an opportunity to get rid of him once and for all.
Well, if Naruto becomes the reaper in fanfiction, he would probably have a whole new set of powers. He could start reaping souls in the Naruto universe, which would be a huge change. Maybe he'd use his new reaper abilities to deal with the more dangerous enemies in a different way, like sending their souls to some sort of afterlife realm.
If Naruto becomes an Arrancar in a fanfiction, he would likely gain new and powerful abilities. Arrancars have unique Hollow powers, so Naruto might be able to use Cero or other Hollow - based attacks. His physical abilities could also be enhanced, and his appearance would change to something more like an Arrancar. He might struggle with the more evil tendencies that come with being an Arrancar at first, but being Naruto, he would probably find a way to use these new powers for good and protect his friends and the village in a different way.
Well, if Naruto becomes Mikoto, he would be a female in the body of Mikoto. He could bring his own values and experiences as Naruto. This could potentially change the relationship dynamics within the Uchiha clan. He may try to bridge the gap between the Uchiha and the rest of the village in a way that Mikoto might not have been able to do in the original story due to her own limitations and the circumstances of the time.
