He would seek out mentors or ancient texts to learn how to master them. Along the way, he would make new allies and enemies within the demi - human world.

In this kind of fanfiction, one way it could develop is that Minato might be under some kind of dark influence. Maybe an enemy has a powerful genjutsu that makes Minato see Naruto as a threat to the village instead of his son. This would lead to actions that Naruto perceives as betrayal.

Another possibility is that a powerful enemy uses mind - control or deception to make those close to Naruto, like Sakura or Kakashi, turn against him. This would be a huge blow to Naruto as he values his relationships deeply.
