Piccolo, being more level - headed, might try to figure out a way to bring Goku back to his old self.

These are questions that fanfictions often explore. In addition, the relationships with his family and friends can change. Some fanfictions show how his new power level affects his relationship with Chi - Chi, for instance. He might be more distant as he is on a different power plane, or he could use his power to better protect his family in ways he couldn't before.
Power corruption is a common theme. Since Naruto has godlike powers in these fics, there's often a struggle with how much power he should use and whether it changes him for the worse.
Power struggles can also be a common theme. Dark Goku is often depicted as very powerful. Chi - Chi, on the other hand, has her own strength in terms of her determination and will.
