Yes, it can be. In fanfiction, Goku being born with God Ki can completely change the power dynamics. It could mean he starts off with a much higher level of power than in the original story, leading to different battles and interactions. For example, his training might take a different path as he already has this innate God Ki. He could potentially face stronger opponents earlier and form different alliances.
Well, it could make him more confident. Since he has God Ki from birth, he might grow up knowing he's special. He may not have the same underdog - to - hero journey as in the original. Instead, he could be more of a natural leader from the start.
One effect is increased power. Naruto can become extremely strong and defeat powerful foes more easily. For example, he could take on enemies that were previously unbeatable in the original Naruto story.
Another theme is the impact on relationships. When Naruto has god ki, his friends might view him differently. Some might be in awe, while others could be a bit jealous. And his enemies will surely change their approach to him. Also, the concept of destiny often plays a role. Is Naruto meant to have this god ki for a greater purpose in the Naruto universe? The fic may explore this as well.
Yes, in some fanfictions Naruto can be depicted as having God Ki. Writers often like to give their own unique twists to characters, and giving Naruto God Ki is a way to enhance his power and make him even more extraordinary in the fan - created storylines.
One unique feature is the blend of two different power systems. Harry Potter has its own magic, like spells and potions, and God Ki brings in a whole new level of power. For example, in some fanfics, characters might use God Ki to enhance their spellcasting in ways not possible in the original series.
Perhaps in the fanfiction, Goku goes Super Saiyan early due to some special training or a unique emotional trigger. It could be that he witnesses the death of a different character, like Krillin, much earlier than in the original story. This extreme emotional distress causes him to break through his limits and transform. As a result, the Saiyan saga would take a different turn. Frieza might become aware of Goku's new power much sooner and plan different strategies to deal with him.
Vegeta could be a great rival. He might see Goku's new position as God of Destruction as another thing Goku has achieved that he hasn't. This could fuel their competitive nature even more.
Vegeta would also be an important character. His rivalry with Goku would intensify even more. Seeing Goku achieve the Super Saiyan form early would fuel his jealousy and his desire to become stronger. He might even try to find new ways to train or gain power to catch up with Goku.
