There could be an original character created specifically for this fanfiction. This character might have a special connection to the 'creation of all things' concept, either as a guide to Naruto or as an antagonist who wants to steal this power for their own dark motives.
It could be Naruto himself still. Since it's related to Naruto, he might be the main focus as he tries to master or understand this new 'creation of all things' power.
Naruto is likely to be one of the main characters as it's related to the Naruto universe. Since it's about the creation of all things, he might be the one exploring or using this power.
In Naruto fanfiction, new characters can be introduced through a mystery or a prophecy. For example, there could be a prophecy about a powerful ninja who will come to change the fate of the ninja world. This then leads to the introduction of a new character who is believed to be that person from the prophecy. Another way is through a political situation. A new character could be introduced as a diplomat or an envoy from another village, bringing new political dynamics and storylines into the fanfiction.
Obviously Naruto would be one of the main characters since it's about him as the god of creation. Sasuke could also be a main character. He might be Naruto's ally or rival in this new story, depending on how the fanfiction is written.
Well, in Naruto fanfiction, creating new jutsus is a creative process. Some ninjas could create jutsus based on their emotions. For instance, a ninja who has experienced great loss might create a jutsu that is related to grief, like a jutsu that summons dark energy. Additionally, ninjas can also create jutsus by collaborating with others. Two ninjas with different elemental affinities could work together to create a combined - element jutsu. And sometimes, it's just pure inspiration from a dream or a vision that a ninja has, which then leads to the development of a new and unique jutsu.
One interesting idea could be new jutsu creation. In fanfiction, authors might come up with unique jutsu related to the concept of creation of all things. For example, a jutsu that can create entire landscapes or new types of ninja tools out of thin air.
One interesting part is the exploration of Naruto's character growth. With the creation of all things power, he has to learn responsibility. He can't just create things willy - nilly. He has to think about the consequences. Also, the fanfiction often explores how this power affects the existing power structures in the Naruto world. Will he disrupt the balance between the villages? Or will he use it to create a new, more equal balance? There are so many storylines that can come from this.
Since I don't know the exact 'all good things story', I can't say for sure who the main characters are.
It's likely that there is a strong - willed character, maybe a woman, who is trying to overcome the dangerous situations in the story. There could also be a sidekick or a friend character who helps the main character along the way. And perhaps there is an antagonist, someone causing the dangerous things to happen.
Since I don't know the exact 'all good things novel', I can't say for sure. But it could be characters like a kind-hearted hero, a benevolent old sage, or a group of friendly neighbors.
Maybe there's an older character who serves as a mentor. This character could have a lot of wisdom and guide the younger characters in the novel towards recognizing and appreciating the good things around them. There might also be a group of friends who each have different perspectives on what the good things are, and through their interactions, the story unfolds.
