Another possibility is Sasuke. Sasuke has always been a powerful and complex character. If he were to become the god of time and space in fanfiction, he might use this power to rewrite the history of the Uchiha clan. He could go back in time to prevent their downfall or change the way they were treated in the Leaf Village, which would have a huge impact on the entire Naruto story.
Perhaps a new character could be introduced as the god of time and space. This character could come from a different dimension or be a long - lost ninja with a special bloodline related to time and space manipulation. They could enter the Naruto universe and change everything we know about it, forging new alliances and creating new conflicts.
One possible antagonist could be Kronos again. Since Percy now has time - related powers, Kronos might see this as an opportunity to use Percy to his advantage. He could try to manipulate Percy into changing the past in a way that would free him from his eternal prison. Another could be a new, unknown deity who is jealous of Percy's newfound power over time and space and wants to take it for himself.
It could be an original character created specifically for this fanfiction. Somebody who has a mysterious past and the 'Right Hand of God' power.
Sasuke would also make a great main character. Given his affinity for lightning - based jutsus, he could be drawn to the Lightning God Slayer powers. He might see it as a way to become even more powerful and seek revenge on his enemies. His journey to master these powers could be filled with self - discovery and moral dilemmas.
Sasuke could be a great main character. Given his natural affinity for fire - based jutsu in the Naruto series, the addition of Fire God Slayer powers could make him even more formidable. He could use these new powers to seek revenge in a different way or to protect the village in a more powerful capacity.
Obviously Naruto would be one of the main characters since it's a 'naruto' fanfiction. There might also be other characters like Sasuke, who would likely be affected by Naruto's new time - related abilities. Kakashi could also be a main character, perhaps guiding Naruto on how to use his powers responsibly.
To develop Naruto in the Naruto God of Time and Space Fanfic, we can focus on his emotional growth. His time - space powers might isolate him from his friends at first because they don't understand what he's going through. He then has to learn to communicate his experiences and emotions. He could also develop new friendships with beings from different time - space dimensions. Through these interactions, he learns about different cultures and ways of life, which broadens his perspective. Additionally, his power development can be tied to his understanding of the time - space continuum. As he studies and masters it more, his overall character becomes more complex and mature.
In this kind of fanfiction, the Titans could also be antagonists. They might want to use Percy's power over time to their advantage. Maybe they think they can rewrite history in a way that would bring them back to power. Kronos, in particular, if he were somehow still a threat, could be a major adversary. He could try to manipulate Percy into using his time powers in a way that would benefit the Titans, like going back and changing events that led to their downfall.
It could be an evil ninja who has already made a pact with the Abyssal God and wants to use its power to take over the ninja world. He might see Naruto as a threat to his plans because Naruto has a natural connection to the god's power.
Maybe an ancient being that was sealed away long ago but has now been awakened due to Naruto's newfound power. This being has a natural hatred for those who can control lightning and sees Naruto as a threat to its plans of taking over the ninja world. It has the ability to manipulate shadows and uses them to counter Naruto's lightning attacks.
Perhaps an evil Pokemon scientist who has created a device that can control the minds of Pokemon. He discovers Naruto's arrival and sees him as a threat. So, he teams up with some of the most powerful and aggressive Pokemon to stop Naruto. He has no regard for the well - being of Pokemon or the balance of the world, only his own ambition to rule.
