Well, in these fanfictions, Naruto's harem can be all over the place. His godlike powers make him extremely desirable. Some fanfic authors might make his harem consist of characters who were once his rivals or those he has saved. The harem members usually play important roles in the story. They might be the ones who help Naruto control or understand his powers better. And they often get involved in his battles, either by providing support from the sidelines or directly fighting alongside him. There's also usually a lot of relationship drama within the harem as they compete for Naruto's attention in different ways.
They often start with a unique event. For example, Naruto could be exposed to a powerful chakra source that changes his physiology. This new source of chakra could be something ancient and otherworldly. Another way is through a bloodline awakening. Maybe Naruto discovers he has a hidden bloodline that gives him godlike powers. This could be related to a long - lost clan in the Naruto world.
In some fanfictions, Naruto's multiverse powers are portrayed as a way to bring together different versions of himself. Each version has its own set of skills and knowledge. By merging these aspects, he becomes an even more powerful and complex character, able to solve problems that were previously insurmountable.
One popular fanfiction could be 'Naruto: The Godly Ascension'. In this, Naruto might gain powers that are beyond normal ninja abilities, like the power to control time or manipulate reality at a large scale. Another could be 'Naruto: Divine Intervention' where he gets godlike powers to stop an otherworldly threat that the normal shinobi world couldn't handle. There are also ones where his godlike powers are related to his connection with ancient deities in the Naruto universe.
His ninjutsu might be enhanced by the magic in the Fairy Tail world. For example, his Shadow Clone Jutsu could have a magical aspect, like leaving behind a trail of magic energy. His Rasengan could also be powered up by the ambient magic, making it even more destructive.
It could be due to his unique connection with the nine - tailed fox. Since his parents are not there to guide him, he has to figure out how to coexist with the fox on his own. In this process, he might accidentally discover some hidden powers within himself. Maybe the nine - tailed fox, seeing Naruto's loneliness and determination, decides to share some of its power with him, which gradually makes Naruto godlike.
Often, it starts with Naruto obtaining his godlike abilities. This could be through a special training, a magical encounter, or some sort of inheritance. Then, as he becomes more powerful, female characters start to be drawn to him. The plot then develops as he tries to balance his relationships with them and also use his powers for good, like protecting the village.
In some Naruto fanfictions, Naruto's chaos powers might be shown as a wild and unpredictable energy source. It could make his jutsu more erratic but extremely powerful. For example, his Rasengan might become a chaotic, swirling mass of energy that can break through even the strongest defenses with ease.
His powers would likely be enhanced to a godlike level. For example, his Rasengan might be able to destroy entire landscapes with a single throw. His speed could be so great that he appears to teleport. His chakra reserves would be seemingly infinite, allowing him to spam powerful jutsus without getting tired.
Hinata is often a common character in Naruto's harem in such fanfictions. Given her deep love for Naruto in the original series, it's easy to include her. Sakura can also be part of it. Even though their relationship was more complex in the original, in fanfictions, she might be attracted to his new - found godlike powers. Another common one could be Ino. These three are popular choices as they are main female characters from the original Naruto series and can be easily integrated into a harem scenario around a powerful Naruto.
Well, often in fanfiction, Naruto's godlike chakra control is shown as a way for him to master new and unique abilities. He might be able to split his chakra into multiple minuscule strands to perform a kind of multi - targeted attack. It also enables him to better control the Nine - Tails' chakra, maybe even using it in ways that surprise both his allies and enemies. His chakra control is so refined that he can perform jutsu without the need for large - scale hand signs, making his attacks much faster.
