In some fanfictions, when Naruto absorbs the bijuu, he might gain overwhelming power. This could lead to him being able to easily defeat powerful enemies that were previously a threat. For example, he could single - handedly take on the Akatsuki without much difficulty.
In fanfiction, if Naruto absorbs all the bijuu, he would likely become an extremely powerful being. His chakra reserves would be off the charts, enabling him to perform incredibly powerful jutsu without much strain. He might also gain new abilities specific to each bijuu, like the ability to control different elements more proficiently or use their unique powers in combat.
Well, if Naruto absorbs all bijuu in this fanfiction, he'd probably be seen as a sort of super - being in the ninja world. His status would change drastically. He might face new challenges too, like dealing with the political unrest that his newfound power could cause. People would either fear him or try to use him for their own gains. And on a more personal level, he'd have to learn to control all that power, which could be a huge struggle, considering the different natures of the bijuu.
His character would likely develop a sense of greater responsibility. With all that power from the bijuu, he knows he has to use it for good. He might become more serious and less of the carefree Naruto we know at first. He'd also grow in terms of his self - confidence, knowing he has such incredible strength.
A plot twist could be that the bijuu themselves have a collective consciousness that Naruto doesn't expect when he absorbs them. This consciousness could start to influence Naruto's actions during his time travels. For instance, they might guide him towards certain events or people that they believe are important for their own reasons. Maybe they want to correct some past wrongs in the ninja world that were related to their existence. This would add an interesting layer to the story as Naruto has to deal with not only the power of the bijuu but also their will.
It could have a huge impact. With Naruto absorbing all the bijuu through time travel, the power balance among the ninja villages is completely disrupted. Some villages that relied on their own bijuu for protection or status might lose their advantage. This could lead to political unrest as they try to find new ways to assert themselves. Also, the overall perception of power in the ninja world would change. Naruto would become an extremely powerful and perhaps feared figure, which could either inspire others to follow him or try to bring him down.
In fanfiction, if Naruto is half - bijuu, it could mean he has enhanced physical abilities. For example, he might have greater strength and speed like a full - bijuu. His chakra reserves could also be much larger, allowing him to perform more powerful jutsu for longer periods.
It could be an ancient sage. In Naruto lore, there are sages who have had a great influence on the world. An ancient sage could be the one who created or fathered the bijuu. Maybe he had some great power and knowledge that allowed him to bring the bijuu into existence.
In many Naruto fanfictions, if Naruto has three bijuu, they could be the Nine - Tails (Kurama) which he already has in the original series, perhaps the Eight - Tails (Gyuki) as it has a connection with Naruto's world and Akatsuki's hunt for the bijuu. And another could be the Three - Tails (Isobu). However, it really depends on the specific plot and creative direction of the fanfiction.
It could be Shukaku. Since Shukaku was one of the first bijuu introduced in the series and has a sand - based power, it would be an interesting addition to Naruto's arsenal. Naruto's positive and energetic personality could also have an impact on Shukaku's usually grumpy and solitary nature.
