One way Naruto might absorb chakra in fanfiction is if he has some sort of curse mark that instead of being a hindrance, it gives him the power to absorb chakra. He could touch an enemy with the curse mark and drain their chakra. Also, in some fanfictions, Naruto might be able to absorb chakra due to a new training regime. He could train with a hermit who teaches him a special meditation technique that allows him to draw in chakra from all around him.
In some fanfictions, Naruto might absorb Chakra through a special jutsu. For instance, he could use a self - created jutsu that allows him to draw in Chakra from his surroundings or from other characters he's in contact with.
Well, in some fanfictions, Naruto might absorb chakra through special jutsus. For example, he could have a unique kekkei genkai that allows him to draw chakra from his surroundings like plants or even the air. This gives him an almost unlimited supply in some stories, making him extremely powerful.
Perhaps there is an ancient artifact or a powerful curse that causes Naruto to absorb all chakra. In the fanfiction world, it's common to introduce such unique elements. For example, he might find a magical scroll that, when opened, starts sucking in all the chakra in the vicinity and then channels it into Naruto. Or it could be a curse placed on him by an enemy, but instead of harming him, it gives him this strange power to absorb all chakra.
There are also fanfictions where Naruto absorbs the chakra of ancient sages. This chakra is filled with wisdom and power, allowing Naruto to gain new insights into ninjutsu and also boost his overall strength.
One interesting way is when Naruto absorbs chakra through his shadow clones. In some fanfictions, the clones can be used not just to gather information or attack, but also to absorb the chakra of the opponents they interact with. Then, they transfer this absorbed chakra back to Naruto, making him more powerful.
Well, it could change the plot in many ways. For example, he might be able to defeat stronger enemies more easily. If he can absorb chakra during battles, he can quickly replenish his own and keep fighting without getting tired as fast. This would make him a more formidable opponent and might change the power dynamics in the story. Maybe he could even absorb the chakra of some of the main villains, which would completely disrupt their plans and change the course of the overall plot.
In some Naruto fanfictions, Naruto might absorb DNA through special jutsu or abilities. For example, he could have a unique kekkei genkai that allows him to take in and assimilate the genetic material of others. This could potentially give him new powers or abilities related to the DNA he absorbs, like if he absorbs the DNA of a Sharingan user, he might gain some form of Sharingan - like abilities.
In some Naruto fanfictions, Naruto might absorb animals through special jutsus or abilities. For example, he could have a unique kekkei genkai that allows him to take in the essence or chakra of animals. It could also be related to some sort of pact or bond he forms with the animals, which then enables him to absorb their powers.
In some fanfictions, it could be through a special jutsu. Maybe Naruto discovers a long - forgotten jutsu that allows him to merge with his dark counterpart. This jutsu might require a great deal of chakra control and concentration.
In some fanfictions, Naruto might absorb Momoshiki through a unique kekkei genkai. For example, if the author creates a new form of chakra manipulation that allows Naruto to assimilate Momoshiki's power during their battle. This could be a result of Naruto's Uzumaki bloodline having some hidden potential that gets unlocked in the heat of the fight.
