In fanfiction, Naruto chakra rods can have various functions. They can be used as a tool for energy transfer. For example, some characters might use them to channel their chakra to other objects or people. They could also serve as a weapon, perhaps with the ability to paralyze opponents when inserted into their bodies, as they are often shown to disrupt chakra flow in the Naruto series.
Some fanfics might depict the chakra rods as a means of communication. Since they are made of chakra, they could potentially be used to send messages or signals between ninjas over long distances. This would be like a chakra - based telegraph system.
In fanfiction, the chakra rods can be more powerful. They might be able to carry different types of chakra, not just the normal chakra we see in the original series. For example, a fanfic could introduce a new form of elemental chakra that can be channeled through the rods.
They can be a major plot device. For instance, if a villain gets hold of a large number of chakra rods, they could use them to control other ninjas against their will, leading to a big conflict where the heroes have to find a way to break the control.
One interesting concept could be a character unlocking the hidden potential of the chakra gates in a unique way. For example, they might discover a new sequence of opening the gates that gives them powers beyond what was thought possible in the original Naruto lore.
One consequence could be that he becomes extremely powerful. His physical abilities like strength, speed, and endurance are enhanced. He can also use more powerful jutsus with the extra chakra boost from the Kyuubi.
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.
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.
The consequence might also be a shift in the balance of power in the Naruto universe. With all that chakra, Naruto could potentially change the political situation. He could end wars single - handedly or force the different ninja villages to re - evaluate their strategies. Moreover, his own physical and mental state might be affected. There could be a struggle within him to keep his identity intact while dealing with such an overwhelming power source.
He could share it with Hinata. Given their relationship, Naruto might transfer some of his chakra to Hinata to protect her during a dangerous situation. This would also strengthen their bond further in the fanfiction.
