How does Naruto obtain the Dragon Blade in fanfiction?

Perhaps it's passed down to him by a mysterious figure. This figure could recognize Naruto's potential and believe he's the right one to wield the dragon blade. The figure might be an old ninja who has been protecting the blade for years and now sees Naruto as the savior of the ninja world who needs this extra power.

He might obtain it through a special encounter. For instance, he could stumble upon an ancient dragon's lair where the chakra is stored and it bonds with him.

In some fanfictions, Naruto might obtain the dragon sword through a special quest. Maybe he stumbles upon an ancient temple during one of his missions where the sword is hidden as a powerful artifact, guarded by some kind of magic or traps. He overcomes these obstacles using his ninja skills and determination, and thus gets the dragon sword.

In a fanfiction, Naruto might be led to the ethereal blade by a series of visions. These visions could be sent by a spirit associated with the blade. He follows the clues in the visions, which lead him to a sacred place where the blade is hidden. There, he has to overcome some sort of guardian or obstacle to get the blade.

Perhaps he stumbles upon it during one of his adventures outside of the village. It could be in an ancient ruin or something.

He could obtain it through a powerful curse. For instance, a long - forgotten enemy places a curse on Naruto that not only gives him the blue Rinnegan but also sets him on a path to either destroy the world or save it depending on how he uses the power.

In some fanfictions, Naruto might obtain the Zero Tails through a mysterious encounter. For example, he could stumble upon an ancient artifact that houses the Zero Tails' power and it somehow bonds with him.

He could obtain it through a unique chakra infusion. Maybe during a battle with a powerful enemy who has some connection to an ancient chakra source, Naruto is accidentally exposed to a golden - hued chakra that fuses with his own and transforms his eyes into the Golden Rinnegan.

It could be that in the fanfiction, Naruto is exposed to a special type of chakra or energy source. This energy source could be related to an ancient artifact or a long - lost power. As Naruto has always been at the center of extraordinary events, his encounter with this special chakra could be the catalyst for him to obtain the True Rinnegan. It might also be that his previous battles and experiences have slowly been building up to this moment, and this final push of some external or internal factor causes the True Rinnegan to emerge.

Perhaps Naruto inherits the Rainbow Chakra. It could be a long - lost power that was once held by an ancestor. Through a series of events, like uncovering a hidden family heirloom or a secret scroll, he discovers his connection to this special chakra and learns how to unlock and use it. This would add a whole new layer to his character, as he now has a responsibility to uphold the legacy of this powerful chakra.
