Another way is to have Naruto fuse his chakra with someone who has the ability to use Susanoo, like Sasuke. They could create a combined form that has the best of both their powers. The story could detail their journey of learning to work together and master this new form.
Perhaps in a post - apocalyptic fanfiction setting, Naruto discovers an ancient scroll that teaches him how to mimic Susanoo using his own Uzumaki chakra. He then uses this new - found knowledge to protect what remains of the ninja world from various threats. This would involve a lot of world - building in the fanfiction to explain the post - apocalyptic state and the significance of Naruto's new power.
Some fanfictions might play with the idea of alternate universes. In an alternate universe, the rules of ninjutsu are different. Naruto could be born with a combination of Uzumaki and Uchiha bloodlines, which would make it possible for him to use Susanoo. Or perhaps he is given this power by a powerful entity in the fanfiction for the purpose of fighting a greater evil that no one else can defeat.
Well, in many fanfictions, Naruto might first awaken Susanoo during a really intense battle. Maybe he's pushed to his limits while fighting a super - strong enemy, and his latent Uchiha blood (if that's part of the fanfic's premise) gets activated, leading to the awakening of Susanoo.
In fanfiction, the Perfect Susanoo is usually much larger and more powerful than the normal Susanoo. It might have additional limbs or weapons that the normal one doesn't have. For example, it could have extra arms to hold more weapons or perform multiple attacks simultaneously.
In some fanfictions, Naruto might use Susanoo through some sort of power - sharing or fusion. For example, if there is a plot device that allows him to access the power of the Uchiha, he could potentially use Susanoo. Maybe a powerful enemy forces him to find new ways to power up and he somehow taps into this ability.
The abilities might be different too. Since Naruto has his own set of skills like the Rasengan and Sage Mode, his Susanoo could incorporate those elements. For example, his Susanoo's hands could form giant Rasengan - like attacks, or it could have the ability to enter Sage Mode, which would be a huge departure from the regular Uchiha Susanoo's abilities.
Yes, he can. Fanfiction allows for a lot of creative liberties. Writers might imagine a scenario where Naruto somehow inherits or gains access to the Sharingan and then progresses to unlock Susanoo. For example, through some magical or chakra - related accident that fuses Uchiha genetics or power with Naruto's own. But it's important to note this is purely a fan - created concept and not part of the official Naruto lore.
Yes, it is. Fanfiction often bends the rules of the original story. Writers can come up with all kinds of creative explanations to give Naruto the ability to use Susanoo.
One idea could be a story where Naruto somehow gains the ability to use Susanoo. Maybe through some strange chakra experiment gone wrong or a gift from an ancient entity. He then has to learn how to control this new power while still maintaining his own ninja way.
They can be combined through a portal concept. A portal opens between the Naruto universe and the Transformers universe, bringing Naruto and Arcee together. Then they can work towards a common goal like saving both universes from a threat that spans across dimensions.
Well, in a Naruto - Game of Thrones fanfiction, you could have the Sharingan (from Naruto) be a rare and mysterious power in the Game of Thrones world. Maybe a character discovers they have this power and it's seen as a sign from the gods. And then, just like in Naruto, there are different levels of power associated with it. This could lead to new alliances being formed as houses try to either control or protect the person with the Sharingan.
