How is Naruto's Perfect Susanoo different from the normal Susanoo in fanfiction?

Yes, in some fanfictions, Naruto is often given a perfect Susanoo. Writers like to experiment with different power combinations and abilities for characters, and giving Naruto the power of a perfect Susanoo is a creative way to make the story more interesting.

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.

It could be huge and have unique markings. Maybe it would be colored in Naruto's signature orange to match his overall aesthetic.

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, Naruto's Perfect Susanoo often has enhanced strength. It can be depicted as having more powerful attacks, like its sword strikes being able to cut through almost anything. Also, it might have unique abilities such as the ability to absorb chakra attacks from opponents and then redirect them with even greater force.

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.

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.

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.

She could try to appeal to Sasuke's emotions. If she can remind him of their past, of the times they fought together and cared for each other, it might make him release her. Sakura could talk about their shared experiences and how they are on the same side deep down, hoping to break through whatever is making Sasuke hold her captive.

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.
