In some Naruto complete Susanoo fanfiction, there could be a plotline where the complete Susanoo has a sentient side. It might start communicating with the user, guiding them in battles or even in their personal growth. There could also be a story where different characters compete to unlock the complete Susanoo first, and the journey they take to achieve this involves facing their inner demons and learning new skills along the way.
Well, some fanfictions might have a plotline where the complete Susanoo can be combined with other powerful jutsus. Maybe the main character figures out a way to merge it with a nature - based jutsu, creating a whole new and overpowered attack. Or perhaps there's a story where the complete Susanoo is passed down through generations in a different way than in the original Naruto lore, leading to family feuds or alliances based on who can control it best.
One idea could be a crossover where Naruto somehow gains the ability to use Susanoo. Maybe through some strange chakra experiment. Another could be a fanfic that focuses on a character who is a huge Naruto and Susanoo fan and tries to recreate the power in their own way. And a third idea is a story set in an alternate universe where Susanoo is a common power among many ninja, and Naruto has to learn how to master it in a different way than in the original series.
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.
Well, in a 'naruto perfect susanoo fanfic', the character development related to those who can use the perfect Susanoo can be really engaging. Maybe it delves deeper into their emotions and how they handle such a powerful ability. Also, the fanfic could explore the battles where the perfect Susanoo is used in new and exciting ways, like combining it with other jutsu to create even more powerful attacks.
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.
Another plotline might be that Voldemort somehow finds out about Harry's connection to Susanoo and tries to use it to his advantage. Maybe he wants to steal Harry's powers or turn them against him. This would create a whole new level of conflict in the story. Harry would have to not only fight Voldemort's dark magic but also protect his new - found heritage.
There's a fanfiction where Naruto uses Susanoo after being experimented on by some rogue ninja. These ninja were trying to create a super - soldier by combining different bloodlines. Naruto, being the main character, overcomes the experiment and instead uses the newly acquired ability of Susanoo to take down the rogues and their entire operation. He uses it in a very strategic way, using its different forms to surprise his enemies and protect his allies at the same time.
Sasuke is often a very popular character in such fanfictions. Since he is one of the main users of the Susanoo in the original series, many fanfictions explore more of his adventures with the complete form. Naruto can also be popular as he might interact with Sasuke's complete Susanoo in unique ways.
There could be a fanfiction where a villain has mastered both the Mangekyou Sharingan and Susanoo in a way that no one has seen before. This forces the heroes to find new ways to combat this powerful foe, perhaps by delving into ancient jutsu that can counteract these abilities. It would be full of intense battles and strategic planning.
One interesting plotline could be the mystery behind the mask. Maybe it has some special power that only Naruto can unlock or it could be related to an ancient prophecy. Another could be a new villain who uses the mask to create chaos in the ninja world and Naruto has to stop him.
Perhaps Naruto discovers a new medical jutsu that combines his chakra control with traditional medical knowledge. This could revolutionize the medical field in the Naruto universe. He might use it to heal previously incurable diseases or injuries, and in the process, gain the respect of the medical community. This could also lead to some interesting interactions with other medical ninja, like Shizune or Tsunade.
