In fanfiction, if Naruto knows all jutsu, it means he has an overwhelming advantage. He could defeat any opponent with ease. For example, against powerful foes like Madara, he wouldn't need to struggle as much. It also changes the power dynamics in the Naruto universe significantly.
Well, in a 'naruto therapy jutsu fanfic', it might be centered around how the ninja world lacks proper mental health support and so someone invents this therapy jutsu. For example, Sakura, being a medical ninja, could expand her skills to include a therapy jutsu that not only heals the body but also helps with things like PTSD that ninjas might suffer from due to the constant battles and traumas they face. It could also explore how different characters react to this new form of treatment.
In fanfiction, if Naruto becomes the master of all jutsu, he would be nearly invincible. He could use any technique to counter his enemies. For example, he could use powerful genjutsu like Tsukuyomi against tough opponents or advanced ninjutsu like Amaterasu. His combat strategy would become extremely diverse and unpredictable.
A 'naruto kawaii no jutsu fanfic' is likely a fan - made story related to Naruto's 'Kawaii no Jutsu'. It might focus on how this jutsu affects different characters in the Naruto universe.

The 'Naruto Harem Jutsu' in fanfiction is a cool idea that fans have come up with. It allows for a lot of creativity. Writers can explore different character dynamics when Naruto uses this jutsu. For example, they can show how Naruto deals with the sudden attention from multiple characters. But when it comes to the 'lemon' part, it's better to focus on the positive and family - friendly aspects of the Harem Jutsu fanfiction, like the development of relationships, the humor in the situations Naruto gets into, and how the other characters react to his jutsu.
There could be a jutsu that allows for instant teleportation across long distances. This jutsu might be a new discovery in the fanfiction world, perhaps created by a character who has been experimenting with space - time ninjutsu. They might use it to quickly get in and out of battles or reach far - off places in a blink.
He could achieve it through intense training. Maybe he finds a hidden scroll that contains knowledge of all jutsu and spends years mastering them one by one.

It changes the original story a great deal. In the original, Naruto has to strive to learn new jutsu. But in this fanfiction concept, he already has them all. This means he can handle threats much more quickly and efficiently. For instance, in battles that were difficult in the original, like against Pain, he could have ended it more swiftly.
