The villains in Naruto Jutsu Master fanfiction can also be extremely powerful. They might have a dark jutsu that can drain the life force of others or a jutsu that can corrupt the minds of those around them. Their power often serves as a major obstacle for the heroes in the story, forcing them to grow and develop new jutsus to counter.
In many Naruto fanfictions, Sasuke is often depicted as a very powerful fire jutsu user. His Sharingan gives him an edge in precision and power when using fire techniques. He can combine his Sharingan's abilities with his natural Uchiha talent for fire jutsu, like the Great Fireball Jutsu, and make it even more destructive.
In fanfiction, the Lightning Dragon Jutsu can be extremely powerful. It can be depicted as a massive dragon made of pure lightning that can obliterate anything in its path. Another powerful one could be the Lightning God's Wrath, a jutsu that summons a bolt of lightning from the heavens with the power to level mountains.
There's also the 'Inferno Storm Jutsu' in some fanfictions. It creates a large - scale storm made entirely of fire. The fire in this storm has different intensities, with the center being the hottest and most destructive. It can cover a large area, making it a great offensive move against groups of enemies.
Naruto is also quite popular in these fanfictions. Fans love to write about him learning the Hiraishin no Jutsu and how it changes his fighting style. He's such a beloved character in the Naruto universe that seeing him master this powerful jutsu is always an exciting concept for readers.
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.
Definitely Naruto has to be at the center. But aside from the obvious ones like Sakura and Hinata, characters like Anko Mitarashi can also be part of the story. She has a unique personality that can add a lot of spice to the harem jutsu - related plot. Also, Kurenai Yuhi could be involved. Her calm and composed nature contrasts with the chaos that the Harem Jutsu can bring. And don't forget about Karin, who has her own history with Naruto and could be an interesting addition to the harem in fanfiction.
One possible powerful jutsu he could create is a time - freezing jutsu. This would allow Naruto to stop his opponents in their tracks, giving him the opportunity to either land a decisive blow or set up a more complex strategy. Since Naruto has always been about speed and surprise, this jutsu would add another dimension to his combat style.
Naruto himself is often involved. Since he's the main character, fanfiction writers like to explore how he would use or be affected by the mind transfer jutsu. Sasuke is another common one. His complex personality and powerful abilities make for interesting scenarios when combined with the mind transfer jutsu. Kakashi too, as he is a very intelligent and experienced ninja. Writers might explore how he would use the jutsu for strategic purposes.
In many Naruto fanfictions, Itachi is often depicted as an extremely powerful Mangekyou Sharingan user. His original abilities in the canon, like Amaterasu, are further enhanced in fan works. Sasuke is also a common focus. His Mangekyou Sharingan's powers can vary greatly from one fanfiction to another, sometimes with new and unique jutsu created by the authors. Another character could be Madara. Fanfiction writers love to explore the full potential of his Mangekyou Sharingan, often giving him abilities that were only hinted at in the original series.
Madara Uchiha was also very powerful. His mastery over the Sharingan, his grand plans and his combat skills made him a major threat throughout the series.
