The Shadow Clone Jutsu used by Naruto is very memorable. He can create multiple clones of himself, which is useful in battles and for various tasks. The Sharingan abilities of the Uchiha clan are also quite remarkable. For example, the ability to copy other jutsu and predict movements. And of course, there's the Susanoo, a large, powerful avatar - like jutsu that some Uchiha members can use when they have awakened their Mangekyo Sharingan.
The Rasengan is one of the most iconic jutsu. It was created by Minato Namikaze and mastered by Naruto. It's a powerful ball of chakra in the palm. Another is the Chidori, which Sasuke uses. It's a high - speed, piercing attack made of lightning - style chakra.
Definitely the Rasengan. It's not only powerful but also represents Naruto's growth as he adds his own twists to it over time. Then there's the Amaterasu, a black - flame - based jutsu that is unique to the Uchiha clan. It's very difficult to extinguish. Also, the Summoning Jutsu is cool. Naruto can summon toads, and Sasuke can summon snakes, which play important roles in battles and story - telling.
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.
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.
In some fanfiction, there's a jutsu called 'Shadow Clone: Overdrive'. Naruto creates so many shadow clones that they form a huge tidal wave of clones. This is a really exciting jutsu as it overwhelms the opponent with sheer numbers and can be used for various strategies like surrounding the enemy, or using the clones as a shield while the real Naruto attacks from a hidden position.
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.
A 'Solar - Flare Rasengan'. Naruto could combine his wind - style chakra with some kind of solar - based energy he discovers. This jutsu would be like a super - charged Rasengan that emits a blinding light as well as powerful wind - based damage.
The most exciting part is seeing new powers. For example, when Naruto gets a new jutsu, it could be something that completely changes the way he fights. It's like getting a new superpower.
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.
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.
One creative use is turning the bubbles into mini - prisons. In some fanfictions, Naruto can trap enemies inside the bubbles, which are then made unbreakable. This is a really cool and unique way to use the jutsu.
One of the most memorable battles is the fight between Naruto and Sasuke at the Valley of the End. It's a very emotional and intense battle that showcases their complex relationship.
