The strongest Forbidden Jutsu of the Uchiha clan is known as Izanagi. This Jutsu allows the user to turn illusion into reality and in doing so, change the events in real life. Most of the time that Izanagi was used, it allowed the user to survive death by rewriting it.
1 Baryon Mode
Recently used by Naruto Uzumaki, Baryon Mode is an extremely powerful jutsu that was available to Naruto Uzumaki and Kurama when they were together. This jutsu used their chakra as raw materials to give rise to incredibly potent energy, akin to nuclear fusion, that far exceeded anything seen in the story.
Forbidden Jutsu, also known as Kinjutsu, is a type of Ninjutsu that has been banned from being taught or used. The term originated after the warring states' end when newly formed hidden villages agreed to forbid certain techniques to reduce unnecessary bloodshed and keep the peace.
1 Kaguya Otsutsuki
She wields the Rinne-Sharingan, which is needed to cast the strongest Genjutsu in the entire series. With her Rinne-Sharingan, Kaguya can cast the Infinite Tsukuyomi over the entire world.
A very simple technique with an over-dramatic name, One Thousand Years of Death is little more than inserting one's index and middle fingers (similar to the Tiger hand seal) into the opponent's rectum, causing constipation, pain and/or embarrassment. It has no effect on unconscious targets.
One of the strongest known Kekkei Genkai in Naruto, the Rinnegan is the rarest of the Three Great Dojutsu. This eye holds tremendous significance in the Naruto world and it is believed that those who hold this eye would either bring great destruction or a great change in the world for the good.
Gaara's Sand Clone technique is one of the strongest due to its flexibility in any situation. Decoy Sand Clones can lure opponents in before overwhelming them with techniques like Sand Spear or Sand Burial.
Hiden Jutsu (meaning "Secret Techniques") are techniques pass down from generation to generation in certain regions or clans. The groups possessing these techniques are usually extremely secretive about them. They ensure that no one other than the members of the group learn them.
4) Rope escape. This escape Jutsu is taught to the students at the academy. This technique teaches the shinobis to escape from the ropes by either finding a way to untie them or dislocating their joints to free themselves from the binding. It is one of the simplest Jutsus in Naruto.
The Raijin Slice combines space-time jutsu with a sword or other bladed weapon. The user teleports to a marked target in an instant to deliver a devastating blow. Not even the Sharingan can keep track of a ninja using a Raijin technique. Because of that fact, Raijin jutsu are the fastest in the entire Naruto world.
Naruto Uzumaki
Evidently, Naruto managed to accomplish what his father couldn't, and eventually completed the Rasengan. The yellow-haired protagonist is arguably the most extensive user of the Rasengan in Naruto, having managed to create multiple forms of the technique.
1 Infinite Tsukuyomi Turns People Into White Zetsu
Every single person is trapped in its power, and when that happens, they slowly have their chakra drained from their bodies. At the same time, those affected by this jutsu are then converted into White Zetsu over a period of time.
Rasengan was the 2nd hardest jutsu cause it was difficult to manipulate the chakra the way it does. A normal ninja can also find it difficult to master.
1 The Reaper Death Seal Literally Kills The User
The jutsu forces the user to call upon an actual Shinigami, but its very existence is highly classified because of how powerful and dangerous it is. The Shinigami chants until a cursed seal appears on its arm, and it then drives the arm through the user's soul.
Although the Rasenshuriken can destroy the opponents at a cellular level with countless cuts, it also damages Naruto's chakra system. As such, this technique was forbidden by Tsunade Senju, the Fifth Hokage.
The shadow clone jutsu was developed by none other than the second Hokage, Tobirama Senju, and it creates a physically solid copy of the user (as opposed to illusory clones). The user's chakra is split evenly between the original and the clones that he or she creates.
1) Six Paths Sage Mode - used by Naruto
Rightfully known as the strongest Sage Mode, Naruto gained the Six Paths Sage Mode from the Sage of Six Paths. This happened when the two met in the Fourth Great Ninja War. With this power, Naruto became so powerful that even Madara had a hard time fighting against him.
3 Six Paths Sage Mode
The Six Paths Sage Mode has become Naruto's go-to transformation. He gained this power after meeting the Sage of Six Paths, Hagoromo Otsutsuki. When compared to all his other transformations, the Six Paths Sage Mode is extremely special.
Simply put, the Infinite Tsukuyomi is a powerful genjutsu than can be performed through the Rinne-Sharingan – a powerful Dojutsu. This genjutsu is reflected off of the moon and is then cast on the entire population, enslaving everyone in an eternal slumber.
The Immortality Jutsu Orochimaru developed involves not extending his own body's life but forcibly transferring his soul into other bodies and taking them over. The process involves him transforming into a giant white snake, his true form. Orochimaru's mind remains intact while he switches bodies somewhat regularly.
Future Sight (後御目, Nochiome) is a precognitive dōjutsu utilized by Chikara through the power of his Hakkeshō Byakugan. After receiving a variation of the Tenseigan from Hamura, Chikara still retained the ability to perform this technique.
