The world of Naruto is filled with incredibly awesome ninjutsu. From Kakashi's lightning-filled Chidori, to the dastardly perverted Sexy no Jutsu, there's no shortage of imaginative jutsu in the Shonen Jump anime series. On the contrary, with so many amazing jutsu, it's easy to neglect some of the less famous techniques, even if they're super powerful. This is especially true with characters who only make a brief appearance in the long-running series.
Many of the underrated jutsu from Naruto are just as amazing as the protagonists' signature moves, and some are arguably more creative and powerful. In a few cases, a jutsu will only be unleashed once, but its effects are still incredibly memorable.
Its pretty common to see anime villains use hypnosis powers, but the Kotoamatsukami amounts to more than swinging a pocket watch back and forth in a memorizing way. The Kotoamatsukami is a near-perfect manipulation ninjutsu that makes its victims believe that they are operating under their own free will, whereas in reality they're being controlled by the technique's user. It's a frightening ninjutsu because the victims have no idea that they're being manipulated, since Kotoamatsukami fills their heads with false memories.
Welcoming Approach: Thousand-Armed Murder
Never incite the wrath of a goddess. While the spirit known as the Thousand-Armed Kannon is usually calm and peaceful, she will come at you with 1000 spirit fists if she's provoked. The Welcoming Approach: Thousand-Armed Murder is considered to be the ultimate technique of the Fire Temple, and this spiritual ninjutsu delivers a godly smackdown to unsuspecting foes.
Water Prison Shark Dance Technique
The Water Prison Shark Dance Technique is a powerful ninjutsu that surrounds its user with a massive dome of water. If that's not enough, the dome can change shape, which insures the user's victims never escape. The ninjustsu proves extremely useful for water-based ninja, such as the shark-like Kisame Hoshigaki.
Body Pathway Derangement
It's surprising that a high-level ninjutsu like the Body Pathway Derangement has roots in medicinal concepts. By cutting off the electrical signals in a person's brain, Tsunade can channel her chakra into her enemy's head, which gives her full control of their body. It's like spiritual possession that's backed by science (albeit ninja science).
