Needle Jizō

This is a technique where the user encases themselves in a countless number of sharp needles, but in truth, the spikes are the user's hair. Chakra grants the strands of hair the hardness and shape of needles, endowed with a capacity to injure and kill on par with that of metallic weapons. In addition, if activated in response to an opponent's attack, it can also be used as a counter. The hair is made hard enough that it can withstand blows from certain types of weapons such as arrows.

When Chōji Akimichi used his Spiked Human Bullet Tank in Part II, he used a similar (if not same) technique as the Needle Jizō to form the spikes.
