Wind Release: Rasenshuriken

The Wind Release: Rasenshuriken is a variation of the Wind Release: Rasengan, similar to the Great Ball Rasengan being a variation of the standard Rasengan. By manipulating the wind chakra of the Wind Release: Rasengan, Naruto was able to create four large points, making the Rasengan appear as a giant shuriken, the Rasengan in the center remaining a perfect sphere. Despite the name, because the Rasengan is a hand held jutsu, the Rasenshuriken can not be thrown, instead Naruto has to figure out a way to get close enough to his opponent and hit them. If successful, the victim becomes trapped in a vortex of wind chakra blades that attack the body on a cellular level. The wind chakra severs the chakra and nerve channels in the body.

 * Users: Naruto Uzumaki

The main drawback of the Rasenshuriken is that it is a double-edged sword. While it can utterly defeat any opponent trapped in the vortex, it also damages the users body. When Naruto used the Rasenshuriken twice on Kakuzu, it resulted him with limited cellular damage and a few broken bones. The Fifth Hokage has hence decreed the Rasenshuriken as a Kinjutsu, forbidding it as it could cause Naruto unable to mould chakra at all and possibly causing paralysis if important bones or organs would be fractured.
