Chōshinsei Rasengan

Derived from Jiraiya's Fire Release: Rasenbakuha, the Chōshinsei Rasengan is an S-rank jutsu created by Naruto Uzumaki, the result of fusing senjutsu training with his Rasenshuriken and Jiraiya's Rasenbakuha.

Naruto first creates a spiraling shuriken of wind chakra, a perfect Rasengan sphere at the center as chakra streams from it to form the shuriken, before adding fire chakra into the Rasengan. The result fuses Naruto's fire chakra into the Rasenshuriken, creating a large blazing vortex of fire, a white-hot Rasenshuriken serving as the core, before Naruto throws the vortex forward. The result is a large firestorm and blazing white-hot tornado, capable of levelling a battlefield in mere seconds due to the large amounts of fire chakra released with the attack, as well as a fierce hot wind of burning potential.

Initially, Naruto could only use this technique in his Sage Mode and, even then, it drained him of huge amounts of chakra. After training with B, however, Naruto became capable of using the technique, alongside more of his jutsu, in his Kyuubi Chakra Mode.
