Flamed Rasengan

nlike the Fire Release: Great Flame Rasengan, the user does not ignite the Rasengan by spewing fire on it. Instead, Daisuke Kurama, the creator of the technique, mixed his own chakra element into the Rasengan, emphasizing the combination of the highest form of, and. This task proved to difficult for Kakashi Hatake, and even the creator of the Rasengan himself, Minato Namikaze, before his untimely death.

Daisuke mixed his own Fire Release with the Rasengan, while maintaining it's stability but increasing its power far beyond that of his ordinary Rasengan. After doing so, the Rasengan becomes much larger in size, and turns a black/reddish color. After using this technique on Nagato's Asura Path, it began to burn and melt even the chakra rods on it, nearly destroying it for good.

Trivia

 * At some point during his training, Naruto Uzumaki, came to Daisuke after hearing, from Kakashi that he had already mixed his own chakra element with the rasengan, technically making Daisuke the first to complete the technique.
