Ōdama Rasengan

The Ōdama Rasengan (大玉螺旋丸, "Giant Spiraling Sphere"), is the fully-charged variation of Naruto's standard special move in Super Smash Flash 2. This technique is a much more powerful version of Naruto's standard Rasengan and can trap opponents inside before blowing them away with incredible knockback. Like the regular Rasengan, Naruto uses a shadow clone to help form it. However, by adding increased amounts of chakra, he can increase the size and power of the standard Rasengan. It deals astounding damage to the area and the target, but it's useless with out getting close to the opponent. Kyūbi Naruto's version of this attack is called the Kyūbi Rasengan (九尾螺旋丸, "Demon Fox Spiraling Sphere") and is even more powerful than the Ōdama Rasengan.Naruto has shown that when he is under the influence of the Nine-Tailed Demon Fox's chakra, he can improve his use of the standard Rasengan and simultaneously make up for his shortcomings in performing the jutsu. The chakra cloak surrounding him while he is in his Kyubi form serves as the shell to stabilize the Rasengan's chakra, thus he does not need a clone to help as usual. Due to the influence exhibited by the Nine-Tails' chakra, this Rasengan changes from its blue color to a red color, made stronger than its standard version.[4] [5] Despite the fact that some video games give it its own name, Demon Fox Rasengan (妖狐螺旋丸, Yōko Rasengan; also "Vermilion Rasengan"), it is fundamentally the same jutsu. In SSf2, Kyubi Naruto uses the help of a shadow clone, eventhough he actually dosen't need the help of a clone.
