Rasengan

The Rasengan (螺旋丸 Spiraling Sphere) is the standard special move of Naruto and his final form, Kyūbi Naruto in Super Smash Flash 2. Naruto and Kyūbi Naruto summon a clone who builds up a ball of spinning chakra in his hand and then hurls it forward in a giant energy ball. The attack does decent damage as it is, but if it is fully charged, Naruto and/or Kyūbi Naruto will preform the Ōdama Rasengan (大玉螺旋丸 Great Ball Spiraling Sphere) which is a more powerful version of the attack. Kyūbi Naruto's version of the attack is much more powerful and has a red hue.
