Rasengan

The Rasengan 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 chakra in his hand and then hurls it forward in a giant energy ball. The projectile does massive damage as it is, but if it is fully charged, Naruto and/or Kyūbi Naruto will preform Ōdama Rasengan which is a mote powerful version of the attack; additionally, Ōdama Rasengan  creates clouds of dust behind it which sucks in enemies. Kyūbi Naruto's one is more powerful than the regular Rasengan and deals multiple hits if it isn't fully charged.
