While in his Four-Tailed Fox form, Naruto, Ryun or Sora conducts a massive amount of their Chakra and blood into the the form of a sphere, which they then consumes as it explodes within them. They then releases the explosion in the form of a massive wave of chakra from his mouth. The blast is so powerful, that it was capable of destroying three Rashomon gates. Orochimaru has noted that if he were attacked by the ball or its feedback, he would surely be killed. Seireitou can also use this technique in the form of a laser and a blast in his Bankai and Shukai form. His son Suzaku Hyuga can also use this technique in his Kyuubi State.
