- Users: Obvious
- Debut: Chapter 295, Shippuden Episode 42
While in his four-tailed form, Naruto disperses a massive amount of his chakra and blood into the air which take the form of many bubbles surrounding him. They come together to form a larger bubble that compresses to a smaller ball about the size of a peach pit that Naruto swallows, which explodes within him. He 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 Rashōmon gates without losing any of its momentum, and injuring Orochimaru in the process. Orochimaru has noted that if he were attacked by the ball or its feedback, he would surely be killed.
