Chibaku Tensei (episode)

is episode 167 of the Naruto: Shippuden anime.

Synopsis
After Hinata is taken down by Pain's Deva Path, Naruto, bound and chained, becomes enraged. His automatic response to the failure of Hinata's actions to save him is the release of the Nine Tails. He morphs into his Four Tailed Kyuubi state and attacks Pain. He progresses in his transformation and bombards Pain in a flurry of enhanced Kyuubi attacks. Pain evades Naruto momentarily and from Nagato, he gains the strength to release a Sage type technique, Chibaku Tensei or Planetary Devastation. The release is initially manifested in the form of a small orb. Activation is shown when the orb attracts bedrock from beneath the earth. In his Six Tailed Kyuubi Form, Naruto attempts to stop Pain but the latter negates Naruto's attacks by encasing him in a earthly ball similar to the appearance of the Chibaku Tensei. Naruto is ultimately caught in the main technique where he makes furthur advancements to become the nine tails out of anger. On a mission elsewhere, Yamato senses Naruto has broken the seal and aborts his mission on Kabuto to help Naruto in anyway he can. At this time, Naruto is within his sub-conscience reflecting on conflicting feelings of pain and anguish, he succumbs to the Nine Tails' will but as he was about to break the sealing on the Nine Tails containment, The Fourth Hokage, Minato Namikaze, appears to stop him.
