Power of the Five Kage

is episode 204 of the Naruto: Shippūden anime.

Synopsis
At the decimated Valley of Clouds and Lightning, Killer B emerges the watery depths and tells the Eight-Tails his plan to learn enka from Kin, leader of the enka ninja, which is why he faked his capture. After Tobi escaped, Kakashi tells Yamato and Naruto to keep the supposed truth of Itachi secret in case of it being false. Back at the summit, Sasuke uses his Susanoo to destroy the pillars and collapse the ceiling, allowing him and Karin to look for Danzō. Gaara protects everyone else in the room, except for the Raikage, who demolishes the debris falling on him with his powerful punches. Danzō uses Sasuke's arrival at the meeting place as a chance to escape. Ao pursues him. Sasuke also tries to follow him, but is stopped by the Fifth Mizukage. She battles Sasuke and nearly kills him, but he is saved by Zetsu's technique. Ōnoki uses his Dust Release technique and seemingly kills Sasuke. He then turns onto a devastated Karin, telling her she is the next. As the other Kage arrive, Tobi reveals himself at the summit, with an unconscious Sasuke on his shoulder, and sends him away with Karin, and says that he wants to tell them about his Eye of the Moon Plan.
