Power of the Five Kage

is episode 204 of the Naruto: Shippūden anime.

Synopsis
At the ruined Valley of Clouds and Lightning, Killer B emerges the watery depths and tells the Eight-Tailed Giant Ox his plan to learn enka from Kin, leader of the enka ninja, which is why he faked his capture. After Madara 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. Danzō uses Sasuke's arrival at the meeting place as a chance to escape. Ao pursues him. The Fifth Mizukage battles Sasuke and nearly kills him, but he is saved by Zetsu's technique. Ōnoki uses his Dust Release technique and seemingly kills Sasuke. As the other Kage arrive, Madara reveals himself at the summit, with an unconscious Sasuke on his shoulder, and says he wants to tell them about his Eye of the Moon Plan.
