Power - Episode 1

is episode 290 of the Naruto: Shippūden anime.

Summary
The reborn Team Kakashi is sent out on a mission by Tsunade to a location know as "The Hole" to investigate an incident. Regretting that she could not assign more people to the mission because of recent incidents elsewhere, the team sets out nonetheless. While there, they split up into two man teams and Yamato and Sai encounter officers from the neighbouring Hachō Village where Shiseru and her team, after finding out who they were, escorts them to their village leader Disonasu. Elsewhere, Sakura and Naruto, who are at The Hole, encounter Kabuto Yakushi who after revealing that he had reconstructed Hidan and reincarnated several shinobi. As a fight ensues, between the two sides as Yamato and Sai rejoin with their team-mates, a flashback of the destruction of the village occurs.
