Power - Episode 1 (「力-Chikara-」episode1) is episode 290 of the Naruto: Shippūden anime.
Tonika Village, a small town in a location known as "the Hole", is attacked by several reincarnated shinobi. Two young children, Leo and Miina, are rescued from their burning home by their teacher Dokku, who leaves them in the forest outskirts while he attempts to rescue more survivors. While the two hide, Kabuto Yakushi walks through a nearby clearing, controlling the reincarnated shinobi using a portable wooden go board and several white stones. After a moment he grins and withdraws the board and pieces into his cloak, then leaves. In the morning, the two children set out for Hachō Village as Dokku instructed. That evening, a severely wounded Dokku catches up with them, with three orphaned survivors in tow: Faz, Lando, and Sora. Some time later, the reborn Team Kakashi is sent out on a mission by Tsunade to investigate the 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, with Yamato and Sai encountering officers from the neighbouring Hachō Village where Shiseru and her team, after finding out who the Konoha shinobi were, escorts them to their village leader Disonasu. Elsewhere, Sakura and Naruto, who are at the Hole's water spring, encounter Kabuto. Kabuto reveals that he had reconstructedHidan and reincarnated a small army of shinobi, and is using the water of the Hole to conduct experiments on genetic reconstruction. A fight ensues between the two sides as Yamato and Sai rejoin with their team-mates, and Naruto is dragged deep underwater by Kabuto's giant Clone Snake serpent.
The DVD version of this episode is a director's cut, which differs significantly from the original TV broadcast version. When originally broadcast the episode's structure was altered so that it opened with Team 7 departing for their mission, while the destruction of Tonika was presented as flashback during the latter half of the episode, after Naruto was dragged underwater by the giant serpent.
The director's cut includes a scene that was removed from the TV broadcast, in which Kabuto controls the reanimated shinobi destroying Tonika using a go board and stones while Leo and Miina hide nearby. Despite it not being used in the broadcast episode, shots from this scene were still featured in the preview aired alongside the previous week's episode.
