Plot highlights: Early in the arc, Orochimaru experiments with lightning to create a robotic being. He and Kabuto must evacuate when the robot goes berserk. Itachi and Kisame later find the robot, which Pain repairs before ordering Itachi to use it to capture Naruto. The robot is sent to Konoha, where it hunts Naruto, attacks villagers, and defeats Team Guy. Naruto arrives to stop the threat, and his training helps him fight back. The robot’s cloak is ripped away, revealing a mechanical duplicate of Naruto named Mecha-Naruto. Mecha-Naruto begins draining Naruto’s Nine-Tails chakra, weakening him, until Kakashi and Yamato intervene, with Kakashi distracting the robot using Lightning Blade and Yamato saving Naruto.
