A New Formation: Ino–Shika–Chō!

is episode 145 of the original Naruto anime.

Synopsis
Team 10 tells Naruto that they will take care of the brothers, and use their combined skills to immobilise them. Naruto leaves to catch up to Iruka, who is fighting Mizuki in a building used to test Academy instructors. It is revealed that Iruka and Mizuki are childhood friends, although Mizuki only hoped to get close to the Hokage. Mizuki reveals that he has become stronger and learned new techniques while in prison. Meanwhile Ino, Shikamaru and Chōji form a new formation. Mizuki sets paper bombs on Iruka and blows up the building.

Trivia

 * There is some inconsistency in this episode concerning Shikamaru's Shadow Imitation Technique, as Ino takes control of Raijin and punches Fūjin with Shikamaru being left unaffected (it is previously stated as Shikamaru has control of Gaara and Naruto punches Gaara in the face that punching Gaara while Shikamaru has hold of him with the shadow position will also effect him).
