Battle Formation: Ino–Shika–Chō!! (無敵のフォーメーション!いのシカチョウ!!, Muteki no Fōmēshon! Ino–Shika–Chō!!) is episode 33 of the original Naruto anime.
Team 10 battles the Otogakuregenin, and Ino Yamanaka possesses Kin Tsuchi, rendering both of them unable to fight. However, the Oto genin still manage to hold their own. Just as Rock Lee's team-mates appear to join the fight, Sasuke Uchiha awakens, the cursed seal given to him by Orochimaru engulfing him. Noticing Sakura Haruno's wounds, Sasuke begins attacking Zaku Abumi in retaliation, eventually breaking both of his arms. As Sasuke turns his attention to the final Oto genin, Dosu Kinuta, Sakura thinks to herself that this is not the real Sasuke and that he is somehow possessed. She then runs to him and embraces him while begging him to stop. Sasuke's curse marks disappear and he falls to the ground. Dosu admits Sasuke's strength, leaves their scroll and retreats while carrying his team-mates, vowing to not run away next time they meet.
This is the third episode to be rated TV-14-V in uncut format.
