"The Complete Ino-Shika-Chō Formation" (完璧な猪鹿蝶!!, Kanpeki na Inoshikachō!!) is episode 274 of the Naruto: Shippūden anime.
Attacking his teacher for calling him fat, Chōji stops midway before landing the blow, stating that he was unable to harm his sensei. Not given the same options, Asuma deflects his old chakra blade thrown at him by Shikamaru before being forced to attack Chōji. Deflecting the attack, everyone is shocked to see Chōji reacting before realising that Ino had transferred her consciousness into Chōji. Calling for the young man to recognise the situation they were in, Ino tells him to remember what those earrings symbolised before Asuma unleashes another searing cloud of ash which Chōza uses his body to protect them from. Calling for his son to start acting like the sixteenth head of the Akimichi clan and the oath he took to protect as such. Recalling the oath he had taken, Chōji grows his butterfly wings, surprising everyone. Shocking his comrades with the amount of weight he was losing they begin to worry believing that he had ingested one of the Three Coloured Pills, Chōza corrects them saying that Chōji was instead using the clan's calorie control technique and would be fine. Deciding that he was no longer needed there, Chōza left apologising that his son had been a hindrance thus far and that this would no longer be the case. Preparing the Butterfly Bullet Bombing technique, Chōji is joined by his comrades as they prepared their revised attack. Resting on Shikamaru's back, Ino uses the Mind Clone Switch Technique to take control of two fallen White Zetsu Army clones and engages Asuma in battle. Supporting her, Shikamaru uses his shadow to rob Asuma of a foothold, leaving him open for Chōji to punch Asuma into a nearby rock formation. Before being sealed, Asuma tells the trio that their formation had been perfected — something he states that he couldn't say before. Motivated, Chōji grows to gigantic proportions and declares that he was going to end this battle and required their help to which they emphatically agree.
