Late for the Show, but Ready to Go! The Ultimate Secret Technique is Born! (だてに遅れたわけじゃない!究極奥義・千鳥誕生!!, Date ni Okureta Wake Janai! Kyūkyoku Ōgi - Chidori Tanjō!!) is episode 67 of the original Naruto anime.
With Gaara unable to move while within his shield, and Sasuke unable to break through its defence, Sasuke decided to use his new technique: the Chidori. With it, Sasuke was able to pierce Gaara's shield, stopping his transformation, and becoming the second person to ever injure Gaara. At that moment, Kabuto Yakushi used a genjutsu to put the audience to sleep, signalling the start of the invasion of Konoha.
