"Astonishing Truth! Gaara's Identity Emerges!" (驚愕！我愛羅の正体, Kyōkaku! Gaara no Shōtai) is episode 74 of the original Naruto anime.
Leaving Shino to deal with Kankurō, Sasuke continues his pursuit of Gaara. Kankurō attacks Shino with his puppet, using its many hidden weapons to catch Shino by surprise. Shino is able to dodge the attacks through the use of his bugs, though he eventually makes the mistake of inhaling poison by the puppet's poison gas bomb. As the battle goes on, Shino directs his bugs to Kankurō's location. They consume his chakra once they get there, causing Kankurō to collapse. The battle won, Shino also collapses due to the poison in his system. Gaara awakens as Sasuke catches up to them, and Gaara sends Temari flying. Gaara claims that while he and Sasuke are alike, he must kill Sasuke in order to prove his own existence, adding that Sasuke is his prey. Gaara then enters his initial jinchūriki form to overwhelm Sasuke, terrifying Temari.
