This episode is the climax of one of the most iconic battles in the series: during the Chūnin Exam preliminaries.
Despite the onslaught, Gaara survives by using his sand gourd to cushion his fall. He retaliates with his Sand Binding Coffin , crushing Lee’s left arm and leg.
Lee enters a state where his skin turns red and his speed becomes superhuman, allowing him to bypass Gaara's defenses and land the devastating Reverse Lotus .
