Toby escapes while Deidara prepares his C4 explosive, a giant replica of himself. When detonated, it emits a cloud of microscopic bombs, which, from within, undermine the living organisms that inhale them. After Sasuke apparently gives in to his inevitable fate, Deidara begins to triumph. However, he is attacked from behind by Sasuke, who saw the miniature explosives scattered through the air with his Sharingan and avoided them by using genjutsu and creating the appearance of his death. Sasuke realized that the Deidara he attacked turned out to be a claymore clone. Deidara was able to recognize genjutsu thanks to years of training dedicated to countering Sharingan illusions directly.
