Deidara is a member of the Akatsuki in Masashi Kishimoto's Naruto series, introduced in the manga and later in the Naruto Shippuden anime. An artist who molds explosive clay into animals and objects, he triggers the detonations with the word Katsu, treating each blast as art. The shout became one of his most quoted lines among fans, clipped from episodes and shared across YouTube and soundboards for edits and memes. Its clear link to a coming explosion keeps it instantly understandable even outside Naruto fandom.
