90s Anime Snake Sage

A retro 90s anime style screenshot, cel animation aesthetic from early Naruto era. A young man transformed into a snake-like sage form, closely resembling Kabuto Yakushi. He has a distinct elongated lean facial structure and sharp features, combined with pale scaled skin, sharp slitted snake eyes with purple pigment markings around them, and small horn-like scales on his head. He is wearing his signature round black-rimmed glasses. He wears a dark, tattered rogue ninja cloak. He is captured in a dark, ominous underground cavern or Orochimaru's hideout, surrounded by stone walls and faint glowing liquid. Muted retro color palette, visible film grain, soft chromatic aberration, hand-drawn sharp line-art, 1990s anime OVA aesthetic, cinematic nostalgic lighting.
