Gengar, the Pokémon ghost-type creature, fills the frame in an extreme close-up on a diagonal tilt, rendered with a fuzzy fur-like violet texture instead of smooth skin. His pointed ears sweep back, narrowed mischievous eyes with slit pupils glint pink beneath a heavy brow, and a massive wicked grin stretches wide, its teeth reimagined as glittering gold-and-black gemstones that burst with brilliant white four-point star flares. A broad hot-pink tongue lolls out of the magenta mouth interior, catching neon light, while electric blue rim highlights trace the violet fur against deep black shadow. A single four-point star hangs in the black void above his head and blue mist swirls beneath the jaw. The lighting is a neon glow treatment with incandescent sparkle accents, captured in an extreme close-up diagonal composition filling the vertical frame. The aesthetic is a vintage airbrush and stipple poster illustration with risograph grain, a retro trading-card and 90s poster feel, a saturated neon palette of violet, magenta, gold, and electric blue against deep black, and high-detail print texture throughout.
