Create an ultra hyper-realistic 8K neon-cinematic portrait of a cosmic digital clown-trickster, a bald man with a pristine shaved head glowing under ultraviolet light, his fine beard sharply illuminated by neon edges. His expression is a hypnotic fusion of:  Riddler s mischief,  Joker s menace,  Mandrake s mystical theatricality,  Chaplin s clever innocence,  Buster Keaton s unbreakable composure,  and the silent intensity of a cosmic acrobat preparing a trick. His skin is partly translucent, showing living circuitry, nanotech fibers, and bioluminescent tattoos shifting in real time. His eyes shine like digital supernovas, filled with purple-pink-blue plasma code spirals. He wears a futuristic, UV-reactive circus suit:  neon purple coat with turquoise edges,  lime-green accents like riddler glyph filaments,  glowing circuit-ribbons along his arms,  tribal fractal ornaments merging with cyberpunk patterns,  subtle cosmic dust sparkling across the fabric. Pose: theatrical and unmistakably jester-like. He stands in mid-motion, juggling digital light orbs, floating crystalline glyphs, quantum fractal cubes, and UV plasma ribbons. His fingers leave behind luminous trails, each movement carving holographic sigils in the air. Background: A massive digital cosmic circus, with infinite neon arches, glitching holographic banners, solarpunk crystalline flora, art nouveau fractal gates, and spinning rings of sacred geometry hovering overhead. Lighting: deep UV purple, electric blue, magenta, cyan glows, volumetric beams, refractive halos, glitching light distortions. Mood: psychedelic, neon-mystical, elegant, futuristic, cosmic, chaotic-beautiful.
