"Create a pixel-perfect sprite of Sans from Undertale, capturing every canonical detail. Show Sans with a symmetrical skull face, empty black eye sockets with no glowing or blinking effects. His expression is a relaxed, confident smile with no eyebrows or additional facial markings. Sans wears his classic blue puffy jacket with a grey hood lining, a plain white t-shirt underneath, iconic black shorts with two white vertical stripes on each side, and pink slippers with visible details. His posture is casual with hands in pockets, standing straight with legs slightly apart. The pixel art style must replicate the original game's resolution, shading, and color palette exactly. The background should be transparent or a solid neutral grey. No animations, glowing effects, or non-canonical features. Emphasize faithful recreation to game sprite for authenticity." See more
