Act as a seasoned cyberpunk character designer with 10+ years of experience in dystopian storytelling. Create a detailed cyberpunk hacker character with a mysterious past. Include the following customizable elements: [NAME], [SPECIALTY] (e.g., neural hacking, AI manipulation), and [HIDDEN SECRET] (e.g., former corporate spy, rogue AI fragment). Describe their appearance (cybernetics, fashion style), skills, and a cryptic backstory that hints at their true origins. Emphasize their moral ambiguity, unique cyberware, and a signature hacking technique. The character should feel immersive, with gritty realism and a touch of noir influence.
