Halloween Unicorn is an AI portrait generator that turns your photo into a Halloween unicorn portrait in about a minute. Upload a clear, front-facing photo and choose from 34 looks across five categories, from Skull Paint Studio and Midnight Black Unicorn to Pastel Zombie Unicorn and a range of pet looks, and the generator keeps your face while rebuilding everything around it in the chosen style. Single-subject looks work best as profile pictures, and a built-in avatar crop lets you centre the face and download at 512 or 1024 pixels; couples and duo looks are also available for two-person photos. Results are for personal use, and the site asks you to label published images as AI-generated. Creating an account is free, but each generated portrait costs one look from a one-time pack: Solo at $2.99 for five looks, Party at $6.99 for fifteen, and Haunted House at $19.99 for eighty, with unused looks that never expire and no subscription. The tool is for adults only and cannot be used with photos of children.
