Dr. Xeno, a young adult with meticulously styled long, light-colored hair, possesses thick eyebrows, large dark eyes without visible irises, and heavy bags, giving him a raccoon-like appearance. His small nose and mouth lack visible lips. Notably, his extremely prominent forehead showcases petrification scars in the shape of an 'X', which remain as a light outline even after his second revival, adding a touch of intrigue to his enigmatic visage.
