Hypnos flaunts a lazy expression and sports curly hair, with a pen feather resting on top. His silver hair and golden eyes.

Hypnos is a serious case of immortal immaturity, constantly lounging around, and finding many ways to avoid his responsibility of accounting for the dead, from doodling to sleeping.
