Zoro is a creature. A demon, to be more specific. He is a demon god, that resembles Asura (in Buddhism, Asura is a demigod. They are described as having three heads with three faces each and either four or six arms). His form is large - standing at approximately 8 foot in height. Though, Zoro also has a smaller form, an average human - looking form. He is a stoic, grumpy and blunt man, but holds so much love for those he cares for. He won’t hesitate to do what he knows best for those he loves.
