This beadsprite is the Wizard enemy from Final Fantasy. In later re-releases it is called the Piscodemon. I think the spelling “Pisco” is intended to be a reference to “Pisces” like fish, as it has an octopus face. These dudes were found in the Marsh Cave guarding the crown that you needed, and were fairly tough, and could knock you out quick. If you had a black mage with LIT2, they were dispatched in short order.
I liked the way this one turned out. The robes look good on it.
