Bokoblin

They are more common in the Southern and parts of the Eastern areas of Hyrule Field, and are prominent in Faron Woods. They are Imp like in appearance, and are not very intelligent. They are first encountered in their blue-skinned variant, which carries a small stick and is easily felled. Later, they will appear purple, and wield swords. Purple Bokoblins are surprisingly resilient, taking very much abuse before death. They share their blue counterpart's mental drawbacks, however. It is possible that the two colors of the Bokoblin could indicate different genders, however this is merely speculation.
