Their arms & legs are covered with coarse hair. Their hands end in dirty, thick talons.
Their skin is normally red, but other colors including green, black, orange, and purple have been seen.
There are also blue-skinned oni, although these are more commonly known as ogre magi.
Their dress imitates that of the local human population,
although their clothing and equipment are more rugged and dirty than that of their human counterparts.
