The majority of  oni  are giants, though less common are goblinoid, kenku, and reptilian  oni . Of course, as shapechangers  oni  magi can alter their appearance to infiltrate other societies and work their way into positions of leadership and influence. They may take  command  or serve leaders of their less-intelligent giant kin such as ogres, but some prefer to become lone marauders who hold villages hostage, demanding regular tribute in the form of gold, food, or captives, lest they take more than they ask.'
