This massive, obviously slow minded orc is covered in scars from head to toe. Most of the old wounds seem to have been caused by a blade or lash, some by fire and acid.  

These scars and the bloodstained chains around the beasts wrists and ankles, are clear signs of a past spent in slavery.

Someone has written something on the orcs chest, the letters almost washed away by sweat and occasional bloodstain: "If this orc is suffering from an acute case stupidity or is acting violently when not supposed to, please do not hesitate to beat him into submission or cast a minor intelligence boosting spell on him."
