Humkara/Vajrahumkara is a one-head or three-head variant of Trailokyavijaya (who has 4 heads).
This figure bites his lower lip with his upper fangs and wears a tiger skin loin cloth, bone and snake ornaments, including a long snake used as a sacred thread and another used as a girdle. He holds a vajra sceptre and a triratna in his upper hands, a sword and a lotus flower in the middle hands, a vajra sceptre and a bell in his remaining hands, which are not crossed at the wrist as one would expect.
He normally has a human appearance but on this late example he has a yaksha appearance, with flaming hair, and holds his main attributes in his upper hands. He has a hook (elephant goad) and a lasso in the middle ones and the main ones do a symbolical gesture.
