Tso Lan's appearance seems to be based on an insect, as he is four-armed and has pincers. He has light grey skin and the front of his face is dark grey. He has a long ponytail and a long tongue that is always sticking out. Tso Lan, along with Tchang Zu, is one of the only two demon sorcerers that are fully clothed. He wears a red and purple outfit reminiscent of a Chinese nobleman.
