Leshy appears to be a bagworm moth caterpillar, with a round head covered in thick green leaves. Several thin black branches protrude from either side of his head like horns. His eye had been gouged out by The One Who Waits, thus they are covered by a set of thick, bloodstained bandages wrapped around his head. Black ichor can be seen oozing out from beneath the bandages. Like the other bishops, Leshy wears a long black robe with golden trimmings that covers the rest of his body.
