The Sheftu (pronounced "shef-too") are secondary recruits in the Tlak'kahn army. They appear to be transparent and their external skin seems to vary from pink, gray and purple. They have two organ sacks which seem to be connected by nerve synapses. One seems to contain most of their organs and the other one contains their brain. However they do not have any digestive or respiratory system. Sheftu can also take on the form plant life. (INF: "Who Are You?") The Ancients are able to distinguish between someone and a Sheftu impersonating that person.
