Iotrans had smooth skin, dark brown to black in color. They possessed a broad, flat nose, no discernible ears, hands with four digits, and two-toed feet. They had distinctive spots on their bald heads, knobby protrusions at their temples, and short, stubby spikes protecting their shoulders, elbows, and hands. Especially talented enlistees in the IPF often became Iotran Bracemen, which tracked down fugitives outside of the Iotran Expanse, often without regard for local laws or for what other species call "jurisdiction"; this often resulted in diplomatic incidents.
