Ulyanov wore his full face helmet all the time except when he was back on the base. The helmet was part of his signature appearance. He wore the mask not to look cool, or use it as armor. He wore it to keep himself alive and cover up his horrifying face.
A man with a face even a mother could not love sat behind a desk and fiddled with his equipment. His face looked hardly human; large patches of skin had gone, while metal grew within his exposed muscles and bones. Electronic circuits were connected to one of his eyeballs, preventing it from dropping off. A metal tube had replaced his nose. Another tube attached to a cylinder next to the desk. What was left of his teeth was just a row of metal.
Under the helmet, Ulyanov's real, hidden face was that of a cyborg—a combination of man and machine. It was so strange and terrifying that even Hao Ren was shocked despite having seen many peculiar things before.
