Mykes closely resembled Humans, with the exception of a fairly pale complexion and facial differences. Their hair was often a shade of black or dark brown, with eye colors typically ranging anywhere from dark blue to dark purple, dark green, dark brown or dark gray. The species had distinctive fleshy "chin tufts" at the sides of their chins, giving them their unique look. Their writing system was similar to the Sith alphabet.
"The Written Word," a hyperspace article, linked their writing system to that of the Sith.
