Short, wirey, and obsessed with her appearance, Rita Prestin takes great pride in her work as the chief medical officer of Omni-Med. Often seen as somewhat harsh and to-the-point, she is certainly unequaled in the medical field, and has used her talents extensively upon the world of Rubi-Ka. Despite her age, she maintains the appearance of a woman in her mid-fourties, shoulder-length black hair strikingly streaked with bits of silver. She appears to wear quite a bit of makeup, and has been seen to be rather vain about her appearance, often using medical technology to enhance her looks.
