Oomalaat was a Force-Sensitive Twi'lek who worked as a professional killer. Not much is known of her early life; she claimed to be 21 years old and to have been born on Ryloth. She was likely sold into slavery at some point and trained as a professional dancer. Escaping, she turned to a life of crime, using the Force to supplement her abilities. Despite using only a simple staff, she proved to be a very adept and dangerous killer. Rather then being bound to any one organization, she instead worked as a freelance hitman.
