Captain Kunne's First Officer on the Catian mothership. Though she projects an image of being indecisive, she's actually a very competent officer. She appears to have a complex about her small chest size, which seems to be a minority among Catians. When Captain Kunne is incapacitated in a Dogishuan attack, Melwin is unable to assume control of the Catian mothership since command codes only transfer to her if the Captain were killed.
