Lieutenant Rose Copen is a spy and demolitions expert for the Australian navy, and is Allison Mann's lover. She wears an eye patch after losing an eye in a firefight with a Tasmanian woman. She joins Yorick Brown, Agent 355, and Dr. Mann on their quest to rescue Ampersand. Her true agenda becomes clear after Dr. Mann's mother stabs her with a jian: delirious, she confesses that she had been sent to spy on them. However, she maintains that she is in love with Allison, goes AWOL, and later agrees to be impregnated with Yorick's clone for the benefit of Allison's research.
