The second-to-last of the Pleiades Series built by an Earth native known as Stein, Merope is technically classified as an “Android Rescue Bot.” While not Masters in the traditional sense, she and her sisters were specifically built to be powerful enough to stand with them in combat. The Pleiades Series of androids are programmed to protect Masters at all costs, and are unable to act without direct orders. As they are given only basic AI and personality function, Merope often makes people uncomfortable with her lack of emotion, inability to understand humor, and direct, formal way of speaking.
Despite her lack of human characteristics, she does occasionally exhibit curiosity about mortal functions, such as eating and drinking. Merope often sees herself as strange middleground between Synd and humans. She called herself the Fallen Star, and believes she is incomplete. She yearns, despite her rigid programming, to find a place amongst existence where she will be recognized at equal standing. Perhaps this is why she has outfitted herself with so many armaments, as to match any Master on the battlefield.
