Mobius has an unsettling air surrounding her, her doll like appearance and green snake like eyes cause people to fear and avoid her. Described by Klein as a "pure being, a pure seeker and a pure evil", once Mobius sets herself a goal, she will pursue it no matter what, even if it is dangerous or outright immoral, including experimenting on others without their knowledge. She also believes that humans can defeat Honkai through evolution, having humans fuse with Honkai to create a stronger race.
