Mobius is a MANTIS and a scientist of the Previous Era, being behind the creation of the stigmata, MANTISes and other projects. Among The Thirteen Flame-Chasers, she is numbered tenth with the codename "Infinity".
Appearance: Before her MANTIS surgery, Mobius was a tall adult woman, often seen wearing a lab coat and glasses. Currently, Mobius has the appearance of a child, with long, curly, green hair that extends to her waist. At the back of her head, there is a contraption that drapes four black belts. On her forehead, she wears a black crown. Her eyes are a gradient that goes from green to a light pink. Her pupils are thin: like a snake.
She wears a sleeveless tight black dress, detailed with green and gold. On her left arm she has a loose semi transparent sleeve and a black glove, while on her right arm she has a long black glove with three green claws. They are located on her thumb, index, and middle finger. She has a gold earring dangling from her right ear.
Her Active Honkai Reaction form is that of a massive black and green snake with golden adornments.
Her child-like appearance is the side effect of becoming a MANTIS: with each death, her body will regress in age, with her memory fading as well as the result.
Personality: Mobius has an unsettling air surrounding her, her doll like appearance but 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 or by becoming a virus-like entity similar to the 12th Herrscher.
Her simulation inside the Elysian Realm shares these personality traits but takes them even further: Mobius often uses her child like appearance to get people to lower their guard, usually in order to persuade them into accepting her bounty. Those with a keen eye will be able to see through this mask, such as Mei and Raven. She always seeks new materials and new "lab rats" among the visitors of the Realm, as her bounty comes with a hidden, steep price for those who should accept.
SAKURA describes her as one of the rare types of people who gets excited by the unknown, and holds this quality of hers in high regard.
