Background / History

The childhood record observed through Liu Bai’s simulation begins with Mobius recognizing his blurred Spirit form immediately after her birth. She initially dismissed him as a fool and grew up “despising” him, yet their constant companionship caused her to gradually acknowledge his existence 4.

At six, Mobius lost the ability to see Liu Bai directly, which left her frightened despite her intelligence and early maturity. She was already studying high-school material at that age and habitually called him “Stupid Spirit” 5. Her mother died when Mobius was nine, while her father’s Honkai disease and worsening mental state led him to abuse her. Liu Bai protected Mobius from the violence, and she ultimately left home with him after deciding to sever ties with her father 5 6.

Mobius supported herself and continued her studies after leaving home. By eighteen, she had become an accomplished biologist. Her two central ambitions were the evolution of humanity and creating an artificial body through which Liu Bai could live physically 6. Although Liu Bai disappeared at the end of the simulation, Mobius continued to regard him as her husband 52.

She reunited with Liu Bai after Fu Hua helped create a Soul Steel vessel for him. Their conversation allowed Mobius to confront her resentment over his disappearance; she accepted his feelings and chose to remain with him despite knowing he might vanish again 55 56.

As an elder of Moth Chasers to Fire and head of its Biology Department, Mobius became a major contributor to anti-Honkai research. She developed the Fusion Warrior path, researched Honkai disease and human modification, recruited scientific talent, and pursued increasingly dangerous solutions to humanity’s survival 120 393 439.

Appearance

Mobius is a tall, green-haired woman with a composed but intimidating presence. She is recorded as 173 cm tall and approximately 54.7 kg 475.

• Long green hair, often left loose behind her 332 393
• Serpentine eyes that reinforce her predatory demeanor 452
• Commonly wears black dresses or laboratory attire 52 393
• Can restore herself to an eighteen-year-old body through molting 486
• Has also appeared in a temporary child form during her Collapse-related testing 508

Personality

Mobius is brilliant, proud, and intensely pragmatic. She values obedience and usefulness, dislikes incompetence, and readily evaluates people by their potential. Her arrogance often creates friction with other researchers, but she is genuinely willing to cultivate talents she recognizes as exceptional, as shown by her interest in Mei, Vil-V, and Su 123 393 433.

Her scientific drive is uncompromising. Mobius conducts research others consider inhumane or reckless, including experimentation on Honkai disease patients and self-administered genetic surgery. She accepts personal suffering as an acceptable price for knowledge and progress 376 442.

Around Liu Bai, Mobius becomes noticeably more playful, vulnerable, possessive, and jealous. She considers herself the first person to have met and loved him, resents perceived romantic rivals, and is determined not to abandon either him or her career 123 124 125. Despite this possessiveness, she explicitly states that her jealousy should not be based on Liu Bai’s unwillingness 56.

Abilities & Skills

Biology and Medicine

Mobius is among the foremost biological researchers of her era.

• Became an accomplished biologist by age eighteen 6
• Was recognized as a leading figure in biology before joining Moth Chasers to Fire 119
• Researches treatments for Honkai disease and Death Soldier transformation 51 393
• Can teach medical knowledge and personally train students such as Su 433
• Performs and directs complex surgeries under extreme conditions 442

Fusion Warrior Research

Mobius is the principal architect of the Fusion Warrior path, which seeks to merge humans with Honkai Beast factors.

• Developed the “Fusion” path as one of humanity’s primary anti-Honkai approaches 468
• Worked to improve early anti-Honkai serum and Fusion Warrior technology 439
• Understands the compatibility, physical adaptations, and side effects associated with Honkai Beast genes 443 473
• Believes controllable Honkai Beastification may be the future of Fusion Warriors 487

Shesha Fusion

Mobius implanted Shesha genes into herself to test Liu Bai’s damage-nullification ability and validate her own theory.

• Endured severe pain and internal-organ damage while remaining conscious enough to direct the operation 442
• Gained rapid self-repair and immortality after the modification succeeded 443
• Received a major but unquantified increase in physical strength 443
• Her body may shed skin as part of its snake-like modifications 443
• Despite her enhancement, she initially lacked professional combat experience and was not assigned to frontline operations 458

Molting and Collapse

Mobius’s Shesha-derived physiology allows drastic bodily restoration, but repeated deaths carry consequences.

• Can molt from a dead body and regenerate into a younger state; she restored herself to age eighteen through this process 486
• Repeated deaths can trigger a “Collapse” state of Honkai Beastification 509
• She can forcibly halt Collapse through willpower and believes it can become a controllable combat technique 509
• She considers Collapse dangerous even when it is useful 509

Relationships

• Liu Bai — Her childhood guardian Spirit, lifelong companion, and the man Mobius considers her husband. Her goals of human evolution and creating a body for Liu Bai have defined much of her research 6 52 56.
• Fu Hua — Initially a romantic rival for Liu Bai’s affection, later an ally with a relationship between upright rivalry and close friendship. Hua helped reunite Mobius with Liu Bai 52 56 432.
• Dr. Mei — A recruited young genius, scientific collaborator, and rival turned defensive ally. Mei led Mobius’s Shesha-gene surgery 123 124 442.
• Elysia — Mobius’s close friend and frequent rival. Their relationship is defined by mutual teasing, competition, and genuine concern for each other’s well-being 415 445 481.
• Gray Serpent — A surviving product of Mobius’s artificial-flesh experiments. Mobius rescued him, named him, and later took interest in his independent development 494 496.
• Vil-V — A mechanical genius Mobius initially looked down on, then came to recognize as a peer specializing in mechanics 393.
• Su — A junior whom Mobius agreed to teach medicine; she considers him promising enough to expose him to advanced research 433.
• Klein, Danzhu, and Cangxuan — Members of Mobius’s laboratory circle who assist her work and witness her softer behavior around Liu Bai 434 442.

Story Role / Major Arcs

Mobius: Childhood

Mobius’s early life establishes her bond with Liu Bai. The simulation follows her from birth through the loss of her mother, separation from her abusive father, independent education, and rise into biology by age eighteen 4 5 6.

Reunion with Liu Bai

After years of separation, Mobius encounters Liu Bai through his Soul Steel vessel. Her initial shock gives way to acceptance, and she chooses to pursue a future with him while acknowledging his connections to others 55 56.

Moth Chasers to Fire Research

As head of biology, Mobius becomes central to research on Honkai disease, Fusion Warriors, artificial bodies, and anti-Honkai technology. Her work makes her indispensable to Moth Chasers to Fire even as others fear her methods 376 393 439.

Shesha Experiment

Mobius uses Shesha’s regenerative biology as the basis for self-experimentation. Her successful fusion grants immortality and makes her one of the organization’s enhanced combat-capable members 442 443.

Finality Preparations

Facing humanity’s likely defeat by the final Herrscher, Mobius restores herself through molting, analyzes Fusion Warrior Collapse, and participates in plans to preserve civilization through shelters, hibernation, and other contingencies 486 495 509.

Notable Quotes

“I want humanity to evolve. Although it's just a childhood dream, it's also been my constant goal.” 124

“For me... just being able to see you again is enough...” 56

Trivia

• Mobius could remember events from her own birth and began studying high-school material by age six 5.
• Liu Bai’s completed childhood simulation with Mobius reached 262% compatibility 6.
• Mobius submitted the name “Herrscher” for the unprecedented humanoid Honkai creatures, and the designation was approved 391.
