Background

Mobius originates from the Honkai Impact 3rd Pre-Civilization era, where she was a leading biologist and a principal developer of the technology behind the Thirteen Flame Chasers alongside Dr. Mei. Her specialty is biotechnology, and An Xiu considers her intellect superior to his own. 30

An Xiu manifests her as a blank avatar without Flame-Chaser powers, but she retains the knowledge needed to identify research opportunities across worlds. Upon appearing, she immediately offers her service to him and chooses the One-Punch Man world as the most suitable base for early development. 30 31

Appearance

Mobius is a petite girl with a deliberately unsettling, serpentine presence. Her formal attire and composed manner contrast with the danger implied by her gaze and movements. 30

• Long, naturally curly emerald-green hair.
• Snake-like vertical pupils.
• Black-and-green formal dress.
• Frequently described with a dangerous aura and snake-like flexibility. 30

Personality

Mobius is intensely curious, pragmatic, and ruthless in pursuit of scientific progress. She treats unusual organisms, powerful beings, and even political crises primarily as research opportunities. Monsters, Terra's races, Dragonia, Stands, Demon Gods, and Path power all attract her interest as potential subjects or materials. 31 63 158

She is manipulative and unconcerned with the autonomy of her test subjects. Her improved Monster Cells include genetic obedience failsafes, and she uses Talulah, FrostNova, and Patriot as both experimental subjects and controllable political assets. 33 34

Despite her predatory manner, Mobius is completely loyal to An Xiu. She identifies all avatars as extensions of his will and insists that his commands take priority over her own decisions. She also refuses to use experiments that could produce dangerous consequences for him. 31 34

Abilities & Skills

Biotechnology and Flame-Chaser Surgery

Mobius is a premier biological researcher capable of modifying living beings, integrating foreign genes, and performing Flame-Chaser surgery.

• Performed Flame-Chaser surgery on herself using the Sasha Gene. 31
• Developed the procedure used to augment An Xiu's forces, including Lapland and Aponia. 58 197
• Extracted, cultivated, and modified Kryptonian genetic material into a factor suitable for Flame-Chaser surgery. 39
• Determines that genetic material derived from An Xiu can retain a connection to him after transplantation, allowing him to influence the recipient's behavior and thoughts. 55
• Notes that An Xiu-derived genes remain stable inside their host but become highly aggressive after leaving that body and entering another organism. 123

Monster Cell Research

By studying One-Punch Man's monsterization process, Mobius creates stabilized Monster Cells that unlock potential without forcibly mutating users into monsters.

• Stabilized Monster Cells remove the physical mutations associated with ordinary monsterization. 31 32
• Ordinary versions can be mass-produced but are generally limited to one use per person. 32
• An ordinary person using a standard Monster Cell and Limit Break Potion can reach roughly Tiger-level, comparable to mid-to-lower B-Class or mid-to-upper A-Class hero strength. 32
• Improved Monster Cells can drastically amplify high-potential subjects such as Talulah, Patriot, and FrostNova. 33 35
• Improved versions contain a genetic failsafe: consumers cannot disobey Mobius or An Xiu, and Mobius can decide their life or death. 33

Limit Break and Ouroboros Potions

Mobius develops pharmaceuticals that raise a subject's potential and racial ceiling.

• Limit Break Potion — allows the user to surpass their original racial limits and gain a higher potential ceiling. 32
• Ouroboros Potion Type I — combines and improves the effects of the Improved Monster Cell and Limit Break Potion. 55
• Ouroboros Potion Type I is stronger in a single use but cannot raise a user to God-tier. 55
• Her Oripathy cure medicine is successfully produced and tested on Sarkaz laborers through Rhodes Island. 96

Biological Weapon Development

Mobius applies her research to mass production and military enhancement.

• Clones Wendigos from Patriot's lineage, maturing them in seven days at roughly 200 per batch. 35
• Assists in developing the Giant Wendigo program and related military biotechnology. 92 132
• Modifies Step-away Maidens with transplanted Mangekyō Sharingan: Kamui, allowing them to use spatial distortion, intangibility, Kamui space, and Susanoo. 138
• Studies the Authority of the Herrscher of Restraint with Makima, enabling Vill-V to install a simplified Restraint Barrier in a mech. 132

Cross-World Research

Mobius actively incorporates materials and power systems from other worlds into her work.

• Researches the Kryptonian Bloodline and later identifies its exceptional compatibility with the Factor of Light. 31 123
• Her Factor of Light research enables An Xiu to establish a self-reinforcing cycle between light energy and Kryptonian genetics, raising him from surface-level to several times star-system-level. 127
• Studies Redstone energy with Vill-V, though she struggles to integrate its properties into living organisms. 93
• Receives Mangekyō Sharingan: Kamui and the Factor of Light for research. 117
• Declines to research Madoka's Law of Cycles because its multiversal scale exceeds her and Vill-V's ability to meaningfully analyze; instead, she focuses on the more approachable power of Miracle. 157 158

Research Operations

• Uses the Holy Grail to acquire a fully equipped biological research base and substantial legal funds in the One-Punch Man world. 31
• Selects City A for the base because of its development and relative safety. 31
• Registers a biotechnology company, recruits employees, and procures powerful monster tissue for experimentation. 31
• Becomes a major shareholder of the Hero Association. 55
• Expands World Serpent Biotech into a major private enterprise producing medical supplies, daily necessities, and biotechnology products while holding stakes across related industries. 71
• Transfers the research base from the One-Punch Man world to the Honkai: Star Rail world, where she and Vill-V begin studying Path power. 157 158

Relationships

• An Xiu — Her master and the central object of her loyalty. Mobius serves his objectives, protects him from dangerous experimentation, and treats his commands as absolute priority. 30 31 34
• Vill-V — Fellow Pre-Civilization scientist and research partner. The two collaborate on Redstone, mechs, Path power, and the research base's broader technological projects. 86 93 132
• Makima — Collaborator in political control and biological research. Makima helps Mobius dominate wealthy elites and provides the Herrscher of Restraint authority for study. 55 132
• Talulah — Experimental subject, controlled asset, and political proxy. Mobius strengthens her with improved Monster Cells and supports her rise as a ruler in Terra. 32 34
• Patriot and FrostNova — Reunion leaders enhanced through Mobius's improved Monster Cells and used in her Terra development plans. 33 35
• Pre-Civilization Mobius — Her past counterpart, recruited after being shown future technology and the scale of An Xiu's forces. The two work together on research afterward. 191 192
• Bianka — Assistant to Pre-Civilization Mobius, who advises caution regarding the mysterious reagent but ultimately supports her decision to investigate it. 190
