Background / History

Mobius became available after Griseo unlocked her identity through the panel. Unlike a simple transformation, Mobius could be manifested as a separate clone-consciousness synchronized with Griseo’s will; the two retain a telepathic connection despite possessing distinct thoughts. 19 20

Her first documented manifestation used her mature form in the forests near the Yeti Squadron’s mine. Griseo later summoned Mobius directly, greeting her as “Grandma Mobius.” 20

Mobius and Sakura subsequently traveled toward Kazimierz, intending to earn funds for Mobius’s studies and investigate the new world’s knowledge. Her interest in Terra’s biology quickly led her to test Maria Nearl’s compatibility, collect samples from her, and perform an unlocking procedure while Maria slept. 64 65

By the time she joined Rhine Lab’s Structural Department, Mobius was running an ostensibly small project alone. She kept a low profile, avoided collaboration with researchers she considered unworthy of her time, and devoted herself to studying Terran technology and Originium infection. 93 95

Appearance

Mobius has long light-green hair and gradient-colored, snake-like eyes. Her manifested forms include a tall mature woman and a smaller childlike form. 20 93 95

• Commonly wears a white lab coat while working. 20 93
• Her mature form possesses night vision. 20
• Her childlike form wears an outfit designed by Eden, including black gloves. 93 94
• She can alter her apparent age and body size to suit infiltration or social manipulation. 64 93 94

Personality

Mobius is intensely knowledge-driven. She considers Terra “fascinating,” prioritizes research over recognition or companionship, and frequently works through the night without rest. She has little patience for people she considers unintelligent, intrusive, or inefficient. 64 93 95

She is manipulative, teasing, and often treats others as useful pieces or potential research subjects. Mobius exploits Maria’s kindness, bargains with Ho'olheyak for favors, and deliberately frightens her when she becomes too curious. 64 65 96 106 124

Despite her clinical language and willingness to experiment, Mobius draws a line at the abuse of children. She openly despises using children as repeated experimental subjects and works to create safer, purpose-built treatments for Ifrit. 93 95 100 117

Mobius identifies herself with Infinity and endless evolution. Accordingly, she views Ho'olheyak’s race’s fixation on reclaiming the past as fundamentally opposed to her own ideals, and regards Seaborn assimilation that destroys human identity as degeneration rather than evolution. 107 223

Abilities & Skills

Identity Manifestation

Mobius exists as an identity unlocked by Griseo and can be independently manifested.

• Can be directly assumed by Griseo as a transformation. 19 20
• Can be manifested as a separate Mobius clone with a consciousness distinct from Griseo’s. 19 20
• Maintains a telepathic connection with Griseo and the other linked identities. 20 64
• Has both mature and childlike forms. 19 20

Scientific Research and Medicine

Mobius is an accomplished researcher specializing in biology, experimental treatment, and Originium-related research.

• Examined Terran physiology and collected samples from Maria Nearl during her first direct contact with a Terran subject. 65
• Independently researched treatments for Originium infection at Rhine Lab. 93 95
• Designed medicine for Ifrit, including pain-relief and body-control treatments tailored to her condition. 100 117
• Conducted a successful treatment experiment on an infected volunteer; the volunteer improved significantly, though Mobius deliberately did not fully cure her for safety reasons. 115
• States that she can cure Originium infection, but lacks the manpower and environment to implement the method on a wide scale. 128

Honkai Energy Resistance

The energy within Mobius’s body prevents Originium particles from invading her and can clear the immediate area around her.

• Originium dust and particles cannot affect her unless her Honkai energy is depleted. 98
• Can consciously regulate the energy leakage that produces the unusually “clean” space around her. 97 107
• Warns that an uncontrolled eruption of her internal energy would have catastrophic and irreversible consequences. 108

Black Mud Manipulation

Mobius controls black mud marked by a faint green glow for infiltration, transport, and combat.

• Spread it through Rhine Lab while precisely avoiding surveillance cameras. 93
• Used it to enter and leave Ifrit’s room undetected, sinking into it to disappear. 95
• Can use it to seize and crush opponents with giant claws. 223
• Formed dozens of spears from it to impale and immobilize Quintus. 223
• Used it to pull Ho'olheyak through a closed office door and deposit her inside. 131

Artificial Honkai Form

Mobius can assume an immense Artificial Honkai body in combat.

• Easily destroyed Seaborn creatures with her scepter and overwhelming physical strength. 223
• Withstood venomous stingers, toxins, and corrosive attacks that would kill ordinary people. 223
• Used the form to infiltrate the Deep Sea Church’s underground laboratory, rescue Laurentina, and defeat Quintus. 223

Equipment / Items

• White lab coat — her usual research attire. 20 93
• Mobility device — made by Vill-V to help her move efficiently in her smaller form. 93
• Scepter — used in her Artificial Honkai form against Seaborn creatures. 223
• Specialized data device — carried as part of her preparations for negotiations with Kristen Wright. 127
• Abyss Flower research setup — works with Bianca to test the destruction of Originium. 109

Relationships

• Griseo — Mobius is one of Griseo’s unlocked identities; they share a synchronized will and telepathic connection despite being distinct consciousnesses. 19 20
• Sakura — A linked identity and frequent partner. Sakura gathers intelligence, provides logistical support, summons Mobius when discretion is needed, and assists her research. 64 115
• Ifrit — Mobius’s “little white mouse” and treatment subject. Mobius initially manipulates Ifrit into cooperating, but develops medicines to ease her pain and acts protectively toward her. 94 100 117 140
• Bianca — Research collaborator and frequent target of Mobius’s teasing. Bianca assists with experiments involving Abyss Flower and provides practical support for Mobius’s work. 108 109 115
• Ho'olheyak — A wary transactional associate. Mobius trades answers for favors, uses Ho'olheyak’s intelligence network, and repeatedly offers to make her a research subject. 106 107 124
• Kristen Wright — Cooperation partner at Rhine Lab. Mobius negotiates privileges and cover for her work while revealing that she can cure Originium infection under limited conditions. 128 140
• Maria Nearl — A Kazimierz test subject whom Mobius deceives, examines, and uses for an unlocking procedure. 64 65
• Laurentina — An Abyssal Hunter rescued from the Deep Sea Church. Contact with Laurentina unexpectedly begins unlocking Aponia’s Discipline. 223 224
• Pardofelis — An informant used by Mobius to investigate Quintus and the Deep Sea Church’s hidden laboratory. 222

Story Role / Major Arcs

• Kazimierz journey — Travels with Sakura to Kavaleriel to raise research funds and study the region. Mobius tests Maria Nearl, collects Terran samples, and later leaves Kazimierz with Bianca’s blood sample and research funding. 64 65 76
• Rhine Lab and the Ifrit mission — Joins the Structural Department, accepts a mission to cure Ifrit’s Originium infection, and begins covert examinations and treatment development. 93 94 100
• Ho'olheyak’s bargain — Establishes an exchange of knowledge for services with Ho'olheyak, using her to gather intelligence and keep other investigators away. 106 107 124
• Rhine Lab cooperation — Negotiates with Kristen Wright, reveals her limited ability to cure Originium infection, and seeks conditions that will make her future research and movements easier. 128 140
• Saltwind City operation — Sends Pardofelis to investigate Quintus, infiltrates the Deep Sea Church, destroys its Seaborn laboratory, defeats Quintus, and rescues Laurentina. 222 223

Notable Quotes

“Hehe, this feeling is truly wonderful~” 20

“I don't need friends...” 97

“It's just that your wish to pursue [Yesterday] seems a little ridiculous before me, an emblem of [Infinity], one who pursues endless evolution.” 107

Trivia

• Mobius uses popping bubble wrap as one of her few stress-relief methods. 96
• She wishes for an assistant like Klein, but recognizes that recreating one in Terra would require extensive experimentation and may not succeed. 95 96
• Her pursuit of cleanliness is strong enough that she normally allows energy to leak from her body simply to remove nearby Originium dust. 98
