Zuo Zuo

Biodata

Power Progression

Background / History

Zuo Zuo initially understands herself as a mutant born when Lynn’s extensive use of Flesh Regeneration Potion caused flesh and Soul Fragments to fuse through a series of coincidences. She shares a symbiotic existence with his body and initially believes she cannot survive apart from him 283.

Her consciousness is unusual even by mutant standards: she can speak clearly from birth and already possesses mature understanding rather than developing gradually. Lynn first suspects a connection to the Colossus Heart, then identifies her as its true consciousness—the Queen whose place he has occupied 463 689.

Returning to the Colossus could restore what she has lost and allow her to become one of its great being’s twins again. When Lynn attempts to leave her there, she angrily rejects his decision to choose her future without asking her 694 695.

Their earliest relationship is openly hostile. Lynn later recalls that they fought with knives, trying to cut one another off, before gradually reaching an agreement and becoming accustomed to each other 2419.

Appearance

• Ordinary form: Lynn’s animate left hand, capable of speaking, biting, and expressing emotion through its movements 109 110.
• Humanoid form: A petite, black-haired girl with long hair and a sharp canine tooth. She ties her hair into two ponytails for combat 464 466 1505.
• Combat clothing: A pure-black outfit created by Lynn through Mimicry 464.
• Curse Seal: A pitch-black sigil on the back of her hand. In human form, its dark patterns spread across her back and cannot be rubbed away 1505.
• Altered flesh: Can become black slime, extend her arm, or reshape a limb into a weapon 113 466 513.

Personality

Zuo Zuo is outspoken, proud, quick-tempered, and reluctant to admit affection. She habitually calls Lynn “Head,” “Brain,” or “Blockhead,” mocks his pretensions, and responds to his provocations with punches or bites. Her bravado has limits: she fears Xiao Xiao and becomes frightened when alone in an unfamiliar consciousness space 110 320 538 654.

She knows Lynn well enough to recognize many of his schemes, but his displays of vulnerability can still deceive her. She is particularly guarded against unwanted transformations and intimacy, actively resisting his attempts to use Mimicry on her and becoming delighted when he commits to abstinence 528 537 538 897 1805.

Her loyalty is strongest when Lynn is in danger or despair. She refuses to accept being abandoned “for her own good,” insists on sharing his burdens, and challenges his belief that he must protect everyone alone. Despite her teasing, she recognizes the kindness beneath his selfish behavior and becomes an increasingly disciplined fighter so she can remain beside him 1238 1240 1365 1993 2305.

Abilities & Skills

Flesh Transformation and Regeneration

• Dissolves into black slime and reforms as Lynn’s left hand 113.
• Lengthens her arm to move objects or catch distant surfaces, including a protrusion on the Abyss’s wall 513 1584.
• Reshapes her arm into an exceptionally sharp spear 466.
• Uses Lynn’s Flesh Cataclysm to assume a humanoid body 1505.
• Can interrupt Lynn’s attempt to transform her with Mimicry by biting his casting hand 538.

Devouring and Internal Storage

• Ate a Flesh Puppet from the inside out shortly after her birth. Lynn consequently suspects her digestive capacity may be extraordinary, but the passage does not establish an absolute limit 464.
• Opens a large maw capable of swallowing a Flesh Humanoid’s upper body 932.
• Stores rather than digests selected objects, including coins, potions, grenades, mechanical parts, and a three-meter saber 514 515.
• Keeps a private stash of Mental Potions and retrieves them to revive Miss Nature 1365.

Colossus Heart Authority

• As the Heart’s consciousness and one of the Colossus Twins, possesses one of the Colossus’s two highest levels of internal authority 1506.
• Has complete affinity with the Colossus Heart. The Curse Seal provides a shortcut for releasing its power according to her will 1506.
• Channels blood energy into flesh weapons with enormous destructive force 1506.
• Limit: The incomplete Heart is described as infinitely close to Origin rank, not an independent Origin. Restoring it and returning Zuo Zuo’s consciousness to it could eventually make her the Colossus’s second Origin 1506 1507.
• Vulnerability: Resonance through the Colossus’s Transdimensional Link exposes her to Blood Core’s pain and death impulse. Lynn’s shielding reduces, but does not immediately eliminate, the shared pain 2218 2220.

Saber Technique and Blade Intent

• Combines evasive movement, rapid cuts, and precision thrusts; her early control training emphasizes restraint rather than indiscriminate power release 1509.
• Models her drawing technique on the extraordinary Left Hand witnessed in Raven’s illusion 1993 2042.
• Devotes herself to blade intent while Lynn divides his attention among numerous laws 2220.
• Uses Draw-Cut to concentrate her attack into a limb-severing strike 2220.
• Receives the Captain’s recognition that her perseverance could make her formidable in any past era, even without relying on Lynn 2096.

Shared Power and Independent Existence

• Shares “one body and two souls” with Lynn and remains in daily contact with his master’s power 2023.
• Can exist independently of him by the time of their prolonged training in the past, but still returns to hand form to sleep on his lap 2042.
• Can wield Lynn’s Firstborn and Trinity power when he permits it 2247.

Practical Support

• Provokes Lynn into fighting a curse-induced loss of motivation by swallowing his money and moving the remaining coins out of reach 513.
• Proposes keeping past time rifts open but sealed against enemies, giving Lynn more time to train 2039.
• Escapes the Nether Sea’s mental bewitchment and repeatedly calls and slaps Lynn until he awakens 2191.

Equipment / Weapons / Items

• Night Demon Blade — Given to her by Lynn; used against mechanical beetles, during precision training, and against later threats 464 466 1509 2216.
• Curse Seal — Bound to her by Lynn to accelerate access to the Colossus Heart’s power 1505 1506.
• Flesh blade — Forms through the Colossus Heart’s power and carries its blood energy 1506.

• Kitchen knife — Kept beneath her pillow to cut Lynn’s intrusive tentacles 850.
• Mental Potions — Her personal reserves include inferior, legendary-, Lynn’s custom deluxe, and anti-Zuo Zuo pesticide editions 1365.

Relationships

• Lynn — Her host, beloved companion, and fellow “accomplice.” Their bond includes affection, quarrels, deception, and repeated conflict over his coercive behavior and attempts to leave her behind. He calls her someone he loves; their system relationship reaches “Intimate+” 538 863 1240 2645.
• Colossus Brain — Her counterpart among the Colossus Twins. Zuo Zuo recognizes her as the Colossus’s first owner and the god who previously tried to take her from Lynn’s body. Brain’s fine control of Colossus power becomes a benchmark for her training 758 1506 1509.
• Xiao Xiao — Initially a source of intense fear. Later, Zuo Zuo challenges the Witch God Head’s attempt to arrange Xiao Xiao’s marriage without consulting those involved 110 2131.
• Sir Awen — Confirms her identity through psionics inside Ether’s Spirit World and supports her attempt to reach Lynn’s imprisoned soul fragment 1991 1993.

• Miss Nature / Mother Tree of Desire — Zuo Zuo revives her while seeking help against Lynn’s curse. After an uncontrolled kiss, Zuo Zuo persuades her to help bring Lynn to them 1365 1366.
• Ether — Devours her along with Lynn’s body and uses the threat of torturing her to force Lynn into supplying Firstborn Power 1991.
• Captain — Praises her sustained training and potential to become independently formidable 2096.
• Feather Pen — Throws her out after she criticizes and acts out an alternative ending to a story draft 2706.

Story Role / Major Arcs

Early Partnership and Mechanical Battles

Zuo Zuo grows from an argumentative left hand into an active member of Lynn’s fighting team. In humanoid form, she attacks mechanical beetles with the Night Demon Blade and her own transformed flesh, earning experience for Lynn through her kills 464 466.

She also repeatedly forces him back into action. When a curse strips away his fighting spirit, her deliberate consumption of his savings pushes him to activate Limited-Time Curse Removal on himself 513.

Blue Star and Refusal to Be Abandoned

Believing Lynn dead during the Flesh Dominator crisis, Zuo Zuo alters a summoning array and reserves Leviathan Flesh for a desperate detonation, declaring that she no longer cares if everyone dies 1055.

Later, she falls toward the Deep Sea after believing Lynn has once again excluded her from his final gamble. He catches her and takes her with him; afterward, she demands that he never leave her alone again 1238 1239 1240.

Ether’s Spirit World

After Ether devours Lynn’s body, Zuo Zuo’s soul remains trapped within its Spirit World. Sir Awen’s examination of her memories reveals that Lynn endured torture but surrendered when Ether threatened to repeat those torments on her 1991.

With Sir Awen and Silver Fantasy waiting below, she climbs toward Lynn’s imprisoned soul fragment and vows to become strong enough to match the Left Hand seen in the Old Days illusion 1993.

Training Beyond Ordinary Time

When Lynn despairs over his inability to turn Firstborn Power into rules quickly enough, Zuo Zuo proposes remaining in the past. They train together in an era 210,000 years earlier: he studies the God King’s use of laws while she relentlessly practices her blade technique and quietly cares for him during his meditation 2039 2042.

Her later combat contributions include weakening a calamity’s pressure with an imprint-infused slash and fighting Blood Core despite suffering the pain of their attacks through resonance 2216 2220.

Separation in Outside Time

Zuo Zuo carries the sleeping Lynn through the frozen void toward the colorful River of Time, then disappears. He breaks the time barrier and searches for ages, growing old without finding her 2419.

He eventually finds her but initially withdraws rather than bring her back into a reality approaching catastrophe. When she finally awakens, she discovers that his hair has turned completely white and embraces him in tears 2577 2643.

Final Companionship and the Time War

Zuo Zuo promises to accompany Lynn to the end and becomes his left hand again—his last remaining attachment within the dream of order. Though grieving their lost companions herself, she continually interrupts his brooding and draws him out of isolation 2645 2646.

As the time war changes Dark Night City’s history, her memories also change; Blood Saw, the Dollhouse, and Miss Doll become unfamiliar or indistinct to her 2659.

Near the ending, she joins a reunion of Dark Night City’s old companions before returning alone to the Potion Shop. The final chapter restores her familiar quarrel with Lynn, who accuses her of getting drunk instead of buying supplies 2706 2707.
