Lin Ze

Biodata

Power Progression

The documented progression consists of combat-driven growth, newly learned spells, and transformations rather than named ranks.

Background / History

Transmigration and Auror service

Before arriving in the wizarding world, Lin Ze lived in a world where Harry Potter existed as films. He loses consciousness while rewatching them in his rented room and awakens on September 29, 1981, shortly before the deaths of Harry Potter's parents and Voldemort's first downfall 1.

He takes over the life of another Lin Ze, a conflict-averse Hufflepuff whose girlfriend had pushed him into becoming an Auror. Unlike the body's original owner, the newcomer begins exploiting its combat-growth talent. His initial priority is securing resources and becoming strong enough to protect himself, not saving Harry's parents or preserving particular people's fates 2 4.

Death Eater investigations

Lin Ze establishes himself by capturing three Death Eaters in Knockturn Alley. After Dorcas Meadowes's funeral, Scrimgeour transfers him to the Records Management Office to keep him away from the front lines. Lin Ze instead sees the Ministry's accumulated records as a valuable resource 3 22.

He later draws his wand against a gathering of at least thirty Death Eaters in Diagon Alley. Following Voldemort's downfall, he returns to the Auror Office as assistant leader of the new Special Operations Team, tasked with investigating Death Eaters and their associates; he already has a substantial list of targets 27 33.

His investigations extend beyond Britain. During an official visit to France, Mr. Delacour tells him that at least three groups of British Death Eaters have attempted to enter the country. In a subsequent factory battle, Lin Ze retaliates against Richard's torture with Unforgivable Curses of his own 48 52.

Pettigrew, Aila, and Rodna

Lin Ze discovers that Percy's pet rat, Scabbers, is an Animagus and takes him into Ministry custody, compensating Percy with Galleons. Later, he gives Sirius the route for Peter Pettigrew's transfer and secretly follows the escort to Yorkshire, where masked attackers ambush it 70 77.

While pursuing information abroad, he encounters Aila, an abused child whose Obscurial power overwhelms his defenses and drains his magic. He subsequently takes her away from the inn where she had been staying 80 82 84.

An investigation with Fudge brings Lin Ze into conflict with Rodna Grindelwald. Despite growing stronger during their duel, Lin Ze is overpowered; Rodna becomes interested in his unusual magical circuits. Their later dealings give Lin Ze access to Boundary Break and the black-bound notebook containing further spells 98 99 102 122.

Brazil and the Dragon King Bloodline

Seeking help for Aila, Lin Ze tracks Newt Scamander through Manaus and upriver toward São Gabriel. After a confrontation with a vampire, Newt treats his injuries and agrees to visit the eight-year-old Obscurial in Godric's Hollow 115 118 123 124.

Lin Ze subsequently develops scales, altered pupils, and wings. With Rodna present, he learns to control the transformation and discovers that the physical enhancement persists even when his scales are hidden 129 131 133.

Team Three and the blood-race investigation

As Team Three struggles to recruit against Moody's and Amelia's teams, Lin Ze offers Barty Crouch Jr. a position. Scrimgeour approves the transfer but makes Lin Ze responsible for any resulting problems 146.

A Corpse Vine investigation connects seven disappearances to the area around Delis Secondhand Shop and Slinger Alley. Lin Ze, Barty, and Mia encounter a hostile black mist during a stakeout; the ensuing battle tests his dragon-enhanced body and culminates in his evacuating both companions through Boundary Break 152 154 156 157.

While investigating Evan Rosier's death, Lin Ze finds a notebook marked “Our blood hasn't dried yet” and captures a woman whose Blood Leech Ring kills her before questioning. His inquiries lead through a blood-harvesting organization, the Mulciber family, and historical accounts of a vampire lair beneath the Icon Church. After the dock operation, he publicly rejects the suggestion that Muggles themselves constitute a threat 161 168 170 173 186.

The veil and King Arthur's era

Denied access to the Department of Mysteries, Lin Ze pursues other leads concerning the Invisible Veil. Sirius recalls hidden steps at Tintagel, while Quinn seeks a Durmstrang text describing a curtain between the living and the dead 207 208.

Lin Ze's later travels take him to King Arthur's era. He fights witch hunters, is welcomed as the Dragonborn in Whitewater Valley, and travels with Saira. A forest illusion recreates his former home and parents, but he rejects it rather than remain inside the false reunion 220 223 227 231 289.

Morgana impersonates Saira and deduces that Lin Ze comes from the future. He later frees Sirius from a palace prison and fights Shedding Gods alongside Sirius and Arthur. After returning, he resumes Ministry work while acknowledging that Mia may have arrived at another point in time 252 262 280 289.

Return to Ministry operations

Evidence supplied by Caractacus Burke leads Lin Ze to confront Lucius Malfoy directly. He destroys the manor's gates and defenses, then lets Lucius attempt three spells before attacking; the Cruciatus Curse and Killing Curse shown do not affect him 290.

He subsequently rescues Ben and Weiqi from gray-cloaked attackers, defeats the forces inside a shop, and traps the remaining alley fighters with a Ground-Sinking Charm. In a later tunnel fight, he uses his dragon-enhanced body to disrupt a crowd of more than forty wizards at close range 299 301.

Appearance

• Human appearance: A youthful East Asian man with black hair, black eyes, thick eyebrows, and smooth cheekbones. At eighteen, his face looks slightly younger than his age 15 129 220.
• Dragon scales: Closely packed jet-black scales edged in dark gold. They initially cover his hands, arms, and small areas near his ears and temples; he later manifests full-body coverage 129 154.
• Eyes: His transformation introduces golden rings within his otherwise black pupils 129.
• Wings: Large black wings likened to soaked sails 131.
• Clothing: Purchases a dark-gray wool-blend coat and dragon-hide boots after receiving fifty Galleons. Uses a dark-gray hooded cloak to conceal most of his face during investigations 10 74.

Personality

Lin Ze is openly pragmatic about survival, money, and advancement. He initially refuses to take responsibility for changing the tragedies he knows are approaching, preferring to accumulate resources and strength. Even after gaining influence, he remains conscious of the difference between his finances and Sirius's inherited wealth 4 289.

His caution coexists with a growing appetite for combat. His hands shake from excitement rather than fear during his first Death Eater battle, and prolonged fighting against Rodna makes him increasingly exhilarated. Nevertheless, he retreats when necessary and takes precautions around potentially cursed objects 3 98 102.

He frequently taunts enemies, invents cover stories, and uses theatrical deception. He mocks masked Death Eaters, stages damage to suggest a difficult battle, and poses as an investor while investigating a concealed room 3 110 204.

His methods can be brutal: he beats and wounds Bali Kochas during questioning and uses all three Unforgivable Curses in the supplied chapters. He also protects particular people, seeking specialist help for Aila and rescuing Sirius, Ben, and Weiqi 52 124 223 262 299.

Abilities & Skills

Combat-driven growth

His body's innate talent improves magical power and spell proficiency through fighting 2.

• Produces surges through his magical core and circuits during difficult battles 3 98.
• Can accelerate his casting as an exchange continues 98.
• Includes combat-triggered magical recovery, demonstrated after his reserves are nearly exhausted 103.
• Does not prevent depletion or defeat: early anti-Apparition magic drains him heavily, and Rodna still overwhelms him 3 99.

Spellcasting and battlefield control

Lin Ze combines rapid spell exchanges with terrain manipulation and close-range attacks 3 299.

• Nonverbal and wandless casting: Uses fast silent disarming and impediment spells, wandless fire spells, and eventually wandless Dawn 3 155 156 222.
• Defensive magic: Uses Shield Charms and raised stone walls; a physical wall intercepts a Killing Curse during his first Death Eater fight 3.
• Restraint: Employs petrification, conjured bindings, vines, and magical handcuffs 3 223 299.
• Terrain control: Makes floors slippery, contracts a passage with Transfiguration, and collapses paving beneath opponents 52 103 299.
• Fiendfyre: Uses it offensively, but on one occasion retains only enough control to throw the growing flames into a spatial void 233 299.

Boundary Break

Boundary Break, cast as Aperi-Limes, tears open spatial rifts edged with blue-white electrical arcs 102.

• Bypasses defenses that block Apparition 102.
• Requires a destination to be pictured; his first attempt opens over a bottomless abyss when he neglects this 102.
• Allows rapid repositioning and the evacuation of companions 157 299.
• Initially permits only two consecutive casts before depletion; a later cast costs one-third of his reserves 102 254.

Dawn

Dawn is a light-producing spell learned from Rodna's black-bound notebook. Lin Ze first succeeds by recalling happy memories of defeating dark wizards and taking their gold 122.

• Initially manifests as an enormous light sphere that becomes a phantom goddess 122.
• Can consume magic dangerously quickly, forcing him to stop the first successful casting 122.
• His first wandless version produces dark-golden light without the goddess and evaporates part of a black-water attack 156.
• The initial wandless success does not establish that every later casting lacks the phantom; it appears again during the forest encounter 235.

Dragon King Bloodline

The bloodline provides scales, enhanced physical performance, and a violent magical nature capable of scorching hostile black mist 133 154.

• Can summon and dismiss scales consciously, including full-body coverage 133 154.
• Grants powerful leaps, rapid movement, and sufficient strength to break magical shackles 155 262.
• Lets him withstand clubs and edged weapons even while a suppression device prevents ordinary spellcasting 235 236.
• Deflects spells and enables him to fight groups at close range without relying on spell exchanges 299 301.
• Limits: His scales are not indestructible; black water shatters the scales on his fingertips and badly injures the flesh beneath 156.

Unforgivable Curses and curse resistance

• Cruciatus Curse: Cast against Richard after Richard tortures him 52.
• Killing Curse: Used against Richard, Rodna, and a vampire; the vampire continues attacking after a direct hit 52 98 120.
• Imperius Curse: Used on a palace guard to obtain directions to Sirius's prison tower 262.
• Resistance: Lucius's Cruciatus Curse and Killing Curse fail against him, but the supplied account does not establish universal immunity to every caster or circumstance 290.

Investigation and infiltration

• Uses detection magic to identify Scabbers as an Animagus 70.
• Alters his facial features, hair, clothing, and apparent identity for undercover work 168 222 274.
• Uses Disillusionment and a facial Blur Charm to conceal himself 102 223.
• Draws on Ministry archives, informants, family records, and crime-scene evidence 22 74 161 173.
• Has studied Ancient Runes, but cannot automatically identify unfamiliar historical formations 246.
• Retains knowledge of the Harry Potter films, though Rodna's existence and powers fall outside what he remembers 1 99.

Equipment / Weapons / Items

• Wand — His principal spellcasting tool, used alongside physical attacks and wandless magic 3 299.

• “Life” finger bone — Obtained from Mordred after Lin Ze agrees to take him to see his teacher 285.

Relationships

• Olivia Delacour — Girlfriend inherited with the original Lin Ze's life. Their relationship had lasted two years by his conversation with her father; his initial failure to answer her letters stems from not knowing about it after transmigration 11.
• Mr. and Mrs. Delacour — Olivia's parents host him in London and Paris. Mr. Delacour discusses security concerns and official travel with him 11 48.
• Rufus Scrimgeour — Superior who moves him away from frontline danger, later appoints him assistant team leader, and holds him accountable for recruiting Barty 22 33 146.
