Gerald

Biodata

Power Progression

Background / History

Gerald is reincarnated into the world of Harry Potter with memories of his previous life, including knowledge of the books and games. He initially believes he lives in an ordinary version of 1989, despite possessing a cultivation panel and practicing the Divine Firmament Five-Elements Heavenly Thunder Art from early childhood. His Hogwarts acceptance letter reveals the setting’s magical nature 1 4 7 8.

He loses both parents while young but grows up with affection and support from Henry Hall and the surrounding family. Before Hogwarts, he tends sheep and makes Henry’s breakfast. When he splits a log with one palm strike at eight years old, Henry tells him to conceal his strength 1 6 34.

On the journey to King’s Cross, Uncle Jack reveals that Gerald’s father, Victor, and his biological grandfather died in an explosion in London’s West End eight years earlier. Gerald suspects a connection to Peter Pettigrew, but the cause remains unconfirmed; investigating those deaths becomes one reason he resolves to capture Pettigrew 9 50.

Possible Green Family Ancestry

While researching alchemy, Gerald finds a manuscript bearing Braid Green’s name. Further reading identifies the Greens as a medieval pure-blood family renowned for alchemy, founded by Gawain Green (1342–1419). The family declined in the early eighteenth century, and Braid, its last known member, died in 1798 without documented descendants. Gerald suspects a connection to his own family and hopes to collect their surviving manuscripts, but his descent is not established 39.

Appearance

• Facial features: Clean features, a high nose bridge, and two dimples when he smiles 2.
• Height: Slightly over 1.7 meters at eleven; his height helps him pass as older while wearing a hooded cloak 31.
• Compared with his classmates: About half a head taller than Fred and George during the start-of-term feast 14.
• Distinguishing disguise limitation: Aberforth identifies him as a teenager from his smooth, unscarred hands despite his concealed face and muffled voice 31.

Personality

Gerald is disciplined and strongly motivated by interest in supernatural abilities. He maintains both cultivation and magic practice, studies in the library until closing, and alternates activities rather than stopping when one becomes tiring. His previous life’s demanding work schedule makes repeated practice seem comparatively enjoyable 8 9 33.

He is pragmatic about money and resources. He chooses secondhand robes, sells medicinal liquids, and learns alchemy from Fred and George partly because their instruction is free. His financial ambitions also reflect gratitude: he wants to expand Henry’s farm and hire workers so the old man can rest 5 7 31 32.

Initially, Gerald prioritizes secrecy and controlled growth over involvement in the original story. He avoids revealing his foreknowledge and worries that Snape might uncover his memories through Legilimency. By Christmas, concern for Harry and the need to investigate his family’s deaths outweigh his fear of changing the timeline 11 15 21 50.

His politeness does not prevent forceful retaliation. He treats Ron attentively and helps other students, but throws Montague out of a classroom to discourage further harassment and threatens the Dursleys when confronting Harry’s abuse 6 12 19 50.

Abilities & Skills

Divine Firmament Five-Elements Heavenly Thunder Art

Gerald’s cultivation art develops his body before refining accumulated essence into primordial qi. Its later stage combines the five-element qi of the organs to nurture thunder within his dantian 8 36.

• Mountain-Holding Fist: A foundational body-refinement method using movement and breathing to temper muscles, bones, skin, and flesh 8.
• Superhuman strength: Before Hogwarts, he can lift almost 500 pounds with one hand and shatter a three-foot-tall boulder with one punch 1 8.
• Fine temperature perception: Ninth-level body refinement gives him near-instinctive awareness of small temperature changes, assisting alchemical work 32.
• External qi absorption: Aperture Opening allows him to absorb spiritual qi directly instead of relying primarily on food and medicinal herbs 36.
• Reduced need for rest: After the breakthrough, he can go dozens of days without sleep or rest without fatigue, although he still prefers sleeping normally 36.
• Breakthrough danger: Refining essence into qi requires careful control; excessive heat can sever his meridians, while insufficient heat leaves the transformation incomplete 36.

Cultivation Panel and Spiritual Perception

The panel records Gerald’s cultivation and identifies spiritual herbs, artifacts, medicinal products, and talismans. Spiritual sense and the Qi-Perception Spell extend his awareness beyond what the panel alone provides 4 8 36 40 44.

• Spiritual sense: Lets him perceive his surroundings in fine detail with his eyes closed; he uses it to improve talisman drawing and expects it to benefit potion-making and alchemy 36 39 44.
• Qi-Perception Spell: Detects spiritual plants within his field of vision or spiritual-sense range, whereas the panel requires him to focus directly on a plant 40.
• Magical-strength estimation: Compares wizard auras; Flitwick and Snape appear much stronger than students, with faint black wisps edging Snape’s aura 37.
• Creature detection: Reveals approaching Acromantulas as pale red points before combat 40.

Cultivation Spells

Aperture Opening unlocks the Fireball Spell, Water Arrow Spell, Thunder Invocation Spell, and Qi-Perception Spell 36.

• Fireball Spell: Produces a basketball-sized fireball. Within five attempts, Gerald can make it circle his body rather than merely hover above his palm 36.
• Water Arrow Spell: Successfully cast on his first attempt after the breakthrough 36.
• Thunder Invocation / Thunder-Summoning Art: Successfully cast on his first attempt and later used in lethal combat against Acromantulas 36 40.
• Rapid activation: Fireball and thunder techniques require no spoken incantation, but consume large amounts of primordial qi 40.
• Trace avoidance: He uses cultivation techniques outside Hogwarts without triggering the restrictions attached to ordinary underage wizard magic 50.

Wizard Magic

Gerald rapidly learns beginner spells after blood-binding his wand, but stronger magic still requires practice and sufficient magical power 7 8.

• Casting-speed weakness: His wand spells still require spoken incantations during the Acromantula fight. Nonverbal and wandless wizard magic remain goals rather than documented skills 40.

Medicinal Refinement and Alchemy

Gerald recognizes similarities between wizard potion-making and cultivation alchemy, then studies both to improve extraction, manufacture useful items, and earn money 24 25 33.

• Runic alchemy: Learns material purification, rune tracing, magic channeling, and connected rune circuits from Fred and George 32 33.
• Artifact design: Builds a magical notebook with information-storage, reading, and feedback sections using multilayer rune structures 45 46.
• Herb cultivation: Successfully propagates Ironwire Vine and grows Heaven-Subduing Flower with Sprout’s assistance 33 41.

Talisman Crafting

Gerald draws talismans using yellow paper, cinnabar, and dragon-blood ink. Spiritual awareness improves his brush control and qi infusion, though his first session’s Object-Storing Talisman success rate remains below ten percent 41 43 44.

• Harry Potter — Gerald chooses to help him before Hogwarts, explains his magical identity, and confronts the Dursleys over his treatment 49 50.
• Peter Pettigrew — Intended capture target. Gerald knows his identity and survival, recognizes the rat in Percy’s pocket, and suspects a possible connection to his family’s deaths 9 35 39 50.
