Power Progression

Background / History

Lei En was a five-year-old orphan and transmigrator when he witnessed Gol D. Roger’s execution in Loguetown. He used the chaos following Roger’s final declaration to check in at the execution platform, receiving Roger’s Peak Swordsmanship. The passive immediately reconstructed his body and sharpened his perception beyond normal human limits. Soon afterward, he killed the pirate “Black Wolf” Barrett with a wooden stick and declared himself effectively invincible within East Blue. 1 2

After leaving Loguetown, Lei En traveled to Shimotsuki Village and entered One-Heart Dojo. He easily defeated Kawashima, the dojo’s strongest apprentice, then humiliated Kuina in a sparring match while identifying her fear that her gender would prevent her from becoming the world’s greatest swordsman. Later that night, he used Shave to rescue her from a fatal fall, altering her fate and receiving Yubashiri and a Marrow-Cleansing Pill as rewards. 3 4

Lei En gave Kuina the Marrow-Cleansing Pill, transforming her constitution. She swore lifelong service as his sword attendant, while he remained at Shimotsuki Village for several years of training. At age eight, he and Kuina set sail, later recruiting former Marine sniper Dadi as helmsman in exchange for protection for Dadi and his daughter Carol. 5 9 10

Seeking the Rumble-Rumble Fruit, Lei En led his group through the Knock Up Stream to Sky Island. He located the fruit with Observation Haki, consumed it in front of Enel, and awakened max-level lightning control without normal Devil Fruit weaknesses. He defeated and coerced Enel into signing a lifelong Heavenly Court labor contract, then overthrew Gan Fall and renamed Angel Island Heavenly Court Headquarters. 11 17

At Shandora, Lei En used electromagnetic force to collect its gold, rang the Golden Bell so that its toll reached Jaya, and commissioned a flying ark that became the Heavenly Court Thunder God. With Sky Island secured and immense wealth acquired, he returned to East Blue to recruit useful figures and train future major pirates. 18 19

In East Blue, Lei En treated early pirates and future major figures as targets for amusement, recruitment, and conditioning. He humiliated Alvida, trained Luffy, Ace, and Sabo through extreme electrical and Seastone-based regimens, subjugated Buggy and Kuro, and intervened in Cocoyasi Village to free Nami from Arlong’s rule. Nami subsequently joined Heavenly Court as chief steward after Arlong’s death and Nezumi’s punishment. 20 26 35 50 53

While crossing the Grand Line, Lei En defeated Crocodile, liberated Alabasta from Baroque Works, recruited Nico Robin as Heavenly Court’s first intelligence officer, and accepted Vivi’s allegiance and affection. He later crushed CP9 at Water 7, stormed Enies Lobby, rescued Robin from the World Government, and erased a Buster Call with Myriad Thunder: Divine Judgment, leading to his 1.5-billion-Beli bounty and designation as an Enemy of the Gods. 79 80 90 102

Lei En’s escalating conflict with the World Government included defeating Rob Lucci, intimidating Admiral Kizaru into fleeing, forcing Rayleigh to recognize Roger’s swordsmanship in him, incorporating the Kuja Pirates under Boa Hancock, and openly breaking into Impel Down to confront its defenses. During the Marineford conflict, he rescued Ace, defeated Blackbeard, extracted Teach’s Dark-Dark Fruit, and executed Teach rather than accept his surrender. 90 121 123 130 134 157 158

After extending Heavenly Court into the New World, Lei En defeated and subordinated Kaido and Big Mom, removed Doflamingo from Dressrosa, punished Ryokugyu with a century of forced reforestation labor, and imposed his own financial and administrative order over former pirate and Marine territories. He repeatedly stated that his goal was not merely to become Pirate King, but to overturn the World Government’s hierarchy and establish a new world order under Heavenly Court. 176 192 213 236 295

Lei En formally declared war on the World Government through a global broadcast, gave the Five Elders a ten-day ultimatum to surrender Imu and the Empty Throne, and led the Heavenly Court Thunder God against Mary Geoise. He intercepted Uranus, defeated the Five Elders in their transformed forms, awakened Thunder Law, and ultimately killed Imu with the Supreme Thunder God Sword. 213 222 230 236 237

Following the fall of Imu and the Celestial Dragons’ regime, Lei En became the undisputed ruler and public “Thunder God” of the world. He centralized the world’s wealth under Heavenly Court, established tribute obligations for affiliated islands, repurposed Mary Geoise into a history museum documenting Celestial Dragon crimes, and rebuilt Ohara’s All-Knowing Tree Library so Robin could preserve and publish the true history. 264 322 330 334

After exhausting the world’s known threats, Lei En expanded Heavenly Court beyond Earth with the Heavenly Ark, fought cosmic pirates and alien life forms, and turned his attention toward extraterrestrial worlds. He later became a father to Heavenly Court’s crown prince, whose extraordinary inherited Haki enabled him to awaken the Dark-Dark Fruit at only three years old. Lei En immediately began imposing his own brutal training philosophy on the child, though Boa Hancock fiercely opposes his methods. 320 322 347 351

Appearance

Lei En initially appeared as a skinny, dirt-smeared five-year-old in ragged burlap clothes. Following the fusion of Roger’s Peak Swordsmanship, his black eyes became unusually sharp and weathered. As he grew, he became taller and more muscular, usually dressing in black and carrying Yubashiri at his waist. 2 9 19

• Black hair and deep black eyes that turn azure when he channels lightning. 14 18
• Often wears a black training outfit or black trench coat. 9 26 50
• Carries himself with an intimidating calm despite his youth. 2 13
• Commonly keeps both hands in his pockets when confronting enemies. 2 32
• As Heavenly Court’s ruler, often sits on a gold Thunder God throne and wears a black trench coat, leather boots, or casual black clothing even at formal events. 247 264 343
• His awakened Thunder Law can dissolve both his body and Yubashiri into black-red particles of thunderous light. 236

Personality

Lei En is intensely self-assured and openly arrogant. He refuses to serve under stronger established figures, rejecting Shanks’ invitation and Garp’s Marine recruitment offer because he intends to stand at the top himself. His ambition is not limited to personal power: he explicitly plans to build and expand the Heavenly Court. 6 17 24

He is driven as much by amusement as by conquest. Rather than immediately challenge the New World’s leading powers, he returns to East Blue to interfere with villains and future protagonists while they are still weak. He regards figures such as Luffy, Zoro, and Nami as pieces in an entertaining future he wants to shape. 19 48 50

Lei En can be protective and generous toward people he values, saving Kuina, offering Dadi and Carol safety, and attempting to restore Zeff’s lost leg. However, he is also ruthless toward opponents and subordinates: Enel, Buggy, Kuro, and his trainees are subjected to violence, humiliation, or coercive labor contracts when they resist him. 4 10 16 34 42

His hostility toward the World Government hardens into open revolutionary ambition after Robin’s recruitment and the Enies Lobby incident. He considers the Marines’ justice a tool of Celestial Dragon oppression, rejects the title of Pirate King as insufficient, and seeks to destroy the old global order rather than merely rule within it. 80 102 213 236

Despite his cruelty and authoritarian habits, Lei En has a personal sense of responsibility toward people he accepts as his own. He protects Robin’s pursuit of history, frees oppressed populations such as Alabasta and Cocoyasi, creates institutions to expose the Celestial Dragons’ crimes, and reacts with immediate seriousness when Heavenly Court personnel or his family are threatened. 53 80 330 334 350

Lei En becomes noticeably flustered by persistent romantic attention from Hancock and other close women, often choosing escape over confrontation. His conduct as a father is similarly contradictory: he is proud of his crown prince’s potential, yet considers painful electrical conditioning an appropriate foundation for the child’s growth. 248 314 347 351

• Has access to system storage, Devil Fruit extraction, and check-in rewards that have repeatedly supplied weapons, medicine, Devil Fruits, and power upgrades. 4 10 158

• Possesses omniscient perception following this fusion, allowing him to sense individuals and events across the world simultaneously. 264

Physical Ability and Mobility
